Answer:

313 in.

Step-by-step explanation:

V = r × h

10,000 = 32 × ?

10,000 / 32 = 312.5

312.5 rounded to the nearest whole number is 313 in.

Answer: 39 in.

Step-by-step explanation:

Radius formula: r = d ÷ 2

Diameter (d) = 32 in.

Radius (r) = 16 in.

Volume (V) = 10,000π in.³

Volume of a cylinder formula: V = Ah

A = π r²

V = π r² h

10,000π = π (16)² × h

10,000 = 256 × h

h = 10,000 ÷ 256

h = 39.1 in. = 39 in.

Do the ratios 9/4 and 11/6 make a proportion please explain. Thank You!

svetoff [14.1K]

No they're not proportionate because 9 divided by 4 = 2.25 and 11 divided by 6 is 1.83 so they're not the same in value

7.1 as a fraction or mixed number in simplest form?

Andreas93 [3]

The simpliest form is 71/10, the fraction

Step-by-step explanation:

Since this isn't a really small (1/1000000000) or really big (like the radius of the earth) number you don't need the standard notation, so the fraction 71/10 is the simpliest because there is only a decimal, so it can be a fraction of ten.

Help me answer these questions please 15, 19 and 20 please

SpyIntel [72]

Answer:

15) K'(t) = 5[5^(t)•In 5] - 2[3^(t)•In 3]

19) P'(w) = 2e^(w) - (1/5)[2^(w)•In 2]

20) Q'(w) = -6w^(-3) - (2/5)w^(-7/5) - ¼w^(-¾)

Step-by-step explanation:

We are to find the derivative of the questions pointed out.

15) K(t) = 5(5^(t)) - 2(3^(t))

Using implicit differentiation, we have;

K'(t) = 5[5^(t)•In 5] - 2[3^(t)•In 3]

19) P(w) = 2e^(w) - (2^(w))/5

P'(w) = 2e^(w) - (1/5)[2^(w)•In 2]

20) Q(W) = 3w^(-2) + w^(-2/5) - w^(¼)

Q'(w) = -6w^(-2 - 1) + (-2/5)w^(-2/5 - 1) - ¼w^(¼ - 1)

Q'(w) = -6w^(-3) - (2/5)w^(-7/5) - ¼w^(-¾)
