Answer: 7.2%
Step-by-step explanation:
First find the difference between the amounts.
7,400, 000 - 6, 900,000 = 500, 000
Now divide the obtain number by the original number which is 6,900,000
500, 000/ 6,900,000 = 0.07246
Multiply 0.07246 by 100 to convert it to a percent.
0.07246 = 7.2463..%
Round it to the nearest tenth of a percent.
7.2463.. rounded to the nearest tenth is 7.2%

Answer:
Expression for area = 3x² - 15x - 42
Step-by-step explanation:
Given that:
Length of rectangle desktop = 3(x+2) = 3x+6 units
Width of rectangle desktop = x - 7
Area of rectangle desktop = Length * Width
Area of desktop = (3x+6)(x-7)
Area = 3x(x-7) +6(x-7)
Area = 3x² - 21x + 6x - 42
Area = 3x² - 15x - 42
Hence,
Expression for area = 3x² - 15x - 42
Answer:
Alternate exterior angles
Step-by-step explanation:
Alternate exterior angles are angles that are formed outside two parallel lines that cuts through a transversal line. these angles are formed on the opposite side of the transversal line ( alternate side).
Also Alternate exterior angles are congruent in nature are they are not adjacent angles as well
Answer: x(t) = 5cm*cos(t*pi/2s)
Step-by-step explanation:
This is a sinusoidal equation, so we can write this as:
x(t) = A*cos(c*t + p) + B
where B is the axis around the movement, as the resting position is x = 0, we have B = 0
so x(t) = A*cos(c*t + p)
A is the amplitude of the oscilation, c is the frequency and p is a phase.
We know that when t = 0s, we have x(2s) = 5cm
if this is the maximum displacement, then knowing that the maximum of the cosine is cos(0) = 1
then we must have that p = 0
x(0s) = A*cos(0) = 5cm
then we have A = 5cm
Now, when t = 2s, we have:
x(2s) = 5cm*cos(2s*c) = -5cm
then 2s*c is the minimum of the cos(x) function, this is:
cos(pi) = -1
then 2s*c = pi
c = pi/2s.
then our function is:
x(t) = 5cm*cos(t*pi/2s)
