In triangle ABC, angle C is a right angle. Find the value of the trig function indicated. Find tan A if c = 17 and a = 8
Answer:
Step-by-step explanation:
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.

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.

Answer:
The integers are
5 and 7
Step-by-step explanation:
Let
x ---> the first consecutive odd integer
x+2 ---> the second consecutive odd integer
we know that
The algebraic expression that represent this situation is
[tex]x(x+2)=x+30[/tex]
solve for x
[tex]x^2+2x=x+30\\x^2+2x-x-30=0\\x^2+x-30=0[/tex]
Solve the quadratic equation
The formula to solve a quadratic equation of the form
[tex]ax^{2} +bx+c=0[/tex]
is equal to
[tex]x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}[/tex]
in this problem we have
[tex]x^{2} +x-30=0[/tex]
so
[tex]a=1\\b=1\\c=-30[/tex]
substitute in the formula
[tex]x=\frac{-1\pm\sqrt{1^{2}-4(1)(-30)}} {2(1)}[/tex]
[tex]x=\frac{-1\pm\sqrt{121}} {2}[/tex]
[tex]x=\frac{-1\pm11} {2}[/tex]
[tex]x=\frac{-1+11} {2}=5[/tex]
[tex]x=\frac{-1-11} {2}=-6[/tex] ---> is not a odd integer
For x=5
The numbers are
[tex]x=5\\x+2=7[/tex]
so

If f(x) =4x^2 + 1 and g(x) =x2 -5, find (f+g)(x)
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]

F(x)=12x+1
Find f(4)
f(4) is 49
Explanation:
Given:
f(x) = 12x + 1
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

carol invests 6250 at a rate of 2 per year compound interest calculate the total amount carol has after 3 years
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:
A is the amount of money accumulated after n years, including interest. P is the principal amount (the initial amount of money). r is the annual interest rate (decimal). n is the number of times that interest is compounded per year. t is the time the money is invested for in years.
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.

What is the median?
What is the mean?
What is the mode?
What is the range?
Answer:
Step-by-step explanation:
Mode=77&92&85 (mode is most common number)
Mean= 85+92+65+85+65+85+77+92+92+66+77+92+77+77+65+85=1277
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.
Calculating the Median
Arranged Scores: 65, 65, 65, 66, 77, 77, 77, 77, 85, 85, 85, 85, 92, 92, 92, 92 Median: (77 + 85)/2 = 81Calculating the Mean
