Hey there! :)

Answer:

D : [-4, ∞)

R: [-2, ∞)

Step-by-step explanation:

Notice that one end of the graphed function has a closed circle, and one end is a line. We must use specific brackets accordingly:

[ is used for closed points.

( is used for arrows or open circles.

Therefore:

This graph goes from x = -4 towards x ⇒∞. Therefore:

D : [-4, ∞)

The range of this function goes from x = -2 towards y⇒ ∞. Therefore:

R: [-2, ∞)

Please answer, i will give 20 points!!!
Lapatulllka [165]

Answer:

36

Step-by-step explanation:

Pentagon has 5 sides

The formula for finding the sum of the measure of the interior angles is (n - 2) * 180

(5-2)×180= 3×180=540

To get each interior angles

540/5 = 108

180 -108 = 72

To get x

72+72+x= 180 (sum if angles in a triangle)

144+x= 180

x = 180 -144 = 36

2. x is part of the interior angles = 108

MakcuM [25]

Answer:

the answer is 80 i think

Step-by-step explanation:

bc dependng on  2lw+2lh+2hw, formula 8 and 10 would be length and width

Lets say

8=width

10=lenght

3in=height

u would do

2 x l x w   + 2 x l h + 2 x h x w=

2 x 10 x 8 + 2 x 10 x 3 + 3 x 8=

160 +            60       +      48+=

268 is the sa

Consider the function f given by f(x)=x*(e^(-x^2)) for all real numbers x.
NISA [10]

Answer:

\frac{\sqrt{\pi}}{4}

Step-by-step explanation:

You are going to integrate the following function:

g(x)=x*f(x)=x*xe^{-x^2}=x^2e^{-x^2}  (1)

furthermore, you know that:

\int_0^{\infty}e^{-x^2}=\frac{\sqrt{\pi}}{2}

lets call to this integral, the integral Io.

for a general form of I you have In:

I_n=\int_0^{\infty}x^ne^{-ax^2}dx

furthermore you use the fact that:

I_n=-\frac{\partial I_{n-2}}{\partial a}

by using this last expression in an iterative way you obtain the following:

\int_0^{\infty}x^{2s}e^{-ax^2}dx=\frac{(2s-1)!!}{2^{s+1}a^s}\sqrt{\frac{\pi}{a}} (2)

with n=2s a even number

for s=1 you have n=2, that is, the function g(x). By using the equation (2) (with a = 1) you finally obtain:

\int_0^{\infty}x^2e^{-x^2}dx=\frac{(2(1)-1)!}{2^{1+1}(1^1)}\sqrt{\pi}=\frac{\sqrt{\pi}}{4}
