Answer:225
Step-by-step explanation:
Complete the steps to derive the cofunction identity.
Answer:
See below
Step-by-step explanation:
In order to derivate the cofunction identity, we will use the difference identity for sine.
[tex]\boxed{\sin(\alpha-\beta ) =\sin(\alpha )\cos(\beta ) - \cos(\alpha )\sin(\beta ) }[/tex]
[tex]\sin \left(\dfrac{\pi}{2} - x\right) =\sin \left(\dfrac{\pi}{2}\right)\cos(x) -\cos\left(\dfrac{\pi}{2}\right) \sin(x)[/tex]
Once
[tex]\sin \left(\dfrac{\pi}{2}\right) = 1[/tex]
[tex]\cos\left(\dfrac{\pi}{2}\right) = 0[/tex]
[tex]\sin \left(\dfrac{\pi}{2} - x\right) =1 \cdot \cos(x) -0\cdot \sin(x)[/tex]
[tex]\sin \left(\dfrac{\pi}{2} - x\right) = \cos(x)[/tex]

How are the slope formula and finding slope using "rise over run" related?
Answer:
they are the same thing
Step-by-step explanation:
Answer:
They are practically the same thing but if you want to get technical then they are related because A slope a measure of steepness. A line with a large slope, such as 25, is very steep. A line with a small slope, such as 1 /10 is very flat. So this means it will rise over run if that makes sense.

Suppose that 24 inches of wire costs 96 cents.
At the same rate, how much (in cents) will 47 inches of wire cost?
Answer:
Step-by-step explanation:
24inches = 96 cents
To find the cost of 1 inch, divide 96 cents by 24.
1 inch = 96/24 = 4 cents
Then to find the cost of 47 inches, multiply by 4.
47 inches = 47 x 4 = 188 cents.

Hank wants to add a row of tile to his kitchen wall. The space is 5.75 feet long. He plans to put a \frac {3}{4} 4 3 –foot yellow tile in the center. He'll fill the rest of the space with blue tiles that are 3 inches long. How many 3-inch blue tiles will he need?
Answer:
He will need 20 3-inch blue tiles
Step-by-step explanation:
Here, the total space to fill is a length of 5.75 ft
The tiles to place at the center has 3/4 ft which is same as 0.75 ft
The length left unfilled will be 5.75 - 0.75 = 5 ft
Now we want to know the number of 3 ft tiles needed to fill up this length;
Mathematically, we know that
1 ft = 12 inches
So 5 ft will be 5 * 12 = 60 inches
So the number of 3 inch tiles needed to fill this length will be 60/3 = 20 tiles

What is the minimum angle of rotation (in degrees) that will carry the six-sided star onto itself?
Answer:
The angle of rotation pf a six sided star, that will carry the six sided star onto itself is 60°
Step-by-step explanation:
The angle of rotation that will carry a six sided star onto itself is the angle between two adjacent lines of symmetry of the six sided star
Given that there are three lines of symmetry of the six sided star, and each line intersect with the next line at the center of the figure, the angle between two adjacent lines of symmetry = 360°/(2 × 3) = 60°
Therefore, the angle of rotation pf a six sided star, that will carry the six sided star onto itself = 60°.
Find the slope of the line passes through (1,4) and (9,1)
Answer:
-0.375
Step-by-step explanation:
Way one(the harder one):
Let the line which passes through (1,4) and (9,1) be f(x)=kx+b
Sub (1,4) and (9,1) in and we get [tex]\left \{ {{4=1k+b} \atop {1=9k+b}} \right.[/tex]
=> (9k+b)-(k+b)=1-4
8k=-3
k=-3/8 or -0.375
Therefore the slope of the line is -3/8 or -0.375
Way two(the easier one):
k= [tex]\frac{change in y}{change in x}[/tex] = [tex]\frac{1-4}{9-1}[/tex] = -[tex]\frac{3}{8}[/tex]
Tap A fills 10/11 of a bottle in a minute. Tap B fills 3 4/5 times as many bottles as Tap A in a minute. Find the number of bottles Tap B fills in a minute.
Answer:
3 5/11
Step-by-step explanation:
Tap A's rate is (10/11) bottle/min.
Tap B's rate is 3 4/5 = 19/5 times that of tap A. Then tap B's rate is ...
(19/5)(10/11) bottles/min = 38/11 bottles/minute
Tap B fills 3 5/11 bottles in a minute.

Which of the following is a solution of the equation -5x + 2 = -13: answers: x=-9, x=75 x=3 x=-3
Answer:
x= 3
Step-by-step explanation:
1. -5(3) + 2 = -13
2. -15 + 2 = -13 A positive times a negative will always equal a negative
3. -13 = -13 Whenever you add anything to a negative number, the
number becomes smaller
Ex: -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, ...........
Although the number itself becomes smaller, its value
becomes bigger

Which of the capital letters G, I, J, L, or Q has at least one line of symmetry?
Letters that have lines of symmetry is : I
What is reflectional symmetry?Consider a plane. Let a design or shape on that plane. Now consider an axis. If we think of that axis as a mirror, and on the opposite side of that axis create the image of the shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.
The lines of symmetry can be found as vertical or horizontal. Letters O, H, I. X have 2 lines of symmetry and other have 1.
At least one line of symmetry have letters:
A, B, C, D, E, H, I, M, O, T, U, V, W, X, Y ( you can choose one ).
The letter G has a no axis of symmetry and letter L has a horizontal axis of symmetry.
The letter I is the right one because it is a half and both look the same.
