Answer:
Step-by-step explanation:
<h2>
<em><u>First</u></em><em><u> </u></em><em><u>case</u></em><em><u>:</u></em></h2>
Sides of a square = 3 cm
Therefore, area of the square = <em>side × side</em>
= 3cm × 3cm
<h2>
<em><u>Second</u></em><em><u> </u></em><em><u>c</u></em><em><u>ase</u></em><em><u>:</u></em></h2>
Radius of the circle = 4cm
Therefore, area of the circle
<h2><em><u>Last</u></em><em><u> </u></em><em><u>case</u></em><em><u>:</u></em></h2>
Area of the shaded region
= <em>Area</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>circle</em><em> </em><em>-</em><em> </em><em>Area</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>square</em><em> </em>
Answer:
B
Step-by-step explanation:
Because there are 2 different y values for the x value of 5. All x values can only have 1 y value.
For B, there are y points on the x value of 5, so this fails the vertical line test, and is therefore not a function
Step-by-step explanation:
5ˣ⁻² = 6
Take log of both sides.
log 5ˣ⁻² = log 6
Use log exponent property.
(x − 2) log 5 = log 6
Solve for x.
x − 2 = log 6 / log 5
x = 2 + (log 6 / log 5)
x = 3.1133
Answer: 455 mph
Step-by-step explanation:
if train one is traveling one way at 60mph, then you have to multiply that by 3.5 to see how far it traveled in that amount of time.
60 x 3.5 = 210
then, you have to multiply 3.5 by 70mph, to see how far the second train has traveled in that amount of time
70 x 3.5 = 245
finally, since both trains are moving in opposite directions, you have to add up the distances together to get the final difference
210 + 245 = 455
