Answer:

cos²Θ

Step-by-step explanation:

simplify the expression using the identities

tanΘ = [tex]\frac{sin0}{cos0}[/tex]

cos2Θ = 1 - 2sin²Θ

cos²Θ = 1 - sin²Θ

then

tanΘ × sinΘ × cosΘ + cos2Θ

= [tex]\frac{sin0}{cos0}[/tex] × sinΘ × cosΘ + 1 - 2sin²Θ ( cancel cosΘ on numerator/ denominator )

= sinΘ × sinΘ + 1 - 2sin²Θ

= sin²Θ + 1 - 2sin²Θ

= 1 - sin²Θ

= cos²Θ

Answer:

[tex]\cos^2(\theta)[/tex]

Step-by-step explanation:

Trig identities used:

[tex]\cos(2\theta)=\cos^2(\theta)-\sin^2(\theta)[/tex]

[tex]\tan(\theta)=\dfrac{\sin(\theta)}{\cos(\theta)}[/tex]

Therefore,

[tex]\tan(\theta)\times\sin(\theta)\times\cos(\theta)+\cos(2\theta)[/tex]

[tex]=\dfrac{\sin(\theta)}{\cos(\theta)}\times\sin(\theta)\times\cos(\theta)+\cos(2\theta)[/tex]

[tex]=\sin^2(\theta) +\cos(2\theta)[/tex]

[tex]=\sin^2(\theta) +\cos^2(\theta)-\sin^2(\theta)[/tex]

[tex]=\cos^2(\theta)[/tex]

There are 12 dimes and 19 nickels

Since Jace has $2.15 in nickels and dimes.

We know that 1 nickel = $ 0.05 and 1 dime = $0.10

Let

We have that

0.05n + 0.10n' = 2.15   (1)

Since he has 7 more nickels than dimes, we have that

n = n' + 7       (2)

Substituting equation (2) into (1), we have

0.05n + 0.10n' = 2.15   (1)

0.05(n' + 7) + 0.10n' = 2.15  

0.05n' + 0.35 + 0.10n' = 2.15  

0.15n' + 0.35 = 2.15  

0.15n' = 2.15 - 0.35

0.15n' = 1.8

n' = 1.8/0.15

n' = 12

Since the number of nickels, n = n' + 7

Substituting n = 12 into the equation, we have

n = n' + 7

n = 12 + 7

n = 19

So, there are 12 dimes and 19 nickels

Answer:

B (6,0) because when graphed it would make a 90° angle

Answer: (B)

Step-by-step explanation:

For the triangle formed to be a right triangle in this case, the next point has to have the same x value as one of the two points in order for it to form a right triangle.

Hope that helps!

Answer:

B. 3x = 15

Step-by-step explanation:

To find out which equation is the correct one, we just have to replace x with 5 for each one.

2 + x = 3

2 + 5 = 7

Since 2 + 5 is 7, this one is incorrect.

3 x 5 = 15

3 times 5 is 15, so B is correct. Let's try out the other ones anyway.

5 / 2 = 2.5

Incorrect.

5 - 7 = -2

Incorrect.

The only correct equation was B. 3x = 15

The answer is D) AABC is translated 1 unit right, then rotated 90° clockwise about the origin

If you follow the steps translating triangle ABC to A"B"C" and rotating it. You will get that answer. I can envision it mentally simply by following one coordinate at a time which can help me during tests and is how the translations work.

For instance if you moved the A coordinate 2 units to the right it would sit on the y axis, and when rotated 90 degrees wouldn't 1 unit above the x axis but on it. You can simply use mental math for questions like this because they are simple enough to follow where you just pick a coordinate and do the translating and dilating based on what you are given.

Sorry if it's not a mathematical explanation but it's how I usually solve these questions! Hope I could help!!
~Neo

The Sequence of Transformation that has been applied is; D. AABC is translated 1 unit right, then rotated 90° clockwise about the origin.

From triangle translation of ABC to A"B"C" and rotation of it, we can see that;

If we moved the A coordinate 2 units to the right it would sit on the y axis, but when rotated 90°, it would be 1 unit on the x axis.

Thus, applying the principe of translation and rotation we can say that AABC is translated 1 unit right, then rotated 90° clockwise about

the origin.

Answer:

a = 3

b = -7

c = 13

Step-by-step explanation:

[tex]\sf{given \ equation: 3x^2+bx+c[/tex]

[tex]\sf{sum \ of \ roots :\sf\frac{7}{3}[/tex]

[tex]\sf{product \ of \ the \ roots:\frac{13}{3}[/tex]

[tex]\sf{sum \ of \ roots \ = -\dfrac{coefficient \of \ x}{coefficient \ of \ x^2} }[/tex]

[tex]\sf \frac{-b}{3} = \frac{7}{3}[/tex]

[tex]\sf c = \frac{13*3}{3}[/tex]

[tex]\sf c = 13[/tex]

Therefore found that a = 3, b = -7, c = 13

Answer:

Answer:

59.4/ 82.5 = 9/12.5

Step-by-step explanation:

6.6/p = 9/12.15

A fraction equal with another fraction, so we can cross multiply to to have a multiplication equal another multiplication.

6.6 * 12.5  = 9* p

To isolate p (our unknown) we divide both sides by 9

( 6.6 * 12.5) /9   = (9* p)/ 9

( 6.6 * 12.5) /9   = p

82.5 / 9 = p

The proportion is:

6.6/p = 9/12.15, substitute p = 82.5 / 9

6.6/(82.5/9) = 9/12.15, use that: a / (b/c) = (a/1 )*(c/b) = (a*c) / b

(6.6*9)/82.5 = 9/12.5

59.4/ 82.5 = 9 /12.5

[tex]\huge\boxed{\bf\:A = 3W}[/tex]

Step-by-step explanation:

If [tex]\sf\:W = \frac { A } { 3 }[/tex], then A = ?

At first let's shift the the term 'W' to the LHS & A/3 to the RHS to bring the equation in the standard form.

[tex]\sf\:\frac{A}{3}=W[/tex]

Now, we know that, A/3 is the same as ⅓ A. Then,

[tex]\sf\:\frac{1}{3}A=W[/tex]

By multiplting both sides by 3..

[tex]\sf\:\frac{\frac{1}{3}A}{\frac{1}{3}}=\frac{W}{\frac{1}{3}} \\\sf\: A=\frac{W}{\frac{1}{3}}[/tex]

Divide [tex]\sf\:\frac{W}{\frac{1}{3}}[/tex] by its reciprocal.

[tex]\sf\:A=\frac{W}{\frac{1}{3}} \\ \sf\:A = \frac{3W}{1}\\[/tex]

So, the value of A is [tex]\downarrow[/tex]
