The scale factor to convert Figure A to B is (0.5)
Step-by-step explanation:
Step 1; To determine the scale factor, we need to know the dimensions of the shape before scaling and its dimensions after scaling. From the given diagram, figure A has a base length of 6 units while its height is 4 units. Figure B has a base length of 3 units and a height of 2 units.
Step 2; To find the scale factor, we divide a particular dimension from figure B with the same dimension in figure A.
The base length of figure B /the base length of figure A = =
,
Similarly, the height of figure B / the height of figure A = =
.
So by multiplying figure A with scale factor we get figure B.
Answer:
= log(3)
Step-by-step explanation:
Given equation:
now,
we know the properties of log function as:
1) log(A) + log(B) = log(AB)
2) log(A) - log(B) =
3) log(Aᵇ) = b × log(A)
therefore,
using property 3 we get
or
now,
using the property 2 we get
⇒ log(4) + log(3) + log(1) - log(4)
or
⇒ log(3) + log(1)
now,
using the property 1, we get
⇒ log(3 × 1)
or
⇒ log(3)
