A

The given composition function is combination is F(x)=√x+1 and G(x)=3x. Therefore, option D is the correct answer.

The given function is G(F(x))=3(√x+1).

F(x)=√x+1 and G(x)=3x

The composite function is G(F(x))

Replace x by √x+1 in 3x, we get

3(√x+1)

Therefore, option D is the correct answer.

You buy tomatoes in 25 lb cases one portion of salad requires. 75 oz of tomatoes how many portions can be made with one case

Answers

1 lb = 16 oz
so 25 lbs = 400 oz

if each salad requires 75 oz and you have 400 oz, divide 400/75

400/75 = about 5.3

since you can’t really have a third of a salad, you will be able to make 5 FULL portions with one case

final answer: 5 portions

Answer:4(5x+1)

Step-by-step explanation: you want to subtract the numbers 4+5x(6-2)/4+5x(4) so you'll need to  multiply 5 and 4 so 4+5x*4 but i'm goin to make it smaller so it would be 4+20x  but you have to rearrange it instead of it being 4+20x it would be 20x+4 .And the common factor would be 4(5x+1).

Victoria is at an elevation of 150 feet. She hikes down to an elevation of 120 feet in 40 minutes.
Then she hikes down to an
elevation of 100 feet in 30 minutes.

What is her average rate of descent, in feet per minute, from 150 feet to 120 feet?

Answers

The Victoria's average rate of descent by hiking down from an elevation of 150 feet to an elevation of 120 feet in 40 minutes is equal to 0.75 feet per minute.

How to determine the average rate of descent of a hiker

Geometrically speaking, the average rate of descent (r), in feet per minute, is represented by a secant line, which represents in this case the change in elevation (Δz), in feet, divided by the change in time (Δt). A mathematical description of the formula is shown below:

r = Δz/Δt     (1)

If we know that Δz = 30 ft and Δt = 40 min, then the average rate of descent is:

r = 30 ft/40 min = 0.75 ft/min

The Victoria's average rate of descent by hiking down from an elevation of 150 feet to an elevation of 120 feet in 40 minutes is equal to 0.75 feet per minute. [tex]\blacksquare[/tex]

For the equation z – 14 = 29. Jaun says that the solution is 33.Check solution work by substitutions it into the equation .Is his solution correct. Explain

Answers

Answer:

Jaun's solution is incorrect.

Step-by-step explanation:

If Jaun's solution to the equation is 33, we can check this by substituting z=33 and solving 33 - 14 = 29. Since 33-14=19 and 19 does not equal 29, Jaun's answer is incorrect.

The product of 296 and 2.423 rounded to the nearest hundred would be 717.20

What is rounding a number to some specific place?

Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.

Rounding to some place keeps it accurate on the left side of that place but rounded or sort of trimmed from the right in terms of exact digits.

We need to find the product of 296 and 2.423

296 x 2.423 = 717.20

Thus, 717.20 rounded to the nearest hundred .

Grandma baked 96 cookies and gave them to her grandchildren. One of the grandchildren, Cindy, received c fewer cookies than she would have received had all of the cookies been evenly divided among the 8 grandchildren.How many cookies did Cindy receive? Write your answer as an expression.

Answers

Answer: 29 cookies.

Step-by-step explanation: 96/8=32       32-3=29        boom. maths.

The number of cookies baked by Grandma= 96

If she divides them evenly amount 8 children, then by division operation the number of cookies received by each child = (number of cookies) ÷ (number of children)

= (96) ÷ (8) = 12

Since, Cindy, received c fewer cookies than she would have received had all of the cookies been evenly divided among the 8 grandchildren.

Hence, the number of cookies received by Cindy = 12-c

A=p2-2p-3

Step-by-step explanation:

The area for a triangle is given by:

A=1/2bh

The base is p + 1 and the height is 2p - 6. Therefore:

A=1/2(p+1)(2p-6)

Simplify the second term:

A=(p+1)(1/2)(2p-6)=(p+1)(p-3)

Distribute:

A=p(p-3)+1(p-3)

Distribute:

A=p2-3p+p-3

Combine like terms:
