Use the information provided to write the equation of each parabola in vertex form and intercept form.

Answer:

Option F is true.

Step-by-step explanation:

The rule of reflection across the x-axis

P(x, y) → P'(x, -y)

For example, when a point P with coordinates (1, 2) is reflected across the x-axis, the coordinates of the image of point P will be: P'(1,-2).

i.e.

P(x, y) → P'(x, -y)

P(1, 2) → P'(1, -2)

Now, given FGH with vertices F(-1, 3), G(-5, 1), and H(-3, 5) reflected by Rx-axis.

Using the  rule of reflection across the x-axis

Thus, the coordinate of vertices F'G'H the image of FGH will be:

F(-1, 3) → F'(-1, -3)

G(-5, 1) → G'(-5, -1)

H(-3, 5) → H'(-3, -5)

Hence, option F is true.

Answer:

B) 3

Step-by-step explanation:

add 5 to both sides, 4x=12

divide both sides by 4, x=3

Answer:

The answer is B) 3

Step-by-step explanation:

You add 5 to 7 to move it from one side to the other

You should then have 4y=12

Then to solve for why you divide 12 by 4

You will get y=3

So your answer is 3

Answer:

i) The probability of getting 50 cent coin is 5/18, or approximately 28%

ii) To scale the numbers up to let us have 65 fifty cent coins, there would be a total of 234 coins

Step-by-step explanation:

We are told the probability of choosing ten and 20 cent coins, and from that we can work out the probability for the 50 cent coin.  All we need to do is add up the other two probabilities and subtract them from 1.

[tex]p = 1 - (\frac{1}{3} + \frac{7}{18})\\p = 1 - (\frac{6}{18} + \frac{7}{18})\\p = 1 - \frac{13}{18}\\p = \frac{5}{18}\\[/tex]

So the chance of getting a 50 cent coin is five eighteenths, or approximately 28%

For the second question We are asked to find the total number of coins if there are 65 fifty cent coins. (I can't see the text below that, but presumably it's saying that the ratios will stay the same).

We can solve this by comparing the two ratios, with x as the total, and solving for x:

[tex]\frac{5}{18} = \frac{65}{x}\\5x = 65 * 18\\x = 13 * 18\\x = 234[/tex]

So to keep the same ratios and have 65 fifty cent coins, we would need a total of 234 coins.

Answer:

The answer would be 80 black marbles.

Step-by-step explanation:

The student chose 10 marbles. 8 of those were black. There are 100 marbles total. Going at this rate, picking 10 at a time, 10x10 is 100. So we would do this 10 times. 8x10 is 80. 2x10 is 20. There are 80 black marbles.

Answer:

Yes it does

The constant of proportionality is 7.2

Step-by-step explanation:

Here, we are to determine if the expression represents a proportionality relationship

From the question, we can see that this is so

If we placed x beneath y, we will have

y/x = 7.2

So therefore the ratio between the two is 7.2 and thus, the equation represents a proportional relationship

Answer:

5 / 6

Step-by-step explanation:

Given that:

Probability that a dice rolled once will not land on 2

Probability = required outcome / Total possible outcomes

Total possible outcomes = (1, 2, 3, 4, 5, 6)

Required outcome = 2

P(not land on 2) = 1 - p(land on 2)

P(land on 2) = 1/6

P(not land on 2) = 1 - 1/6

P(not land on 2) = 5/6

Answer:

1. (3,19) and (-1,-13)

  to find the slope you need to do [tex]\frac{y2-y1}{x2-x1}[/tex]

Hence [tex]\frac{-13-19}{-1-3}[/tex]= 32/-4=-8

2. Take two points on the graph:

(-2,3) and (1,0)

Know that to calculate the slope you do

[tex]\frac{rise}{run}[/tex]= 4/2= 2

3. To find the slope in a table you need to choose any two points and utilize the following formula: [tex]\frac{y2-y1}{x2-x1}[/tex]= [tex]\frac{-16-(-8)}{2-1}[/tex]=-8/1= -8

4. Like in #1 we take the two points and plug it into the formula:

[tex]\frac{8-(-10)}{0-9}[/tex]=18/-9= -2

Answer:

I think he might need 100ml.

