Step-by-step explanation:
So first of all we plug in 1 into f(x) and the result of that into g(x).
f(1)=(1)^2-3(1)+5
=1-3+5
=3
g(3)=(3)(22)-2(3)
=66-6
=60
Answer:
Step-by-step explanation:
Given function:
As per question statement:
Initial temperature of bottle is 70 
.
i.e. when time = 0 minutes, f(t) = 70
After t = 3, f(t) = 42
Hence, the value is:
To find the inverse, interchange the variables and solve for y.
f^−1(x)=−25+5x/2
Answer:
rectangles are similar figures, thus if scaled copies of each other then the ratios of corresponding sides must be equal
compare ratios of lengths and widths
rectangles A and B
k = = ← ratio of lengths
k = = ← ratio of widths
scale factors are equivalent, hence rectangle A is a scaled copy of B
rectangles C and B
k = = ← ratio of lengths
k = = ← ratio of width
scale factors (k ) are not equal, hence C is not a scaled copy of B
rectangles A and C
k = = ← ratio of lengths
k = ← ratio of widths
the scale factors are not equal hence A is not a scaled copy of C
