7. Expand and reduce A(x). Then calculate A(x) for x=1.
A (x) = (3x – 3)(3x + 2)

Answers

Given:

The function is

[tex]A(x)=(3x-3)(3x+2)[/tex]

To find:

The simplified form of A(x) and value of A(x) at x=1.

Solution:

We have,

[tex]A(x)=(3x-3)(3x+2)[/tex]

[tex]A(x)=(3x)(3x)+(3x)(2)+(-3)(3x)+(-3)(2)[/tex]

[tex]A(x)=9x^2+6x-9x-6[/tex]

[tex]A(x)=9x^2-3x-6[/tex]

Putting x=1, we get

[tex]A(1)=9(1)^2-3(1)-6[/tex]

[tex]A(1)=9-3-6[/tex]

[tex]A(1)=9-9[/tex]

[tex]A(1)=0[/tex]

Therefore, the simplified form of A(x) is [tex]A(x)=9x^2-3x-6[/tex] and the value of A(x) at x=1 in 0.

Jayla's bank account increased by 7% this year. Write an equation to represent the relationship between the amount that Jayla started with, b, and the amount she has now, c.

Answers

C = b + .07 I think :)))

The equation that represents Jayla's current account balance with the initial amount is c=1.07b.

What is Compound Interest?

Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.

It is given by the formula,

[tex]A = P(1+\dfrac{r}{100})^t[/tex]

where, A is the value after t period of time, and,

r is the rate of interest.

Given to us

Jayla's bank account increased by 7% this year.

The amount that Jayla started with is b,

The amount that Jayla has now is c.

The equation that represents Jayla's Account

We know the general equation for compound interest is given as,

[tex]A = P(1+\dfrac{r}{100})^t[/tex]

Substituting the values we will get,

[tex]c=b(1 + \dfrac{7\%}{100})^1\\c = b(1.07)[/tex]

Hence, the equation that represents Jayla's current account balance with the initial amount is c=1.07b.

One number is 2 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 468 ​, find the numbers

Answers

Answer:

Step-by-step explanation:

Givens

Let the first number = x

Let the second number = 2x

Let the third number = x + 100

Total = 468

==============

Solution

x + 2x + x + 100 = 468                    Combine the xs

4x + 100 = 468                                Subtract 100 from  both sides

4x = 468 - 100

4x = 368                                          Divide by 4

x = 368/4

x = 92

===============

Answer

First number =                     92

Second num = 2 * 92=       184

Third number = 92 + 100= 192

Total                                    468

4×x = 4x

Step-by-step explanation:

We need to find an expression that is equivalent to 4×x

It means we need to find the product of 4 and x.

Here, 4 is a constant number and x is a variable.

It would mean that,

4×x = 4x

Amanda's monthly salary increased from $5,300 to $5,538.50. Mary's salary also increased by the same percentage as Amanda's.

If Mary was earlier getting $6,300, what is her new salary?

Answers

Answer:

$6,583.5

Step-by-step explanation:

Amanda's monthly salary increased by 4.5%. You can get the percentage by getting the increased amount in salary and dividing it by the previous salary of Amanda.

$5,538.50 - $5,300 = $238.5$238.5 ÷ $5,300 = 0.045 (4.5%)

In order to get the new salary of Mary, you have to multiply the same percentage, 4.5%, to Mary's previous salary, $6,300. This will give you the amount that will be added to her new salary.

$6,300 x 0.045 (4.5%) = $283.5$283.5 + $6,300 = $6,583.5

Mary's new salary is $6,583.5

The power, P (watts) , of a car engine is proportional to the square of its speed, s ( m / s ) . When s = 35 , P = 1580 . Work out the power (to 1 DP) when the speed is 30 m / s

Answers

Answer:

P=2200 , K=35

Step-by-step explanation:

The power, P (watts), of a car engine is proportional to the square of its speed, k%28m%2Fs%29; it means if you have two different powers and speeds, you will have a proportion

P%3Ak%5E2=P%5B1%5D%3Ak%5B1%5D%5E2 or

P%2Fk%5E2=P%5B1%5D%2Fk%5B1%5D%5E2

When given:

k=35, P=2200

Work out the power P%5B1%5D (to 1DP) when the speed is k%5B1%5D=40%28m%2Fs%29

so,

P=2200

 

k=35

k%5B1%5D=40

and you need P%5B1%5D

2200%2F35%5E2=P%5B1%5D%2F40%5E2

2200%2F1225=P%5B1%5D%2F1600

1.79592=P%5B1%5D%2F1600

1.79592%2A1600=P%5B1%5D

P%5B1%5D=2873.5 watts

If the speed is 30 m per second. Then the power of the car engine will be 1160.8 watts.

What is proportion?

A proportionate expression is one in which two items are equal.

The power, P (watts), of a car engine is proportional to the square of its speed s (m/s).

P ∝ s²

P = ks²

We have

s = 35

P = 1580

Then the value of k will be

1580 = (35)² × k

k = 1.2897

Then the equation will be

P = 1.2897s²

If the speed is 30 m per second. Then the power of the car engine will be

P = 1.2897 x 30²

P = 1160.8 watts

how do i do this 0.7x = 1.8 − 0.4x

Answers

Answer:

x = 1.636364

x = 1.64 (simplified)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.7x=1.8−0.4x

0.7x=1.8+−0.4x

0.7x=−0.4x+1.8

Step 2: Add 0.4x to both sides.

0.7x+0.4x=−0.4x+1.8+0.4x

1.1x=1.8

Step 3: Divide both sides by 1.1.

1.1x/1.1=1.8/1.1

x=1.636364

x = 1.64 (simplified)

Answer:

x = 1.636364

Explanation:

0.7x = 1.8 − 0.4x

Simplify both sides of the equation

0.7x = 1.8 − 0.4x

0.7x = 1.8 + −0.4x

0.7x = −0.4x + 1.8

Add 0.4x to both sides

0.7x + 0.4x = −0.4x + 1.8 + 0.4x

1.1x = 1.8

Divide both sides by 1.1

1.1x / 1.1 = 1.8 / 1.1

x = 1.636364

3. A computer is priced at $65,000 plus value added tax at 15%. What amount does the computer actually cost the customer?

Answers

Answer:

$74,750

Step-by-step explanation:

Given that,

The cost of a computer = $65,000 + value added tax at 15%

We need to find the amount the computer actually cost the customer.

Total cost = Cost of computer + VAT at 15%

[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]
