Step-by-step explanation:

The formula of an area of a triangle is:

area = height × width ÷ 2

We can put in the values of the area and width first.

20 = height × 10 ÷ 2

20 = height × 5

Shift the (×5) to the left-hand side of the equation, making it (÷5).

20 ÷ 5 = height

height = 4

Answer:

A=1/2b×h

we have,

b=10 cm

A=20cm2

1/2b×h=20cm2

1/210×h=20

5h=20

h=4cm

Answer:

Step-by-step explanation:

The area of a rectangle is length time width.

A=LW

In this case,

A=32x^2+12

W=4x

Solve for L

L=A/W

Substitute

L=(32x^2+12)/4x

L=(8x^2+3)/x

Step-by-step explanation:

focus of the parabola is (2,0) and directrix is x=-2. Here,a=2.So, Equation becomes, y2=4∗2x⇒y2=8x, which is the required equation of parabola.

The equation of a parabola with the given focus and directrix is x²-10x+74=14y.

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line

Given that, a parabola has focus (5,7) and directrix y=0.

When the focus (h, k) of a parabola and the equation of the directrix y = c are given, the equation of the parabola is given by (x-h)²+k²-c²=2(k-c)y

Here, y=c=0

Now, (x-5)²+7²-0²=2(7-0)y

x²-10x+25+49=14y

x²-10x+74=14y

Therefore, the equation of a parabola is x²-10x+74=14y.

The function y = - 50x + 75 is linear. So, the correct option is (A).

The formula for a linear function is f(x) = mx + b, where m and b are real values. Isn't it resembling the slope-intercept form of a line, represented by the equation y = mx + b? Yes, this is the case as the graph of a linear function is a line. Here,

The line has a slope of m and a y-intercept of b.

The independent variable is "x."

The dependent variable is "y" (also known as f(x)).

Consider the equation y = - 50x + 75

Compared to the linear function equation, we get

m = -50

b = 75

Step-by-step explanation:

The area of a triangle is equivalent to its length multiplied by its width.

In this example, one way we can look at this is to make everything in terms of two. First, we know that

\(2^{4} = 16\\\sqrt[5]{2^{4}} = \sqrt[5]{16} \\2^{4 (1/5)} = \sqrt[5]{2^{4}}\)

We can establish that last line because x^((y)^(z)) = x^(y*z), as is stated in exponent rules. Therefore, our area is

\(2^{4/5} * 2^{1/5} = 2^{4/5 + 1/5} = 2^{5/5} = 2^{1} =2\)

10.59 is the value of the given side b.

In our case, we know that side A has a length of 15 units and is opposite angle A, which measures 27 degrees.

Using the sine rule, we can write:

b/sin(27°) = 15/sin(40°)

To find the value of b, we can rearrange the equation:

b = (15 * sin(27°)) / sin(40°)

evaluate the trigonometric functions and calculate b:

b ≈ 10.59

Therefore, using the sine rule of the triangle, we find that the value of side b is approximately 10.59 units.

Answer:

Step-by-step explanation:

Okay, so assuming you have set up your division problem, you first have to find a value that will set x = to x^3. This value is x^2. So, put that above the division symbol. Next, multiply (x +4) by x^2. Then, subtract that answer from x^3 + x^2. You should get -3x^2 - 10x. Then, find a value to get x to -x^2. This value is -3x. So, put that above the division symbol. Multiply (x + 4) by -3x. Then, subtract that value from -3x^2 - 10x. You should get 2x + 8 as your answer. Now find a value to get x to 2x. 2 should work. So, put that above the division symbol.  Multiply (x +4) by 2. When subtract your answer from 2x + 8 you get 0. Therefore, the answer is x^2 - 3x +2. Hope this helps!!

Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

--------------------------------------------------------

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

The area of shape is the space enclosed within the perimeter or the boundary of a given shape. Area is measured in units².

The shape above can be divided into 4 shapes.

The area of the first triangle = 1/2 bh

Answer:

No, the solution is -3.

Step-by-step explanation:

3y+10=-5y-14

We move all terms to the left:

3y+10-(-5y-14)=0

We get rid of parentheses

3y+5y+14+10=0

We add all the numbers together, and all the variables

8y+24=0

We move all terms containing y to the left, all other terms to the right

8y=-24

y=-24/8

y=-3

Answer:

y = - 3

Step-by-step explanation:

3y + 10 = - 5y - 14 ( add 5y to both sides )

8y + 10 = - 14 ( subtract 10 from both sides )

8y = - 24 ( divide both sides by 8 )

y = - 3

Let Dad = Y, Son = X

Mathematically, from your statement:

Y = 3X, and (Y+10) + (X+10) = 68

Solving for X in 2nd equation, X = 48-Y

Insert this into first equation and solve for Y:

Y = 3(48-Y)

Y= 144 - 3Y

The answer of 32+28x+3x²​ is (x+3)(3x+4).It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" for the absolute term of f. (x).

The quadratic equation is known as a "univariate" equation since there is only one unknown in it. The quadratic equation is a polynomial equation because all of the powers of x that it contains are non-negative integers. Given that the largest power is two, the equation is a second degree polynomial.

To determine quadratic equation, we obtain,

32+28x+3x²​=0

x=-28±\(\sqrt{28^{2} ​-4x3x32}\)/2×3

⇒x=\(\frac{-28±20}{2x3}\)

x=-\(\frac{8}{6}\) =-\(\frac{4}{3}\)

and, x=\(\frac{-48}{6}\)=-8

so, x = -\(\frac{4}{3}\) or -8.

32+28x+3x²​= a(x-\(x_{1}\))(x-\(x_{2}\))

The confusion earlier.

Given the information that Triangle ABC has a perimeter of 40 inches, we can proceed to find the length of AC.

Let's assume that AC has a length of x inches.

Since the perimeter of a triangle is the sum of the lengths of its sides, we can set up an equation:

AC + AB + BC = 40

Substituting the values in the equation, we have:

x + AB + BC = 40

Without any additional information or specific lengths for AB and BC, it is not possible to determine the exact value of x or AC.

The lengths of AB and BC could vary, resulting in different values for AC.

the prior haziness.

We can go on to find the length of AC now that we know Triangle ABC has a perimeter of 40 inches.

Assume for the moment that AC is x inches long.

We may create the equation AC + AB + BC = 40 since the perimeter of a triangle is equal to the sum of the lengths of its sides.

With the variables in the equation substituted, we get x + AB + BC = 40.

The exact value of x or AC cannot be calculated in the absence of any more details or precise lengths for AB and BC.
