Answer:

(A)

Step-by-step explanation:

Given: sin ___ = 7/12

To find: The missing angle of sine.

Solution: Let the missing angle be A, then the given equation can be written as:

sinA=\frac{7}{12}

Taking sin inverse on both sides, get

A=sin^{-1}\frac{7}{12}

A=sin^{-1}(0.583)

A=35.69^{\circ}

Therefore, value of the missing angle is 35.69^{\circ}, thus option A is correct.

Sin x = 7/12
x = arcsin (7/12) = 35.69°

Which of the following functions is quadratic? f(x)=3(x-4)(x+3), f(x)=5^2, f(x)=2/x, f(x)=2x^3+3x^2-5
DENIUS [597]
In B 5^2 = 25. There is no x anywhere.
In C f(x) = 2/x is a function of a reciprocal, not a quadratic.
In D f(x) = 2x^3 + 3x^2 - 5 is a cubic. A cubic is not a quadratic. The highest power of a quadratic is x^2

That leaves A. When you expand the brackets, you get
3(x^2 + 3x- 4x - 12)
2(x^2 - x - 12) when you remove the brackets you get
2x^2 - 2x - 24. The highest power of x is x^2. This is your quadratic.

Dmitriy789 [7]

Answer:

15

Step-by-step explanation:

3 stars = 18

1 star = 6

14-6=8/2 = 4

1 heart = 4

1 spade = -1

4 + -1=  3

3 + (2 stars)

3 + 12 = 15

Write the product as a sum: 14cos(39x)sin(19x)
charle [14.2K]

Recall that

sin(<em>a</em> + <em>b</em>) = sin(<em>a</em>) cos(<em>b</em>) + cos(<em>a</em>) sin(<em>b</em>)

sin(<em>a</em> - <em>b</em>) = sin(<em>a</em>) cos(<em>b</em>) - cos(<em>a</em>) sin(<em>b</em>)

Adding these together gives

sin(<em>a</em> + <em>b</em>) + sin(<em>a</em> - <em>b</em>) = 2 sin(<em>a</em>) cos(<em>b</em>)

To get 14 cos(39<em>x</em>) sin(19<em>x</em>) on the right side, multiply both sides by 7 and replace <em>a</em> = 19<em>x</em> and <em>b</em> = 39<em>x</em> :

7 (sin(19<em>x</em> + 39<em>x</em>) + sin(19<em>x</em> - 39<em>x</em>)) = 14 cos(39<em>x</em>) sin(19<em>x</em>)

7 (sin(58<em>x</em>) + sin(-20<em>x</em>)) = 14 cos(39<em>x</em>) sin(19<em>x</em>)

7 (sin(58<em>x</em>) - sin(20<em>x</em>)) = 14 cos(39<em>x</em>) sin(19<em>x</em>)

I never really understood what this was could u help
ycow [4]

Answer:

1. f(4) or f(n)= 28

2. f(-2) or f(n)= -2

(please consider marking brainliest <3 )

Step-by-step explanation:

n=4                           n=-2

f(n)= 5(n)+8              f(n)= 5(n)+8

f(n)= 5(4)+8              f(n)= 5(-2)+8

(n)= 20+8                 f(n)= -10+8

f(n)=28                      f(n)=-2
