Triangle ABC has vertices at A(−3, 3), B(0, 7), and C(−3, 0). Determine the coordinates of the vertices for the image if the preimage is translated 3 units up.
A′(−3, 0), B′(0, 4), C′(−3, −3)
A′(−3, 6), B′(0, 10), C′(−3, 3)
A′(−6, 3), B′(−3, 7), C′(0, 0)
A′(0, 3), B′(3, 5), C′(0, 0)
Answer:
To translate triangle ABC 3 units up, we need to add 3 to the y-coordinate of each vertex:
A' = (-3, 3 + 3) = (-3, 6)
B' = (0, 7 + 3) = (0, 10)
C' = (-3, 0 + 3) = (-3, 3)
Therefore, the coordinates of the vertices for the image triangle A'B'C' are A'(-3, 6), B'(0, 10), and C'(-3, 3).
So the correct answer is: A′(−3, 6), B′(0, 10), C′(−3, 3).

A Circle has a radius of 6cm, an arc AB of the circle is 9cm calculate this angle subtended by AB
The angle subtended by the arc AB in the circle is 68.75 degrees.
We have,
We know that the circumference of a circle is given by 2πr,
where r is the radius of the circle.
The circumference of the circle with a radius of 6 cm is.
C = 2πr = 2π(6) = 12π cm
Since the arc AB of the circle is 9 cm, we can find the angle subtended by this arc using the formula:
angle = (arc length / circumference) x 360°
Plugging in the values we have:
angle = (9 / 12π) x 360°

SOMEONE PLEAS HELP!
Answer:
The answer to your problem is, A. 5/2 and 25/4
Step-by-step explanation:
In the problem the two similar figures, with side lengths 30 yds and 12 yds.
In order to solve the problem we need to find the ratio of the perimeters and the ratio of the areas of the larger figure to the smaller figure.
Using this information we know the the ratio of the perimeter of similar figure is equal to the scale factor and the ratio of the areas equal to the square of the scale factor.
the scale factor = 30/12 = 5/2
the ratio of the perimeter = 5/2
the ratio of the areas = (5/2)² = 25/4
Thus the answer to your problem is, A. 5/2 and 25/4

(e) The selling price per share = $35.65
(f) Capital Gain = $3022.5
(g) Purchase price per share = $29
(h) Percent of capital loss = 20.7%
(i) Purchase price per share $54 and selling price per share $62.
The number of shares is 500.
So, Capital Gain = (500*62 - 500*54) = $4000
Percent of Capital Gain = (4000/(500*54))*100% = 14.8% (rounding to nearest tenth)
(ii) Number of shares = 100 and selling price of per share = $12 and capital gross = $700.
Purchase price per share = (12*100 - 700)/100 = 500/100 = $5
So the percent of capital gain = (700/(5*100))*100% = 140%
(iii) Number of shares = 650 and purchasing price per share = $31 and percent of capital gain = 15%
The selling price per share = 31*(100+15)/100 = $35.65
Capital Gain = (31*650)*15% = $3022.5
(iv) Number of shares = 1300 and selling price of per share = $23 and capital loss = - $7800

Hence, (a) $4000; (b) 14.8% (gain); (c) $5; (d) 140% (gain); (e) $35.65; (f) $3022.5; (g) $29; (h) 20.7% (loss).

Peter’s teacher says he may have his report card percentage based on either the mean or the median and he can drop one test score if he chooses.
84%, 71%, 64%, 90%, 75%, 44%, 98%
Which measure of center should Peter choose so he can have the highest percentage possible?
Peter should choose the mean after dropping one test score.
Peter should choose the mean without dropping one test score.
Peter should choose the median after dropping one test score.
Peter should choose the median without dropping one test score.
Answer:
A.
Step-by-step explanation:
Peter should choose to base his report card percentage on the median if he wants to have the highest percentage possible. To calculate the median, Peter would first order the scores from lowest to highest: 44%, 64%, 71%, 75%, 84%, 90%, 98%. Then, he would select the middle score as the median, which is 75%. If Peter drops his lowest score (44%), his percentage based on the median would be 80% ((64%+71%+75%+84%+90%+98%)/6). If he were to choose the mean, his percentage would also be 80%. However, since the median is not affected by extreme values like the 44% score, it is a more reliable measure of central tendency in this case.
I did this on homework b4 and got It right so this Is 100 percent right.
Answer:
Peter should choose the median after dropping one test score so he can have the highest percentage possible.
If we calculate the mean of all seven test scores, we get:
(84+71+64+90+75+44+98)/7 = 73.14%
If we calculate the median of all seven test scores, we get:
Arrange the scores in ascending order:
44, 64, 71, 75, 84, 90, 98
The median is 75.
If we drop the lowest score (44) and calculate the mean of the remaining six test scores, we get:
(84+71+64+90+75+98)/6 = 80.5%
If we drop the lowest score (44) and calculate the median of the remaining six test scores, we get:
Arrange the scores in ascending order:
64, 71, 75, 84, 90, 98
The median is 79.5%.
Therefore, Peter should choose the median after dropping one test score to have the highest possible percentage.

