Answer: Option b.
Step-by-step explanation:
First, you need to calculate the ratio of the area. This is:
You know that the area of the smaller trapezoid is 771 m², then you can set up the following proportion, where "x" is the area of the larger trapezoid. Then you have:
Now you must solve for "x". Therefore, you get that the area of the larger trapezoid is:
Answer:
Isosceles triangle
Step-by-step explanation:
for all 
in [-3, 0], so 
is non-decreasing over this interval, and in particular we know right away that its minimum value must occur at 
.
From the plot, it's clear that on [-3, 0] we have 
. So
for some constant 
. Given that 
, we find that
so that on [-3, 0] we have
and
Im sure its <span>For any x-value, the y-value of the exponential function is always smaller.</span>
Use Pythagorean theorem
a^2 + b^2 = c^2
a = 9, b = x, c = 18
9^2 + x^2 = 18^2
81 + x^2 = 324
x^2 = 243
x = 15.58846
Round to nearest tenth
Solution: x = 15.6
