Answer:
8
Step-by-step explanation
All you have to do is how many times it goes up. it goes up 8 times so 8 is your answer
<span>Simplifying
5x2 + -35 = 0
Reorder the terms:
-35 + 5x2 = 0
Solving
-35 + 5x2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '35' to each side of the equation.
-35 + 35 + 5x2 = 0 + 35
Combine like terms: -35 + 35 = 0
0 + 5x2 = 0 + 35
5x2 = 0 + 35
Combine like terms: 0 + 35 = 35
5x2 = 35
Divide each side by '5'.
x2 = 7
Simplifying
x2 = 7
Take the square root of each side:
x = {-2.645751311, 2.645751311}</span>
We make a drawing to find the relationship between the angle and the sides
given
dh/dt=4m/sec
we get
tan(x)=h/40
where x is the angle and h is the height
take the derivitive of both sides
1/cos²(x)(x)dx/dt=
1/cos²(x)dx/dt=
1/cos²(x)dx/dt=
solve for dx/dt
times both sides by cos²(x)
dx/dt=
remember that dh/dt=4
also, solve for the angle at that time
h=40 and base=40 so x=45 degrees (pi/4 radians)
input that
dx/dt=
dx/dt=
dx/dt=0.05
A is the answer
No, 1/3 is greater than 1/6.
1/3 converts to 2/6.
2/6 > 1/6
X^2-6x-27 = (x-9)(x+3), therefore (a) is the correct answer
