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.

Answer:

A) cotx = cosx/sinx    

C) tanx = 1/cotx

Step-by-step explanation:

A)

cosx/sinx = 1/(sinx/cosx) = 1/tanx = cotx

Therefore, cotx = cosx/sinx  

C)

Similarly;

1/tanx = cotx

Therefore,

1 = tanxcotx

1/cotx = tanx

and

tanx = 1/cotx

B) cscx=1/cosx is not true since;

1/cosx = secx

and

cscx = 1/sinx

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 )

x = [tex]\frac{-12}{-8}[/tex] = [tex]\frac{3}{2}[/tex] = 1.5

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,

Final answer:

The scale factor from Solid A to Solid B is found by taking the cube root of the ratio of their volumes, resulting in approximately 0.6996.

Explanation:

The question involves finding the scale factor between two similar solids based on their volumes. Since the volumes of similar solids are related by the cube of the scale factor, we can find the scale factor by taking the cube root of the ratio of their volumes. Solid A has a volume of 171.5 m³, and Solid B has a volume of 500 m³. To find the scale factor from Solid A to Solid B, we calculate the cube root of (171.5/500), which will give us the linear scale factor.

The formula we use is:

Scale Factor (k) = ∛(Volume of Solid A / Volume of Solid B)

k = ∛(171.5 m³ / 500 m³)

k ≈ ∛(0.343) ≈ 0.6996

Therefore, the scale factor of Solid A to Solid B is approximately 0.6996.

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.

To find the probability of a randomly chosen person playing baseball in a country, you need to use the given probabilities and conditional probability formula.

To find the probability that a randomly chosen person from this country plays baseball, denoted as B:

The probability that a randomly chosen person from the country plays baseball is 0.068.

To find the probability that a randomly chosen person from a particular country plays baseball, we will use the given information and apply Bayes' theorem.

We are given:

We are asked to find the probability that a randomly chosen person is a baseball player (P(B)).

Using Bayes' theorem, we can express P(B) as P(L and B) / P(L | B). Plugging in the known values:

P(B) = P(L and B) / P(L | B) = 0.017 / 0.250 = 0.068

Therefore, the probability that a randomly chosen person plays baseball is 0.068, precise to three decimal places.

Perimeter is the outside dimensions.

There are two sides 5z and two sides 4z +3.

5z +5z +4z+3 + 4z +3 = 186

Combine like terms:

18z + 6 = 186

Subtract 6 from both sides:

18z = 180

Divide both sides by 18:

z = 180 / 18

z = 10

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:

4153

Step-by-step explanation:

Let the original number be  [tex]\overline{abc3}[/tex]  [a is the number of thousands, b - the number of hundreds, c - the number of tens, 3 - the number of ones]

If you put the number 3 in the first position, the number will be [tex]\overline{3abc}[/tex]

New number is 738 less than old number.

When you subtract from 3 some number c and get 8, then you have to lend one ten and subtract this number c from 13. So, 13-5=8. Thus, c=5. Remember about lending! Now when you subtrat from 4 (not 5 because of lending) some number b and get 3, then b=1. Now when you subtract from 1 some number a and get 7, then you have to lend 1 from the number of thousands and subtract a from 11 to get 7, thus 11-4=7 and a=4.

We're asked for [tex] a_{90}[/tex]

[tex]a_{90} = 3(90) - 2 = 268[/tex]

Answer: C 268

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.

Answer:

D

Step-by-step explanation:

If you drew a line of best fit to encompass all the data points it would be a line that has a negative slope. The correlation coefficient would be negative.

The option (D) the data shows a negative linear relationship because the slope of the line is negative.

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]

As we can see in the picture, the dots pattern are going up to down if we draw a line of best fit.

The slope of the line will be negative.

We can say the relationship between car's value and car's age is negative correlated.

Thus, the option (D) the data shows a negative linear relationship because the slope of the line is negative.
