When It asked to find sin, cos, tangent of a angleIf you finding the sin of a angle you must find the side that is Opposite then put it over the hypotenuse I'll do 3,6,7,8 for you.
For 3,The side that is opposite of c is 28 and the hypotenuse (which is the longest side of the triangle) is 35. So the answer is 28/35. or 4/5.
For 6, 32 is opposite of A and 40 is the hypotenuse so
32/40 or 4/5 is our answer.
For 7, 24 is opposite of Z and 40 is the hypotenuse so
24/40 or 3/5 is the answer.
For 8, 14 is opposite of Angle C and 50 is our hypotenuse so
14/50=7/25 is our answer
COS
To find cos it is adjacent/hypotenuse
For 2 the adjacent side to C is 16 and the hypotenuse is 34. so our answer is 16/34 or 8/17.
For 5, the adjacent side is 30 and the hypotenuse is 34 so our answer is 30/34 or 15/17
For 9, the adjacent side is 24 and hypotenuse is 30 so our answer is 24/30 or 5/6.
TAN
TO FIND TAN, it is Opposite/Adjacent
4, the opposite side is 32 and the adjacent is 24 so our answer is 32/24 or 4/3.
10, the opposite side is 27 and the adjacent is 36 so our answer is 27/36 or 3/4

A circle has its center at the point (1, -3) and goes through the point (-3, 0). Using this information, write the equation for the circle.
Answers
Answer:
(-3-1)^2+(0+3)^2=r^2
radius is 5 units
Step-by-step explanation:
(x-h)^2+(y-k)^2=r^2
We know values of all variables except r at the moment.
h is the x-coordinate of the center of the circle, and k is the y-coordinate.
x and y are coordinates of a point the circumference touches.
From there, just plug in the numbers and solve!

The points (4, 1) and (x, -6) lie on the same line. If the slope of the line is 1, what is the value of x?
Answers
Answer:
x = -3
Step-by-step explanation:
using the slope formula y2 - y1/x2 - x1 = 1 so
-6 - 1 / x - 4 = 1, so -7/-7 = 1 so x has to be -3 to make the bottom = -7

If the simple interest on $8000 for 3 years is $540, what is the rate of interest per annum?
Answers
Answer:
2.25%
Step-by-step explanation:
I = Prt
Given:
I = 540
P = 8000
t = 3
Solve for r:
I = Prt
r = I/(Pt)
r = 540/(8000 * 3)
r = 540/24000
r = 0.0225
Rate in percentage form:
0.0225 * 100 = 2.25%

Step-by-step explanation:
how you would solve this is 5 plus 3 plus 2 which will equal 10 (this ten will be your denominator) after that you look at how many blue sections there are (5). so 5 out of 10 of them are blue so your fraction would be 5/10. then you will reduce the fraction to 1/2. the question wants you to put this in decimal form so you will divide the 1 by 2 so in decimal form this is 0.5.

PLZZ HELP find area of square KLMN?
Answers
Hello! The area of square KLMN is 25 cm²
Make sure to read an explanation for better understanding to the problem.
Any questions about my answer and explanation can be asked through comments.
Step-by-step explanation:
Since the square has same length for both sides. We can proceed side × side formula. Our side is 5 because if we count these small squares or grids, we'd get 5 for both sides.
Therefore 5 × 5 = 5² = 25 cm².
We can also use Calculus to solve the problem by using Integration.
Because both lines are horizontal, they are constant function. That means they are in the form of y = b where b is a constant.
A line that passes through (a,4) where a is all real numbers. The equation is y = 4
A line that passes through (c,-1) where c is all real numbers. The equation is y = -1
Therefore,
[tex] \large{ \int^{b}_a f(x) dx+ \int^{b}_a g(x)dx} \\ \large{ \int^{2}_{ - 3} (4)dx+ \int^{2}_{ - 3} ( - 1)dx}[/tex]
Because y = -1 is below x-axis. Therefore,
[tex] \large{ \int^{2}_{ - 3} 4 dx+ \int^{2}_{ - 3} 1dx} \\ \large{ (4x)^{2}_{ - 3} + (x)^{2}_{ - 3} } \\ \large{8 - ( - 12) + 2 - ( - 3)} \\ \large{8 + 12 + 2 + 3 = 25}[/tex]

There are 14 penguins on the rocks. Half as many are swimming. How many are in the water? How many in all?
Answers
Answer:
7 penguins are in the water.
21 penguins in all.
Step-by-step explanation:
14 penguins on the rocks.
Half of them equals 7 are in the water swimming.
7 + 14 = 21
7 penguins are in the water.
21 penguins in all.
The number of penguins in water = 7 penguins
The total number of penguins = 21 penguins
Word problems in mathematics involve a crucial understanding of solving real-life cases with the use of arithmetic operations.
From the information given:
There are 14 penguins on the rock.Half as many are swimming implies that: 7 of them are swimmingThus, the number of penguins in water = 7 penguins
The total number of penguins overall = penguins in water + penguins on the rock
The total number of penguins overall = 7 + 14
The total number of penguins overall = 21 penguins
