I can't make out what the radius of the sphere is, but the equation you're looking for is:

V=\frac{4}{3}\pi r^3

For example:

If the radius of a sphere is 5 m, it's volume would be,

V=\frac{4}{3}\pi (5)^3

V=\frac{4}{3} (3.14)(5)^3

V=\frac{4}{3}(3.14)(125)

V=523.6 m^3

Answer:

W can be 3, 4, and 5

Step-by-step explanation:

If it is less than 18 and higher than 6 then I think those, 3 times 3, 4, and 5, would be in between your range.

Find the point on the line y = 4x + 3 that is closest to the origin.
umka21 [38]
That point will be where the perpendicular line through the origin intersects the given line.
.. (-1/4)x = 4x +3
.. -3 = (17/4)x
.. -12/17 = x

The point on the given line that is closest to the origin is (-12/17, 3/17).

Westkost [7]

Answer:

The total interest earned at the end of the year was $ 820, and the interest generated by the total deposited was 10.25%.

Step-by-step explanation:

Given that last year, Manuel deposited $ 7000 into an account that paid 11% interest per year and $ 1000 into an account that paid 5% interest per year, and no withdrawals were made from the accounts, to determine what was the total interest earned at the end of year and what was the percent interest for the total deposited, the following calculations must be performed:

7000 x 0.11 + 1000 x 0.05 = X

770 + 50 = X

820 = X

8000 = 100

820 = X

820 x 100/8000 = X

82,000 / 8,000 = X

10.25 = X

Therefore, the total interest earned at the end of the year was $ 820, and the interest generated by the total deposited was 10.25%.

The point-slope form of the equation of the line that passes through (–5, –1) and (10, –7) is . What is the standard form of the
kvasek [131]

Answer:

Point-Slope form:  y+1=-\frac{6}{15}(x+5)\\

standard form:  2x+5y=-15


Step-by-step explanation:

The standard form is given by: Ax+By=C

The point-slope form is given by: y-y_1=m(x-x_1)


  • <em>Let's call (-5,-1) as point (x_1,y_1), and</em>

<em>point (10,-7) as point (x_2,y_2)</em>

  • <em>We also know that the slope m is given by m=\frac{y_2-y_1}{x_2-x_1}</em>

Let's find the slope:

m=\frac{-7-(-1)}{10-(-5)}=-\frac{6}{15}


1. So, point slope form can be written as:

y-(-1)=-\frac{6}{15}(x-(-5))\\y+1=-\frac{6}{15}(x+5)\\


2. Rearranging this equation and bringing all x's and y's to one side and the number to another side will give us the standard form. So:

y+1=-\frac{6}{15}x-2\\y+\frac{6}{15}x=-2-1\\y+\frac{6}{15}x=-3

<em>But A, B, and C (standard form) needs to be integers, so to get rid of the denominator , we multiply the whole equation by 15. So we have:</em>

y+\frac{6}{15}x=-3\\15y+6x=-45

<em>We can factor out a 3, so it becomes:</em>

15y+6x=-45\\5y+2x=-15

So standard form is 2x+5y=-15
