Answer:

b. $\frac{1}{16}$

Step-by-step explanation:

A = {2, 3}

B = {4, 6}

C = set of all possible fractions where, the numerators are in set A and the denominators are found in Set B

The 4 possible fractions we can get for set C are as follows:

Set C: { $\frac{2}{4}$ , $\frac{2}{6}$ , $\frac{3}{4}$ , $\frac{3}{6}$ }

Multiply all to get the product of all elements in Set C:

$\frac{2}{4}*\frac{2}{6}*\frac{3}{4}*\frac{3}{6}$

Simplify where necessary

$\frac{1}{2}*\frac{1}{3}*\frac{3}{4}*\frac{1}{2}$

$\frac{1*1*3*1}{2*3*4*2}$

$\frac{3}{48}$

Simply further

$\frac{1}{16}$

On a morning of a day when the sun will pass directly overhead, the shadow of a 60-ft building on level ground is 25 ft long.

AysviL [449]

Answer:

The shadow is decreasing at the rate of 3.55 inch/min

Step-by-step explanation:

The height of the building = 60ft

The shadow of the building on the level ground is 25ft long

Ѳ is increasing at the rate of 0.24°/min

Using SOHCAHTOA,

Tan Ѳ = opposite/ adjacent

= height of the building / length of the shadow

Tan Ѳ = h/x

X= h/tan Ѳ

Recall that tan Ѳ = sin Ѳ/cos Ѳ

X= h/x (sin Ѳ/cos Ѳ)

Differentiate with respect to t

dx/dt = (-h/sin²Ѳ)dѲ/dt

When x= 25ft

tanѲ = h/x

= 60/25

Ѳ= tan^-1(60/25)

= 67.38°

dѲ/dt= 0.24°/min

Convert the height in ft to inches

1 ft = 12 inches

Therefore, 60ft = 60*12

= 720 inches

Convert degree/min to radian/min

1°= 0.0175radian

Therefore, 0.24° = 0.24 * 0.0175

= 0.0042 radian/min

Recall that

dx/dt = (-h/sin²Ѳ)dѲ/dt

= (-720/sin²(67.38))*0.0042

= (-720/0.8521)*0.0042

-3.55 inch/min

Therefore, the rate at which the length of the shadow of the building decreases is 3.55 inches/min

Which equation can be used to calculate the area of the shaded triangle in the figure below?

GrogVix [38]

Answer:

It is $\frac{1}{2}$ (12 × 4) = 24

Step-by-step explanation:

$\frac{1}{2}$ (base × height) = area of triangle

$\frac{1}{2}$ (12 × 4) = area

area = 24
