1.6^2
It's telling you to multiply 1.6 by itself 2 times.
1.6 * 1.6 = 2.56
Range is ouput

basically see the vertices
y=a(x-h)^2+k
(h,k) is vertex
also, when a is negative, graph opens down
when a is positive, graph opens up
y<u><</u>5
k musbe 5
eliminate last 2
since less than, must open down
negative a
second one
f(x)=-(x-4)^2+5 is ansre
This creates a right triangle. One leg of the triangle is 25 feet and the other is 10 feet. To find the length of the ladder, we must use Pythagorean theorem.
a = 25
b = 10
c = ?
(25)^2 + (10)^2 = c^2. Square all the terms to the left of the equation and add them together.
725 = c^2. Take the square root of each side.
c = 26.93 feet.
The ladder needs to be 26.93 feet tall.
Answer:
2x²-2x
Step-by-step explanation:
To find the area of a rectangle, you multiply the sides together.
In this case:
x × 2x-2 = x(2x-2) = 2x²-2x
