What is the volume of the doorstep below

kati45 [8]

Answer:

$V=63\ in^3$

Step-by-step explanation:

-The total volume will be the sum of the volumes of the triangular section plus the rectangular section.

#Volume triangular section:

$V=Base\ Area\times length\\\\Base\ Area=\frac{1}{2}bh\\\\=\frac{1}{2}\times 3\times 3\\\\=4.5\\\\\therefore V_t=4.5\times 6\\\\=27\ in^3$

#Volume rectangular section:

$V=lwh\\\\=3\times 2\times 6\\\\=36\ in^3\\\\\therefore V_r=36\ in^3$

#Total volume of the doorstep:

$V=V_t+V_r\\\\=27+36\\\\=63\ in^3$

Hence, the doorstep's volume is $63\ in^3$

You want to buy a new sports car from roy's cars for $51,800. the contract is in the form of a 48-month annuity due at an apr of

qwelly [4]

The present value of an annuity is given by

$PV= P\left(\frac{1-\left(1+ \frac{r}{t}\right)^{-nt} }{ \frac{r}{t} } \right)$

where: PV is the current value of the annuity, P is the periodic payment, r is the apr, t is the number of compounding in one year and n is the number of years.

Thus, given that PV = $51,800; r = 7.8% = 0.078; t = 12; n = 4.

$51,800= P\left(\frac{1-\left(1+ \frac{0.078}{12}\right)^{-4\times12} }{ \frac{0.078}{12} } \right) \\ \\ =P\left(\frac{1-(1+ 0.0065)^{-48} }{ 0.0065 } \right)=P\left(\frac{1-(1.0065)^{-48} }{ 0.0065 } \right) \\ \\ =P\left(\frac{1-0.7327}{ 0.0065 } \right)=P\left(\frac{0.2673}{ 0.0065 } \right)=41.12P \\ \\ \Rightarrow P= \frac{51,800}{41.12} =\$1,259.73$

Therefore, the <span>monthly payment is $1,259.73</span>

Answer:

You would not subtract 3...
