Actually I think it should be three. Two points to the side of the main point and one straight across.

4, is this correct?

Homework Statement A given point P is seven units from a given straight line. The number of points that are 3 units from the line and also 10 units from point P is: 1, 2, 3, or 4? The Attempt at a Solution Not sure how to approach this problem.

[b]1.) If (-4,8) is the image under the composite transformation Th,3 x T-2,k(-3,0), what are the coordinates of the image of (2,-1) under the same composite transformation? The Attempt at a Solution I'm lost on this one.

Homework Statement A square pyramid has a slant height of 25 m and a lateral area of 350 m2. Which is closest to the volume of the pyramid? Homework Equations A = 2sb+b^2 V = SQRT(2)/6*b^3 The Attempt at a Solution 350 = 2 (25) b + 0 -> b = 7m (B^2 is 0 since it is lateral area only) V =...

So the regular cone equation can be used even though the cone is abnormal?

The units would be m^3 (r*r*h)

Homework Statement Find the volume, see attachment Homework Equations I can't find the proper equation for this cone. The Attempt at a Solution he triangle is a 3, 4, 5 triangle. Is the typical cone equation of 1/3*PI*r^2*h used or a different equation?

70 = .5 (40+x) x = 100 Angle 1 = .5(100+40) Angle 1 = 70 However this answer is not an option. Where is my mistake?

Homework Statement See the attachment The Attempt at a Solution Is the answer simply 70-40=30?

Homework Statement 0 to infinity sum of 6/(4n-1)-6/(4n+3) Determine if the series is convergent or divergent. The Attempt at a Solution I know it is convergent by I cannot determine why.

Does the positive and negative parts cancel out if it is symmetric?

The problem wanted the function evaluated from -14 to 14. Does it make a difference if it is definitive or not? Is there a trick if it is definitive?

Homework Statement Find the integral f(x) = x^3 sqrt(x^2 + x^8 + 8) cox(x) dx The Attempt at a Solution I need help starting. It appears to be either integration by parts and/or substituion.

f(x) = x^2-1 f'(1) = 2(1) = 2 f(x) = k(x-1) f'(1) = k = 2 Therefore k=2 and is differentiable at this point now, correct?
