Describe how you would convince a friend that sin(x + y) does not equal sin x + sin y.
Answer:
Let's start first with sin(x+y) :
sin(x+y) sin(x)*cos(y)+cos(x)*sin(y)Now with sin(x)+sin(y) :
sin(x)+sin(y) 2*sin[(x+y)/2] * cos[(x-y)/2]We can see that both expressions are far away from being equal
We can prove the given expression, sin(x + y) ≠ sin x + sin y by taking the value of x and y as 90 respectively.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between the sides and angles of a right-angle triangle. The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
It is given that the expression is"sin(x + y) sin(x+y)
Suppose, x=0 and y=90
We have to prove the following expression,
sin(x + y) ≠ sin x + sin y
Left-hand side,
=sin(x + y)
=sin(90+90)
=sin 180
=0
Right-hand side,
=sin x + sin y
=sin90+sin90
=1+1
=2
As a result,
sin(x + y) ≠ sin x + sin y
Thus, we can prove the given expression, sin(x + y) ≠ sin x + sin y by taking the value of x and y as 90 respectively.

Which one of the points satisfies the following two linear constraints simultaneously?
2x + 5y ≤ 10 10x + 6y≤ 42
a. x= 6, y = 2
b. x=6, y = 4
c. x=2, y = 1
d. x=2, y = 6
e. x = 5, y = 0
The point e. x = 5, y = 0 satisfies the two linear constraints simultaneously. We have two linear constraints which are given as;
2x + 5y ≤ 10 (Equation 1)
10x + 6y ≤ 42 (Equation 2)
We need to find the point which satisfies both equations. Let us plug in the values one by one to check which one satisfies the two equations simultaneously.
a. x= 6, y = 2
In Equation 1:2x + 5y = 2(6) + 5(2) = 17
In Equation 2:10x + 6y = 10(6) + 6(2) = 66
Thus, this point does not satisfy equations 1 and 2 simultaneously.
b. x=6, y=4
In Equation 1:2x + 5y = 2(6) + 5(4) = 28
In Equation 2:10x + 6y = 10(6) + 6(4) = 72
Thus, this point does not satisfy equations 1 and 2 simultaneously.
c. x=2, y = 1
In Equation 1:2x + 5y = 2(2) + 5(1) = 9
In Equation 2:10x + 6y = 10(2) + 6(1) = 26
Thus, this point does not satisfy equations 1 and 2 simultaneously.
d. x=2, y = 6
In Equation 1:2x + 5y = 2(2) + 5(6) = 32
In Equation 2:10x + 6y = 10(2) + 6(6) = 52
Thus, this point does not satisfy equations 1 and 2 simultaneously.
e. x = 5, y = 0
In Equation 1:2x + 5y = 2(5) + 5(0) = 10
In Equation 2:10x + 6y = 10(5) + 6(0) = 50
Thus, this point satisfies both equations simultaneously.

What is the slope of 1.5x+4.5y=18 ,and how do you know?
Answer:
m=-1/3
Step-by-step explanation:
The slope of this line is m=-1/3 because if you use the slope-intercept formula, y=mx+b, m is the slope. If you take this equation and plot two points on a line that has this equation, the slope will be negative if the line forms an obtuse angle on the 0 line. In this case, m=-1/3 as the line goes back 1/3 unit for every unit in this equation. Hope it helps!
Answer: the slope is -0.33... The does means that 3 is repeating.
Step-by-step explanation:
First we will convert the equation into slope intercept form, which is the same way of solving for y in the equation.
1.5x + 4.5y = 18 Solve for y by first subtracting 1.5x from both sides
-1.5x -1.5x
4.5y = 18 - 1.5x Now divide both sides by 4.5
y= 4- 0.33x
y= -0.33x + 4 Now the slope is the coefficient of the variable x which is the number that comes after the variable.
In this case, the slope is -0.33...
The probability of a randomly selected adult having a rare disease for which a diagnostic test has been developed is 0.002. The diagnostic test is not perfect. The probability the test will be positive (indicating that the person has the disease) is 0.96 for a person with the disease and 0.01 for a person without the disease. The proportion of adults for which the test would be positive is
The probability of contracting an illness is 0.0475.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.The likelihood that an event will occur increases with its probability.A straightforward illustration is tossing a fair (impartial) coin.The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is .According to our question-
D: The patient has the illness
ND: the individual without the disease
TD: The results of the test show the patient has the illness.
P(D) will therefore equal 0.001 since only 0.001 of the population is affected by the disease.
P(ND) = 0.991
Because the test successfully identifies a patient with the condition 99% of the time, P(TD/D) = 0.99.
P(TD/ND) = 0.02 because the test indicates that a healthy person contracts the disease 2% of the time.
We are seeking for P(D|TD) and P(ND|TD), respectively.
According to the Bayes formula, 0.00099/0.00099+0.01982 = 0.00099/0.02081 = 0.0475 = (0.99*0.001)/(0.99*0.001)+(0.02*0.991)
And, \s = 1 - \s = 1 - 0.0475 \s = 0.9525
Therefore,
The likelihood of having an illness is 0.0475.
The likelihood of not having any sick people is 0.9525.
Hence, The probability of contracting an illness is 0.0475.

