Answer 2

Answer:

a. 18 b. 15/64 c. 122 2/9 d. 157.5615 e. 19.8

Step-by-step explanation:

b. multiply across, so 1 * 15 = 15, 4*16=64, 15/64 can't be reduced, so done

c. 13 3/4 * 7 8/9, you must convert to improper fractions to multiply

4*13+3 = 55 so the first part is 55/4, 7*9+8=80 so the second is 80/9

55/4 * 80/9 = (55*80) / (4*9) = 4400 / 36, both are divisible by 4 so can be reduced to 1100/9 which cannot be reduced any further, 1100 + 9 = 122 R 2 so

1100/9 = 122 2/9

d. used calculator

e. 33% of 60 = (33//100)*(60/1) = (33*60) / (100*1) = 1980 / 100 = 19.8

Find the gradient of the line segment between the points (-6,2) and (4,3).
Give your answer in its simplest form.

Answers

Gradient = 0.1

Step-by-step explanation:

ΔX = 4 – -6 = 10

ΔY = 3 – 2 = 1

Gradient = m = ΔY/ ΔX = 1/10 = 0.1

The gradient of a line segment is a measure of how steep the line is. A line with a large gradient will be steep; a line with a small gradient will be relatively shallow; and a line with zero gradient will be horizontal.

The answer is 7. It is decreasing by 7 each time.

Answer

GCF is 1 and the x is

Multiples of 7 are: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, ... A common multiple is a whole number that is a shared multiple of each set of numbers. The multiples that are common to two or more numbers are called the common multiples of those numbers.

The equation of line AB is y = 2x + 4. Write an equation of a line parallel to line AB in slope-intercept form that contains point (3, 1). (3 points)

According to Synthetic division below, which of the following statements are true

Answers

Answer:

B, E, and F.

Step-by-step explanation:

We can apply synthetic division when dividing a polynomial P(x) by a binomial in the form (x - a).

Looking at the coefficients, we can see that our dividend is:

[tex]3x^2-11x+10[/tex]

Our divisor will be (x - a), where a is the number on the very top left.

So, a = 2.

Thus, our divisor is:

[tex](x-2)[/tex]

Note that our remainder is 0.

So, the synthetic division shown is telling us that:

[tex]( 3x^2 - 11x + 10) \div (x-2) = 3x - 5[/tex]

Hence, E is the correct choice. A uses the incorrect divisor.

If the divisor successfully divides with no remainder, then the divisor is a factor.

Since (x - 2) successfully divided with no remainder, (x - 2) is indeed a factor of the polynomial.

Hence, B is also correct.

C uses the wrong factor.

D uses the wrong value. It should be positive 2.

So, F is the correct choice.

Therefore, the answers are: B, E, and F.

5. What is the value of x to the nearest tenth? The figure is not drawn to scale.

Answers

Answer:

5.46

Step-by-step explanation:

Using pythagoras theorem;

AD^2 = 5.3^2 - 4.1^2

AD^2 = 28.09-16.81

AD^2 = 11.28

AD = √11.28

AD = 3.36

x^2 = 3.36^2+4.3^2

x^2 = 11.28 + 18.49

x^2 = 29.77

x = 5.46

Hence the value of x is 5.46

Evaluate the expression for the given value of x.
5x + 6 for x = 4

Answers

If x=4, rewrite the equation which would be 5(4)+6

First you multiply 4 by 5 which would give you 20

Now put in the 6 in the equation

20+6

20+6=26

Therefore for the expression given the value of x would make your answer be 26

Does the point (–84, –82) satisfy the equation y = x + 2?

Answers

Answer:

It does satisfy the equation y=x+2

Step-by-step explanation:

To find if it satisfy the equation y=x+2 is by subsituting x with -84 and y with -82

-82=-84+2

2-84= -82

-82=-82 which is true so it satisfy the equation

Rule: Multiply by 1.04

b. To the nearest dollar, how much will Sarah make year 5?

c. During what year will Sarah first make more than $40,000 per year?

Answers

Answer:

a) P(x) = 32000*1.04^xb) $37435c) During year 7

Step-by-step explanation:

Given

Initial pay = $32000Increase rate = 4%

a. Formula

P(x) = 32000*1.04^x

b. Year 5 is after 4 years, so we are looking for the value of P(4)

P(4) = $32000*1.04^4 = $37435

c. P(x) = 40000, x = ?

40000 = 32000*1.04^x1.04^x = 40000/320001.04^x = 1.25log 1.04^x = log 1.25x = log 1.25 / log 1.04x = 5.69, this is 6 years after
