Graham and Hunter are circus performers. A cable lifts Graham into the air at a constant speed of 1.5 ft/s. When Graham’s arms are 18 ft above the ground, Hunter, who is standing directly underneath Graham, throws Graham a ball as the cable continues to lift him higher. Hunter throws the ball from a position 5 ft above the ground with an initial velocity of 24 ft/s. Which system of equations can be used to model this situation?

Answers

Answer 1
Answer: The answer to the question above as to which system of equations can be used to model the situation of Graham and Hunter when a cable lifts Graham into the air at a speed of 1.5 ft/s and Hunter throws the ball from a position of 5 ft. above the ground with an initial velocity of 24 ft/s. the equation will be : H = 18t + 1.5t - 16t ^ 2
H = 5 + 24t - 16t ^ 2
Answer 2
Answer:

The equation of Graham cable is h(t) = -16t² + 1.5t + 18 while The equation of Hunter ball is h(t) = -16t² + 24t + 5

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

The height of a projectile at time t is:

h(t) = -16t² + ut + h'

Where u is the initial velocity and h' is the initial height.

The equation of Graham cable is:

h(t) = -16t² + 1.5t + 18

The equation of Hunter ball is:

h(t) = -16t² + 24t + 5

Jillian is selling boxes of cookies to raise money for her basketball team. The 10 oz. box costs $3.50, while the 16 oz. box costs $5.00. At the end of one week, she collected $97.50, selling a total of 24 boxes. The system of equations that models her sales is below. x+ y= 24 3.50x + 5.00y = 97.50 Solve the system of equations. How many 10 oz. boxes were sold?a. 6
b. 9
c. 12
d. 15

Answers

x + y = 24 <=> x = 24 - y. So far we have the value of x relative to the value of y. Now we can replace it in the second equation: 3.5x + 5y = 97.5 <=> 3.5 * (24 - y) + 5y = 97.5 <=> 84 - 3.5y + 5y = 97.5 <=> 1.5y = 97.5 - 84 <=> 1.5y = 13.5 <=> y = 13.5/1.5 <=> y = 9. And since x was 24 - y, this means that x = 15. So the answer is D.

Pamela has 4 pink ribbons, 3 green ribbons, and 1 blue ribbon. what fraction of Pamela's ribbons are green?

Answers

The total number of ribbons is 8 because 4 + 3 + 1 is 8
The number of green ribbons is 3
That means that 3 out of the 8 ribbons are green
Answer: 3/8
4 + 3 + 1 = 8
1 of those 8 is green
1/8

Jerry had an average score of 85 on his first 8 quizzes. He had an average score of 81 on his first nine quizzes. What score did he earn on his ninth quiz? side note: I got 49 the first time i tried it but when i checked it, it was wronfg

Answers

Well, let's calculate how many points in total he got so far!

He did 8 quizzes, on average 85 points: 85*8=680 points.

He scored a number of points in his ninth quiz, let's call this number "x".

If we want to calculate the average after the ninth quiz, we take the sum of points then (which is 680+x) and we divide it by 9:

(680+x)/9

we also know that this is equal to 81:

(680+x)/9=81

((680+x))/(9)=81

multiply both sides by 9:

(680+x)}=729

substracting 680 from both sides:

x=49

well, i got 49 too.

I really can't see where the mistake could be?

where did you check it? my best guess is that the place where you checked it had a typo...?

Given f(x)=x+5 all over 3, solve for f^-1(3) (A. -1; B. 14; C. 18; D. 21)

Answers


f^-1 means finverse
find finverse then subsitute 3 for x
to solve

replace f(x) with y
solve for x
switch x with y
replace y with finverse or f^-1

f(x)=(x+5)/3
y=(x+5)/3
3y=x+5
3y-5=x
3x-5=y
finvers=3x-5

fiinverse(3)=3(3)-5
finverse(3)=9-5
