Answer:

  q - p

Step-by-step explanation:

For complementary angles B and C, ...

  cos(C) = sin(B) = p

  sin(C) = cos(B) = q

Then the difference is ...

  sin(C) -cos(C) = q - p

Can u guys PLEASE answer the depreciation question ASAP. THIS IS URGENT!

Answer: the value of the car after 7 years is $11220

Step-by-step explanation:

The formula for determining depreciation is expressed as

A = P(1 - r)^t

Where

A represents the final value of the car after t years.

P represents the present value of the car.

r represents the rate of depreciation

t represents the number of years.

From the information given

P = 35000

r = 15% = 15/100 = 0.15

t = 7 years

Therefore,

A = 35000(1 - 0.15)^7

A = 35000(0.85)^7

A = 11220.198

Rounding up yo the nearest dollar, it becomes $11220

Answer:

\huge \boxed{ \boxed{z = 3}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • equation
  • PEMDAS
<h3>let's solve:</h3>
  1. \sf simplify \: substraction :  \\  \frac{3}{ \frac{z - 2}{z} }  = 3z
  2. \sf simplify \: complex \: fractio n : \\  \frac{3z}{z - 2}  = 3z
  3. \sf cross \: multiplication :  \\ 3z = 3z(z - 2)
  4. \sf divide \: both \: sides \: by \:  3z :  \\  \frac{3z}{3z} =   \frac{3z(z - 2)}{3z} \\ 1 = z - 2
  5. \sf add \: 2 \: to \: bot h  \: sides :  \\  z - 2 +  2 = 1 + 2 \\ \therefore \: z = 3

The formula s= sqrt SA/6
ikadub [295]
For this case we have the following equation:
 s = root (S.A / 6)
 Substituting values we have:
 For S.A = 180:
 s = root (180/6)
 s = root (30)
 For S.A = 120:
 s = root (120/6)
 s = root (20)
 s = root (4 * 5)
 s = 2 * root (5)
 Subtracting both values we have:
 root (30) - 2 * root (5)
 Answer:
 
root (30) - 2 * root (5)
 
option 2
