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

Pls help me I’m struggling
Leni [432]

Answer:  Peter  < 65

Step-by-step explanation:   Peter has less than charlie so charlie is more than or/and equal to being solid line underneath or solid line on graph represented by ≥ 65 stays equal to 65 or more which is a<em> correct statement</em> for charlie as charlie cards are<em> increasing </em>at 65 and has 65 and Peter is shown as ≤ 65 but is slightly wrong as we were told in question that 'he has just started collecting' this means it has to be or certainly less than charlie has - Just in diagram is interpreted as a <em>dotted line on graph coordinates</em><em> </em>represented by < 65<em> instead IS LESS THAN 65</em> would be correct way to interprete inequality of<em> Peters relationship value </em>to that of charlie given amount

Help me on questions 8 through 12
mr_godi [17]
8. To find the answer you can eather multipy it for each of the sides or you can add it 6 times once for each side
15\frac{1}{4} \times 6 \\ \\ 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4}
9. You basicly do the same thing as the previous problem but with the new numbers and you add each number 2 times

10. For are you multiply Base × Height So all you have to do is Multiply the 2 numbers shown together
2 \frac{1}{2} \times 5
11-12 Is the same but witb the new numbers

I hope this helps!
