PRECALCULUS QUESTION PLEASE HELP!!!!!!

1 answer:

4 0

Some information is missing for #6.
#7: use sine, sin35=h/5.1, h=5.1*sin35, use a calculator, h≈2.9
#23: to find the reference angle, keep subtracting the number by 360, until the remaining difference is the smallest positive number.
1406-360-360-360=326. the reference angle is 326.
now look at the remainder, the terminal line of 326 degree is in the 4th quadrant between 270 and 360, the the reference angle is 360-326=34, the angle between the terminal line and the positive x axis. 34 is the answer.

For a given function ƒ(x) = x2 – x + 1, the operation –ƒ(x) = –(x2 – x + 1) will result in a

Mekhanik [1.2K]

Given:

The function is:

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

To find:

The result of the operation $-f(x)=-(x^2-x+1)$ .

Solution:

If $g(x)=-f(x)$ , then the graph of f(x) is reflected across the x-axis to get the graph of g(x).

We have,

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

The given operation is:

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

So, it will result in a reflection across the x-axis.

Therefore, the correct option is A.

What are the coordinates of the vertex of y = –x2 – 12x – 32?

LekaFEV [45]

Answer:

x^2=12x-32

Step-by-step explanation:

try to factor by splitting the middle term example x^2-(12*x-32)=0

multiply the coefficient of the first term by the the constant 1 X 32=32

find two factors of 32 whose sum equals the coefficient of the middle term which is answer keys -32 +-1 =-33

-16+-2=-18

-8+4=-12.
