Answer:
A
Step-by-step explanation:
12 / tan 42 = 13.32......
12 / sin 27 = 26.43....
26.43² - 12² = 552.24....
square root of 552.24... = 23.5
23.5 - 13.3 = 10.2
Find the value of the variable. If your answer is not an integer, leave it in simplest radical form.
Answer:
[tex]\frac{13}{\sqrt{2}}[/tex] or 9.19 (approximately). I am confused how the question is asking for it to be typed, so it might be this: [tex]\frac{13}{\sqrt{2}}[/tex] , but if you cannot type that in, then maybe it is sin(45) * 13.
Step-by-step explanation:
The three main trigonometric ratios are: sine (o/a), cosine (a/h), or tangent (o/a) depending on the given. To help you remember them, you can use the saying SOH CAH TOA, which is sin = opposite/hypotenuse, cosine = adjacent/hypotenuse, and tangent = opposite/adjacent.
In this problem, we are going to use one that has the hypotenuse, which rules out tangent, and leaves us with sine or cosine. Since, we are given the hypotenuse and the opposite side (from angle 45), we will be using sine. Then we just need to set up the trigonometric ratio:
sin (45) = x/13
Then, you need to get x by itself, so you multiply 13 on each side, which leaves you with:
x = sin(45) * 13 = 9.19 (approximately)
This could also be seen as a special right triangle, where the hypotenuse is [tex]x\sqrt{2}[/tex], and the two sides are x.
So, to find the value of x, you could also do this: 13/[tex]\sqrt{2}[/tex], which might be how the question wants it formatted.
Good luck!
Is the following relation a function? {(1, 2), (4, -3), (4, 7), (8, -6)}
a. Yes
b. No
help plsss
Answer:
A function will not have any repeating x values...it can have repeating y values, just not the x ones. So all ur x's have to be different.
This relation is NOT a function because u have repeating x values...u have 2 x values that are 0.3
If 3 centimeters is equal to 30 millimeters, how many centimeters are in 140 millimeters?
Answer:
14
Step-by-step explanation:
divide by 10
Answer:
14
Step-by-step explanation:
You have the proportion:
3 cm: 30 millimeters
divide both sides by 3
1 cm: 10 millimeters
Then, multiply both sides by 14
14cm: 140 millimeters
So 14 centimeters are in 140 millimeters

Group of answer choices
Approximately 0.3 grams of potassium chloride can dissolve in nearly frozen water.
The maximum amount of potassium chloride that can dissolve in water at all temperatures is 0.3 grams.
The amount of potassium chloride that can dissolve in water increases by 1 gram for an increase of 0.3 degrees Celsius in temperature.
The amount of potassium chloride that can dissolve in water increases by 0.3 grams for every 1 degree Celsius increase in temperature.
Answer:

Jane is making wind seashells. She need 12 sea shells for the big one and 8 for the small one. How many wind chimes of the same number would she make form 100 sea shells?
Answer: See explanation
Step-by-step explanation:
Let the wind chimes of the same number that would make her form 100 sea shells be represented by x.
From the information given in the question, this can be denoted as:
12x + 8x = 100
20x = 100
x = 100/20
x = 5
She'll need 5 wind chimes. Let's check
12x + 8x
12(5) + 8(5)
60 + 40 = 100

The expression for the given rectangle with width x and area y is[tex]y = -x^{2} +32[/tex]
it is given that
area of the rectangle = y
width of the rectangle = x
so the length of the rectangle will be = area/width = [tex]\frac{y}{x}[/tex]
perimeter = 64
What is the perimeter of a rectangle?Perimeter is the sum of all four sides of the rectangle.
we can say that,
2(length + breadth) = 64
[tex]2( \frac{y}{x} + x)=64\\\\[/tex]
[tex]\frac{y}{x} + x= 32[/tex]
[tex]\frac{y + x^{2} }{x} = 32[/tex]
[tex]y+x^{2} = 32x[/tex]
[tex]y = -x^{2} +32[/tex]
therefore, the expression for the area of the rectangle,
[tex]y = -x^{2} +32[/tex]