A firm experiences_______ if inputs are doubled and output more than doubles. diminishing marginal rate of technical substitution diminishing marginal product decreasing returns to scale increasing returns to scale
A firm experiences increasing returns to scale if inputs are doubled and output more than doubles.
When the firm's output grows at a faster rate than the growth in inputs, increasing returns to scale result. In this case, the company experiences economies of scale, which makes it more effective as it grows its production.
The firm is able to boost productivity and efficiency as it expands its scale of operations if inputs are doubled and output more than doubles.
This can be ascribed to a number of things, including specialisation, labour division, the use of capital-intensive technology, discounts for bulk purchases, and spreading fixed costs over a higher output. Lower average costs per unit of output result in higher profitability and competitiveness for the company.
The firm gains a number of benefits from growing returns to scale. First off, it lets the company to benefit from cost savings brought about by economies of scale, allowing it to manufacture goods or services for less money per unit. This may enable more competitive pricing on the market or result in larger profit margins.

What is the slope of the line perpendicular to y 1 4x 10?
The slope of the line perpendicular to the given line is equal to -4/1.
The equation is in the form y=mx+b
so, y=(1/4)x -10
First, find the slope of the line which is the value being multiplied by x. Therefore m=1/4
To find the slope perpendicular to the line you must find the negative reciprocal of 1/4. (Which just means change the sign then flip the fraction)
Multiplying 1/4 by -1 which is -1/4
Then flip the fraction and keep the sign with the numerator to find the reciprocal. So now it’s -4/1

7. Write the correct tangent equation to solve for angle F.
Picture Below
The value of tan F in this right-angled triangle is approximately 3.42857.
In the right-angled triangle DEF, with a right angle at E, we are given the length of the perpendicular DE, which is 24 cm, and the length of the base EF, which is 7 cm.
To find the value of tan F, we can use the tangent function, which is defined as the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.
In this case, F is the angle opposite to side DE, and the adjacent side is EF. So, we can write:
tan F = DE / EF
Substituting the given values, we have:
tan F = 24 cm / 7 cm
Now, we can divide 24 by 7:
tan F ≈ 3.42857
So, the value of tan F in this right-angled triangle is approximately 3.42857.
This means that the ratio of the length of the perpendicular side DE to the length of the base side EF is approximately 3.42857. It indicates how steep or inclined the line EF is with respect to the line DE in the triangle DEF.
Remember that tangent is a trigonometric function that relates the angles of a right triangle to the lengths of its sides. In this case, we used it to find the ratio of the sides in the triangle and determine the value of tan F.

what inferences about the relation between income and type of oven usage in population may be drawn from the data above?
No inferences can be made without performing a hypothesis test
A hypothesis test is a statistical test used to determine whether a specific hypothesis about a population parameter is supported by the data. In this test, a null hypothesis (H0) is stated, which is usually the assumption that the population parameter is equal to a specific value or falls within a certain range. An alternative hypothesis (Ha) is also stated, which is usually the opposite of the null hypothesis.
The next step is to collect data and use statistical techniques to calculate a test statistic, which measures how far the sample data deviates from the null hypothesis. The test statistic is compared to a critical value in a probability distribution, such as a t-distribution or z-distribution, which is determined based on the level of significance (alpha) and the degrees of freedom

Answer:
x = 77, y = 63
Step-by-step explanation:
x - 5 = 72 ( corresponding angles )
x = 77
The 3 angles on the straight line sum to 180°, that is
x - 5 + 51 + y - 6 = 180, that is
72 + 51 + y - 6 = 180
117 + y = 180 ( subtract 117 from both sides )
y = 63
Determine the equation of the line that passes through (-8,9) and (2,-6)
Express you answer as a fraction in lowest terms.
The equation of the line that passes through the points (-8, 9) and (2, -6) is y = (-3 / 2)x - 3.Given two points (-8, 9) and (2, -6). We are supposed to find the equation of the line that passes through these two points.
We can find the equation of a line that passes through two given points, using the slope-intercept form of the equation of a line. The slope-intercept form of the equation of a line is given by, y = mx + b,Where m is the slope of the line and b is the y-intercept.To find the slope of the line passing through the given points, we can use the slope formula: m = (y2 - y1) / (x2 - x1).Here, x1 = -8, y1 = 9, x2 = 2 and y2 = -6.
Hence, we can substitute these values to find the slope.m = (-6 - 9) / (2 - (-8))m = (-6 - 9) / (2 + 8)m = -15 / 10m = -3 / 2Hence, the slope of the line passing through the points (-8, 9) and (2, -6) is -3 / 2.
Now, using the point-slope form of the equation of a line, we can find the equation of the line that passes through the point (-8, 9) and has a slope of -3 / 2.
The point-slope form of the equation of a line is given by,y - y1 = m(x - x1)Here, x1 = -8, y1 = 9 and m = -3 / 2.
Hence, we can substitute these values to find the equation of the line.y - 9 = (-3 / 2)(x - (-8))y - 9 = (-3 / 2)(x + 8)y - 9 = (-3 / 2)x - 12y = (-3 / 2)x - 12 + 9y = (-3 / 2)x - 3.
Therefore, the equation of the line that passes through the points (-8, 9) and (2, -6) is y = (-3 / 2)x - 3. Thus, the answer is (-3/2)x - 3.
