Answer:
g(f(2)) = 41
b)41
Step-by-step explanation:
g(f(2)) = 41
f(2)= 2(2²) + 5 = 13
So g(f(2)) → g(n = 13)
g(n = 13)→ 3(13) + 2 = 41
Answer:9
Step-by-step explanation: Problem. Evaluate the expression log2
1
8 without using a calculator.
Solution. We know that 1
8 = 2−3
. Therefore, log2
1
8 = −3.
Problem 6
Problem. Write the exponential equations as logarithmic equations.
(a) 272/3 = 9.
(b) 163/4 = 8.
Solution. (a) The base is 27 and the exponent (logarithm) is 2/3. So the logarithmic
equation is
log27 9 =
2
3
.
(b) The base is 16 and the exponent (logarithm) is 3/4. So the logarithmic equation
is
log16 8 =
3
4
.
Problem 9
Problem. Sketch the graph of the function y = 2x by hand
Answer:
House coordinate = (5, 1)
Library coordinate = (10, 13)
Step-by-step explanation:
Given :
House coordinate = (5, 1)
Library coordinate = (10, 13)
Distance between house snd library :
Distance = sqrt[(x2 - x1)² + (y2 - y1)]
x1 = 5, x2 = 10, y1 = 1, y2 = 13
Distance = sqrt[(10 - 5)² + (13 - 1)²]
Distance = sqrt[(5² + 12²)]
Distance = sqrt(25 +144)
Distance = sqrt(169)
Distance = 13
I confused ! I don't get what your trying to say please explain better !
