Answer:

8.40049 × 10^7

Step-by-step explanation:

Answer: 9

Step-by-step explanation: Parallel lines have the same slope.

So a line parallel to this would also have 9 as its slope.

Answer:The 9 in the hundredths place is 0.1x the value of the 9 in the tenths place.

Step-by-step explanation:

Every place going forward is 10x forward, so this means that every place going backwards is 0.1x.

Answer:

- 4

Step-by-step explanation:

Step 1:

4 ( 2 - w ) + w = 20           Equation

Step 2:

8 - 4w + w = 20       Multiply

Step 3:

8 - 3w = 20       Combine Like Terms

Step 4:

- 3w = 12     Subtract 8 on both sides

Answer:

w = - 4

Hope This Helps :)

Answer:

w = -4

Step-by-step explanation:

4(2 - W) + w = 20

Distribute:          

8 - 4w + w = 20

Subtract 8 from both sides:

-4w + w = 12

Simplify:

-3w = 12

Divide:

w = -4

Double check your work by substitution:

4(2 - W) + w = 20

4(2 - (-4)) + (-4) = 20

4(6) + (-4) = 20

24 + (-4)= 20

20 = 20

Since we know that 20 does equal 20, we can conclude that the final answer is:

w = -4

Answer:

an integer divided by an integer will always result in a fraction- therefore, the resultant number will not be an irrational number and there will always be either a repeated pattern or a single set of decimal points. Take for example 3/4= 0.75. As you can see the number is a rational number that is real.

Step-by-step explanation:

An integer divided by an integer is sometimes not an integer.

Answer:

45.6

Step-by-step explanation:

We can write a proportion to solve

12 roses     18 roses

------------ = -----------

30.4            x

Using cross products

12x = 30.4 * 18

12x=547.2

Divide each side by 12

12x/12 = 547.2/12

x = 45.6

Answer:

  y = -10

Step-by-step explanation:

Using the point-slope form of the equation for a line, we can write the equation as ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y -2 = -3(x -5)

Using the values for the other point, this becomes ...

  y -2 = -3(9 -5)

  y = -3(4) +2

  y = -10

Answer:

Step-by-step explanation:

x intercept is where the line is crossing the x axis or where y=0

y intercept is where the line crosses the y axis or where x=0

to find them, set other ting to zero

3/5x+1/3y=1/15

xintercept, set y=0

3/5x+1/3(0)=1/15

3/5x+0=1/15

3/5x=1/15

times 5/3 both sides

x=1/9

xintercept is x=1/9

yintercet

set x=0

3/5(0)+1/3y=1/15

0+1/3y=1/15

1/3y=1/15

times 3/1 both sides

y=1/5

yintercept is y=1/5

xint is x=1/9

yint is y=1/5

Answers:

y = -25

y = 7

Step-by-step explanation:

Find the derivative of the function.

[tex]\frac{dy}{dx} y = 3x^2-6x-9[/tex]  

The zeros of the derivative are the local extrema (Maximum & Minimum)

[tex]0 = 3x^2-6x-9[/tex]

Take out the greatest common factor, 3, to get this equation:

[tex]0 = 3(x^2-2x-3)[/tex]

Factor out the brackets.

[tex]0 = 3(x - 3) ( x + 1 )[/tex]

You are left with two possible values for x:

x = 3

x = -1

By substituting each value into the original function [tex]y = x^3 - 3x^2 - 9x + 2[/tex], you get the equation of any horizontal tangents to the curve.

When x = 3:

[tex]y = (3)^3 - 3(3)^2 - 9(3) + 2 = -25[/tex]       Meaning y = -25

When x = -1:

[tex]y = (-1)^3 - 3(-1)^2 - 9(-1) + 2 = 7[/tex]    Meaning  y = 7

Answer:

I think it would be B)

Step-by-step explanation:

This problem seems badly worded and/or vague.

It looks like you plugged x = 3 into the inverse [tex]f^{-1}(x)[/tex] function to get 3 as the output, which is correct.

However it seems like your teacher wants you to find the (x,y) point on f(x). This means s/he is asking "what x value will get us y = 10?" As you found through working with the inverse, the x value x = 3 does that.

We can see it as such

f(x) = 3x+1

f(3) = 3*3+1

f(3) = 10

So in a sense, you were working backwards.

The point (3,10) is on the graph of f(x)

While the point (10,3) is on the graph of [tex]f^{-1}(x)[/tex]

It's likely your teacher wants you to select choice C

Answer:

5000

Step-by-step explanation:

Assuming they both work 365days

roughly 52 weeks

number of time sherry is paid per year = [tex]\frac{52}{2} = 26[/tex]

because she is paid every two weeks

number of time donna is paid per year = [tex]4[/tex]

because she is paid 4 times a year (quarterly)

let s =  amount sherry is paid biweekly

let d = amount donna is paid quarterly

[tex]s = \frac{26000}{26} = 1000\\\\d = \frac{26000}{4} = 6500\\\\difference = 65000 - 1000 = 5000\\[/tex]

Answer:

5500

Step-by-step explanation:

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

Work Shown:

P = 10,000 = deposit

r = 0.04 = decimal form of 4% interest rate

n = 4 = we're compounding 4 times a year

t = 5 years

-------------

A = P*(1+r/n)^(n*t) .... compound interest formula

A = 10,000*(1+0.04/4)^(4*5)

A = 12,201.9003994797

A = 12,201.90

After 5 years, there is $12,201.90 in the account.

This is assuming you do not deposit any more money, and it also assumes that you don't take any money out during the 5 year timespan either.

Answer: Rejecting the mean weight of each cake as 500 gram when H subscript 0 equals 500

Step-by-step explanation:

Given that :

Null hypothesis : H0 =500

Alternative hypothesis : Ha < 500

Type 1 Error: Type 1 error simply occurs when we reject the Null hypothesis when the Null is true. Alternatively, type 11 error occurs when we fail to reject a false null hypothesis.

Hence, in the scenario above, a type 1 error will occur when we reject the mean weight as 500 even though the Null hypothesis is True.

Answer: A) Rejecting the mean weight of each cake as 500 grams when H₀ = 500.

Step-by-step explanation:

Type I error is when we incorrectly reject a true null hypothesis

Step-by-step explanation:

If you look at the number line and start counting from -8 and count 9 to the right then the number that you end on is the answer.

Answer:-1.2 Degree Fahrenheit.

Step-by-step explanation:

Since,

The average daily changes,   total changes/number of days

Here,

The total changes = - 16.8° F ( - sign shows the decreasing )

And, the number of days = 14

Hence,

⇒ The average daily rate of change in the high temperature in degrees Fahrenheit is -1.2° F.

-16.8 / 14 = - 1.2 per day
