Answer:
D) 20
Step-by-step explanation:
x^2 + (y - 2)^2=100
This can be rewritten as
(x-0)^2 + (y - 2)^2=10^2
This is in the form
(x-h)^2 + (y - k)^2=r^2
The radius is 10
The diameter is 2 times the radius
d = 2*r = 2*10 = 20
Answer:
4900
Step-by-step explanation:
4900
Step-by-step explanation:
=3x (2x+7)+2(2x+7)
=6x2+21x+4x+14
6x2+25x +14
Answer:
Without solving, the solution is greater than 21. The can be proven because a fraction of x is equal to 21, therefore x cannot be less than 21.
Step-by-step explanation:
The right question is that the lowest altitute is 3^8 feet
You are told that the highest altitude is 3 times the lowest altitude =>
highest altitude = 3 * lowest altitude = 3 * 3^8 feet.
Now you use the ruel of mutiplication of powers with the same base: copy the base and sum the exponents => 3 * 3^8 = 3 ^(1+8) = 3^9.
Note: remember that 3 = 3^1.
Answer: 3^9 feet
