In the year 2003, a person bought a new car for $17500. For each consecutive year after that, the value of the car depreciated b
grandymaker [24]

Answer:

$12320

Step-by-step explanation:

Given data

Cost of car= $17500

rate of depreciation= 11%

duration= 2003 - 2006= 3 years

Let us apply the compound interest formula

A= P(1-r)^t

Note the negative sign(this is because of the depreciation)

A=17500(1-0.11)^3

A= 17500(0.89)^3

A=  17500*0.704

A= $12320

Hence the value of the car is $12320

Can someone explain this plz and make sure u round to the nearest tenth
bonufazy [111]

Step-by-step explanation:

According to figure,Taking angle 49° as reference angle,we have

b=26

h=x=?

Now,

\cos49  =  \frac{b}{h}  \\  \cos49   =  \frac{26}{x}  \\ 0.66 =  \frac{26}{x}  \\ 0.66x = 26 \\x =  \frac{26}{0.66}  \\ x = 39.39 \\ x = 39.4

Anyone know this ?? i need it. PLS SHOW WORK AND I'LL GIVE U BRAINLIEST AND 15 POINTS
olya-2409 [2.1K]

Answer:

60 degrees

Step-by-step explanation:

EF and DC have lines through them indicating that they are equal in length, telling us that the figure is an isosceles trapezoid. Congruent base angles are a property of isosceles trapezoids, like isosceles triangles. This means that the base angles C and F will have the same measure. The measure of angle F is 60 degrees, therefore the measure of angle C will also be 60 degrees.

hope this helps :)
