The sum of two numbers is 30. Their difference is 6. What are the numbers?
baherus [9]

Answer:

Find out the numbers .

To prove

Let us assume that one number be x.

Let us assume that second number be y.

As given

The sum of two numbers is 30.

Than the equation becomes

x + y = 30

Their difference is 6.

x - y = 6

Thus two equation are .

x + y = 30 and x - y = 6

Subtracted  x - y = 6 from x + y = 30

x - x + y - (-y) = 30 - 6

y + y  = 24

2y = 24

y = \frac{24}{2}

y = 12

Put in the x - y = 6

x - 12 = 6

x = 6 + 12

x = 18

Therefore the two numbers are 12 and 18 .

In 2012 your car was worth $10,000. In 2014 your car was worth $8,800. Suppose the value of your car decreased at a constant rat
Sonbull [250]

Answer:

g(t) = 10000(0.938)^t

Step-by-step explanation:

Given data:

car worth is $10,000 in 2012

car worth is $8000 in 2014

let linear function is given as

P(t) = at + b

which denote the value of car in year t

take t =0 for year 2012

at t =0, 10,000 = 0 + b

we get b = 10,000

take t =2 for year 2014

at t =2, P(2) = 2a + b

8800 = 2a + 10,000

a = - 600

Thus the price of car at year t after 2012 is given as p(t) = -600t + 10000

let the exponential function p(t)  =ab^2 where t denote t = 0 at 2012

putting t = 0 P(0) = 10,000 we get 10,000 = ab^0

a = 10,000

putting t = 2 p = 8800

8800 =ab^2

b^2 = \frac{8800}{10000}

b = 0.938

g(t) = 10000(0.938)^t

Can I get help on this question? Please explain the process of how to solve it too.
gizmo_the_mogwai [7]

Answer:

x = 13

y = 18.38

Step-by-step explanation:

tan 45 = x/13       (tangent = opposite / adjacent)

1 = x/13

multiply both sides by 13

x = 13

cos 45 = 13/y       (cosine = adjacent / hypotenuse

0.7071 = 13/y

multiply both side by y

0.7071y = 13

divide both side by 0.7071

y = 18.38
