Answer:

20. A. y= 10x = 15

21. C. Php 75.00

22. B. Php 195.00

Step-by-step explanation:

She has to pay 25 Pesos for one hour and only ten more each hour after that. That can be represented in the formula Y= 10x +15. To solve the rest of the questions, just substitute 6 hours for question 21 and 18 hours for question 22.

Answers

A, y= 10x + 15

C, 75.00

B, 195.00

Explanation for the first question:

We can see in the table the price is going up by 10

25 to 35 to 45, etc

So 10x + 15

Explanation for question 2:

We know the equation is 10x + 15. X is the amount of hours so that is our 6. If you plug it into the equation you get

10(6) + 15

Multiply first

60+15

Then add

You get 75.

Explanation for question 3:

Do the same as question 2 just with 18 instead of 6.

10(18) + 15

Multiply

180 + 15

Add

195

Given: 2PQ = PR

Statement: 2PQ = PQ + QR
Reason: ???

Answers

Answer:

Given: 2PQ = PR

Prove: Q is the midpoint of line PR

Statement: 2PQ = PQ + QR

Step-by-step explanation:

If Q is the midpoint of PR then

PR = PQ + QR [by segment addition postulate]

2PQ = PR [given]

2PQ = PQ + QR

2PQ-PQ = PQ + QR-PQ [by subtracting PQ from both sides]

PQ = QR

[tex] \because[/tex] Q lies on PR and PQ = QR

[tex] \therefore[/tex] Q is the midpoint of PR

Step-by-step explanation:

There are 4 A's and 3 B's, so the ratio would be 4:3.

The ratio would not be 3:4, because you are asking for A's to B's, and not B's to A's.

Answer:

4:3

Step-by-step explanation:

There are 4 A's in this set and only 3 B's. Often confused as 3:4, however, that would be the ratio of B's to A's. This ration can't be simplified either leaving it at 4:3.

Write an equation of the parabola in intercept form (3, 4) (4,0) (2,0)
An equation of the parabola is y=?​

Answers

The equation of the parabola is gotten as;

 y = -4x² + 24x - 32

We are given the coordinates of a parabola to be;

(3, 4) ; (4,0) ; (2,0)

The general form of equation of a parabola is given by;

y = ax² + bx + c

Let's plug in the x and y coordinates as given to us from the question.

For coordinate (3, 4), the equation is;

(3²)a + 3b + c = 4

9a + 3b + c = 4  ----(eq 1)

For coordinate (4, 0), the equation is;

(4²)a + 4b + c = 0

16a + 4b + c = 0  ----(eq 2)

For coordinate (2, 0), the equation is;

(2²)a + 2b + c = 0

4a + 2b + c = 0  ----(eq 3)

Solving the 3 equations using an online simultaneous equation solver tool, we have; a = -4; b = 24; c = -32

Plugging these values of a, b and c into the general equation of parabola gives us;

       y = -4x² + 24x - 32

Evaluate the function at x = -3.

Answers

Answer:

hold on

Step-by-step explanation:

Given the function, p(x) = 4x^3 + 2x^2 - 3x + 2:

We can substitute the value of x = -3 as input into the given function:

p(-3) = 4x^3 + 2x^2 - 3x + 2

p(-3) = 4(-3)^3 + 2(-3)^2 - 3(-3) + 2

p(-3) = 4(-27) + 2(9) - 3(-3) + 2

p(-3) = -108+ 18 - (-9) + 2

p(-3) = -90 + 9 + 2

p(-3) = -81 + 2

p(-3) = -79

Destiny and Franijza are at the swimming pool. They decide to walk to the ice cream shop. They walk north at a pace of 6 km/h * r for 20 minutes, and then east at the same pace for 10 minutes. If the swimming pool is at the origin (0, 0) what is the position of the ice cream shop?

Answers

Answer:

(1,2)

Step-by-step explanation:

6 km/h going north for 20 mins would be 1/3 of an hour so 1/3 of 6. This would mean they walked 2 kilometers north. That's your y-coordinate. They walked 6 kilometers an hour going east for 10 mins. 10 mins is 1/6 of an hour and 1 is 1/6 of 6. So 1 is your x-coordinate. You put the numbers in as (x, y).

If the swimming pool is at the origin (0, 0) then the position of the ice cream shop is (1,2) and this can be determined by using the unitary method and also by using the formula of speed.

Given :

Destiny and Franijza are at the swimming pool. They decide to walk to the ice cream shop. They walk north at a pace of 6 km/h for 20 minutes, and then east at the same pace for 10 minutes.

The following steps can be used in order to determine the position of the ice cream shop:

Step 1 - Remember 1 hour is equal to 60 minutes.

Step 2 - If one hour is equal to 60 minutes then in 20 minutes there are:

[tex]\rm \dfrac{20}{60}=\dfrac{1}{3}\;hour[/tex]

Step 3 - If one hour is equal to 60 minutes then in 10 minutes there are:

[tex]\rm \dfrac{10}{60}=\dfrac{1}{6}\;hour[/tex]

Step 4 - Determine the distance travel in the north which gives the y-coordinate.

[tex]\rm Distance = 6\times \dfrac{1}{3}=2\;Km[/tex]

Step 5 - Determine the distance travel in the east which gives the x-coordinate.

[tex]\rm Distance = 6\times \dfrac{1}{6}=1\;Km[/tex]

So, the position of the ice cream shop is (1,2).
