Answer:
- lesser x = -1.84
- lesser x = -8.16
Step-by-step explanation:
Given the expression
Add 10 to both sides
Simplify
solve
Subtract 5 from both sides
so
Subtract 5 from both sides
Simplify
As -1.84 > -8.16
so
- lesser x = -1.84
- lesser x = -8.16
<h3>
<u>Cookies</u></h3>
Rob: 3
Barry: 8
Kevin: 9
Let's add all of that up.
3 + 8 + 9
11 + 9
= 20 cookies total
<h3><u>
Milk</u></h3>
Rob: 2
Barry: 1
Kevin: 4
Let's add this up.
2 + 1 + 4
3 + 4
= 7 cups of milk
They had 20 cookies and 7 cups of milk before they ate.
Answer: (pi) (6 squared)
Step-by-step explanation:
Hi, the base area of a cone is a circle, so, to answer this question we have to apply the next formula:
Area of a circle: (pi) radius^2
The diameter (d) of a circle is equal to: 2 radius
So:
D = 2r
Replacing with the value given:
12 =2r
12/2=r
radius= 6 inches
Back with the Area formula:
A = (pi) 6^2
Feel free to ask for more if needed or if you did not understand something.
the 1 is the h and the -2 is the k
f(x) = a(x - h)^2 + k
f(x) = a(x-1)^2 -2
to find a substitute x=3, y=6 in
6= a(3-1)^2 -2
6 =a *2^2 -2
add 2 to each side
8 = 4a
a =2
f(x) = 2(x-1)^2 -2 this is the vertex form
distribute to get the standard from
f(x) = 2(x^2-2x+1) -2
2x^2 -4x+2-2
f(x) =2x^2-4x is the standard form
Choice A
