Answer: (2x + 5)(2x - 5)

Answer:

(2x - 5) and (2x + 5)

Step-by-step explanation:

There's a special formula for factoring the difference of two squares:

a^2 - b^2 = (a - b)(a + b).

Thus,

4x^2 - 25 is the same as (2x)^2 - (5)^2, and the two factors are:

(2x - 5) and (2x + 5).

Answer:

The correct option is D.

Step-by-step explanation:

It is given that the table represents the total price including parking, p(t), for family fair packages with various numbers of included tickets, t.

t     :  0    10      20     30     40     50

P(t) : 15   27.5   40    52.5   65   77.7

Choose any points from the table. (0,15) and (10,27.5).

The equation of function is

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-15=\frac{27.5-15}{10-0}(x-0)[/tex]

[tex]y-15=\frac{12.5}{10}(x)[/tex]

[tex]y-15=1.25x[/tex]

Add 15 on both the sides.

[tex]y=1.25x+15[/tex]

[tex]P(t)=1.25t+15[/tex]

The family has a budget of $90.

[tex]P(t)\leq 90[/tex]

[tex]1.25t+15\leq 90[/tex]

Subtract 15 from both the sides.

[tex]1.25t\leq 75[/tex]

Divide both sides by 1.25.

[tex]t\leq 60[/tex]

Domain is the set of inputs or the values of t.

[tex]Domain=\{t|0\leq t\leq 60,t\in W\}[/tex]

Range is the set of outputs or the values of function p(t).

[tex]Range=\{P(t)|15\leq P(t)\leq 90,P(t)\in R\}[/tex]

Therefore the correct option is D.

Final answer:

The correct restricted domain is all whole numbers from 0 to 50 inclusive, and the restricted range is all real numbers from 15 to 77.5 inclusive, given the family's budget constraint of $90. Therefore, the correct option is B.

Explanation:

The problem presented involves determining the restricted domain and range of a function p(t) that reflects the total price, including parking, for family fair packages with a varying number of included tickets (t). Considering the family's budget of $90, we must identify the correct domain and range within this context. The domain here is the number of tickets, which can only take on certain specified values, and the range is the pricing associated with those ticket amounts. The possible ticket numbers (t) are 0, 10, 20, 30, 40, 50, and the corresponding prices (p(t)) are 15, 27.5, 40, 52.5, 65, 77.5.

Considering the given budget constraint, the domain and range must also not exceed $90. Thus, we exclude any ticket numbers or prices above this threshold when determining the domain and range. The correct answer to the question is B: The domain is restricted to all whole numbers from 0 to 50 inclusive. The range is all real numbers from 15 to 77.5 inclusive since these are the observed outputs from the function p(t) within the family's budget.

Hello There!

The answer to adding 3/14 and 1/7 together give you a sum of 5/14

STEP #1 The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

STEP #2 Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

The sum of the measure of the angles in a triangle are 180 degrees.

In this formula solve for x

32 + 70 + x = 180

102 + x = 180

(102 - 102) + x = 180 - 102

x = 78

The last angle is 78 degrees

Answer:

x = 39.1

Step-by-step explanation:

Points to remember

Mean of a data set is given by

Mean = (sum of data set)/Total number of data

To find the value of x

It is given a data set

31.7, 42.8, 26.4, x

Mean = 35

Sum of data set = 31.7 + 42.8 + 26.4 + x = 100.9 + x

(100.9 + x)/4 = 35

100.9 + x = 35 * 4 = 140

x = 140 - 100.9 = 39.1

Therefore x = 39.1

Answer:

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

Step-by-step explanation:

To eliminate the fraction multiply all terms on both sides by 3

(x - 3) - 3x + 9 = 6(x - 1) ← distribute parenthesis on both sides

x - 3 - 3x + 9 = 6x - 6

- 2x + 6 = 6x - 6 ( subtract 6x from both sides )

- 8x + 6 = - 6 ( subtract 6 from both sides )

- 8x = - 12 ( divide both sides by - 8 )

ANSWER

B. (-1,0)

EXPLANATION

The x-intercepts are the points where the graph touches the x-axis.

We can observe from the graph that, the graph touches the x-axis at:

x=-2, x=-1, x=1 and x=2.

Therefore the x-intercepts are (-2,0),(-1,0),(1,0) and (2,0).

From the given options, the only point which is an x-intercept is (-1,0)

The second choice is correct.

