Answer:

1.24 ft

Step-by-step explanation:

the volume of sphere = 4/3π.r³ = 1

=> r³ = 3/(4π)= 3/(12.56) = 0.239

r = ³√0.239

r = 0.62

d = 2×0.62 = 1.24 ft

Answer:

volume \ of \ sphere = \frac{4}{3} \pi  r^3 \\\\1 =\frac{4}{3} \pi r^3\\\\r^ 3 = \frac{3}{4\pi} \\\\r = (\frac{3}{4\pi })^{\frac{1}{3} } \\\\r = 0.62ft\\\\diameter = 2 * 0.62 = 1.24ft

14) Find the slope of the line containing the points (5, 3) and (-7, 2).
Zina [86]

Answer:

1/12

Step-by-step explanation:

Step one:

given data

the line containing the points (5, 3) and (-7, 2).

x1= 5

y1= 3

x2= -7

y2=2

Step two:

The slope is given as

Slope= y2-y1/x2-x1

substitute

Slope= 2-3/-7-5

Slope= -1/-12

Slope = 1/12

You deposit the same $10,000 into a bank account at 4% annual interest. How long will it take for the $10,000 to compound to $30
Readme [11.4K]

Answer:

time = 28 years

Step-by-step explanation:

Given,

principal amount = $10,000

rate = 4%

total amount = $30,000

According to compound interest formula

A\ =\ P(1+r)^t

where, A = total amount

            P = principal amount

            r = rate

            t = time in years

so, from the question we can write,

30000\ =\ 10000(1+0.04)^t

=>\ \dfrac{30000}{10000}\ =\ (1+0.04)^t

=>\ 3\ =\ (1.04)^t

by taking log on both sides, we will get

=> log3 = t.log(1.04)

=>\ t\ =\ \dfrac{log3}{log1.04}

=> t = 28.01

So, the time taken to get the amount from 10000 to 30000 is 28 years.
