The graph of r = -10 cos θ has which of the following characteristics?

Ronch [10]

Step-by-step explanation:

If we convert

$r = - 10 \cos(x)$

to a Cartesian equation,

${r}^{2} = - 10 r \: \cos(x)$

${x}^{2} + {y}^{2} = - 10x$

${x}^{2} + 10x + {y}^{2} = 0$

${x}^{2} + 10x + 25 + {y}^{2} = 25$

$(x + 5) {}^{2} + {y}^{2} = 25$

So we have a circle with center (-5,0), with a diameter of 10.

What is the least perfect square which is divisible by 24 30 and 60?

yanalaym [24]

Step 1: LCM of 24 , 30 and 60 = 120

so 120 is the least no which is divisible by all 24 , 30 and 60

Step 2: factors of 120 will be 2^3 * 3 * 5

so the least perfect square, which is divisible by 24, 30 and 60 will be
(2^3 * 3 * 5) x ( 2 * 3 * 5 ) = 3600

3600

Solve this equation please 15-5(4c-7)=50

WITCHER [35]

Answer:

not sure but i think c=12

15-5=10

10x4c-7=50

10× 4c-7/4=50

10×(c-7)=50

10c-7=50

10c/10=50/10

c-7/7 =5

c=5+7=12
