Answer:

5(v-5)(v+4)

Step-by-step explanation:

We have given a expression.

5v²-5v-100

We have to calculate the factor of given expression.

As we know that 5 is multiple of 5 and 100.

taking 5 common from given expression, we have

5(v²-v-20)

Splitting the middle term of given expression, we have

5(v²-5v+4v-20)

Making groups and taking common, we have

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

Taking v-5 as common, we have

5(v-5)(v+4) which is the answer.

5 {v }^{2}  - 5v - 100 \\  = 5( {v}^{2}  - v - 25) \\  = 5({v}^{2}   + 4v - 5v - 20) \\  = 5[v(v + 4) - 5(v + 4)] \\  = 5(v - 5)(v + 4)

What lump sum do parents need to deposit in an account earning 9%, compounded monthly, so that it will grow to $100,000 for thei
gogolik [260]

Answer:

They need to deposit $31,172.49

Step-by-step explanation:

The compound interest formula is given by:

A = P(1 + \frac{r}{n})^{nt}

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time the money is invested or borrowed for, in years.

In this problem

We want to find P for which A = 100000 when r = 0.09, n = 12, t = 13

So

A = P(1 + \frac{r}{n})^{nt}

100000 = P(1 + \frac{0.09}{12})^{12*13}

3.208P = 100000

P = \frac{100000}{3.208}

P = 31172.49

They need to deposit $31,172.49

NEED HELP ASAP!!
storchak [24]

Answer: 1.2 in

Step-by-step explanation:

The pythagorean theorem states that a²+b²=c².  Thus, 0.9²+b²=1.5².

1.5²=2.25

0.9^2=0.81

0.81 + b² = 2.25

1.44 = b²

b = 1.2

Hope it helps <3 :)
