Which is the slope for the equation that is perpendicular to y=-4x+3
Answers
Answer:
\(\frac{1}{4}\)
Step-by-step explanation:
The equation for a line is y=mx + b where m represents the slope
If a line is perpendicular to another line, it's slope is the negative reciprocal of the other line's slope.
The reciprocal of -4 is \(-\frac{1}{4}\)
And the negative of that would be \(\frac{1}{4}\)

sin 56°45' is closest to
A 0.8334
B 0.8363
C 0.7071
Answers
The value of sin is 56°45' which is the very closest to 0.8363. Option B is correct.
For finding the value of sin 56°45', we use trigonometric tables or a calculator for computing the answer
Transfigure the given angle to decimal form, and we get:
56°45' = \(56+\frac{45}{60}\)= 56.75°
Then by using a calculator or trigonometric tables for computing, we find the value of sin 56.75 degrees. So, the closest value to sin 56.75° is approximately 0.8363.
So, the correct answer is 0.8363.

Which functions could be represented by the graph? Check all that apply.
f(x) = | x + 0.14|
f(x) = |x| + 1.3
f(x) = |x – 7|
f(x) = |x + 12|
f(x) = |x| – 17
f(x) = |x – 23|
Answers
The possible functions are:
\(f(x) = |x + 0.14|\) and \(f(x) = |x + 12|\)
The parent function of an absolute value function is:
\(f(x) = |x|\)
From the diagram (see attachment), we can see that the function is shifted to the right by few units.
The rule of this translation is:
\((x,y) \to (x + b,y)\)
Where b represents the number of units.
So, we have:
\(f(x) = |x + b|\)
From the list of given options, the possible functions are:
\(f(x) = |x + 0.14|\) and \(f(x) = |x + 12|\)

Why is water a necessary element for our bodies to function properly?Maintain a regular body temperature. Joints should be lubricated and cushioned. Safeguard your spinal cord and other delicate structures. Wastes can be eliminated by urine, sweat, and bowel motions. Dehydration can also cause a decrease in strength and stamina. It is the most common cause of heat exhaustion. At this point, you should be able to reverse dehydration by consuming extra fluids. Chronic dehydration might impair your kidney function and raise your risk of kidney stones. Water also helps with normal bowel function, muscular performance, and clean, young skin. Failure to drink enough water, on the other hand, can result in dehydration and negative symptoms such as weariness, headache, reduced immunity, and dry skin.

A triangle with given vertices have (-1,5/2) as circumcenter, (1,40 as orthocenter and [-1/3, 3] as centroid.
What is right angle triangle?A right triangle is one that has an interior angle of 90 degrees. The hypotenuse, which is also the side of the right triangle that faces the right angle, is its longest side. The height and base make up the two arms of the right angle.
What is circumcenter of a triangle?The intersection of the perpendicular bisectors of a triangle's sides is known as the circumcenter of that particular triangle. In other terms, the circumcenter is the point at which the bisector of a triangle's sides coincides.
That's a right triangle, essentially half a rectangle. The common midpoint of the diagonals of a rectangle is equidistant from the four corners. So the midpoint of the hypotenuse is the circumcenter of a right triangle.
That's 1/2*(−3+1,4+1)=(−1,5/2)
To calculate centeroid:
ler (a,b)=(1,1)
(c,d)=(1,4)
(e,f)=(-3,4)
Now
Centeroid= [a+c+e/3, b+d+f/3]
=[1+1-3/3 , 1+4+4/3]
=[-1/3, 3]

We have that the sides of a right triangle receive different names depending on the angle we are going to analyze.
The opposite side of the right triangle is the hypotenuse:
And depending on the angle we are going to analyze, one side is that opposite to it and the other side is the adjacent:
Finding the missing sideWe know by the Pythagorean Theorem that:
opposite² + adjacent² = hypotenuse²
In this case
hypotenuse = 20
adjacent = 16

Then
opposite² + adjacent² = hypotenuse²

For calculation purposes, use 5 decimal places as displayed in the factor table provided, e.g. 1.25124.)
Answers
Net present value is a measure of profitability. The NPV of an investment is the net cash inflow received over the project's life, less the initial cash outflow, adjusted for the time value of money.
A higher NPV means the project is more lucrative. The profitability index measures the benefit-cost ratio of a project and is calculated by dividing the present value of future cash flows by the initial cash outflow. A profitability index greater than one indicates that the project will be profitable, whereas a profitability index less than one indicates that the project will not be profitable.

P(T) = 7/12 (probability of threaded widget)

In developing patient appointment schedules , a medical centre wants to estimate the mean time that a staff member spends with each patient. How large a sample should be taken if the desired margin of error is 2 minutes at a 95 per cent level of confidence? How large a sample should be taken for a 99 per cent level of confidence ? Use a planning value for the population standard deviation of 8 minutes.
Answers
A. A sample size of 62 should be taken for a 95% level of confidence.
B. The sample size of 107 should be taken for a 99% level of confidence.
a. To estimate the sample size needed to estimate the mean time a staff member spends with each patient, we can use the formula for sample size calculation:
n = (Z^2 * σ^2) / E^2
Where:
n = required sample size
Z = Z-score corresponding to the desired level of confidence
σ = population standard deviation
E = desired margin of error
For a 95% level of confidence:
Z = 1.96 (corresponding to a 95% confidence level)
E = 2 minutes
σ = 8 minutes (population standard deviation)
Substituting these values into the formula:
n = (1.96^2 * 8^2) / 2^2
n = (3.8416 * 64) / 4
n = 245.9904 / 4
n ≈ 61.4976
Since we can't have a fraction of a sample, we round up the sample size to the nearest whole number. Therefore, a sample size of 62 should be taken for a 95% level of confidence.
b. For a 99% level of confidence:
Z = 2.58 (corresponding to a 99% confidence level)
E = 2 minutes
σ = 8 minutes (population standard deviation)
Substituting these values into the formula:
n = (2.58^2 * 8^2) / 2^2
n = (6.6564 * 64) / 4
n = 426.0096 / 4
n ≈ 106.5024
Rounding up the sample size to the nearest whole number, a sample size of 107 should be taken for a 99% level of confidence.

the minimum requirements for a class i aluminum main lightning conductor are ? strand size, 95 pounds/1,000 feet weight per length, and a cross-sectional area of 98,600 circular mils.
Answers
The minimum requirements for a class i aluminum main lightning conductor are a strand size, 95 pounds/1,000 feet weight per length, and a cross-sectional area of 98,600 circular mils.
These requirements are set by industry standards and regulations to ensure the safety and effectiveness of the lightning protection system. The strand size refers to the diameter of the individual wires that make up the conductor, which must meet a minimum size to withstand the forces of a lightning strike. The weight per length is a measure of the conductor's strength and durability, with a higher weight indicating a more robust design. Finally, the cross-sectional area is the total area of the conductor's circular shape, which impacts its ability to conduct electrical current and dissipate the energy from a lightning strike.
Overall, meeting these minimum requirements is essential for ensuring that a lightning protection system is capable of effectively capturing and directing the energy from a lightning strike to the ground, protecting the building and its occupants from potential harm.
