Answer:
BAD = 64°
Step-by-step explanation:
ADE = (180-52):2 = 64°
ED || AB => ADE = BAD = 64°
Answer:
additive inverse of
Step-by-step explanation:
Additive inverse of any number is that number added to the given number result into zero. For example a is an additive inverse of -a because a+(-a) = a-a = 0
According to the question, -4 and 4 are additive inverse of each other. Hence -4 is the additive inverse of 4
Answer: The parabola has its concavity downwards, so we need a function in the model:
With a negative value of 'a'
The vertex is (0,0), so we have that:
The x-coordinate of the vertex is given by the equation:
So we have a function in the model:
With a < 0
The only option with this format is B:
Step-by-step explanation:
Answer:
a. 8.5 in.
b. 34 in
c. x = 1/39 x^2.
Step-by-step explanation:
Part a.
x = 1/34 y^2
y^2 = 34x
Comparing with y^2 = 4px where p is the focus:
4p = 34
p = 8.5 in.
Part b.
The diameter = 4p = 34 in.
Part c.
Diameter = 4p = 34 + 5 = 39 in
The new equation is x = 1/39 x^2.
