Answer:
The answer is "778"
Step-by-step explanation:
Given value:

The formula for z-score:
Vertex: V=(-2,-3)=(h,k)→h=-2, k=-3
The parabola is horizontal, then its equation has the form:
x=a(y-k)^2+h
x=a(y-(-3))^2+(-2)
x=a(y+3)^2-2
When the y-value is -2, the x-value is -5:
-5=a(-2+3)^2-2
-5=a(1)^2-2
-5=a(1)-2
-5=a-2
-5+2=a-2+2
-3=a
a=-3
Answer: The coefficient of the squared term in the parabola's equation is a=-3
Answer: Option D. -3
Answer:
x = -21.83 or (-21.83, 0)
Step-by-step explanation:
Use the given points to find the slope of the line.

(-9, -7) (13, -19)

Use the slope and one of the given points to solve the point-slope formula




Since you are looking for the x-intercept, set y=0 and solve for x



Answer:
5 quarters 12 dimes
Step-by-step explanation:
The quarters have to be a odd number or you wouldn't have the 5 at the end of the number. Because there are "two more then twice as many" dimes then quarters the number of quarters has to stay down. 3 to 5 is a good guess to start. from there you can add up the dimes until it all fits together
Answer:
56
Step-by-step explanation:
complementary angles are complement each other to 90
90-34=56
