The solutions to the radical expression √3x-5= x-8 are x = 1.146 and x = 7.854

From the question, we have the following parameters that can be used in our computation:

√3x-5= x-8

Add 5 to both sides

So, we have

√3x= x - 3

Square both sides

So, we have

3x = x² - 6x + 9

So, we have

x² - 9x + 9 = 0

When solved, we have

x = 1.146 and x = 7.854

Answer:

Step-by-step explanation:

You want to identify a pair of supplementary angles, and a pair of vertical angles in the given figure.

Two angles are supplementary if they total 180°. This will be the case for any linear pair of angles. A linear pair of angles combines to form a straight line.

Supplementary angle pairs in the figure are ...

  (1, 2), (1, 3), (2, 4), (3, 4), (5, 6), (5, 7), (6, 8), (7, 8)

Two angles are vertical angles if they are formed by two intersecting lines and if their shared vertex is the point where the lines cross. The angles do not share a side, but have sides formed from opposite rays.

A pair of crossing lines forms two sets of vertical angles.

Vertical angle pairs in the figure are ...

  (1, 4), (2, 3), (5, 8), (6, 7)

Your answer will be a pair of angles from the first list, and a pair of angles from the second list. The highlighted pairs are the ones we list at the top of the answer.

Additional comment

Angles may be supplementary in a variety of other contexts. Adjacent angles in a parallelogram are supplementary, as are opposite angles in a quadrilateral inscribed in a circle. When parallel lines are crossed by a transversal, consecutive interior angles are supplementary, as are consecutive exterior angles. (There are no parallel lines in the given figure for this problem.)

The solutions of the equation in the interval [0, 27) are: θ = π/3, 2π/3.

An equation is a mathematical statement that shows that two expressions are equal. It typically consists of variables, constants, and mathematical operators.

Starting with the given equation:

3cot²θ - 1 = 0

Add 1 to both sides:

3cot²θ = 1

Divide both sides by 3:

cot²θ = 1/3

Taking the square root of both sides:

cotθ = ± √(1/3)

Since cotθ = cosθ/sinθ, we can write:

cosθ/sinθ = ± √(1/3)

Multiplying both sides by sinθ:

cosθ = ± √(1/3)sinθ

Squaring both sides:

cos²θ = (1/3)sin²θ

Using the identity sin²θ + cos²θ = 1, we get:

sin²θ + (1/3)sin²θ = 1

Simplifying:

(4/3)sin²θ = 1

Dividing by 4/3:

sin²θ = 3/4

Taking the square root of both sides:

sinθ = ± √(3)/2

We know that θ is in the interval [0, 27). Therefore, the possible solutions are:

θ = π/3 or θ = 2π/3

However, we need to check if these solutions are in the given interval.

For θ = π/3, we have:

0 ≤ π/3 < 27

Therefore, π/3 is a valid solution.

For θ = 2π/3, we have:

0 ≤ 2π/3 < 27

Therefore, 2π/3 is also a valid solution.

Thus, the solutions of the equation in the interval [0, 27) are:

θ = π/3, 2π/3

Answer & Step-by-step explanation:

In hypothesis testing, the claim being made is called the alternative hypothesis. The null hypothesis is the opposing statement, and it is presumed to be true until sufficient evidence suggests otherwise. The wording of the claim must be specific and precise, and one must clearly state the population, the parameter of interest, and the direction of the hypothesis test (i.e., one-tailed or two-tailed).

For example, a well-worded alternative hypothesis might be "The new teaching method will result in a higher mean test score for students than the traditional teaching method." In this case, the null hypothesis would be "The new teaching method will not result in a higher mean test score for students than the traditional teaching method."

An incorrectly worded claim might be "The new teaching method is better than the traditional teaching method." This claim is too vague because it does not specify in what way the new method is better, nor does it give a direction for the hypothesis test.

In summary, when conducting a hypothesis test to support a claim regarding the mean test score under a new teaching method, the wording of the claim must be specific and precise, and the claim will become the alternative hypothesis.

Answer:

3r + 2b = 600 ---(1)

r + b = 225 ---(2)

We can solve this system of equations using substitution or elimination method.

Using substitution method, we can solve equation (2) for "r" in terms of "b":

r = 225 - b

Substituting this expression for "r" into equation (1), we get:

3(225 - b) + 2b = 600

Simplifying and solving for "b", we get:

675 - 3b + 2b = 600

-b = -75

b = $75

Therefore, the cost of one bag is $75.

Step-by-step explanation:

for the first table to find the equation of its line you need to find the gradient(m). to do that you take 2 points then subtract the first y from the second y. so 12-9=3 then do the same with the x so 5-2=3 then divide the first by the second and 3÷3=1 so the gradient(m) is 1. so the equation is in the form y=mx+c and since we know m is 1 the equation will be y=x+c. to find c we take a point on the line and replace the numbers so 9=2+c must be true and for it to be true c must be 7. so the equation of the line is y=x+7. also pls mark as brainliest answer

Angle sum property of triangle:

             Sum of all the three angles of the triangle is 180°.

