Answer:
16. a: (-90°, (4, 3)); b: (90°, (0, 3)); c: (-90°, (0, 0))
17. a: (down, (4, -1)); b: (right, (4, 3)); c: (up, (5, 2))
Step-by-step explanation:
We don't know what notation you're used to seeing for rotations. Here. we'll use the form [degrees CCW, (center)]. (CW angles are negative.) In any rotation, the center is the point that is invariant (remains in the same place)
16.
a) The tail is invariant, so the rotation is (-90°, (4, 3)).
b) The tip is invariant, so the rotation is (90°, (0, 3)).
c) The origin is invariant, so the rotation is (-90°, (0, 0))
__
17.
a) The tail is invariant, so the arrow is pointing down with the tip at (4, -1).
b) The center is invariant, so the arrow is reversed. It is pointing right with the tip at (4, 3).
c) Point (2, 3) is invariant, so the arrow is pointing up with the center at (5, 0). The tip is at (5, 2).
_____
Additional comment
If you have trouble visualizing these rotations, you might find it useful to trace the arrow on a piece of (semi-)transparent medium (plastic or tracing paper) so that you can move it as required to match the descriptions in the problem statement. A pin, or a dot on your tracing, can serve to fix the center of rotation. A little hands-on never hurts in math and geometry.

Ms. Fry started walking as her New Year's resolution. She calculated that she can walk ½ mile in ¼ of an hour. What is her walking rate in miles per hour?
Answer:
the walking rate miles per hour is 2 miles per hour
Step-by-step explanation:
The computation of the walking rate miles per hour is shown below;
Given that
She can walk half mile in one-fourth of an hour
= Miles ÷ hours
= (1÷ 2) ÷ (1 ÷4)
= 0.50 ÷ 0.25
= 2 miles per hour
Hence, the walking rate miles per hour is 2 miles per hour

PLEASE HELP WITH THE FIRST 3 parts
Answer:
a) x = -2+√3 and -2-√3
b) x = -1 + 2√3/3 and -1 - 2√3/3
c) x = 3.185 and 0.315
Step-by-step explanation:
To solve the following quadratic equation, we will use the general formula
x = -b±√b²-4ac/2a
a) x²+4x+1 = 0
a = 1, b = 4 and c = 1
Substitute into the formula
x = -4±√4²-4(1)(1)/2(1)
x = -4±√16-4/2
x = -4±√12/2
x = -4±2√3/2
x = (-4+2√3)/2 and (-4-2√3)/2
x = -2+√3 and -2-√3
b) 3x²+6x-1 = 0
a = 3, b = 6 and c = -1
Substitute into the formula
x = -6±√6²-4(3)(-1)/2(3)
x = -6±√36+12/6
x = -6±√48/6
x = -6±4√3/6
x = (-6+4√3)/6 and (-6-4√3)/6
x = -1 + 2√3/3 and -1 - 2√3/3
c) 2x² - 7x + 2 = 0
a = 2, b = -7 and c = 2
x = -(-7)±√(-7)²-4(2)(2)/2(2)
x = 7±√49-16/4
x =7±√33/4
x = 7±5.74/4
x = 7+5.74/4 and 7-5.74/4
x = 12.74/4 and 1.26/4
x = 3.185 and 0.315
Use intercepts to graph the linear equation -2x+7y=-21 Question 2
Identify the points corresponding to the intercepts
Answer:
The point representing the y-intercept is: (0, -3)
The black dot represents the y-intercept on the attached graph. It is very clear at y = 0, x = -3.
The point representing the x-intercept is: (10.5, 0)
The red dot represents the x-intercept on the attached graph. It is very clear at x = 0, y = 10.5
Step-by-step explanation:
Given the linear equation
-2x+7y=-21
Determining the y-intercept
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
substituting x = 0 in the equation
-2x+7y=-21
-2(0) + 7y = -21
0+7y = -21
7y = -21
divide both sides by 7
7y/7 = -21/7
y = -3
Therefore, the point representing the y-intercept is: (0, -3)
The black dot represents the y-intercept on the attached graph. It is very clear at y = 0, x = -3.
Determining the x-intercept
We know that the value of x-intercept can be determined by setting y = 0, and determining the corresponding value of x.
substituting y = 0 in the equation
-2x+7y=-21
-2x+7(0) = -21
-2x + 0 = -21
-2x = -21
divide both sides by -2
-2x / -2 = -21 / -2
x = 21/2
x = 10.5
Therefore, the point representing the x-intercept is: (10.5, 0)
The graph of the linear equation containing the y-intercept (0, -3) and x-intercept (10.5, 0) is shown and attached below.
The red dot represents the x-intercept on the attached graph. It is very clear at x = 0, y = 10.5

