does coordinate m or n represent a greater number
Answer:
m
Step-by-step explanation:
If all points are plotted on a graph, we'd see that (3, 5) and (10, 5), would be on the same horizontal level. Both points have the same y coordinate of 5.
Invariably, (0, 1) would be on the same horizontal level with (m, n). The coordinate of n, which is the y value on the y-axis would be same as 1.
The coordinate of m, which is the x-value on the x-axis would certainly be greater than 1.
Therefore, coordinate m represents a greater number.

Assume that u⋅v=4, ‖u‖=5, and ‖v‖=3. What is the value of 4u⋅(4u−7v)?
Step-by-step explanation:
It is given that,
[tex]u{\cdot}v=4\\\\|u|=5\\\\|v|=3[/tex]
We need to find the value of [tex]4u{\cdot} (4u-7v)[/tex]
Firstly, we should simplify [tex]4u{\cdot} (4u-7v)[/tex]
[tex]4u{\cdot} (4u-7v)=4u{\cdot} 4u-4u{\cdot} 7v[/tex]
Now using distributive property : x(y-z)=xy-yz
So,
[tex]4u{\cdot} (4u-7v)=4u{\cdot} 4u-4u{\cdot} 7v\\\\=16u{\cdot}u-28{u{\cdot} v}\\\\=16|u|^2-28(u{\cdot}v)\\\\=16\times 5^2-28\times 4\\\\=288[/tex]
So, the value of [tex]4u{\cdot} (4u-7v)[/tex] is 288.

Step-by-step explanation:
- 2n+1 = 3(n+ 2)
multi-step equations
Answer:
[tex] - 2n + 1 = 3n + 6 \\ - 2n - 3n = - 1 + 6 \\ - 5n = 5 \\ n = \frac{5}{ - 5} \\ n = - 1[/tex]
Answer:
n = -1
Step-by-step explanation:
Solve for n:
1 - 2 n = 3 (n + 2)
Expand out terms of the right-hand side:
1 - 2 n = 3 n + 6
Subtract 3 n from both sides:
1 + (-2 n - 3 n) = (3 n - 3 n) + 6
-2 n - 3 n = -5 n:
-5 n + 1 = (3 n - 3 n) + 6
3 n - 3 n = 0:
1 - 5 n = 6
Subtract 1 from both sides:
(1 - 1) - 5 n = 6 - 1
1 - 1 = 0:
-5 n = 6 - 1
6 - 1 = 5:
-5 n = 5
Divide both sides of -5 n = 5 by -5:
(-5 n)/(-5) = 5/(-5)
(-5)/(-5) = 1:
n = 5/(-5)
The gcd of 5 and -5 is 5, so 5/(-5) = (5×1)/(5 (-1)) = 5/5×1/(-1) = 1/(-1):
n = 1/(-1)
1/(-1) = -1:
Answer: n = -1

Explain the level of uncertainties involve in concept of probability. The next generation of miniaturized wireless capsules with active locomotion will require two miniature electric motors to maneuver each capsule. Suppose 10 motors have been fabricated but that, in spite of tests performed on the individual motors, 2 will not operate satisfactorily, when placed into a capsule. To fabricate a new capsule, 2 motors will be randomly selected, find the probability that: (i) Both motors will operate satisfactorily in the capsule. (ii) One motor will operate satisfactorily and the other will not.
Answer:
a) the probability that Both motors will operate satisfactorily in the capsule 0.6222
b) the probability that One motor will operate satisfactorily and the other will not is 0.3556
Step-by-step explanation:
Given that;
total number of motors N = 10
number of motors will not operate satisfactory m = 2
number of motors randomly selected n = 2
let X be number of motors will that will not operate successfully
here, X≅Hyper geometric (x; N,n,m)
The probability mass function of x is;
P (X = x)= { m } {N - m }
{x } {n - x}
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
{ N }
{ n }
a)
the probability that both motors will operate satisfactorily in the capsule i.e no motor will not operate satisfactory
so
P(X= 0) = { 2 } { 10 - 2 }
{0 } { 2 - 0}
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
{ 10 }
{ 2 }
so
P (X = 0) = { 2 } { 8}
{ 0 } { 2 }
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
{ 10 }
{ 2 }
p(P= 0)=1×28 / 45 = 28/45 = 0.6222
Therefore the probability that Both motors will operate satisfactorily in the capsule 0.6222
b)
the probability that one motor will operate satisfactorily and the other will not.
P(X=1) = { 2 } { 10 - 2 }
{ 1 } { 2 - 1 }
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
{ 10 }
{ 2 }
so
P(X=1) = { 2 } { 8 }
{ 1 } { 1 }
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
{ 10 }
{ 2 }
P(X=1) = 2×8 / 45 = 16/45 = 0.3556
Therefore the probability that One motor will operate satisfactorily and the other will not is 0.3556

