Answer:

[tex]f(8) = 81[/tex]

[tex](g\ o\ f)(x) = x^2 + 2x -4[/tex]

Step-by-step explanation:

Solving (a):

[tex]f(x) = x^2 + 2x +1[/tex]

[tex]g(x) = x - 5[/tex]

Solve for f(8)

We have:

[tex]f(x) = x^2 + 2x +1[/tex]

Substitute 8 for x

[tex]f(8) = 8^2 + 2*8 +1[/tex]

Solve

[tex]f(8) = 64 + 16 +1[/tex]

[tex]f(8) = 81[/tex]

Solving (b):

[tex](g\ o\ f)(x)[/tex]

This is solved by:

[tex](g\ o\ f)(x) = g(f(x))[/tex]

So, we have:

[tex]g(x) = x - 5[/tex]

[tex]g(f(x)) = f(x) - 5[/tex]

Substitute: [tex]f(x) = x^2 + 2x +1[/tex]

[tex]g(f(x)) = x^2 + 2x + 1 - 5[/tex]

[tex]g(f(x)) = x^2 + 2x -4[/tex]

Hence:

[tex](g\ o\ f)(x) = x^2 + 2x -4[/tex]

Answer:

-60

Step-by-step explanation:

-3(x + 10) + 2x = 30 becomes -3x - 30 + 2x = 30 after having performed the multiplication.  Combining like terms, we get -x = 60, so that x must be -60 (Answer 4)

Answer:

D

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the smallest number = x

The next number will be x + 1

x + x + 1 = 5

2x + 1 = 5          This is likely the answer to the question although it could be the equation above.

Answer:

have a great day

Answer:

C

Step-by-step explanation:

Answer:

yes those all seem to be correct, A, B, and D are the ones that are correct

Step-by-step explanation:

x'=53

σ=16

n=144

a) hypothesis

H0:µ=55

Ha:µ<55

This is a left tailed test

b) Test statistics

=(53-55)/(16/sqrt{144})

=-1.5

c)Pvalue at z=|-1.5|

pvalue= p(z>1.5)

=1-0.933193

=0.066807

=0.0668

Decision

since pvalue>alpha(0.05) fail to reject the null hypotheis.

Conclusion

There is not sufficient evidence to support the claim the new computer program has not reduce the time to retrieve the data.

d)since Pvalue>alpha(0.025),so fail to reject the null hypothesis.

No, change in conclusion.  

Answer:

45

Step-by-step explanation:

689 - 464 = 225

225 /5 = 45

Answer:

D

Step-by-step explanation:

As you can see from the image attached below, the equation that is being graphed is

F(x) = [tex]\frac{x}{(x+4)(x-1)}[/tex]

This equation splits off into various directions because the denominator is turns into a quadratic equation. Once solved it provides two values for which the quadratic equation would equal zero. Since this equation is the denominator 0 would give a null value and is why on the graph there is no y value for 1 or -4. Yet all other values are valid and have an different y output.

Answer:

90

Step-by-step explanation:

the movie was 25% shorter

25% of 120 is 30

120-30=90

Answer:

500 + (40x)

Step-by-step explanation:

she already has 500 in her bank account and there are multiple weeks. 40 dollars per week would be 40x since we don’t know how many weeks. then put it in an equation!

Answer:500 + 40w = m

Step-by-step explanation:

500 is the amount you had already then you add 40 per a week so you times that by w depending on the weeks and m is money overall.

this should be the answer

Hoped this helped

Answer: To convert a number into percent multiple it by 100 and then add the percent sign. These examples convert the numbers 23 and 158 to percents. To convert a number with a decimal into percent, multiply it by 100 and add the percent sign. These examples convert 0.4580; 0.0257; and 0.00458.

Answer:

[tex]4 \times - 2 {}^{n - 1} [/tex]

Step-by-step explanation:

Use the formula.

[tex]f(n) = f(1) \times {r}^{n - 1} [/tex]

where f(1) is the first terms, r is the common ratio, and n is our undefined term.

4 is our first term. so

f(1)=4.

Our common ratio is -2 so

r=-2.

[tex]4 \times - 2 {}^{n - 1} [/tex]

Answer: Reply to this with the "following equations" so i can have those to work from.

Answer: 1/6 of the paint went to each container

Step-by-step explanation: Since we know he had 2/3 of a gallon of paint and they were divided into 4 containers, we have to divide 2/3 by 4 and when you do that you get 0.16666 continuous but in fraction for you arrive at 1/6 of a gallon of paint

Step-by-step explanation:

Answer:

the radius of the cylinder is 1.91 cm

Step-by-step explanation:

Given;

curved area of the cylinder, A = 24 cm²

height of the cylinder, h = 2.0 cm

The curved surface area of a cylinder is given as follows;

Curved surface area = 2πrh

where;

r is the radius of the cylinder

24 = 2πrh

r = 24 / (2πh)

r = 24 / (2π x 2)

r = 24 / (4π)

r = 1.91 cm

Therefore, the radius of the cylinder is 1.91 cm

Answer:

Well I guess this is a math problem but the middle time would be: 6 hours and 30 minutes.

Step-by-step explanation:

Adding 6 hours to 2 pm makes 8:00 on the dot at night. Adding 30 minutes to 8:00 would be 8:30. There you have your answer.

B looks like the correct answer.