Step-by-step explanation:
To solve for x in the equation [tex]3x - 3 = 4(x - 9)[/tex], we will follow these steps:
1. Distribute the 4 on the right-hand side of the equation:
[tex]3x - 3 = 4x - 36[/tex]2. To isolate x, subtract 3x from both sides:

Find the minimum and maximum values of the objective function, and the points at which these values occur subject to the given constraints. Round your answers to the
nearest hundredth.
The minimum value of the objective function is 47, which occurs at the point (3,2), and the maximum value is 117, which occurs at the point (0,9).
To solve this linear programming problem, we need to first graph the feasible region defined by the given constraints:
The first constraint, x ≥ 0, represents the non-negative values of x along the x-axis.
The second constraint, 4x + 8y ≥ 32, can be rewritten as y ≥ -(1/2)x + 4, which is a line with a y-intercept of 4 and a slope of -(1/2). The feasible region is above this line.
The third constraint, 10x - y ≤ 30, can be rewritten as y ≥ 10x - 30, which is a line with a y-intercept of -30 and a slope of 10. The feasible region is above this line as well.
The fourth constraint, x + 6y ≤ 54, can be rewritten as y ≤ -(1/6)x + 9, which is a line with a y-intercept of 9 and a slope of -(1/6). The feasible region is below this line.
The feasible region is therefore the polygon bounded by the lines y = -(1/2)x + 4, y = 10x - 30, y = -(1/6)x + 9, and x = 0. To find the minimum and maximum values of the objective function f(x,y) = 11x + 13y, we need to evaluate this function at each corner of the feasible region and compare the results.
The corners of the feasible region are (0,4), (3,2), (5,4), and (0,9). Evaluating the objective function at these corners, we get:
f(0,4) = 52
f(3,2) = 47
f(5,4) = 89
f(0,9) = 117
Therefore, the minimum value of the objective function is 47, which occurs at the point (3,2), and the maximum value is 117, which occurs at the point (0,9).

The solution of "quadratic-equation" , 3x² - 6x + 2 = 0 is (b) x = (3 ± √3)/3.
A "Quadratic-Equation" is defined as a second-degree polynomial equation of the form : ax² + bx + c = 0,
where x = variable, and "a", "b", and "c" are constants, with a ≠ 0.
We use the "quadratic-formula" to solve : which is ⇒ x = (-b ± √(b²-4ac))/(2a),
In the quadratic equation "3x² - 6x + 2 = 0", We get , a = 3, b = -6, and c = 2.
Substituting the values,
we get,
⇒ x = (-(-6) ± √((-6)²-4(3)(2)))/(2×3),
⇒ x = (6 ± √(36-24))/6,
⇒ x = (6 ± √12)/6,
⇒ x = (6 ± 2√3)/6,

27). What is the scale factor of Δ EFG to Δ HIJ?
28). What is the ratio of their perimeters?
29). What is the ratio of their areas?
The triangles are not congruent.
Given that, two triangles, EFG and HIJ are similar,
So,
Since, the triangles are similar, but according to the definition of similarity, two objects that are similar are not necessarily congruent,
so the Δ EFG is not congruent to Δ HIJ.
Cos 30° = HI / HJ
√3/2 = 3/HI
HI = 3.5
Therefore, the scale factor Δ EFG to Δ HIJ = EF / HI = 10/3.5 = 2/0.7
The ratio of perimeter of similar objects are same as the scale factor,
so, the ratio of their perimeters = 2/0.7
The ratio of the areas of the similar objects are the ratios of the squares of the scale factor.
So, the ratio of their areas = 4/0.49

What is an equation of the line that passes through the points (0,-8) and (4, -3)?
=00
Hello!
To find the equation of the line that passes through the points (0,-8) and (4,-3), we can use the slope-intercept form of the equation:
y = mx + b
where m is the slope of the line and b is the y-intercept.
First, find the slope (m) of the line using the formula:
m = (y2 - y1)/(x2 - x1)
where (x1, y1) = (0,-8) and (x2, y2) = (4,-3).
m = (-3 - (-8))/(4 - 0) = 5/4
Now that we have the slope (m), we can use the point-slope form of the equation to find the equation of the line:
y - y1 = m(x - x1)
where (x1, y1) = (0,-8) and m = 5/4.
y - (-8) = (5/4)(x - 0)
Simplify the equation to get the slope-intercept form:
y + 8 = (5/4)x
y = (5/4)x - 8
Therefore, the equation of the line that passes through the points (0,-8) and (4,-3) is y = (5/4)x - 8.
