to find the hypotenuse (or the ramp in question 4) you can use the equation
with a and b being the 3 feet and 9 feet and c being the unknown (ramp).
So if you plug 3 and 9 into the equation, it looks like this.
then square them.
simplify.
take the square root of both sides.
is approx. 9.5 so the answer would be H.
Answer: 7x+5
Step-by-step explanation:is that a 1 or I
need clearly
Answer:
20 N
Step-by-step explanation:
because of newton's second law you will use this equation F=ma which means force= mass*acceleration
so your problem should look like this 5*4=20
Answer:
<h2>
f⁻¹(x) = ∛(x+1)</h2>
Step-by-step explanation:
Given the encoded message defined by the function f(x) = x³-1, the inverse function that the decoder would need when the message is received can be expressed as thus:
let the inverse of the function be represented as y such that y = x³-1.
Making x the subject of the formula from the equation above;
x³ = y+1
Taking the cube root of both sides:
∛x³ = ∛(y+1)
x = ∛(y+1)
replacing y with x:
y = ∛(x+1)
f⁻¹(x) = ∛(x+1)
The encoded message is the inverse function ∛(x+1)
Answer:
0.75
Step-by-step explanation:
Given a geometric sequence:
The common ratio is derived by dividing any next term by the preceeding term.
That is:
In the geometric sequence: 4,3,9/4
Common ratio,
The common ratio of the given geometric sequence is 0.75.
