Answer:
<em>π/2 and π/3</em>
Step-by-step explanation:
Given the equation 2cos²x - cosx = 0, to find the solution to the equation, we will follow the following step.
let P = cosx
The equation becomes 2P²-P = 0
P(2P-1) = 0
P = 0 and 2P-1 = 0
P= 0 and P = 1/2
Since P = cosx
cosx = 0 and cos(x) = 1/2
If cos(x) = 0
x = cos⁻¹0
x = 90⁰
x = π/2
If cos(x) = 1/2
x = cos⁻¹1/2
x = 60⁰
x = π/3
<em>Hence the solutions to the equation are π/2 and π/3.</em>
Slope=rise/run
this one
slope=increase in money/increase in time
from 412 to 549 that is 137, increase 137
from 1990 to 1999, that is 9 years, increase 9 years
slope=$/t
slope=137/9
slope=15 and 2/9
Answer:
assets to be overstated
Step-by-step explanation:
Given that a credit to an asset account was posted to an expense account.
We know that debit all comes in and credit all goes out for asset account
When asset account has to be credited there is a sale of asset and hence asset has to be reduced in value.
If wrongly posted to expenses account, then expenses would be credited by that amount. This will give assets a higher value and expenses a lower value.
When expenses are lower, profits high and hence capital would be ovestated.
So correct option is
assets to be overstated
1cm / 50 km = 3cm / x km => x = 3 cm * [50 km / 1 cm] = 150km
Answer: 150 km
