Answer:
10 + 5i & 10 - 5i
Step-by-step explanation:
10 + 5i is still just 10 + 5i because we treat i like it's x.
Complex conjugate if I remember correctly is like a + or - form, so I believe 10 - 5i is correct?
Hope this helped.
Answer:
The sign of acceleration is positive.
Step-by-step explanation:
Consider the provided information.
It is given that A student drops a penny from the top of a tower and decides that she will establish a coordinate system in which the direction of the penny's motion is positive.
Here the direction of the velocity is positive, and the velocity is increasing.
Acceleration is defined as the rate at which an object changes its velocity.
Since velocity is positive therefore the acceleration is also positive.
Hence, the sign of acceleration is positive.
The total cost is $41.85
Amount Saved = 45 x 7 / 100
Amount Saved = 315 / 100
Amount Saved = $3.15 (answer).
In other words, a 7% discount for a item with original price of $45 is equal to $3.15 (Amount Saved).
Note that to find the amount saved, just multiply it by the percentage and divide by 100.

Answer:
Step-by-step explanation:
Equation for an exponential function is given as following:
Where <em>b</em> is the common ratio and
<em>c</em> is the horizontal asymptote (y value)
<em>a</em> is the coefficient of exponential term of 
are the points on the function.
Here, we are given that:
Common ratio, b = 2
Horizontal asymptote at y, c = 4
So, the equation becomes (let us put the values of <em>b</em> and <em>c</em>):
We need the value of <em>a. </em>Let us put value of (x,y) as (2,10).
So, the final equation of the exponential function is:
