Final answer:

To find tan A in a right-angled triangle where the sides are given, first use Pythagoras' theorem to find the missing side, then apply the definition of tangent as the ratio of the opposite to the adjacent side, resulting in tan A = 1.875.

Explanation:

In triangle ABC, where angle C is a right angle, and we are given that c = 17 (hypotenuse) and a = 8 (adjacent to angle A), the task is to find tan A. Since we are dealing with a right-angled triangle, we can use Pythagoras' theorem to find the length of side b (opposite to angle A). The theorem states a² + b² = c². Given a = 8 and c = 17, we can find b:

b² = 17² - 8² = 289 - 64 = 225, thus b = 15.

The tangent of an angle in a right-angled triangle is given by the opposite side divided by the adjacent side. Therefore, tan A = b/a = 15/8. Hence, tan A for this triangle equals 1.875.

The another way to state the transformation would be [tex](x,y)>(-x,-y)[/tex]

Solution:

Rotation about the origin at [tex]180^\circ[/tex]: [tex]R_{180^\circ}A \rightarrow O = R_{180^\circ} (x, y) \rightarrow (-x,-y)[/tex]

The term R0 means that the rotation is about the origin point. Therefore, (R0,180) means that we are rotating the figure to [tex]180^\circ[/tex] about the origin.

So, the transformation of the general point (x,y) would be (-x,-y) when it is rotated about the origin by an angle of [tex]180^\circ[/tex].

Hence according to the representation, the expression would be [tex](x, y) \rightarrow (-x, -y)[/tex].

The transformation R0, 180° is equivalent to reflecting each point (x, y) in a Pentagon across the origin, resulting in the new coordinates (-x, -y).

The transformation rule R0, 180° involves rotating a point (x, y) within a Pentagon by 180 degrees around the origin. In this transformation, each point is mirrored or reflected across the origin. To express this transformation differently, we can say that (x, y) is mapped to its mirror image in both the x-axis and y-axis. In other words, the x-coordinate is reversed (negated), and the y-coordinate is also reversed (negated).

So, the alternative way to state this transformation is: (x, y) > (-x, -y). This means that any point (x, y) in the original Pentagon will become (-x, -y) after the transformation.

For example, if we have a point (2, 3) within the Pentagon, applying the transformation yields (-2, -3). This means the point's x-coordinate is changed from 2 to -2, and the y-coordinate is changed from 3 to -3. This transformation is essentially a 180° rotation or a reflection through the origin.

Answer:

$6,632.55

Step-by-step explanation:

What a coincidence I was doing the same question. Ok so you should know about the Compound Interest formula which is A=P (1+r/100) n. (n) is btw in the exponent.

A= ?

P=6250

r=2

n=3

   Anyways we will input everything we are given so it will be:

A=6250(1+2/100)3

   Since A is final amount - it will be our answer which is  $6,632.55

Final answer:

Carol invested $6,250 at a rate of 2% per year compound interest. After 3 years using the compound interest formula A = P(1 + r/n)^(nt), her investment will grow to $6,632.55.

Explanation:

Carol invested $6,250 at a rate of 2% per year compound interest. To calculate the total amount Carol has after 3 years, we can use the formula:

A = P(1 + r/n)^(nt)

Where:

Since the interest is compounded yearly, n will be 1. Assuming the 2% interest rate is already in decimal form (0.02), and the time is 3 years, we substitute these values into the formula:

A = 6250(1 + 0.02/1)^(1*3)

A = 6250(1 + 0.02)^3

A = 6250(1.02)^3

A = 6250 * 1.061208

A = $6632.55

Therefore, after 3 years, Carol's investment will have grown to $6632.55.

Answer: 1.3

Step-by-step explanation:

Step 1: convert to decimal

56% = 56/100 = 0.56

43% = 43/100 = 0.43

Step 2; divide the values

0.56/0.43= 1.3

Step-by-step explanation: google help

The area is a function of the radius and the radius is a function of the area.

For a circle of radius R, we can write the area as:

A = pi*R^2

So we can write the area in terms of the radius, meaning that yes, the area is a function of the radius of a circle.

If we take the above equation and we isolate R, we get:

R = √(A/pi)

The value of [tex](f+g)(x)[/tex] is [tex]5 x^{2}-4[/tex]

Explanation:

Given that the functions [tex]f(x)=4 x^{2}+1[/tex] and [tex]g(x)=x^{2}-5[/tex]

We need to determine the value of [tex](f+g)(x)[/tex]

The value of [tex](f+g)(x)[/tex] can be determined by substituting the value of [tex]f(x)[/tex] and [tex]g(x)[/tex] and simplifying the terms.

