Answer:
C. 50
Step-by-step explanation:
The triangles are proportional and that is why you can find the scale factor. Set up a proportion (equivalent fractions). Set the proportion up with the corresponding sides together on thee top or the bottom of the proportion.
<u>65 </u> = <u> 91</u>
x 70
91x = 65 * 70
<u>91x</u> = <u>4550</u>
91 91
x = 50
1.06418
The same as of sec 20 degrees in radians to obtain 20 degrees in radian multiply 20° by / 180° = 1/9
standard form: 10x - y = 0
Use the slope-intercept form to find the slope and y-intercept.
Slope: 10
y-intercept: (0, 0)
2b) stretching
2c) it is stretched by a factor of 2 of the parent function f(x)=x
