I NEED HELP PLEASE, THANKS! :) Find the area of the triangle with a = 19, b = 14, c = 19. Round to the nearest tenth. (SHOW WORK)

 123.6 units²

Step-by-step explanation:

Since it is an isosceles triangle, we can draw a median from the ap ex (b) to the base (ac) to create a right triangle at point (d). Then we can use the Pythagorean Theorem to find the height (bd) of the triangle.

(dc)² + (b d)² = (bc)²

 7²  +  (b d)² =  19²

          (b d)²  = 19² - 7²

          (b d)² = 312

           b d  = 17.66

A = (1/2) base x height

  = (1/2) ac x b d

  = (1/2) 14 x (17.66)

   = 7(17.66)

   = 123.6

step-by-step explanation:

divided 3/4 and 6

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