Thus, let us assign [tex]f(x)=4 x^{2}+1[/tex] in the function [tex](f+g)(x)[/tex], we have,

[tex]4 x^{2}+1+g(x)[/tex]

Now, let us assign [tex]g(x)=x^{2}-5[/tex] in the function [tex](f+g)(x)[/tex], we get,

[tex]4 x^{2}+1+x^{2}-5[/tex]

Grouping the like terms, we have,

[tex]4 x^{2}+x^{2}+1-5[/tex]

Adding the like terms, we get,

[tex]5 x^{2}-4[/tex]

Hence, the value of [tex](f+g)(x)[/tex] is [tex]5 x^{2}-4[/tex]

Answer:

1 + 2

Step-by-step explanation:

When we look at the number line, we can see that the inequality is:

x ≤ 19

This means that all values of "x", must be equal to or less than 19.

To find the correct answer choices, we must keep that equation in mind.

1. at most 19 cups   -   this answer choice does work, because it shows that 19 is the limit (which is what our inequality represents)

2. 19 cups or less    -     this answer choice works as well because it shows that 19 is the maximum and all other values of "x" must be below that.

3. more than 19 cups   -  this goes against our inequality, since "x" can't exceed 19. This means that this answer choice must be incorrect.

4. a minimum of 19 cups   -   this answer choice also cannot be correct since it shows that "x" can go over 19 (which we know is false).

5. no fewer than 19 cups   -    this is also wrong because it wants "x" to go over the value of 19, which it can't do.

Final answer:

Stephanie's annual income is $49,348, while Tahlia's is $45,852, making Stephanie's weekly earnings $67.61 higher than Tahlia's. Stephanie earns $949.38 per week, and Tahlia earns $881.77 per week.

Explanation:

To calculate each person's equivalent annual income, we must standardize their earnings to a common time frame. We consider a year to have 26 fortnights and 12 months.

Stephanie's Annual Income

Stephanie is paid every fortnight, so we multiply her fortnightly income by the number of fortnights in a year:

$1898 per fortnight x 26 fortnights per year = $49,348 per year.

Tahlia's Annual Income

Tahlia is paid monthly, so we multiply her monthly income by the number of months in a year:

$3821 per month x 12 months per year = $45,852 per year.

To determine who earns more per week, we divide the annual income by the number of weeks in a year (52). Stephanie earns $949.38 per week ($49,348 / 52), while Tahlia earns $881.77 per week ($45,852 / 52). Stephanie earns more per week by:

$949.38 - $881.77 = $67.61.

Therefore, Stephanie earns $67.61 more than Tahlia per week.

f(4) is 49

Explanation:

Given:

f(4) = ?

we have to substitute the value of x = 4 in the given equation.

f(4) = 12 X 4 + 1

f(4) = 49

Whenever there is such type of question then we have to just put the value of x in the equation. In case of f '(4) then we have to differentiate the given equation with respect to x first and then substitute the value of x in the differentiated equation.

Therefore, f(4) is 49

1277/16=79.8 = 80 (Mean is add all numbers and divide how many there is.)

Range=92-65=27 (Range is highest number take away lowest number)

Median: 65,65,65,66,77,77,77,77,85,85,85,85,92,92,92,92

so median is 81 (put numbers in order and find the middle number. if order is even add two numbers in middle and divide by two. If order is odd, find ONE number.)

Final answer:

The median of the sample exam scores is 81, the mean (or average) is 75.75, the mode is bimodal with values 85 and 92, and the range is 27.

Explanation:

Measures of Central Tendency and Variability

To determine the median of the provided exam scores, we must first arrange the scores in ascending order and then find the middle value. With 16 scores, the median will be the average of the 8th and 9th values in this ordered list. For the mean, we add all the scores together and then divide by the total number of scores. The mode is the score that occurs most frequently. The range is calculated by subtracting the smallest score from the highest score.

To simplify the expression 4 + (14 - 2), subtract 2 from 14, then add 4 to get the equivalent expression. The three equivalent expressions are: 20, -12, and 16.

To simplify the expression 4 + (14 - 2), we need to perform the operations inside the parentheses first. This means subtracting 2 from 14, which gives us 12. Then, we add 4 to 12, resulting in 16. Therefore, the expression 4 + (14 - 2) is equivalent to 16.

The three expressions that are equivalent to 4 + (14 - 2) are:

A. 4 - (-14 - 2) = 4 - (-16) = 4 + 16 = 20

B. (4 - 14) - 2 = -10 - 2 = -12

C. 4 - (-14) - (2) = 4 + 14 - 2 = 16

y = 0

x² + 2x-15 = 0

(x - 3) (x + 5) = 0

x = 3 or x = -5

The x-intercepts of the graph of the function are (-5,0) and (3,0).

Option C is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto-one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To find the x-intercepts of the graph of the function,

We need to set y = 0 and solve for x.

So we have:

x² + 2x - 15 = 0

Factoring this quadratic equation.

(x + 5) (x - 3) = 0

Setting each factor equal to zero.

x + 5 = 0 or x - 3 = 0

Solving for x.

x = -5 or x = 3

Therefore,

The x-intercepts of the graph of the function are (-5,0) and (3,0).
