A huge ice glacier in the Himalayas initially covered an area of 454545 square kilometers. Because of changing weather patterns,

this glacier begins to melt, and the area it covers begins to decrease exponentially.
The relationship between AAA, the area of the glacier in square kilometers, and ttt, the number of years the glacier has been melting, is modeled by the following equation.
A=45e^{-0.05t}A=45e
−0.05t
A, equals, 45, e, start superscript, minus, 0, point, 05, t, end superscript
How many years will it take for the area of the glacier to decrease to 151515 square kilometers?
Give an exact answer expressed as a natural logarithm.

A sports writer wished to see if a football filled with helium travels farther, on average, than a football filled with air. To
Vesnalui [34]

Answer:

(-3.07, 11.07)

Step-by-step explanation:

Given that a sports writer wished to see if a football filled with helium travels farther, on average, than a football filled with air. To test this, the writer used eighteen adult male volunteers. These volunteers were randomly divided into two groups of nine subjects each.

Group   Group One     Group Two  

Mean 300.00 296.00

SD 8.00 6.00

SEM 2.67 2.00

N 9     9    

The mean of Group One minus Group Two equals 4.00

 

standard error of difference = 3.333

   df = 16

t = 1.2000

Margin of error = 3.3333* t critical = 3.3333*2.121

 95% confidence interval of this difference: From -3.07 to 11.07

Malia is planting tomato and pepper plants in her garden each tomato plant t requires 6 square feet and each pepper plant p requ
Misha Larkins [42]

4p + 6t ≤ 150 inequality represents this situation

<h3><u>Solution:</u></h3>

Given that,

tomato plant is represented by "t"

pepper plant is represented by "p"

Malia's garden has an area of 150 square feet

Given that each tomato plant "t" requires 6 square feet of space

<em><u>So, the area required to plant "t" tomato plants</u></em>:

= t x ( Area required by 1 tomato plant)  = t x ( 6 sq ft)  = 6t

Each pepper plant p requires 4 square feet of space

<em><u>So, the area required to plant p pepper plants   </u></em>

= p x ( Area required by 1  pepper plant)   = p x ( 4 sq ft)  = 4p

Given that total area of garden = 150 square feet

area of "p" pepper plants + area of "t" tomato plants = 4p + 6t

<em><u>So, now according to the question: </u></em>

The area occupied by both plants must be less than or equal to total area of garden

Total area of both plants ≤ Total area of the garden

4p + 6t ≤ 150

Thus inequality is found
