The radius of a sphere is 6 inches. Find the length of a chord connecting two perpendicular radii

Answers

i think not to sure

6 sqrt 2

Answer:

Hence, the length of the chord joining two perpendicular radii is:

6√2 inches.

Step-by-step explanation:

Let r denote the radius of circle.

i.e. r=6 inches.

Let AB be the chord that connects two perpendicular radii i.e. OA and OB whose lengths are given to be 6 inches.

We can apply pythagorean theorem to find the length of the chord.

[tex]AB^2=OA^2+OB^2\\\\AB^2=6^2+6^2\\\\AB^2=36+36\\\\AB^2=72\\\\AB=\sqrt{72}\\\\AB=6\sqrt{2}[/tex].

Find the slope of a parallel line to 5x+2y=6

Answers

I’m pretty sure the slope is -5/2

Answer: [tex]\dfrac{-5}{2}[/tex]

Step-by-step explanation:

We know that equation in intercept form is given by :-

[tex]y=mx+c[/tex] , where m is the slope of the line {Coefficient of x}

The given equation of a line : [tex]5x+2y=6[/tex]

First rewrite the given equation in intercept form , we get

[tex]2y=6-5x\\\\\Rightarrow\ y=\dfrac{1}{2}(6-5x)\\\\\Rightarrow\ y=\dfrac{-5}{2}x+\dfrac{6}{2}\\\\\Rightarrow\ y=\dfrac{-5}{2}x+3[/tex]

Photo necessities produces camera cases. They have found that the cost , c (x) of making x camera cases is a quadratic function in terms of x.

The company also discovered that it cost $45 to produce 3 camera cases $257 to produce 7 camera cases and $792 to produce 12 camera cases.


Find the total cost producing 1 camera case

Answers

The first thing you should know is that to define a quadratic function you need three points.
 In this case the points will be:
 (3. 4. 5)
 (7, 257)
 (12, 792)
 The equation of the quadratic function in this case will be:
 c (x) = 6x ^ 2 - 7x + 12
 Therefore for x = 1 we have:
 c (1) = 6 * (1) ^ 2 - 7 * (1) + 12
 c (1) = 11 $
 Answer:
 Total cost producing 1 camera case is:
 c (1) = 11 $
Answer:

The total cost producing 1 camera case is:

                            $ 11

Step-by-step explanation:

Let the quadratic function be:

[tex]c(x)=ax^2+bx+c[/tex]

Now, c(3)=45

This means:

[tex]9a+3b+c=45------------(1)[/tex]

c(7)=257

This means that:

[tex]49a+7b+c=257----------------(2)[/tex]

and c(12)=792

This imply:

[tex]144a+12b+c=792-------------------(3)[/tex]

On subtracting first equation from second we get:

[tex]40a+4b=212------------(4)[/tex]

and on subtracting second equation from third we get:

[tex]95a+5b=535-----------(5)[/tex]

Now on multiplying equation (4) by 5 and equation (5) by 4 and subtracting both equation we get:

a=6

Putting value of a in equation (4) we get:

b= -7

and putting the value of a and b in equation (1) we get:

c=12

Hence, the cost function is:

[tex]c(x)=6x^2-7x+12[/tex]

Now, the cost of producing 1 camera will be the value of c(x) when x=1

i.e.

[tex]c(1)=6-7+12\\\\\\c(1)=11[/tex]

                 Hence, the answer is:

                        $ 11

HELP PLEASE! Are the two triangles similar? How do you know?

Answers

No, they are both measuring a different degree range, I hope this helps

Answer:

The two triangles are similar by AAA

Step-by-step explanation:

we know that

If the two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

Remember that

The sum of the internal angles of a triangle must be equal to [tex]180\°[/tex]

so

In the triangle CDE

Find the measure of angle E

[tex]m<C+m<D+m<E=180\°[/tex]

substitute the values and solve for m<E

[tex]60\°+53\°+m<E=180\°[/tex]

[tex]m<E=180\°-(60\°+53\°)=67\°[/tex]

The measures of internal angles triangle CDE are [tex]60\°-53\°-67\°[/tex]

In the triangle FGH

Find the measure of angle G

[tex]m<F+m<G+m<H=180\°[/tex]

substitute the values and solve for m<G

[tex]60\°+m<G+67\°=180\°[/tex]

[tex]m<G=180\°-(60\°+67\°)=53\°[/tex]

The measures of internal angles triangle FGH are [tex]60\°-53\°-67\°[/tex]

therefore

peter makes $6 per hour doing yard work plus $10 every house if pter does yard work for 6 houses and receives a paycheck for $210 how many hours did he work

Answers

So the equation is 6x+10y=z and you can plug in y and z then it’s 6x+10*6=210. Simplifying can get you 6x=150 then divide by 6 to get 25.



The answer is 25 hours.

After calculating Peter's earnings from working on 6 houses, the remaining amount from his total paycheck indicates that he worked for 25 hours at his hourly wage of $6.

To determine how many hours Peter worked when he received a paycheck for $210, we need to consider his earnings per house and his hourly wage. Peter makes $6 per hour for doing yard work plus $10 for every house he does work on.

First, we calculate the total earnings from the houses he worked on. Since he did yard work for 6 houses, we multiply 6 houses by $10 per house:

6 houses times $10 per house = $60

Now, subtract the total earnings from houses from his total paycheck to find out how much he earned from hourly wages:

$210 (total paycheck) - $60 (earnings from houses) = $150 (earnings from hourly wage)

$150 / $6 per hour = 25 hours

So, Peter worked 25 hours doing yard work.

