The area of a isosceles trapezoid height of 8 base of 10 base of 15

Mathematics
1 answer:
ikadub [295]3 years ago
6 0

Answer:

A = 100 un^{2}

Step-by-step explanation:

You have to use the area of a trapezoid formula:

A = \frac{h}{2}(a + b)

Now, substitute the values of the height and the bases:

A = \frac{8}{2}(10 + 15)

Finally, simplify the equation to solve for the area:

A = 4(25)

A = 100 un^{2}

Find the intercepts and graph the equation. 7x +5y=12
vazorg [7]

Answer:

y-intercept: (0, 12/5) or (0, 2.4)

x-intercept: (12/7, 0) or (1.714, 0)

Step-by-step explanation:

The y-intercept is the point where the graph crosses the y-axis. That means, the point (0, yi). To find yi, we have to substitute x by 0 in the equation.

7x + 5y=12

7*0 + 5y = 12

y = 12/5 = 2.4

y-intercept: (0, 12/5) or (0, 2.4)

The x-intercept is the point where the graph crosses the x-axis. That means, the point (xi, 0). To find xi, we have to substitute y by 0 in the equation.

7x + 5y=12

7x + 5*0 = 12

x = 12/7 = 1.714

x-intercept: (12/7, 0) or (1.714, 0)

Finally, the graph is shown below.

Evaluate log3^8, given log3^2 is equivalent to 0.631
elixir [45]

We will use the followin property of logarithms:


log(a^b) = b log(a)


So, we have


log(3^2) = 2 log(3) = 0.631


If you multiply both sides by 4, you get


8log(3) = log(3^8) = 2.524
