PQ¯¯¯¯¯ and PR¯¯¯¯¯ are tangent to ⊙ S. Identify PQ.
pls help 30 points
Answer:
9
Step-by-step explanation:
Because line PQ and line PR are both tangent to circle S, it would result in them being equal. So first to find PQ, you would have to find the value of variable x. To do this you would set both equations equal to each other and solve
6x - 9 = 2x + 3
-2x -2x
4x - 9 = 3
+9 +9
4x = 12
x = 3
Now you have to substitute 3 back into the equation for PQ:
6(3) - 9
18 - 9
= 9
Resulting in PQ = 9, to check your answer, take the value of x (3) and substitute it into PR and you should also get 9
2(3) + 3
6 + 3
= 9
10. The cost of manufacturing a kitchen cabinet consists of the cost of materials at $250, labour cost at $120 and warehousing cost at $60. After a change of management, the cost of materials and labour cost are increased by 10% and 8% respectively, and warehousing cost is decreased by 18%. Calculate the percentage change in the cost of manufacturing the kitchen cabinet. State whether it is an increase or a decrease.
Using proportions, the percentage change in the cost of manufacturing the kitchen cabinet was a increase of 5.5%.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The standard cost is given as follows:
S = 250 + 120 + 60 = $430.
After the increases, the price will be given as follows:
S = 250 x 1.1 + 120 x 1.08 + 60 x 0.82 = $453.8.
The price increased. The percent change, given by the change divided by the initial value, is:
P = 23.8/430 x 100% = 5.5%.

The length of a picture is 10.5cm and the diagonal is 18.2cm . What width must have to meet a right angle ?
The width that must meet a right angle is 14.87 cm
How to determine the width?The given parameters are:
Length = 10.5 cmDiagonal = 18.2 cmThe width is calculated using the following Pythagoras theorem.
Width^2 = Diagonal^2 - Length^2
So, we have:
Width^2 = 18.2^2 - 10.5^2
Evaluate
Width^2 = 220.99
Take the square root of both sides
Width = 14.87

What is depreciation?Depreciation is the practice of subtracting a business asset's cost over a number of years as opposed to just one.
Depreciation is used to adjust the cost of a productive asset with a longer-than-year-long useful life to the income generated by operating the asset. The expense of the asset is typically dispersed across the years that it is utilized.
Calculation for the asset value after depreciation of 20% every year.
The purchasing cost of washing machine is $300.
The rate after 6 years is-
Rate = purchased price×[tex](1-r)^{t}[/tex]

Answer:
Please review the equation format. I made an assumption (below) for this answer.
-0.57
Step-by-step explanation:
5x2 45x 24 = 0 is not a quadratic formula,
5x^2 + 45x + 24 = 0 is, however. Also, it gives -.8.43 as one solution. The other is −0.569351, or -0.57 to the nearest hundredth.
The other solution of the given quadratic equation would be -0.57
Quadratic Equation
An algebraic equation of the second degree in x is known as a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.
The given quadratic equation is,
5x² + 45x + 24 = 0
Here,
a = 5
b = 45
c = 24
Applying the Quadratic Formula
The quadratic formula for the two roots of a quadratic equation is given as,
[tex]x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] ........... (1)
and [tex]x=\frac{-b+\sqrt{b^{2}+4ac } }{2a}[/tex] ............ (2)
Substituting the values of a, b, and c in equation (1), we get,
x = -8.43
Calculating the Second Root

[tex]x=\frac{-45+\sqrt{45^{2}+4(5)(24) } }{2(5)}[/tex]

The quadratic $x^2 1300x 1300$ can be written in the form $(x b)^2 c$, where $b$ and $c$ are constants. What is $\frac{c}{b}$
The value of c/b when the quadratic equation x² + 1300x + 1300 is written in the form (x + b)² + c, b and c being constants is -648.
The given quadratic expression needs to be expressed using the perfect square method to be of the form (x + b)² + c.
We express the quadratic expression x² + 1300x + 1300 using the perfect square method following these steps:
x² + 1300x + 1300
= x² + 2x(1300/2) + (1300/2)² + 1300 - (1300/2)²
= x² + 2x(650) + (650)² + 1300 - (650)²
= (x + 650)² + 1300 - 422500
= (x + 650)² - 421200.
Comparing this to (x + b)² + c, we get:
b = 650, and c = -421200.
Therefore, the value of c/b = (-421200)/650 = -648.
Therefore, the value of c/b when the quadratic equation x² + 1300x + 1300 is written in the form (x + b)² + c, b and c being constants is -648.
The question seems improper. The proper question is:

Inverse Variation is when y decreases as x increases although it's not linear and the x and y has a constant product.
By observing the table, you'll see as x increases, y decreases. You'll also notice a constant product of 20 between x and y. (2 * 10) = 20. (4 * 5) = 20. ( (8 / 1) * (5 / 2) = 40/2 = 20))... and so on. So the function can be represented as xy = 20

-6x+4y=-8
6x-12y=14
.-16y=6
.-8y=6
.-8y=-22
.-16y=-22
Answer:
x=5/6 but since you gave options in terms of y: -8y=6
Step-by-step explanation:
When you add equations together to solve for a systems of equations, it because you want to cancel out one of the values, and in this case it's the 6x, since the 6x + (-6x) = 0
Now all you need to do is add the -12 and 4y and you get -8y which is going to be the left side of the equation
Now add the -8 and 14 and you get 6 which is going to be the right side of the equation. This gives you the equation:
-8y = 6
Divide both sides by -8
y = -0.75
Now plug this into either original equation but in this case I'll just use the -6x+4y=-8
Plug in -0.75 as y
-6x+4(-0.75) = -8
-6x-3=-8
-6x=-5
Divide both sides by -6
x=5/6
