The rate of change for both functions is 2.
The equation for area of a triangle is 0.5*base*height, so when you halve both the base and height, the area gets divided by 4.
The area of the first triangle is 0.5*80*40 = 1600 cm^2.
6 1/4 cm^2 is the same as 25/4 cm^2.
Now, we have to see how many times 1600 cm^2 can be divided by 4 to get 25/4 cm^2.
Area of second triangle: 1600/4 = 400
Area of third triangle: 400/4 = 100
Area of fourth triangle: 100/4 = 25
Area of fifth triangle = 25/4
So, the fifth triangle has an area of 6 1/4 cm^2.
The pattern would be the area of the nth triangle =
Answer: A) 24 to the square root of 3
Step-by-step explanation: Hope this helps!
Answer:
68 in.
Step-by-step explanation:
The rectangle is 60in., and you can find the area of a triangle by multiplying the height and the width, then dividing it by 2. The height is four, and the width is 4, 4x4 is 16, divided by 2 is 8.
