Find an equation of the sphere with center (4, −12, 8) and radius 10.

Lorico [155]

Answer:

Step-by-step explanation:

To find an equation of the sphere with center (4, −12, 8) and radius 10

$(x-4)^2+(y+12)^2+(z-8)^2 = 100$

intersection with xy-plane

Put z=0

$(x-4)^2+(y+12)^2+(0-8)^2 = 100$

$(x-4)^2+(y+12)^2 = 36$

(A circle with centre at (4,-12) and radius 6)

intersection with xz-plane

Put y =0

$(x-4)^2+(0+12)^2+(z-8)^2 = 100$

$(x-4)^2+(z-8)^2 = -44$

Sum of squares cannot be positive, so DNE

intersection with yz-plane

Put x=0

$(0-4)^2+(y+12)^2+(z-8)^2 = 100$

$(y+12)^2+(z-8)^2 = 84$

A circle in YZ plane with centre at y =-12 and z =8 and radius square root of 84

Need help ASAP I’m about to go to sleep

Arlecino [84]

Answer:

A. $1852.50

Step-by-step explanation:

Principal amount= P= $3, 900

Rate= r = 19% = 0.19

Time (in years) = t = 2.5

<u>Amount after 2.5 years (A)</u>

$A = P(1+r t )$

$A = 3900 (1+ (0.19) 2.5)$

$A = 5,752.5$

Total interest in 2.5 years = A-P = 5752.5 - 3900 = 1852.50
