Answer:
the first one should be 5.28x10^-2 and the second one should be 3.2x10^6
Step-by-step explanation:
because with 0.0528 you move the decimal right twice. which makes it negative.
with 3,200,000 you assume that the decimal is at the end and move it between the three and the two. making it have 6 moves. since it moves left its positive
Answer:
a) 7/4 b) 5 c) 2
Step-by-step explanation:
Logrithmic Rule for a and b
Let a, M, N be positive real numbers.
a)
logaM - logaN = loga(M/N)
log9(7) - log9(4) = log9 (7/4)
b)
logaM + logaN = logaMN
log2 (x) + log2(9) = log2(45)
x9=45
(x9)/9 = 45/9
x = 5
c)
Change of base formula.
logb(x)=logd(b)/logd(x)
x log6(5) = log6(25) divide each term by log6(5)
x log6(5) / log6(5) = log6(25) / log6(5) Cancel common factor log6(5)
x = log6(25) / log6(5)
x = log6(5^2) / log6(5)
Expand log6(5^2) by moving 2 outside the logarithm.
x = 2log6(5) / log6(5) cancel the like term log6(5)
x = 2
Answer:
102°
Step-by-step explanation:
They're still corresponding angles... have you read any of these explanations?...
Is this multiplying or what??? Anyways try calculating those numbers so basically you need to calculate 28x2 or if you have to divide them or multiply them you would get the answer is very simple
Answer:
15
Step-by-step explanation:
5/15=3/v
5v=15×3
5v=75
5v/5=75/5
v=15
