Answer:
I believe the answer to be 387.11
Step-by-step explanation:
A=1/4√5(5+2√5) a°2=1/4√5•(5+2•√5)•15°2=387.10742 cm°2
Rounded= 387.11
Answer:
12x -y = 24
Step-by-step explanation:
You want a line through points (4, f(4)) and (6, f(6)). Evaluating the function, we find the points are (4, 24) and (6, 48). In the 2-point form of the equation for a line, we find ...
y = (y2 -y1)/(x2 -x1)(x -x1) + y1
y = (48 -24)/(6 -4)(x -4) +24 . . . . filling in the values
y = 12(x -4) +24 . . . . . . one form of the equation for the secant
12x -y = 24 . . . . . . . . . . standard form equation of the line
__
The slope-intercept form of the equation is ...
y = 12x -24
Answer:
7.3 ft
Step-by-step explanation:
The information given represents a right angle triangle with the following:
reference angle = 52°
Adjacent side length = 5.7 ft.
Opposite side length = height of the statue = h
Applying the trigonometric ratio formula, we would have:

Multiply both sides by 5.7


(nearest tenth)
His answer was (x- +2) (x^2-9)
a) His mistake was he has x^2 in one of the parenthesis, to be fully factored you cannot have an exponent as part of the answer.
b) x^3 - 9x + 2x^2 -18
Reorder the terms:
x^3 +2x^2 -9x -18
Group the first two terms and the last two terms
(x^3 + 2x^2) -9x-18
Factor out the greatest common factor from each group:
x^2(x+2) - 9(x+2)
Factor the polynomial by factoring out the common factor once x+2:
(x+2) (x^2-9)
Rewrite 9 as 3^2:
(x+2) (x^2-3^2)
Factor one last time:
(x+2) (x+3) (x-3)
