cost = 2*3.07+10.36
cost = 6.14+10.36
cost =16.50
20-16.50=change
3.50
She will get $3.50 change
Yea so the lowest is y=-4 and the highest is y=7.5
X^2 + 10x + c
Use the number in front of x, (10), to help you.
First, divide 10 by 2:
10/2 = 5
Second, square the answer, (5).
(x+5)(x+5) = 25
Answer: c=+25
Answer: 60 degrees
Step-by-step explanation:
1. Make a right triangle where the right angle is and label the hypotenuse r.
2. Since the chord is equal to r and a 90-degree angle is formed at the intersection, the chord is bisected. Therefore, the chord segment is 1/2 r.
3. Since we have to solve for the intercepted arc, we must find the central angle ( the angle of the right triangle closest to the dot/center) of the arc, which in this case is the sin, or 0.5r/r.
4. We must get rid of the fraction in the numerator, so multiply both the numerator and denominator by 2 which gets you 1r/2r.
5. The r's cancel out, leaving you with 1/2.
6. Since we have to find the angle measure, you must take the negative sin of 1/2 which is 30 degrees.
7. Finally multiply by 2 since you only solved one bisected portion to get 60 degrees.
Non-proportional because all the dots are scattered I believe a proportional chart will have a straight line please correct me if I’m wrong :)
