The answer would be 620000
Answer:
9feet
Step-by-step explanation:
Given the path of the toy modeled by the function f(x)=−x^2+4x+5, where x is the number of feet the toy is from Emmy and f(x) is the height of the toy.
AT maximum height, the velocity of the toy will be zero. Hence;
df(x)/dx = 0
-2x + 4 = 0
-2x = -4
x = -4/-2
x = 2
Get the maximum height;
Substitute x = 2 into the given function;
f(x)=−x^2+4x+5
f(2)=−2^2+4(2)+5
f(2) = -4+8+5
f(2) = 9feet
Hence the maximum height of the toy is 9feet
Answer:
l-60 – 13| = |-73| = 73 units
Step-by-step explanation:
Required
Distance between -60 and 13
Using absolute values, distance is calculated as:
Where
So, we have:
Take absolute value of -73
<em>Hence, option A answers the question</em>
Answer:
$1050
$54,600
Step-by-step explanation:
In this question, we are looking at calculating two things. We want to calculate the amount of commission made in a week and the amount made in a year.
Firstly, to calculate the amount of commission she made last week, we simply find the percentage.
Mathematically, this is equal simply to:
14% of $7,500 = 14/100 * 7500 = $1050
She made a commission of $1050 last week
Now, we are told this is the average she makes per week. We now want to calculate how much she makes per year. To do this, what we do is to multiply what she had made in a week by the number of weeks in a year.
The number of weeks in a year is 52. The amount she made is just 52 * $1050 = $54,600
