Answer:
We know that, for a right triangle:
Cos(A) = (adjacent cathetus)/hipotenuse
sin(A) = (opposite cathetus)/Hipotenuse.
If we are in a right triangle inside the unit circle, we have that hypotenuse = 1.
Now, when you draw the unit circle, now from the center of the axis you must draw a straigth line (that forms an angle of 120° with the x-axis), and in the point where it cuts the unit circle we do 2 things.
from this point, you can draw a parallel line to the y-axis, the point where this line touches the x-axis is the value of the cosine.
Now you draw a line that is parallel to the x-axis (remember that the line must pass trough the point of before), the point where this line cuts the y-axis is the value of the sine
You should get:
sin(120°) = 0.87
cos(120°) = -0.5
find the missing letter which is n. perimeter is 108 inches and width is 18 inches
The perimeter can be found by using the formula: P = 2w + 2h
w = width
h = height
P = perimeter
We are given the perimeter of 108 inches.
We are given the width of 18 inches.
Substitute in the formula.
108 = 2(18) + 2h
108 = 36 + 2h
Solve for h.
108 = 36 + 2h
108 - 36 = 36 - 36 + 2h
72 = 2h
72/2 = 2h/2
36 = h
Therefore, the length of the missing side is 36 inches.

I’m Mrs. Miller’s last will and testament, she leaves half of her money to her cat, Maggie, and half that amount to her dog, Chop Chop. She leaves a sixth to her goldfish, Bruno. And she leaves the remainder of her money, $1000, to her parakeet, Philomena. How much money is she leaving in total?
Answer:
1/2 + 1/4 + 1/6 = 3/4 + 1/6 = 11/12 .
1/12 = 1000

true?
O A. The domain is (1,00), and the range is all real numbers.
O B. The domain is (1,0), and the range is [5,).
O C. The domain is (-1,0), and the range is all real numbers.
O D. The domain is all real numbers, and the range is [5,).
Answer:
C. The domain is (-1,+∞), and the range is all real numbers.
Step-by-step explanation:
The domain is (-1,+∞) because the expression ln(x+1) exists only if x>-1
and the range is all real numbers.

Rectangle A measures 3cm by (8x - 7)cm and rectangle B measures 4cm by (5x + 2)cm. Area of both rectangles is equal. Create the equation and find the value of x.
please help me i will mark you brainliest
Answer:
Equation: 3 (8x - 7) = 4 (5x + 2)
Value of x =7.25 cm
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a rectangle: width x length
Replacing with the values given:
Area A = 3 (8x - 7)
Area B = 4 (5x + 2)
Since both areas are equal:
Area A = Area B
So:
3 (8x - 7) = 4 (5x + 2)
Solving for x:
24x -21 = 20x+8
24x-20x =8+21
4x =29
x =29/4=7.25 cm

The scatter plot below can be used to find the approximate rate at which water flows through a garden hose. The line of best fit for the scatter plot can be described by the equation y = 4/5x. If the rate, in gallons per minute, continues, approximately how many gallons of water will flow from the hose in 45 minutes?
36
39
56
24
Answer:
[tex]36\ \text{gallons per unit}[/tex] will flow from the hose in 45 minutes.
Step-by-step explanation:
The line of best fit for the scatter plot can be described by the equation :
[tex]y=\dfrac{4}{5}x[/tex]
y is amount of water in gallons
x is time
When x = 45 minutes, put x = 45 in above formula as :
[tex]y=\dfrac{4}{5}\times 45\\\\y=36\ \text{gallons per unit}[/tex]
So, [tex]36\ \text{gallons per unit}[/tex] will flow from the hose in 45 minutes.

If the zeros of a quadratic functions are -2 and 4, which graph could represent the function?
Answer:
The Graph having the X-intercepts of (-2,0) and (4,0)
Step-by-step explanation:
The zeroes of the function is the X-intercept.
The graph that represent the function should be that it contains the x-intercept of (-2,0) and (4,0)
What is x-intercept?
Here the x-intercept means the x-coordinate of the point at which the line, curve, the surface should be intersected at the x-axis.
Since there are the zeros of the quadratic equation that contains -2 and 4
So here we can say that The graph that represent the function should be that it contains the x-intercept of (-2,0) and (4,0)

If you're good at logarithms please help me with question two d and h thanks
show full working out ;)
Answer:
d. -0.301
h. 1.38
Step-by-step explanation:
Loga0.5 = loga2^-1
= -1(loga2)
= -1 (0.301)
= -0.301
Loga24 = loga(2^3 x 3)
= loga2^3 + loga3
= 3 (loga2) + loga3
= 3 (0.301) + (0.477)
= 1.38

The area of the base of a triangular pyramid with faces that are equilateral triangles is 64 ft squared. Can you find the surface area of the pyramid? Explain. Here are the choices
A. No, because the area of the base of a pyramid is not related to the area of its faces, so the surface area cannot be found without more information.
b. No, because the base of a pyramid with equilateral triangle faces does not necessarily have the same area as its equilateral faces.
C.Yes, because the area of the base of a triangular pyramid with equilateral triangles for faces is the same as the area of each face.
D.Yes, because the area of the base will be the edge length of each face, which can be used to find the area of each face
Answer:
C.
Step-by-step explanation:
Yes, because the area of the base of a triangular pyramid with equilateral triangles for faces is the same as the area of each face.
So the surface area is 64 * 4 which is 256
