Answer:
Quadratic equation has equal roots
We know that quadratic equation has two equal roots only when the value of discriminant is equal to zero. We know that two roots of quadratic equation are equal only if discriminant is equal to zero.
Step-by-step explanation:
<u>144</u>
So, c must be 144 to make the trinomial a perfect square.
ANSWER
Period: 2π , amplitude: 4
EXPLANATION
The graphed function is

The amplitude of this function is

The period is 2π because there is no phase shift hence the period is still equal to the parent function.
Period: 2π , amplitude: 4
To do this we will just DIVIDE. Lets Divide:-
15 ÷ 4 = 3.75
Check our work:-
3.75 × 4 =15
So, to finish 1 project you have 3.75 days.
