Answer and Step-by-step explanation:

The answer is the last answer choice.

g(x) = [tex]-(x + 2)^2 + 1[/tex]

We don't even have to look at the numbers to tell that this is the correct answer. We look at what is being placed there.

The equation for a transformed function is:

f(x) = [tex]a(x-h)^2 + k[/tex]

a determines the scale of the graph and whether the graph opens up or down.

h determines whether the graph shifts left or right.

k determines whether the graph shifts up or down.

We see that there is a -1 for a, which means the graph will be facing downwards. We see a 2 for where h is, but it really is a -2, and when it becomes a positive after simplifying, the graph will shift to the left.

k is a positive 1, so the graph will be shifted up 1 unit.

Thus, the answer is the last answer choice.

Answer:

The center of the circle is point: C=(1,5).

The radius of the circle is r=3.

Step-by-step explanation:

x² + y² -2x - 10y + 17 = 0

Find the center and radius of this circle

We have the equation

x² + y² -2x - 10y + 17 = 0

We collect like terms

x² - 2x + y² - 10y = -17

x² - 2x + (-2/2)² + y² - 10y + (-10/2)² = -17 + (-2/2)² + (-10/2)²

The center of the circle is point: C=(1,5).

The radius of the circle is r=3.

Brian rolls a fair dice 12 times. How many times would Brian expect to roll a number greater than 4?

Answers

Brian is expected to roll a number greater than 4, 4 times

How to determine the expected row?

In a fair die, we have:

Faces = 6

Faces greater than 4 = 2 i.e. 5 and 6

So, the probability to roll a number greater than 4 is:

p = 2/6

When the dice is rolled 12 times, the expected value is:

Expected = 2/6 * 12

Evaluate

Expected = 4

Hence, Brian is expected to roll a number greater than 4, 4 times

On a particular flight, the airline's income was $95,280 for a jumbo jet carrying 290 passengers. If a first-class ticket costs $680 and a coach ticket costs $288, how many of each ticket were sold for the flight?

Answers

Answer:

30 first-class tickets were sold and 260 coach tickets were sold.

Step-by-step explanation:

Let a first-class ticket be represented by f and let a coach ticket be represented by c.

On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:

[tex]f+c=290[/tex]

The total income was $95,280. Therefore:

[tex]680f+288c=95280[/tex]

We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:

[tex]85f+36c=11910[/tex]

From the first equation, we can subtract f from both sides:

[tex]c=290-f[/tex]

Substitute:

[tex]85f+36(290-f)=11910[/tex]

Distribute:

[tex]85f+10440-36f=11910[/tex]

Simplify:

[tex]49f=1470[/tex]

So:

[tex]f=30[/tex]

From the previous equation:

[tex]c=290-f[/tex]

Substitute:

[tex]c=290-30=260[/tex]

30 first-class tickets were sold and 260 coach tickets were sold.

A.72.75
B.76
C.89.5
D.97

Pls help TT

Answers

Answer:

total points on the 4 tests- 94x4= 376

376- 85= 291

291/3= D. 97

Answer:

D. 97

Step-by-step explanation:

x = sum of 4 test grades Jared received

[tex]\frac{x}{4} = 94[/tex]

x = 376

If he drops lowest test grade of 85, then subtract 85 from Jared's sum of all test grades:

x - 85 --> 376 - 85

= 291

Now that one of his test grades are not considered, this means there are only 3 test grades to consider.

291 must be divided by 3 to get the average:

[tex]\frac{291}{3}[/tex] = 97

The answer is D) 97

A package of mixed lettuce seeds contains 150 green lettuce seeds and 50 red lettuce seeds. What is the probability that a randomly selected seed will be a red lettuce seed? Write your answer as a percent.​

Answers

Answer:

25%

Step-by-step explanation:

I used relative frequency approach

n(total number of seeds)= 150+50=200.

probability (selecting a red lettuce) = red lettuce divided by the total number of seeds.

probability (selecting red lettuce) = 50/200 = 0.25

in percentage, probability = 0.25*100= 25%✓

richard klein works as auto mechanic and earns the following commission rates 3.00 percent for oil changes 5.00 percent for tune ups and 6.25 percent on auto parts sales he is guaranteed a minimum salary of $2,450.00 per month last month he brought in $2,500.00 in oil changes $4,500.00 in tune ups and sold $28,200.00 in parts what is his gross pay for the month

Answers

Answer:

His gross pay for the month is $4,509.50

Step-by-step explanation:

The commission Richard Klein earns for oil change = 3.00%

The commission he earns for tune ups = 5.00%

The commission he earns for auto parts sales = 6.25%

The minimum salary he is guaranteed = $2,450.00

The amount he brought in last month includes;

1) $2,500.00 in oil changes

2) $4,500 in tune ups

3) Sold $28,200.00 in parts

The amount he earns last month in commission are;

3/100 × 2,500 = 75 in oil changes

5/100 × 4,500 = 225 in tune ups

6.25/100 × 28,200 = 1762.5 in parts sold

The total commission = 72 + 225 + 1762.5 = 2,059.5

∴ The total commission = $2,059.5

The amount he makes as salary = $2,450.00

Richard Klein's gross pay for the month = His total pay for the month

Therefore;

Richard Klein's gross pay for the month = $2,059.5 + $2,450 = $4,509.5

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 20 yards of carpet weighs 30 pounds.

Here, 1 yard of carpet weighs = 30/20

= 1.5 pounds

34 yards of carpet weighs

= 34×1.5

= 51 pounds

Therefore, 34 yards of carpet weighs 51 pounds.

The regular price of a video game is $59.95 and we are told that this week it is on sale for 15% off.

The game cost this week before taxes will be:

= 59.95 - (15% × 59.95)

= 59.95 - (0.15 × 59.95)

= 59.95 - 8.9925

= $50.9575

The amount this week is $50.96
