Answer:
a) 24 cm
Step-by-step explanation:
Tangents form a 90° angle with a radius.
using the Pythagorean theorem:
D² = 25² - 7²
D² = 625 - 49 = 576
D = 24
He would have to pay $100. A 25% tip equals to $20 so add that to the original bill and you get $100. Hope this helped!
Answer: y=4x-3
Step-by-step explanation:
point slope form is y-y1=m(x-x1)
y-1=(4)(x-1)
y-1=4x-4
y=4x-3
A vertical line is perpendicular to the x-axis because they would intersect to form a 90 degree angle.
