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!!​

Answers

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!!

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]

Answer:

∠ B = 54°

Step-by-step explanation:

Supplementary angles sum to 180°, so

7x + 7 + 4x - 14 = 180

11x - 7 = 180 ( add 7 to both sides )

11x = 187 ( divide both sides by 11 )

x = 17

Then

∠ B = 4x - 14 = 4(17) - 14 = 68 - 14 = 54°

The 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?

Answers

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.

A. 1/12
B. 1/11
C. 7/12
D. 1/2

Answers

There are 4+3+5=12 marbles in the bag.
Let’s find how many green and red balls are in the bag. 4+3=7
So that means the probability of picking a red marble followed by a green marble is 7/12 (C)

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.

Answers

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

Write a recursive sequence that represents the sequence defined by the
following explicit formula:
An = 1 - 5(n − 1)

Answers

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

a = 1 - 5(2 - 1) = 1 - 5·1 = 1 - 5 = a - 5

a = 1 - 5(3 - 1) = 1 - 5·2 = 1 - 5 - 5 = a - 5

a = 1 - 5(4 - 1)  = 1 - 5·3 = 1 - 5 - 5 - 5 = a - 5

and so on, therefore:

                              aₙ = aₙ₋₁ - 5
