Bob Rohrman is offering a 2017 Toyota Camry for $29,000. If you have a 7% down payment and are able to borrow the rest at a 2.99

Yakvenalex [24]

Monthly installment payment is $597 .Total payments is $28,649

Step-by-step explanation:

Down payment = $29,000×7 ÷100= $2,030

Loan amount = $29,000 - 2,030 = $26,970

Interest rate = 2.99%

Repayment period = 48 months (4 years)

simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods.

= 26,970 (1+0.0299) × 4) +p =$28,648.51

$= 26,970 (1+0.0299) × 4) +p =$28,648.51$

Monthly payment = $596.84 (or) $597 (rounded off)

$Monthly payment = $596.84 (or) $597 (rounded off)$

Total payments is $28,649

Write an equation for a circle with a diameter that has endpoints at (-10, 1) and (-8, 5). Round to the nearest tenth if necessa

kherson [118]

Answer:

The equation is (x+9)^2 + (y-3)^2 = 5

Step-by-step explanation:

The standard form for the equation of a circle is:

(x−h)^2+(y−k)^2=r2

The center of the circle is the midpoint of the diameter.

So the midpoint of the diameter at (-10, 1) and (-8, 5) can be determined as:

(-10 +(-8))/2 , (1+5)/2

= -10-8/2, 1+5/2

= -18/2 , 6/2

= -9 , 3

Thus(-9,3) is the center of the circle.

Now we will use the distance formula to find the radius of the circle.

r^2=(-10-(-9))^2 + (1-3)^2

r^2=(-10+9)^2 +(-2)^2

r^2=(-1)^2 + (-2)^2

r^2=1 + 4

r^2= 5

Take square root at both sides.

√r^2= √5

r=√5

Now put the values in the 1st equation.

(x−h)^2+(y−k)^2=r2

where h = -9, k =3 and r = √5

(x-(-9))^2 + (y-3)^2= (√5)^2

(x+9)^2 + (y-3)^2 = 5

Thus the equation is (x+9)^2 + (y-3)^2 = 5 ....
