4. Here are the equations that define three functions.
luda_lava [24]

The functions f(x), g(x) and h(x) are all linear functions

  • The function value that is largest is h(-100)
  • The function value that is largest is h(-100)
  • The function value that is largest is f(1/100)

<h3>How to determine the function with the largest values</h3>

The functions are given as:

f(x) = 4x - 5

g(x) = 4(x - 5)

h(x) = x/4 -5

At x = 100, we have:

f(100) = 4 * 100 - 5 = 395

g(100) = 4 * (100 - 5) = 380

h(100) = 100/4 - 5 = 20

Hence, the function value that is largest is f(100)

At x = -100, we have:

f(-100) = -4 * 100 - 5 = -405

g(-100) = 4 * (-100 - 5) = -420

h(-100) = -100/4 - 5 = -30

Hence, the function value that is largest is h(-100)

At x = 1/100, we have:

f(1/100) = 4/100 - 5 = -4.96

g(1/100) = 4 * (1/100 - 5) = -19.96

h(1/100) = (1/100)/4 - 5 = -4.9975

Hence, the function value that is largest is f(1/100)

A contractor is considering a sale that promises a profit of ​$35 comma 000 with a probability of 0.7 or a loss​ (due to bad​ we
Nady [450]

Answer:

$19,100

Step-by-step explanation:

The expected profit would be the probability of profit multiplied by the profit and the sum of probability of loss multiiplied by the loss.

So, we can say:

E(p) = P(p)*P + P(L)*L

Where

E(p) is expected profit

P(p) is probabilty of profit (0.7)

P is the profit (35,000)

P(L) is probability of loss (0.3)

L is the loss (-18,000)

Substituting these values, we get:

E(p) = P(p)*P + P(L)*L

E(p) = (0.7)(35,000) + (0.3)(-18,000)

E(p) = 19,100

The expected profit is $19,100

Urgent help needed with right triangle trig!
aliya0001 [1]
Let the unknown side's length be 'b' units .

Then by Pythagorean theorem . We have

{b}^{2}  =  {c}^{2}  -  {a}^{2}
Now substituting the values of a and c in the above equation we get the value of b.

{b}^{2}  =   {24}^{2}  -  {6}^{2}  = 540 \\  \\ b =  \sqrt{540}  = 6 \sqrt{15}
We know that ;

\tan( \theta)  =  \frac{b}{a}  =  \frac{6 \sqrt{15} }{6}  =  \sqrt{15}
