Answer:
x = ±
Step-by-step explanation:
x² = 10 ( take square root of both sides )
x = ±
Answer:
52
Step-by-step explanation:
Given the the equation h(t) =- where t is the time in second
So to find the ball's maximum height we can apply the vertex formula:
t=
to find the "x" value of the vertex, then plug that value into the original equation as a substitute for "x".
Standard quadratic form is:
=> a=15, b=30 in our given equation
<=> t =
When t =-1 we have h(t) = = 52
So the ball's maximum height is: 52
Hope it will find you well.
Answer:
8th Month
Step-by-step explanation:
- Company A is offering $10,000 for the first month and will increase the amount each following month by $5000.
- Company B is offering $500 for the first month and will double the amount each following month.
<u>For Company A</u>
Company's A payment increases by a certain amount, it is therefore an Arithmetic Growth.
The nth term for an arithmetic progression is given by:
First term, a=$10,000; Common Difference,d=$5000
<u>For Company B</u>
Company's B payment doubles every month, it is therefore a Geometric Growth.
The nth term for an geometric progression is given by:
First term, a=$500; Common Ratio,r=2
We want to determine at which month, n Company B's Monthly Payment will exceed that of company A.
Using the nth term formula derived above:
In the 8th Month, the payment of Company B will exceed that of company A.
Answer:
Step-by-step explanation:
=> 3b²/3b = b
=> 9b/3b = 3
=> 4/3b = 4/3b
Therefore the final answer would be;
Hope this helps!
Answer:
21
Step-by-step explanation:
Mean is the average of the objects
With five people, the mean is the average age of these people so what did you divide 5 into to get 39.
5 × 39 = 195
After a person enter the room, total 6 in the room with a mean of 36.
6 × 36 = 216
Now the age of the person who entered the room 216 - 195 = 21
