Find all solutions of each equation on the interval [0, 2pi)
(cos^3x)/(sinx )=cot x
Answer:
Step-by-step explanation:
(cos³x)/(sin x)=cot x
(cos³ x)/(sin x)=(cos x)/sin x
sin x≠0
x≠0,π,2π
cos³x-cos x=0
cos x(cos²x-1)=0
either cos x=0,x=π/2 ,3π/2
or
cos²x-1=0
2 cos²x=2
1+cos 2x=2
cos 2x=1=cos2nπ,n=0,1,2
2x=2nπ
x=nπ
x=0,π,2π
But x≠0,π,2π
so x=π/2,3π/2

Every year Ethan earns 38,428. Each year he spends 21,728 on expenses. How much money should he have left over?
Answer:
16,700
Step-by-step explanation:
Given that,
Earning of Ethan = 38,428
Ethan spends 21,728 on expenses.
We need to find the amount of money he has left over. It can be calculated as follows :
Left money = Earning - Spent
= 38,428 - 21,728
= 16,700
So, he has left over 16,700.
Identify the sum of the interior angle measures of a convex octagon.
O 1080°
O 1260°
O 1620°
O 1440°
The sum of the interior angle measures of a convex octagon is 1080. the correct option is A.
What is an octagon?An octagon is an 8-gon, or polygon with eight sides, in geometry. The Schläfli symbol for a regular octagon is 8, and it can also be built as a nearly regular truncated square.
The interior angle will be calculated as,
Angle = (n - 2) x 180
Angle = ( 8 - 2 ) x 180
Angle = 1080
Therefore, the sum of the interior angle measures of a convex octagon is 1080. the correct option is A.

The price of a stock is $40.25 and it is increasing by 5.4%. What will be the price in 10 years?
Answer:
$68.10
Step-by-step explanation:
Your wording is confusing, btu I assume that you mean the stock increases by 5.4% each year. If that’s the case, you have to use the equation 40.25(0.054+1)^10. 40.25 represents your starting value. 0.054 represents the value change in decimal form and the +1 is because your stock is increasing, which means you need to add 1 so it actually increases. the power of 10 is the 10 year period of your stock increasing. So, if you simplify that, you get 68.10 (Remember, you have to round your answer to the nearest hundredth because it is cents). And, you should get 68.10.
pls help with this problem if u do thx <3
======================================
Work Shown:
c = price of coat before discount
0.33c = discount = amount you save
c - 0.33c = original price minus discount = final price
c - 0.33c = 1c - 0.33c = (1-0.33)c = 0.67c = final price
In short, c - 0.33c = 0.67c
They are two ways of expressing the same thing.
You can think of it like saying 100% - 33% = 67%
If you save 33%, then you still have to pay the remaining 67% of the original cost.
-------------
Example:
Let's say the coat is $100 before the discount
c = 100
0.33*c = 0.33*100 = 33 dollars is how much you save
c - 0.33c = 100 - 33 = 67 dollars is the final price
0.67c = 0.67*100 = 67 matches with the previous figure above

Find the incorrect step in each solution and explain whit it is incorrect.
Answer:
Step-by-step explanation:
Mai:
She subtracted 5x instead of distributing. This is incorrect, because since it is in ( ), it has to be multiplied by 3.
Correct: 3(5x + 9) = 15x + 27
12x + 3 = 15x + 27
Noah:
Added 15x instead of subtracting. This is incorrect, because to combine like terms on each side you would add a negative number and subtract a positive number.
Correct: 12x + 3 = 15x + 27
12x - 15x = 27 - 3
-3x = 24
x = 24 / -3
x = -8

Determine the measure of angle A, B, and C in triangle ABC. If m∠A=(x-10)°,m∠B=(2x-50)°,and m∠C=x°
Answer:
m∠A = 50°
m∠B = 70°
m∠C = 60°
Step-by-step explanation:
Determine the measure of angle A, B, and C in triangle ABC. If m∠A=(x-10)°,m∠B=(2x-50)°,and m∠C=x°
In a Triangle, the sum of the interior angles of a triangle = 180°
Step 1
We solve for x
Hence:
m∠A + m∠B + m∠C= 180°
(x-10)°+ (2x-50)°+ x° = 180°
x - 10 + 2x - 50 + x = 180°
4x - 60 = 180°
4x = 180° + 60°
4x = 240°
x = 240°/4
x = 60°
Step 2
Solving for each measure
x = 60°
m∠A=(x-10)°
= 60° - 10°
= 50°
m∠B=(2x-50)°
= 2(60)° - 50°
= 120° - 50°
= 70°
m∠C=x°
= 60°

Step-by-step explanation:
2(d − 6) − 3 = 1 solve for d
Answer:
d = 8
Step-by-step explanation:
2(d -6) - 3 = 1
+3 +3
2(d-6) = 4
/2 /2
(d-6) = 2
+6 +6
(d) = 8
d = 8
Answer:
d=8
Step-by-step explanation:
2(d-6)-3=1
Add 3 to both sides:
2(d-3)+3=1+3
Simplify:
2(d-6)=4
Divide both sides by 2:
2(d-6)/2=4/2
Simplify:
d-6=2
Add 6 to both sides:
d-6+6=2+6
Simplify:
d=8