   50 + 2x + 3x - 10 = 180°

We may infer from the facts provided that Jaeger the goat will be confined to a 10- by-16-meter rectangular shelter by means of a 15-meter chain. All of the grass along the chain may be consumed by Jaeger. At three separate points in the shed, we are instructed to locate the patch of grass that Jaeger can eat.

Let's consider the three different locations as follows:

Attach the chain to a corner of the shed.

Jaeger can only eat as much grass as is contained inside a quarter-circle with a radius of 15 meters (the length of the chain) if the chain is fastened to a shed corner. This quarter-circle's area is:

Area = (1/4) x π x (15 meters)²

Area = 176.71 square meters (approx)

Affix the chain to the middle of one of the shed's longer sides.

This semicircle's area is:

b. The teacher will need to spend at most $49.92 on batteries for calculators over the year.

What is minimum average day?

a. The margin of error of ‡9% means that we can be 95% confident that the true average number of days the batteries will last is within 9% of the sample average. To find the minimum average number of days a teacher can expect to have the batteries last in her classroom, we subtract the margin of error from the sample average:

Minimum average = 101 - (0.09)(101) = 92.09 days (rounded to two decimal places)

Therefore, the teacher can expect the batteries to last at least 92.09 days on average.

What is spend ?

b. The total number of batteries required for the 24 TI-84 calculators is:

24 calculators x 4 batteries per calculator = 96 batteries

The total cost of the batteries will be:

96 batteries x $0.52 per battery = $49.92 (rounded to two decimal places)

The power series representation for function f(x) is; ∑ [tex](-1)^{n}[/tex] × [tex]X^{(6n+9)}[/tex] / (2n+1), and the radius of convergence is infinite, R = ∞.

To find a power series representation for the function f(x) = x⁶×arctan(x³), we can use the power series representation for arctan(x);

arctan(x) = ∑ [tex](-1)^{n}[/tex] × [tex]X^{(2n+1)}[/tex] / (2n+1)

Substituting x³ for x in this series, we have;

arctan(x³) = ∑ [tex](-1)^{n}[/tex] × (x³[tex])^{(2n+1)}[/tex] / (2n+1)

= ∑ [tex](-1)^{n}[/tex] × [tex]X^{(6n+3)}[/tex] / (2n+1)

Multiplying this series by x⁶, we get;

x⁶ × arctan(x³) = ∑ [tex](-1)^{n}[/tex] × [tex]X^{(6n+9)}[/tex] / (2n+1)

So the power series representation for f(x) is;

f(x) = x⁶ × arctan(x³) = ∑ [tex](-1)^{n}[/tex] × [tex]X^{(6n+9)}[/tex] / (2n+1)

To find radius of convergence R, we use the ratio test:

lim |[tex](-1)^{n}[/tex] × [tex]X^{(6(n+1)+9)}[/tex] / (2(n+1)+1) × (2n+1) / [tex](-1)^{n}[/tex] × [tex]X^{(6n+9)}[/tex]|

n->∞

= lim |x⁶ / (2n+3)|

n->∞

As n approaches infinity, the denominator of the fraction approaches infinity, so the limit is zero for all values of x. Therefore, the power series converges for all values of x, and the radius of convergence is infinite, R = ∞.

Step-by-step explanation:

The solution is,  the dimensions that could be used at a minimum cost is 17.32 ft of pine boards by 69.28 ft of galvanized steel.

SOLUTION

From the question, let the

Length of pine boards be represented as x and

Let the length of galvanized steel fencing be represented as y.

The diagram of Lucy Dog Daycare can be represented as follows

So, the Total cost C should include cost of two pine boards 2x and cost of one galvanized steel y.

So we have

C = 12x + 3y

Also the total area is 1,200 square.

That is

xy = 1200

or, y = 1200/x

Now substituting the value of y into the cost equation, we have

C = 12 x + 3600/x

Taking the derivative, we have

C = 12 - 3600/ x^2

At minimum or maximum cost, the derivative should be equal to zero,

So, C = 12 - 3600/ x^2 = 0

or, x^2 = 3600/ 12

or, x^2= 300

or, x = 17.32

Hence x = 17.32 ft

From the equation above, where y was made the subject, we have

y = 1200/ 17.32

Hence y = 69.28 ft

Hence the dimensions that could be used at a minimum cost is 17.32 ft of pine boards by 69.28 ft of galvanized steel

Mickey and Minnie Mouse will need to put $680.75 into their escrow account each month to cover the property taxes, homeowner's insurance, and flood insurance costs.

An escrow account is like a savings account that is managed by a mortgage servicer. The portion deposited into an escrow account usually covers estimated property taxes and your homeowners and mortgage insurance premiums.

To calculate the monthly amount Mickey and Minnie Mouse need to put into their escrow account for property taxes, homeowner's insurance, and flood insurance, we will first add up the total annual costs for these expenses:

Property taxes: $5,467

Homeowner's insurance: $1,440

Flood insurance: $1,262

Total annual costs = $5,467 + $1,440 + $1,262 = $8,169

Next, we divide the total annual costs by 12 to get the monthly escrow amount:

$8,169 / 12 = $680.75

Therefore, $680.75 is the amount they will need to put into their escrow account each month.
