Answer:
cos(A) = 12/13
Step-by-step explanation:
There are several ways to remember trigonometric functions, but my personal favorite is:
SOH - CAH - TOA
Where Sin(angle) = Opposite/Hypotenuse
Cos(angle) = Adjacent/Hypotenuse
and Tan(angle) = Opposite/Adjacent
The opposite is the side of a triangle that does not form part of the angle. E.g. for angle A the opposite is 5, for angle B the opposite is 12.
The hypotenuse is the longest side of the triangle, or the opposite in relation to the right angle (signified here by the little red box in the bottom left).
The adjacent is the side that isn't the hypotenuse, but is still next to a given angle. E.g. the adjacent for angle A is 12, and the adjacent for angle B is 5.
The cosine of angle A is the adjacent of angle A divided by the hypotenuse. The side adjacent to A is 12, and the hypotenuse is 13. Therefore, the cosine of angle A is 12/13.

What you are saying does not make sense for a scale factor of 1. If it were a scale factor of one, it would still be 64 lbs. which is not a option.

The equivalent expression of [tex]w^{4} -36[/tex] is [tex](w^{2} -6)(w^{2} +6)[/tex].
What is equivalent expression?Equivalent expressions are expressions that work the same even though they look different.
According to the given question.
we have an expression [tex]w^{4} -36[/tex]
The equivalent expression of the above expression can be given by
[tex]w^{4} -36[/tex]
⇒ [tex](w^{2}) ^{2} -(6)^{2}[/tex]
⇒[tex](w^{2}-6)(w^{2} +6)[/tex] (by using the property [tex]a^{2} -b^{2} = (a-b)(a+b)[/tex] )
Hence, the equivalent expression of [tex]w^{4} -36[/tex] is [tex](w^{2} -6)(w^{2} +6)[/tex].
Thus, option D is correct.

Step-by-step explanation:
I used the elimination method to solve this. so we can see that there is 100 boxes and we need to 75 to be shaded. only C and D have 75 squares shaded so we can eliminate A and B. now we have to divide by 5. Square C is divided 3 times while square D is divided 5 times, so square D is correct.

How do you find the distance between points (5,1), (4,0)?
Answers
Answer:
To find the hypotenuse, you would use the formula a^2 + B^2 = C^2
That is the formula for the pythagorean theorem.
I suggest you first plot it on a graph, then could the units on the sides that make up the legs.
When you plot it, the legs are both 1 unit.
so it would be, following the formula:
1^2 + 1^2 = c^2
1 x 1 + 1 x 1 = c^2
2 = c^2
Then you square root:
√2 = √c^2
1.41421356 = c
1.41421356 rounded to the nearest tenth is 1.4.
So the length of (5,1), (4,0) is ≈1.4

Answer:

Step-by-step explanation:
We solve using the Trigonometric function Cosine
cos θ = Adjacent/Hypotenuse
θ = 40°
Hypotenuse = 19
Adjacent = x
Therefore,
cos 40 = x/19
Cross Multiply
x = cos 40 × 19
x = 14.554844419
Approximately to the nearest tenth,
x = 14.6

Answers
Answer:
A) [tex]x = y^{2}[/tex]
Step-by-step explanation:
An equation is a function of [tex]x[/tex] when [tex]x[/tex] is the independent variable, that is:
[tex]y = f(x)[/tex] (1)
Where [tex]y[/tex] is the dependent variable.
According to this, [tex]x = y^{2}[/tex] does not represent a function of [tex]x[/tex], since the independent variable is a function of [tex]y[/tex], that is, [tex]x = f(y)[/tex]. Therefore, the correct answer is A.

1) Javier wants to replace the carpet in the two
bedrooms of his home. Bedroom 1: is rectangular
in shape that has a width of 10ft and length of
8.5ft. Bedroom 2: is rectangular in shape that has
a width of 11.75ft and length of 13.25ft. If the
carpet he wants to buy is $2.83 per square foot,
then how much will it cost for both rooms?
a. $85.00
b. $155.69
c. $240.69
d. $681.15
Answers
Answer:
d. $681.15
Step-by-step explanation:
Bedroom 1:
Width = 10 ft
Length = 8.5 ft
Area of bedroom 1 = length × width
= 10 ft × 8.5 ft
= 85 ft²
Bedroom 2:
Width = 11.75 ft
Length = 13.25 ft
Area of bedroom 2 = length × width
= 11.75 ft × 13.25 ft
= 155.6875 ft²
Total carpet in the two bedrooms = 85 ft² + 155.6875 ft²
= 240.6875 ft²
If the
carpet he wants to buy is $2.83 per square foot, then how much will it cost for both rooms?
Total cost for both rooms = Total carpet in the two bedrooms × cost per square foot
= 240.6875 ft² × $2.83
= $681.145625
Approximately $681.15
1) One baseball team won 20 games throughout their entire season. Of all their games, this
team won 62.5% of them. Given this, how many games in total did this baseball team play
Answers
Answer: 32 matches
Step-by-step explanation:
Let the games in total that the baseball team played be represented by x.
Based on the information given in the question, we can form an equation as:
62.5% × x = 20
62.5/100 × x = 20
0.625 × x = 20
0.625x = 20
x = 20/0.625
x = 32
The team played a total of 32 matches.

Answers
Answer: 68
Step-by-step explanation:
Simplifying the expression:
= 8a² + 6b + 9a² + 9b² + 3b
Collect like terms
= 8a² + 9a² + 6b + 3b + 9b²
= 17a² + 9b + 9b²
We then substitute a=2,b=−1.
= 17a² + 9b + 9b²
= 17(2)² + 9(-1) + 9(-1)²
= 68 -9 + 9
= 68
