Answer:

sin(X) = 4/5
cos(X) = 3/5
tan(X) = 4/3

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to help you remember the relations between sides and trig functions in a right triangle.

Sin(X) = Opposite/Hypotenuse = 24/30 = 4/5

Cos(X) = Adjacent/Hypotenuse = 18/30 = 3/5

Tan(X) = Opposite/Adjacent = 24/18 = 4/3

_____

You may be expected to leave the trig ratios in the original unreduced form.

Over a 24-hour period, the tide in a harbor can be modeled by one period of a sinusoidal function. The tide measures 4.35 ft at

Answer:

f(x) = 4.35 +3.95·sin(πx/12)

Step-by-step explanation:

For problems of this sort, a sine function is used that is of the form ...

f(x) = A + Bsin(2πx/P)

where A is the average or middle value of the oscillation, B is the one-sided amplitude, P is the period in the same units as x.

It is rare that a tide function has a period (P) of 24 hours, but we'll use that value since the problem statement requires it. The value of A is the middle value of the oscillation, 4.35 ft in this problem. The value of B is the amplitude, given as 8.3 ft -4.35 ft = 3.95 ft. Putting these values into the form gives ...

f(x) = 4.35 + 3.95·sin(2πx/24)

The argument of the sine function can be simplified to πx/12, as in the Answer, above.

Ella and Jake love to skateboard. They created a frame for the ramp and then covered it with wood. How much wood did it take to

Tema [17]

Answer:

144 squared ft

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

Given the information:

height - 3
length - 11
width - 4
slant height - 5

As we know that, the ramp is a triangular Prism, so to find how much wood did it take to cover the ramp we need to find the total surface area of the triangular prism

1/ The area of the central rectangle

A = lw = 11*4 = 44 squared ft

2/ The area of the rectangle to the left

A = hw = 3*4 =12 squared ft

3/ The area of the rectangle to the right

A = slant height* length = 5*11 = 55 squared ft

4/ The area of the two triangles

A = 2 (1/2*h*l) = h*w = 3*11 = 33 squared ft

=> the total surface area of the ramp is: 44 + 12 + 55 + 33 = 144 squared ft

Hope it will find you well.
