<span>Students are given two arrays, one representing the equation 7 x 9 = 63 and the other representing the equation (5 + 2) x 9 = 63, to see if they recognize a relationship between the two.

A college student borrows $2,000 for 9 months to pay for a semester of school. If the interest is $123.75, find the monthly paym

juin [17]

Total amount borrowed by college student = $ 2,000

Total interest paid = $123.75

Total amount the student has to pay = $2,000 + $123.75

= $2123.75

Total duration for which the amount is borrowed = 9 months

Total amount he has to pay back in 1 month = $$2123.75 \div 9$

= $235.9

Therefore, Amount he has to pay in 1 month = $235.9

Find the equation of the sphere in standard form centered at (−6,10,5) with radius 5.

Dovator [93]

Answer:

The equation of the sphere in standard form is

$x^{2} +y^{2}+z^{2} +12 x-20 y-10 z+136=0$

Step-by-step explanation:

<u>Step 1</u>:-

The equation of the sphere having center and radius is

$(x-h)^{2} +(y-k)^{2} +(z-l)^{2} = r^{2}$

Given centered of the sphere is (-6,10,5) and radius r=5

$(x-(-6))^{2} +(y-10)^{2} +(z-5)^{2} = 5^{2}$

on simplification,we get

$using (a+b)^{2} =a^{2} +2 a b+b^{2}$

$using (a-b)^{2} =a^{2} -2 a b+b^{2}$

simplify , we get

$x^{2} +y^{2}+z^{2} +12 x-20 y-10 z+136=0$
