Answer:
w = (4 - 3C)/(C - 1).
Step-by-step explanation:
C=(4+w)/(w+3)
Multiply both sides of the formula by w+3:-
C(w + 3) = 4 + w
Cw + 3C = 4 + w
Cw - w = 4 - 3C

In a 10-year period, Bakersfield, CA population grew from 558,000 to 718,000. What is the percentage of increase? (Round to the nearest tenth of a percent)
The percent increase to the nearest tenth is 22.2%
Calculating percent increasePercent increase is the percent it takes from a value to change from its initial value
Given the following
Initial value = 558,000
Final value = 718,000.
Determine the percent increase
% increase = (718,000-558000)/718,000 * 100
% increase = 160000/718000 * 100
% increase = 22.2%

Step-by-step explanation:
f(x)=x^4+12x^3+30x^2−12x+70
The remainder theorem says that f(a) is the value of f(x) when f(x) is divided by (x - a).
So when a = -5 f(a) will be 5.

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. The sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively.

How are the graphs of the reciprocal functions related to their corresponding original functions? What happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? Describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions.

What are trigonometric functions?It should be noted that the trigonometric functions are the real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
There are six functions of an angle. They are sine (sin), cosine (cos), tangent (tan), cotangent, secant, and cosecant (csc).
It should be noted that all the y-coordinates of a reciprocal function will be the reciprocals of the y-coordinates of the original function. Then, the graph of a reciprocal function has a vertical asymptote at each zero of the original function. For example, y=arcsinx reflects against y=sinx.

How do you find the interior angle of a triangle given the external angle of 125°
Answer:
<x = 55 degrees
<y = 55 degrees
<z = 70 degrees
Step-by-step explanation:
The 125 degree angle and x are supplementary since they form a straight line, which means that their degrees add up to 180. To find x, the interior angle, we must subtract 125 from 180.
180 - 125 = 55
Angle x is 55 degrees. Since the sides opposite x and y are marked with lines, they are congruent, and since the sides are congruent, the angles must be, too. So, y is also 55 degrees.
Finally, the angles in any triangle add up to 180 degrees. To find z, we must subtract the values of x and y from 180.
180 - 55 - 55 = 70, so z is 70 degrees.
Brainliest, please :)
❄Hi there,
the external angle & the interior angle form a linear pair, which means, if you add these angles together, you'll arrive at 180°.
Using this knowledge let's set up an equation and find x:
[tex]\triangleright \ \sf{125+x=180}[/tex]. We let x be the desired angle.
[tex]\triangleright \ \sf{x=180-125=55}[/tex]
So the interior angle is [tex]\angle\sf{55}\textdegree[/tex].

A family is having a pool built in their backyard. If their yard is rectangular and measures 10x by 10x and the pool is circular with a radius of 2x how much of the yard will be left over after the pool is built
Answer:
[tex]100x^2-4\pi x^2[/tex]
Also can be said as:
[tex]4x^2(25-\pi )[/tex]
Step-by-step explanation:
The scenario:The question is asking you, "how much is left over."
In this scenario, you're going to have to subtract the area of the pool (P) from the total area of the backyard (B), which will leave you with the remaining area of the backyard (x).
This means your equation to solve this question is:
[tex]x=B-P[/tex]
Step 1:The value of B is the area of the backyard.
We are told that the backyard is a rectangular shape. So, we can use the formula of finding the area of a rectangle.
The formula is [tex]B=L*W[/tex], where L is the length and W is the width.
Both the length and width are 10x, so we must plug that into this equation.
We end up getting:
[tex]B=10x*10x[/tex]
Which can be simplified to:
[tex]B=100x^2[/tex]
Step 2:The value of P is the area of the pool.
The pool is a circular shape. So, to get the area of it, we must use the formula of finding the area of a circle.
The formula is [tex]P=\pi r^2[/tex], where r is the radius.
Plugging in the radius of 2x, we get:
[tex]P=\pi (2x)^2[/tex]
By solving this out, we end up with:
[tex]P=4\pi x^2[/tex]
Step 3:From the scenario, we have the equation:
[tex]x=B-P[/tex]
And from steps 1 and 2, we have the values:
[tex]B=100x^2[/tex] and [tex]P=4\pi x^2[/tex]
Now we just plug those values in to get:
[tex]x=100x^2-4\pi x^2[/tex]
And finally, the amount of the backyard remaining is:
[tex]100x^2-4\pi x^2[/tex]
Different format:This answer may be simplified to:
[tex]4x^2(25-\pi )[/tex]

If the sample size of population is 24 then the number of degrees of freedom for reading the t value is 23 which is option c.
Given sample size of 24,mean 23.
We have to determine the number of degrees of freedom which will be used to find the critical values of t.
Degree of freedom is the number of values in the final calculation of a statistic that are free to vary means that can change their values in the formula of calculating t.

Because the sample statistic centers around a different value than the population parameter, the sample mean absolute deviation is a biased estimator of the population mean absolute deviation.
Reason Behind a Biased Estimator
The expected value (average) of all the sample absolute deviations must match the population absolute deviation in order for the absolute deviation to function as an unbiased estimator. It does not, however, which makes the values of sample mean absolute deviation behave as a biased estimator.

What are transformations?When a function is transformed, the graph's curve either "moves to the left/right/up/down," "expands or compresses," or "reflects."
Function transformations are highly useful for graphing functions without having to start from scratch because they allow you to move, extend, compress, or reflect the curve.
