Use a proportion to find the missing side length in the following similar figures. Please help me understand and figure out how to solve this question. Thank You! :)
Answers
Answer:
x = 4.5 m ⇒ A
Step-by-step explanation:
The sides of similar triangles are proportion, that means the ratio between the corresponding sides are equal
In the given figure
∵ The two triangles are similar
∵ 2 m and x are corresponding sides
∵ 4 m and 9 m are corresponding sides
∴ [tex]\frac{2}{x}[/tex] = [tex]\frac{4}{9}[/tex]
→ By using cross multiplication
∴ x × 4 = 2 × 9
∴ 4x = 18
→ Divide both sides by 4 to find x
∵ [tex]\frac{4x}{4}[/tex] = [tex]\frac{18}{4}[/tex]
∴ x = 4.5 m

4.5m they are correct

Write the equation of a line that is
parallel to y = 0.5x + 6 and
passes through the point (6, -2).
Answers
Answer:
[tex]y=0.5x-5[/tex]
Step-by-step explanation:
Since the equation is parallel, this means that the slope remains the same which is 0.5.
The remaining thing to do is to find b or y-intercept. To do that, the point (6,-2) and the slope of 0.5 will be used.
[tex]-2=0.5(6)+b[/tex]
When solving for b, it will equal to -5.
Therefore the new equation that is parallel is [tex]y=0.5x-5[/tex]
The equation of a line parallel to y = 0.5x + 6 and passes through the point (6, -2) is y = 0.5x + 1.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know lines parallel to each other have the same slope.
The given line can be written as y = 0.5x + 6.
Therefore, The required line also has a slope of 0.5 passing through the point (6, -2).
- 2 = 0.5×6 + b.
- 2 = - 3 + b.
b = 1.
So, y = 0.5x + 1.

Step-by-step explanation:
What is the difference of outputs for any two inputs that are one value apart?
If you look at the column of "x" [input], you will see that they are 1 unit apart. You can thus look at the corresponding values of "f(x)" [output] and determine their difference. Checking all of those, gives us the difference (same for all).
Output 2 - Output 1:

Alex was put on an improvement at work and they lowers his pay by 3% an hour before his decrease in pay he was making $14 an hour how much money is Alex making an hour afther his decrease in pay
Answers
Answer: Alex is making $ 13.58 after his decrease in pay.
Step-by-step explanation:
Given: Hourly pay for Alex before decrease in pay = $14
His salary decreased by 3%.
New hourly pay = Previous hourly pay - 3% of ( Previous hourly pay )
= $(14-0.03 (14))
= $ (14(1-0.03))
= $ (14(0.97))
=$ 13.58
Hence, Alex is making $ 13.58 after his decrease in pay.

A polynomial function has a degree 4, a negative leading coefficient, and real zeros 3 with multiplicity 2, -2 with a multiplicity of 1, and -3 with a multiplicity of 1
Answers
Answer: p(x) = -n*(x - 3)^2*(x + 2)*(x + 3)
Step-by-step explanation:
For a polynomial whit roots a, b, c, d, e, ... (Where those numbers are not necessarly different)
We can write a polynomial with those roots as:
A*(x -a)*(x - b)*(x - c)*....
Where A is a real number, and it's the leading coefficient (The coefficient that multiplies the highest power term)
In this case we have the roots:
3, 3, -2 and -3 (3 is two times, because it has a multiplicity of 2)
Then this polynomial can be written as:
A*(x - 3)*(x - 3)*(x + 2)*(x + 3)
And we know that the leading coefficient is negative, then we can write:
A = -n, where n > 0.
Then our polynomial is:
p(x) = -n*(x - 3)^2*(x + 2)*(x + 3)
