Answer:
The relationship between the two is that they are equal.
Step-by-step explanation:
Since y = cosx is a even function, that means that cosx = cos(-x). Therefore, cos 90 degrees = cos -90 degrees.
We can also test this out:
cos 90 = 0
cos -90 = cos 270 = 0
Therefore, this came to the same conclusion as our first solution.

What is 8b - ab + 7a subtracted from 3a - 9ab + b?
Answer:
10a-10ab-7b
Step-by-step explanation:
i dont feel like putting the steps but ik this is correct
The answer is -4a -8ab -7b after subtracting 8b - ab + 7a from 3a - 9ab + b.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have two expressions:
8b - ab + 7a and 3a - 9ab + b
After subtracting:
= (3a - 9ab + b) - (8b - ab + 7a)
= -4a -8ab -7b
Thus, the answer is -4a -8ab -7b after subtracting 8b - ab + 7a from 3a - 9ab + b.

Answer:
A Subtract the bottom equation from the top equation.B Add the equations.Step-by-step explanation:
The x-terms are the same in each equation, so subtracting one equation from the other will eliminate the x-variable.
The y-terms are opposites in the two equations, so adding the two equations will eliminate the y-variable.
Both strategies (subtracting, adding) are applicable to this system of equations.

Answer:
1. 561%
2. 1
3. 7/80
4. 31.25%
5. 6%
Step-by-step explanation:
To start off, lets learn how to convert decimals to percent's.
Converting is actually not too hard. All you need to do is multiply the decimal by 100.
So 5.61 * 100
That would be 561 and then you add a percent sign to the end.
To convert a percent to a decimal is just the opposite of what we just did. Simply divide the percent by 100.
So 100% /100
A number divided by itself is 1
So 100% = 1
To make this problem easier, you can convert the fraction to a decimal.
8 3/4 = 8.75%
Now divide it by 100
8.75/ 100
0.0875
Now just convert it back to a fraction.
0.0875 = 7/80
Convert to a decimal.
5/16 = 0.3125
Multiply by 100
31.25
add percent sign
31.25%
Last one.
Convert to decimal
3/5 = 0.6
Multiply by 100
6%

Two angles of a Triangle measure 55° and 22° What is the measure of the third angle of the triangle
A. 15°
B. 90°
C. 105°
D. 285°
Answer:
c would be the closest
Step-by-step explanation:
All triangles equal 180*. so if you combine the 2 angles, which adds up to 77* then that would leave the third angle to be 103* but since that isnt an option choose c since its the closest.
The measure of a square side is 1.2 feet what is the perimeter of the square inches
Answer: It would be 4.8

Answer:
45
Step-by-step explanation:
Answer:
a = 45
b = 15
Step-by-step explanation:
From the information given, you can deduce that both ΔPQR and ΔPSR are isosceles triangles that share base PR. This means that ∠a = ∠SRP because the base angles of an isosceles triangle are always congruent.
Because the vertex of ΔPSR is 90°, you know that the base angles add up to 90 because 180(sum of a triangle's angles) - 90 = 90. 90/2 = 45, so a = 45.
To find b, you need to subtract the base angle of ΔPSR from the base angle of ΔPQR. ΔPQR's base angle is 60, because 180 - 60 = 120 and 120/2 = 60. 60 - 45 = 15, so b = 15.

what is the value of tan360°?
Answer:
tan360°= 0
I hope this helps you
Answer:
please mark as brainliest
Step-by-step explanation:
tan360°
= cot (90°-360°) = cot -270°
-tan360°
= tan (-360°) = -tan 360°
= cot (90°+360°) = cot 450°
= tan (180°-360°) = tan -180°
Mr Avalon's cousin's Kurt and rod started their own business curtain rods curtain rods they sell curtain rods for $5 each they rent a store in the mall for their business for $2,500 per month how many curtain rods must they sell to earn a profit of$ 3750?
Answer:34.3 N and 15.7 N
Explanation:
= force on the left end of the rod
= force on the right end of the rod
M = mass of Halloween decoration = 3 kg
= weight of the Halloween decoration = Mg = 3 x 9.8 = 29.4 N
m = mass of rod = 2.1 kg
= weight of the rod = mg = 2.1 x 9.8 = 20.6 N
From the force diagram, using equilibrium of torque about A
(AB) + (AC) = (AD)
(29.4) (21) + (20.6) (57) = (114)
= 15.7 N
Using equilibrium of force along the vertical direction
+ = +
15.7 + = 29.4 + 20.6
= 34.3 N

Here is a triangle with the height on the side of the triangle. Use the formula: (1/2)*(Base)*(Height) to find the area of the triangle at the left.
(If one square on the graph = one centimeter)
b = 10cm
b = 10cmh = 10cm
Area:
[tex] = \frac{1}{2} \times b \times \: h[/tex]
[tex] = \frac{1}{2 } \times 10 \times 10[/tex]
[tex] = \frac{1}{2} \times 100[/tex]
[tex] = 50 {cm}^{2} [/tex]

for a coordinate proof concerning an isosceles triangle, which coordinates might be easiest to use?
Answer:
(0,0) , (a,b) , (2a,2b) is the answer
Step-by-step explanation:
for a triangle to be isosceles, then two sides must be equal
To picture this, if we have a point at the origin, with coordinate (0,0); we can have the coordinates of the other points being the same so as to make the distance from the origin the same
Then from here, we can get that the length of the two sides are equal
From what we have, option 4 can be correct
This is because , finding the distance between two points is;
D = √(x2-x1)^2 + (y2-y1)^2
From what we have
The distance between (0,0) and (a,b) will give same answer for the distance between (a,b) and (2a,2b)

Answer:
x = xStep-by-step explanation:
The first step here is to use the distributive property to make the first equation back into a polynomial.
The way we do this is by multiplying each term on the inside of the parentheses by the -2 on the outside.
-2 x x = -2x
-2 x 3 = -6
So, our new equation reads: -2x - 6
-2x - 6 = -2x + 3 - 9
Our next step is to subtract the 9 from 3.
-2x - 6 = -2x - 6
We add 6 to each side
-2x = -2x
x = x
0 = 0
slope=6,(3,7) in standard form
If g(x) = 2x2 + 6x + 5, use synthetic division to find g(-5).
=================================================
Explanation:
Check out the image below. I've posted the synthetic division table. The value at the very end of the bottom row is the remainder. By the remainder theorem, this is exactly the value of g(-5).
Recall the remainder theorem says: If you divide p(x) by (x-k), then the remainder is p(k). In this case, k = -5 is our test root which is the value placed in the box on the left.
As a way to check the answer, we can say
g(x) = 2x^2 + 6x + 5
g(-5) = 2(-5)^2 + 6(-5) + 5
g(-5) = 25
So the answer is confirmed.
