Answer:

The answer is B) 1/25

Step-by-step explanation:

This is because given that f(x) = 5^x

Hence, f(-2) would be 5^-2, which is equal to (1/5^2) => 1/25

Because a^-b can be written as 1/a^b

The Midline is the middle of the number of the function.

The Amplitude is from the midline to the highest or lowest point of the function.

The period is the distance on the x axis from the two points.

Hope this helps!

Geometric Sequence:1/2,1/3,2/9,4/27,8/? I don't know the bottom number but the top number is 8☹️

Aleks [24]

Hello,

In this geometric sequence, the ratio is (1/3)/(1/2)=(1*2)/(3*1)=2/3

1/2*2/3=2/6=1/3
1/3*2/3=2/9
2/9*2/3=4/27
4/27*2/3=8/81

Write the equation of a circle with center (-2, 0) and area = 64 pi

kozerog [31]

Answer:

The required equation in standard form is $(x+2)^2+y^2=64$

Step-by-step explanation:

The equation of a circle with center (h,k) an radius, r units is given by the formula;

$(x-h)^2+(y-k)^2=r^2$

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is $64\pi$

$\pi r^2=64\pi$

$\implies r^2=64$

We substitute these values into the formula to obtain;

$(x--2)^2+(y-0)^2=64$

We simplify to get;

$(x+2)^2+y^2=64$
