The corresponding sides of two similar triangles are . The corresponding angles of two similar triangles are .
madreJ [45]
If the corresponding sides of two similar triangles have congruent angles than the sides correspond to each other 
in triangle abc
and triangle def 
ab:de
bc:ef
ca:fd
so they correspond in ratio but are not necessarily congruent
if in the similar triangles the sides are equal than the angles will correspond in ratio to add up to 180 degrees
so if triangle abc≈ triangle def
then
∠abc:∠def
∠bca:∠efd
∠cab:∠def

mario is taking a $2,900, 2-year loan with an APR of 5.44%. what is the montly payment for this loan? round to the nearest cent
sasho [114]

Answer:

The monthly payment for this loan is $127.80

Step-by-step explanation:

The formula of the monthly payment is

M.P=\frac{P(\frac{r}{n})}{1-(1+\frac{r}{n})^{-nt}}

  • P is the initial amount of the loan
  • r is the rate in decimal
  • n is the period of the time
  • t is the time of the loan

∵ Mario is taking a $2,900, 2-year loan with an APR of 5.44%

∴ P = 2,900

∴ t = 2

∵ ART means annual percent rate

∴ r = 5.44% = 5.44 ÷ 100 = 0.0544

∴ n = 12

→ Substitute all these values in the formula above

∵ M.P = \frac{2,900(\frac{0.0544}{12})}{1-(1+\frac{0.0544}{12})^{-(12)(2)}}

→ use your calculator to find the answer

∴ M.P = 127.7992528

→ Round it to the nearest cent ⇒ 2d.p

∴ M.P = 127.80

∴ The monthly payment for this loan is $127.80

A and b are monomials where a = 125 and b = 27p12. what is the factored form of a – b?
torisob [31]

The factored form of a - b is \left(5-3 p^{4}\right)\left(25+15 p^{4}+9 p^{8}\right).

<h3>What is monomial factorization ?</h3>

A monomial is an expression that is the product of constant and non-negative integer powers of x, like 3x^{2}..

A monomial is expressed as a product of two or more other monomials when it is factored.

Here,

a = 125

$b=27 p^{12}$

To find: a - b

a - b = 125 - 27 p^{12}$

a - b =  5^{3}-\left(3 p^{4}\right)^{3}$

We know that,

$x^{3}-y^{3}=(x-y)\left(x^{2}+x y+y^{2}\right)$

Finding the factored form of a - b using this method:

$a - b=\left(5-3 p^{4}\right)\left(5^{2}+5\left(3 p^{4}\right)+\left(3 p^{4}\right)^{2}\right)$

$a-b=\left(5-3 p^{4}\right)\left(25+15 p^{4}+9 p^{8}\right)$

So, factored form of a - b is $\left(5-3 p^{4}\right)\left(25+15 p^{4}+9 p^{8}\right)$.
