Answer:

f(3) = 23

Step-by-step explanation:

To evaluate f(3) substitute x = 3 into the expression

f(3) = 2(3)² + 5 $\sqrt{3-2}$

= (2 × 9) + (5 × $\sqrt{1}$ )

= 18 + (5 × 1) = 18 + 5 = 23

The profit per acre from a grove of orange trees is given by x(190 − x) dollars, where x is the number of orange trees per acre.

nasty-shy [4]

Answer:

$P(x) = 190 x -x^2$

In order to maximize the last equation we can derivate the function in term of x and we got:

$\frac{dP}{dx} = 190 -2x$

And setting this derivate equal to 0 we got:

$\frac{dP}{dx} = 190 -2x=0$

And solving for x we got:

$x = 95$

And for this case the value that maximize the profit would be x =95 and the corresponding profit would be:

$P(x=95)= 95(190-95)= 95*95 = 9025$

Step-by-step explanation:

For this case we have the following function for the profit:

$P(x) = x(190-x)$

And we can rewrite this expression like this:

$P(x) = 190 x -x^2$

In order to maximize the last equation we can derivate the function in term of x and we got:

$\frac{dP}{dx} = 190 -2x$

And setting this derivate equal to 0 we got:

$\frac{dP}{dx} = 190 -2x=0$

And solving for x we got:

$x = 95$

And for this case the value that maximize the profit would be x =95 and the corresponding profit would be:

$P(x=95)= 95(190-95)= 95*95 = 9025$

Right and solve a proportion to answer the question 3/4 is 75% of what number

ra1l [238]

Answer: 1

Step-by-step explanation:

Let the number be p

75% of P= 3/4

75/100 of P = 3/4

0.75P =3/4

Cross multiply

0.75p×4=3

0.3p=3

P=3/0.3

P= 1

Therefore 75% of 1 = 3/4

If the output number y is -52 (y=5x-2) what is the input number? SHOW WORK

nordsb [41]

Answer:

the input number is -10

Step-by-step explanation:

output is always y

input is always x

so instead of y, put -52

-52=5x-2 add 2 to each side to ger 5x by itself

-50=5x divide both sides by 5 to get x by itself

-10=x

x is the input so the input is -10
