If f(x) = 7x +3 and g(x) = (x-4,
what is (fºg)(40)?
Answer: 280x^2 - 1000x - 480
Step-by-step explanation:
((7x + 3) * (x - 4))(40)
use foil
7x^2 - 28x + 3x -12
(7x^2 - 25x - 12) (40)
280x^2 - 1000x - 480
6|3-2z| = 42??
How do we answer this??
[tex]6(3 - 2z) = 42 \\ 18 - 12z = 42 \\ - 12z + 18 - 42 = 0 \\ - z + \frac{3}{2} - 2 = 0 \\ z = - \frac{3}{2} + 2[/tex]

Round the fraction to the nearest whole number.
3.
1/3
0
The answer would be 0 because 2/3 wouldn't be able to round up to a number so it would be 0.But if what you are saying is 3 1/3 rounded to the nearest whole number it would be 3
23. According to one of Tolkien's essays, there were 144 elves originally created by the gods in Middle-Earth. If their numbers tripled every century after that, how many elves were there 1000 years after the creation of Middle-Earth?
A) 432,000 elves
B) 59,049,000 elves
C) 432 elves
D) 8,503,056 elves
Answer:
D
Step-by-step explanation:
elves in 1000 years = elves now x (rate of increase)^time
elves increase every century. there are ten years in a century. thus time = 1000/100 = 10 years
144 x (3)^10 = 8,503,056 elves

the cost of pre-sale ticket for the dance is $3.00 The tickets at the door will cost $5.00. What is the percent increase of the ticked from pre-sale to at the door price?
Answer:
66.666%
Step-by-step explanation:
Ok first of all the first ticket is $3.00 the second one is 5.00. Important to note that the difference is $2.00. So we do $2.00/$3.00 which gives the answer of 66.666(recurring). Therefore your answer is 66.666%

The area of a parallelogram is 315 square inches. If the parallelogram has a base length of 21 inches, what is the height of the parallelogram?
Answer:
Area of parallelogram is =base *height
Given area of parallogram is 315square inches
Therefore, area of parallogram =b*h
Therefore area of parallogram =21*h
Therefore, 315=21*h
Therefore 315/21=h
Therefore, 15 =height
Height of parallogram is 15 inches

A chemist examines 25 geological samples for bromide concentration. The mean bromide concentration for the sample data is 0.502 cc/cubic meter with a standard deviation of 0.0313. Determine the 98% confidence interval for the population mean bromide concentration. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answer:
The critical value that should be used is T = 2.492.
The 98% confidence interval for the population mean bromide concentration is between 0.486 cc/m³ and 0.518 cc/m³
Step-by-step explanation:
We have the standard deviation for the mean, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 2.492, which is the critical value that should be used.
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.492\frac{0.0313}{\sqrt{25}} = 0.016[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 0.502 - 0.016 = 0.486 cc/m³
The upper end of the interval is the sample mean added to M. So it is 0.502 + 0.016 = 0.518 cc/m³
The 98% confidence interval for the population mean bromide concentration is between 0.486 cc/m³ and 0.518 cc/m³

A TV has a listed price of $671.98 before tax. If the sales tax rate is 7.5%, find the total cost of the TV with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
The price of the TV with the sales tax included is $ 722.38.
Step-by-step explanation:
Given that a TV has a listed price of $ 671.98 before tax, and the sales tax rate is 7.5%, to find the total cost of the TV with sales tax included the following calculation must be performed:
671.98 + (671.98 x 0.075) = X
671.98 + 50.3985 = X
722.3785 = X
Therefore, the price of the TV with the sales tax included is $ 722.38.

This is the last question I need please help (the first one to help will be marked brainliest!)
Answer:
x = 19
Step-by-step explanation:
The 5x + 30 should also = 125, since they both have the same angle.
So you can make this equation:
125 = 5x + 30
125 - 30 = 5x
95/5 = x
x = 19
Step-by-step explanation:
125°=5x+30°
125-30= 95
95÷5=19
so x = 19