Step-by-step explanation:

Brandon needs to use 100 ml of water to make 250 ml of hand sanitizer.

The percentage is defined as a ratio expressed as a fraction of 100.

To save money, Brandon made his own hand sanitizer. Hand sanitizer needs 60% alcohol to be effective.

We have to determine the amount of water to manufacture 250ml of hand sanitizer.

To make 250ml of hand sanitizer with 60% alcohol, Brandon needs to use 250ml x 60% = 150ml of alcohol.

Since the total volume of the hand sanitizer is 250ml,

Brandon needs to use 250ml - 150ml = 100ml of water to make 250ml of hand sanitizer.

Therefore, he needs to use 100 ml of water to make 250 ml of hand sanitizer.

Answer:

Length of side AD is 6.5 units.

Step-by-step explanation:

Let the center of the rectangular base of the given pyramid is O,

From the picture attached,

m∠AOD = 90°

By applying Pythagoras theorem in the right triangle AOD,

AD² = AO² + OD²

AD² = 6² + (2.5)²

AD = √42.25

AD = 6.5 units

Therefore, length of side AD is 6.5 units.

Answer:

(x,y)=(-1,1)

Step-by-step explanation:

Given that,

3x + 5y = 2   .....(1)

6x - 10y = -16  ....(2)

Finding the value of x from equation (1).

[tex]x=\dfrac{2-5y}{3}[/tex]

Put the value of x in equation (2)

[tex]6(\dfrac{2-5y}{3}) - 10y = -16\\\\2(2-5y)-10y=-16\\\\4-10y-10y=-16\\\\-20y=-16-4\\\\y=1[/tex]

Put the value of y in equation (1) :

[tex]3x + 5(1) = 2\\\\3x=2-5\\\\3x=-3\\\\x=-1[/tex]

So, the solution of the equations is (-1,1).

1 necklace will therefore cost 34/4 = $8.5

Step-by-step explanation:

She spent between $39 and $59. let us find the average of the amount she spent = 39+59 / 2 = $49.

At an average, she spent $49.

The price of a bracelet is $5 and each bracelet costs the same amount and she bought 3 bracelets = $5 x 3 bracelets each = $15... She spent $15 on the bracelets.

Thus $49 - $15 = amount spent on the 4 necklaces = $34.

4 necklaces cost $34, 1 necklace will therefore cost 34/4 = $8.5

Answer:

A = 7t + 100 and C = 10t+55 are the equations for each situation and they both will have an amount of $205 after 15 weeks.

Step-by-step explanation:

Given that:

Alyssa started savings with $100

Saved amount each week = $7

A = Amount of money Alyssa have

t = number of weeks

A = 7t + 100

Colton started savings with $55

Saved amount each week = $10

C = 10t + 55

For same amount;

A = C

7t+100 = 10t+55

100-55=10t-7t

45=3t

3t=45

Dividing both sides by 3

[tex]\frac{3t}{3}=\frac{45}{3}\\t=15[/tex]

Putting t=15 in Alyssa's equation

A = 7(15)+100

A = 105+100 = $205

Hence,

A = 7t + 100 and C = 10t+55 are the equations for each situation and they both will have an amount of $205 after 15 weeks.

Answer:

Total monthly expenditure = Rs 115,500

Total savings = Rs 49,500

Step-by-step explanation:

Total salary = Rs 165000.

Food = 20%

= 20/100 × Rs 165,000

= 0.2 × 165,000

= Rs 33,000

House rent = 25%

= 25/100 × Rs 165,000

= 0.25 × 165,000

= Rs 41,250

Fuel = 10%

= 10/100 × Rs 165,000

= 0.1 × 165,000

= Rs 16,500

Miscellaneous = 15%

= 15/100 × Rs 165,000

= 0.15 × 165,000

= Rs 24,750

Total monthly expenditure = food + house rent + fuel + miscellaneous

= Rs 33,000 + Rs 41,250 + Rs 16,500 + Rs 24,750

= Rs 115,500

Total monthly expenditure = Rs 115,500

Total savings = Total salary - Total expenditure

= Rs 165,000 - Rs 115,500

= Rs 49,500

Total savings = Rs 49,500
