Answer:
all work is pictured/shown
Answer:
68cm^2
Step-by-step explanation:
<h2>A trapezium is a type of quadrilateral with the two opposite sides parallel.</h2>
Area of a trapezium= 1/2(sum of parallel sides)×height
Area of the trapezium= 1/2(5+3)×17
Area of the trapezium= 1/2(8)×17
Area of the trapezium=4×17= 68cm^2
A) Determine an equation for the population with respect to the number of years after
2014
, assuming that the population increases at a constant rate.
Solution
The function will be of the form
p
=
a
r
n
, where
a
is the initial population,
r
is the rate of increase,
n
is the time in years and
p
is the population.
p
=
584
,
513
(
1.0002
)
n
b) Using this model, estimate the population of Wyoming in
17
years.
solution
Here,
n
=
17
.
p
=
584
,
513
(
1.002
)
17
p
=
604
,
708
c) Using this model, determine in how many years it will take for the population to exceed
600
,
000
.
Answer:
Width= 85
Length= 485
Step-by-step explanation:
The width will be x, and the length will be x + 400, since it is 400 more than the width.
We know that the perimeter of a rectangle can be found using the equation 2w + 2l.
We plug in the values we have found.
2(x) + 2(x+400) = 1140
4x + 800 = 1140
4x = 340
x = 85
Now we know the width, since it is simply x. To find length all we have to do is add 400.
400 + 85 = 485
10,201 is the answer to the question
