Answer:

Step-by-step explanation:

f(x) = 2x^2 - 4x + 5 Put brackets around the first 2 terms.

f(x) = (2x^2 - 4x) + 5 Take out the common factor of 2

f(x) = 2(x^2 - 2x) + 5 1/2 the second term and square.

f(x) = 2(x^2 -2x + (2/2)^2) + 5 Express brackets as a perfect square.

f(x) = 2(x - 1)^2 + 5 Multiply 2 * 1 (the term without an x. Subtract.

f(x) = 2(x - 1)^2 + 5 - 2 Combine

f(x) = 2(x - 1)^2 + 3

Kali has a 6 meter ladder that she wants to use to get her cat out of a tree. She puts the base of the ladder 2 meters away from

lara [203]

Answer:

The ladder will reach 5.6 meters high.

Step-by-step explanation:

The tree, the ground and Kali's ladder form a triangle whose hypotenuse $h$ is the ladder, base $b$ the ground, and perpendicular $p$ the tree. Thus from Pythagorean theorem:

$p^2+b^2=h^2$

Since $b=2$ and $h=6$

$p=\sqrt{h^2-b^2} =\sqrt{6^2-2^2}=\boxed{5.6\:meters.}$

Thus the ladder will reach 5.6 meters high.

50 POINTS!!!!! HELPFor the exponential function f(x)=a^x,a>0,a≠1 what is the domain? what is the range?

White raven [17]

I have included a graph to help you see what the domain and range would be
There are no minus y values.
0<y< infinity y is included in the reals.
The domain is
- infinity < x < infinity.

I don't want to say that either x or y can equal - or + infinity. Some teachers allow it. You have to ask your instructor what they will accept.

The blue line is y = 4^x
The red line is y = 2^x
