Answer:

8x + 5y > 400

(50, 0) for x-intercept

(0,80) for y-intercept

Step-by-step explanation:

We will let x be the # of tshirts and y be the # of hats.

The inequality is 8x + 5y > 400; the coefficient 8 comes from $8 per tshirt and 5 from $5 per hats.

For x intercept, you let y = 0;

8x + 5(0) = 400;

8x = 400; divide by 8

x = 50 or (50, 0)

For y intercept, you let x = 0;

8(0) + 5y = 400;

5y = 400; divide by 5

y = 80 or (0,80)

Consider a rectangle of length L inches and width W inches. Find a formula for the perimeter of the rectangle. Use upper case le

malfutka [58]

Answer:

a) P=2(L+W)

b) $\frac{dp}{dt}=2\frac{dL}{dt}+2\frac{dW}{dt}$

c)-2 inch/hour

Step-by-step explanation:

given:

length of the rectangle as L inches

width of the rectangle as W inches

a) The perimeter is defined as the measure of the exterior boundaries

therefore, for the rectangle the perimeter 'P' will be

P= length of AB+BC+CD+DA (A,B,C and D are marked on the figure attached)

Now from figure

P= L+W+L+W

=> P=2L+2W .....................(1)

b)now dp/dt can be found as by differentiating the equation (1)

$\frac{dP}{dt}=2(\frac{dL}{dt} )+2(\frac{dW}{dt} )$ .............(2)

c)Now it is given for the part c of the question that

L=40 inches

W=104 inches

dL/dt=2 inches/hour

dW/dt= -3 inches/hour (here the negative sign depicts the decrease in the dimension)

substituting the above values in the equation (2) we get

$\frac{dP}{dt}=2(2)+2(-3)$

$\frac{dP}{dt}=4-6=-2 inches/hour$

The point ( x, the square root of 7/3) in the second quadrant corresponds to angle θ on the unit circle.

Allisa [31]

If (x, 7√3) is a point on the unit circle, then x2 + (7√3)2 = 1 and -1 ≤ x ≤ 1. So, x2 = 1- (7√3)2 = 1- 147 = -146 Since there is no value of x where -1 ≤ x ≤ 1 and x2 = -146, the given point is NOT on the unit circle.
