what does y intercept mean ?
Answer: The vertical line on a graph representing the vertical coordinate points.
Answer:
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0. Hope this helps.

Which expression is equivalent to 60 Σ n=1 (2n − 1)2 ? Check all that apply.
9514 1404 393
Answer:
B, D
Step-by-step explanation:
The quadratic expands to ...
(2n -1)² = (2n)² +2(2n)(-1) +(-1)² = 4n² -4n +1
The coefficients can be factored out of the sum, so ...
∑(4n²) = 4∑n² for example
The sum of 60 ones is 60:
[tex]\displaystyle\sum_{n=1}^{60}{1}=1+1+1+\dots+1=60[/tex]
So, the sum can be written as ...
[tex]\displaystyle\sum_{n=1}^{60}{(2n-1)^2}\\\\=\boxed{4\sum_{n=1}^{60}{n^2}-4\sum_{n=1}^{60}{n}+\sum_{n=1}^{60}{1}}\\\\=\boxed{4\sum_{n=1}^{60}{n^2}-4\sum_{n=1}^{60}{n}+60}[/tex]

a river flows due south at 1.2 miles per hour. A swimmer attempting to cross the river heads due east swiming at 3 miles per hour relative to the water. In what direction should the swimmer head in order to arrive at a landing spot due east of his starting point
Answer:
The swimmer must move in the direction 338.2°
Step-by-step explanation:
Since the river flows due south at 1.2 miles per hour and the swimmer swims 3 miles per hour due east of the river, since their directions are perpendicular, the resultant speed is the hypotenuse of the triangle formed by the two perpendicular directions.
The direction of the resultant speed is thus θ = tan⁻¹( vertical component/horizontal component) where vertical component = 1.2 mph due south = -1.2 mph and horizontal component = 3 mph due east = + 3 mph
So, θ = tan⁻¹(-1.2 mph/+ 3mph)
θ = tan⁻¹(-1.2/3)
θ = tan⁻¹(-0.4)
θ = -21.8°
θ = -21.8° + 360° (since we are in the fourth quadrant- between east and south)
θ = 338.2°
So, the swimmer must move in the direction 338.2°.

Step-by-step explanation:
Answer:

Step-by-step explanation:
So, our inequalityis that the square root of x is eithr greater than or equal to 25.
Lets think of this as a equation, and try solving for x:
[tex]\sqrt{x} \geq 25[/tex]
Lets square both sides to get x normal:
[tex]x\geq 625[/tex]
Now, x must either be greater than or equal to this value.
Lets look at the answers:
125
-625
-5
5
700
625
Well, most these answers are below the 625.
However, some of these values look like they may be right:
-625
700
625
So, -625 cannot be it. Although it seems to be equal to to 625 above, its negative. This means its much smaller than it
We also have 625 and 700
700 is greater than 625, so that has to be an answer.
Remember that its greater than or equal to.
625 is equal to 625, so this is an answer as well.
Answers:
625 and 700

The coordinates of points A and B are A(
4-2) and B(12, 10). What are the coordinates of the point that is
is?
of the way from A to B?
Answer:
So, the answer in short is B) (6,1)
Step-by-step explanation:
If you graph the points, then you see that point A is 8 points away from point B on the X-axis. If you take 8 and divide it by 4, you get 2, so that means that the 1/4 way point is 2 points away from point A, giving you 6 as your x-axis point for this new point. B is the only one with 6 as its spot on the x axis, leaving B as the only choice. BTW you're pretty cute ;)
For each of the following situations, state the predictor variable and the outcome variable.

Answer:
C. The rudely disagrees condition has a mean of 4.16 and a standard deviation of 0.85 while the politely disagrees condition has a mean of 3.82 and standard deviation of 0.97
Step-by-step explanation:
The given data is
x` Std. Dev
R. disagrees 4.16 0.854
P. disagrees 3.82 0.967
From this data we see that the R. disagrees has a mean of 4.16 and standard deviation of 0.854
while
the P. disagrees has a mean of 3.82 and standard deviation of 0.967.
Same figures are given only in option C because
Rounding 0.854 gives 0.85
Rounding 0.967 gives 0.97
So only option C is the best choice.

Answer:
14.4 m
Step-by-step explanation:
From the question given above, the following data were obtained:
Hypothenus = 36 m
Height of building (H) = 33 m
Length of shadow (L) =?
The length of the shadow can be obtained as follow:
Hypothenus² = H² + L²
36² = 33² + L²
1296 = 1089 + L²
Collect like terms
1296 – 1089 = L²
207 = L²
Take the square root of both side
L = √207
L = 14.4 m
Therefore, the length of the shadow is 14.4 m

An equation that models the height of an object dropped from the top of a building is y= -16x^2 + 30 where x is time in sec. Another equation, y= 14, models the path of a flying bird in the air. Write a system of equations, and then solve to find how many seconds the object is in the air before it crosses the birds path
Answer:
1 second
Step-by-step explanation:
The 2 equations are
y = - 16x² + 30 → (1)
y = 14 → (2)
Substitute y = 14 into (1)
14 = - 16x² + 30 ( subtract 30 from both sides )
- 16 = - 16x² ( divide both sides by - 16 )
1 = x² ( take the square root of both sides )
x = [tex]\sqrt{1}[/tex] = 1
The object is in the air for 1 sec before it crosses the bird's path
