radius ( r) = 1 cm

The volume (V) of a sphere is calculated using the formula

V = $\frac{4}{3}$ πr³

here V is given as V = $\frac{4}{3}$ π

Equating gives

V = $\frac{4}{3}$ πr³ = $\frac{4}{3}$ π

dividing both sides by $\frac{4}{3}$ π, gives

r³ = 1 ( take the cube root of both sides )

r = ∛1 = 1

Ward finances $20,000 to purchase a car. If he gets a 2.5% interest rate regardless of loan length, how much interest will Ward

Radda [10]

You will use the formula to calculate simple interest for each period of time and then subtract the two amounts to find how much Ward will save.

I=prt

I = 20000 x 0.025 x 3

I = $1500 over 3 years

I = 20000 x 0.025 x 5

I = $2500 over 5 years

$2500-$1500 = $1000 in savings

Daniel deposited $500 into a savings account and after 8 years, his investment is worth $807.07. The equation A = d(1.005)12t mo

shtirl [24]

Answer:

Step-by-step explanation:

The equation A = d(1.005)^12t modelling the value of Daniel’s investment shows a monthly compounded interest. This means that the interest is compounded 12 times in a year.

We can confirm by inputting the given values

t = 8 years

d = 509

Therefore,

A = 500(1.005)12 × 8

A = 500(1.005)^96

A = $807.07

Therefore, the true statements are

Increases

Exponential

Never Decrease

What are the solutions to the equation? x^2+6x = 40.

GaryK [48]

Answer:

x = 4, -10

Step-by-step explanation:

Find the zeros of the equations.

Solve the equation:

x^2 + 6x = 40

Subtract -40 from both sides.

x^2 + 6x - 40 = 0

Factor the equation.

(x - 4)(x + 10)

Solve for x with the given information by equaling it to 0.

x - 4 = 0

Add 4 to both sides

x = 4

x + 10 = 0

Subtract 10 from both sides

x = -10

This means that our x values are:

x = 4, -10
