Determine the domain function fx 8x-4x squared-5x-36?
f(x) = 8x - 4x2 - 5x - 36 = -4x2 + 3x - 36 The domain for f(x) can be the whole of the Complex field or any subset.
What is the volume of a cuboid when its height is in the ratio of 15 to 8 to its width and has a length of 22 cm with a surface area of 2506 square cm showing work?
Suppose the height is 15x cm. Then the width is 8x cm. Then the surface area is 2*(15x*8x + 8x*22 + 22*15x) cm2 Therefore 2*(15x*8x + 8x*22 + 22*15x) = 2506 or 15x*8x + 8x*22 + 22*15x = 1253 120x2 + 506x - 1253 = 0 so that x = -529/30 or 13/4 But x cannot be negative so x = 1.75. Therefore, volume = (15*1.75)*(8*1.75)*22 = 8085 cm3
What is the value of x id the acute angle of a right triangle measure 8x and 12x?
It is: x = 4.5 and so the acute angles are 36 degrees and 54 degrees
What is the vertex of the graph y-2x2 8x-3?
y=-2x^2+8x+3
What is the slope of a line whose equation is 12 equals 4y-8x?
4y-8x = 12 4y = 8x+12 y = 2x+3 So the slope is 2 and the y intercept is 3
A triangle has an area of 36 square feet a base of 8x feet and a height of 4 feet what is the value of x?
Area_triangle = base x height x 1/2 ⇒ 36 = (8x) x 4 x 1/2 ⇒ 8x = 18 ⇒ x = 21/4 (= 2.25)
What is 8x-36 equal?
8x-36 equal = -28
What is the square root of 8x?
The square root of 8x can be simplified as √8x = √(4*2x) = 2√2x. This is because we can break down 8 into 4 and 2, and since the square root of 4 is 2, we can pull it out of the square root. Therefore, the simplified form of the square root of 8x is 2√2x.
What is X if -8x plus 4 equals 36?
To solve for x in the equation -8x + 4 = 36, you first need to isolate the variable x. Start by subtracting 4 from both sides of the equation to get -8x = 32. Then, divide both sides by -8 to find x. Therefore, x = -4.
What is the greatest common factor of 8x and 12xx square?
The GCF of 8x and 12x2 is 4x.
What is the square root of 10X multiplied by the square root of 8X?
√(10x) * √(8x) = √(80x²)√(80x²) = √(16x²) * √(5) = 4x*√(5)■
The length of a rectangle is 8 feet longer than its width which has the same dimension as the side of a square If the area of the rectangle is equal to 160 square feet more than the area of the squa?
length = 56 with = 48Improved Answer:Presumably your question is about finding the dimensions of a rectangle?If so then let the length be (x+8) the width be x and the square be x2:(x+8)*x = x2+160 square feetx2+8x = x2+160x2-x2+8x = 1608x = 160x = 20Therefore: length = 28 feet and width = 20 feetCheck: 28*20 = 400+160 = 560 square feet
Determine the domain function fx 8x-4x squared-5x-36?
f(x) = 8x - 4x2 - 5x - 36 = -4x2 + 3x - 36 The domain for f(x) can be the whole of the Complex field or any subset.
How do you figure out 5x plus 49 equals 8x plus 13?
5x+49 = 8x+13 49-13 = 8x-5x 36 = 3x x = 12
What is the solution to 5x-4 plus 3x equals 36?
5x - 4 + 3x = 36 Simplify: 8x - 4 = 36 Add 4 to both sides: 8x = 40 Divide both sides by 8: x = 5
-8 -8x-6 -6x-22?
It can be simplified to: -14x-36
What are the solutions to the equation below (4x plus 36)(8x-40)0?
Assuming you mean:(4x+36)(8x-40) = 0 then you can use the property that a product can only be zero if one of its factors is zero. In other words, you can change this to: 4x + 36 = 0 OR 8x - 40 = 0 Solve each of the individual solutions; their solutions are also solutions to the original equation.
