[tex]\huge \underline\frak \red{Answer}[/tex]
Given thing are
cos Θ = 2/3
we know that Cos Θ = Adjacent Side / Hypotenuse, so we get
Adjacent Side = 2
Hypotenuse = 3
Hypotenuse : BC = 3
Adjacent Side : AB = 2 (Adjacent to ∠ Θ)
Opposite Side : AC = ? (Opposite to ∠ Θ)
To find the Opposite Side - AC , we use Pythagoras theorem ((Hypotenuse)2 = (Leg 1)² + (Leg 2)²)
AC = √ BC² - AB²
AC = √ 32 - 22
AC = √ 9 - 4
AC = √5
Now we will try to simplify square root of 5. As no pairs can be made the final value will be
__
AC = √ 5
So Sin, Cos and Tan will be as follows -
Sin Θ = Opposite Side / Hypotenuse
__
Sin Θ = √5/3
Tan Θ = Opposite Side / Adjacent Side
__
Tan Θ = √5/2
Cos Θ = Adjacent Side / Hypotenuse
Cos Θ = 2/3

Answers
Answer:
Step-by-step explanation:
Let's set up the variables as nickel=n and penny=p, for how many coins he has of each type. What we know is that Calvin had $8.80 total and that he has twice as many nickels as pennies. So, one equation for his total money and another for how many separate coins: 8.80 = 0.01p + 0.05n 2p=n

You have to Mutiply both sides by 8 so it would the look like 3m+4=40. Then you move the 4 over. That would look like 3m=40-4. After subtracting 4 it would look like 3m-36. Divided both sides of equation by 3. So 36 divided by 3 equals 12. M=12
Answer:
m= 12
Step-by-step explanation:
[tex]\frac{3m+4}{8} = 5[/tex]
First multiply both sides by 8 to cancel out the 8 on the left side
[tex]3m + 4 = 80[/tex]
Isolate the m so subtract 4 from both sides.
[tex]3m = 36[/tex]
Divide both sides by 3.

Answers
Answer:
A. x² - 2x - 8
Step-by-step explanation:
At x = -2, 4 graph cut x- axis. So, they are zeroes of f(x).
So, f(x) = k(x+2)(x-4), where k is a constant.
Now, (3, -5) in f(x), we get
-5 = k (3+2)( 3 -4)
-5 = -5k
k= 1
So, f(x) = (x+2)(x-4)
= x² - 2x - 8
So, option A is right.

Yolanda makes $11.25 per hour at her part-time job. During one week, she worked 1225 hours and also earned some tips. Her final pay for the week was $159.50.
How much money did Yolanda earn in tips?
Answers
Answer:
she earned $20 in tips
Step-by-step explanation:
- figure out how much she'll get payed in 12 hours of work, :
12 x $11.25 = $135 for 12 hours work, then find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:
2/5 of $11.25 = $4.50, after all of that, add up both of these sums together to get her total pay for hours worked:
$135 + $4.50 = $139.50
now you need to subtract that sum from her total pay to find out how much money she earned in tips:
$159.50 - $139.50 = $20, so basically thats how i got 20.
Please answer with clear instructions so that i can apply this to other questions.
Answers
Answer:
length = 50 cm
Step-by-step explanation:
let width be w then length = w + 10
area = w(w + 10) = 2000 , that is
w² + 10w = 2000 ( subtract 2000 from both sides )
w² + 10w - 2000 = 0 ← in standard form
Consider the factors of the constant term (- 2000 ) which sum to give the coefficient of the w- term ( + 10)
the factors are + 50 and - 40 , since
50 × - 40 = - 2000 and sum = 50 - 40 = + 10
(w + 50)(w - 40) = 0 ← in factored form
equate each factor to zero and solve for w
w + 50 = 0 ⇒ w = - 50
w - 40 = 0 ⇒ w = 40
Since w > 0 then w = 40 and
length = w + 10 = 40 + 10 = 50 cm
