The perimeter of a rectangular building is 346 meters.It is 132 meters long.How wide is it

kakasveta [241]

2L + 2w = 112 ---> L + w = 56 ---> w = 56- L

Area = L*w = L(56-L) = 735

56L - L^2 = 735

0 = L^2 - 56L + 735

0 = (L - 21)(L - 35)

THe dimensions of the rectangle are 35 x 21

There are 15 technicians and 11 chemists working in a research lab. They need to form a 5 person safety committee. In how many w

Burka [1]

<h2>There are a total 65,780 ways in which the committee can be made of 5 members.</h2>

Step-by-step explanation:

Here, the total number of technicians in the lab = 15

The total number of chemists in the lab = 11

So, the total members in the lab = 15 + 11 = 26

So, there are total 26 eligible candidates in the lab from which committee of 5 people has to be made.

Now, since there is <u>no restrictions</u> on the choice, so the committee can be formed in nay way, such that:

It may or may not have any technician.

It may or may not have may chemists.

So, the number of ways 5 member can randomly be chosen from a committee of 26 people = $^{26} C_5$

$^{26} C_5$ = $^{26} C_5 = \frac{26!}{5! \times 21!} = 65,780$

Hence, there are a total 65,780 ways in which the committee can be made of 5 members.

Which equation represents a circle with a center at (2, –8) and a radius of 11?

snow_lady [41]

The equation of a circle is defined by: (x - h)² + (y - k)² = r² where
(h,k) represents the center of your circle and r = the radius

So (x - 2)² + (y + 8)² = 121 is your equation

Biologists have found that the number of chirps some crickets make per minute is related to temperature. The relationship is ver

pychu [463]

Answer:

points (x, y) = {(124, 68), (172, 80)}

y = 1/4x +37

Step-by-step explanation:

For the variable definitions given, the problem statement gives you the points ...

(chirps, temperature) = (x, y) = (124, 68) or (172, 80)

You are asked to find a linear equation that relates x and y.

The slope can be found using the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (80 -68)/(172 -124) = 12/48 = 1/4

The y-intercept can be found from ...

b = y -mx

b = 68 -(1/4)(124) = 37

Then the equation that models the relationship can be written ...

y = 1/4x +37
