Answer:
-7/2 = -2(x-1/2)^2
Step-by-step explanation:
0 = –2x^2 + 2x + 3
Subtract 3 from each side
-3 = –2x^2 + 2x
Factor out the -2
-3 =- 2(x^2 -x)
Take the coefficient of x and divide by 2 and square it
-1 /2 = -1/2 ^2 = 1/4
Add it to each side Remember the -2 on the outside so we need to multiply it by -2
-2 *1/4 = -1/2
-3 -1/2= -2(x^2 -x +1/4)
-7/2 = -2(x^2 -x +1/4)
-7/2 = -2(x-1/2)^2
Answer:
Step-by-step explanation:
let denote grams of formed in mins.
For of we have:
of A and of B
Amounts of A,B remaining at any given time is expressed as:
of A and of B
Rate at which C is formed satisfies:
Apply the initial condition, ,to the expression above
Now at :
Substitute in X(t) to get
Answer:
No, 7a does not equal 56. If a = 7, then 7a would equal 7 * 7. And, 7 * 7 = 49.
<u>Answer:</u>
m² - 3m - 10
<u>Steps:</u>
(m + 2)(m – 5) = m² - 5m + 2m - 10
(m + 2)(m – 5) = m² - 3m - 10
