I don't really know if these are correct because I have never had to define any of those words or know a lot of these. But some of them I am pretty sure are right. I hope I helped some. I am sorry if I didn't. But this is my best guess.

the table below shows the function of f determine the value of f(3) that will lead to an average rate of change of 19 over the i

3241004551 [841]

ANSWER

$f(3) = - 25$

EXPLANATION

We want to determine the value of f(3) that will lead to an average rate of change of 19 over the interval [3, 5].

The average rate of change of f(x) over the interval [a,b]:

$= \frac{f(b) - f(a)}{b - a}$

If the average rate of change over the interval [3, 5] is 19, then;

$\frac{f(5) - f(3)}{5 - 3} = 19$

From the to table f(5)=13

$\frac{13 - f(3)}{2} = 19$

$13 - f(3) = 19 \times 2$

$13 - f(3) = 38$

$- f(3) = 38 - 13$

$- f(3) = 25$

$f(3) = - 25$

A triangle with sides of lengths 9, 22, and 24 is a right triangle

Leona [35]

Answer:

The statement is false

Step-by-step explanation:

we know that

if the triangle is a right triangle

then

the triangle must satisfy the Pythagoras Theorem

$c^{2}=a^{2}+b^{2}$

we have

$c=24\ units$

$a=9\ units$

$b=22\ units$

substitute

$24^{2}=9^{2}+22^{2}$

$576=81+484$

$576 \neq 565$

therefore

Is not a right triangle

The statement is false

What is the area of the trapezoid shown? trapezoid A = ______ units²?

notka56 [123]

Answer:

74.1 units²

Step-by-step explanation:

Area of the trapezoid shown = ½×(AD + BC)×BE

Use distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ to find AD, BC, and BE.

✍️Distance between A(-9, 4) and D(9, 1):

$AD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(9 -(-9))^2 + (1 - 4)^2}$

$= \sqrt{(18)^2 + (-3)^2}$

$= \sqrt{(324 + 9} = \sqrt{333}$

$AD = 18.2 units$ (nearest tenth)

✍️Distance between B(-4, -3) and C(2, -4):

$BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(2 -(-4))^2 + (-4 -(-3))^2}$

$= \sqrt{(6)^2 + (-1)^2}$

$= \sqrt{(36 + 1} = \sqrt{37}$

$BC = 6.1 units$ (nearest tenth)

✍️Distance between B(-4, -3) and E(-3, 3):

$BE = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(-3 -(-4))^2 + (3 -(-3))^2}$

$= \sqrt{(1)^2 + (6)^2}$

$= \sqrt{(1 + 36} = \sqrt{37}$

$BE = 6.1 units$ (nearest tenth)

✔️Area of the trapezoid:

Area = ½×(AD + BC)×BE

Plug in the values into the formula

Area = ½×(18.2 + 6.1)×6.1

Area = ½×(24.3)×6.1

Area = 74.115 ≈ 74.1 units² (nearest tenth)
