at a given instant the legs of a right triangle are 5cm and 12 cm long. if the short leg is increasing at the rate of 1cm/sec and the long leg is decreasing at the rate of 2cm/sce, how fast is the area changing

Algebra Word Problem
COULD SOMEONE PLEASE HELP ME WITH THIS !!!!!!!!!! The base of a triangle is 3cm greater than the height. The area is 44cm^2. Find the height and length of the base. The height of the triangle is_______ cm The base of the traingle is_______cm

The area is the area of the base triangle + the area of the three sides. You did not say if all three sides (or indeed all 4 sides) are the same, so that is about all I can say.

The base of a triangle is 8cm greater than the height. The area is 42cm^2. Find the height and length of the base.
Wednesday, January 14, 2009 at 11:33am by Kim
Area of triangle = 1/2(height x base) The problem states that base is 8 cm greater than the height; therefore, base-8 = height. A = 1/2(b*h) 42 = 1/2(b*[b-8]) 84=(b^2-8b) rearrange to b^2 - 8b -84 factor to (b+8)(b-14) Therefore, b = -8 cm which makes no sense and b = +14 cm ...

join the centre to each vertex, that would give you 8 isosceles congruent triangles. work on one of those. the central angle is 45 degrees making each of the angles at the vertex 67.5 degrees. You can find the height by tan 37.5 = height/3.5 height = 8.44975 so the area of one...

The second sentence is not needed. Draw the triangle. Compute the side lengths s1=AB= sqrt ((bx-ax)^2+(by-ay)^2 ) = sqrt ( 13^2 + (-14)^2 )= sqrt (169+256)=20.6 and do that for all sides. Then knowing the sides, calculate the perimeter, divide by 2. Let that be p. Area=sqrt (p...

Your question makes no sense to me. The law of cosines is this a^2=b^2+c^2 - 2bc * CosA I have no idea what 1/2 ab SinC is , unless it is the area formula for a triangle. You need to be more specific.

I assume the acceptable values are in the triangle. so for the bottom line: y=mx+b the two points are 2,1 and 11,3 y=2/9 x+ b ( m= (y1-y2)/(x1-x2) then to solve for b 3=2/9 *11 + b b=3-22/9=5/9 so the solution area here, is all above the line, or y>2x/9 + 5/9 Now consider ...

The prisms's hexagonal base area is six times the area of an equilateral triangle with side length 10 cm. Double that for the combined areas of top and bottom. There are also six rectangular sides, each with area 18 x 10 cm

1.find the value of X. Simply answers that are radicals. hypotenuse is 10 sides (legs) are 6 and x. the total base is 12. 2. Find the area of the figure. Round decimal answers to the nearest tenth. sides of the triangle is 8 cm and total base is 7 cm

The sum of the perimeters of an equliateral triangle and square is 10. Find the dimensions of the triangle and square that produce a minimum total area.

That is the Pythagorean theorem, which states that: in any right triangle, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares whose sides are the two legs.

Parametric curves and area
1.The curve of x=49-t^2 and y=t^3-1*t makes a loop which lies along the x-axis. What is the total area inside the loop? 2.Find the area of the region enclosed by the parametric equation: x=t^3-7*t and y=4*t^2.

If the triangle is equalaterial, then QT is also six, so the area of the square is 36.
