Answer: OPTION C.
Step-by-step explanation:
You can observe in the picture given in the exercise that [tex]\angle E[/tex] is formed by two secants intersecting outside the circle.
It is necessary to remember that, by definition:
[tex]Angle\ formed\ by\ two\ Secants=\frac{1}{2}(Difference\ of\ Intercepted\ Arcs)[/tex]
You can also identify that the Intercepted Arcs are the following:
[tex]CD=110\°\\\\AB=30\°[/tex]
Then, knowing the measures of the Intercepted Arcs, you can substitute them into the equation shown before and then evaluate, in order to calculate the measure of [tex]\angle E[/tex] , which is the angle formed by the intersection of the secants.
Therefore, you get:
[tex]m\angle E=\frac{1}{2}(110\°-30\°)\\\\m\angle E=40\°[/tex]
Could someone please help me with these systems. I have to use substitution.
-7x+2y=18
6x+6y=0
Please show your steps so I can learn too. Thank you.
Final answer:
Using substitution, we solve the equation 6x + 6y = 0 for y, yielding y = -x. Substituting into -7x + 2y = 18 and solving for x gives x = -2. Substituting x back into y = -x, we find y = 2.
Explanation:
To solve the system of equations using substitution, we can isolate one variable in one equation and then substitute it into the other equation. In this case, we've been given the system:
-7x + 2y = 18
6x + 6y = 0
From the second equation, we can isolate y:
6x + 6y = 0
x + y = 0
y = -x
Now, substitute y = -x into the first equation:
-7x + 2(-x) = 18
-7x - 2x = 18
-9x = 18
x = -2
Now that we have the value for x, we can substitute it back into y = -x to find y:
y = -(-2)
y = 2
The solution to the system is x = -2 and y = 2.

The function f is defined by f(x)=2.1x−1.7. Use this formula to find the following values of f. f(x+2)
The value of [tex]f(x+2)=2.1x+2.5[/tex]
Step-by-step explanation:
Given: The function [tex]f(x)=2.1x-1.7[/tex]
Using this formula, we need to find the value of [tex]f(x+2)[/tex]
Hence, we need to substitute [tex]x[/tex] by [tex]x+2[/tex] to find the value of [tex]f(x+2)[/tex]
[tex]f(x+2)=2.1(x+2)-1.7[/tex]
Multiplying the term [tex](x+2)[/tex] by [tex]2.1[/tex], we get,
[tex]f(x+2)=2.1x+4.2-1.7[/tex]
Adding the constant term,
[tex]f(x+2)=2.1x+2.5[/tex]
Thus, the value of [tex]f(x+2)[/tex] is [tex]f(x+2)=2.1x+2.5[/tex]
a pentgon has angle of 104,102,115.111 what the angle of the fifth angle
The fifth angle is 108 degrees
Solution:
Given that a pentagon has angle of 104, 102, 115 and 111 We have to find the angle of fifth angle
A pentagon is a five sided polygon
The sum of all the interior angles of a pentagon is 540 degrees
Given that,
Angle 1 = 104
Angle 2 = 102
Angle 3 = 115
Angle 4 = 111
Angle 5 = ?
Let the angle be "x"
So to find the fifth angle, add all the angles and equate to 540 degrees
Angle 1 + Angle 2 + Angle 3 + Angle 4 + Angle 5 = 540
104 + 102 + 115 + 111 + x = 540
432 + x = 540
x = 540 - 432
x = 108
Thus the fifth angle is 108 degrees
Douglas is making catnip mice to sell in the craft fair eat catnip mouse calls for 5/6 ounces of catnip how many ounces of catnip does he need to make 96 catnip mice
Final answer:
To make 96 catnip mice, Douglas needs approximately 80 ounces of catnip.
Explanation:
To calculate how many ounces of catnip Douglas needs to make 96 catnip mice, we can set up a proportion using the given information. Since each catnip mouse requires 5/6 ounces of catnip, we can set up the proportion: 5/6 ounces / 1 catnip mouse = x ounces / 96 catnip mice. To solve for x, we cross-multiply and divide: (5/6) * 96 = x. Therefore, Douglas needs approximately 80 ounces of catnip to make 96 catnip mice.
Douglas needs 80 ounces of catnip to make 96 catnip mice.
To determine how many ounces of catnip Douglas needs to make 96 catnip mice,
we can use the given information that each catnip mouse requires 5/6 ounces of catnip.
To find the total amount of catnip needed,
we can multiply the amount of catnip required for one mouse (5/6 ounces) by the number of mice (96).
5/6 ounces/mouse * 96 mice =
(5/6) * 96 = 80 ounces
Therefore, Douglas needs 80 ounces of catnip to make 96 catnip mice.

