Answer:
a) 2
b) 5
c) -1
d) x
Step-by-step explanation:
We know the properties of log function as:
1) log(AB) = log(A) + log(B)
2) 
3) log(aᵇ) = b × log(a)
also,
4) 
Given:
a. y = log₂(2²)
thus, using 3
y = 2log₂(2)
or using 4
y = 2 × 
or
y = 2 × 1 = 2
b. y = log₂(2⁵)
thus, using 3
y = 5 × log₂(2)
or using 4
y = 5 ×
or
y = 5 × 1 = 5
c. y = log₂(2⁻¹)
thus, using 3
y = -1 × log₂(2)
or using 4
y = -1 ×
or
y = -1 × 1 = -1
d. y = log₂(2ˣ)
thus, using 3
y = x × log₂(2)
or using 4
y = x ×
or
y = x × 1 = x
Around 35-45 minutes, but it depends on the size of the container.
Ok so 2cm on the blueprint is actually 7cm in real life
2:7=1:3.5
for every cm on the map, it is 3.5 times that in real life
so total legnths
17 times 3.5+18 times 3.5+18 times 3.5+19 times 3.5=
59.5+63+63+66.5=
252
answer is 252cm
Answer:
c
Step-by-step explanation:
Answer:
<h2>
</h2>
Step-by-step explanation:
Since the sequence above is a geometric sequence
For an nth term in a geometric sequence
<h3>
</h3>
where
a is the first term
r is the common ratio
n is the nth term
To find the common ratio divide the previous term by the next term
That's
<h3>
</h3>
So the common ratio / r = 7
the first term is - 1
Substitute the values into the above formula
<h3>
</h3>
We have the final answer as
<h3>
</h3>
Hope this helps you
