A shopkeeper marks:
$200 * 1.4 = $280
With a discount of 25%:
$280 * 0.75 = $210
216 I think because 3 times negative 2 is -6 the -6^3=6*6*6=216
Answer:
dV/dt = 3×10^2 × 0.5 = 150 in^3/sec
the volume of the cube is increasing at 150in^3/sec
Step-by-step explanation:
Volume V = length l^3
V = x^3
Differentiating both sides;
dV/dt = 3x^2 dv/dt
Given;
x = 10 in
dx/dt = 0.5 in/sec
dV/dt = 3×10^2 × 0.5 = 150 in^3/sec
the volume of the cube is increasing at 150in^3/sec
Answer:
(17, -13) (17, 8) --> In this problem, we use the y2-y1 over x2 - x1 formula.
Step-by-step explanation:
Step 1: Plug In--> <u>8-(-13)</u>
17 - 17
Step 2: Simplify: <u>21</u>
0
Answer: <em><u>Undefined. Vertical line on graph. </u></em>
Let's assume that you are to graph the inequality.
1. Graph -3x + 4y = 12. Note that the x-intercept is (-4,0) and the y-intercept is (0,3). Use a dashed line, not a solid line, due to the ">" sign.
2. Choose a test point (e. g., (0,1) ) and subst. these coordinates into -3x + 4y = 12. Is the equation then true or false? If true, shade the area (on one side of -3x + 4y = 12 or the other) in which the test point (0,1) lies. If false, shade the other side of -3x + 4y = 12.
