What does AC=?<br> Round your answer to the nearest hundredth. <br><br> Please help
faltersainse [42]

Answer: About 3.06

Step-by-step explanation:

  We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.

  Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.

      cos(θ) = \frac{adjacent}{hypotenuse }

      cos(40) = \frac{x}{4}

      0.766 ≈ \frac{x}{4}

      3.06 ≈ x

      x ≈ 3.06

A parachutist descends 44 feet in 4 seconds. Express the rate of the parachutist's change in height as a unit rate.
Montano1993 [528]

The unit rate of the parachutist change in height is 11 feet per second.

   • In Mathematics, Unitary method is a technique for solving a question by first finding the value of a single unit and then finding the required value by multiplying the number by value of single unit .

   • We use unitary method to find the ratio of one thing with respect to other thing.

   • There are two types of unitary method one is Direct Variation and the other is Inverse variation.

We have the rate of descend as 44 feet in 4 sec.

So, in 1 second it will be = 44 / 4 = 11 feet.

Which is the unit rate.

Therefore, the unit rate of descend for the parachutist is 11 feet per second.

Step-by-step explanation:

(f-g)(x) just means f(x)-g(x).

So

-3x-5-(4x-2)\\-3x-5-4x+2\\-7x-3
