Like the explanation of x and y?
Answer:
You didn't include anything to find X and Y, but I can help you find it in the future.
Step-by-step explanation:
In order to find X or Y in an equation, do the opposite with the last two numbers.
Example:
2x+1 = 5
You see that we are adding here.
So, we must do the opposite with 1 and 5.
1-5=4
That means that 2x will equal four, which means that x must be 2.
2x2+1=5 This is true, because 2x2=4 + 1 = 5.

Step-by-step explanation:
Trigonometry
Inverse trig for this
So we are given adjacent and opposite legs for this part. So tangent is used except because we are finding angle(tan^-1 is used) tan^-1 is not 1/tan
tan^-1(56/47)
We get 49.993744 and so on
So rounded to the nearest degree, that is 50.

Answer:
y= -2/7x-7
Step-by-step explanation:
slope intercept form is just a fancy way of saying y=mx+b
x being your input, y your output, m your slope, and b your y intercept
you can use the slope to determine your equation will look something like: y=-2/7x+b. To find your y-intercept all you do is determine how much the point will increase or decrease so it is equal to (0, y). In this case it will increase by 14 on the x's (so x is equal to 0) and 14*-2/7. When you have determined your y-int and slope you can then plug them into the equation instead of the variables.

Lucia is 5.5 feet tall. She is standing on the roof of a building that is 80 feet tall. She spots a fountain at ground level that she knows to be 122 feet away from the base of the building. What is the measure of the angle of depression formed by Lucia's horizontal line of sight and her line of sight to the fountain? Round your answer to the nearest degree.
Answer:
125°
Step-by-step explanation:
So we know that the total height is 85.5 (building height plus Lucia's height) and that the distance between Lucia and the fountain is 122ft away. As seen in the badly drawn picture below, the question asks us to solve for x, we can do this by first solving for y by using tangent to calculate its value which is the following
tan(y) = opposite / adjacent
tan(y) = 122 / 85.5
tan(y) = 1.4269
y = [tex]tan^{-1}[/tex](1.4269)
y = 54.97
Now that we have the value of y and we know that a straight line has a degree of 180, we can simply subtract the degree of y from 180 to get the degree of x
180 - 54.97 = 125.03
Answer:
about 35°
Step-by-step explanation:
tan^-1(85.5/122)
35.02352736°
=35°

Verona is solving the equation -3 + 4x = 9. In order to isolate the variable term using the addition property of equality, which number should she add to both sides of the equation?
–4
3
–3
4
Answer: 3
Step-by-step explanation:
-3 + 4x = 9
if u add 3 to 9, u get 12. 12 divided by 4 is 3
Add 3 to both sides of the equation to isolate the variable term. Therefore, option B is the correct answer.
The given equation is -3 + 4x = 9.
What is addition property of equality?The addition property of equality tells us that adding the same number to each side of an equation gives us an equivalent equation.
Now, add 3 on both sides.
That is, -3 + 4x +3= 9+3
⇒4x=12
⇒x=3
Therefore, option B is the correct answer.

