HELP PLEASE! for p(x)=-2x+5 determine: p(5) p(0) p(-1/2)

Mathematics
1 answer:
Naya [18.7K]3 years ago

Answer:

p(5) =  - 5 \\ p(0) = 5 \\ p( -  \frac{1}{2} ) = 6

Step-by-step explanation:

p(x) =  - 2x + 5

We substitute x = 5,0 and - 1/2 in the equation.

p(5) =  - 2(5) + 5 \\ p(5) =  - 10 + 5 \\ p(5) =  - 5

p(0) =  - 2(0) + 5 \\ p(0) = 0 + 5  \\ p(0) = 5

p( -  \frac{1}{2} ) =  - 2( -  \frac{1}{2} ) + 5 \\ p( -  \frac{1}{2} ) = 1 + 5 \\ p( -  \frac{1}{2} ) = 6

(7b - 2) / (-a + 1)....a = -2, b = 3, c = -1/3
where is he c in this equation ? Because if I just use a and b, my answer is not an answer choice

(7b - 10) / (a - 1)...a = -1, b = 5, c = -2/3
same as before...where is the c in this equation

V = (pi) r^2* h
V = (pi)(5^2)(7)
V = (pi)(25)(7)
V = 175(pi)

How do you cauculate net change ​
Travka [436]

Answer:

You can calculate net change by subtracting the current day's closing price for an asset from the closing price of the previous day!

Step-by-step explanation:

(What net change is) The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.

Answer:

The answer to your question is h = 125.85 ft = 126 ft

Step-by-step explanation:

Process

1.- Determine two equations to solve the problem

    tan 14 = \frac{h}{x}                     (1)

    tan 47 = \frac{h}{x - 386}           (2)

    from (1)                           h = xtan14

    substitute in (2)             tan 47 = \frac{xtan14}{x - 386}

    solve for x                     tan47(x - 386) = xtan14

                                          1.07x - 413.9 = 0.25x

                                          1.07x - 0.25x = 413.9

                                           0.82x = 413.9

                                           x = 413.9/0.82

                                           x = 504.76 ft

2.- Calculate h

                                          h = 504.76 tan 14

                                          h = 125.85 ft = 126 ft
