Answer:

48x² + 24x + 3

Step-by-step explanation:

Width = (4x + 1) in

Length = 3 *width = 3*(4x + 1) = 3*4x + 3*1

= (12x + 3) in

Area of rectangle = length * width

= (12x + 3) (4x + 1)

= 12x *4x + 12x *1 + 3*4x + 3*1

= 48x² + 12x + 12x + 3

= 48x² + 24x + 3

From the top of a vertical tower, 331 feet above the surface of the earth, the angle of depression to a doghouse is 28 degrees 8

Elena L [17]

Answer:

619.13 feet

Step-by-step explanation:

Please find the attachment.

Let x represent the distance between doghouse to the foot of the tower.

We have been given that from the top of a vertical tower, 331 feet above the surface of the earth, the angle of depression to a doghouse is 28 degrees 8'. We are asked to find the distance between doghouse to the foot of the tower.

First of all, we will convert our given angle into degrees as it is given in degrees and minutes.

We will divide 8 by 60 to convert 8 minutes into degrees as:

$\frac{8}{60}=0.13333$

The doghouse, tower and angle of depression forms a right triangle with respect to ground, where, 331 feet is opposite side and x is adjacent side to angle 28.13 degrees.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$

$\text{tan}(28.13^{\circ})=\frac{331}{x}$

$x=\frac{331}{\text{tan}(28.13^{\circ})}$

$x=\frac{331}{0.534623339864}$

$x=619.12747783$

Upon rounding to nearest hundredth, we will get:

$x\approx 619.13$

Therefore, the doghouse is 619.13 feet far from the foot of the tower.

An organization will give a prize to a local artist. The artist will be randomly chosen from among 10 painters, 3 sculptors, and

Fofino [41]

The probability is 8/18 or 44%.

Since there are 3 sculptors and 5 photographers, and the question is asking for either a sculptor or photographer, you add them together. There are a total of 18 artists, and the probability is the chance of a certain thing happening over the total amount of things that can happen (i.e. a coin landing on heads is 50%).

The answer would be 8/18.
