Mischa wrote the quadratic equation 0 = –x2 + 4x – 7 in standard form
The standard form of quadratic equation is

When y=0 then the standard equation becomes

Now we compare the given equation
with
and find the value of a, b,c
-x^2 can be written as -1x^2
a= -1 , b=4 and c=-7
The value of c is -7
Answer:
250 cookies
Step-by-step explanation:
The employee burns 55 chocolate chip cookies
if this represented 22% of the days production
Let x = the total production of cookies for the day
how many cookies did you plan on producing that day?
22% of x = 55
22 / 100 * x = 55
0.22x = 55
Divide both sides by 0.22
x = 55 / 0.22
= 250
x = 250 cookies
Therefore, the total production of cookies for the day is 250
The correct answer is y=x+4.
Answer:
2.44746×10⁶
Step-by-step explanation:
R=(3.8×10⁵)²/5.9×10⁴
=3.8²×10¹⁰/5.9×10⁴
=1.444×10¹¹/5.9×10⁴
=1.444×10⁷/5.9
=361×10⁷/1475
=2.44746×10⁶
