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 length of the sofa on the plans is ____"(Simplify your answer. Type an integer, fraction, or mixed number.)
Answers
Given:
\(\frac{1}{6}^{\doubleprime}\text{ on a plan for 1 foot }\)The length of the sofa is 6'3''.
We need to convert the foot into inches.
\(1\text{ foot = 12 inches.}\)\(1^{\prime}=12^{\doubleprime}\)Multiply both sides by 6, we get
\(1\times6^{\prime}=12\times6^{\doubleprime}\)\(6^{\prime}=72^{\doubleprime}\)The length of the sofa is

Polynomials
What are monomials?
Monomials are expressions with one term.
What are binomials?
Binomials are expressions with two terms.
What are trinomials?
Trinomials are expressions with three terms.
What are polynomials?
Polynomials are expressions with four or more terms.
How many terms does 9x have?
It has only one term. So it's a monomial.
\(\therefore\) it is a monomial
for each number x in a finite field there is a number y such x y=0 (in the finite field). true false
Answers
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.

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?
Answers
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)

mass of water vapor (g) / mass of dry air (kg)
is the humidity measure of....
-the mixing ratio.
-relative humidity.
-vapor pressure.
-absolute humidity.
Answers
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.

3. Prove that if an object is traveling at a constant speed, its velocity and acceleration vectors are orthogonal.
Answers
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.

The perimeter of a rectangle is 56 feet and
its area is 192 square feet. What are the
dimensions of the rectangle?
Answers
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

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).
Answers
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.
