Your answers are wrong. the function f(x) is like a factory. you put in something ( a number) and it will spit you out something else (a different number depending on the function). your function, f (x)= -2x+1
you can put anything in that function. let say k.
f(x=k) = -2k+1. you just replace the x with k.
in this particular problem they way f(-2) ,f(0), f(1) and f(2).
here are the results
f(x=-2) = f(-2) = -2×(-2)+1 =5
f(x=0) = f(0) = -2×(0)+1 =1
f(x=1) = f(1) = -2×(1)+1 =-1
f(x=2) = f(2) = -2×(2)+1 =-3
The maximum profit is the y-coordinate of the vertex of the parabola represented by the equation.
The maximum value is 6400, but the profit is given in hundreds of dollars, so multiply the value by 100.
The maximum profit the company can make is $640,000.
Answer:
Future value A = P(1+r)^(t)
A = 27000(1+0.065)^1
A = 27000(1.065)
A = 28755 units
Corrected question;
The price of a new Ford F-150 has increased by 6.5% this year. If the price was 27,000 last year, which expression can be used to calculate the price of the new Ford this year
Step-by-step explanation:
Applying the future value formula;
A = P(1+r)^(t) .....1
Where;
A = final amount/value
P = initial amount/value (principal)
r = rate yearly
t = time in years
Given;
P = 27,000
r = 6.5% = 0.065
t = 1 year
Substituting the given values;
So A = 27000(1+0.065)^1
A = 27000(1.065)
A = 28755 units
Hello!
The chance of getting a football card is 7 / 10
The chance of then getting a basketball card is 3 / 10
Multiply these two numbers
7/10 * 3 / 10 = 21/100
21/100 = 0.21
The answer is 0.21 or 21%
Hope this helps!
