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

Therefore, the he equation of line for [tex]x[/tex] is [tex]2[/tex].

What is the equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here given that

Celinda scored two more than three times as many strikes as Teresa did while they were bowling. Celinda scored eight strikes. Let x represent the number of strikes Teresa scored.

[tex]8-2=6\\\\\frac{6}{3}=2[/tex]

Hence, the equation for [tex]x[/tex] is [tex]2[/tex].

Answer:

C

Step-by-step explanation:

The angle QPR must be congruent to the angle SPT.

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.

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.

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]

Answer:

The side lengths can not form a triangle

Step-by-step explanation:

Given

[tex]Sides: 23,16,7[/tex]

Required

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]39 > 7[/tex] --- True

[tex]23 + 7 > 16[/tex]

[tex]30 > 16[/tex] --- True

[tex]16 + 7 > 23[/tex]

[tex]23 > 23[/tex] --- False

Hence, the side lengths can not form a triangle

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.

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]

Step-by-step explanation:

Let x be the smallest even integer.

Then (x + 2) and (x + 4) are the other even integers.

We have x + (x + 2) + (x + 4) = 138.

=> 3x + 6 = 138

=> 3x = 132

=> x = 44.

Hence the smallest integer is 44.

Convert these mixed fractions to improper fractions.

3 3/5 = 18/5

-8 1/3 = -25/3

Now, it is easier to multiply them. Multiply the numerators and the denominators.

18  x   25   =   450

5          3           15

Simplify the final answer by dividing 450 ÷ 15, which is 30.
