Answer:

Option B False

Step-by-step explanation:

we know that

The <u>Cavalieri's principle</u> states that if two or more figures have the same cross-sectional area at every level and the same height, then the figures have the same volume

therefore

The cross-sectional area at every level must be the same

so

The statement is False

F(x)= 5x^2+6, g(x)= 7x find (f o g)(x), find (g o f)(x), find f(g(-4)), fine g(f(5))
KiRa [710]

(f o g)(x) = 245x^2+6\\(g o f)(x) = 5x^2+42\\ f(g(-4)) = 3926\\g(f(5)) = 917

Step-by-step explanation:

Given

f(x) = 5x^2+6\\g(x) = 7x

So

(f o g)(x) = 5(7x)^2+6\\= 5(49x^2)+6\\=245x^2+6\\(g o f)(x) = 7(5x^2+6)\\= 35x^2+42\\(fog(x))=245x^2+6f(g(-4)) = 245(-4)^2+6 \\=245(16)+6\\=3920+6\\=3926\\g(f(x)) = 35x^2+42\\g(f(5)) = 35(5)^2+42\\=35(25)+42\\=875+42\\=917

Hence,

(f o g)(x) = 245x^2+6\\(g o f)(x) = 5x^2+42\\ f(g(-4)) = 3926\\g(f(5)) = 917

ArbitrLikvidat [17]

Answer:

32.9 inches

Step-by-step explanation:

this can be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base = 49

c =  hypotenuse = diagonal = 59

l² + 49² = 59²

l² = 59² - 49²

3481 - 2401 = 1080

find the square root

Calculate the average speed of the car in m/s
Alina [70]

Answer:

14.4 m/s

Step-by-step explanation:

The speed of the car can be found by dividing the distance by the time. The distance is 0.8m 9 times or 0.8(9)=7.2 meters and the time is 0.5 seconds

s=\frac{d}{t} \\s=\frac{7.2}{0.5} \\s=14.4

Which of the following is the most profitable investment for a candy shop that earns $1 revenue per pound of candy? (5 points) G
rewona [7]

Then the most profitable investment is the first machine (third option) because for each dollar, it produces 2 pounds of candy.

<h3>Which of the following is the most profitable investment?</h3>

The first option is a worker that costs $10 per hour and produces 8lb, then this worker gives:

8lb/$10= <em>0.8 pounds per dollar.</em>

The second worker costs $12 per hour, and produces 16lb per hour, so this worker gives:

16lb/$12 = <em>1.33 pounds per dollar.</em>

The third option is a machine that cost $5 per hour and produces 10lb per hour, then:

10lb/$5 = <em>2 pound per dollar.</em>

The last option costs $8 per hour, and produces 14 pounds per hour, then:

14lb/$8 = <em>1.75 pounds per dollar.</em>

Then the most profitable investment is the first machine (third option) because for each dollar, it produces 2 pounds of candy.

Slope is 3, and (1,4) is on the line
Novosadov [1.4K]
The first step is since you know what the slope is, you can just plug that into the equation. We now have y=3x+b, b being the y intercept.
3 is equal to 3/1, and you can use that to find the Y intercept. Start at the point that they game you and go up 3 and over 1. But this makes you further away from the Y axis, so you want to do the opposite. Go down 3 and over 1.\
This makes you end up on the Y intercept at (0,1)
