A car travels 3 times around a traffic circle whose radius is 80 feet. What is the distance the car will travel? Use 3.14 for π

Harman [31]

Answer : Distance will be 1507.2 feet .

Explanation :

Since we have given that

Radius of circle = 80 feet

So,

Circumference of circle is given by

$2\pi r=2\times 3.14\times 80=502.4 \text{ feet}$

Since , a car travels 3 times around a traffic circle.

So,

$\text{ Distance covered by the car will travel}= 3\times 502.4= 1507.2 \text{ feet }$

So, Distance will be 1507.2 feet .

The owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway. If s

navik [9.2K]

Answer:

Step-by-step explanation:

Given that the owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway.

Fencing is used for 2times length and 1 width if highway side is taken as width

So we have 2l+w = 2900

Or w = 2900-2l

Area of the rectangular region = lw

$A(l) = l(2900-2l) = 2900l-2l^2\\$

Use derivative test to find the maximum

$A'(l) = 2900-4l\\A"(l) = -4$

So maximum when I derivative =0

i.e when $l =\frac{2900}{4} =725$

Largest area = A(725)

= $725(2900-2*725)\\= 1051250$

1051250 sqm is area maximum

Point K is located at (7,4) in the coordinate plane. Its image is created by the following rule:

Fynjy0 [20]

We are given coordinate of K point (7,4).

We need to find the new coordinate of K' point.

Given rule is K' = Ro 270°^(k).

That represents rotation of k 270 degree about the origin.

<em>The rule for rotation of 270 degree about the origin is as following:</em>

<em>(x, y) --------> (y, -x).</em>

Now, applying same rule on point (7,4).

(7,4) -----------> (4,-7).

<h3>Therefore, the coordinates of k' is (4,-7).</h3><h3>Correct option is A. (4,-7).</h3>
