Answer:

(x + 9)(x - 7)

Step-by-step explanation:

We want to factorize [tex]x^2 + 2x - 63[/tex]

We need to find two numbers such that their product is -63 and they add up to +2. The two numbers are +9 and -7:

[tex]x^2 + 9x - 7x - 63\\\\= x(x + 9) -7(x +9)\\\\ = (x +9)(x -7)[/tex]

The complete factorization is (x + 9)(x - 7)

The factored form of the expression x² + 2x - 63 is (x + 9)(x - 7).

What is the factored form of the expression?

Given the expression in the question:

x² + 2x - 63

To determine the complete factorization of the quadratic expression x² + 2x - 63, we aim to break it down into its simplest factors.

This is achieved through factoring, a process of identifying the expressions that, when multiplied, result in the original quadratic expression.

x² + 2x - 63

Now, find a pair of integers whose sum equals 2,

and whose product equals -63.

We use integers 9 and -7.

Next, rewrite the quadratic expression using these factors:

(x + 9)(x - 7)

Therefore, the complete factorization of x² + 2x - 63 is (x + 9)(x - 7).

Option C) (x + 9)(x - 7) is the correct answer.

The slope is 3/2

Step-by-step explanation:

To find slope you do rise over run

Rise being how much you go up or go down

Run being how much you move sideways

Always measure Rise first, it is the numerator and then Run as the denominator.

Answer:

m= 3/2.

Step-by-step explanation:

To find the slope, use the two points shown in the graph which as (-1, 2) and (1, 5). Plug these into the slope formula [tex](m= \frac{y_{2}-y_{1} }{x_{2}-x_{1}} )[/tex]

[tex]m= \frac{5-2 }{{1+1}}[/tex]

[tex]m= \frac{3}{2}[/tex]

Therefore, the slope of the graph is 3/2.

sin 118 sin 29

------------ = ----------

n 15

Using cross products

15 sin 118 = n sin 29

Divide by sin 29

15 sin 118 / sin 29 = n

27.31838095 = n

sin 33 sin 29

------------ = ----------

p 15

Using cross products

15 sin 33 = p sin 29

Divide by sin 29

15 sin 33 / sin 29 = p

16.8511209 = p

Answer:

The number of sweatshirts for which cost and income are equal

Step-by-step explanation:

Let y₁ represent the revenue from selling "x" sweatshirts and y₂ represent the cost of producing "x" sweatshirts, solving the system:

[tex]y_1=35x\\y_2=-0.05(x-400)^2+9,492\\y_1=y_2\\35x=-0.05(x-400)^2+9,492\\-0.05(x-400)^2-35x+9,492=0[/tex]

The solution of the equation above yields the number of sweatshirts for which the cost of production (y₂ ) is equal to the revenue from sales (y₁).

Therefore, the solution represents the number of sweatshirts for which cost and income are equal.

The number of sweatshirts for which cost and income are equal and this can be determined by using the substitution method.

Given :

In the first equation in the system of equations, y represents the money collected from selling sweatshirts. In the second equation, y represents the money spent to produce x sweatshirts with team logos on them for a professional sports league.

The following steps can be used in order to determine the solution of the system of the equation:

Step 1 - Write the given system of equations.

[tex]y = 35x[/tex] ---- (1)

[tex]y = -0.05(x - 400)^2+9492[/tex] ---- (2)

Step 2 - Now, substitute the value of 'y' in equation (2).

[tex]35x = -0.05(x - 400)^2+9492[/tex]

Step 3 - Simplify the above equation.

[tex]35x = -0.05x^2-8000+40x+9492[/tex]

Step 4 - Now, write the above equation in generalized quadratic form.

[tex]0.05x^2-5x-1492=0[/tex]

From the above steps, it can be concluded that the correct statement is given by option D).

at the secretary job she made 12.75 an hour

second job she made 13.50 an hour

180 minutes is 3 hours divide 40.50 by 3 and get 13.50

102.00 divided by 8 is 12.75

Step-by-step explanation:

8 hours = 102.00

1 hour = 102 ÷ 8 = 12.75

180 min = 3hr

3hr = 40.50

1hr = 40.50 ÷ 3 = 13.5

Answer:

90,747

Step-by-step explanation:

Clair delivery=79 per day

Total delivery per year=79×365 days

=28,835

Reagan delivery=2490 per month

Total delivery per year=2490×12 months

=29,880

Anthony delivery= 616 per week

Total delivery per year =616×52 weeks

=32,032

Total delivery altogether in a year=28,835+29,880+32,032

=90,747

Answer:

Step-by-step explanation:

Clair delivers 79 papers a day.

Assuming that there are 365 days in a year, it means that the number of newspapers that Clair delivers in a year is

79 × 365 = 28835

Reagan delivers 2490 papers a month. There are 12 months in a year. it means that the number of newspapers that Reagan delivers in a year is

12 × 2490 =29880

Anthony delivers 616 papers a week. Assuming that there are 52 weeks in a year, it means that the number of newspapers that Anthony delivers in a year is

52 × 616 = 32032

Therefore, the number of newspapers that they deliver altogether in a year is

28835 + 29880 + 32032 = 90747

Answer:

55% of the people surveyed were satisfied with the​ car

Step-by-step explanation:

The proportion of people surveyed who were satisfied with the car is the number of people who said they would buy that type of car again divided by the total number of people survied.

The percentage is the proportion multiplied by 100.

We have that:

2,300 people surveyed

1,265 said they would buy that type of car again.

1265/2300 = 0.55

0.55*100 = 55%

55% of the people surveyed were satisfied with the​ car

Answer:

Step-by-step explanation:

Using the Empirical Rule, it is found that 99.7% of his commutes will be between 36 and 54 minutes.

What does the Empirical Rule state?

It states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, considering a mean of 45 minutes and a standard deviation of 3 minutes, we have that:

36 = 45- 3 x 3

54 = 45 + 3 x 3

Within 3 standard deviations of the mean, hence, 99.7% of his commutes will be between 36 and 54 minutes.
