Answer:

b. x^2+4x

Step-by-step explanation:

So since you don't know the width, you can just represent it as a variable, and in this case that variable will be "x". Now using this variable we can use it to represent the length since there is a relationship between the width and length which is given. Since the length is 4 feet greater than the width, we can represent the length as (x+4). Now to find the area, we simply multiply the length * width, which is x * (x+4) = x^2 + 4x

The length of a rectangular is 7/10 ft .and the width is 1/5ft what is the perimeter
Blababa [14]
<h3>Answer:</h3>

\huge\boxed{1 \frac{4}{5}\ \text{ft}}

<h3>Explanation:</h3>

Change \frac{1}{5} so that is has a common denominator.  \frac{1*2}{5*2}=\frac{2}{10}

Make an equation.  \frac{7+7+2+2}{10}

Add.  \frac{14+4}{10}

Add.  \frac{18}{10}

Divide both sides by 2.  \frac{9}{5}

Convert to a mixed number.  1 \frac{4}{5}

A man starts at a point A and walks 18 feet north. He then turns and walks due east at 18 feet per second. If a searchlight plac
34kurt

Answer:

1/10 per sec

Step-by-step explanation:

When he's walked x feet in the eastward direction, the angle Θ that the search light makes has tangent

tanΘ = x/18

Taking the derivative with respect to time

sec²Θ dΘ/dt = 1/18 dx/dt.

He's walking at a rate of 18 ft/sec, so dx/dt = 18.

After 3seconds,

Speed = distance/time

18ft/sec =distance/3secs

x = 18 ft/sec (3 sec)

= 54ft. At this moment

tanΘ = 54/18

= 3

sec²Θ = 1 + tan²Θ

1 + 3² = 1+9

= 10

So at this moment

10 dΘ/dt = (1/18ft) 18 ft/sec = 1

10dΘ/dt = 1

dΘ/dt = 1/10 per sec
