What Is The Equation Of This Parabola?

Answers

Answer 1

Answer:

y = - x² + 4

Step-by-step explanation:

The equation of a parabola whose vertex is on the y- axis is

y = ax² + c

where a is a multiplier and c is the y- intercept

• If a > 0 then minimum vertex

• If a < 0 then maximum vertex

Here vertex is a max, thus a = - 1 and c = 4

Then equation of parabola is

y = - x² + 4

Martin is seating people in the cars of a roller coaster. Each car can seat 8 people. Six of the roller coaster cars are yellow and nine of the roller coaster cars are green. People will be randomly seated in the roller coaster cars. What is the probability that the first person will be seated in a yellow roller coaster car?

Answers

Answer:

The probability is 2/5

Step-by-step explanation:

Here, we want to calculate the probability that the first person will sit in a yellow roller coaster car

The number of cars to select from is 6 + 9 = 15 cars

The number of yellow cars is 6

So the probability that the first person selects a yellow roller coaster car to seat is 6/15 = 2/5

Answers

Answer:

x=14

Step-by-step explanation:

Solving the equation x - 10 = 4, the value of x, which is the solution is calculated as x = 14.

How to Solve an Equation?

Solving an equation simply involves determining the value of the variable in the equation, which is the unknown.

For example, we are asked to solve the equation, x - 10 = 4., what it simply means is that we need to determine what the value of x is in the equation that will make it true. Do the following:

x - 10 = 4

x - 10 + 10 = 4+ 10 [addition property of equality]

x = 14

Therefore, the solution of the equation is x = 14.

[tex]\huge\boxed{\sf Star = 14}[/tex]

Step-by-step explanation:

Let snowman be x , star be y and shopping bag be z.

So, the given equations are:

1) x + y = 20                 (Eq. 1)

2) z = x + x      

 z = 2x                         (Eq. 2)

3) z + x = 18                   (Eq. 3)

Put Eq. (2) in Eq. (3)

2x + x = 18

3x = 18

Divide both sides by 3

x = 18 / 3

x = snowman = 6

Now, Put x in (Eq. 1)

6 + y = 20

Subtract 6 to both sides

y = 20 - 6

y = 14

So,

Star = 14

What is the base area.

Answers

Answer:

Area of the base is 10.5 cm².

Step-by-step explanation:

Formula for the volume of the given oblique prism = Area of the triangular base × Vertical height between two triangular bases

Vertical height = 6 cm

Volume = 63 cm³

From the formula,

63 = Area of the triangular base × 6

Area of the base = [tex]\frac{63}{6}[/tex]

                            = 10.5 cm²

Therefore, area of the base is 10.5 cm².

please can anyone help me solve those questions with explanation thank you!!!​

Answers

Step-by-step explanation:

A: X=4

Step 1: Distribute the 7 within the parenthesis which will give you:

7x - 21 = 7

Step 2: Add over the -21 to the other side of the = which will give you:

7x = 28

Step 3: Divide by 7 on both sides to get the final answer, X=4

B: M=9

Step 1: Multiply by 4 on both sides, to cancel it out on the right, which will give you:

32 = 3m + 5

Step 2: Subtract the 5 from each side, giving you:

27 = 3m

Step 3: Divide by 3 on both sides to get the final answer, M=9

C: X=28

Step 1: Subtract 9 from both sides, giving you:

x/2 = 14

Step 2: Multiply by 2 on both sides to give you:

x = 28  (This will be our final answer, there is nothing left to simplify.)

D: X=3

Step 1: Distribute the 2 on the left and the (-) on the right to give you:

5 + 2x + 10 = 10 - 4 + 5x

Step 2: Combine like terms and simplify to give you:

15 + 2x = 6 + 5x

Step 3: Subtract over the (2x) to give you:

15 = 6 + 3x

Step 4: Subtract over the 6 to give you:

9 = 3x

Step 5: Divide by 3 on both sides to get the final answer, X=3

Rebecca runs a quarter-mile each week. In each of the last 6 weeks her time has improved (decreased) by 2%, and she can now run a quarter-mile in 66 seconds. What was her time six weeks ago?

Answers

Answer:

75 seconds

Step-by-step explanation:

Here, we want to get her time 6 weeks ago.

We shall have an exponential model to link this all up

The exponential model would look like;

y = I(1 - r)^n

where y is the present time

I is the initial time she started with which we are calculating

r is the rate of change which is 2% = 2/100 = 0.02

n is the week number which is 6 in this case

So we have;

66 = I(1 - 0.02)^6

66 = I(0.98)^6

I = 66/0.8858

I = 74.5 seconds

This is approximately 75 seconds

Her time 6 weeks ago is 75 seconds

Tim bought a video game console and games for $350. The video game console cost $200. Each game cost $25. How many games did Tim purchase?

Answers

Tim bought 6 games
Because 25x6=150 and he spent 200 on the console and he spent 350 total so your answer is $150

Answer:

Tim purchased 6 video games.

Step-by-step explanation:

Let's set the number of games Time purchased as x.

Due to each game costing $25, the total amount of money used on buying games would be ($25)x.

Hence, as the total amount of money used to buy both the console and the video games would be $350, the equation can be set as:

[tex]\$25x + \$200 = \$350[/tex]

[tex]\$25x = \$(350 - 200)[/tex]

[tex]x = \frac{\$150}{\$25}[/tex]

[tex]x = 6[/tex]

Therefore, Tim purchased 6 video games.

In the graph, when x=0, y=8. You can see on the x axis 0 is in the middle, and if you move up the y axis, you see the line intersects y=8.
