A=17655+1230y, B=15900+1425y
We wish to know when A=B so:
15900+1425y=17655+1230y subtract 15900 from both sides
1425y=1230y+1755 subtract 1230y from both sides
195y=1755 divide both sides by 195
y=9
So in 9 years both cars would cost the same.
Answer:
Total profit = $59.10
Step-by-step explanation:
Total profit = Total selling price - total buying price
Total selling price = $75.50 + $83.60 = $159.10
Total buying price = 2 × $50 = $100
Hence total profit earned = $159.10 - $100 = $59.10
Graph of a negative parabola oriented about the y axis with y intercept at positive 6 : It's a function
graph of an absolute value function oriented about the y axis : it's a function called piecewise
graph of an ellipse with x intercepts negative 8 and positive 8 : it's not a function, since the vertical line intersects the ellipse in 2 different points
graph of a line with a positive slope and y intercept of negative 6: it's a linear function
A diagonal of a rectangle is 8cm and forms an angle measuring 30 with one side. Find the area of a rectangle
Let's first draw the picture. The diagonal of your rectangle will be a line that goes from the top left corner of your rectangle to the bottom right corner. This line is the hypotenuse of your RIGHT triangle. The problem tells us that the hypotenuse forms a 30 degree angle with on of the sides. We can pick either side, but I chose to pick the side that includes the left side of the rectangle. Now, we have a 30-60-90 right triangle. The base of the triangle is opposite the 30 degree angle, so it will equal x. The hypotenuse is 2x and the height is x√3.
SO, since we know the hypotenuse is 8cm, we know: 8=2x and x=4; x√3=4√3
The area of a rectangle is b*h, so we multiple 4√3*4 to give us 16√3
Hope that helps!
