Answer:

2, 10, 50, 250

Step-by-step explanation:

Using the formula with a₁ = 2 , then

a₂ = 5a₁ = 5 × 2 = 10

a₃ = 5a₂ = 5 × 10 = 50

a₄ = 5a₃ = 5 × 50 = 250

The first 4 terms are 2, 10, 50, 250

If you get $0.75 everyday for 7 years and already have $4.35 (not counting leap years) how much money would you have at the end

Oksanka [162]

Step-by-step explanation:

7 years

leap years in 7 years:- 1

7 minus 1 equals to 6

6 calendar years to days:- 2190 days

so, $0.75 times 2190 = $1642.5

1642.5 plus $4.35 equals to 1646.85

Evaluate the following expression, when n=-3 and r=-8 −5 + 3(−2r + 4n) Pease answer ASAP

Hunter-Best [27]

Answer:

-8

Step-by-step explanation:

Given that,

n = -3

r = -8

Now we have to find the value of the given expression.

For that, you have to replace n and r with ( -3 ) and ( -8 ) respectively.

Let us solve now.

−5 + 3 ( −2r + 4n )

-5 + 3 ( -2 × -8 + 4 × -3 )

-2 ( 16 - 12 )

-2 × 4

-8

Let me know if you've any other questions. :-)

What is BC ? Enter your answer in the box. BC= units

kumpel [21]

Answer:

The length of BC is 25 units.

Step-by-step explanation:

We know that the triangle is an isosceles triangle. Hence, we know that AB = AC. Let's first solve for x.

=> 4x + 1 = 2x + 23
=> 4x - 2x = -1 + 23
=> 2x = 22
=> x = 11

Now, let's substitute the value into the expression.

=> 3x - 8
=> 3(11) - 8
=> 33 - 8
=> 25

Hence, the length of BC is 25 units.

Hoped this helped.
