What percent of 88 is 72.6? ...?
72.6 is 82.5 percent of 88. To find what percent 72.6 is of 88, divide 72.6 by 88 and then multiply by 100%. This gives you 82.5%, which means 72.6 is 82.5 percent of 88.
Explanation:To find what percent 72.6 is of 88, you can use the formula:
Percentage = (Part / Whole) × 100%
In this case, the 'Part' is 72.6 and the 'Whole' is 88. Plugging these numbers into the formula:
Percentage = (72.6 / 88) × 100%
Percentage = 0.825 × 100%
Percentage = 82.5%
So, 72.6 is 82.5 percent of 88.
Which equation is y = –6x2 + 3x + 2 rewritten in vertex form?
we have
[tex] y = -6x^{2} + 3x + 2 [/tex]
we know that
the vertex form of the vertical parabola equation is equal to
[tex] y=a(x-h)^{2} +k [/tex]
where
(h,k) is the vertex of the parabola
To find the equation rewritten in vertex form let's factor the equation
Factor the leading coefficient
[tex] y = -6(x^{2} - 0.5x) + 2 [/tex]
Complete the square. Remember to balance the equation by adding the same constants to each side
[tex] y = -6(x^{2} - 0.5x+0.0625-0.0625) + 2 [/tex]
[tex] y = -6(x^{2} - 0.5x+0.0625) + 2 +0.375 [/tex]
[tex] y = -6(x^{2} - 0.5x+0.0625) + 2.375 [/tex]
Rewrite as perfect squares
[tex] y = -6(x-0.25)^{2} + 2.375 [/tex]
therefore
the answer is
[tex] y = -6(x-0.25)^{2} + 2.375 [/tex]

graph of parabola going through negative 1, 7 and negative 3, 9.
What is the average rate of change from x = −1 to x = −3?
5
−3
1
−1
Answer:
The correct option is 4. The average rate of change from x = −1 to x = −3 is -1.
Step-by-step explanation:
It is given that the graph of parabola going through (-1,7) and (-3,9).
It means the value of at x=-1 is 7.
[tex]f(-1)=7[/tex]
The value of at x=-3 is 9.
[tex]f(-3)=9[/tex]
The slope of a function f(x) for the interval [a,b] is
[tex]m=\frac{f(b)-f(a)}{b-a}[/tex]
We have to find the average rate of change from x = −1 to x = −3. Here a=-1 and b=-3. So the average rate of change from x = −1 to x = −3 is
[tex]m=\frac{f(-3)-f(-1)}{-3-(-1)}[/tex]
[tex]m=\frac{9-7}{-3+1}[/tex]
[tex]m=\frac{2}{-2}[/tex]
[tex]m=-1[/tex]
The average rate of change from x = −1 to x = −3 is -1. Therefore the correct option is 4.
The length of a rectangle is 6 yards longer than its width. If the perimeter of the rectangle is 32 yd, find its area in square yards.
First, find the width by using the perimeter formula for a rectangle, solve the equation, and then calculate the length by adding 6 yards. With both widths, calculate the area. The rectangle's area is 55 square yards.
Explanation:To solve for the area of the rectangle, we must find its length and width first. The given condition is that the length is 6 yards longer than the width. If we denote the width as w yards, then the length would be w + 6 yards.
Since the perimeter is the sum of all sides, for a rectangle, it can be calculated by the formula P = 2l + 2w, where P is the perimeter, l is the length and w is the width. Substituting the given perimeter (32 yd) and the expressions for length and width, we have:
32 yd = 2(w + 6 yd) + 2w32 yd = 2w + 12 yd + 2w32 yd = 4w + 12 yd32 yd - 12 yd = 4w20 yd = 4ww = 5 yd (width)l = w + 6 yd = 5 yd + 6 yd = 11 yd (length)Now that we have both dimensions, the area of the rectangle can be calculated using the formula A = l × w. Substituting the found values:
Area = 11 yd × 5 yd = 55 yd²
Therefore, the area of the rectangle is 55 square yards.

Find the secant of both angle A and angle B.
A. sec A = 13/5; sec B = 13/12
B. sec A = 13/12; sec B = 13/5
C. sec A = 12/13; sec B = 5/13
D. sec A = 24/10; sec B = 10/24
The secant of angle A is 13/5 and the secant of angle B is 13/12. Option A is correct.
Explanation:To find the secant of angle A and angle B, we need to use the reciprocal function of cosine which is secant. The secant of an angle is equal to the reciprocal of the cosine of that angle.
So, if sec A = 13/5, it means that the cosine of angle A is equal to 5/13. Similarly, if sec B = 13/12, it means that the cosine of angle B is equal to 12/13.
