Answer:
1. Factorization method
2. Formula method
3. Completing the square method
4. Graphical method
Step-by-step explanation:
There are four methods of solving quadratic equation:
1. Factorization method
2. Formula method
3. Completing the square method
4. Graphical method
1. Factorization method: Use factorization method when the quadratic equation can easily be factorize.
Example: x^2 - 4x - 12 = 0
(x-2)(x+6)
2. Formula method: This can be used when factoring the quadratic equation looks difficult or you are given instruction to use formula method
3. Completing the square method: Use completing the square method when you are instructed to do so.
4. Graphical method: This method is used when instructed to find x intercept.
Answer:
The answer is A
Step-by-step explanation:
Answer:
The relationship ⇒ <u>25x + 40y = 12,250</u>
Step-by-step explanation:
The number of student memberships = x
The number of adult memberships = y
The monthly membership fee for a student = $25
The monthly membership fee for an adult = $40
The total fee = 25x + 40y
Al's Athletic Club receives $12,250 in membership fees for the month of January.
So, the relationship between x and y is:
<u>25x + 40y = 12,250</u>
Answer:
The order of the number of the answers from top to bottom in the boxes are: 5, 6, 3, 1, 4, 2
The sinusoidal function that passes through (0,-6), has a period of 12 and an amplitude of 3 will be y = 3 sin 12x - 6.
What is a sinusoidal Function?
It is a function that repeats itself in a particular time interval.
The equation is given as
y = Asin (ωx + Ф) + k
We have
Amplitude (A) = 3
Period (ω) = 12
Phase difference (Ф) = 0
Then the equation will be
y = 3 sin 12x + k
The function is passing through (0, -6). Then we have
-6 = 3sin (12 × 0) + k
-6 = k
Then the equation will be
y = 3 sin 12x - 6