7 qt. of a 27% saline solution was mixed
with 3 qt. of a 17% saline solution. What
is the concentration of the mixture?
Answer:
24% saline
Step-by-step explanation:
Find how much saline is in both solutions:
7(0.27)
= 1.89
3(0.17)
= 0.51
Add this together:
1.89 + 0.51
= 2.4
Since there are 10 quarts in total, the concentration of the mixture can be found by dividing 2.4 by 10:
2.4/10
= 0.24
So, the concentration of the mixture is 24% saline
please help me before i fail!! Find the solution(s) of the following equation.
c^2 = 144/169
Choose all answers that apply:
A) c = 12/13
B) c = -12/13
C) c = 14/15
D) c = -14/15
E) None of the above
Answer: A or B but really A
Step-by-step explanation:
c² = 144/169
√c² = √144/169
c = 12/13
or
-12/13² = 144/169
Hope that helped! I recommend choosing A
The solutions to the equation c² = 144/169 are c = 12/13 and c = -12/13, as they satisfy the equation when substituted into it. Thus, options A and B are the correct answers.
The equation is given as follows:
c² = 144/169
To find the solutions of the equation c² = 144/169, we can take the square root of both sides of the equation.
√(c² = ±√(144/169)
Since the square root of a number can be positive or negative, we have two possibilities for the solutions:
c = ±√(144/169)
Simplifying the square root of 144/169 gives:
c = ±(12/13)
So, the solutions to the equation are:
A) c = 12/13
B) c = -12/13
Therefore, options A and B are the correct answers.

Given coordinates T(10,18) and the midpoint of segment ST at (5,-8), what are the coordinates of point S?
Answer:
S = (-4, -34)
Step-by-step explanation:
T=(10, 18) is one end of the segment
the midpoint is located at (5, -8)
therefore, using the formula for midpoint, we can find the other end of the segment (point S)
Midpoint x-value = xa + (xb - xa)/2
in our case;
5 = 10 + (xb-10)/2
3 - 10 = (xb-10)/2
-7 = (xb-10)/2
-14 = xb-10
xb = -14 + 10 = - 4
Now for the y value of the midpoint:
Midpoint y-value = ya + (yb - ya)/2
in our case:
-8 = 18 + (yb - 18)/2
- 26 = (yb - 18)/2
- 52 = yb - 18
yb = -52 + 18 = -34
Then. point S is located at: S = (-4, -34)
Answer: (0, -34)
Step-by-step explanation:
[tex]M(5,-8)=(\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2})\\(5,-8)(\frac{10 + x_{2} }{2} ,\frac{18 + y_{2} }{2})[/tex]
[tex]5=(\frac{10 +x_{2} }{2})\\ 10=10+x_{2} \\-10-10\\0 = x_{2}\\x_{2} =0[/tex] [tex]-8=(\frac{18 +y_{2} }{2})\\ -16=18+y_{2} \\-18-18\\-34 = y_{2}\\y_{2} =-34[/tex]

Minha says triangle A with angles measuring 34 ° and 57 ° is similar to triangle B with angles measuring 57 ° and 89 ° . What Minha said is correct, but why is she correct?
A. Minha is correct because each triangle has an angle measuring 57 °
B. Minha is correct because 180 - (34 + 57) = 89
which means two angles in triangle A are congruent to two angles in triangle B
Answer:
b

how do i reflect over the y-axis if one point is over the y-axis?
Answer:
Coordinates of point B':
B' = (-1, -4)
Explanation
To reflect a point or a figure across the x-axis we use the rule:
→
In other words, we multiply the y-coordinate of our points by -1, while leaving the original x-coordinate as it is.
Let's apply the rule to every point of our triangle :
A = (2, 1)
A' = (2, 1*-1) = (2, -1)
B = (-1, 4)
B' = (-1, 4*-1) = (-1, -4)
C = (3, 7)
C' = (3, 7*-1) = (3, -7)

find the measure of the missing angle
Step-by-step explanation:
given
as it is right angled triangle so
Let the unknown angle be x Then
90° + 40° + x = 180° ( being sum of angles of triangle)
130° + x = 180°
x = 180° - 130°
Therefore x = 50°
Hope it will help you :)❤
Answer:
The other angle will be 50°.
Step-by-step explanation:
Given that the diagram shows a right angle triangle (90°) and the total sum of angles of a triangle is 180°. In order to find the other angle, you have to subtract :
x + 40° + 90° = 180°
x + 130° = 180°
x = 180° - 130°
x = 50°
The Garcia family started the day with 222 gallons of milk. They drank 111 quart of milk for breakfast and 3 pints for lunch. How many pints of milk did the Garcia family have left after lunch?
Answer:
11 pints of milk the Garcia family have left after lunch.
Step-by-step explanation:
The Garcia family started the day with 2 gallons of milk.
They drank 1 quart of milk for breakfast and 3 pints for lunch.
Since, 1 gallon = 8 pint
2 gallon = 16 pint
and 1 quart = 2 pint
Left amount = 16 pint - ( 2pint + 3pint)
= 16-5
= 11 pints
Hence, 11 pints of milk the Garcia family have left after lunch.

A circle has a radius of 4 x^3 y^5 cm. The area of a circle can be found using A equals pi r^2
What is the area of this circle in square centimeters?
Answer:
Step-by-step explanation:
There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference. The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance. You can also think of the radius as the distance between the center of the circle and its edge.
This diagram shows the circumference, diameter, center, and radius on a circle.
