volume of a sphere = 4/3 *pi * r^3

3/4 * pi = 4/3 *pi * r^3

divide each side by pi

3/4 = 4/3 * r^3

multiply each side by 3/4

3/4 * 3/4 = r^3

9/16 = r^3

take the cube root of each side

r = (9/16) ^ (1/3)

A professional cyclist is training for the Tour de France. What was his average speed in kilometers per hour if he rode the 194

Lisa [10]

Start with the distance equation D=RT, then plug in numbers

194=R x 4.2, so all we have to do is divide 194 by 4.2.

Which of the following options results in a graph that shows exponential growth. F(x) = 0.4(3)^x. F(x) = 3(0.5)^x. F(x) = 0.8(0.

Andre45 [30]

$f(x)=a^x\\\\if\ a \ \textgreater \ 1\ then\ a\ function\ is\ an\ exponential\ growth\ function$

$f(x)=0.4(3)^x\to a=3 > 1\ OK!\\f(x)=3(0.5)^x\to a=0.5 < 1 :(\\f(x)=0.8(0.9)^x\to a=0.9 < 1 :(\\f(x)=0.9(5)^{-x}=0.9\left(\dfrac{1}{5}\right)^x\to a=\dfrac{1}{5} < 1\ :($

Answer: $f(x)=0.4(3)^x$

The width of a rectangle is equal to m cm, but it’s length is five times greater than the width. Find the area of the rectangle.

Irina18 [472]

Area of rectangle is $5m^{2}\ cm^{2}$

Step-by-step explanation:

Given,

Width of rectangle = m cm

As length is 5 times more than width;

Length of rectangle = 5m cm

Area of rectangle = Length x Width

$Area\ of\ rectangle = 5m*m\\Area\ of\ rectangle = 5m^{2} \\As\ length\ and\ width\ both\ are\ in\ cm\,\ therefore\\Area\ of\ rectangle = 5m^{2}\ cm^{2}$

Area of rectangle is $5m^{2}\ cm^{2}$

Explain the difference between finding rational zeros and finding all zeros.

r-ruslan [8.4K]

Answer:

see explanation

Step-by-step explanation:

Given the polynomial

$p(x)=a_nx^n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}+...+a_2x^2+a_1x+a_o$

The rational zeros are all the possible factors of $a_0$ dived by all the possible factors of $a_n$ . Therefore we use the rational rots theorem to find all possible rational zeros.

To find all zeros we use the remainder theorem. Thus, we plug in all the rational zeros to determine which ones evaluate to zero. These are the real zeros. We could also use long division to find the remaining zeros as soon as we got the first zero with the remainder theorem.
