Let the maximum height of the top of the slide be h.
Now we can write:
sin 27=h/7.4
Rearranging the equation gives:
h=7.4 sin 27

Answer:
- perimeter = 6+2√73 ≈ 23.09 units
- area = 24 units²
Step-by-step explanation:
It can help to draw a figure.
The altitude of this isosceles triangle is 8 units, and it splits the base into equal lengths of 3 units. Using the Pythagorean theorem, we find the length of a side to be ...
BC = AC = √(3² +8²) = √73
The perimeter is the sum of the lengths of those two sides and the base:
P = 2(√73) +6 ≈ 23.088 . . . units
The area is given by the formula ...
A = 1/2bh
A = (1/2)(6 units)(8 untis) = 24 units²
__
The perimeter is 6+2√73 ≈ 23.09 units.
The area is 24 units².
when r = c is the break even point.
since r = 14x and c = 12x + 36000, then the break even point is when 14x = 12x + 36000
subtract 12x from both sides of this equation to get 14x - 12x = 36000.
combine like terms to get 2x = 36000.
divide both sides of this equation by 2 to get x = 18000.
that'a our answer.
the revenue will be equal to the cost when 18000 units are sold.
revenue = 14 * 18000 = 252000.
cost = 12 * 18000 + 36000 = 252000.
Answer:
Step-by-step explanation:
2x-4y=12.........(1)
-x+2y=-6..........(2)
Multiply equation (2) by 2
-2x + 4y = -12........(3)
Adding (3) from (1)
2x + (-2x) - 4y + 4y = 12 + (-12)
2x - 2x - 4y + 4y = 12 - 12
Ox -0y = 0
No solution
First multiply (3x-7) and (2x+5)
i already did the multiplication so i am writing the answer
(3x-7)(2x+5)
6x^2+x-35
a is 6
b is 1
c is -35
if you want me to share how i did the multiplication then do let me know
