Answer:

sin(B) =  [tex]\frac{15}{17}[/tex]

cos(B) = [tex]\frac{8}{17}[/tex]

tan(B) = [tex]\frac{15}{8}[/tex]

Step-by-step explanation:

I always find it easiest to model out the triangle: Angle B will be at the converging point of a and c.

Using SOH CAH TOA, we know that the Sin of an angle will be its opposite over hypotenuse. The opposite is 15, and the hypotenuse is 17.

So  [tex]\frac{15}{17}[/tex] is the sin of B.

We also know that the cosine of B will be it's adjacent over hypotenuse. The adjacent is 8 and the hypotenuse is 17, so

[tex]\frac{8}{17}[/tex]

Lastly, we know the tangent of B will be it's opposite over adjacent. The opposite of B is 15, and it's adjacent is 8, so

[tex]\frac{15}{8}[/tex] is the tangent of B.

Answer:

f(3) = 11

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x), that is

f(3) = 3(3) + 2 = 9 + 2 = 11

Answer: f(3) = 11

Step-by-step explanation: Notice that f is a function of x.

So we want to find f(3).

We find f(3) plugging 3 in for x,

everywhere that x appears in the function.

So we have 3(3) + 2 which is 9 + 2 or 11.

So f(3) = 11.

Answer:

Willa can type 60 words per minute

Step-by-step explanation:

60 minutes = 1 hour

1/4 hour = 1/4 × 60 minutes

= 60/4 minutes

= 15 minutes

Quarter of an hour= 15 minutes

Willa can type 900 words in 15 minutes

how many words per minute can willa type?

Words per minute= Total words in 15 minutes / 15 minutes

= 900 / 15

= 60 words per minute

Answer:

Step-by-step explanation:

So we have direct proportions here.

So

715=11

845=x

845*11/715

x=13

To check our work.

715/11=65

65*13=845.

Basically, in this formula, you use cross multiplication. So A*B=B*A. B and B go together and A and A go together/

So we can use the formula x = b*b/a. Since A is one of the A's and the other value of A is missing, we can use this formula to find it.

Answer:

34 minutes

Step-by-step explanation:

Given that T varies inversely as R then the equation relating them is

T = [tex]\frac{k}{R}[/tex] ← k is the constant of variation

To find k use the condition

T = 55 when R = 200, that is

55 = [tex]\frac{k}{200}[/tex] ( multiply both sides by 200 )

11000 = k, thus

T = [tex]\frac{11000}{R}[/tex] ← equation of variation

When R = 325, then

T = [tex]\frac{11000}{325}[/tex] ≈ 34 minutes ( to the nearest minute )

Answer:

Option 2

Step-by-step explanation:

An inverse variation can be represented by the equation xy=k or y=kx .

If (x1,y1) and (x2,y2) are solutions of an inverse variation, then x1y1=k and x2y2=k

Substitute x1y1 for k

x1y1=x2y2   or x1x2=y2y1

The equation x1y1=x2y2 is called the product rule for inverse variations.

Let x be the time required, and y the rate of pumping.

x1 = 55min  y1 = 200gal/min

x2 = Unknown y2 = 325gal/min

(55)(200) = x2(325)

11,000 = x2 (325)

11,000/325 = x2

Answer:

12 - 0 = 12.

Step-by-step explanation:

If you substitute all x values for 0, then you get 12 - 8(0) = 3(0+4). Combine like terms and you will arrive at 12 - 0 = 3(4). Which then goes to 12 - 0 = 12. Since 0 has no value, just remove it from the equation. You are left with 12 = 12.

Answer:

it is x= 0

Step-by-step explanation:

you distribute the numbers in the parentheses first so your new equation would be 12 - 8x = 3x + 12 (basically multiply 3 by what was in the parentheses)

then cancel equal terms so 12 - 8x = 3x + 12 becomes -8x = 3x

after that move the variable and the 3 to the left while changing the sign from + to - (the + sign is implied since it's a positive number) your new equation becomes -8x - 3x = 0

next collect like terms so the numbers with the same variable meaning subtract -8x - 3x also known as -8x + -3x creating the equation -11x =0

finally divide both sides of the equation -11x = 0 by -11 creating x=0

Answer:

Step-by-step explanation:

First we need to find inverse function of f(x) which is written in a form of (f(x))^(-1)

That means that we are actually looking for function f(y) and we need to solve this equation for "y"

y=(4x + 1)/3

3y = 4x + 1

4x = 3y - 1

x = (3y - 1) / 4

f(y) = (3y - 1)/4

Now we simply put the value of 3 instead of y and find the answer:

f(y=3) = (3*3-1)/4 = 2

Step-by-step explanation:

This is a division problem.

1 m = 100 cm

To convert from cm to m we divide the length in cm by 100.

40 m + 50 cm = 40 m + 50/100 m = 40.5 m

The rope is 40.5 m long.

9/4 m = 2.25 m

Each piece is 2.25 m long.