Answer:
15.5 seconds.
Step-by-step explanation:
From the time the driver activated the brakes until he stopped, he travelled 76 - 14 = 62 meters.
During this time the car slowed down from 8 m/s to 0 m/s.
Assuming the deceleration was constant during this time we can apply one of the equations of motion for constant acceleration:
s = (u + v)t / 2 where u = initial velocity, v = final velocity, s = distance and t = the time, so:-
62 = (8 + 0)t/ 2
62 = 8t/2
4t = 62
t = 15.5 seconds.

the width of a box is one third of its length. the height of the box is one third of its width. if the length of the box is 27cm, what is the volume of the box?
a. 81cm³
b. 162cm³
c. 243cm³
d. 729cm³
Answer:
d) 729cm^3
Step-by-step explanation:
Length =27cm
Width = 1/3 of length
= 1/3 of 27cm = 1/3 × 27cm = 9cm
Height = 1/3 of width
= 1/3 of 9cm = 1/3 × 9cm = 3cm
Thus, length = 27cm; width = 9cm; height = 3cm
Hence, volume = length × width × height
= 27cm × 9cm × 3cm
= 729cm^3
Volume is a three-dimensional scalar quantity. The volume of the box is 729 cm³.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of a room or box that is the shape of a rectangular prism is calculated by multiplying the length, width, and height of the prism.
Volume = Length × Width × Height
Given that length of the box is 27 cm. Also, it is mentioned that the width of a box is one third of its length. Therefore, the width of the box is,
Width of the box = (1/3) × 27cm = 9cm
Further, the height of the box is one third of its width. Therefore, the height of the box is,
Height of the box = (1/3) × 9cm = 3 cm
Furthermore, the volume of the box can be written as,
Volume of the box = Length × Width × Height
= 27cm × 9cm × 3cm
= 729 cm³
Hence, the volume of the box is 729 cm³.

Determine if the function f is an exponential function. If so, identify the base. If not, why not? f(x) = x^−3.141
A.) This is not an exponential function because the variable is in the base position.
B.) The base is x.
C.) This is a polynomial.
D.) The base is −3.141.
Answer:
A.
Step-by-step explanation:
The variable x is in the base position so it is not exponential..
An exponential function is where the exponent is the variable , like for example 2^x.
The function f(x) = x^-3.141 is not an exponential function because in an exponential function, the base must be constant, and here x is the exponent, not the base.
Explanation:The function f(x) = x−3.141 is not an exponential function. In an exponential function, the base is a constant and the exponent is the variable. Since the variable x is in the exponent here and the base is not a constant, we do not have an exponential function according to the definition.
Therefore, the correct answer is A: This is not an exponential function because the variable is in the base position and not in the exponent where we typically find the variable in exponential functions.

find the area of the rectangle , i put a pic .
Step-by-step explanation: Notice that the figure shown here is a rectangle so we can find its area by using the formula length x width.
Since the length is 3/7 in and the width is 2/8 in, we can plug this information into the formula to get (3/7)(2/8).
Now multiplying across the numerators and multiplying across the denominators we get 6/56 which can be reduced to 3/28 in².
There are 3x-2 trees planted in each room of a rectangular parecl of land. If there are a total 24x-16 trees planted in the parcel, how many rows of trees are there in the parcel?
Answer:
8 rows of trees are there in the parcel.
Step-by-step explanation:
The number of trees planted in each row = (3 x -2) trees
The total number of trees planted on the land = (24 x - 16)
Let us assume the total number of rows planted = m
Now,as we know:
The plants in each row x The number of rows = Total trees Planted
⇒ (3 x -2) x (m) = (24 x - 16)
[tex]\implies m = \frac{24x-16}{3x-2}[/tex]
Simplifying for the value of m, we get:
[tex]m = \frac{24x - 16}{3x-2} = \frac{8(3x-2)}{3x-2} = 8\\\implies m = 8[/tex]
Hence, the total number of rows planted = 8
Burt’s parents allow him to watch 10 hours of television per week. This week Burt is planning to watch several two-hour movies and four hours of sports. Solve to find the number of movies Burt is planning to watch this week.
After setting aside 4 hours for sports, Burt has 6 hours left for television. Since each movie is 2 hours, Burt can watch 3 two-hour movies in the remaining time.
Burt's parents allow him a total of 10 hours of television per week. Since he is planning to watch four hours of sports, we subtract this amount from the total to find the time remaining for watching movies. Here's how we solve for the number of movies Burt can watch:
Total TV time allowed: 10 hours per week
Time planned for watching sports: 4 hours
Time remaining for movies: 10 hours - 4 hours = 6 hours
Since each movie is two hours long, we then divide the remaining time by the length of one movie:
6 hours divided by 2 hours/movie = 3 movies
Therefore, Burt is planning to watch three two-hour movies this week.

Describe the sequence of transformations that maps triangle XYZ onto triangle X”Y”Z”
Answer:
The transformation
[tex](x,y) \rightarrow (x-5,-y+1)[/tex]
maps triangle XYZ onto triangle X”Y”Z”.
Step-by-step explanation:
Let us take point Z on the XYZ triangle and see what sequence of transformations we have to apply to map it into the point Z''.
Now Z = (-2, 2) and Z'' = (-7, -1).
The x-coordinate goes from -2 ⇒ -7.
The y-coordinate goes from 2 ⇒ -1.
The x-coordinate is just shifted by -5; thus, [tex]x \rightarrow x-5[/tex], and the y-coordinate first transforms as [tex]y \rightarrow -y[/tex], and is then shifted by 1; thus, it transforms as [tex]y \rightarrow -y+1[/tex].
So we have the full transformation
