A. identify the vertex
B. Identify the intercept
C. Write the equation of the graph above
D. Fill in the end behavior:
As x , y ____
As x 3, y ____
E. Identify the domain and range:
We want to identify different things on the given graph.
The solutions are:
A) (3, -1)
B) x = 4
C) x = y^2 + 2y + 4
D) x ⇒ ∞, y ⇒ ∞
x⇒3, y⇒ -1
A) The first thing we want to identify is the vertex, we could say that a vertex is a point of symmetry. (like the minimum/maximum of a parabola). Here we clearly do not have a point of symmetry, as we only have half of a parabola, but if it was a complete one, the vertex would be at the blue point, in (3, -1)
B) This is the point where the graph intercepts the x-axis, x = 4.
C) we want to write the equation, we start with the general parabola, this time as a function of y:
x = a*y^2 + b*y + c
Remember that the x-itercept is at x = 4. then c = 4.
x = a*y^2 + b*y + 4
The y-value of the vertex is -1, while the general y-value of the vertex is:
y = -b/2a = -1
And evaluating the equation in this value, gives us:
x = a*(-1)^2 + b*-1 + 4 = 3
Then we have two equations:
-b/2a = -1
a + -b + 4 = 3
We can rewrite the first one as:
-b = -2a
b = 2a
Now we can replace this on the other equation:
a - 2a + 4 =3
-a + 4 = 3
-a = 3 - 4 = -1
a = 1
And b = 2a = 2*1 = 2
Then the equation of the parabola is:
x = y^2 + 2y + 4
D) We can see that as x grows, y increases, so we can say that:
x ⇒ ∞, y ⇒ ∞
And for the other limit we can see that as x tends to 3, y tends to -1, then:
x⇒3, y⇒ -1

A rocket needs to reach a speed of 28,300 km/hr in order to get into orbit around Earth. How fast is this in miles per second.
Answer:
Step-by-step explanation:
1 km = 0. 621371 miles
28,300 km = 28,300* 0. 621371 miles = 17,584.7993 miles
1 hour = 60 *60 seconds = 3,600 seconds
speed of 28,300 km/hr =
17,584.7993 miles / 3,600 seconds ≈ 4.88 miles / second

Answer:
350
Step-by-step explanation:
Multiply all the sides by each other. This is a triangular prism so the base, you divide by 1/2. So:
A = 7 * 10 * 10
A= 7 * 5 * 10.
(You divide the ten on the bottom)
7*5 = 35
35*10 = 350
Answer:
240
Step-by-step explanation:
The surface is the sum of the sides (all 4 equal) plus the base.
A = 4(1/2B * H) + B**2
A = 4((1/2 * 10) * 7) + 10 * 10
A = 4(5 * 7) + 100
A = 4 * 35 + 100
A = 140 + 100
A = 240

Refer to Exhibit 11-4. If a person's taxable income is $50,000, how much does he pay in taxes?
$9,250
$10,110
O $15,000
O $12,500
Based on the exhibit attached, we can calculate that a person earning $50,000 will pay $9,250.
People earning $50,000 fall into the $42,001 - $100,000 bracket which means that they pay $7,250 + 25% of everything over $42,000.
The amount of taxes is:
= 7,250 + ( 25% x (50,000 - 42,000))
= 7,250 + (25% x 8,000)
= $9,250
In conclusion, the person would pay $9,250 in taxes.

h(-3) means that we put the argument (-3) into the formula of the function everywhere where there is x.
h(x) = -3x - 10
so,
h(-3) = -3×-3 - 10 = 9 - 10 = -1
Answer:
-1
Step-by-step explanation:
h(x) = -3x - 10
h(-3) means to replace the x in the problem with the value of -3 and
solve.
h(-3) = -3(-3) - 10
h(-3) = 9 - 10
h(3) = -1
George walked 6 miles in 2 hours.
What was his average walking rate in miles per hour?
2 miles per hour
3 miles per hour
4 miles per hour
Answer:
3 miles per hour
Step-by-step explanation:
Well, what we do in these situations is simple. We divide.
So this George guy, he walks six miles in 2 hours.
I think to myself, "Okay, so that's 6 divided by 2."
So, we get 3.
#It'sNotRocketScience
if George walked 6 miles in 2 hours. Then his average walking rate in miles per hour is 3 miles per hour
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
George walked 6 miles in 2 hours.
We need to find his average walking rate in miles per hour
Let x be the average walking rate in miles per hour
Let us form an equation
miles/hour----->6/2=x/1
3=x
So the value of x is 3
Hence if George walked 6 miles in 2 hours. Then his average walking rate in miles per hour is 3 miles per hour

Kylie is excited to learn how to ski. She went to Snowy Heights Mountain, rented a pair of skis for $35, and took 5 hours of group skiing lessons. Kylie paid $175 in all. How much does Snowy Heights charge for each hour of group skiing lessons?
Answer:
5x + 35 = 175
$28
Step-by-step explanation:
She paid 35 for 1 pair of skis. She paid a certain amount(x) for 5 hours (5x + 35). Therefor making the expression 5x + 35 = 175.
Then, solve the equation with inverse operations.
5x + 35 = 175
Step 1: Subtract 35 from both sides.
5x = 140
Step 2: Divide 5 from both sides.
x = 28
Therefore, Kylie paid $28 each hour of the group skiing lessons.

a) as it's an Isosceles triangle so both the given sides are equal
so, a/q
→ 7x - 4 = 24
→ 7x = 24 + 4 = 28
→ x = 28/7 = 4
→ x = 4
therefore, value of x is 4.
b) 4y + 4 = y + 16
→ 4y - y = 16 - 4
→ 3y = 12
→ y = 12/3 = 4
→ y = 4
