Answer:

$4.88

Step-by-step explanation:

Jessica made $16 mowing a neighbors yard

She brought a craft kit for $7.37

16-7.37

= 8.63

She used $3.75 to buy food for a food drive

8.63-3.75

The largest of the Great Pyramids in Egypt was built with a square base, having edges that measured 754 feet and a height of 418
12345 [234]

Answer:

79,213,229 ft3

Step-by-step explanation:

The volume of a pyramid is given by the following formula:

Volume = (1/3) * B * h

Where B is the base area and h is the height.

The side of the base is 754 feet, so the base area is:

B = 754^2 = 568516 ft2

Then, the volume of the pyramid is:

Volume = (1/3) * 568516 * 418 = 79213229.33 ft3

Rounding to the nearest cubic foot, we have:

Volume = 79,213,229 ft3

Please help me that’s would be great and I promise to mark brainlest!!

Option A is correct.

If we evaluate the function at x=0, i.e. at the beginning, we have

f(0)=75 \cdot 2^0 = 75 \cdot 1 = 75

with each minute, you multiply the current number of cell by 2, so they double every minute.

Option B is incorrect, because if the number of cells increases by 2 every minute, the function would be

f(x) = 75 + 2k

Option C is incorrect, because after one minute (i.e. when x=1) we have

f(1) = 75\cdot 2^1 = 75 \cdot 2 = 150

cells, so 75 is not the number of cells after one minute

Option D is incorrect in both the initial value and the behaviour of the function
