The area of a trapezoid is found using the formula, A = ½ (a + b) h, where 'a' and 'b' are the bases (parallel sides) and 'h' is the height (the perpendicular distance between the bases) of the trapezoid.

STatiana [176]

Answer:

To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and f^{-1}(x)= \frac{ln\ x+4}{2}

Step-by-step explanation:

Data provided in the question

f(x) = e^2x - 4

Now

to find the inverse let

So,

y = e^2x - 4

Now

Replace x and y

Therefore

x = e^2y - 4

Now compute the value of y

So,

x + 4 = e^2y

Now take ln on both sides:

The equation is

ln(x+4) = ln(e^2y)

ln(x+4) = 2y

y = ln(x+4) ÷ 2

f^{-1}(x)= \frac{ln\ x+4}{2}

Therefore,  To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and f^{-1}(x)= \frac{ln\ x+4}{2}

Find the area of these shapes AND explain your method <br> Can some one help me :((
-Dominant- [34]

Answer:

Triangle - 21 units

Trapezoid - 65 units

Step-by-step explanation:

  • Because this triangle and trapezoid are reflections of each other when split in half, remove the highlighted parts to make them a rectangle. When made into a rectangle, you can use the formula length * width to find the area of either shape (trapezoid or triangle).
  • Note you won't be able to do this when solving for the area of ALL trapezoids and triangles.

The width of a rectangle is 19 meters more than the length. The perimeter is 242 meters. Find the length and width.
dimaraw [331]

Answer:

The length of the rectangle is 51 meters and the width is 70 meters.

Step-by-step explanation:

Let us assume that the length of the rectangle is L and the width of the same rectangle is W.

it is given in the problem that, the width of the rectangle is 19 meters more than the length.

Hence, L+19 =W ......(1)

Again, the perimeter of the rectangle is given by 2(L+W), which is given to be 242 meters.

So, 2(L+W) =242, ⇒L+W =121 ..... (2)

Now, solving equations (1) and (2) by substitution method, we get,

L+(L+19) =121, ⇒2L =102, ⇒ L =51 meters.

Now, from equation (1), W=L+19 =70 meters.

Therefore, the length of the rectangle is 51 meters and the width is 70 meters. (Answer)
