Answer:
a(9) = 150*(0.4)^8 = 0.098304
Step-by-step explanation:
This is a geometric sequence, because each new term is 0.4 times the previous term.
The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1). Here, with a(1) = 150 and r = 0.4, we have:
a(n) = 150*(0.4)^(n - 1), and so
a(9) = 150*(0.4)^8 = 0.098304

Answer:
Its a Translation because all they did with it was move it. It never changed size or shape.
Step-by-step explanation:
> How tall was the tree when Vlad moved into the house?
We know that the tree grew by 26 cm per year, the current
height is 292 cm and 4.5 years have already passed, therefore the original
height was:
original height = 292 cm – (26 cm / year * 4.5 years)
original height = 175 cm
> How many years passed from the time Vlad moved in
until the tree was 357 centimeters tall?
Calculate for time using the formula:
time = (current height – original height) / 26
time = (357 cm – 175 cm) / (26 cm/ year)
<span>time = 7 years</span>
To find the centroid, follow these steps: Step 1: Identify the coordinates of each vertex. Step 2: Add all the x values from the three vertices coordinates and divide by 3. Step 3: Add all the y values from the three vertices coordinates and divide by 3. Would be your answer
