Answer:
x = 2.
Step-by-step explanation:
If its a parallelogram then the diagonal will be bisected so:
4x + 7 = 10x - 5
7 + 5 = 10x - 4x
12 = 6x
x = 2.

A ball moves in a straight line has an acceleration of a(t) = 2t + 5. Find the position function of the ball if its initial velocity is -3 cm per second and it’s initial position is 12 cm.
Answers
Answer:
[tex]s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12[/tex]
Step-by-step explanation:
Relation between acceleration, velocity and position:
The velocity function is the integral of the acceleration function.
The position function is the integral of the velocity function.
Acceleration:
As given by the problem, the acceleration function is [tex]a(t) = 2t + 5[/tex]
Velocity:
[tex]v(t) = \int a(t) dt = \int (2t+5) dt = \frac{2t^2}{2} + 5t + K = t^2 + 5t + K[/tex]
In which K is the constant of integration, which is the initial velocity. So K = -3 and:
[tex]v(t) = t^2 + 5t - 3[/tex]
Position:
[tex]s(t) = \int v(t) dt = \int (t^2 + 5t - 3) = \frac{t^3}{3} + \frac{5t^2}{2} - 3t + K[/tex]
In which K, the constant of integration, is the initial position. Since it is 12:
[tex]s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12[/tex]

A telephone pole casts a shadow that is 12 feet long. At the same time, a man standing nearby who is 6 feet tall casts a shadow that is 2 feet 4 inches long. How tall is the
telephone pole to the nearest foot?
The telephone pole is feet tall
Answers
Answer:
31 feets
Step-by-step explanation:
Given that :
Telephone shadow Ts = 12 feets
Man's height, Mh= 6 feets
Man's shadow, Ms = 2 feets 4 inches
Height of telephone, Th =?
Recall :
1 foot = 12 inches
x foot = 4 inches
12x = 4
x = 4/12 = 1/3 inches
Hence, man's shadow = 2 1/3 feets =
Using cross multiplication :
Mh / Ms = Th / Ts
6 / 7/3 = Th / 12
6 / 2.33333 = Th / 12
12 * 6 = 2.33333 * Th
72 = 2.33333 Th
Th = 72 / 2.333333
Th = 30.85
Height of telephone pole = 31 feets
Which of these lines is perpendicular to the line 5y = -6x + 2?
Answers
Answer:6y= -5x + 3
Step-by-step explanation:
The product of the slope of the perpendicular lines is equal to a negative one. Then the equation of the perpendicular line is 6y = 5x.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The equation of the line is given below.
5y = -6x + 2
The slope of the equation is -6/5.
Then the equation of the line which is perpendicular to 5y = -6x + 2 is given as
y = mx + c
The product of the slope of the perpendicular lines is equal to a negative one.
The slope of the perpendicular line will be
(-6/5) m = -1
m = 5/6
Then the equation will be
y = (5/6)x + c
Let the equation is passing through the origin, then we have
6y = 5x

Cars enter a car wash at a mean rate of 3 cars per half an hour. What is the probability that, in any hour, at least 3 cars will enter the car wash
Answers
Answer:
0.938
Step-by-step explanation:
Using the poisson probability relation:
P(x = x) = (e^-λ * λ^x) ÷ x!
λ = 3 per half an hour = 6 cars per hour
P(x ≥ 3) = 1 - [p(x = 0) + p(x = 1). + p(x = 2)]
P(x ≥ 3) = (e^-6* (6^0 + 6^1 + 6^2/2!))
P(x ≥ 3) = 1 - (e^-6 * (1 + 6 + 18)
P(x ≥ 3) = 1 - (e^-6 * 25)
P(x ≥ 3) = 1 - (0.0024787 * 25)
P(x ≥ 3) = 1 - 0.0619688
P(x ≥ 3) = 0.9380311

A. 318 new, 12 used
B. 12 new, 18 used
C. 16 new, 8 used
D. 8 new, 16 used
(It's B, just took the test)
Answers
Answer:
b
Step-by-step explanation:
the following equations can be determined from the question
16n + 8o = 336 equation 1
n + o = 30 equation 2
where n = new books
o = old books
Multiply equation 2 by 8
8n + 8o = 240 equation 3
subtract equation 2 from 1
8n = 96
n = 12
substitute for n in equation 2
12 + o = 30
o = 18
