(4,-36)
Step-by-step explanation:
Since the roots of the equation are -2 and 10, you can set up the quadratic like this:
\(y=(x+2)(x-10)\)
Expanded:
\(y=x^2-8x-20\)
To find the x-coordinate of the vertex, use: \(x_{vertex}=\frac{-b}{2a}\)
\(x_{vertex}=\frac{-(-8)}{2(1)}=\frac{8}{2}=4\)
Plug in 4 to either quadratic equation to get the y value:
\((4+2)(4-10)=(6)(-6)=-36\)
Thus the vertex is (4,-36)

Beth earns $3,860 per month. If she saves $579 a month, what percentage of
the salary does she save every month?
Please show how you got this
Answers
The amount that Beth saves as a percentage of her salary is:
$579 / $3,860 * 100% = 14.99%
So, Beth saves approximately 14.99% of her monthly salary every month.
Answer:
15%-----------------------
Divide the amount she saves by her monthly salary and then multiply by 100% to get the percentage.
$579 ÷ $3,860 = 0.15, then 0.15 x 100 = 15%Beth saves 15% of her salary every month.
Centipedes differ from millipedes in that centipedes are cylindrical, have poison claws and 2 pairs of appendages per body segment
Answers
Centipedes differ from millipedes in that centipedes are cylindrical, have poison claws, and 2 pairs of appendages per body segment: FALSE
What are Centipedes?Their bodies have an elongated, cylindrical form that can appear flat at times. Adults can range in size from half an inch to 6.5 inches. Despite its "thousand-legger" moniker, most have less than 100 legs. Despite having so many legs, these arthropods move slowly.Most centipedes can only bite with their poison claws just under the head, causing a bee-like sting; however, Scolopendra can harm a person with the sharp claws of its many walking legs.Centipedes have only one pair of legs on each body segment, which can be seen protruding from their flattened bodies. The number of body segments varies by species, and the number of pairs of legs ranges from 15 to 177, plus or minus one.As it is given in the description, centipedes have only one pair of legs on each body segment. So, the whole statement becomes False.
Therefore, the statement "centipedes differ from millipedes in that centipedes are cylindrical, have poison claws, and 2 pairs of appendages per body segment" is FALSE.

Superior segway tours gives sightseeing tours around chicago, illinois. it charges a one-time fee of $60, plus $28 per hour. what is the slope of this situation? a. 28 b. 32 c. 60d. 88
Answers
Answer:
the answer is (a) 28.
Step-by-step explanation:
The given situation can be represented by a linear equation of the form:
Cost = mx + b
where "m" is the slope (the rate of change of cost with respect to time), "x" is the number of hours of the tour, and "b" is the y-intercept (the cost when x = 0).
In this case, the y-intercept is $60, which represents the one-time fee. The cost increases by $28 per hour, so the slope is:
m = $28/hour
Therefore, the answer is (a) 28.

Which of the following sets of numbers could represent the three sides of a triangle? {6,8,14} {13,20,34} {11,14,22} {13,20,35}
Answers
The set of numbers {6, 8, 14} and the set {11, 14, 22} could represent the three sides of a triangle.
To determine whether a set of numbers could represent the sides of a triangle, we need to check if it satisfies the triangle inequality theorem. According to the theorem, the sum of any two sides of a triangle must be greater than the length of the third side.
Let's evaluate each set of numbers:
1. {6, 8, 14}
The sum of the two smaller sides is 6 + 8 = 14, which is greater than the third side 14. Therefore, this set could represent the sides of a triangle.
2. {13, 20, 34}
The sum of the two smaller sides is 13 + 20 = 33, which is less than the third side 34. Hence, this set cannot represent the sides of a triangle.
3. {11, 14, 22}
The sum of the two smaller sides is 11 + 14 = 25, which is greater than the third side 22. Therefore, this set could represent the sides of a triangle.
4. {13, 20, 35}
The sum of the two smaller sides is 13 + 20 = 33, which is less than the third side 35. Hence, this set cannot represent the sides of a triangle.
In summary, the sets {6, 8, 14} and {11, 14, 22} could represent the three sides of a triangle.

Answers
a) Future value = $11,749.38
Interest = $2,844.82
b) Future value = $11,717.79
Interest = $2,813.23
Explanations:The formula for calculating the future amount (compound amount) is expressed as;
\(\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ \end{gathered}\)P is the amount invested
r is the rate (in decimal)
n is the compounding time
t is the time (in years)
Given the following parameters:
\(\begin{gathered} P=$\$8904.56$ \\ t=7\text{years} \\ n=2(semi-annually) \\ r=4\%=0.04 \end{gathered}\)Substitute the given parameters into the formula:
\(\begin{gathered} A=8904.56(1+\frac{0.04}{2})^{2(7)} \\ A=8904.56(1+0.02)^{14} \\ A=8904.56(1.02)^{14} \\ A=8904.56(1.3195) \\ A\approx\$11,749.38 \end{gathered}\)Hence the future value if the amount invested is compounded semiannually is approximately $11,749.38

Answers
Answer:
m = \(\frac{l}{v-u}\)
Step-by-step explanation:
l = mv-mu (factor out m from mv and mu)
l = m(v-u) - (divide both sides by (v-u))
l/v-u =m
{rewriting it}
i = mv - mu
{factor out the m from the v and u}
i = m(v - u)
{divide both sides by m}
i / m = [m(v - u)] / m
{divide both sides by i}
(i / m) / i = (v - u) / i

