now,
The ratio of sides of Triangle SUV is :

In ∆SUV
tan45=VU/SUSo
VU=SU=8 as tan45=1Rest for SV
use Pythagorean theorem
SV²=8²+8²SV=8√2So ratio is

Which of the following functions has a factor of x + 9 ?
A: f (x) = x^3 - 8x^2 - 11x + 18
B: f (x) = x^3 + 10x^2 + 7x - 27
C: f (x) x^3 + 10x^2 + 7x - 18
D: f (x) = x^3 - 8x^2 - 11x + 27
Answers
Answer:
C. f(x) = x³ + 10x² + 7x - 18Step-by-step explanation:
If the function has a factor of x + 9, then the function will have a zero output at x = -9
Lets verify:
A. f(-9) = (-9)³ - 8*(-9)² - 11*(-9) + 18 = -1260, NoB. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 27 = -9, NoC. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 18 = 0, YesD. f(-9) = (-9)³ - 8*(-9)² + 11*(-9) + 27 = -1449, No10. Name the line three ways.

Barry buys a new washing machine.
The value of the washing machine depreciates by 20% each year.
(a)
Barry says 'after 5 years the washing machine will have no value'.
Barry is wrong. Explain why.
Barry wants to work out the value of the machine after 2 years.
(b)
By what single decimal number should Barry multiply the value of the machine when new?
Answers
Answer:
The machine decreases in value by 20% each year.
After 1 year the machine is worth only .8 of its original value.
The machine will only decrease by .2 * (.8 A) in the second year not .2 * A where A is the original amount.
A1 = .8 A
A2 = .8 A1 = .64 A value of machine after 2 years
.8 is the value Barry needs when the machine is new
.8^n never goes to zero
After 10 years value = .8^10 A = .11 A of its original value

how many visits would it take for the two costs to be the same?
(use your expressions and make them equal to each other and solve)
Answers
The 2 expressions: 10x + 100 and 20x + 20
20x + 20:
20 dollars per visit (20x) ; 20 dollar fee (20)
10x + 100 = 20x + 20 Subtract 10x from both sides
100 = 10x + 20 Subtract 20 from each side
80 = 10x Divide by 10

Lourdes plans to jog at least 1.5 miles. Write and solve an inequality to find x, the number of hours that Lourdes will have to jog..
Answers
Answer:
An inequality compares two or more variables by using the <, >, ≤, or ≥ signs.
The number of hours Lourdes will have to jog is 0.4 hours
From the given parameters:
Lourdes plans to jog for at least a distance of 1.5 miles
If Lourdes can jog averagely at the speed of 3.75 mph
Then,
the inequality that can represent the information can be written as:
= 1.5 miles ≤ 3.75 (x) miles/hour
Solving the inequality;
= 1.5 ≤ 3.75 (x)
Making (x) the subject of the formula, we have:
x = 0.4 hours
Therefore, we can conclude that the number of hours lourdes will have to jog is 0.4 hours

Let f(x)=8x−6. What is the value of f(12)?
Answers
Answer:
f(12) = 90
Step-by-step explanation:
This is more of a notation problem than anything else.
The x on the left means that the variable is x. That sounds weird I know, but it starts out this way.
f(variable) = 8*variable - 6
Where you see the word variable, you put the letter x and that gives you the question.
f(x) = 8*x - 6
That is math shorthand for whatever you see on the left, like an x or in this case 12, you put the value 12 in for x on the right. It will look like this.
f(12) = 8*12 - 6 Now it just becomes a calculator problem.
f(12) = 96 - 6
f(12) = 90
