Step-by-step explanation:
I am not sure what your problem here is.
you understand the inequality signs ?
anyway, to get
6×f(-2) + 3×g(1)
we can calculate every part of the expression separately, and then combine all the results into one final result.
f(-2)
we look at the definition.
into what category is -2 falling ? the one with x<-2, or the one with x>=-2 ?
is -2 < -2 ? no.
is -2 >= -2 ? yes, because -2 = -2. therefore, it is also >= -2.
so, we have to use
1/3 x³
for x = -2 that is
1/3 × (-2)³ = 1/3 × -8 = -8/3
g(1)
again, we look at the definition.
into what category is 1 falling ? the one with x > 2 ? or the one with x <= 1 ?
is 1 > 2 ? no.
is 1 <= 1 ? yes, because 1=1. therefore it is also <= 1.
so we have to use
2×|x - 1| + 3
for x = 1 we get
2×0 + 3 = 3
6×f(-2) = 6 × -8/3 = 2× -8 = -16
3×g(1) = 3× 3 = 9
and so in total we get
6×f(-2) + 3×g(1) = -16 + 9 = -7
The height will be six times what is on the drawing.
6 4/5 x 6 = 36 24/5 = 40 4/5 inches tall.
Answer:
c ?
Step-by-step explanation:
Answer:
Arithmetic
An = A[n - 1] + 3/5
An = 3/5[n]
Step-by-step explanation:
Number of days = 5
Number of chocolate = 3
Computation:
Recursive:
Number of chocolate eat per day = 3/5
So,
First term a1 = 3/5
So,
An = A[n - 1] + 3/5
Explicit:
An = 3/5 + 3/5[n-1]
An = 3/5[n]
Answer:
f = 16
Step-by-step explanation:
Isolate the variable, f. Note the equal sign, what you do to one side, you do to the other. Multiply 8 to both sides of the equations:
2 = (f/8)
2(8) = (f/8)(8)
f = 2 * 8 = 16
f = 16 is your answer.