The x-intercepts of the graph given in the question is (-1,0). Therefore, the second option is correct.

The x-intercepts are the points on the graph where it intersects the x-axis.

In the graph provided in the question, it is observed that the graph touches the x-axis at x = -2, x = -1, x = 1, and x =2.

Therefore, the intercepts of the x-axis are (-2,0),(-1,0),(1,0), and (2,0). So, from the given options (-1,0) is satisfied,

The second option is correct.

Answer:

y = (-3/2)x - 4

Step-by-step explanation:

If y = (2/3)x + 9, the slope is 2/3.  Any line perpendicular to this line would have the slope -3/2, which is the negative reciprocal of 2/3.

If the perpendicular line passes thru (-6, 5), then the equation in slope-intercept form would be:

y = mx + b, or (here) 5 = (-3/2)(-6) + b.  From this we see that b = -4, and the desired equation is y = (-3/2)x - 4 (Answer Choice #3)

Answer:

20

Step-by-step explanation:

5! = 5*4*3*2*1

3! = 3*2*1

5!/3! = 5*4*3*2*1

           ----------------

           3*2*1

Canceling common factors

      = 5*4

       = 20

For this case we have that by definition, the factorial of a number is the product of the "n" consvutive factors from n to 1. The factors are in descending order, that is:

[tex]n! = n (n-1) (n-2) ... 3 * 2 * 1[/tex]

Then, we have the following expression:

[tex]\frac {5!} {3!}[/tex]

Applying the definition we have:

[tex]\frac {5!} {3!} = \frac {5 * 4 * 3 * 2 * 1} {3 * 2 * 1} = \frac {120} {6} = 20[/tex]

Answer:

1. 48 square feet

2. 308 square feet

Step-by-step explanation:

1.

The entry terrace is shaped as a trapezoid and the area of a trapezoid is given as:

Area of Trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

Where

b_1 and b_2 are the 2 parallel bases

and h is the perpendicular height

From the diagram, we see that the 2 bases are 16 and 8 and height is 4.

Plugging into the formula, we get:

Area of Entry Terrace = [tex]\frac{1}{2}(b_1+b_2)h=\frac{1}{2}(16+8)*4=\frac{1}{2}(24)(4)=48[/tex]

2.

The total area comprises of the area of entry terrace + playroom + back porch.

The area of the back porch is 6 * 6 = 36 (it is shaped like a square and square has area of side * side)

The area of the playroom is 14 * 16 = 224 (it is a rectangle and rectangle has area of base * height)

Total area of treehouse = 48 + 36 + 224 = 308 square feet

Answer:

Answer:

-0.125

Step-by-step explanation:

The points on the graph referenced by the problem statement are ...

(x, y) = (-1, -0.25)

(x, y) = (1, -0.50)

The average rate of change between the two points is ...

(∆y)/(∆x) = (-0.50 -(-0.25))/(1 -(-1)) = -0.25/2 = -0.125

The average rate of change of the function shown on the interval [-1, 1] is -0.125.

Answer:

-0.125

Step-by-step explanation:

Davis spent a total of $755 on buying and refurbishing the cycle, which he sold for $900. He made a gain of $145 on the sale.

To calculate Davis's gain or loss from buying and selling the second-hand cycle, we need to determine the total cost he incurred and compare that to the sale price. First, we add the purchase price of the cycle to the cost of repairs and repainting:

The total cost Davis incurred is $500 + $80 + $175, which equals $755.

Next, we must compare this to the sale price, which is $900. To find the gain, we subtract the total cost from the sale price:

$900 - $755 = $145

Therefore, Davis made a gain of $145 from this transaction.

Davis gained $145 by selling the cycle for $900 after incurring a total expense of $755 on its purchase, repairs, and repainting.

To calculate whether Davis made a gain or a loss from buying and selling the cycle, we need to consider the total cost of the cycle (including repairs and repainting) and the selling price. First, we add up the initial cost of the cycle ($500), the cost of repairs ($80), and the cost of repainting ($175). This will give us the total cost. Then, we subtract this total cost from the selling price ($900).

Total cost = Cost of cycle + Repairs + Repainting = $500 + $80 + $175 = $755

Profit or Loss = Selling price - Total cost = $900 - $755

Profit or Loss = $900 - $755 = $145

Davis gained $145 from this transaction because the selling price was higher than the total cost.
