Answer:

C = 90°

Step-by-step explanation:

The interior angles in every triangle are equal to 180 degrees. So, this means that

$\alpha + \beta + \gamma \\ = 180 \: degrees$

Which means that A + B +C = 180 degrees

A=25°

B = 65°

C =?

C = 180° - (A + B)

C = 180° - (25° +65°)

C = 180° - 90°

C = 90°

Answer:

cos 25° = X/11

and

sin 65° = X/11

is this good enough or do you need more workings?

60 PTS [see image] "Identify the parent function that can be used to graph the function"

skelet666 [1.2K]

Answer:

The parent is x^2

Step-by-step explanation:

We are shifting the function and stretching the function

The parent function is x^2

f(x) = x^2

Then shift

f(x) = (x-9)^2

Then stretch

3 (x-9)^2

Answer:

$y+2=-\frac{3}{2}(x-2)$

Step-by-step explanation:

Given:

Two points on a line are given as:

(0, 1) and (2, -2)

We know that the slope of a line passing through points $(x_1,y_1)\ and\ (x_2,y_2)$ is given as:

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in $x_1=0,y_1=1,x_2=2,y_2=-2$ . This gives,

$m=\frac{-2-1}{2-0}\\\\m=\frac{-3}{2}=-\frac{3}{2}$

The equation of a line with slope 'm' and points $(x_1,y_1)\ and\ (x_2,y_2)$ is given as:

$y-y_1=m(x-x_1)\\\\or\\\\y-y_2=m(x-x_2)$

Now, on plugging in the second point $(x_2,y_2)=(2,-2)$ we get:

$y-(-2)=-\frac{3}{2}(x-2)\\\\y+2=-\frac{3}{2}(x-2)$

Therefore, the first option is correct which is given as:

$y+2=-\frac{3}{2}(x-2)$

Answer in Slope intercept form

ololo11 [35]

Answer:

y=3x-6

Step-by-step explanation:

if the y int is (0,-6),

b in the equation y=mx+b is -6

if the slope is 3, m in the equation y=mx+b is 3

so, the equation is y=3x-6
