Answer:
90 degrees
Step-by-step explanation:
......
The answer is A, C, and D.
If you look at the y values column, you'll notice two spots in the chart where there are 0s for the y value.
Since, in those cases, the numbers only exist on the x-axis, there are called x-intercepts.
You'll also notice that the y-values decrease, meaning that the chart goes down from x=-4 to x=0.
Finally, you'll notice an odd sort of pattern, like the values are a mirror of each other, in between 0 and 1. This means there is a line of symmetry at x= 0.5
Step-by-step explanation:
l = length
w = width
l/w = 5/2
l = 5w/2
l×w = 1000ft²
(5w/2)×w = 1000
5w²/2 = 1000
5w² = 2000
w² = 400
w = 20ft
l = 5w/2 = 5×20/2 = 5×10 = 50ft
the length is 50ft.
the width is 20ft.
Assuming that the population follows an exponential function, the it will take the form:
y=a(bˣ)
where:
a=initial value
b=growth factor
x=time
thus plugging our values in the equation we get:
y=40000(1.1ˣ)
thus the population in 2011 when t=3 will be:
y=40000(1.1³)
y=53240
