Answer:
hello :
Step-by-step explanation:
f(x) = 2x²+5√(x-2)
f(x) exist : x - 2 ≥ 0 : x ≥ 2
The domain for f(x) is all real numbers "greater" than or equal to 2
<span>The variance method is as follows.
-Sum the squares of the values in data set, and then divide by the number of values in data set
- From that, subtract the square of the mean (add all values and divide by number of values in the data set)
Our variance is
<span>
Since variance has to be 14, we set
and solve for m
quadratic formula
-4 doesnt' work as it is not a positive integer
m = 11

Answer:
Step-by-step explanation:
The diagram of the problem is drawn and attached.
Given that:
Also
137 - 16X = Y
Since Lorraine is picking blackberries in her backyard at a rate of 15 berries per minute, and after 16 minutes of picking, there are still 137 blackberries left to pick, to determine an equation that models how many berries are left (y) after x minutes of picking, the following calculation must be performed:
137 - 16X = Y
Thus, for example, after 5 minutes the calculation would be as follows:
- 137 - 16 x 5 = Y
- 137 - 80 = Y
- 57 = Y

Answer:
A. 7
Step-by-step explanation:
z ÷ (–7) = –1.
multiply each side by -7
z ÷ (–7)*-7 = –1.*-7
z = 7
