I need to find the csc A, sec A, and cot A.
Step-by-step explanation:
the length of AB = √10²+7²=√149
so,
csc A = AB/BC = √149/ 7
sec A = AB/AC = √149/ 10
cot A = AC/BC = 10/7

Answer:
15
Step-by-step explanation:
you can add the absolute value of -7 with 8 so it's 15
The length of AD on the number line is,
⇒ AD = 15
What is mean by Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
We have to given that;
Number line is shown in figure.
And, The point A is at - 7 on number line.
The point D is at 8 on number line.
Hence, We get;
The length of AD on the number line is,
⇒ AD = | - 7 - 8 |
⇒ AD = | - 15 |
⇒ AD = 15
Therefore, The length of AD on the number line is,
⇒ AD = 15 units

You have $200 in a savings account and $100 in a checking
account. Each week, you add $50 to your savings account and $30 to your
checking account.
a. Write algebraic expressions that represent the amount of money in each
bank account after w weeks.
b. Write an expression in simplest form that represents the total amount of
money in both accounts after w weeks.
c. How much money do you have in both accounts after 5 weeks?
Answer:
a. Savings account: 200 + 50w Checking account: 100 + 30w
b. 300 + 80w
c. 700
Step-by-step explanation:
b. 200 + 50w + 30w + 100 Combine like terms. 300 + 80w
c. 300 + 80w. w=5. 300 + (80*5) = 300 + 400 = 700
find the distance between each pair of points
-6 -5 2 0
Hi, I'm happy to help!
To solve this, we need to find the distance in x coordinate values, y coordinate values, then use the Pythagorean Theorem to solve for the distance.
First, let's find the distance in x coordinate values. Our first x coordinate value is -6, and our second is 2. From here, we subtract.
-6-2=-8
Since we have a negative number, we use absolute value, which says how far the number is from 0.
I-8I
8
The distance in x coordinate values is 8.
Next, we find the distance in y coordinate values. our first y coordinate is -5, and our second is 0, now, let's subtract.
-5-0=-5
I-5I
5
The distance in y coordinate values is 5.
From here, we use the Pythagorean Theorem, which states that a²+b²=c².
This has to do with right triangles. Think about drawing a line down to the y coordinate of the other point, then to the x coordinate. Now, drawing a line straight from point to point. Now, you have a right triangle, and we are trying to find c, the direct distance of the line going from point to point. Let's say that our x distance is a, and our y distance is b.
Let's plug in the values:
8²+5²=c²
64+25=c²
89=c²
To find c, we need to find the square root of 89.
√89=c
9.433981132...=c
Since this number goes on forever, we need to round.
Rounding to the nearest thousandth:
9.434
Nearest hundredth:
9.43
Nearest tenth:
9.4
Depending on what the question asks, use one of these values.
To conclude, The distance between the two points is about 9.43 units.
I hope this was helpful, keep learning! :)

Grace and her dad are planning to attend the state fair. An adult ticket is $15.00. The price of an adult ticket is one half the price of a student ticket plus $8.00. Write an equation to determine how much Grace will pay for a student ticket.
one halfx + 8 = 15
one halfx − 8 = 15
one halfx + 15 = 8
one halfx − 15 = 8
Answer:
Option 1 is the correct equation.
Step-by-step explanation:
x = price of the student ticket.
One half price of x + $8 = adult ticket price ($15)
Answer:
The correct answer is A
Because taking the student ticket to be x
one half of x + 8 =15
Factor this polynomial completely.

-5/9 is rational, and its none of the other choices (integer, whole, irrational). So this value goes in the "rational" rectangle, and outside any other region.
The number [tex]-\sqrt{100}[/tex] turns into -10 after simplification. We see that this number is both rational and an integer. The best place for it is inside the "integer" circle. Note how this circle is entirely in the "rational" rectangle. We do not place it in the "whole number" circle because whole numbers are not negative.
The number [tex]\pi[/tex] is irrational since its decimal expansion goes on forever without any known pattern.
The number [tex]\sqrt{25}[/tex] simplifies to 5. This goes in the "whole number" circle.
Check out the diagram below.

2x2 + 2x - 1 when x = -3
Answer: 11
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
x = -3
Given expression
2x² + 2x - 1
Substitute values into the expression
=2(-3)² + 2(-3) - 1
Simplify exponents
=2(9) + 2(-3) - 1
Simplify by multiplication
=18 - 6 - 1
Simplify by subtraction
=12 - 1

In triangle ABC, m ZA = 47°, m ZB = 62°. m ZC =
a. 81°
b. 61°
C. 71
d. 51°
Answer:
m ZC = 71 degrees. Option C.
Step-by-step explanation:
Triangles always measure a total of 180 degrees.
47 + 62 + c = 180
109 + c = 180
c = 71
Answer:
71°
Step-by-step explanation:
The total angles in a triangle should equal 180°
a + b + c = 180
47 + 62 + c = 180
109 + c = 180
180 - 109 = 71
c = 71°