A rectangle is inscribed in a parabola y^2 = 16x with the side of the rectangle along the latus rectum of the parabola. If the area of the rectangle is maximized, compute its perimeter.
a. 24.63
b. 13.69
c. 14.57
d. 20.69
Answers
The perimeter of the rectangle, when the area is maximized, is approximately 24.63 units. Therefore, correct option is a.
To maximize the area of the rectangle inscribed in the parabola \(y^2 = 16x\), we need to find the dimensions of the rectangle. Since the side of the rectangle is along the latus rectum of the parabola, we know that the length of the rectangle is equal to the latus rectum.
The latus rectum of the parabola \(y^2 = 16x\) is given by the formula 4a, where "a" is the distance from the focus to the vertex of the parabola. In this case, the focus is located at (4a, 0).
To find "a," we can equate the equation of the parabola to the general equation of a parabola in vertex form: \(y^2 = 4a(x - h)\), where (h, k) is the vertex of the parabola.
Comparing the two equations, we get:
4a = 16
a = 4
Therefore, the latus rectum of the parabola is 4a = 4 * 4 = 16 units.
Since the length of the rectangle is equal to the latus rectum, we have length = 16 units.
Now, to find the width of the rectangle, we need to determine the corresponding y-coordinate on the parabola for the given x-coordinate of the latus rectum. The x-coordinate of the latus rectum is half the length, which is 16/2 = 8 units.
Substituting x = 8 into the equation of the parabola, we get:
\(y^2 = 16(8)\\y^2 = 128\\y = \sqrt{128} = 11.31\)
Therefore, the width of the rectangle is approximately 11.31 units.
The perimeter of the rectangle is given by the formula:
Perimeter = 2(length + width)
Plugging in the values, we have:
Perimeter = 2(16 + 11.31)
Perimeter ≈ 2(27.31)
Perimeter ≈ 54.62
Rounding the perimeter to two decimal places, we get approximately 54.62 units, which is equivalent to 24.63 units.

Given the equation negative 28 equals y over 7, solve for y.
Answers
To solve for y, we need to isolate y on one side of the equation.
We can start by multiplying both sides of the equation by 7, which will cancel out the 7 in the denominator on the left-hand side:
-28 = y/7
-28 * 7 = y
-196 = y
Therefore, y = -196.

AC is a diameter of OE, the area of the

Find BC and mBC.

C
E. plssss hurry !!
Answers
The measure of arc BC is 720 times the measure of angle BAC.
Given that AC is the diameter of the circle and AB is a chord with a length of 16 units, we need to find BC (the length of the other chord) and mBC (the measure of angle BAC).
To find BC, we can use the property of chords in a circle. If two chords intersect within a circle, the products of their segments are equal. In this case, since AB = BC = 16 units, the product of their segments will be:
AB * BC = AC * CE
16 * BC = 2 * r * CE (AC is the diameter, so its length is twice the radius)
Since the area of the circle is given as 289 square units, we can find the radius (r) using the formula for the area of a circle:
Area = π * r^2
289 = π * r^2
r^2 = 289 / π
r = √(289 / π)
Now, we can substitute the known values into the equation for the product of the segments:
16 * BC = 2 * √(289 / π) * CEBC = (√(289 / π) * CE) / 8
To find mBC, we can use the properties of angles in a circle. The angle subtended by an arc at the center of a circle is double the angle subtended by the same arc at any point on the circumference. Since AC is a diameter, angle BAC is a right angle. Therefore, mBC will be half the measure of the arc BC.
mBC = 0.5 * m(arc BC)
To find the measure of the arc BC, we need to find its length. The length of an arc is determined by the ratio of the arc angle to the total angle of the circle (360 degrees). Since mBC is half the arc angle, we can write:
arc BC = (mBC / 0.5) * 360
arc BC = 720 * mBC
Therefore, the length of the arc BC equals 720 times the length of the angle BAC.

Find the equation of a line that passes through (3,-1) and is perpendicular to the equation 3x+y=2
Answers
Answer:
y = (1/3)x - 2
Explanation:
First, we need to identify the slope of the equation 3x + y = 2, so we need to solve for x as:
\(\begin{gathered} 3x+y=2 \\ y=2-3x \end{gathered}\)Now, the number beside the variable x is the slope, so the slope is -3
Then, two lines are perpendicular if the product of both slopes is equal to -1. It means that the slope m for our equation should be:
\(\begin{gathered} -3\cdot m=-1 \\ m=\frac{-1}{-3}=\frac{1}{3} \end{gathered}\)Now, we can find the equation of the line using the following:
\(y=m(x-x_1)+y_1\)Where m is the slope and (x1, y1) is a point on the line. So, replacing my 1/3 and (x1, y1) by (3, -1), we get:
\(\begin{gathered} y=\frac{1}{3}(x-3)+(-1) \\ y=\frac{1}{3}x-\frac{1}{3}\cdot3-1 \\ y=\frac{1}{3}x-1-1 \\ y=\frac{1}{3}x-2 \end{gathered}\)Therefore, the equation of the line is: y = (1/3)x - 2

multiply 1/5 by 3 to get 3/15, and 2/3 by 5 to get 10/15. combined, this is 13/15
