Answer:
1 2/5 -Your friend, Bill Cipher
Step-by-step explanation:
Venus is a planet, hence is spherical shaped.
Formula for Volume of a Sphere: 4/3πr^2
Apply this formula
4/3π(3760.4)^2=59232040.95 miles^3
Answer:
k = 16 , (4, 0 )
Step-by-step explanation:
Using the discriminant Δ = b² - 4ac
• b² - 4ac = 0 , then 2 real and equal roots
Here
y = x² - 8x + k
with a = 1, b = - 8, c = k , then
b² - 4ac
= (- 8)² - (4 × 1 × k)
= 64 - 4k , and equating to zero
64 - 4k = 0 ( subtract 64 from both sides )
- 4k = - 64 ( divide both sides by - 4 )
k = 16
Then
y = x² - 8x + 16
Equate to zero to find the root
x² - 8x + 16 = 0 ← left side is a perfect square
(x - 4)² = 0
x - 4 = 0 ( add 4 to both sides )
x = 4
The point on the x- axis is (4, 0 )
Answer:
5
Step-by-step explanation:
<u>move constant</u>
x+7 ≥ 12
<u>subtract</u>
x≥ 12-7
<u>solution</u>
x ≥ 5
Diide both sides by -1
|j|=9
rememeber if |a|=b, then assume a=b and a=-b
so
j=9 and j=-9
