area of trapezoid with dimensions $b_1 = 4\frac{1}{4} , b_2 = 3\frac{3}{4}, h = 2\frac{1}{2}$ is $Area =10in^2$ .

<u>Step-by-step explanation:</u>

We know that area of trapezoid is , area = $(\frac{a+b}{2} )h$ , where a & b are bases and h is height . We have , $b_1 = 4\frac{1}{4} , b_2 = 3\frac{3}{4}, h = 2\frac{1}{2}$ .

Area = $(\frac{a+b}{2} )h$

⇒ $Area = (\frac{a+b}{2} )h$

⇒ $Area = (\frac{b_1+b_2}{2} )h$

⇒ $Area = (\frac{4\frac{1}{4} +3\frac{3}{4}}{2} )(2\frac{1}{2} )$

⇒ $Area = (\frac{\frac{17}{4} +\frac{15}{4}}{2} )(\frac{5}{2} )$

⇒ $Area = (\frac{\frac{17+15}{4}}{2} )(\frac{5}{2} )$

⇒ $Area = (\frac{\frac{32}{4}}{2} )(\frac{5}{2} )$

⇒ $Area = (\frac{8}{2} )(\frac{5}{2} )$

⇒ $Area = (\frac{40}{4} )$

⇒ $Area =10in^2$

Therefore, area of trapezoid with dimensions $b_1 = 4\frac{1}{4} , b_2 = 3\frac{3}{4}, h = 2\frac{1}{2}$ is $Area =10in^2$ .

The function p(x) = - 2(x-9)2 + 100 is used to determines the profit on T-shirts sold for x dollars. What would the profit from

dolphi86 [110]

ANSWER

$28

EXPLANATION

The profit function is given as:

$p(x) = - 2 {(x - 9)}^{2} + 100$

where x is the price of the T-shirt in dollars.

To find the profit on a T-shirt whose price is $15, we substitute x=15 into the function and simplify.

$p(15) = - 2 {(15 - 9)}^{2} + 100$

We simplify to get:

$p(15) = - 2 {(6)}^{2} + 100$

$p(15) = -72+ 100$

$p(15) = 28$

The sum of the angle measures of a polygon with n sides is 18001800. find n.

Contact [7]

Using
(n-2)180 = 18001800
(n-2) = 18001800÷180
n-2 = 100010
n = 100010+2
n= 100012 sides
