Which of the following is equal to angle C?A.cos (a/c)
B.sin (a/c)
C. tan^-1 (c/a)
D. cos^-1 (c/a)

Answers

Answer 1

Answer: tangent = opposite/adjective
tan(C) = c/a
We can use an inverse ratio to find the measure of <C.
C = tan^-1(c/a)

Answer 2

Answer: tan(C)=O/A=c/a

Therefore:

C=tan⁻¹(c/a)

So your answer is C.

How do i slove x+ 3y=-24 to a slope intercept

Answers

To solve the equation x + 3y = -24 for the slope-intercept form, you need to isolate y. First, subtract x from both sides to get 3y = -x - 24. Then, divide both sides by 3 to get y = (-1/3)x - 8. So, the equation is now in slope-intercept form, y = mx + b, where m is the slope (-1/3) and b is the y-intercept (-8).

Answer:

y = -(1/3)x - 8

Step-by-step explanation:

Slope intercept form is defined as y = mx + b. Therefore, we need to start by isolating the y variable. To do this, we can subtract x from both sides:

3y = -x - 24

Next, we need to divide both sides by 3 so that y is singular:

y = (-1/3)x - 8

The original equation is now in slope intercept form.

Slope = -1/3

Intercept = -8

Renauld has to pay 2 percent in closing costs and 14 percent for the down payment on a purchase of $170,500. Over the life of his loan, he will pay $163,021.87. What is the total cost of his house?. A. $166,431.87. B. $186,891.87. C. $190,301.87

Answers

The correct answer is:

C. $190,301.870.

Explanation:

Paying 14% down is 0.14(170500) = $23,870.

2% closing costs are 0.02(170500) = $3410.

Adding these to the amount he pays on the loan, $163,021.87, we have:

163021.87+23870+3410 = 190301.87

The totalcost of Renauld’s house is $190,301.87. The technique here is to know the value of the closingcosts and the down payment so the correct answer between all the choicesgiven is the last choice or letter C. I am hoping that this answer hassatisfied your query about this specific question.

Daniel wants to have a 90 average in his math class at the end of the year. He is trying to determine what he needs to get on his final exam, which accounts for 10% of his grade, for this to work. Tests are weighted 50% of the grade, and he currently has a 85 for his test average; quizzes are weighted 15% of his grade, and he currently has a 95 quiz average; homework is weighted 15% of his grade and he currently has a 98 homework average; and projects are weighted 10% of his grade and he currently has a 92 project average. What is the lowest whole percentage Daniel can make on his final exam for him to end up with a 90 in the class?

Answers

Exam + Tests + Quizzes + HW + Projects = 90

Exam = 10% * grade (x) = 0.1 * x

Tests = 50% * 85 = 0.5 * 85 = 42.5

Quizzes = 15% * 95 = 0.15 * 95 = 14.25

HW = 15% * 98 = 0.15 * 98 = 14.7

Projects = 10% * 92 = 0.1 * 92 = 9.2

Exam + Tests + Quizzes + HW + Projects = 90

(0.1 * x) + 42.5 + 14.25 + 14.7 + 9.2 = 90

(0.1 * x) + 80.65 = 90 (subtract 80.65 from each side)

(0.1 * x) = 9.35 (divide 0.1 from each side)

(0.1 * x)/0.1 = 9.35/0.1

x = 0.935

The answer is 93.5%

How do you find the f(x) inverse using fractions?

Answers

for example.. 1) switch places of x and y. x=3y+1 x=3 y +1
2) try to solve for y. so multiply the denominator by x to get rid of it
3) after multiplying, ur left with xy+x=3 x y + x=3
4) that converts to 2xy= x y =3
5) get rid of 2x on left by placing it on the right
6) convert y to inverse function