The largest doll is 12 inches tall. The height of each of the other dolls is

710
the height of the next larger doll. Write an expression involving a power for the height of the smallest doll. Then evaluate the expression to find the height of the smallest doll to the nearest tenth of an inch.

Answers

The first doll is 12 inches.
To get the next smallest doll (the second) we multiply 12 by 7/10.
To get the one after that (the third) we multiply 12 by 7/10 by 7/10
To get the one after that (the fourth) we multiply 12 by 7/10 by 7/10 by 7/10
and so on...

The height of each doll after the first will be multiplied by (7/10) raised to a power. Let's call n the number of the doll (first, second, third, ...). It might be easier to determine the power if we write it like this:

First Doll -> n =1 -> height = 12
Second Doll -> n=2 -> height = [tex](12)( \frac{7}{10}) ^{1} [/tex]
Third Doll -> n = 3 -> height = [tex](12)( \frac{7}{10}) ^{2} [/tex]
Fourth Doll -> n=4 -> height = [tex](12)( \frac{7}{10}) ^{3} [/tex]

Notice that the exponent of the fraction (7/10) is always one less than the value of n. This even works for the first doll. It's height is [tex](12)( \frac{7}{10}) ^{0} [/tex]

Thus, we have an expression for the height of the nth doll and it is [tex](12)( \frac{7}{10}) ^{n-1} [/tex]

The height of any doll can be found using this formula. Whatever the smallest doll is (the 10th, 27th, 99th, etc.) just use that number for n. Since we arrive at each height by multiplying the prior by (7/10) the heights form a geometric sequence.

A rectangular auditorium seats 13201320 people. the number of seats in each row exceeds the number of rows by 1414. find the number of seats in each row.

Answers

esssssskeeeeeeetit its litty gucci
Final answer:

The number of rows in the auditorium is 45, and each row has 59 seats.

Explanation:

This problem can actually be solved using Algebra. If we let 'x' represent the number of rows in the auditorium, then the number of seats in each row would be x + 14 (since the number of seats in each row exceeds the number of rows by 14). Since the total number of seats is 1320, we can now set up and solve an equation: x(x + 14) = 1320.

Solving the equation, we get [tex]x^2[/tex] + 14x - 1320 = 0. This can be factored to (x - 45)(x + 29) = 0. The positive solution is x = 45. Therefore, there are 45 rows in the auditorium.

Substituting x = 45 back to our original equation x + 14, we find out that there are 45 + 14 = 59 seats in each row.

You have five identical pieces of equipment. There is a 1 in 10 chance that each piece will fail in a year. What is the likelihood that NONE of the pieces fail during a year?

Answers

Assuming failures are independent (not due to design flaw), the probability of no failures is
.. (1 -0.1)^5 = 0.59049

The probability that none of the five identical pieces of equipment will fail during a year is approximately 59.049%, calculated using the statistical independence of each piece's probability of not failing, which is 0.9, raised to the power of 5.

The question is asking for the probability that none of the five pieces of equipment fails within a year when there is a 1 in 10 chance of failure for each piece of equipment. To calculate this, we use the principle of statistical independence. If the chance that one piece of equipment does not fail is 9 in 10 (or 0.9), then the probability that all five do not fail is 0.9 raised to the power of 5.

Mathematically, this is calculated as:

[tex](0.9)^5[/tex]= 0.9 * 0.9 * 0.9 * 0.9 * 0.9

Performing the multiplication, the probability that none of the five pieces fail during a year is approximately 0.59049.

In conclusion, there is a 59.049% chance that none of the identical pieces of equipment will fail during a year, assuming that the failures are statistically independent events.

Answers

Given the equation 2x-3y+4z=12, to calculate the intercepts we proceed as follows:
x-intercept:
To get x-intercept we let y=0 and z=0. The substitute these values in our equations follows:
2x+3(0)+4(0)=12
2x=12
hence:
x=12/2
x=6
therefore the x-intercept will be at point (6,0,0)

y-intercept:
To calculate for y-intercept we let x=0 and z=0 and substitute the values in the equation, here we shall have:
2(0)-3y+4(0)=12
solving for y we get:
-3y=12
hence:
y=12/(-3)
y=-4
therefore the y-intercept is at point (0,-4,0)

z-intercept:
To get the z-intercept we let x=0 and y=0, the we substitute the values in the equation as follows:
2(0)-3(0)+4z=12
solving for z we get:
4z=12
z=12/4
z=3
hence the z-intercept is at (0,0,3)

Area of ∆ACD = 30.

Since we know the area of ΔACD as well as the measurement of the base, we will use these to find the length of the altitude.  The formula for the area of a triangle is A=1/2bh.  Our area is 30 and our base is 10, so we have:
30=1/2(10)h
30=5h
Divide each side by 5:
30/5=5h/5
6=h
The height of the triangle is also the height of the trapezoid.  We can now find the area of the trapezoid.  The formula we need is A=1/2(B+b)h.  Substituting our numbers in, we have:

Sometimes when you're given dimensions that differ by some amount, it is easier to work with their average value. Let x represent the average of length and width of the rectangle. The length and width differ from this average value by 1.5 m. Then the area is
.. (x +1.5)*(x -1.5) = 154
.. x^2 -2.25 = 154
.. x^2 = 156.25
.. x = 12.5
The width is 1.5 m shorter than this, or 11 m.

Solved in the conventional way, you are looking for factors of 154 that differ by 3. This means you have to find the factors of 154, or use the quadratic formula.
