Answer:
x = 5
Step-by-step explanation:
The length of line segments joining a common point to tangents are always equal.
RS = RQ = 2
PW = PQ = 3
x = PQ + QR = 3 + 2 = 5
Answer:
zachary
Step-by-step explanation:
the shorter the time the faster
Using the equation, the amount of ribbon she needs to sell to break even is 50 ribbons.
<h3>How to represent system of equation and solve?</h3>
x = number of ribbons
y = expenses or revenue
Therefore, the system of equation for this situation is as follows;
y(expenses) = 23 + 0.04x
y = 23 + 0.04x
He charges $0.50 per ribbon. Therefore,
y(revenue) = 0.50x
y = 0.50x
Therefore, for her to break even,
23 + 0.04x = 0.50x
23 = 0.46x
x = 23 / 0.46
x = 50
Therefore, she needs to sell 50 ribbons for her to break even.

Answer:
The toy's maximum height is 
.
Step-by-step explanation:
The equation that models the toy's height in feet from the ground at t seconds after he threw it is given by :
.....(1)
It is required to find the toy's maximum height. For maxima or minima, put
Plugging the value of t in above equation,
Now put t = 1.75 s in equation (1) such that,
So, the toy's maximum height is .
