Answer:
You can find the answer by using the formula t=-b/2a
Step-by-step explanation:
Remember the maximum height will be at the vertex. The x value of the vertex is your time, so use x=-b/2a except that t is your x. Then if it had also asked what the height was, you would plug that answer into your equation to find the y value of the vertex. Pretty sure your teacher is just asking you to find the x though:)
Step-by-step explanation:
If 15÷C=3 , 15÷3=5 and 15-5=10, 10-5=5, 5-5=0 The answer is 3
Answer:
(x + 5)2 + 2 = 42.5
List of steps
2(x)+2(5)
2x+10
2x+10+2=42.5
2x+12=42.5
2x=42.5-12
2x=30.5
2x/2=30.5/2
x=30.5/2
x=15.25
x=15.25
Step-by-step explanation:
(x + 5)2 + 2 = 42.5
Solve (x+5)2 first
2(x)+2(5)
2x+10
Now the equation
2x+10+2=42.5
2x+12=42.5
Make 2x the subject
2x=42.5-12
2x=30.5
Divide both sides of the equation by 2
2x/2=30.5/2
x=30.5/2
x=15.25

Answer:
1.4
Step-by-step explanation:
We have been given that the number of raisins in a box of a popular cereal is normally distributed, with a mean of 133 raisins per box and a standard deviation of 10 raisins. My cereal box has 147 raisins.
To find the z-score for this box of cereal, we will use z-score formula.
, where,
z = Z-score,
x = Sample score,
= Mean,
= Standard deviation.
Upon substituting our given values, we will get:
Therefore, the z-score for this box of cereal is 1.4.
