If P(x) = 25x² - 24x + 615
Then, when x = 8:
P(x) = P(8)
= 25(8)² - 24(8) + 615
= 1600 - 192 + 615
= 2023

Answer:

2023 is answer

Step-by-step explanation:

P(x)= $25x^2-24x+615$

for x =8 ,we get the value

P(8)= $25(8)^2-24(8)+615$

=1600-192+615

=2023

The average value of a function f over the interval [−2,3] is −6 , and the average value of f over the interval [3,5] is 20. Wha

Xelga [282]

Answer:

The average value of $f$ over the interval $[-2,5]$ is $\frac{10}{7}$ .

Step-by-step explanation:

Let suppose that function $f$ is continuous and integrable in the given intervals, by integral definition of average we have that:

$\frac{1}{3-(-2)} \int\limits^{3}_{-2} {f(x)} \, dx = -6$ (1)

$\frac{1}{5-3} \int\limits^{5}_{3} {f(x)} \, dx = 20$ (2)

By Fundamental Theorems of Calculus we expand both expressions:

$\frac{F(3)-F(-2)}{3-(-2)} = -6$

$F(3) - F(-2) = -30$ (1b)

$\frac{F(5)-F(3)}{5-3} = 20$

$F(5) - F(3) = 40$ (2b)

We obtain the average value of $f$ over the interval $[-2, 5]$ by algebraic handling:

$F(5) - F(3) +[F(3)-F(-2)] = 40 + (-30)$

$F(5) - F(-2) = 10$

$\frac{F(5)-F(-2)}{5-(-2)} = \frac{10}{5-(-2)}$

$\bar f = \frac{10}{7}$

The average value of $f$ over the interval $[-2,5]$ is $\frac{10}{7}$ .

I don’t understand this question?

Andrej [43]

Answer:

no, because it has a constant rate of change

Step-by-step explanation:

this is because the x and y change at the same rate. non linear means that they dont change at the same rate.

mike says 3/3 of his fraction model is shaded blue. Ryan says 6/6 of the same model is shaded blue . are the two fractions equiv

Jet001 [13]

Yes, they are equivalent. Another equivalent fraction would be any fraction that equals to 1. Eg. 9/9

What is the answer to: 20*5 thank you very much

Digiron [165]

20 times 5 is 100. We can multiply 2*5 and get 10, then add another zero to make it easier.

Step-by-step explanation:

<u>Congruent Triangles</u>

The figure shows two triangles FCD and FED. One of their sides is the radius of the circle, they both form a 90° angle with the line CD and ED and they share the same segment FD.

Thus, both triangles are congruent and we have the length of a side (12 units), one common side (the hypotenuse) and one unknown leg that must be equal. Therefore

$13x-16=4x+11$
