Answer:
13.76
Step-by-step explanation:
We want year 10; this means we substitute 10 in place of x:
y=-0.34(10²)+4.43(10)+3.46
y = -0.34(100)+4.43(10)+3.46
y = -34+44.3+3.46 = 13.76
Symbolically, write this:
C
7 5. Know how to evaluate that?

Answer:
26
Step-by-step explanation:
To evaluate this expression, all we have to do is substitute the given values of the variables into the expression. That is, replace every
in the expression with a
and every
in the expression with a 5.
Doing so, we get:

(Substitute given values into the expression)
(Evaluate exponential term)
(Add)
