The center of a hyperbola is (-5,8). The length of the conjugate axis is 6 units, and the length of the transverse axis is 14 un

serious [3.7K]

Answer:

$(\frac{x+5}{3}) ^{2}+ (\frac{y-8}{7} )^{2} =1$

Step-by-step explanation:

IMPORTANT FORMULA: the standard equation of a hyperbola whose transverse axis is parallel to the y axis is:

$(\frac{x-h}{a}) ^{2}+ (\frac{y-k}{b} )^{2} =1$

where, (h,k) : center of the hyperbola

a : semi conjugate axis [ length of conjugate axis/2]

b: semi transverse axis [ length of transverse axis/2]

so, here a=3, b=7, [h,k]=[-5,8]

by substituting these values in the above given formula,

the equation of the hyperbola in standard form is :

$(\frac{x-(-5)}{3}) ^{2}+ (\frac{y-8}{7} )^{2} =1$

$(\frac{x+5}{3}) ^{2}+ (\frac{y-8}{7} )^{2} =1$

Find the amount financed and the finance charge in dollars for the following problem. choose the correct answers. josh hayes pur

melisa1 [442]

$350 * 30/100 = $ 105 which is down payment.
$350 - $105 = $245 which is left.
But he will pay $24.50 * 12 = $294 instead.
$294 - $245 = $49

He will pay $49 more.

He paid $105 as down payment and will pay $294 more with 12 months.

Total will be $105 + $294 = $399
