Answer:
see below
Step-by-step explanation:
The base is 16ft
The height is 10 ft
We can find the area by
A = bh
A = 10*16 = 160 ft^2
Answer:
sin F = a/c
Step-by-step explanation:
The sin ratio by definition for a given angle is the side opposite that angle over the hypotenuse. The only thing that will never change sides in a right triangle is the hypotenuse. In other words, no matter what angle you look at, while the side opposite one angle may be the adjacent side to a different angle, the hypotenuse is always the hypotenuse. That means that c is the hypotenuse in our triangle. The side opposite angle F is a, so the sin of F = a/c.
Since quadratic coefient is 1 (term in front of x^2)
take 1/2 of linear cofient (12) and square it
12/2=6, 6^2=36
add that to both sides
x^2+12x+36=-11+36
factor perfect square
(x+6)^2=25
sqrt both sides and take positiv and negative roots
x+6=+/-5
minus 6 both sides
x=-6+/-5
x=-6+5 or x=-6-5
x=-1 or -11
answer is {-11,-1}
Answer:
D
Step-by-step explanation:
yes it is.
start by multiply by 4 to get rid of the fraction on x
4 () = 4(4) + 4()
x = 16 + 8y/3
Then by 3 to get rid of that one
3(x) = 3(16) + 3()
3x = 48 + 8y
Then subtract 8y from both sides to get
3x - 8y = 48
The factors would be (x-9)(x+4).
You can use the decomposition method to find this. I personally use the chart method so I do not necessarily know how to explain the decomp method in detail. However the idea and end goal are the same for both of them.
Try to find what multiplys to the last part of the polynomial but will add to the middle part.
To check your work/factors you can try multiplying/foiling them out again to see if you get your original polynomial.
