Step-by-step explanation:
if (x,y) is the centroid. Then x=(x1+x2+x3)/3,y=(y1+y2+y3)/3
5.
x=(-2+4+10)/3=4
y=(6+0+6)/3=4
centroid=(4,4)
6.
x=(3+5-2)/3=2
y=(3-1+1)/3=1
centroid=(2,1)
Determine the intercepts of the line.
-5x – 4y = 10
y-intercept:
X-intercept:
Answer:
y - intercept = -5/2
x-intercept = -2
Step-by-step explanation:
-5x - 4y = 10
At y-intercept , x = 0
0 - 4y = 10
y = 10/-4
y = -5/2
At x-intercept, y = 0
-5x - 0 = 10
-5x = 10
x = 10/-5
x = -2

Step-by-step explanation:
1.8y-9.3y-6.3y I don't get it
Answer:
-13.8y
Step-by-step explanation:
Since these all have the same variable you don't need to worry that much. Let's take away the y to make it easier. Now you just subtract normally.
1.8 - 9.3
A trick that I use is that I subtract 9.3 - 1.8, and then add a negative sign. So that is -7.5
Then, subtract -7.5-6.3. You add these because they have the same symbol. So it is -13.8
We can't forget about the variable!! So it is -13.8y
Hope this helps!!

Answer:
Adding them together. x = 3/2, y = 8
Step-by-step explanation:
Adding because we want to get rid of a variable. If we add, 2x + 6x = 8x, 1/2 * y + (-1/2 * y) = 0, and 7 + 5 = 12. Adding gets rid of the y variable.
By adding we get that 8x = 12 which gives us x = 12/8 = 3/2
Substituting this back into either equation will give us y = 8.

Which expression is correct for “y”?
Answer: A
Answer:
y = tan-1 (31/23)
Formula: SOHCAHTOA
TOA: tan = opposite/adjacent
31 / 23 = 1.3478
tan-1 of 1.3478 is 53.4264
53.4264 = 53 (rounding to the nearest degree)
y = 53 degrees

Find the mode of 7 , 3 , 2 , 5 , 0. Single choice.
2
0
No mode
Answer:
No mode
Step-by-step explanation:
The mode is the statistical method in which the most repetitive number should be considered
Like if we take an example
1,1, 2, 2, 2, 4, 4,4,4
So here the mode is 4 as 4 is repeated 4 times
But in the given situation there is no mode as every number is written single time
Express in simplest form with a rational denominator.

There are 101 Year 13 pupils in a tennis club, out of a total of 146 pupils. Write this proportion as a percentage. Give your answer correct to 1 decimal place when appropriate.
Answer: 69.2%
Step-by-step explanation:
There are 101 Year 13 students out of a total number of 146 pupils.
To find this as a percentage, divide the total number of students by the year 13 students and then multiply by 100%:
= Year 13 students/ Total students * 100%
= 101 / 146 * 100%
= 0.692 * 100%
= 69.2%

The expected value is an extension of the weighted average in probability theory. The expected value for the given binomial distribution is 4.
What is Expected value?The expected value is an extension of the weighted average in probability theory. Informally, the anticipated value is the arithmetic mean of a large number of independently chosen random variable outcomes.
Expected value, E(x) = ∑(Px)
where P is the probability and x is the random distribution value.
The expected value for the given binomial distribution is,
Expected value = Random variable × Probability
E(x) = ∑(Px)
= 0(1/3125) + 1(4/625) + 2(32/625) + 3(128/625) + 4(256/625) + 5(1024/3125)
= 0 + (4/625) + (64/625) + (384/625) + (1024/625) + (5120/3125)
= 0 + 0.0064 + 0.1024 + 0.6144 + 1.6384 + 1.6384
= 4
Hence, the expected value for the given binomial distribution is 4.

