Answer:
y= -1/2x+4
Step-by-step explanation:
slope = rise/run on the graph. the graph is going down, so it's negative. find where the line intersects the graph at a point and then count the squares up and over until it meets again. the line meets at (6,1), you count up one square and over 2 and it meets again. this gives you your rise/run = 1/2. the y intercept is where the line intersects the y axis. here the y intercept is 4 because the like goes through 4 at the y axis.

The path of a breaching ocra whale can be modeled by the function k(x) = x^2 - 2x - 8, where x is the time elapsed in seconds under water, and k(x) is the height in ft below the water.
Determine HOW LONG is the ocra (killer) whale underwater to the nearest second. MUST BE SOLVED ALGEBRAICALLY!
Answer:
The time duration of the ocra whale spends under water is 4 seconds
Step-by-step explanation:
The equation that model the path of the ocra whale is presented as follows;
k(x) = x² - 2·x - 8
Where;
x = The time elapsed in seconds under water
k(x) = The height in feet below water
Therefore, the point where the ocra whale enters the water, k(x) = 0
At the point of submerging below the water surface, we have;
k(x) = 0 = x² - 2·x - 8
Factorizing the quadratic equation gives;
0 = x² - 2·x - 8 = (x - 4)·(x + 2)
Therefore, when k(x) = 0, either;
(x - 4) = 0, which gives, x = 4
(x + 2) = 0, which gives, x = -2
Given that 'x' represent the time, the time elapsed while the whale is under water, x = 4 seconds
Put the following equation of a line into slope-intercept form, simplifying all fractions.
9x+12y=-84
Answer:
y = (-3/4)x + 7
Step-by-step explanation:
Answer:
y = -3/4x - 7
Step-by-step explanation:
Slope Intercept form: y=mx + b where m = slope and b = intercept.
Isolate y.
9x + 12y = -84
-9x -9x (subtract 9x from both sides)
12y = -9x - 84
(divide by 12)
y = -9/12x - 7
(simplify fraction)
y = -3/4x - 7

work out the surface area of this cylinder with a diameter of 6cm and a height of 25 cm
Answer:
527.52cm^2
Step-by-step explanation:
First we need to find the eqauation of this which is:
2 pi*r^2 + 2 pi*r*h
The raduis is half of the diameter so 3
Now just plug in the values and solve
2*3.14*3^2 + 2*3.14*3*25
The answer is 527.52
If you were to round it you would get
527.5 or 528

Two different cross sections are taken parallel to the base of a three-dimensional figure. The two cross sections are the same shape, but are not congruent.
Which could be the three-dimensional figure? Select three options.
cone
cylinder
triangular prism
triangular pyramid
square pyramid
A. cone
D. triangular pyramid
E. square pyramid
(Look at the photo at the bottom.)
Step-by-step explanation:First, know what a cross section is. A cross section is the exposed shape or surface when a straight cut is made through a 3D figure. For example, if I make a cross section, or cut, through a sphere, the cross section will be a circle. The newly exposed surface is in the shape of a circle.
We want to know which 3D figures can make 2 different cross sections, parallel to the base, that are congruent. Congruent means same shape but different size. Parallel to the base means the cut is completely horizontal.
A cone is one, because no matter where you horizontally cut this, the cross section will always be a circle, but different sizes.A triangular pyramid is another, because no matter where you horizontally cut this, the cross section will always be a triangle, but different sizes.A square pyramid is another, because no matter where you horizontally cut this, the cross section will always be a square, but different sizes.Here's a photo of Edge incase you're doubtful.

Ms. Jones has downloaded some songs. She then downloads 18 more songs. She now has a total of 120 songs.
Create an equation to represent the total number of songs Ms. Jones has downloaded. Let s represent the number of songs Ms. Jones had before she downloaded 18 more songs. Enter your equation in the first response box.
Enter the number of songs represented by s in the situation. Separate your equation from your number with a comma.
need help
Answer:
s+18=120
s=102
Step-by-step explanation:
Basically, she had 120 after everything was done, so we know 120 is on the right side of the equal sign. We know she had an unknown number of songs and after she added 18 it was 120. That means the equation is s+18=120
Now to solve it is simple, just isolate s by subtracting 18 on both sides.
s+18=120
-18 -18
s=102

