Answer:
i need an answer to this
Step-by-step explanation:
4) 41/4, 14/4, 55/6, 34/7,60/8, 47/9, 27/6, 48/5, 31/3, 50/7,
5a) 132/6= 22
b) 146/9= 16.22
c) 147/2= 73.5
d) 107/4= 26.75
e) 156/8 = 19.5
f) 148/9 = 16.44
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
-----> equation in vertex form
therefore
the answer is the option C
To figure out the solution in a problem related to calculate maximum or minimum of something, you've to derive the involved equation, and make it equal to 0, solving the x.
So:
y = -0'296x² + 2'7x
y' = -0'592x + 2'7
0 = <span>-0'592x + 2'7
</span><span>-0'592x = 2'7
</span>x = 4'56
And if we substitute 4'56 on the first equation:
y = -0'296·<span>4'56² + 2'7·4'56
y = 6'16
So the length of the jump is 4'56cm, and the height 6'16cm.</span>
