Find the area of the figure

Mathematics
1 answer:
sweet [91]3 years ago
4 0

Answer:

[See Below]

Step-by-step explanation:

✦ In this figure there are two shapes; A triangle and a square. So you'll need to know the area formula for both:

  ✧ Square ∼ s² (Side Squared)

  ✧ Triangle ∼ ½ × b × h

✦ So now just solve for each area:

  ✧ Square ∼ 15² = 225

  ✧ Triangle ∼  ½ × 15 × 3 = 22.5

✦ Now add each area together to get the total area:

  ✧ 225 + 22.5 = 247.5

Find the average rate of change of the function over the given interval.
Minchanka [31]

Answer:

Average rate of change = 20.2

Rate of change at the left endpoint :   f' (5) = 4t = 20

Rate of change at the right  endpoint : f' (5.1) = 4*5.1 = 20.4

Step-by-step explanation:

The average rate of change of the function

F(t) = 2t^2 - 1 ,  [ 5,5.1 ]

solution

\frac{f(5.1)-f(5)}{5.1 - 5} = \frac{2*(5.1)^2-1-(2*5^2-1)}{0.1}   = [ 2 ( 26.01 - 25 ) / 0.1 ]

= 2.02 / 0.1 = 20.2

Rate of change at the left endpoint :   f' (5) = 4t = 20

Rate of change at the right  endpoint : f' (5.1) = 4*5.1 = 20.4
