Use a trigonometric ratio to find the value of x. Round your answer to the nearest tenth
Answers
Answer:
x ≈ 8.1 units
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan72° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{25}{x}[/tex] ( multiply both sides by x )
x × tan72° = 25 ( divide both sides by tan72° )
x = [tex]\frac{25}{tan72}[/tex] ≈ 8.1 ( to the nearest tenth )

What will happen to a number, if it was added to its inverse?
Answers
Answer:
The word "inverse" in the question is ambiguous, since x usually has inverses under both addition and multiplication. ... If the question is asking about the additive inverse (opposite), then the sum is always 0 for any x . So the sum takes its maximum value for any x .
Step-by-step explanation:
Answer:
Zero
Step-by-step explananation:
An inverse is the opposite of another number, so if you add them together it would equal zero.
Here are a few examples.
5+-5=0
9+-9=0
150+-150=0
-220+220=0
-476+476=0
The inverse is simply the originall number, but on the opposite side of the number line. Meaning you add or take away the negative sign, depending on the original number.

Answer:
x = 4, -4
Step-by-step explanation:
You can do this by simply pressing the calculator OR by simplify
4x^2 - 64 = 0
(2x)^2 - 8^2 = 0
(2x - 8)(2x + 8) = 0
∴ 2x - 8 = 0 or 2x + 8 = 0
x = 4 or x = -4
Line H is represented by the following equation: 2x + 2y = 8
What is most likely the equation for line K so the set of equations has infinitely many solutions?
x + 2y = 2
x + y = 4
2x + y = 6
x − y = 8
Answers
Answer:
B
Step-by-step explanation:
Line H is represented by the equation:
[tex]2x+2y=8[/tex]
And we want to find Line K such that the set of equations has infinitely many solutions.
Remember the three solution sets for linear equations:
If the two are parallel, they have no solutions. If the two are not parallel, they will intersect and thus have only one solution. If the two are the exact same line, then they will have infinitely many solutions.From Line H, we can divide both sides by two. This yields the equivalent equation:
[tex]x+y=4[/tex]
Therefore, the new equation and Line H are the same line. Thus, they will have infinitely many solutions.

Answers
Answer:
The answer is below
Step-by-step explanation:
Write the coordinates of the vertices after a dilation with a scale factor of 1/5 , centered at the origin.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
Dilation is the reduction or enlargement in the size of an object by a scale factor (k). If k > 1, it is an enlargement and if k < 1, it is a reduction. If a point A(x, y) is dilated by a factor k, the new point is A'(kx, ky).
Therefore, if the vertices are dilated with a scale factor of 1/5 , centered at the origin. The new point is:
S(5, -10) → S′(1 , -2) T(10, -10) → T′(2 , -2) U(5, 10) → U′(1 , 2)

The length of play area A must be 1 foot longer than four times its width. The width of play area B must be 2 feet longer than the width of play
area A, and the length must be 2 feet longer than three times its own width. In
addition, the areas of the two play areas must be equal.
Write a system of equations to represent this situation, where y is the area of the play areas and x is the width of play area A. Which statement
describes the number and viability of the system's solutions?

The graph of linear function g passes through the point (-3,-10) and has a slope of 2.
What is the zero of g.
Answers
Answer:
2
Step-by-step explanation:
when x is 2 y = 0.
lets start with writing the function's equation;
it has a slope of 2 so 2x + k = y
given in the question when x = -3, y = -10
so k = -4
y = 2x - 4, 0 = 2x-4 then x = 2

Daniel is baking a cake for Aaron's birthday. The recipe requires 2 1/2 cups of butter, 1/3 cups of brown sugar, and 1/2 cups of baking powder. What is the total amount of ingredients in cups if Daniel makes the cake twice as large as the recipe calls for?
Answers
Answer
4 6/12 or 2 3/4 cups of total ingredients
Step-by-step explanation:
There are 2 1/2 cups of butter, 1/3 cups of brown sugar, and 1/2 cups of baking powder.
You'd want to make the denominators the same numbers so it would be easier to divide.
So I multiplied 2 1/2 times 3, 1/3 times 2, and 1/2 times 3.
Then all the numbers would have a denominator of 6. Don't multiply the whole numbers or the numerators. Just the denominator.
''THE NUMBERS'' would change to 2 1/6, 1/6, and 1/6.
If I were to add that it would be 2 3/6.
BUT, You need to multiply by 2 after because it says in the question "How many ingredients in cups will Daniel make the cake twice as large".
What is 2 3/6 times 2 = 4 6/12 total.
If it says to simplify the answer. It would be "'2 3/4 total'' or both answers are correct

Answers
Answer:
d1 = 192
d2 = 192
Step-by-step explanation:
step 1
From the imformation given, the distance is the same
so from the table
d1 = 64t
d2 = 48(7-t)
the distance is the same, it means
d1 = d2
therefore we can get the time(t) from here
64t = 48(7-t)
64t = 336 - 48t
collect like terms
64t+48t = 336
112t = 336
t = 336/112
t = 3
substitute t into d1 to get the distance
d1 = 64t
d1 = 64 × 3
d1 = 192
Note, d1 = d2
d2 = 192 too

A shark is swimming 28 feet below sea level. If the angle of depression from a boat on the water is 19 degress. What is the distance between the boat and the shark?
Answers
Answer:
81.3 feet
Step-by-step explanation:
A shark is swimming 28 feet below sea level. If the angle of depression from a boat on the water is 19 degrees What is the distance between the boat and the shark?
We solve the above question using Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = Angle of depression = 19°
Distance between the boat and the shark = Adjacent = ? = x
Opposite = 28 feet
Hence:
tan 19 = 28/x
Cross Multiply
tan 19 × x = 28
x = 28/tan 19
x = 81.317904575 feet
Approximately = 81.3 feet
The distance between the boat and the shark is 81.3 feet
