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 square root of 10X multiplied by the square root of 8X?
√(10x) * √(8x) = √(80x²)√(80x²) = √(16x²) * √(5) = 4x*√(5)■
What is the greatest common factor of 8x and 12xx square?
The GCF of 8x and 12x2 is 4x.
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.
