Answer:
im sorry but the picture is black-
Step-by-step explanation:
There isn't really any work to show, but that is correct!
The formula for exponential growth is y=a(1+r)
![^{x}](https://tex.z-dn.net/?f=%20%5E%7Bx%7D%20)
. Where a is the initial value when time is 0 (100 in this case). r is the growth rate, we can see that the growth is 10%. And x is how much time has passed, we want to find out how many trucks after 9 years.
So we would plug the values in to get y=100(1+.1)
![^{9}](https://tex.z-dn.net/?f=%20%5E%7B9%7D%20)
. Solving this gives us 235.79, so we would round up to 236, and our answer would be 236 trucks registered in the city in year 9.
Edit: The x and the 9 are exponents, the formatting made them look a bit weird.
<span>None, because with triangles the sum of the two shorter side lengths (5 m + 5 m) needs to be equal to or greater than the length of the longest side (15 m). In this case, the sum of the two shorter sides is 10 m, which is less than 16 m, so a triangle cannot form.</span>
You can find the area of Bonnue's backyard by comparing the hypotenuse of the garden to the hypotenuse of the back yard. If the hypotenuse of the garden is 10 (with the side lengths being 6, 8 and 10 - the longest is always the hypotenuse) and the hypotenuse of the back yard is 30, this is a scale factor of 3 (3 times longer).
This means the other two sides would also be 3 times longer.
6 yards x 3 = 18
8 yards x 3 = 24
To find the area using these dimensions, you will use the formula for finding the area of a triangle.
A = 1/2bh
A = 1/2 x 18 x 24
A = 216 square yards
The area of the backyard is 216 square yards.
