Letter E is correct.
Area of equilateral trianlge= (1/2) tiime a^2 square root 3
Equation for the base is = x^2+y^2 =9
at x ,
y= square root (9-x^2)
Side of triangle a= 2y
d times Volume = (1/2)a^2 square root 3 dx
d times V= (square root 3) (9-x^2) dx
V= square root 3 INT (9-x^2) dx
-3V= 2square root INT (9-x^2) dx
0
V= 2 square root 3 ( 9x-x^3/3)
V=2 square root 3 ( 27-9)
V= 36 square root 3
The answer is E.
Answer:
b = 11
Step-by-step explanation:
the standard form of a quadratic equation is ax² + bx + c = 0 ( a ≠ 0 )
given
x² + 28 = - 11x ( add 11x to both sides )
x² + 11x + 28 = 0 ← in standard form
with b = 11
Answer:
Option C
Step-by-step explanation:
sorry if I'm wrong..
In order to find the perimeter, we need to have the length and the width. We are told that the area of the rectangle is 42. We will use that in the area formula, length times width, to solve for w. 42 = 7w so w = 6. The length is 7 and the width is 6. The perimeter formula for a rectangle is P = 2L + 2W. We have both the length and the width now, so we fill in accordingly. P = 2(7) + 2(6). And P=14+12. The perimeter then is 26 inches.

The diagram and complete question is shown below. We know that the length (L) of the living scale in the drawing is:
We also know that the scale is:
Then, by using proportion we have:
