The graphs below have the same shape. f(x)=x2².
tresset_1 [31]

According to the concept of translation, the function of g(x) = x² + 2.

Translation:

The concept of translation is defined by using the function f(x) then f(x + a) is a horizontal translation of f(x)

If the value of a > 0 then a shift to the left of a units

If the value of  a < 0 then a shift to the right of a units

Given,

Here we have the function f(x) = x².

Now, we have to find  the equation of the graph of g(x) and how it change in corresponds to f(x).

While we looking the graph, the function f(x) has curved on the origin (0, 0).

Where the function g(x)  has curved the point (2,0).

Which tells the the graph is move left side by 2 units.

So, according to the rule of translation, the value of a is 2.

Then the function g(x) is written as,

=> g(x) = x² + 2.

What is the volume of the figure in terms of pi?
photoshop1234 [79]

Answer:

1539.38

Step-by-step explanation:

this can be figured out as an entire cylinder and then take 1/2 of that

area of a circle of 7 cm

area = \pi7^{2}

area = 153.938

volume = 153.938 * 20

volume = 3078.7608

and take 1/2 of that to find volume of the half cylinder

3078.7608 / 2 = 1539.38

A soccer ball was kicked in the air and follows the path h(x)=−2x2+1x+6, where x is the time in seconds and h is the height of t
faust18 [17]

Answer:

x= 2 seconds

Step-by-step explanation:

Hello, I can help you with this

Step one

check the data

soccer ball was kicked in the air and follows the path h(x)=−2x2+1x+6

h(x)=−2x2+1x+6,using the correct format

h(x)= -2x^{2} +x+6

where

x is the time in seconds

and

h is the height of the soccer ball

so, when the ball hit the ground its height is o (zero)

you need put this value into the equation and then isolate x to find its value.

Step two

find the value of x, when h=0

h(x)= -2x^{2} +x+6\\0=-2x^{2} +x+6\\using\\x=\frac{-b+\sqrt{ b^{2}-4ac }}{2a}\\ a=-2,b=1,c=6\\x=\frac{-1+\sqrt{ 1^{2}-4(-2)(6) }}{2*-2}\\x=\frac{-1+\sqrt{ 1^{2}+48}}{-4}\\x=\frac{-1+\sqrt{49}}{-4}\\x_{1} =\frac{-1+7}{-4}\\x_{2} =\frac{-1-7}{-4}\\x_{1} =-\frac{3}{2} \\x_{2} =\frac{-8}{-4} \\x_{2}=2

we are looking for a time, so we only are going to use the positive x, it is X2

x= 2 sec

have a good day.

Lena [83]

Answer:

m<B = 141 degrees

Step-by-step explanation:

This shape is a heptagon meaning its angles should have a sum of 900 degrees.

we are given the degrees and we need to ad them up

148+90+120+129+130+142=749

then we subtract 749 from 900 which looks like

900-749=141

from subtracting 749 from 900 we get 141 hence we get our answer that m<B = 141 degrees
