The radius of a circle is 8 kilometers. What is the area?
Scorpion4ik [409]

Answer:

Area of the circle=200.96 km^2

Step-by-step explanation:

Area of a circle=\pi *r*r

For radius(r)=8 km

The area of the circle is :

                 =\pi *8*8

As:    

    \pi =\frac{22}{7}=3.14

Area of the circle:

                        =3.14*8*8\\\\=3.14*64\\\\=200.96km^2

The Area of the circle with the radius of 8km is 200.96 km^2

2. Find the<br> slope of the<br> line between<br> (8, 6) and<br> (20, -14)
Natalka [10]

Answer:

slopee = 5/3

Step-by-step explanation:

The  slope of a line is defined by the rise (the change in y-value) divided by the run (the change in x-value).  Here, the change in y-value is 6 - (-14) = 6 + 14 = 20.  The change in x-value is 20 - 8 = 12.  Therefore, the slope is 20/12 or (simplified) 5/3.

Write 2x + y = 10 in slope intercept form
Viktor [21]
Slope intercept form is y = mx + b.
To convert 2x + y = 10 to slope intercept form, solve for y.
2x + y = 10
y = -2x + 10

Geraldine is asked to explain the limits on the range of an exponential equation using the function f(x) = 2^x. She makes these
Dafna11 [192]

Consider the exponential function f(x)=2^x.

By definition, the domain of a function is the set of input argument values for which the function is real and defined.

Let we take x=2, then f(2)=2^2=4

x=4, then f(4)=2^4=16

x=10, then f(10)=2^{10}=1024

If we chose larger values of x, we get larger function values.

For example, If we take f(0)=2^0=1

f(-3)=2^{-3}=\frac{1}{2^3}=\frac{1}{8}

f(-10)=2^{-10}=\frac{1}{2^10}=\frac{1}{1024}

Thus if we choose smaller and smaller values of x. the f unction values will be smaller and smaller functions.

Thus the domain of the function is the set of all real numbers.

Thus the range is limited to the set of positive real numbers. That is, (0,\infty)

If we choose larger values of x, we will get larger function values, as the function values will be larger powers of 2.

If we choose smaller and smaller x values, the function values will be smaller and smaller fractions.
