The power in watts,P, that is generated by a certain electric circuit depends on the current in amperes ,i, and can be modeled by the equation P=20(i-3)^2+180, Where i>3. Which of the following gives the value of i in terms of P?
i=3+2squareroot5(P-180)
i=3+1/2sq p-180/5
Answer:
i = {√(P-180)/20}+ 3
Step-by-step explanation:
Here, we simply need to make i the subject of the formula
that would be;
P -180 = 20(i-3)^2
Divide through by 20
(P-180)/20 = (i-3)^2
Find the square root of both sides
sqr (P-180)/20 = i-3
i = {√(P-180)/20}+ 3
Based on a survey, assume that 32% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that when six consumers are randomly selected, exactly three of them are comfortable with delivery by drones. Identify the values of n, x, p, and q.
Answer:
n = 6
x = 3
p = 0.32
q = 0.68
Step-by-step explanation:
Given:
32% are comfortable having drones deliver their purchases.
Suppose we are to find the probability that when 6 consumers are randomly selected, exactly 3 of them are comfortable with delivery by drones.
Required:
Find n, x, p, and q.
i) n represents the sample size. Here 6 consumers are selected randomly, therefore the sample size here is 6.
Thus, n = 6
ii) x represents the sample mean or number of successes. Since 3 consumers out of the selected 6 are comfortable with delivery by drones, the sample mean here is 3.
Thus, x = 3
iii) p represents population proportion or probability of success. Here population proportion(success probability) is 32% ≈ 0.32.
Thus, p = 0.32
iv) q represents probability of failure. To find probability of failure, use the formula:
1 - p
Thus,
1 - 0.32 = 0.68
q = 0.68

Raj’s bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. The table shows that the amount of water remaining in the bathtub, y, is a function of the time in minutes, x, that it has been draining. what is the range of this function
Answer:
raj’s bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. (given)
thus, rate of draining of water gallons per minute = -1.5
amount of water remaining in the bathtub = y,
the function of the time in minutes that it has been draining = x, .
at 0 minutes the amount of water is 40 gallons.
thus,the volume of water is 40 is decreasing at the rate of 1.5 gallons per minute
the given function is a linear function
y = 0
however, the volume of water can be 0 but cannot ever be negative.
thus, the range of y will be all real numbers such that 0≤y≤40

Find the point on the terminal side of θ = -3π/4 that has an x coordinate of -1. Show your work, please
Answer:
Step-by-step explanation:
[tex]-\frac{3\pi}{4}[/tex] is the same as -135°. Since positive angles are measured counterclockwise, and this one is negative, we are measured clockwise. Doing that puts us into the second quadrant where both x and y are negative. The terminal side of the angle is the side that is free to move and open and close the angles. The initial side is the one that is on the positive x-axis and does not move. We are looking for a point on the terminal side of that angle, which means we are looking for the (x, y) coordinate on that point where x = -1.
Now...between the negative x-axis and the terminal side of the angle is a 45°. That's what's important here. From the origin we move left along the negative x-axis to -1. From that point we can drop an altitude to meet the terminal side and have created a right triangle in the process. Where the altitude meets the terminal side is the point (-1, y) that we are looking for.
Now comes the point in your work where you need to remember the Pythagorean triple for a 45-45-90 triangle. On a unit circle, everything is based on 1 unit, and the side length across from a 45 degree angle is 1. In our case, because we are in the second quadrant, both the side lengths across from both of those angles will be 1 and they will both be negative. That means that the point on the terminal side of that angle is (-1, -1).
In the diagram, StartFraction V Z Over Y Z EndFraction = StartFraction W Z Over X Z EndFraction. Triangles V W Z and Y X Z are connected at point Z. To prove that △VWZ ~ △YXZ by the SAS similarity theorem, which other sides or angles should be used? WV and XY WV and ZY ∠VZW ≅ ∠YZX ∠VWZ ≅ ∠YXZ
Answer:
Option C.
Step-by-step explanation:
It is given that
[tex]\dfrac{VZ}{YZ}=\dfrac{WZ}{XZ}[/tex]
Triangles VWZ and YXZ are connected at point Z.
According to SAS similarity theorem, two triangles are similar if two corresponding sides are proportional and the angles between proportional sides are equal.
To prove that △VWZ ~ △YXZ by the SAS similarity theorem, we have two corresponding proportional sides nd we need to find the angle between proportional sides.
In △VWZ and △YXZ, VZ and YZ, WZ and XZ are corresponding angles which are proportional.
Angle between VZ and WZ is ∠VZW.
Angle between YZ and XZ is ∠YZX.
So, △VWZ ~ △YXZ by the SAS similarity theorem if ∠VZW ≅ ∠YZX.
Therefore, the correct option is C.

