Answer:
d. -4 <= x - 5
Step-by-step explanation:
I think youre asking about question 5.
First replace the x with the -2 in every problem.
Now solve:
a. 6 × -2 < 10
6 times -2 is -12, and -12 is less than -10, so that ones true and not the answer
b. -2 × -2 > -3
-2 times -2 is 4, and 4 is greater than -3, so that ones true and not the answer
c. -2/4 <= 0
-2 divided by 4 is -1/2, and -1/2 is less than 0. so that ones true and not the answer
So obviously the answers d, but we're gonna check anyway
d. -4 <= -2 - 5
-2 minus 5 is -7, and -7 is not less than -4, so its not true and the answer

The perimeter of a rectangle is 56 feet and
its area is 192 square feet. What are the
dimensions of the rectangle?
Answer:
Step-by-step explanation:
P = 2(L + W)
Area = L*W
Area = 192
(L + W)*2 = 56
L+W = 28
L = 28 - W
W*(28 - W) = 192
28W - w^2 = 92
-w^2 + 28w - 192 = 0
w^2 - 28w + 192 = 0
This factors into
(w - 12)(w - 16) = 0
w - 12 = 0
w = 12
L = 28 - 12 = 16
for each number x in a finite field there is a number y such x y=0 (in the finite field). true false
The answer is False. In a finite field, for each non-zero number x, there exists a multiplicative inverse y such that x*y = 1, not 0. The only number that would satisfy x*y = 0 in a finite field is when either x or y is 0.
True. In a finite field, every non-zero element has a multiplicative inverse, meaning that there exists a number y such that x*y = 1. Therefore, if we multiply both sides by 0, we get x*(y*0) = 0, which simplifies to x*0 = 0. Therefore, for each number x in a finite field, there is a number y such that x*y = 0.
Multiplying an even number equals dividing by its difference and vice versa. For example, dividing by 4/5 (or 0.8) will give the same result as dividing by 5/4 (or 1.25). That is, multiplying a number by its inverse gives the same number (because the product and difference of a number are 1.
The term reciprocal is used to describe two numbers whose product is 1, at least in the third edition of the Encyclopedia Britannica (1797); In his 1570 translation of Euclid's Elements, he mutually defined inversely proportional geometric quantities.
In the multiplicative inverse, the required product is usually removed and then understood by default (as opposed to the additive inverse). Different variables can mean different numbers and numbers. In these cases, it will appear as
ab ≠ ba; then "reverse" usually means that an element is both left and right reversed.

What is the total displacement of the car after 5 h? question 8 options: 0 km 15 km 20 km 40 km.
The total displacement of the car after 5hrs is 0km.
Displacement is a vector quantity that refers to the object's overall change in position.changing in final position from its initial positioncalculating the distance between an object's initial position and its final position.In physics terms, displacement is referred to as the variables. The displacement formula is as follows:s =sf– si
where, s = displacement.
In the given graph, there is the change in distance covered with the time that is:
after two hours car reaches 15 km away from the initial pointafter 4 hours it reaches 20 km away from the initial pointAfter 5 hours car returns back to the initial point.Thus, the displacement will be 0 km as the final point and initial point are the same.

Find the charge on the capacitor in an LRC-series circuit at t = 0.03 s when L = 0.05 h, R = 3.12, C = 0.008 f, E(t) = 0 V, 9(0) = 4 C, and i(0) = 0 A. (Round your answer to four decimal places.) 0.8630 хс Determine the first time at which the charge on the capacitor is equal to zero. (Round your answer to four decimal places).
At t = 0.03 s, the charge on the capacitor in the LRC-series circuit is 0.8630 C.
In an LRC-series circuit, the charge on the capacitor can be calculated using the formula Q(t) = Q(0) * e^(-t/(RC)), where Q(t) is the charge at time t, Q(0) is the initial charge on the capacitor, R is the resistance, C is the capacitance, and e is the base of the natural logarithm.
Given the values L = 0.05 H, R = 3.12 Ω, C = 0.008 F, E(t) = 0 V, Q(0) = 4 C, and i(0) = 0 A, we can substitute these values into the formula. Using the given time t = 0.03 s, we can calculate the charge on the capacitor.
Plugging in the values, we have Q(0.03) = 4 * e^(-0.03/(3.12*0.008)). Evaluating this expression gives us Q(0.03) ≈ 0.8630 C, rounded to four decimal places.

3. Prove that if an object is traveling at a constant speed, its velocity and acceleration vectors are orthogonal.
If an object is traveling at a constant speed, its velocity and acceleration vectors are orthogonal.
To prove that the velocity and acceleration vectors of an object traveling at a constant speed are orthogonal, we need to show that their dot product is zero. Let's consider a particle moving in a straight line.
The velocity vector, v, represents the rate of change of displacement with respect to time. Since the object is moving at a constant speed, the magnitude of the velocity vector remains constant. Therefore, the derivative of the velocity vector with respect to time is zero, resulting in a constant velocity vector.
The acceleration vector, a, represents the rate of change of velocity with respect to time. Since the speed is constant, the direction of the velocity vector remains constant, and there is no change in direction. As a result, the acceleration vector is perpendicular (orthogonal) to the velocity vector.
We can express the dot product of the velocity and acceleration vectors as v ⋅ a = |v| |a| cos θ, where θ is the angle between the vectors. Since the speed is constant, |v| is constant. If the angle between the velocity and acceleration vectors is 90 degrees (cos θ = 0), the dot product will be zero.The velocity and acceleration vectors are orthogonal when the object is traveling at a constant speed.

mass of water vapor (g) / mass of dry air (kg)
is the humidity measure of....
-the mixing ratio.
-relative humidity.
-vapor pressure.
-absolute humidity.
The mass of water vapor (g) / mass of dry air (kg) is the humidity measure of the mixing ratio
The mixing ratio is defined as the mass of water vapor in grams divided by the mass of dry air in kilograms in a mixture of air and water vapor. It is a useful parameter for meteorologists and atmospheric scientists to describe the amount of water vapor in the atmosphere, particularly in the upper atmosphere where the relative humidity may be very low.
Relative humidity is the ratio of the partial pressure of water vapor in the air to the equilibrium vapor pressure at a given temperature and pressure, expressed as a percentage. Vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Absolute humidity is the mass of water vapor per unit volume of moist air.

Given:

A vertex of a triangle has the coordinates (-3, 8).
The triangle undergoes a dilation about the origin of scale factor 0.5.
What are the coordinates of the above vertex after the dilation?
When a point on a triangle is dilated, the coordinate of the vertex changes
The coordinate of the vertex after the dilation is (-1.5,4)
How to determine the coordinate after dilationThe given parameters are:
(x,y) = (-3,8)
k = 0.5
To calculate the coordinate of the vertex after the dilation, we make use of:
(x,y)' = k * (x,y)
So, we have:
(x,y)' = 0.5 * (-3,8)
Evaluate the product
(x,y)' = (-1.5,4)
Hence, the coordinate of the vertex after the dilation is (-1.5,4)
