Answer:

The factored form is:

4(5v + 9)(5v - 9)

Step-by-step explanation:

The given expression is:

100 {v}^{2}  - 324

The Greatest Common Factor is 4:

We factor the GCF to get

4(25 {v}^{2}  - 81)

We rewrite the expression within the parenthesis as difference of two squares.

4(( {5v})^{2}  -  {9}^{2} )

Recall that: a²-b²=(a-b)(a+b)

This implies that

4(5v + 9)(5v - 9)

How do I solve this question?

Answer:

n=2.5

Step-by-step explanation:

First, write an equation!

n+5n-6+2n+1=15

Now, combine like terms to make things easier.

8n-5=15

Cancel -5 from the left to isolate 5n as a variable.

8n-5+5=15+5

8n=20

Now divide both sides by 8.

8n/8=20/8

n=2.5

Given P equals $11260, T equals six years, and R equals 7.5% compounded weekly. Use the correct compound interest formula to cal
Dmitrij [34]

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

where

A = total amount in the account at the end of t years

r represents the interest rate

n represents the periodic interval at which it was compounded

p represents the principal or initial amount deposited

From the information given,

P = 11260

t = 6

r = 7.5/100 = 0.075

n = 52(Assuming the number of weeks in a year is 52 and it would be compounded 52 times in a year)

Thus, we have

A = 11260(1 + 0.075/52)^52*6

A = 11260(1 + 0.075/52)^312

A = 17653.5

A boat took 5 h to travel 60 km up a river, against the current. The return trip took 3 h. Find the speed of the boat in still w
Dafna11 [192]

Answer:

Correct answer: V₁ boat = 16 km/h and V₂ current = 4 km/h

Step-by-step explanation:

If we take speed (velocity) of the boat as V₁ and speed of the current V₂

Let us form equations:

Traveling down the current  V₁ + V₂ = 60/3 = 20 km/h

Traveling against the current  V₁ - V₂ = 60/5 = 12 km/h

V₁ - V₂ = 12

V₁ + V₂ = 20

If we add up the left and right sides of the equations we get:

2 V₁ = 32  =>    V₁ = 32/2 = 16 km/h

from the second equation we get:

V₂ = 20 - V₁ = 20 - 16 = 4 km/h

V₂ = 4 km/h
