Answer:
For the value of will be the same of .
Step-by-step explanation:
To determine for which value of , we need to apply the following identity () and solve numerically the resulting expression:
(1)
A quick approach is using graphic tool and looking for the value of such that . The result of the analysis is included below in the attached image. We find the following result:
For the value of will be the same of .
f(1) = -4
f(2) = 3
f(3) = 10
f(4) = 17
f(5) = 24
Step-by-step explanation:
Step 1:
Let f(n) = 7n - 11
Here we can put n= 1,2,3,4,5
Step 2:
Let us do it step by step.
f(1) = 7×(1) - 11 = 7 - 11 = -4
f(2) = 7×(2) - 11 = 14 - 11 = 3
f(3) = 7×(3) - 11 = 21 - 11 = 10
f(4) = 7×(4) - 11 = 28 - 11 = 17
f(5) = 7×(5) - 11 = 35 - 11 = 24
Answer:
29400
Step-by-step explanation:
Find the LCM
4900 = 2×2×5×5×7×7
168 = 2×2×2×3×7
Pick the larger number and multiply with the factors missing from the smaller number:
4900×2×3
=29400
