Steps:
1. calculate the values of y at x=0,1,2. using y=5-x^2
2. calculate the areas of trapezoids (Bottom+Top)/2*height
3. add the areas.

1. 
x=0, y=5-0^2=5
x=1, y=5-1^2=4
x=2, y=5-2^2=1
2. 
Area of trapezoid 1 = (5+4)/2*1=4.5
Area of trapezoid 2 = (4+1)/2*1=2.5

Total area of both trapezoids = (4.5+2.5) = 7

Exact area by integration:
integral of (5-x^2)dx   from 0 to 2
=[5x-x^3/3] from 0 to 2
=[5(2-0)-(2^3-0^3)/3]
=10-8/3
=22/3
=7 1/3, slight greater than the estimation by trapezoids.

Complete these ordered pairs for this equation.<br> (-1, ), (0, ), (1, )2x + y = 3
patriot [66]
Since you're looking for y, I would rewrite as y= first then plug in the x values and solve.
Y = -2x + 3
y = -2(-1)+3
y=5. (-1,5)
Y=-2(0)+3
y=3
(0,3)
y=-2(1)+3
y=-2+3
y=1

Yo dudes I’m need help with this math question #37

Answer:

Percentage of hits in English,French,Spanish and Japanese are 0.59%,0.16%,0.13% and 0.11% respectively.

Step-by-step explanation:

We have to find the percentage of hits for each version of the website.

The hits for the versions are

  • English = 4860
  • French = 1350
  • Spanish = 1080
  • Japanese = 900

<u>Total number of hits = 8190 hits.</u>

Percentage of hits = \frac{number of hits of a  version}{Total number of hits}

Percentage of English = \frac {4860}{8190}

                                     = 0.59 %

Percentage of French = \frac {1350}{8190}

                                     = 0.16 %

Percentage of Spanish = \frac{1080}{8190}

                                      = 0.13 %

Percentage of Japanese = \frac{900}{8190}

                                          = 0.11 %

These are the required percentages.

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test.
Bess [88]

Answer:

4c+6a\leq120\\\\4c+4a\leq100

Step-by-step explanation:

Let c represents child bikes and a represents adult bikes.

Given :  Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test.

With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week.

Then, the required system of inequality :-

4c+6a\leq120----(1)\\\\4c+4a\leq100-----(2)

If company make 10 child bikes and 12 adult bikes in the week.

Then Put c=10 and a=12 bikes in (1) and (2).

4(10)+6(12)=40+72=112\leq120⇒Bike order meets the restrictions

4(10)+4(12)=40+48=88\leq100⇒Bike order meets the restrictions

Hence, the system of inequality best explains whether the company can build 10 child bikes and 12 adult bikes in the week.

4c+6a\leq120\\\\4c+4a\leq100
