Answer:

28,716^3

Step-by-step explanation:

From the given, we need to determine the volume of a sphere. The sphere has a radius of 19 cm.

Calculation,

Sphere Volume = 4/3 * PI * radius^3, is the equation.

Substituting the given values,

Radius = 9 inches, PI = 3.14

volume = 4/3 * 3.14 * 19^3

volume = 28,716.34667 ^3

Therefore, the nearest centimeter is 28,716^3

Answer:

Sphere Volume = (4/3) * PI * radius^3

Volume = (4/3) * PI * 19^3

Volume = 28,730.9120146298

Volume = 28,731 (when using PI = 3.14159265...

Volume = 28,716.3466666667

Volume = 28,716 cc answer is A.

Please help me find the area of this please

frozen [14]

Answer:

117 cm²

Step-by-step explanation:

area of rectangle = 13 * 7 = 91cm²

area of upper one right angle triangle= 1/2 * 6.5 * 4 =13 cm²

area of both triangles = 13 cm² * 2 = 26 cm²

Total area = 91cm² + 26 cm²

--> 117 cm²

Answer: Second Option

$m=0.09$

Step-by-step explanation:

The formula for calculating the average rate of change between two values of x ( $x_1$ and $x_2$ ) is:

$m=\frac{f(x_2)-f(x_1)}{x_2-x_1}$

$f (x_1)$ and $f (x_2)$ are the values of the function when $x = x_1$ and $x = x_2$

In this case

$x_1=3\\x_2=6$

Observe that when $x=3$ , $f(x) =2.41$ and when $x=6$ , $f(x)=2.68$

Finally the average rate of change from 3 to 6 storms is:

$m=\frac{2.68-2.41}{6-3}$

$m=0.09$

When the polynomial P(x)=ax^3+bx^2+3x-10 is divided by x+1, the remainder is -8. P(x) has a factor of x+5. Find the values of a

Ahat [919]

Answer:

a = 1, b = 6

Step-by-step explanation:

The equation given is as follows;

P(x) = a·x³ + b·x² + 3·x - 10

The above equation has a factor of x + 5, therefore, we have;

P(-5) = 0 = a·(-5)³ + b·(-5)² + 3·(-5) - 10

-125·a + 25·b + (-15) - 10 = 0

-125·a + 25·b - 25 = 0

-125·a + 25·b = 25...........(1)

Also, we are given that;

a·x³ + b·x² + 3·x - 10 divided by x + 1 as a remainder, R = -8, therefore;

P(-1) = -8 = a·(-1)³ + b·(-1)² + 3·(-1) - 10

-a + b - 13 = -8

-a + b = -8 + 13 = 5

-a + b = 5............................(2)

Multiply equation (2) by 25 and subtract from (1) gives

-125·a + 25·b - 25(-a + b) = 25 - 25×5

-100·a = 25 - 125 = -100

a = 1

Therefore, from equation (2) we have;

-1 + b = 5

b = 5 + 1 = 6.
