1st question:

The formula for area of a triangle given 3 side lengths is A = √(s(s-a)(s-b)(s-c))

where s = (a+b+c)/2

s = (50 + 45 + 25) /2 =  120/2 = 60

Area = √(60(60-50)(60-45)(60-25)

Area = √(60*10*15*35)

Area = √315000

Area = 561.25

Rounded to nearest whole number = 561 square meters.

2nd question:

b. Increasing the number of trapezoids increases the accuracy of the area calculation

c. The area of all the trapezoids can be added together to find the area under the curve.

−5x + y = −3 <br> 3x − 8y = 24
ivann1987 [24]

Answer:

x = 0

y = -3

Step-by-step explanation:

-5x + y = -3 --------------(I)

3x - 8y = 24 ------------(II)

Multiply the equation (I) by 8

(I)*8    - 40x + 8y = -24

(II)     <u>     3x -  8y   =  24</u><u> </u>   {Add and y will be eliminated}

           -37x          = 0

                     x     = 0

Plugin x = 0  in equation(I)

-5*0 + y = -3

     0 + y = -3

           y = -3

PLEASE HELP ME WITH THIS
gladu [14]

Answer:

7

232

Step-by-step explanation:

First

Normally the average of something is total something over total time. I'll do it that way and see what happens.

The total time is ( 4 - 2) = 2 hours.

f(x) = 2^4 - 2 = 14

Change = 14/2 = 7 per hour.

Second

Average = Increase / time.

10000 (1.02)^10 - 10000 * (1.02)^5

10000*1.22 - 10000*1.104

12,200 - 11040

1160

The average per year = 1160 / 5 = 232

LenaWriter [7]

Answer:

Step-by-step explanation:

Given that a common inhabitant of human intestines is the bacterium Escherichia coli.

A cell of this bacterium in a nutrient-broth medium divides into two cells every 20 minutes.

Initial population = 71 cells

Doubles in 1/3 of an hour

P = P_o (2)^{t/3}, where t is the no of hours.

P = 71 (2)^{t/3}

Rate of growth = derivative of P

= 71(2)^{t/3} *(1/3)ln 2\\= \frac{71}{3} (2)^{t/3} ln 2