Re-write the quadratic function below in standard form y=3(x+4)(x+1)
Answer:
y = 3x² + 15x + 12
Step-by-step explanation:
A quadratic function in standard form is
y = ax² + bx + c ( a ≠ 0 )
Given
y = 3(x + 4)(x + 1) ← expand the factors using FOIL
= 3(x² + 5x + 4) ← distribute parenthesis by 3

10) [tex]\frac{t^2+2t-24}{t^2-36}[/tex]
Factor t^2 + 2t - 24
What two numbers add to 2 and multiply to -24?
6 and -4 so
(t + 6)(t - 4) is the factored form
t^2 - 36 factored is => because of a^2 - b^2 = (a - b)(a + b)
[tex]\frac{(t + 6)(t - 4)}{(t + 6)(t - 6)} = \frac{t-4}{t-6}[/tex]
Since we cancelled out be t + 6, t + 6 ≠ 0, t ≠ -6
And since the denominator is t - 6, t - 6 ≠ 0, t ≠ 6
[tex]\frac{t-4}{t-6}[/tex] , t ≠ -6, t ≠ 6

How many sides does a polygon have if the sum of interior angles is equal to 18 right angles ? ( please give the answer with explanations if possible)
Answer:
11
Step-by-step explanation:
So the sum of the angles is 18 × 90 = 1620
the formula to find number of sides is n which is sides - 2 into 180 equals sum of interior angles
(n-2)*180 = 1620
n-2 = 1620/180
n- 2 = 9
n = 11

Activity
On the way home from visiting his family, Vincent's plane cruised at an altitude of 3.2 x 104 feet. He had heard that a man named Felix
Baumgartner skydived from an altitude of 1.28 x 10$ feet. Vincent wants to know how much higher Felix went on his skydiving trip.
write the cruising altitude of vincent’s plane in standard notation
Answer:
Vincent’s plane is cruising at an altitude of 3.2 × 10^4 feet.
Convert the number to standard notation.
3.2 × 10^4 feet
=
3.2 • 10,000 feet
=
32,000 feet
Step-by-step explanation:
This is the sample answer from Edmentum.
Answer:
Question 1 part a =
Vincent’s plane is cruising at an altitude of 3.2 × 104 feet.
Convert the number to standard notation.
3.2 × 104 feet
= 3.2 • 10,000 feet
= 32,000 feet
Part b =
Felix’s skydiving altitude is 1.28 × 105 feet.
Convert the number to standard notation.
1.28 × 105 feet
= 1.28 • 100,000
= 128,000 feet
Part c =
Subtract the two altitudes to find the difference.
128,000 feet − 32,000 feet = 96,000 feet
The difference of their altitudes is 96,000 feet.
Part d =
The difference of the altitudes is 96,000 feet.
Covert 96,000 to scientific notation:
96,000 feet = 9.6 × 104 feet
Question 2 part a =
Vincent’s plane’s altitude is 3.2 x 10^4 feet.
Felix’s skydiving altitude is 1.28 x 10^5 feet.
Transform 3.2 x 10^4 so its exponent matches the power of 10 in 1.28 x 10^5.
To do so, multiply and divide the number by 10.
3.2 x 10^4 = 10/10 x 3.2 x 10^4
= 3.2/10 x 10^4 x 10
= 0.32 x 10^5
Part b =
Calculate the difference of the two altitudes:
1.28 × 105 – 0.32 × 105
= (1.28 – 0.32) • 105
= 0.96 • 105
The difference of their altitudes is 0.96 •105 feet.
Part c =
The difference of Vincent’s and Felix’s altitudes is 0.96 x 10^5 feet.
To convert the answer to scientific notation, multiply and divide the number by 10.
0.96 x 10^5 = 10/10 x 0.96 x 10^5
= (0.96 x 10) x (10^5 x 10^-1)
= 9.6 x 10^4 feet
In scientific notation, the difference of Vincent’s and Felix’s altitudes is 9.6 x 10^4 feet.
Question 3 =
The altitudes are the same. That means you can subtract numbers given in scientific notation using either of two methods: convert them to standard notation and then perform the subtraction, or subtract the numbers in scientific notation without converting them to standard notation.

Your answer is in bold. All edmentum answers :)
