Answer:

2/3

Step-by-step explanation:

Answer:

a=2/3

Step-by-step explanation:

1. y=a(x-x1)(x-x2) is a formula for a parabola, x1 and x2 being points where y=0 so in the equation y=a(x-3)(x+2), you know

x1=3, x2=-2

2. Find distance between 3 and -2, which is 5

3. bh/2=A --> 5h/2=10 --> h=4  (h is height)

4. when x=0, y=-6a, y=a(0-3)(0+2)

5. because parabola opens upward, the point of the vertex must be (_, -4)

6. -6a= -4

     a=2/3

Answer:

5 pizzas

Step-by-step explanation: If you have 10 people and each will get two slices then you will need 20 pieces of pizza because 10x2 is 20. If each pizza has 4 slices then you will need 5 pizzas because 4/20 is 5.

Answer:

5 pizzas.

Step-by-step explanation:

Find out how many slices the group of 10 people need in total:

2 x 10 = 20 slices

Now, use the total number of slices and divide it with 4 to find how many pizzas they need.

20 ÷ 4 = 5

They need 5 pizzas for 10 people who each get 2 slices.

Answer: d, a, and c

Step-by-step explanation:

Part(A)

The ordered pair (2.5, 20) represents $2.50 for 20 hours. the correct option is A.

Part(B),

Yes. the line passes through the origin. The correct option is A.

Part(C),

The linear equation represented by the graph is y = 8x. The correct option is C.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that coordinates are (0.5, 4), (1, 8), (1.5, 12), (2, 16), and (2.5, 20).

Part(A),

The ordered pair (2.5,20) represents that the earning is $20 for the work of 2.5 hours.

Part(B),

The slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 8 - 4 ) / ( 1 - 0.5 )

Slope = 4 / 0.5

Slope = 40 / 5

Slope = 8 hours

The y-intercept is calculated as,

y = mx + c

16 = ( 2 x 8 ) + c

c = 16 - 16

c = 0

Hence, the line passes through the origin.

Part(C),

The equation of the line will be written as,

y = mx + c

y = 8x + 0
y = 8x

Answer:

22% are undecided

36% plan to vote Republican

42% plan to vote Democratic

Step-by-step explanation:

Take 318 and divide it by 750 to find the democratic vote. Round to the nearest whole number.

318/750 = 0.424

Same for Republican except take 268 and divide by 750.

268/750 = 0.357

Add both percentages together. 36% + 42% = 78%

So there is 22% of the population that either did not answer or are undecided.

The correct answers are:

22% are undecided

36% plan to vote Republican

42% plan to vote Democratic

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Total Resident = 750

Out of which 318 planned to vote for the Democratic candidate, 268 planned to vote for the Republican candidate.

So, 318/750 = 0.424

                    = 42.4%

and, 268/750 = 0.357

                       = 35.7%

So, the percentage who decided to vote = 36% + 42% = 78%

Hence, there is 22% of the population that either did not answer or are undecided.

Answer:

Parker is NOT right when he says that it is a division problem 6 ÷ 3.

In fact, it is a multiplication problem 6 × 3 because 6 × 3 = 18 would give us the correct number of total rectangles which are 18

Step-by-step explanation:

Total number of rectangles = 18

As there are 3 rows with each row containing 6 rectangles.

Now, if we multiply 6 with 3, we get the result 18.

Thus,

6 × 3 = 18

Hence, Parker must have mentioned that this arrow of 18 rectangles shows the multiplication problem 6 × 3.

Thus,

Parker is NOT right when he says that it is a division problem 6 ÷ 3.

In fact, it is a multiplication problem 6 × 3 as 6 × 3 = 18 would give us the correct number of total rectangles which are 18.

Answer:

  D.  John's boat was farther and faster

Step-by-step explanation:

The equation tells you that at x = 0, Roberta's boat was 10 miles from the dock. The words tell you John's boat started 20 miles from the dock, so his boat started farther away.

John's boat traveled a distance of (55 -20) = 35 miles in 5 hours, so the speed was (35 mi)/(5 h) = 7 mi/h. The equation tells you Roberta's boat traveled 6 miles for each hour, so John's boat was faster.

  John's boat was farther and traveled more quickly

__

Additional comment

The variables in Roberta's equation are not defined. In order for the problem to make sense, we must assume that x represents time in hours, and y represents distance in miles.

Answer:

y = 5(3)+3

= 15 +3

Maria calculate that she could make 18,000 over the summer instead she ended up making 15,000 what is the percentage difference? round your answer to the nearest percent

The formula for Percent difference =

Difference/ Original value × 100

Difference is calculated as:

18000 - 15000 = 3000

Original value = 15000

Hence:

3000/15000 × 100

= 20%

Percent difference = 20%

The length of side k is approximately 6.56 inches.

A planar triangle's side's square is equal to the sum of the squares of the other sides minus the product of those sides and the cosine of the angle between them, divided by two.

We can use the Law of Cosines to find the length of side k:

k² = l² + m² - 2lm cos(K)

where K is the angle opposite side k.

In this case, we have l = 2.4 inches, m = 4.2 inches, and K = 159°. Substituting these values into the formula, we get:

k² = (2.4)² + (4.2)² - 2(2.4)(4.2)cos(159°)

Using a calculator to evaluate the cosine, we get:

k² = 5.76 + 17.64 - 19.96(-0.987688)

k² ≈ 43.11

Taking the square root of both sides (and rounding to the nearest tenth), we get:

k ≈ 6.56 inches

Therefore, the length of side k is approximately 6.56 inches.
