What connection exists between the coordinates of the vertex and the equation of the axis symmetry

The vertex of a parabola is the maximum or minimum value, and it’s represented by (x,y). The axis of symmetry is the vertical line that runs through the x axis, and also runs through the vertex. This means that the x value in the vertex (x,y) can represent the axis of symmetry.

Solve for x<br> x= ?<br> 3x-4 3x-8

Musya8 [376]

Answer:

x = 32

Step-by-step explanation:

=> (3x-4) + (3x-8) = 180° (Linear pair)

=> 6x - 12 = 180

=> 6x = 192

=> x = 192/6

Therefore <u>x = 32</u>

The answer is D. 60'. You add both angles together, then subtract them from 180.
60+70=120
180-120=60

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
