Answer:
{1, -2/5}
Step-by-step explanation:
5x^2 - 3x -2 = 0
x^2 - (3/5)x - 2/5 = 0
( x - (3/10) )^2 - (3/10)^2 - 2/5 = 0
( x - (3/10) )^2 = 2/5+9/100
( x - (3/10) )^2 = (7/10)^2
Take square roots on both sides
x - 3/10 = +/- 7/10
x = 3/10 +/- 7/10
= { 1, -2/5 }

The figure shows Triangle ABC and some of its transformed images on a coordinate grid:
A coordinate plane is shown. Triangle ABC Is formed by the points 2 commas 5, 2 comma 3, and 4 commas 3. Triangle 2 is formed by the points negative 3 commas 5, negative 3 commas 3, and negative1 comma 3. Triangle 1 is formed by the points negative 4 commas 5, negative 4 commas 3, and negative 6 commas 3. Triangle 3 is formed by the points negative 6 commas 2, negative 4 commas 2, and negative 4 commas 0. Triangle 4 is formed by the points 2 commas negative 1, 4 commas negative 1, and 4 commas negative 3.
Which of the four triangles was formed by a translation of Triangle ABC?
1
2
3
4
Answer:
Triangle 2
Step-by-step explanation:
The translation is a type of transformation, where the figure is just translated or simply moved from its original place.
The figure is not rotated or dilated but simply moved.
Here, we can see that only figure or triangle 2 is like the triangle ABC. Other triangles have undergone other transformations.
So, the correct answer is triangle 2.

Plss help I don't understand A circle has a diameter that extends from (2,6) to (-6,-8). What are the coordinates the
center of the circle
Answer:
(-2, -1)
Step-by-step explanation:
The centre of a circle is located at the mid-point of any diameter, hence we take the average of the coordinates of the end-points.
Cx = (2-6)/2 = -2
Cy = (6-8)/2 = -1
So the centre is located at (-2, -1)

Lorelei needs to find the distance across a lake. She locates two points on opposite sides of the lake, then walks a straight line from each point to a spot south of the lake. The path on one side is 444 feet long, while the other path is 552 feet long. The two paths meet at an angle of 68 degrees. find the distance across the lake to the nearest foot.
Answer:
564 ftStep-by-step explanation:
We have two sides of the triangle and the included angle and we need to find the missing side.
Use the law of cosines:
[tex]c = \sqrt{a^2+b^2-2ab*cos C}[/tex][tex]c = \sqrt{444^2+552^2-2*444*552*cos (68)}[/tex] ≈ 564 ftis -cos(x) the same as cos(-x)?

Answers:
[tex]x = 5\sqrt{3}[/tex]
[tex]y = 10[/tex]
==================================================
Explanation:
This is a 30-60-90 triangle. The short leg 5 is opposite the smallest angle 30 degrees.
The long leg is sqrt(3) times that of the short leg, which explains why x = 5*sqrt(3).
The hypotenuse is twice as long compared the short leg, so y = 2*5 = 10.
You could use trig ratios and the unit circle as another way to find x and y.

Answer:
(a) x = [tex]128^{o}[/tex]
(b) x = [tex]74^{o}[/tex]
Step-by-step explanation:
A. sum of angles in a polygon = (n - 2) 180
The polygon given is an irregular pentagon, where n = 5
So that;
sum of angles in a pentagon = (5 - 2) 180
= 3 x 180
= [tex]540^{o}[/tex]
Thus,
x + 90 + 76 + 110 + 136 = [tex]540^{o}[/tex]
x + 412 = [tex]540^{o}[/tex]
x = [tex]540^{o}[/tex] - 412
x = [tex]128^{o}[/tex]
B. The polygon given is an irregular pentagon, where n = 5.
Let the supplementary angle with angle 38 be represented by y,
y + 38 = 180
y = 180 - 38
= [tex]142^{o}[/tex]
y = [tex]142^{o}[/tex]
Let the supplementary angle with x be represented by z, so that;
z + 72 + 120 + 100 + 142 = [tex]540^{o}[/tex]
z + 434 = [tex]540^{o}[/tex]
z = [tex]540^{o}[/tex] - 434
= [tex]106^{o}[/tex]
z = [tex]106^{o}[/tex]
But, x + z = [tex]180^{o}[/tex]
Then;
x + [tex]106^{o}[/tex] = [tex]180^{o}[/tex]
x = [tex]180^{o}[/tex] - [tex]106^{o}[/tex]
= [tex]74^{o}[/tex]
x = [tex]74^{o}[/tex]

Step-by-step explanation:
The height of a triangle is 2 less than 3 times it's base. If the area of the triangle is 48cm squares determine the base and height?
we assume the height of the triangle is x,
so the base length will be x+4
the triangle area will be area = 1/2 ( base * height)
48 = 1/2 (x + 4) x
96 = x2 + 4x
96 + 4 = x2 + 4x + 4
100 = (x + 2)2
10 = x + 2 (for the square 100, we ignore the -10, minus is meaningless in length )
x = 8
x + 4 = 8 + 4 = 12
so the height for the triangle is 8 unit, base is 12 unit,

You spin a spinner with 9 equal spaces numbered 1 through 9. What is the probability that the spinner lands on a 5 or a multiple of 3? I HAVE 5 MINS
Answer:
4/9
Step-by-step explanation:
The probability that the spinner lands on a 5 or a multiple of 3 will be 0.4444 or 44.44%.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
You spin a spinner with 9 equal spaces numbered 1 through 9.
Then the probability that the spinner lands on a 5 or a multiple of 3 will be
The total number of the event will be
Total events = 9
The favorable event will be
Favorable = 1 {5} and 3 {3, 6, 9}
Then the probability will be
P = 1/ 9 + 3/ 9
P = (1 + 3) / 9
P = 4/9
P = 0.4444
P = 44.44%

Assuming that there are only 2 flavors of the sweet ⇻ strawberry & orange.
____________________
P (strawberry flavored sweet) = 0.8
P (orange flavored sweet) = ?

Part one answers $7.50, $5.00,$1.50
Part two answers $17.50,$15.50,$15.00
Answer:
Joe Will need to pay a commission of [$7.50]. The Total amount Charged by the broker will be [$17.50]
Step-by-step explanation:
Joe will need to pay a commission of [tex]\$7.50[/tex] and Total amount charged by broker will be [tex]\$17.50[/tex].
What is commission ?Commission is a form of money pay as remuneration for services rendered or products sold.
A.We have,
Joe's current portfolio [tex]=\$ 50,000[/tex]
Price of one stock [tex]=\$15[/tex]
So,
As his portfolio is less than [tex]\$100,000[/tex], he have to pay [tex]15\%[/tex] and [tex]\$10[/tex] trade fee,
So,
Price of [tex]50[/tex] shares [tex]=50*15=\$750[/tex]
Commission charge [tex]=1\%\ of\ 750[/tex]
[tex]=\$7.5[/tex]
So, commission of [tex]\$7.5[/tex] will be paid.
B.So,
Total amount charged by Broker [tex]=10+7.5=\$17.5[/tex]
Hence, we can say that Joe will need to pay a commission of [tex]\$7.50[/tex] and Total amount charged by broker will be [tex]\$17.50[/tex]. .
