Mathematics
1 answer:
inessss [21]3 years ago
5 0

negative multiplied by positives = negative numbers

3 x 5 = -15

negative multiplied by a negative = a positive number

-3 x -2y = +6y

so combine both gets -15 +6y

or a better way to write it is 6y-15

The cash price of the car includes the amount of the loan plus the amount of the down payment
Cash price=the loan of the car+down payment

First find the amount of the loan by using the formula of the present value of an annuity ordinary which is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv the amount of the loan ?
PMT payment per month 355
R interest rate 0.071
K compounded monthly 12
N time 5years
Pv=355×((1−(1+0.071÷12)^(−12
×5))÷(0.071÷12))
=17,885.56

Cash price=17,885.56+2,500

The hours of daylight, y, in Utica in days x from January 1, 2013 can be modeled by the equation y = 2.89sin(0.0145x-1.40) + 10.
Pie

Answer:

9.3 hours

Step-by-step explanation:

Given

y = 2.89\sin(0.0145x-1.40) + 10.99.

Required

Hours of sunlight on Feb 21, 2013

First, calculate the number of days from Jan 1, 2013 to Feb 21, 2013

days = 52

So:

x = 52

So, we have:

y = 2.89\sin(0.0145x-1.40) + 10.99.

y = 2.89\sin(0.0145*52-1.40) + 10.99.

y = 2.89\sin(0.754-1.40) + 10.99.

y = 2.89\sin(-0.646) + 10.99.

y = 2.89*-0.6020 + 10.99.

y = -1.740 + 10.99.

y = 9.25

<em></em>y = 9.3<em> --- approximated</em>

Do 2(x, y) → (3,5).<br> The point (x,y) is
Elan Coil [88]

Answer:

(1.5, 2.5)

Step-by-step explanation:

(x,y) is being multiplied by 2 to get (3,5). We need to divide it by 2 to find x and y.

3/2= 1.5

5/2=2.5

Thus, the answer is (1.5, 2.5). Hope this helped!
