Properties of Circles - Tangent (HELP!!)

In the diagram, H and K are the centres of two circles whose radii are 3 cm and 5 cm respectively. The two circles touch each other at C and TN is a common tangent to the circles at A and B. Find the

Math: Absolute Value Help

Pretend the parenthesis are absolute value symbols. (x+7) + 10 = 6 Is it a solution why or why not?-|x+7| + 10 = 6 Subtract 10 from both sides: |x+7| = -4 No. Absolute values are always positive.

Can someone please explain this to me? Simplify 8x + 3x[10 - 4(3 - x)]

;_____; It is so freaking simple but for some reason, I keep getting confused anyway... -.--8x + 3x[10 - 4(3 - x)] 8x + 3x[10 - 12 +4x] 8x + 3x [ -2 + 4x] 8x - 6x + 12x^2 2x + 12x^2 12x^2 + 2x

Find an equation for the linear function which has slope -10 and x -intercept -9

Im not sure how to even start to find the linear function from these numbers. Is there a formula to follow to find this?-If it hits x at -9 (where y is zero) then its going to hit y at -90 and in poin

Partial Differential Equation

Solve the partial differential equation d^2u/(dxdy) = 0 for u(x,y)-Integrate both sides with respect to x: ∂u/∂y = F(y) for some arbitrary function F Integrate both sides with respect to y: u(x, y) =

Find an equation for the linear function which has f( 0.2 ) = 0.6 and f( 0.6 ) = -0.5

Can someone tell me how to work this? Im not quite sure where to even start.-you have two points(0.2, 0.6) and (0.6, -0.5) find your slope:difference in ys divided by difference in xs. Then use this

Inverse Laplace Transformation

I have the following equation: y+6y+8y=2. I am supposed to use laplace transformation and inverse laplace transformation to solve it. For la place transformation I got Y(s) = 2/s(s^2+6s+8). Im confuse

What is 2 + 4/11 also can you please explain how you got the answer step by step explanation

Algebra1-2 + 4/11 get like denominators so 22/11 + 4/11 26/11-Take 2 and find the common denominator between the two. Think of 2 as a fraction, 2/1. The least common denominator is 22, so multiply 2/

Help in mathematics, urgent. . .

If 5+3+2 = 151012, 9+2+4= 183662, 8+6+3 = 482466, 5+4+5= 202504 then what will be the answerof 7+2+5? Only 2% people are able to solvethis aptitude question-Its 143542 The key is, let the given number

2 Geometry questions. 10 points (Triangles)

1. The measures of the sides of an equilateral triangle are represented by x + 12, 3x - 8, and 2x + 2. What is the measure of each side of the triangle? 2. The measures of the sides of an isosceles t

Can anyone figure out 5 - 3/-6

5 - 3/-6 = 5 - (3/-6) = 5 - (-2) = 5 + 2 = 7 Yeah sorry about that, I guess I had a brain fart there. It should be: = 5 - (3/-6) = 5 - (-1/2) = 5 + (1/2) = (10/2) + (1/2) = 11/2-3/6 is not 2... 5-(-

Can you show me the steps for this Trigonometry question

Hi, Find the central angle to the nearest tenth of a degree that intercepts an arc of length 1 foot on a circle of radius 8 feet. I know the formula but still Im a bit confused with this part. Thanks
