Determine the distance between L(1, 4, 7) and M(2, 9, 8) on a three-dimensional plane.
XY = √(x2 – x, )²+ (y2 – yı)2 + (x2 – 21)2
Answer:
Distance LM = 5.20 unit (Approx.)
Step-by-step explanation:
Given coordinates;
L(1, 4, 7) and M(2, 9, 8)
Find:
Distance LM
Computation:
Distance between three-dimensional plane = √(x2 - x1)² + (y2 - y1)² + (z2 - z1)²
Distance LM = √(2 - 1)² + (9 - 4)² + (8 - 7)²
Distance LM = √(1)² + (5)² + (1)²
Distance LM = √1 + 25 + 1
Distance LM = √27
Distance LM = 3√3 unit
Distance LM = 3(1.732)
Distance LM = 5.196
Distance LM = 5.20 unit (Approx.)
The product of some number and 40 is 2600
Answer:
65
Step-by-step explanation:
To find the second factor of a multiplication problem with only the answer and the first factor, divide the answer by the first factor.
[tex]2600/40= 65.[/tex]
Therefore, 40 × 65 = 2600.
If the rectangular fish tank below is completely filled with water, and the 900 cubic centimeters are poured out, how high will the water
Answer:
The high of the water is 2 cm.
Step-by-step explanation:
The equation of this volume is:
[tex]V=45*10*x[/tex]
We know that the volume is 900 cm³. So we just need to put this value in the above equation and solve it for x, which is the height.
[tex]900=45*10*x[/tex]
[tex]900=450*x[/tex]
[tex]x=\frac{900}{450}[/tex]
[tex]x=\frac{900}{450}[/tex]
[tex]x=2\: cm[/tex]
Therefore, the high of the water is 2 cm.

A sanitation department is interested in estimating the mean amount of garbage per bin for all bins in the city. In a random sample of 46 bins, the sample mean amount was 49.41 pounds and the sample standard deviation was 3.99 pounds. Construct a 92.7% confidence interval for the expected amount of garbage per bin for all bins in the city. Answer to 3 decimals (a) What is the lower limit of the 92.7% interval
Answer:
The 92.7% confidence interval for the expected amount of garbage per bin for all bins in the city is between 48.135 pounds and 50.685 pounds. The lower limit is 48.135 pounds.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 46 - 1 = 45
92.7% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 45 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.927}{2} = 0.9635[/tex]. So we have T = 2.1437
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.1437\frac{3.99}{\sqrt{45}} = 1.275[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 49.41 - 1.275 = 48.135 pounds
The upper end of the interval is the sample mean added to M. So it is 49.41 + 1.275 = 50.685 pounds.
The 92.7% confidence interval for the expected amount of garbage per bin for all bins in the city is between 48.135 pounds and 50.685 pounds. The lower limit is 48.135 pounds.

witch equation is made true by the opposite angles theorem
The option D is correct.Because this equation holds the vertically opposite angle theorem.
What is vertically opposite angle theorem?Vertically Opposite Angles are holds when two lines intersect each other then the opposite angles formed due to intersection are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are always equal to each other.
How do you find opposite angles?Vertical opposite angles that are opposite each other when two lines cross are also known as vertical angles because the two angles share the same corner. Opposite angles are also congruent angles.The equation of a vertical line is given by x = a or x = -a
Now we find
According to vertical opposite angle

-38 + -12x < -200
Answer:
-38 - 12x > -200
x = 13.5 min
Step-by-step explanation:
let x = minutes of the dive
-38 ft - 12 ft/min(x) > -200 ft
-12 ft/min(x) < -162 ft
x > -162/-12 **flip the inequality when you divide by a (-) number
x > 13.5 min
Starting at -38 ft, he has to dive longer than 13.5 minutes to go deeper than -200 ft at a rate of -12 ft/min
Identify the quotient and the remainder

The quotient is (6x + 1) and the remainder is (-7x + 1).
What is a factor of a polynomial?
We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given A cubic polynomial 24x³ - 14x² + 20x + 6 divided by 4x² - 3x + 5.
So, (24x³ - 14x² + 20x + 6)/(4x² - 3x + 5).
= (4x² - 3x + 5)(6x + 1) + (-7x + 1)/(4x² - 3x + 5) in rhe form N = DQ + R.

