Answer:

167º

Step-by-step explanation:

The interior angles in an n-gon add up to 180(n-2). So, the interior angles in a 28-gon add up to 180(28-2)=180(26)=4680. To find out the measure of one angle divide 4680 by 29. 4680/28 is about 167.

Answer:

$C=10000(0.852)^t$

Step-by-step explanation:

Let the exponential function be,

$C=a(b)^t$

Here, C = cost of the car

t = Duration or period in years

From the given table,

Two points representing cost of the car and time are (10000, 0) and (8520, 1),

For (10000, 0),

$10000=a(b)^0$

a = 10000

For (8520, 1)

8520 = $10000(b)^1$

$b=\frac{8520}{10000}$

b = 0.8520

Therefore, exponential equation will be,

$C=10000(0.852)^t$

If sin ⁡x=7/25, and 0 < x < π/2, what is cos⁡(x−3π/2)?

Likurg_2 [28]

Answer:

$Cos(x-\frac{3\pi}{2})=-\frac{7}{25}$

Step-by-step explanation:

Remember that $cos(x-y)=cos(x)cos(y)+sin(x)sin(y)$

Then,

$cos(x-\frac{3\pi}{2})=cos(x)cos(\frac{3\pi}{2})+sin(x)sin(\frac{3\pi}{2})\\$

But $cos(\frac{3\pi}{2})=0$ and $sin(x)=\frac{7}{25}$

Then

$cos(x-\frac{3\pi}{2})=cos(x)*0+\frac{7}{25}*sin(\frac{3\pi}{2})\\=\frac{7}{25}*(-1)=\frac{-7}{25}$

Construct an equation using the given information

elena-s [515]

Answer:

So, equation using the given information :

5 is subtracted from a number the result is the same as the number tripled will be: x-5=3x

Step-by-step explanation:

We need to make an equation of: 5 is subtracted from a number the result is the same as the number tripled.

Let, the number be x

5 is subtracted from a number will be: x-5

The number tripled will be: 3*x

The required equation will be:

x-5=3x

So, equation using the given information :

5 is subtracted from a number the result is the same as the number tripled will be: x-5=3x
