If a math problem asks you about how much something is for division , will the problem make you estimate?
postnew [5]

Answer:

Yes

I hope this answers your question!

Step-by-step explanation:

How do you estimate a division problem?

You can use multiplication to check your division answer this way.

1) Do the division problem.

2) Multiply the quotient times the divisor.

3) If there is a remainder, add it to the multiplication product.

4) Compare this answer to the dividend. They should be the same number (630 = 630).

At the beginning of the year, the number of books owned by a library was 10,000. Since then, it has grown by 1% each month.
aleksklad [387]

Answer:

y = 10(1.01)^60

Step-by-step explanation:

The general equation of exponential growth is

y = ab^x

b has to do with the rate of growth.

b = 1 + r, so in this case, b = 1 + 1% = 1 + 0.01 = 1.01.

Now we have

y = a(1.01)^x

a is the initial value, so now we have

y = 10000(1.01)^x

where y is the number of books after x months

Since you need the number of books after 5 years, we must convert 5 years into months.

5 years * (12 months)/year = 60 months

The problem wants the expression in thousands of books, so we divide the initial value by 1000.

Answer: y = 10(1.01)^60

2. Write an expression to represent f (20)
Furkat [3]

Answer:

I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).

Step-by-step explanation:

So, my answer was f(20) = 64(1/2)^19

f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.

Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19

I hope this helps!

What is the discriminant of 3 x squared minus 10 x = negative 2?
sasho [114]

<u>Answer</u>:

The discriminant of 3 x squared minus 10 x = negative 2 is  76

<u>Explanation</u>:

<u>Given</u>:

3x^2-10x=-2

3x^2-10x+2=0..........(1)

We can find out the discriminant by using the formula

D=b^2-4ac

So from the equation (1)

We have b = -10

a= 3

c= 2

Now put all these values of a,b and c in the formula of discriminant to find out the value of D

So  

D=(-10)^2-4(3)(2)

D=100-24=76

D=76

So the discriminant of the given quadritic equation = 76