2х + 6 = 7x - 14
What’s the answer?
Answer:
x = 4
Step-by-step explanation:
2x + 6 = 7x - 14
2x - 7x = - 14 - 6
-5x = -20
x = 4
Answer:
[tex]\boxed{x=4}[/tex]
Step-by-step explanation:
=> 2x+6 = 7x-14
Subtracting 2x to both sides
=> 6 =7x-2x-14
=> 6 = 5x-14
Adding 14 to both sides
=> 6+14 = 5x
=> 20 = 5x
=> 5x = 20
Dividing both sides by 5
=> x = 20/5
=> x = 4

Answer:
The pyramid's height h = 12 ft
Step-by-step explanation:
Notice that the slant height of the pyramid forms a right angle triangle with the segment that joins the bottom end of the slant height with the center of the pyramid's base, and with the pyramid height (h).
The segment joining the slant height with the center of the pyramid's base is one half of the side of the base in length, so that it; 16 feet.
then we have a right angle triangle with hypotenuse given by the pyramid's slant height (20 ft), a leg given by 16 ft, and we need to find the length of the second leg (pyramid's height (h).so we use the Pythagorean theorem:
[tex]hyp^2=leg_1^2+leg_2^2\\(20\,ft)^2= (16\,ft)^2+h^2\\h^2=400\,ft^2-256\,ft^2\\h^2=144\,ft^2\\h=12 \,ft[/tex]

Which statistical tests should the researchers use to compare the mean pulse rates from each group
Answer:
One-way ANOVA test.
Step-by-step explanation:
In this case, the participants were randomly assigned to one of three groups:
Exercise Program AExercise Program BExercise Program CA z-test or a t-test is used when we need to test the significance of the difference between two group means.
A One-way ANOVA test is used to determine whether there is significant difference between the means for more than two groups.
Thus, a One-way ANOVA test can be used to compare the mean pulse rates from each group.
What is the equation for a straight line that would allow you to predict the value of Y from a given value of X. That is, calculate the value of "a" and the value of "b" and then substitute the 2 values into the generic equation (Y = a + bX) for a straight line. (Hint: calculate "b" first)
Answer:
[tex]m=-\frac{13}{20.8}=-0.625[/tex]
Nowe we can find the means for x and y like this:
[tex]\bar x= \frac{\sum x_i}{n}=\frac{16}{5}=3.2[/tex]
[tex]\bar y= \frac{\sum y_i}{n}=\frac{35}{5}=7[/tex]
And we can find the intercept using this:
[tex]b=\bar y -m \bar x=7-(-0.625*3.2)=9[/tex]
So the line would be given by:
[tex]y=-0.625 x +9[/tex]
Step-by-step explanation:
We have the following data:
X: 3,3,2,1,7
Y:6,7,8,9,5
We want to find an equationinf the following form:
[tex] y= bX +a[/tex]
[tex]a=m=\frac{S_{xy}}{S_{xx}}[/tex]
Where:
[tex]S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}[/tex]
[tex]S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}[/tex]
So we can find the sums like this:
[tex]\sum_{i=1}^n x_i = 3+3+2+1+7=16[/tex]
[tex]\sum_{i=1}^n y_i =6+7+8+9+5=35[/tex]
[tex]\sum_{i=1}^n x^2_i =72[/tex]
[tex]\sum_{i=1}^n y^2_i =255[/tex]
[tex]\sum_{i=1}^n x_i y_i =99[/tex]
With these we can find the sums:
[tex]S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}=72-\frac{16^2}{5}=20.8[/tex]
[tex]S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}=99-\frac{16*35}{5}=-13[/tex]
And the slope would be:
[tex]m=-\frac{13}{20.8}=-0.625[/tex]
Nowe we can find the means for x and y like this:
[tex]\bar x= \frac{\sum x_i}{n}=\frac{16}{5}=3.2[/tex]
[tex]\bar y= \frac{\sum y_i}{n}=\frac{35}{5}=7[/tex]
And we can find the intercept using this:
[tex]b=\bar y -m \bar x=7-(-0.625*3.2)=9[/tex]
So the line would be given by:
[tex]y=-0.625 x +9[/tex]
HELP ASAP PLEASE ------ for the function f(x)=x^2 what effect will multiplying f(x) b y 1/4 have on the graph
Answer:
Vertical Shrink of a factor of 1/4
Step-by-step explanation:
Since we are manipulating a in f(x) = a(bx - h)² + k, we are dealing with vertical stretch (x > 1) and vertical shrink (x < 1). Since 1/4 < 1, we have a vertical shrink of 1/4.
Answer: if you multiply the f(x) by 1/4 the graph seems to narrow, which is interpreted as a positive vertical shift . The y value (output) is 4 times greater
If you multiply the x² by 1/4, the graph seems to widen, which is interpreted as a negative vertical shift. The y value is less by a factor of 1/4
Step-by-step explanation: I am reading the question literally: multiplying f(x) by 1/4. (This may be dangerous as mathematicians have their own lingo, and some words have specialized meanings that English majors haven't learned!)
I understand that f(x) or any other function is the y-output. So in order to graph a function, it is legitimate to substitute "y" for f(x).
I am attaching a graph with the f(x)=x² in red f(x) = (1/4)x² in green and (1/4)f(x) = x² in blue.
As you can see, very different results: Substituting 2 for x
in red original 4 = 2²
in green f(x) = (1/4)(2²) . 1 = (1/4)(4)
in blue (1/4)f(x) = x² (1/4) 16 = (2²) =. This is probably not the intended result, but it is literally what happens if you multiply the left side! 16 is the output on the graph.
So, despite my efforts to make sense of this, I realize that this answer is mistaken, and I hope someone can clear up my confusion, please!
