if possible, verify sin^2(x)/1 + cos(x) = 1 - cos(x) by rewriting the left hand side of the equation.
I really really don't understand identities, and I'm not getting replies from my teacher. Thank you for any help I do get!!
sin^2(x)/1 + cos(x) = 1 - cos(x)
We know that sin^2 x = 1 - cos^2 x. It is one of our trig identities.
We now have this:
(1 - cos^2 x)/(1 + cos x) = 1 - cos x
Take note:
1 - cos^2 x is a perfect square difference in terms of cosine.
So, (1 - cos^2 x) = (1 + cos x)(1 - cos x).
We now have this:
[(1 + cos x)(1 - cos x)]/(1 + cos x) = 1 - cos x
Do you see what happens on theft side?
On the left side, (1 + cos x) cancels out on the top and bottom.
We are now left with this:
1 - cos x = 1 - cos x
Done!!

Answer:
x = 8 is the answer :)
Step-by-step explanation:
Slope(m) = -2/5
slope is passing through the points: (x,1) and (3,3)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m = \frac{3-1}{3-x}[/tex]
[tex]m=\frac{2}{3-x}[/tex]
[tex]-\frac{2}{5} =\frac{2}{3-x}[/tex]
-2(3 - x) = 2 × 5
-6 + 2x = 10
2x = 10 + 6
2x = 16
x = 8

Answer:
Austing needs 160 boxes to complete the rack.
Step-by-step explanation:
Givens
12 cereral boxes occupies 60 centimeters of shelving.
The rack has 10 meters of shelving, equivalent to 1000 centimeters.
2 meters are already used.
There are 800 centimeters of shelving remaining.
To find the total number of cereal boxes needed to use the whole rack, we just need to use the rule of three: If 12 cereal boxes occupies 60 centimeters of shelving, 800 centimeters would require how many cereal boxes
Therefore, Austing needs 160 boxes to complete the rack.
Answer: C. Y=(1000-200)/5
D. 160 boxes of cereal
Step-by-step explanation: To create the equation I changed the measurements all to centimeters by scaling up the meters by 100 since there are 100 centimeters in a meter.

Trina said that $1.05 + $2.25 = $3.35 because a dollar and 2 quarters plus 2 dollars and a quarter equals 3 dollars and 3 quarters. Do you agree or disagree with her statement? Explain.
Answer:
No, I do not agree
Step-by-step explanation:
Recall :
1 quarter = 25 cents = $0.25
Therefore,
$1 and 2 quarters ; $1 and 2(0.25) =50 cents = $1.50
2 dollars and a quarter ; $2 and 0.25 = $2.25
Adding both:
$1.50 + $2.25
__ $1. 50
__ $2.25
________
__$3.75
_______
The sum is $3.75 and not $3.25
$1 and 2 quarters ; $1 and 2(0.25) =50 cents = $1.50 and not $1.05

Araine borrows $400 on a 4-year loan. She is charged 5% simple interest per year. How much interest is she charged for 4 years? What is the total amount she has to pay back?
Answer:
Interest Charged = $80
Total payback = $480
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Present Value (PV) = $400
Time period (n) = 4 years
Interest rate (r) = 5%
So, we can calculate the future value(FV), by using following formula,
FV = PV ( 1 + n × r)
By putting the value, we get
FV = $400 ( 1 + 4 × 0.05)
= $480
Hence total amount she has to pay back = $480.
Interest charged = FV - PV
= $480 - $400
=$80

Answer:
153, 51, 5.1
Step-by-step explanation:
15.3÷3= 153 tenths÷315.3÷3=51 tenths15.3÷3=5.1Write a recursive sequence that represents the sequence defined by the
following explicit formula:
An = 1 - 5(n − 1)
Answer:
[tex]a_1=1\\a_n=a_{n-1}-5[/tex]
Step-by-step explanation:
a₁ = 1 - 5(1 - 1) = 1 - 5·0 = 1
a₂ = 1 - 5(2 - 1) = 1 - 5·1 = 1 - 5 = a₁ - 5
a₃ = 1 - 5(3 - 1) = 1 - 5·2 = 1 - 5 - 5 = a₂ - 5
a₄ = 1 - 5(4 - 1) = 1 - 5·3 = 1 - 5 - 5 - 5 = a₃ - 5
and so on, therefore:
aₙ = aₙ₋₁ - 5The total weight of the shape blocks on both sides of Michael's pan balance equals 30 grams. Circles weigh 5 grams, squares weigh 10 grams, and triangles weigh 3 grams. The right side has a circle and a square. How many triangles are on the left side?
Answer:
There would be 5 triangles on the other side
Step-by-step explanation:
If the right side has 1 circle and 1 square, that would mean that there is 5g+10g=15g weight on the right side
In total, there is 30g, and we already have 15
We can use the equation 15+3x=30, and by solving, the answer would be 5 triangles.

The Flying Dutchman, located in St. Martin, is the steepest zipline in the world. While sailing downhill at 56 miles per hour, you lose 1,050 feet of elevation across 2,800 feet of cable. If you are at the top getting strapped in, what is the angle of depression between you and a safe landing at the bottom? (Drawing a diagram may help.)
Answer:
Sine angle A = 1,050 / 2,800
Sine angle A = .375
arc sine (.375) = Angle A
Angle A = 22.024 Degrees
