Answer:
Step-by-step explanation:
radius=4 as it is tangent to x-axis.
y co-ordinate of center is 4 so radius=4
eq. of circle is (x-2)²+(y-4)²=4²
or x²-4x+4+y²-8y+16=16
or x²+y²-4x-8y+4=0

Answer:
#1: -1
#2: 1
Step-by-step explanation:
Anything raised to the 0 power is 1, but in question 1 the negative is outside the parenthesis, so it makes it -1.
Answer:
d)1.08421 x 10^25 Kg
Step-by-step explanation:
The combined weight of these two bodies would be the addition of the masses of the two bodies.
Given that Earth weight is 5.9736 x 10^24 Kg and Venus is 4.8685 x 10^24 Kg,
The combined weight of Earth and Venus
= 5.9736 x 10^24 Kg + 4.8685 x 10^24 Kg
=10^24(5.9736 + 4.8685)
= 10.8421 × 10^24 Kg
In standard form,
= 1.08421 × 10^25 Kg
Well this is pretty simple
for the area we need to use the formula A=3.14*radius*radius
so we just plug it in and we get 3.14*8*8 which is 200.96 centimeters squared
for circumference we need to do C=3.14*diameter
to find the diamter we need to do 8 (radius) x 2 which is 16
plugging it in that would be 3.14 * 16 which is 50.24
So in this case the the area is 200.96 and the circumference is 50.24 :)
