A - 1 1/6. If you divide 7 by 6, you get 1 with a remainder of 1/6.

A. 1 1/6
7 divided by 6 6 can go into 1, 1 time so the whole number is 1 and there is 1 left over and the denominator is 6 so the answer is 1 1/6

Let the number of large bookcases be x and number of small bookcases be y, then
Maximise P = 80x + 50y;
subkect to:
6x + 2y ≤ 24
x, y ≥ 2

The corner points are (2, 2), (2, 6), (3.333, 2)
For (2, 2): P = 80(2) + 50(2) = 160 + 100 = 260
For (2, 6): P = 80(2) + 50(6) = 160 + 300 = 460
For (3.333, 2): P = 80(3.333) + 50(2) = 266.67 + 100 = 366.67

Therefore, for maximum profit, he should produce 2 large bookcases and 6 small bookcases.

The path followed by a roller coaster as it climbs up and descends down from a peak can be modeled by a quadratic function, wher

Romashka [77]

Answer:

$y = -0.1x^2 + 250 ft$

Step-by-step explanation:

Because this quadratic equation would have the curve-down form of:

$y = -ax^2 + b$

where a and b are positive coefficient.

If we let the peak (250 ft) of the curve be at x = 0. Then

$y = -a0^2 + b = 250$

$b = 250$

Also at the begins and ends, thats where y = 0, the 2 points are separated by 100 ft. So let the begin at -50 ft and the end at 50ft. We have

$-a(\pm 50)^2 + 250 = 0$

$-a2500 = -250$

$a = 250/2500 = 0.1$

Therefore, the model quadratic equation of our path would be

$y = -0.1x^2 + 250 ft$

What is the rate of change of the volume of the cylinder at that instance (in cubic kilometers per second)?

Kay [80]

Answer:

hello your question is incomplete attached below is the complete question

answer : -2400 π

Step-by-step explanation:

dr/dt = -12 km/s

h = 2.5 km

r = 40 km at some instant

hence the rate of change of Volume of cylinder at that instance

= dv / dt = $d(\pi r^h ) / dt$

= $\pi h\frac{d(r^2)}{dt}$ = $-\pi h *2r *dr/dt$

hence ; dv / dt = -2400 π
