Answer:
The roots of the given quadratic function is and
Step-by-step explanation:
Given: Quadratic function
We have to find the roots of the given quadratic function
Since, roots of the quadratic equation is the points where the value of function is zero.
That is f(x) = 0
Consider the given function
Put f(b) = 0
Simplify , we have,
Taking square root both side, we have,
Simplify we have,
Thus, The roots of the given quadratic function is and
Answer:
Option D. 1 quart
Step-by-step explanation:
In a solution of 1 gallon we have to calculate the amount of cleaning solution will be needed.
Since mixture prepared will be in the ratio of 1 : 3 (cleaning solution : water)
So total amount of cleaning solution in 1 gallon = gallon
As we know 1 gallon = 4 quarts
so gallons = ()(4) = 1 quart
Therefore, 1 quart of the cleaning solution will be added.
1 quart
Given:
Question:
How much cleaning solution will you need to use?
The Process:
From the text above, we will mix the window cleaning liquid in a gallon bucket by mixing 1 part cleaner to 3 parts water. In other words, the ratio of the mixture between the cleaning solution with water is 1 : 3.
The sum of the ratios is 1 + 3 = 4, meaning that in a gallon bucket there are four parts.
Furthermore, based on this ratio we can state the composition in solution as follows:
Remember that .
Thus we needof cleaning solution to mix a gallon bucket of window cleaner.
a. One day, 200 kids’ tickets were purchased. What was the total cost of those tickets?
----------------- answer
Answer:
$1,050
Step-by-step explanation:
Simply multiply the cost per kid ticket and number of kids:
$5.25 x 200 = $1,050
The answer is D, i.e. the system was solved via elimination
If you multiply the first equation by 5, the system becomes
If you sum the two equations, you get
And so if you substitute the second equation of system A with this new equation, you'll get system B.
b. 5
c. 7
d. 9
e. 10
Melinda must removeatleast 5 pairs of socks to ensure that she has a pair of each color.
Option B is the correct answer.
We have,
To ensure that Melinda has a pair of eachcolor, she needs to remove at least one sock from each color until she has one sock remaining from each color.
Since she has 3 pairs of red socks, 2 pairs of black socks, and 5 pairs of white socks, the minimumnumber of pairs she must remove is the maximum of these numbers.
The maximum among 3, 2, and 5 is 5.
Therefore,
Melinda must removeatleast 5 pairs of socks to ensure that she has a pair of each color.
