Answer:

$7$

Step-by-step explanation:

Because the leftmost triangle is a 45-45-90 isosceles right triangle, $a = b =\frac{7\sqrt2}{\sqrt2} = 7\\$

The rightmost triangle is a 30-60-90 triangle, and the side lengths are in the proportion $1:\sqrt3:2$ from shortest to longest. Therefore, $c = 7\cdot\frac{\sqrt3}{1} = 7\sqrt{3} \implies \boxed{7}$

A player shoots a basketball from a height of 6 feet. The equation, h = -16t^2 + 25t + 6, gives the height, h , of the basketbal

noname [10]

Answer:

$\boxed {\boxed {\sf 7.5 \ feet}}$

Step-by-step explanation:

We are given this function for the height (h) after t seconds:

$h=-16t^2+25t+6$

Seconds is t and we want to find the height after 1.5 seconds. Plug 1.5 in for t.

$h= -16(1.5)^2+25(1.5)+6$

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Solve the exponent first.

(1.5)²= 1.5*1.5=2.25

$h= -16(2.25)+25(1.5)+6$

Multiply.

$h= -36+25(1.5)+6$

$h= -36+37.5+6$

Add.

$h=1.5+6=7.5$

This is already rounded to the nearest tenth, so it is the answer.

After 1.5 seconds, the basketball is at a height of 7.5 feet.

Find the area of the kite. Hint: The brackets indicates the full length of a segment

xxMikexx [17]

Answer: 54 ft²

Step-by-step explanation:

Area of a kite is calculated by the formula:

= (Length * Height) / 2

Length = 6 + 6 = 12 ft

Height = 9 ft

Area = (12 * 9) / 2

= 108 / 2

= 54 ft²
