Find the volume of the prism.
Oliga [24]

9514 1404 393

Answer:

  420 mm³

Step-by-step explanation:

The volume is given by the formula ...

  V = Bh

where B is the area of the triangular base, and h is the height.

The triangular base area is given by the formula ...

  A = 1/2bh

  A = 1/2(10.5 mm)(10 mm) = 52.5 mm²

Then the volume of the prism is ...

  V = (52.5 mm²)(8 mm) = 420 mm³

Li Wei has several streams of income, as shown in the table. Some streams are active income and some are passive.
WARRIOR [948]

Based on the streams of income that Li Wei has, we can calculate that he has a total passive income of <u>$3,010.</u>

Passive income refers to income that is made without a person actively involving themselves in the activity generating the income.

In this scenario, the passive income sources are:

  • Stock dividends
  • Business investment interest
  • Royalties from a novel

Total passive income therefore is:

= 530 + 1,080 + 1,400

= $3,010

In conclusion, the total passive income is $3,010.

Solve the Method of variation of Parameters. y" - 3y' + 2y = 4e^3t
kirill [66]

Answer:

CF+PI=c_1e^{2x}+c_2e^{x}+2e^{3t}

Step-by-step explanation:

we have given y"-3y'=2y=4e^{3t}

this differential equation solution have two part that CF and PI

CALCULATION OF CF :

m^2-3m+2=0

m^2-2m-m+2=0

(m-1)(m-2)=0

m=1 and m=2

so CF=c_1e^{2x}+c_2e^{x}

CALCULATION OF PI :

PI =   \frac{4e^{3t}}{(m-1)(m-2)}

at m= 3 in PI

PI=\frac{4e^{3t}}{2}=2e^{3t}

so the complete solution is

CF+PI=c_1e^{2x}+c_2e^{x}+2e^{3t}
