Answer:
<em>f(10)=290</em>
Step-by-step explanation:
<u>Function Evaluation</u>
Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.
We are given the function:
It's required to find f(10). We replace the x for 10:
Operating:
Thus, f(10)=290
An estimate for the number of ducks would be 62.
There were 30 the first day.
The second day, 8 of those 30 were there as well, so we subtract that from the 40 ducks and get 32.
Add 30 and 32 to get our estimate.
Answer: here a, b, and c are real numbers and a≠0. A solution to such an equation is called a root. Quadratic equations can have two real solutions, one real solution, or no real solution. If the quadratic expression on the left factors, then we can solve it by factoring. A review of the steps used to solve by the factory..

Answer:
1) 75 copies were sold
2)expected wage=720
Step-by-step explanation:
in this equation, y represents wages and x represents number of copies sold
lets take the trendline, y=6x+120
since the amount earnt is $570, we can take this to be our y variable
570=6x+120
450=6x
x=75
1) 75 copies r sold
2) this time we substitue the 100 for x
y=6(100)+120
y=600+120
y=720
2) expected wage=720
Answer:
32 degrees
Step-by-step explanation:
90 + 58 = 148
180 - 148 = 32
