If f(x) = x2 – 3x – 40 intersects the x-axis at points A and B, what is the sum of A and B?
Eduardwww [97]

Answer:

3

Step-by-step explanation:

Intersections on the x axis occur when y = 0. f(x) is another term for y, so set f(x) equal to zero and solve for the two possible x's.

0 = x^2 - 3x - 40

0 = (x-8)(x+5)

By solving for x, you get 8 and -5. 8 and -5 added together will equal 3.

Derive the equation of motion of the spring-mass system given below. Please show and MARK your derivation step by step. Missing
Arte-miy333 [17]

Answer:

Ö + θ ( (k/m) + (g/l)) = 0

Step-by-step explanation:

Use the FBD attached:

Apply Newtons 2 nd Law in tangential direction:

Sum ( Ft ) = m*a

Sum of all tangential forces is:

m*g*sin(θ) + k*l*sin(θ)*cos(θ) = - m*l*Ö

Using small angle approximations:

sin (θ) = θ

cos (θ) = 1

Ö = angular acceleration.

m*g*θ + k*l*θ = -m*l*Ö

Ö + θ ( (k/m) + (g/l)) = 0

On the pie chart below, which “slice” red presents 30% of the budget?
salantis [7]

B. 2


1 is way too big, 4 is way too small, 3 is clearly less than a fourth of the pie chart, so it must be 2.
