the equation for line p can be written as y = -1/2x+8. Line q, which is perpendicular to line p, includes the point (4,7). what is the equation of line q
Answer:
y = 2m -1
Step-by-step explanation:
y = mx + b is the slope intercept form of a line.
Perpendicular slopes are opposite reciprocals of each other. That means that you flip the fraction and take the opposite sign. The slope will be 2.
Now us the slope, the x value and the y value from the give point to find the y-intecept (b)
Slope = 2 (m)
y = 7 from the point (4,7)
x = 4 from th point (4,7)
y = mx + b
7 = 2(4) + b
7 = 8 + b Subtract 8 from both sides
-1 = b
y = 2x - 1

Answer:
[tex]\textsf{1.} \quad (x-1)^2=12(y+2)[/tex]
See attachment 1.
2. See attachment 2.
Step-by-step explanation:
Question 1Given values:
Vertex: (1, -2)Focus: (1, 1)As the x-value of the vertex and focus is the same, the parabola has a vertical axis of symmetry.
The focus is always on the inside of the parabola.
Since p represents the distance from the vertex to the focus, and the distance from the vertex to the focus is 1 - (-2) = 3, then p = 3.
If p > 0, the parabola opens upwards, and if p < 0, the parabola opens downwards. Therefore, as p > 0, the parabola opens upwards.
[tex]\boxed{\begin{minipage}{5.8 cm}\underline{Standard form of a parabola}\\(with a vertical axis of symmetry)\\\\$(x-h)^2=4p(y-k)$\\\\where:\\ \phantom{ww}$\bullet$ $p\neq 0$\\ \phantom{ww}$\bullet$ Vertex: \;$(h,k)$\\ \phantom{ww}$\bullet$ Focus:\; $(h,k+p)$\\ \phantom{ww}$\bullet$ Directrix: \; $y=(k-p)$\\ \phantom{ww}$\bullet$ Axis of symmetry: \; $x=h$\\\end{minipage}}[/tex]
Therefore:
h = 1k = -2p = 3Substitute the values into the formula:
[tex]\implies (x-h)^2=4p(y-k)[/tex]
[tex]\implies (x-1)^2=4\cdot 3(y-(-2))[/tex]
[tex]\implies (x-1)^2=12(y+2)[/tex]
See attachment 1 for the graph of the parabola.
Question 2Given equation of a parabola:
[tex](y-4)^2=8(x+2)[/tex]
As the y-variable is contained within the squared part of the equation, the parabola has a horizontal axis of symmetry.
[tex]\boxed{\begin{minipage}{5.8 cm}\underline{Standard form of a parabola}\\(with a horizontal axis of symmetry)\\\\$(y-k)^2=4p(x-h)$\\\\where:\\ \phantom{ww}$\bullet$ $p\neq 0$\\ \phantom{ww}$\bullet$ Vertex: \;$(h,k)$\\ \phantom{ww}$\bullet$ Focus:\; $(h+p,k)$\\ \phantom{ww}$\bullet$ Directrix: \; $x=(h-p)$\\ \phantom{ww}$\bullet$ Axis of symmetry: \; $y=k$\\\end{minipage}}[/tex]
Therefore:
h = -2k = 44p = 8 ⇒ p = 2If p > 0, the parabola opens to the right, and if p < 0, the parabola opens to the left. Therefore, as p > 0, the parabola opens to the right.
Find the y-intercepts of the graph by substituting x = 0 into the equation:
[tex]\implies (y-4)^2=8(0+2)[/tex]
[tex]\implies (y-4)^2=16[/tex]
[tex]\implies y-4=\pm4[/tex]
[tex]\implies y=4\pm4[/tex]
[tex]\implies y=0, y=8[/tex]
To sketch the graph of the parabola, plot:
Vertex = (-2, 4)Focus = (0, 4)Axis of symmetry: y = 4y-intercepts: (0, 0) and (0, 8)Draw a curve through the vertex and y-intercepts, opening to the right.
Use the axis of symmetry to ensure the curve is symmetric.

a) Determine an exact value for cosx.
b) Determine an exact value for siny.
sin y =12/13 but can't find cos x as sin x can't exceed from 1.
It can be solved by using identities of trigonometry.
What are the trigonometric identities?
These are the equivalent ways to define trigonometric functions.
Basic identities are:
sin²x + cos²x = 1
1 + tan²x = sec²x
1 + cot²x = cosec²x
For cos x:
cos²x = 1 - sin²x
= 1 - (5/3)²
= 1- (25/9)
= -16/9
i.e. not possible
For sin y:
sin²y = 1 - cos²y
= 1 - (5/13)²
= 1 - 25/169
= 144/169
So, sin y = ±(12/13)
but as mentioned x and y are in 1st quadrant ,
so, sin y = 12/13.

$ 1.31 should pay for the chance to win if it is a fair game.
Probability is simply how likely something is to happen.
Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
It is a fair game if what we gain equals what we stake.
There are 13 clubs in a standard deck of 52 cards.
Probability of 3 clubs = 13C3 / 52C3 = 286/22100 = 0.01294
For a fair game,
$100(0.01294) = x(1-0.01294)

The pair of triangles can be proved to be congruent using the ASA postulate of congruency.
In the two triangles , let the first right angled triangle be ABC and the second right angled triangle be DEF.
In ΔABC and ΔDEF
∠ABC = 90° and ∠DEF = 90°
∠ACB = ∠DFE
therefore by using the angle sum property of the triangle we can say that:
∠CAB = ∠FDE
Therefore in the pair of triangles: ΔABC and ΔDEF we have :
∠ACB = ∠DFE
∠CAB = ∠FDE
AC = DF is given which is also the common side to both the angles.
Hence we can say
ΔABC ≅ ΔDEF ( By angle-side -angle postulate of congruency)

Given,
Number of random sample selected, n = 6967
Number of surveys returned, x = 1331
Estimated proportion of return rate;
p = 1331/6967 = 0.192
Significance level, ∝ = 0.01
z would represent the statistic
We investigate the assertion that the return rate is less than 20%, and the following hypotheses are tested:
Null hypothesis, p₀ ≥ 0.2
Alternative hypothesis, p₀ < 0.2

That is,
z = (0.191 - 0.2) / √(0.2(1 - 0.2)/6967) = -1.878
Using the alternative hypothesis and the following probability, we can now get the p value:
p value = p(z < - 1.878) = 0.0302
