Step-by-step explanation:
Hello hru
Answer:
A) x>4
Step-by-step explanation:
3x>12
Divide both sides by 3
x>4
Area of a circle = <span>πr^2
to find the radius we divide the diameter by 2
r = 8
</span><span>π=3
</span>
plug these values into your formula and solve
a=(3)(8)^2
a = 192m squared

Answer: 17</h3>
==================================================
Explanation:
We'll start things off by computing the inner function u(2)
Plug x = 2 into the u(x) function
u(x) = -x-1
u(2) = -2-1
u(2) = -3
This tells us that w(u(2)) is the same as w(-3). I replaced u(2) with -3.
We'll plug x = -3 into the w(x) function
w(x) = 2x^2-1
w(-3) = 2(-3)^2 - 1
w(-3) = 2(9) - 1
w(-3) = 18-1
w(-3) = 17
Therefore, w(u(2)) = 17
------------------------
Here's a slightly different approach:
Let's find what w(u(x)) is in general
w(x) = 2x^2 - 1
w(u(x)) = 2(u(x))^2 - 1
w(u(x)) = 2(-x-1)^2 - 1
Then we can plug in x = 2
w(u(x)) = 2(-x-1)^2 - 1
w(u(2)) = 2(-2-1)^2 - 1
w(u(2)) = 2(-3)^2 - 1
w(u(2)) = 2(9) - 1
w(u(2)) = 18 - 1
w(u(2)) = 17
Answer:480 grams
Step-by-step explanation:If one apple is 120 grams, four apples would be 480 grams (120 x 4 = 480)
