If (x) = x^2 - 3x + 1 what is the value of f(-2)

KIM [24]

Answer:

Step-by-step explanation:

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

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

f(-2) = 4 + 6 + 1

f(-2) = 11

Just substiute -2 for x and sove.

Write an equation of a line passing through the two points.

Anestetic [448]

To find the slope use Y2-Y1/X2-X1.
3-(-5)/1-(-3)
=8/4
=2
the slope of the line is 2.
m=2 plug into y=mx+b
use any set of coordinate points. ill use (1,3)
3=2(1)+b
b=1

SO YES YOU DID IT CORRECTLY!

What is the best approximation of the length of segment QS? (Note: cos 80° = 0.17)

LuckyWell [14K]

Answer:

Length of the segment QS = 11.76 cm

Step-by-step explanation:

We are given with right angle triangle QRS

Angle S is 80 degree and RS = 2 cm

We need to find out QS

RS is adjacent to angle S, so we use cos formula

$Cos (A) = \frac{adjacent}{hypotenuse}$

$Cos (S) = \frac{RS}{QS}$

Plug in the angle and RS

$Cos (80) = \frac{2}{QS}$

Given cos(80) = 0.17

$0.17= \frac{2}{QS}$

Multiply by QS on both sides

0.17 * QS = 2

Divide by 0.17 on both sides

QS= 11.76470588

Length of the segment QS = 11.76 cm
