Answer:
2372
Step-by-step explanation:
You would do the equation 2332-372+412
Answer: t = 6 s
Step-by-step explanation:
When Rose hit the water, the height of the jump is 0, so: h(t) = 0.
Resolving it, we have:
-16t² + 16t + 480 = 0
To simplify the second degree equation, divided it by 16:
-t² + t + 30 = 0
Now, solve the equation using Bhaskara:
Δ = 1² - 4. (-1) . 30
Δ = 1 + 120
Δ = 121
t = 
t₁ =
= - 5
t₂ =
= 6
Since time can be negative, it took t = 6s for Rose to hit the water.
Answer:
If:
(1)
And we have to rewrite the following expresion in terms of
:
(2)
Firstly we have to rearrange the right side of equation (2) in terms of
, factorizing by the common factor:
Then, we can substitute
by
:
And set it equal to zero:
>>>>This is the resulting equation
Now, each term of an algebraic expresion (like the equation above) is composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).
In this case, the variable is
and the number that multiplies the variable (the coefficient) is
, whereas the constant (which is the term with no variable) is
