In triangle ABC, what is the length of side b if B = 48°, C = 81°, and c = 25?
Gekata [30.6K]
The angles should add up to 180. 48 + 81 = 129
180 - 129 = 51

2 sides need to be equal. 25 + 25 = 50

Now solve for b.

A ball is thrown vertically upward. After seconds, its height (in feet) is given by the function 56t - 16t^2 . What is the maxim
mr Goodwill [35]

Answer:

Therefore the maximum height that the reach is 49 feet after 1.75 seconds.

Step-by-step explanation:

Given that,

A ball is thrown vertically upward. After t seconds its height is given by the function

h=56t-16 t^2

where h is height in feet.

Maximum value:

Given function f(x)= at²+bt+c.

  1. Find the value -\frac{b}{2a}
  2. Putting x= -\frac{b}{2a} in the given function.
  3. The maximum value of the given function is f(-\frac{b}{2a}).

Here a= -16 ,  b=56 and c=0

The ball attains its maximum height when t=-\frac{56}{2.(-16)}=1.75 s.

Putting the value of t in the given function

h=(56\times 1.75)-16(1.75)^2

  =49 feet

Therefore the maximum height that the reach is 49 feet after 1.75 seconds.

A company sells a chair for $450. It costs them $350 to make each chair, plus fixed costs for operation of $20,000
lianna [129]

The cost and revenue function of the company are as follows;

  • cost function = 350x + 20000
  • revenue function = 100x - 20000

<h3>How to find the cost and revenue function?</h3>

It costs them $350 to make each chair, plus fixed costs for operation of $20,000. Therefore,

let

x = number of chair

cost function = 350x + 20000

The company sells a chair for $450. Therefore,

revenue function = 450x  - (350x + 20000)

revenue function = 450x - 350x - 20000

revenue function = 100x - 20000
