Answer:
The question is asking to solve a problem that'll "add up", or in other words, makes sense; through the use of Trigonometric functions. The leaning ladder is the hypotenuse of 17ft, adjacent to that is a wall that measures 16.5ft above the ground. The angle both sides make must be <=70°. The function here is Opposite over Hypotenuse i.e 16.5/17 . We use the inverse operation of Sin which is Sin^(-1) to find if the angle is < or = to 70°. Using a calculator, we find the angle to be 76.06°, which is > more than, 70°.
Thus, the ladder will not be safe for its height and therefore won't make sense.
First play - 2
Second play + 35
Third play (after the first down) + 15
No they didn't get a first down. They got two of them.
The total gain was
-2 + 35 + 15 = 50 - 2 = 48 yards gained.
Answer: 16
Step-by-step explanation:
(50 - (2x9)) / 2 = 16
Answer:
C
Step-by-step explanation:
We are multiplying f(x) and g(x), which are the length and width. The area of a rectangle is a=l*w, so we can eliminate choice B.
Now, we have to find what f(x) * g(x) is
f(x) * g(x)
f(x) is 3x^2-2x and g(x) is 2x-3, so we can substitute them in
(3x^2-2x)*(2x-3)
Use FOIL to find the answer
F: 3x^2*2x= 6x^3
O: 3x^2* -3 = -9x^2
I: -2x*2x= -4x^2
L: -2x*-3= 6x
6x^3-9x^2-4x^2+6x
Combine like terms
6x^3-13x^2+6x
So, we know that f(x) *g(x) is 6x^3-13x^2+6x, and that it is the area (l*w), so choice C is correct.