For a shape with a cutout, the shaded area is the difference between the area of the enclosing shape and the area of the cutout. The applicable area formulas are ...
area of rectangle: A = bh
area of triangle: A = (1/2)bh
Here, the dimensions are given as binomials (2-term polynomials), so you have to multiply those to find the areas. The distributive property is helpful for that.
__
30) shaded area = (5x+8)(6x+2) -(5x)(x+6)
= (5x)(6x+2) +8(6x+2) -5x^2 -30x
= 30x^2 +10x +48x +16 -5x^2 -30x
shaded area = 25x^2 +28x +16
__
31) shaded area = (1/2)(x+6)(2x+5) -x(x+1)
= (1/2)(x(2x+5) +6(2x+5)) -x^2 -x
= (1/2)(2x^2 +5x +12x +30) -x^2 -x
= x^2 +(17/2)x +15 -x^2 -x
shaded area = (15/2)x +15
__
32) volume = lwh = (2x -5)(3x +2)(3x +2)
= (2x -5)(3x(3x +2) +2(3x +2))
= (2x -5)(9x^2 +6x +6x +4)
= (2x -5)(9x^2 +12x +4)
= 2x(9x^2 +12x +4) -5(9x^2 +12x +4)
= 18x^3 +24x^2 +8x -45x^2 -60x -20
volume = 18x^3 -21x^2 -52x -20

Convert the following fraction to a percentage (round to the nearest tenth if needed). 3/7
Answer:
[tex]\huge\boxed{42.9 \%}[/tex]
Step-by-step explanation:
=> [tex]\frac{3}{7}[/tex]
To make it a percentage, we need to multiply and divide it by 100
=> [tex]\frac{3}{7} * \frac{100}{100}[/tex]
=> [tex]\frac{300}{700}[/tex]
To make the denominator 100, we'll divide the numerator and denominator by 7
=> [tex]\frac{300/7}{700/7}[/tex]
=> [tex]\frac{42.9}{100}[/tex]
Percentage means out of hundred, so it becomes
=> 42.9 %
For income tax purposes, a man uses a method called
straight-line depreciation to show the loss in value of a copy
machine he recently purchased. A man assumes that he can
use the machine for 5 years. The following graph shows the
value of the machine over the years. What loss in value
occurred during the first year?
Answer: It lost $6.75 in the first year.
Step-by-step explanation: Using the graph, first determine the function of loss in value and years, by calculating:
Slope: m = [tex]\frac{y_{a}-y_{b}}{x_{a}-x_{b}}[/tex] and then, substitute in: [tex]y-y_{0}=m(x-x_{0})[/tex]
The equation is:
[tex]y-y_{0}=(\frac{y_{a}-y_{b}}{x_{a}-x_{b}} )(x-x_{0})[/tex]
Assuming y is value and x is years.
From the graph, in year 0, loss is 10 and in year 4, loss is 7, i.e.:
[tex]y-10=(\frac{7-10}{4-0} )(x-0)[/tex]
[tex]y=\frac{-3}{4}x+10[/tex]
For the first year, loss in value will be:
[tex]y=\frac{-3}{4}.1+10[/tex]
y = 6.75
During the first year, the loss in value is $6.75

What is the solution to this equation?
6x + 10 - 2x= 7 + 23
Answer:
[tex]\boxed{x=5}[/tex]
Step-by-step explanation:
First, you need to combine like terms in order to begin simplifying. This is done by subtracting 2x from 6x. Also, add 7 to 23.
6x + 10 - 2x = 7 + 23
4x + 10 = 7 + 23
4x + 10 = 30
Now, you have a two-step equation. Subtract 10 from both sides, and then divide by 4.
4x + 10 = 30
4x = 20
x = 5 is the final answer.

Step-by-step explanation:
2x+3y=8 9x-3y = 14
solve by substitution
Answer: x=2 and y=4/3
Step-by-step explanation:
To solve by substitution method, you want to solve for one variable, and plug it into the other equation.
Let's solve for y in 2x+3y=8.
[tex]2x+3y=8[/tex] [subtract both sides by 2x]
[tex]3y=8-2x[/tex] [divide both sides by 3]
[tex]y=\frac{8-2x}{3}[/tex]
Now that we have y, we can plug it into the second equation.
[tex]9x-3y=14[/tex] [plug in y]
[tex]9x-3(\frac{8-2x}{3} )=14[/tex] [multiply 3 and y to cancel out the 3]
[tex]9x-(8-2x)=14[/tex] [distribute -1 to 8-2x]
[tex]9x-8+2x=14[/tex] [combine like terms]
[tex]11x-8=14[/tex] [add both sides by 8]
[tex]11x=22[/tex] [divide both sides by 11]
[tex]x=2[/tex]
Since we know the value of x, we can substitute it back into any of the 2 equations to find y.
[tex]2x+3y=8[/tex] [plug in x=2]
[tex]2(2)+3y=8[/tex] [multiply 2 and 2]
[tex]4+3y=8[/tex] [subtract both sides by 4]
[tex]3y=4[/tex] [divide both sides by 3]
[tex]y=\frac{4}{3}[/tex]
Our final answer is x=2 and y=4/3.

Step-by-step explanation:
Since ray GI bisects ∠FGH, we know that the ray is in the middle of the angle, since it is a bisector. That means that both angles have the same value. ∠FGI is equal to 51º. Since we know that both of the angles are the same value, that makes m∠IGH also equal to 51º. To find the angle of m∠FGH, we add both angles together to get our answer: 102º.
Answers:
m∠IGH = 51º
m∠FGH = 102º
