Find the greatest possible x-coordinate of point A such that for any point B on the y-axis between (-24) and 25, the segment AB has a common point with the line segment PQ, where P(5, -12), Q(5, 9).
Answer:
8.75
Step-by-step explanation:
You want the greatest possible x-coordinate of point A such that for any point B on the y-axis between (-24) and 25, the segment AB has a common point with the line segment PQ, where P(5, -12), Q(5, 9).
GeometryIf we designate the points on the y-axis as X(0, -24) and Y(0, 25), we find that point A must lie in the triangle bounded by lines XY, XP, and YQ. The x-coordinate of the point of intersection of lines XP and YQ will be the greatest x-coordinate that point A can have.
EquationsThe line through points (x1, y1) and (x2, y2) can be written as ...
(y2 -y1)(x -x1) -(x2 -x1)(y -y1) = 0
This equation is readily simplified to general form ax+by+c = 0.
Line XP
(-12-(-24))(x -0) -(5-0)(y -(-24)) = 0
12x -5y -120 = 0
Line YQ
(9 -25)(x -0) -(5 -0)(y -(25)) = 0
-16x -5y +125 = 0
We want the value of x that satisfies these equations. That can be found by subtracting the second equation from the first:
(12 -5y -120) -(-16x -5y +125) = (0) -(0)
28x -245 = 0
x = 245/28 = 8.75
The greatest x-coordinate is x = 8.75.
show that the convergence of a series is not affected by changing a finite number of its terms. (of course, the value of the sum may be changed.)
Convergent Series:
A Convergent Series is a series whose partial sums tend to a specific member is called a limit.
∑ 1/2n = 1/2+ 1/4 + 1/8 + 1/16 +........
Given an infinite series ∑₁ ∞ an determine the series is convergence. Recall that we can actually do better with geometric series not only we can determine convergence but also divergence. We can also calculate geometric series.
Suppose we are given a series ∑ aₙ which is not quite a geometric series but becomes a geometric series for sufficiently large n. That is we can find an integer N such that aₙ = aₓⁿ for all n > N. we don't have a general formula for aₙ when n ≤ N. The values of aₙ for small n don't effect Sₙ is convergence or not.
As a moment of fact, we never used the fact that aₙ eventually become geometric. More general ∑aₙ is convergent series, we can add a finite number of terms to the be gaining of this series or remove a finite number of terms from the be gaining of the series without affecting the convergence of the series. For Example: if ∑aₙ convergence then so does
10 + 10¹⁰ + 10 ¹⁰⁰ + 10¹⁰⁰⁰ + ∑aₙ
Similarly, if ∑aₙ convergence then,
a₁₀₀₀ +a₁₀₀₁ +a₁₀₀₂ + ..... = ∑₁₀₀₀ ∞ aₙ
However, the fact that we are only adding finitely many terms to the series is essential. That is, when it comes to determining convergence of a series ∑aₙ , we can see that only the asymptotic behavior of ∑aₙ matter, that is, only the behavior of the sequence aₙ as n--- ∞ affects convergence.

Pls help I forgot how to work out bearings
Note that because the graph is slightly deformed to the left, it is impossible to work out the exact bearing. Below, however, are steps on how to get the bearing of a map.
How do you work the bearings of a map?Calculate the angle clockwise from north to determine a bearing. Begin with the first site by drawing a vertical line symbolizing north. Draw a line from the starting point to the ending point. Calculate the clockwise angle formed by the north line and this line.
When measuring a bearing, three principles must be followed:
Always determine the angle counterclockwise.Always evaluate the angle from north to south.Always use a three-figure bearing (for example, 030° instead than 30°).Note that a bearing is an angle in degrees calculated clockwise from north in mathematics. Bearings are often specified in three figures. 30° clockwise from north, for example, is generally represented as 030°.

The price of 72 rolls of toilet rolls in each shop is:
Lidal - $25.20Oldi - $25.92The shop with the best value for money is Lidal.
How to find the price?Lidal sells 8 toilet rolls for $2.80 and so if it was to sell 72 rolls, it would sell at a price of:
= Price per 8 rolls x Number of rolls / Number of rolls in packages
= 2.80 x 72 / 8
= 2. 80 x 9
= $25.20
Oldi sells 9 toilet rolls for $3.24 so the cost of 72 rolls would be:

= $25. 92

Given systemy = 2x + 3y = - 3x + 3Solve by substitution/elimination2x + 3 = - 3x + 32x + 3x = 3 - 35x = 0x = 0y = 2*0 + 3y = 3Answer:
x = 0y = 3Step-by-step explanation:
Forming the equation,
→ 2x + 3 = -3x + 3
Now the value of x will be,
→ 2x + 3 = -3x + 3
→ 2x + 3x = 3 - 3
→ 5x = 0
→ x = 0/5
→ [ x = 0 ]
Then the value of y will be,
→ y = -3x + 3
→ y = -3(0) + 3
→ y = 0 + 3
→ [ y = 3 ]
Hence, the value of y is 3.

An element with a mass of 400 grams decays by 29.8% per minute. To the nearest
minute, how long will it be until there are 2 grams of the element remaining?
The time elapsed, to the nearest minute, until only 2 grams of the element remains is 15 minutes.
We have an element. The element has a mass of 400 grams. The element decays by 29.8% per minute. We need to find the time duration after which there will be only 2 grams of the element remaining. Let the initial mass of the element, the final mass of the element, the rate of decay, and the time elapsed be represented by the variables m, M, r, and t. We can write the equation as given below.
M = m(1 - r)^t
2 = 400(1 - 0.298)^t
0.005 = (0.702)^t
log(0.005) = t*log(0.702)
t = log(0.005)/log(0.702)
t = 14.97