You're fitting a pipe into an existing fitting. The fitting allows a diameter variance of 0.001". If the interior diameter of the pipe is 0.49" and the pipe thickness is 0.005", What's the maximum allowable pipe diameter? a. 0.496, b.0.501, c. 0.499, d. 0.541
The maximum allowable pipe diameter is given as : 0.501. Option B
How to solve for the diameterFrom the question the interior diameter of the pipe is said to be 0.49
The pipe is said to have the thickness of 0.005 inches.
The exterior diameter of the pipe would be solved as 0.49 + 2 * 0.005
= 0.49 + 0.01
= 0.5
The questions said the variance in the diameter of this pipe is 0.001
Then the maximum allowable pipe diameter would be solved as: 0.001 + 0.5 = 0.501

Determine if this is a function.
I did the vertical line test, but I'm still a bit confused.
Answer: This is not a function
Why not?
The input x = 2 leads to more than one output. In this case, it leads to y = 20 and y = 40 simultaneously. This is the reason why we don't have a function. A function is only possible if each input x leads to exactly one y output.
Put another way: we cannot have x repeating any values if we want a function.
Side note: We could have y repeat however. So it's possible to have a function with the two points (1,5) and (3,5).
1. Solve for x.
a) 25 + 10(12 - x) = 5(2x - 7)
b) 6 + 2x > 20 or 8+XsO
Answer:
a) x=9
b)x>7 or x≤-8
Step-by-step explanation:
Find the value of b such that the system of equations does not have a solution.
bx - 20y = -11
-6x – 15y = 11
b=
b= 8
Step-by-step explanation:
If we rewrite the 2nd equation, it becomes
15y = -6x - 11 ---> y = (-2/5)x - (11/15)
In order for this system of equations to have no solution, they must have the same slope, i.e., they're parallel to each other. So rewriting the 1st equation,
20y = -bx + 11
---> -b/20 = -0.4 or b = 8
38) Your bank account has$82in it when you write checks for$54,$35, and$15. You then deposit $35and $42. How much is in the account? Are you overdrawn
the answer is 55 can you show me how to get that answer.
If you have $82 in your bank account and you write checks for $54, $35, and $15, then the total amount you have written in checks is $54 + $35 + $15 = $104.
So the remaining balance is $82 - $104 = -$22, which means you are now overdrawn.
After you deposit $35 and $42, the new balance will be $82 - $22 + $35 + $42 = $155
So after the deposit, the account balance is $155
It is important to keep track of your bank account balance, if you do not have enough funds in the account and the check you wrote is cashed the bank will bounce the check and incur additional fees.
Three balls are packaged in a cylindrical container as shown below. The balls just touch the top, bottom, and the sides of the cylinder. The diameter of each ball is 13 cm.
Answer:
a. 5177 cm³
b. 3,451 cm³
c. 67%
Step-by-step explanation:
Given:
Diameter of each ball (d) = 13 cm
Radius of the ball (r) = radius of the cylinder = ½(13) = 6.5 cm
Height of the cylinder (h) = the sum of the diameters of the 3 balls = 3(13) = 39 cm
a. Volume of cylinder = πr²h
Plug in the values
Volume of cylinder = π*6.5²*39 = 5176.56 ≈ 5177 cm³
b. Total volume of the three balls = 3(volume of 1 ball) = 3(volume of sphere) = 3(⁴/3πr³)
Plug in the value
Total volume of the 3 balls = 3(⁴/3*π*6.5³) = 3(1150.35) = 3,451.05 ≈ 3,451 cm³
c. % of volume of the container occupied by the 3 balls = total volume of the three balls / volume of cylinder × 100
Plug in the values
= 3,451/5177 × 100
= 66.6602279
≈ 67%
