B is not a square, it’s a rectangle. It has a area of 5x6=30 cm^2
- f (x) = 3x² + x
- Find f (-5).
Given,
Now, we have to find f (-5). To find this, we just need to substitute -5 in the place of x.
So,
Answer:
18.5 in
Step-by-step explanation:
Let x be the length of board.
Actual width of board,b=1.5 in
Height of board,h==5.5 in
Density of wood=0.021lb/cubic in
Weight of wood=3.2 lbs
We know that
Volume=
By using the formula
Volume of wood=
Volume of wood=
Using the formula
Hence, the length of board=18.5 in
Answer:
2.39%
Step-by-step explanation:
Maxwell bought $15,000 worth of 52-week T-bills for $14,650
Therefore the rate of return on investment can be calculated as follows
= 15,000-14,650/14,650× 100
= 350/14,650 × 100
= 0.02389 × 100
= 2.39%
Hence the rate of return on this investment is 2.39%
