$275*.15(15%)=41.25 (this is the amount of the discount)
$275-$41.25=$233.75 (cost of jacket after discount)
$233.75* .0725=$16.946(round to $16.95, this is the amount of the sales tax).
If you want to know the total cost after tax just add $16.95 to the discounted price of $233.75. The price you pay for the jacket is $250.70.
The number 1.41421356.... is a(n) rational number because its a repeating decimal that can be written as a fraction.
You can plug in any values that make the equation true, and then plot the ordered pair.
I chose (3,1) and (6,4)
1 = 3-2
4=6-2
Plot the two ordered pairs and connect the dots to draw a line.
Answer:
A non-calculus solution follows afterward.
For a calculus solution, the gradient is the first derivative with the point put in.
y = -x²+3x
dy/dx or y’ = -2x +3 is the gradient at any point.
but the tangent is at x = 2 so put it in
y’ = -(2*2)+3 = -1 is the gradient of the tangent at point (2,2)
Non-calculus solution:
y = -x²+3x 1️⃣but slope of tangent m = (y-2)/(x-2)2️⃣
put 1️⃣ into 2️⃣ and rearrange ⟹ mx-2m+x²-3x+2 = 0
or x²+(m-3)x+2–2m =0
but for a tangent the discriminant b²-ac = 0
(m-3)²-4*1*(2–2m) = 0
m²+2m+1 = 0
(m+1)(m+1) = 0
m = -1 is the is the gradient of the tangent at point (2,2)
Step-by-step explanation:
The total volume of this squared-base pyramid based on the information provided is 2666 micrometers.
<h3>How to calculate the volume of the pyramid?</h3>
The general formula to calculate the volume of a squared-based pyramid is:
<h3>What is the volume of the model?</h3>
Base area: 20 x 20 = 400
400 micrometers x 20/ 3 = 2666 micrometers.
