Answer: -3

So, first off, judging from the h(x) graph, h(x)=-2x–1
So this is compositions or something like that; it’s been a year since I’ve done calculus but here we go:
First, you must find f(6) by replacing every x in that function by 6
f(6) = (1/2)(6) – 4
f(6) = (6/2) – 4
f(6) = 3 – 4
f(6) = -1
Now, since you’ve found f(6), now to find h(-1) (since f is -1 and h( f(6) ) is h(-1) )
h(-1) = 2(-1) – 1
h(-1) = -2 – 1
h(-1) = -3

So, the answer is -3

Answer:

B.) 7 seconds

Step-by-step explanation:

We are given that the ant can crawl 95 centimeters in 5 seconds, which means that it can crawl 19 centimeters in 1 second (95 centimeters/5 seconds). Now you need to divide 19 from 133 (133 centimeters/19 centimeters per second), and you get 7 seconds.

Leigh is renting a moving van The function C (d) = 0.12d + 25 is used to relate the cost, C, in dollars of the rental after Leigh
uses the van for d miles. What is the interpretation of the slope for this function? (1 point)
The initial cost of the moving van is $0.12
The additional cost is $25 for each additional mile the van is driven
The initial cost of the moving van is $25.
The additional cost is $0.12 for each additional mile the van is driven

Answers

Answer:

The additional cost is $0.12 for each additional mile the van is driven ⇒ D

Step-by-step explanation:

The form of the linear function is

f(x) = m x + b, where

m is the rate

b is the initial value

In our question

The function C(d) = 0.12 d + 25 represents the cost C in dollars of the rental van uses for d miles

→ Compare it with the form of the linear function above

∴ m = 0.12

∴ b = 25

∵ The cost C depends on the number of miles d

∴ $0.12 is the cost per mile ⇒ additional cost for each additional mile

∴ $25 is the initial cost ⇒ initial cost of the moving the van

The interpretation of the slope for this function is:

The additional cost is $0.12 for each additional mile the van is driven

Answer:

+0.12

Step-by-step explanation:

The additional cost is 0.12 cents for each additional mile the van is being driven.

A student has passed 60 percent of the 20 quizzes he has written so far successfully. If the student writes 50 quizzes during the year, and passes 80 percent of the remaining quizzes successfully, what would his average percentile be?

Answers

Answer:

A student has passed 60 percent of the 20 quizzes he has written so far successfully mean:

successfully quizzes = 60 % of 20 quizzes = ( 60 / 100 ) * 20 = 60 * 20 / 100 = 1200 / 100 = 12

The remaining quizzes = 50 - 20 = 30 quizzes

80 percent of the remaining quizzes successfully mean:

The remaining successfully quizzes = 80 % of 30 = ( 80 / 100 ) * 30 = 80 * 30 / 100 = 2400 / 100 = 24

Total successfully quizzes = 12 + 24 = 36

Average = ( 36 / 50 ) * 100 % = 0.72 * 100 % = 72 %

You’d like to see how many baseball and soccer games you can attend this spring. Travel time for basketball games is 2 hours and soccer games is 1 hour. You would like to spend no more than 15 hours traveling to the games. In total, you would like to attend at least 8 games.

Answers

4 basketball games and 7 soccer games

We have to attend 7 basketball games and 1 soccer game.

Given, we had two types of game namely basketball and soccer.

Travel time for basketball games is 2 hours and soccer games is 1 hour.

Let no. of basketball games be x and no of soccer games be y.

According to the question we would like to attend at least 8 games, so we have the inequality  [tex]x+y\geq 8[/tex]

And  we would spend no more than 15 hours traveling to the game, so [tex]2x+1y\leq 15[/tex].

[tex]x+y=8\\[/tex]

[tex]2x+1y=15\\[/tex]

Answers

Answer:

8 miles

Step-by-step explanation:

Given

Represent the police station with P, Library with L; Fire station with F

The first statement can be represented as:

[tex]L - P = P - F - 3[/tex]

The second can be represented as:

[tex]L - P = 5[/tex]

The answer is 55. You need to use the rules above to find the actual measure for angle b

Answers

209 + 96 + 55 = 360

Step-by-step explanation:

A circle is 360 degrees

209 is part of the circle so find the difference between 360 and 209

360 - 209 = 151

If the two angles are equivalent to 151, then we find the difference between 151 and 96 to get the measurement for angle b

151 - 96 = 55

His mother was a journalist, and his father was a professor. As a kid he played sports, did well in school, and liked acting. His passion for acting goes back to playing with his brother when they were little. Reeve acted in his first play at the age of nine. After attending college, taking acting classes, and acting in many plays and movies, Reeve landed his biggest role. In 1978, he played the title role in Superman. He received very positive reviews for his performance and starred as Superman in all the sequels. Reeve was soon acting as the lead role in dozens of movies after Superman. Once well-known, Reeve used his celebrity status for good causes, such as visiting very sick children through the Make-A-Wish foundation. He was also a track and field coach at the Special Olympics.Besides acting, Reeve was also a licensed pilot and liked horseback riding. He learned to ride horses for a movie role, and he continued riding in his free time. Unfortunately, while riding one day in 1995, Reeve fell from his horse and became paralyzed from the neck down. Being confined to a wheelchair did not hold back Reeve from being socially active, and after many surgeries and rehabilitation, he decided to dedicate his life to helping people with spinal-cord injuries. He created the Christopher Reeve Foundation, which supports the improvement of the lives of people with disabilities and helps fund research to find a cure for paralysis. He was also politically active, working with senators to make sure that people with disabilities were treated fairly in the workplace. Reeve received many awards for his dedication to public service. He also wrote two books about his experiences, and a documentary was made about his life. Reeve passed away in 2004, but his legacy lives on today. He touched the lives of many people and showed us what it means to overcome extreme odds by never giving up.A yearbook page for Christopher Reeve includes "Best at: Helping Others."
