Since it's just a line, make an x y table of values, plot the points, and connect them with a line. Or you could use transformation rules by moving around the graph of y=x.

We know the formula for the Volume of a Right Circular Cone is given by V=(1/3)*pi*r^2*h V=140 in^3 The height of the cone = diameter of the base. The diameter = 2 times the radius, so h = 2r The formula for Volume can now be written as V=(1/3)*pi*r^2*(2r...

The answer would then be C. 160 cm^3 The Volume of a cone is given by V=(1/3)*pi*r^2*h We know V= 540 cm^3 and that r=15 cm and can plug into the equation to find h. I am going to leave the units off, but you should include it in your work. 540=(1/3)*pi*(...

You did the problem correctly. I am not sure how exactly you entered the numbers into the computer for pi, but it looks like with an answer of 24,523.71 the computer used an approzimation for pi based on the fraction 22/7. 22/7 = 3.142857.... If you plug...

BAD is correct. It is 84. If you would like to use algebra, do the following: x:= Unit Digit Number y:= Tens Digit Number The units digit is 4 less than the tens digit number so We know that x=y-4 The tens digit is twice the units digit so we know that y=...

BTW Cassie, please please always remember that pi is simply a circle's circumference divided by it's diameter. For every circle, no matter the size... This is why it shows up in so many formulas for circles, cylinders, cones, etc.

If X^2-5 is the denom, then the domain would be all X such that the denom does not equal 0. So find when x^2-5=0 x=sqrt(5) (Both positive and negative) So the domain is all real numbers, such that X does not equal +- sqrt (5)

Yes, you are correct. Key word is circular, so we are talking about a circle. pi = circumference of a circle / diameter --> pi = C / d Solve for C C = pi*d = (3.14) *(10 ft) = 31.4 ft, assuming the approximation of 3.14 for pi.

No...Use c^2=a^2+b^2. Use a= 24, b= 32 and c= 42 (the longest side). Take a^2 + b^2 and see if it eqauls c^2 If it does, it is a right angle. If it does not, it is not a right triange. In this case, it does not, so it is not a right triangle.

Keep in mind it does not have to be in ratio of 3:4:5 to be a right triangle, it has to make the equation c^2=a^2+b^2 true. Another common right triangle is 5,12,13.

Hi. I don't understand why you multiply by 50*pi/180. The 50 degrees is the difference in the longitude, but why isn't that divided by 360? Why the pi/180? If someone could clear that up I would appreciate it.
