Emili would like to estimate the probability of 2 or more heads coming up in 3 coin flips.

The parking rates at the hospital’s parking garage are 50 cents for the first hour and 25 cents for each additional hour. If Jua

Bad White [126]

The total charge for Juan in the parking spot would be $2.25.

Since we know one of those 8 hours is 50 cents, we can multiply .25 by 7 which would give us 1.75. Then we know that the first hour, as stated above, is going to be .50, so we can add that to our total which is 2.25.

Hope this helps!

Need help and will be giving Brainliest

Katena32 [7]

Answer:

x-intercept (s):

For this case h (x) = 0

x2 - 2x - 8 = 0

(x-4) * (x + 2) = 0

x1 = 4

x2 = -2

y-intercept:

For this case x = 0

h (0) = (0)2 - 2 (0) - 8

h (0) = - 8

vertex:

We derive the equation:

h '(x) = x2 - 2x - 8

h (x) = 2x - 2

We match zero:

2x-2 = 0

x = 2/2

x = 1

We evaluate the function for x = 1

h (1) = (1)2 - 2 (1) - 8

h (1) = 1 - 2 - 8

h (1) = -9

The vertex is:

(1, -9)

axis of symmetry of the function:

x = 1

Step-by-step explanation:

How do you Identify and contrast the differences between the rise in prices due to inflation and the rise in prices in microecon

andrezito [222]

One can Identify the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets by?

Observing the trends in prices.
Observing Demand and supply curve.

<h3>Contrast the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets.</h3>

The difference that exist between a rise in price due to the inflation and a rise in price due to microeconomic markets is based on the price changes that has occurred in terms of demand and supply model.

Note that this is said to be the price in a given market but the price rise as a result of to inflation tells that the price rise is one that reaches a lot of markets and not only just one market.

Hence, One can Identify the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets by?

Observing the trends in prices.
Observing Demand and supply curve.

1. The equation of a parabola is given.

svp [43]

Question 1)

The given parabola is:

$y= \frac{1}{8} x^{2} +4x+20$

First we need to convert this equation to the general form similar to:

$4p(y-k)=(x-h)^{2}$

So, the given equation will be:

$y= \frac{1}{8} x^{2} +4x+20 \\ \\ 
y= \frac{1}{8}( x^{2} +32x)+20 \\ \\ 
y= \frac{1}{8}( x^{2} +32x+256)+20- \frac{1}{8}(256) \\ \\ 
y = \frac{1}{8}(x+16)^{2}-12 \\ \\ 
y+12= \frac{1}{8}(x+16)^{2} \\ \\ 
8(y+12)=(x+16)^{2} \\ \\ 
4*2(y-(-12))=(x-(-16))^{2}$

Comparing given equation with the general equation, we can write:
p = 2
h = -12
k= -16

The focus of the parabola with squared x terms lies at (h , k+p)
Using the values, we get the focus point of the given parabola (-16, -10)

Question 2.

The equation of the parabola is:
$(y-1)^{2}=16(x+3) \\ \\ 
(y-1)^{2}=4*4(x+3)$

This means:
p=4
h = -3
k =1

The directrix of the parabola with squared y term has the equation of the form:

x = h - p

Using the values, we get

x= - 3 - 4 = -7

So, the equation of the directrix of the parabola will be x = -7
