Peter inherits 15.000 dollars and place money with a bank. The interest rate are 3 percent. How many money will he get after 1ye
NeTakaya
The simplest form of an interest equation is A = P(1+rt)

where A = the total amount of money at the end, P = the principal (or amount of money you started with), r = the rate in percent, and t = the time in years.

In this case, P = 15000, r = 0.03 (because 3% in decimal form is 0.03), and t = 1:

A=P(1+rt)\\A=15000(1+0.03*1)\\A=15000(1+0.03)\\A=15000(1.03)\\A=15450

So, after 1 year he will get $15450 back, making him $450 more.

In circle P, if the radius is 3 cm, what is the length of arc AD?
umka21 [38]

Hello there.

We have for a circle that:

\ell=\alpha r

Where:

\ell is the measure of the arc

\alpha is the measure of the angle (radians)

r is the radius of the circle


In our case, we have \alpha = 120^\circ = \dfrac{120}{180}\pi = \frac23\pi ~rad

We have r = 3 cm, then:

\ell = (\frac23\pi )(3\ cm)\\ \\ \boxed{\ell = 2\pi~cm}

Step-by-step explanation:

Data

function   f(x) = x² + 2x - 8

-See the graph below

1) x-intercepts

We observe in the graph that there are no x-intercepts.

2) y-intercepts

We observe in the graph that the y-intercept is (0, 8). Point A

3) axis of symmetry

The axis of symmetry is the line that divides the parabola into two equal parts. This line is x = -1 (blue line)

4) The vertex is the lowest point of the parabola, this point is (-1, 7)
