Hi!
I’d use Pythagora’s theorem here. If PR is 6, PQ is also 6. PQO is a right angle.

OQ^2=6.8^2 - 6^2
OQ^2=46.24 - 36
OQ^2=10.24
OQ= sqrt 10.24
OQ=3.2

ipn [44]

Answer:

1) C(0) = 9

2) C(50) =41.5

3) C(100) =74

Step-by-step explanation:

Given : A certain economy's consumption function is given by the equation C(x) = 0.65x + 9

where, C(x) is the personal consumption expenditure in billions of dollars, and x is the disposable personal income in billions of dollars.

To find :

1) C(0)

Put x=0 in the given equation,

C(0) = 0.65(0)+ 9

C(0) = 9

2) C(50)

Put x=50 in the given equation,

C(50) = 0.65(50)+ 9

C(50) =32.5+9

C(50) =41.5

3) C(100)

Put x=100 in the given equation,

C(100) = 0.65(100)+ 9

C(100) =65+9

C(100) =74

Art [367]

your question might be incomplete..

Answer/Step-by-step explanation:

Whether you're paying cash, leasing, or financing a car, your upper spending limit really shouldn't be a penny more than 35% of your gross annual income. For Example: $36,000 a year, the car price shouldn't exceed $12,600. Make $60,000, and the car price should fall below $21,000.

Hence, $11,656 x 35% =4079.60

Answer = 4079.6
