Answer:
A. 0.72
Step-by-step explanation:
We take the amount spent on the necklaces and divide that by the amount she bought. So that would be $11.52/8. When we divide this, we get 1.44, and since this is not an option, I went and divided it by the two friends to get 0.72. So I believe A. would be the answer.
The cost for each necklace is given as $0.72.
How to calculate the cost per item?In order to calculate the cost of one item, divide the total cost of items by the total number of items.
It is also called the unit rate of that item.
Total money spent on 8 neckless is $11.52.
The number of friends Rosa has 2.
Then, total number of necklaces is 8 × 2 = 16
Now, the cost of each necklace can be calculated as,
Total cost of necklace ÷ Number of necklace
= $11.52 ÷ 16
= $0.72
Hence, the cost of each necklace for each of the friends is $0.72.

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.
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]

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

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
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]

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]

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.
