20 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse h is equal to the sum of the squares on the other 2 sides, that is
h² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )
h = [tex]\sqrt{400}[/tex] = 20

3 m
a. 12
b. 3
d. 1.3
075
Evaluate m + n for m - 9 and n = 7.
A 2
C 63
B 16
D 97
Answer:
The only thing I can think of is -2.
Step-by-step explanation:
-9 + 7 = -2
I'm not sure if you wrote the questions or the answers wrong, but if I'm reading it right the answer should be -2, not 2. Unless you meant to write 9 + -7, in which case the answer would be 2.

Which represents an even function?
A. y = cos(x)
B. y = sin(x)
C. y = tan(x)
D. y = cot(x)
NVM I DID IT
ANSWER: A
Answer:
A. y=cos(x)
Step-by-step explanation:
I just want the points. im taking the quiz rn.
From the given options, the only even function is the cosine function, so the correct option is A.
Which of the options is an even function?First, an even function is a function with the property:
f(x) = f(-x)
So these functions are symmetrical across the y-axis.
Is ratter easy to remember that the sin function is actually odd, this means that:
sin(-x) = -sin(x).
Then the tangent function (and the cotangent function) are also odd, because:
tan(x) = sin(x)/cos(x).
In the other hand, for the cosine function we have:
cos(-x) = cos(x)
And as shown in the graph below, it is symmetrical across the y-axis.
Then we conclude that the correct option is A.

what is the square of a sum of six and a number in algebraic expression form?
Given parameters:
Let us solve this problem step wisely;
We are looking for the square of a numberLet the number = x
the sum of this number and 6 is squared6 + x
Squaring gives;(6 + x)²
The algebraic interpretation is (6 + x)²
In problems like this, it is best to first choose a variable and then solve following sentence by sentence.
2. The Perimeter of a square is P. Which equation could be used to find its area (A)?
a. A = P2
b. A = (p/4)^2
c. A = 4P
d. A = (√p)^2
Answer:
A = (P/4)²
Step-by-step explanation:
Given
Perimeter = P
Required
Determine the area
First, we need to calculate the sides of the square using:
[tex]P = 4L[/tex]
Where L represents the length of the side
Make L the subject
[tex]L = \¼P[/tex]
Area is calculated as thus:
[tex]Area = L\²[/tex]
Substitute ¼P for L
[tex]Area = (\¼P)\²[/tex]

Find the distance between the points (2,0) and (-4,6)
Answer:
let's see what to do buddy...
Step-by-step explanation:
We have this equation to find the distance between two points :
a = ( 2 , 0 ) and b = ( -4 , 6 )
[tex]distance = \sqrt{ {( \: y(b) - y(a) \: })^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ [/tex]
Now just need to put the coordinates in the equation :
[tex]distance = \sqrt{ ({6 - 0})^{2} + ({ - 4 - 2})^{2} } \\ distance = \sqrt{ {6}^{2} + ({ - 6})^{2} } = \sqrt{36 + 36} \\ distance = \sqrt{36 \times 2} = 6 \sqrt{2} [/tex]
And we're done.
Thanks for watching buddy good luck.

Please help!!! I really don’t get this only I get where the 3 are but please help me for the 4/5 and -0.4!
Answer:
-0.4 should be in between 0 and -0.5, however be as close to -0.5 as possible while not being ON -0.5.
3 4/5 should be in between 3 and 4, so you can split 4/5 into 8/10 which are equal to each other. Then you can pretend to split the 3 and 4 gap into 10 equal pieces. After you split the gap, count 8 parts to the left of 3.
