Find the range of the function.

1 answer:

5 0

The vertex form of a quadratic function is given by
$f(x)=a (x-h)^{2} +k$ , where (h, k) is the vertex of the equation.
In the given function, (h, k) = (2, 2), also a = 1 which is positive, this means that the parabola is facing up, hence the range is given by y ≥ k.
Therefore, range is y ≥ 2.

Answer:

angle DEG=47+30(sum of two interior opposite angle is equal to the exterior angle formed)

DEG=77 degree

DEF+47+30=180(being sum of interior angle of a triangle)

DEF+77=180

DEF=180-77

DEF=103 degree

measure of each angle is 60 degree

Doug earns $10.50 per hour working at a restaurant. On

alexira [117]

First, add all of the working hours.
1 $\frac{3}{4}$ + 2 $\frac{1}{3}$ + 1 $\frac{5}{12}$

Since the denominators are different, make them all the same.
1 $\frac{9}{12}$ + 2 $\frac{4}{12}$ + 1 $\frac{5}{12}$

Add everything together.
4 $\frac{1}{12}$ + 1 $\frac{5}{12}$ = 5 $\frac{6}{12}$

Then, simplify.
5 $\frac{1}{2}$ or 5.5

Multiply the time by the salary.
5.5*10.5= Doug earned $57.75

It has been estimated that the price elasticity of demand for attending baseball games is 0.23. Other things held constant, a 10

Akimi4 [234]

Answer:

Correct option: (A) 43.48% fall in the price of a ticket.

Step-by-step explanation:

The price elasticity of demand is defined as the percent change in quantity demanded to the percent change in the price.

$Price\ elasticity\ of\ demand=\frac{\%\ change\ in\ quantity\ demanded}{\%\ change\ in\ price}$

Given:

Price elasticity of demand = 0.23

% change in quantity demanded = 10

Compute the % change in price as follows:

$Price\ elasticity\ of\ demand=\frac{\%\ change\ in\ quantity\ demanded}{\%\ change\ in\ price}\\0.23=\frac{10}{\%\ change\ in\ price}\\{\%\ change\ in\ price}=\frac{10}{0.23}\\=43.4783\\\approx43.48$

Thus, a 10 percent increase in attendance can be explained by a 43.48% fall in the price of a ticket.

ASAP!!!!!! Y-9=4(X+2)

Artemon [7]

SimplifyingY + -9 = 4(x + -2)
Reorder the terms:-9 + Y = 4(x + -2)
Reorder the terms:-9 + Y = 4(-2 + x)-9 + Y = (-2 * 4 + x * 4)-9 + Y = (-8 + 4x)
Solving-9 + Y = -8 + 4x
Solving for variable 'Y'.
Move all terms containing Y to the left, all other terms to the right.
Add '9' to each side of the equation.-9 + 9 + Y = -8 + 9 + 4x
Combine like terms: -9 + 9 = 00 + Y = -8 + 9 + 4xY = -8 + 9 + 4x
Combine like terms: -8 + 9 = 1Y = 1 + 4x
SimplifyingY = 1 + 4x