3) In another game, there are 10 marbles in a box. 6 are red and 4 are blue. You
pull one marble from the box, don't put it back, and then pull another marble.
Calculate the following probabilities:
a) Pulling two reds.
b) Pulling two blues.
c) Pulling one of each.
Part (A)
We have 6 red and 4 blue marbles, so 6+4 = 10 total.
The probability of getting red is 6/10 since we have 6 red out of 10 total.
The probability of getting another red is 5/9 because we don't put the first marble back.
The probability of getting two reds in a row is (6/10)*(5/9) = 30/90 = 1/3
Answer: 1/3========================================================
Part (B)
4/10 represents the probability of getting blue on the first try
3/9 represents the probability of getting a blue marble on the second try
We don't put the marble back.
(4/10)*(3/9) = 12/90 = 4/30 is the probability of getting two blues in a row.
Answer: 4/30========================================================
Part (C)
Add up the results of parts (A) and (B)
1/3 + 4/30
10/30 + 4/30
(10+4)/30
14/30
7/15
The result 7/15 is the probability of either getting two reds OR getting two blues (pick one case only). This tells us that 7 out of 15 times we'll have this happen. This must mean the remaining 8 times will have two marbles of different colors.
So 8/15 is the probability of picking one marble of each color.
------
As an alternative, we could also consider it like this
(6/10)*(4/9) = 24/90 = 4/15
This represents the probability of picking red first, then blue next.
Similarly,
(4/10)*(6/9) = 24/90 = 4/15
represents the probability of picking blue first, then red next.
Therefore, 4/15+4/15 = 8/15 is the probability of getting one of each color.

Answer:
Mean = 10
Variance = 30.89
Standard Deviation = 5.56
Step-by-step explanation:
Find the Mean, Variance and Standard deviation
6, 14, 8, 2, 11, 7, 12, 4, 18, 18
Step 1
We rearrange the data and find the Mean
2, 4, 6, 7, 8, 11, 12, 14, 18, 18
Mean = Sum of values/Number of values
= 2 + 4+ 6+ 7+ 8 + 11 + 12 + 14 + 18 +18/10
= 100/10
= 10
Step 2
We find the variance of this sample days ma
Variance = (x - Mean)²/n - 1
n = 10
Hence,
=( (2 - 10)² +(4 - 10)²+ (6 - 10)²+ (7 - 10)² + (8 - 10)² + (11 - 10)² + (12 - 10)² + (14 - 10)² + (18 - 10)² +(18 - 10)²) /10 -1
= ( 64 + 36 + 16 + 9 + 4 + 1 + 4 + 16 + 64 +64)/9
= 278/9
= 30.88888889
Approximately = 30.89
Step 3
Standard Deviation = √Variance
= √30.89
= 5.5578772926
Approximately = 5.56

A number when divided by 780 gives remainder 38 .What
reminder would be obtained by dividing same number by 26?
Given:
A number when divided by 780 gives remainder 38.
To find:
The reminder that would be obtained by dividing same number by 26.
Solution:
According to Euclis' division algorithm,
[tex]a=bq+r[/tex] ...(i)
Where, q is quotient and [tex]0\leq r<1[/tex] is the remainder.
It is given that a number when divided by 780 gives remainder 38.
Substituting [tex]b=780,\ r=38[/tex] in (i), we get
[tex]a=(780)q+38[/tex]
So, given number is in the form of [tex]780q+38[/tex], where q is an integer.
On dividing [tex]780q+38[/tex] by 26, we get
[tex]\dfrac{780q+38}{26}=\dfrac{780q}{26}+\dfrac{38}{26}[/tex]
[tex]\dfrac{780q+38}{26}=30q+\dfrac{26+12}{26}[/tex]
[tex]\dfrac{780q+38}{26}=30q+\dfrac{26}{26}+\dfrac{12}{26}[/tex]
[tex]\dfrac{780q+38}{26}=30q+1+\dfrac{12}{26}[/tex]
Since q is an integer, therefore (30q+1) is also an integer but [tex]\dfrac{12}{26}[/tex] is not an integer. Here 26 is divisor and 12 is remainder.
Therefore, the required remainder is 12.

Find the surface area
Answer:
352 m
Step-by-step explanation:
The area of a trapeze is (the biggest base + the smallest base) × height / 2
The area from rectangles are side a × side b
Trapeze: (6+12)×4/2 = 36
Rectangles: 5 × 10 = 50
6 × 10 = 60
12 × 10 = 120
There are two trapeze andtwo rectangles with the samesize, so you double their area:
2×36 + 2 × 50 + 60 + 120 = 352 m
