g Find the equation of the line passing through the point (1, 1, 1) which is perpendicular to the plane containing the points (1, 0, 0), (2, 1, 1) and (1, 1, 2).
Answer:
The equation of the line is given by:
[tex]x = 1 + t[/tex]
[tex]y = 1 - 2t[/tex]
[tex]z = 1 + t[/tex]
Step-by-step explanation:
Parametrizing the equation of the line in function of t, the equation of the line is given by:
[tex]x = x_0 + at[/tex]
[tex]y = y_0 + bt[/tex]
[tex]z = z_0 + ct[/tex]
In which we have an initial point [tex](x_0,y_0,z_0)[/tex] and [tex](a,b,c)[/tex] is a vector parallel to the line.
Line passing through the point (1, 1, 1)
This means that [tex]x_0 = y_0 = z_0 = 1[/tex]. So
[tex]x = 1 + at[/tex]
[tex]y = 1 + bt[/tex]
[tex]z = 1 + ct[/tex]
Perpendicular to the plane containing the points (1, 0, 0), (2, 1, 1) and (1, 1, 2).
From this, we get two vectors:
[tex](2-1,1-0,1-0) = (1,1,1)[/tex]
[tex](1-2,1-1,2-1) = (-1,0,1)[/tex]
The parallel vector is given by the determinant of the following matrix:
[tex]\left[\begin{array}{ccc}i&j&k\\1&1&1\\-1&0&1\end{array}\right][/tex]
Which is:
[tex]D = i*1*1 + j*1*-1 + k*1*0 - k*1*(-1) - j*1*1 -i*1*0[/tex]
[tex]D = i - j + k - j[/tex]
[tex]D = i - 2j + k[/tex]
So the vector is (1,-2,1), and the equation of the line is:
[tex]x = 1 + t[/tex]
[tex]y = 1 - 2t[/tex]
[tex]z = 1 + t[/tex]

What is the x-intercept of the graph below?
Answer:
[tex] \huge \boxed { - 3}[/tex]
Step-by-step explanation:
The graph intercepts x-axis at (-3,0). Therefore x-intercept is - 3.
To find the x-intercept from graph, look where does the graph intercept x-axis at, and that is x-intercept. If the graph doesn't intercept of pass x-axis then there's no x-intercept.

Write the expressions for (s-t)(x) and (s+t)(x) and evaluate (s⋅t)(-1)
Answer:
(s-t)(-1) = -1
(s+t)(-1) = -7
Step-by-step explanation:
Given the following set of functions
s(x)=2x-2
t(x)=3x
(s-t)(x) = s(t) - t(x)
(s-t)(x) = 2x - 2 - 3x
(s-t)(x) = -x -2
(s-t)(-1) = -(-1) - 2
(s-t)(-1) = 1-2
(s-t)(-1) = -1
(s+t)(x) = s(t) + t(x)
(s+t)(x) = 2x - 2 + 3x
(s+t)(x) = 5x -2
(s+t)(-1) = 5(-1) - 2
(s+t)(-1) = -5-2
(s+t)(-1) = -7

At noon, a barista notices she has $20 in her tip jar. If she makes an average of $0.50 from each customer, how much will she have in her tip jar if she serves n more customers during her shift
Answer:
She has $20 + $0.50n in her tip jar.
Step-by-step explanation:
Amount in tip jar at noon = $20
Average amount made from each customer = $0.50
Number of additional customers served after noon = n
Therefore, we have:
Additional amount made after noon = Average amount made from each customer * Number of additional customers served after noon = $0.50 * n = $0.50n
Amount in tip jar = Amount in tip jar at noon + Additional amount made after noon = $20 + $0.50n
Therefore, she has $20 + $0.50n in her tip jar.

D.
a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 3
Answer:
a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 2
Step-by-step explanation:
At Image I, we have vertex at point (3,-2), and the length of the left side is of 1 unit(from -2 to -3).
In the larger figure, this length is of 2 units, so the dilation has a scale factor of 2 units. The rotation, due to the coordinates changing, is of 90º counterclockwise(if it was across the x-axis, only the y coordinate would change, but on image II, both coordinates change).
So the correct answer is:
a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 2

By what factor is z multiplied to get z1?
Answer:
The correct answer is -2.
Step-by-step explanation:
"z" = 3+2i, which is (3, 2i) on the graph. You must multiply -2 by 3 and 6, which will give you the plot points for z1, (-6, -4i).
A negative number multiplied into a positive number will result in a negative number.
Therefore, -2 is the correct answer.

Can the side lengths can form a triangle?
To do this, we apply triangle Inequality Theorem, which states that for sides a, b and c:
[tex]a + b>c[/tex] , [tex]c + b>a[/tex] and [tex]c + a>b[/tex]
In this case, we have:
[tex]23 + 16 > 7[/tex]

[tex]23 + 7 > 16[/tex]
[tex]30 > 16[/tex] --- True
[tex]16 + 7 > 23[/tex]

A. AQPR must be a right triangle.
B. AQPR must be congruent to AQRS.
C. AQPR must be congruent to AQPT.
D. AQPR must be congruent to ASPT.
Answer:
C
Step-by-step explanation:
The angle QPR must be congruent to the angle SPT.
What is meant by congruent?The congruent means the same shape and size.
Given that in a rectangle QRST, diagonals QS and RT are drawn and intersect at point P.
Since two sides are equal, it obey congruence theorem.
Consider the two congruence triangle, triangle QPR and triangle SPT.
Hence, angle QPR and angle SPT are the two congruence angle.

Suppose h(x) = ax^3 + 11x^2. Determine a if h has an inflection point at x = 4. Show all your work.
Answer:
[tex]a=-11/12[/tex]
Step-by-step explanation:
We are given the function:
[tex]h(x)=ax^3 + 11 x^ 2[/tex]
And we want to determine a such that h(x) has an inflection point at x = 4.
Possible inflection points are whenever h''(x) equals 0. So, we will first differentiate h(x) twice. This yields:
[tex]h'(x)=3ax^2+22x[/tex]
So:
[tex]h^{\prime\prime} (x)=6ax+22[/tex]
Inflection points occur when h''(x) = 0. So:
[tex]0=6ax+22[/tex]
Since we have an inflection at x = 4:
[tex]0=24a+22[/tex]
And solving for a yields:
[tex]a=-22/24=-11/12[/tex]

This isn't the answer, but do you have the rest of the questions?
