thats the answer
sana makatulong poww huhu
Step-by-Step Solution:
d = 85 ft
r = 85/2 = 42.5 ft
Circumference = 2πr
Therefore,
= 2πr
= 2 * π * r
= 2 * 3.14 * 42.5
= 6.28 * 42.5

So I am looking at the method of elimination but I get a little bit lost why there is a positive +1 underneath the -1 , where does the +1 come from?
Answers
Answer:
it is because its being carried to the other side
Step-by-step explanation:
When you add 1 to negative 1 it becomes 0, so we are trying to make the right hand side equal to the left hand side. If that makes any sense.
When doing this you need to do the inverse operation on BOTH sides of the equation, in this case the equation is
-1 + y = -3
( the inverse operation of subtraction is addition)
So you add 1 to both sides to find out what y equals, -1 + 1 cancels out, -3 + -1 is equal to -2
Therefore the y = -2

Find the value of X. Round to the
nearest tenth.
7.4in
2.4in
x
Answers
Answer:
4.4 inches
Step-by-step explanation:
Here, we are interested in calculating the value of x.
Mathematically, a line that comes from the center of the circle and extends to a chord, divides the chord into two equal parts.
This means what we have is a right angled triangle with the radius being the hypotenuse, the half of the length of the chord as the other side of the triangle.
3.7 is half the length of the chord i.e 7.4/2
Thus;
using Pythagoras’ theorem
x^2 = 2.4^2 + 3.7^2
Pythagoras’ posited that the square of the hypotenuse is equal to the sum of the squares of the other two sides of the triangle.
Thus;
x^2 =5.76 + 13.69
x^2 = 19.45
x = √(19.45)
x = 4.41 inches which is 4.4 inches to the nearest tenth
Answer:
Central angle = 31 / 4 radians
=
Length of the arc = (3 1 / 4) (radius) = 45 in
=
=> radius = 45 in * 4 / (31) = 45 * 4 / (3 * 3.14) in
=
radius = 19.1 in
=

Step-by-step explanation:
Stuck on this question, not very confident with my answers. Photo is attached, please help!
Answers
Part (a)
The notation [tex]A \cap B \cap C[/tex] talks about overlapping or intersecting all three intervals. Your teacher wants to know what numbers are in all three intervals at the same time.
Refer to the diagram below. I've graphed regions A, B and C on the same number line. The vertical separation is to help tell the regions apart. Technically they should all be on the same number line. Notice how the regions overlap on the interval (0, 2] which translates over to [tex]0 < x \le 2[/tex] telling us that the answer must be choice D.
Meaning we exclude 0 but keep 2, and everything in between the endpoints.
Choice C is not possible because x = -1 is not in region C. This means choice A is ruled out also. Choice B is eliminated because x = 3 is not in region A nor region B.
Answer: Choice D=============================================================
Part (b)
As mentioned earlier, the intervals all have in common the region between x = 0 and x = 2. We exclude 0 but keep 2.
Answer: (0, 2]=============================================================
Part (c)
The graph is shown below.
We have an open circle at 0 and a closed circle at 2. There is shading in between those endpoints.
When it comes to graphing the final answer, you'll ignore the separate regions A,B,C and only graph what is shown in purple.
What is the value of this expression when d = 4 7/8 and f = 3 1/2
6 (d - f) + f
Answers
You just have to plug in the numbers into the variables.

f = 3 1/2
The value of the expression 6 (d - f) + f when d = 4 7/8 and f = 3 1/2 is 47/4 or [tex]11\frac{3}{4}[/tex] .
How to Solve Algebra expression?6 (d - f) + f
when d = 4 7/8 and f = 3 1/2
Given the data in the question;
d = 4 7/8 = f = 3 1/2 = What is 6 (d - f) + f = ?First, we convert the mixed fraction into an improper fraction
d = 4 7/8 = ( 8×4 + 7 )/8 = 39/8
f = 3 1/2 = ( 2×3 + 1 )/8 = 7/2
Now, we substitute the values of d and f into the expression.

Use the following information to determine tan(2x).
cos(x)=2/3 and sin(x) is negative
Answers
We have
tan(2x) = sin(2x) / cos(2x)
tan(2x) = (2 sin(x) cos(x)) / (2 cos²(x) - 1)
Recall that
sin²(x) + cos²(x) = 1
and since sin(x) is negative, it follows that
sin(x) = - √(1 - (2/3)²) = -√5/3
Then
tan(2x) = (2 (-√5/3) (2/3)) / (2 (2/3)² - 1) = 4√5

3) Alternate exterior angles = congruent
= -1 + 14x
= 12x + 17
4) Corresponding angles = supplementary (measures add up to 180 degrees)
= 23x - 5
= 21x + 5
\\NONSENSE ANSWERS WILL BE REPORTED\\
Answers
3) x = 9, 125 degree
4) x = 5, 110 degree
Step-by-Step Explanation:
In Q3 :-
Alternate Exterior Angles are Equal.
Therefore,
=> -1 + 14x = 12x + 17
= 14x - 12x = 17 + 1
= 2x = 18
=> x = 18/2 = 9
Therefore, x = 9
Now finding each angle :-
=> -1 + 14x
= -1 + 14(9)
= -1 + 126
= 125
=> 12x + 17
= 12(9) + 17
= 108 + 17
= 125
Hence, both are Equal.
In Q4 :-
Corresponding Angles are Equal.
Therefore,
=> 23x - 5 = 21x + 5
= 23x - 21x = 10
= 2x = 10
=> x = 10/2 = 5
Therefore, x = 5
Now finding each angle :-
=> 23x - 5
= 23(5) - 5
= 115 - 5
= 110
=> 21x + 5
= 21(5) + 5
= 105 + 5
= 110
Hence, both are Equal.
