Step-by-step explanation:
Answer:
y = 11.54°
Step-by-step explanation:
Reference angle = y°
Opposite side length = 4
Hypotenuse = 20
Apply trigonometric function SOH:
y = 11.536959° ≈ 11.54° (nearest hundredth)
200 min / $10.00 = 20 minutes / dollar
<span>300 min / $12.00 = 25 minutes / dollar </span>
<span>The cost of the 300 minute card is cheaper per minute and a better value. </span>
<span>If you don't expect to use more than 200 minutes then save your money and buy the smaller card.</span>
Answer:
y = 5/7 x - 6
Step-by-step explanation:
For two lines to be perpendicular, the product of their slope must be -1
The slope of the given function is -7/5
Let the slope of the required function be m
m * -7/5 = -1
7/5 m = 1
7 = 5m
m = 5/7
The slope of the line perpendicular to the line is 5/7
The required equation (using any value of the y-intercept) is expressed as;
y = 5/7 x - 6
Note that the y-intercept value was assumed and any value can be used