Rita is playing a game by rolling a rectangular prism made up of cubes. The prism is 6 cubes wide, 3 cubes high, and 4 cubes deep. Rita rolls the cube and says that the top view is a 6-unit by 4-unit rectangle. Which statement explains whether Rita could be correct? Rita could be correct because the cube could land so the 3-cube height and the 4-cube depth make up the top face of the cube. Rita could be correct because the cube could land so the 6-cube width and the 4-cube depth make up the top face of the cube. Rita could not be correct because the top face of the cube is made up of the 6-cube width and the 4-cube depth. Rita could not be correct because the top face of the cube is made up of the 6-cube width and the 3-cube height.
Correctly arranged question is;
Rita is playing a game by rolling a rectangular prism made up of cubes. The prism is 6 cubes wide, 3 cubes high, and 4 cubes deep. Rita rolls the cube and says that the top view is a 6-unit by 4-unit rectangle.
Which statement explains whether Rita could be correct?
A) Rita could be correct because the cube could land so the 3-cube height and the 4-cube depth make up the top face of the cube.
B) Rita could be correct because the cube could land so the 6-cube width and the 4-cube depth make up the top face of the cube.
C) Rita could not be correct because the top face of the cube is made up of the 6-cube width and the 4-cube depth.
D) Rita could not be correct because the top face of the cube is made up of the 6-cube width and the 3-cube height.
Answer:
Option B: Rita could be correct because the cube could land so the 6-cube width and the 4-cube depth make up the top face of the cube.
Step-by-step explanation:
We are told the dimensions of the prism are;
Width = 6 cubes wide
Height = 3 cubes high
Depth = 4 cubes deep.
We are further told that when she rolls that the top view is a 6-unit by 4-unit
For the top view to be 6 unit x 4 unit, it means that the top face is showing the width and depth sides from the dimensions we were earlier given.
Therefore, from the options given, the only one that depicts what I just explained is Option B which says:
The cube could land in such a way that the top face is made up of the 6-cube width and the 4-cube depth

If the perimeter of the parallelogram is 102 feet and the top of the parallelogram measures as 3m and the side measures as m, then what is m? (M does not stand for meters m is a variable.)
Answer:
48 meters.
Step-by-step explanation:
The perimeter of a parallelogram is given by the formula:
[tex]P=2(a+b)[/tex]
Where a is the measure of the length (top), and b is the measure of the slant height (side).
We know that the perimeter is 102.
We also know that the top is 3.
So, let’s substitute 102 for P and 3 for a and solve for b, the side. So:
[tex]102=2(3+b)[/tex]
Divide both sides by 2:
[tex]51=3+b[/tex]
Subtract 3 from both sides:
[tex]b=48\text{ meters}[/tex]
Therefore, the side measures 48 meters.

C. 13,3,2-3
D. 3,4,5
The lengths of the sides that could be for a 45°-45°-90° triangle are 3, 4, 5
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
The lengths of the sides of a 45°-45°-90° triangle have a specific relationship.
In such a triangle, the ratio of the lengths of the sides is 1:1:√2.
√3/2, √3/2, √2
The ratio of the lengths is √3/2 : √3/2 : √2.
This does not match the 1:1:√2 ratio, so it is not a valid option.
3√2, 3√2, 6
The ratio of the lengths is 3√2 : 3√2 : 6.
This does not match the 1:1:√2 ratio, so it is not a valid option.
√3, 3, 2√3
The ratio of the lengths is √3 : 3 : 2√3. This does not match the 1:1:√2 ratio, so it is not a valid option.
3, 4, 5
The ratio of the lengths is 3 : 4 : 5.
This does match the 1:1:√2 ratio, so it is a valid option.
Therefore, the lengths of the sides that could be for a 45°-45°-90° triangle are 3, 4, 5.

There are no results for The impedance Z in an AC (alternating current) circuit is a measure of how much the circuit impedes (hinders) the flow of current through it.The impedance is related to the voltage and the current by the formula V = IZ.If a circuit has a current of (0.4 + 3.0i) amps and an impedance of (0.3 – 2.0i) ohms, find the voltage. Options: A) 0.7+i B) .07+5i C) 0.1+5i D) 6.12+1i
Answer:
Step-by-step explanation:
If the impedance is related to the voltage and the current by the formula V = IZ where;
V is the voltage
I is the current
Z is the impedance
Given
I = 0.4+3i
V = 0.3-2i
Voltage V = (0.4+3i)(0.3-2i)
V = 0.4(0.3)-0.8i+0.9i-6i²
V = 0.12+0.1i -6i²
Since i² = -1
V = 0.12+0.1i-6(-1)
V = 0.12+0.1i+6
V = 6.12+0.1i.
Hence the impedance is 6.12+0.1i
