<h3>
Answer:</h3>
The value of k is 7
<h3>
Step-by-step explanation:</h3>
<em>1. We know f of x is going to be are starting line because it is listed in the equation first.</em>
<em>2. Both f of x and g of x have y intercepts</em>
<em>3. From f of x, count up until you reach g</em>
<em>4. The answer is 7, since you vertically shifted up 7 units</em>
Answer:
A = √29
Step-by-step explanation:
The short of it is that ...
A² = 2² + 5² = 29
A = √29
_____
<u>Amplitude</u>
If you expand the second form using the sum-of-angles formula, you get ...
Asin(ωt +φ) = Asin(ωt)cos(φ) +Acos(ωt)sin(φ)
Comparing this to the first form, you find ...
c₂ = 2 = Acos(φ)
c₁ = 5 = Asin(φ)
The Pythagorean identity can be invoked to simplify the sum of squares:
(Asin(φ))² + (Acos(φ))² = A²(sin(φ)² +cos(φ)²) = A²·1 = A²
In terms of c₁ and c₂, this is ...
(c₁)² +(c₂)² = A²
A = √((c₁)² +(c₂)²) . . . . . . . formula for amplitude
_____
<u>Phase Shift</u>
We know that tan(φ) = sin(φ)/cos(φ) = (Asin(φ))/(Acos(φ)) = 5/2, so ...
φ = arctan(c₁/c₂) . . . . . . . formula for phase shift*
φ = arctan(5/2) ≈ 1.19029 radians
___
* remember that c₁ is the coefficient of the cosine term, and c₂ is the coefficient of the sine term.

Answer:
Selling price of the laptop is $600.
Step-by-step explanation:
Let the sale price of the laptop = $x
Regular price of the laptop = $750
Discount on each computer = 20%
Selling price of the laptop 'x' = 750 - (20% of 750)
= 750 - 
= 750 - 150
= $600
Therefore, selling price of the laptop is $600.
