from the given graph: state it's
a) amplitude
b) period
c) function of the graph:
Step-by-step explanation:
The amplitude is 2. Amplitude means height from the x-axis to the crest/trough.
The period is 2pi. It is from crest to crest (next crest) or trough to trough (next trough).
Note that crest are the highest points of a wave, and that troughs are the lowest points of a wave. (we are talking about transverse waves, but this is more of a physics thing).
Function of graph:
By playing around in a graphing calculator, I got the equation to be
2 (cos (x + pi/2)).
the 2 changes the amplitude, and the + pi/2 shifts the graph by pi/2 to the left.

a contracter purchases 7 dozen pair of padded work glovs for $103.32. he incorrectly calculates the unit price at $14.76 what error did th contractor make
Answer:
The contractor made an error in calculating the unit price of the padded work gloves.
Step-by-step explanation:
To find the unit price of an item, we need to divide the total cost of the item by the number of units purchased. In this case, the contractor purchased 7 dozen pair of padded work gloves, which is equal to 7 x 12 = 84 pair of gloves. Therefore, the unit price of the padded work gloves is $103.32 / 84 pair = $1.23 per pair.
The contractor incorrectly calculated the unit price as $14.76, which is an error of $14.76 - $1.23 = $13.53. This error occurred because the contractor did not correctly take into account the number of units purchased when calculating the unit price.
Hope this helps:)

Answer:
x=145° (vertically opposite angles)
Answer:
x= 145 degrees
Step-by-step explanation:
I'm going to assume that the 2 lines are parallel only because if they weren't, the problem would be impossible to solve.
If 2 parallel lines are cut by a transversal, then:
1. Corresponding angles are congruent
2. Alternate interior angles are congruent
3. Alternate exterior angles are congruent
4. Consecutive interior angles are supplementary
So, how do you solve this?
There are many ways.
1. All vertical angles are congruent. In this case, x and a 145 degree angle is congruent. This is one way to show x=145
2. x and another 35 degree angle are consecutive interior angles. They should add up to 180 degrees, 180-35-145. Therefore x=145 degrees.

The length AC in the kite is 8.7 cm.
How to find the side AC in the kite?A kite is a quadrilateral that has two pairs of consecutive equal sides and
perpendicular diagonals. Therefore, let's find the length AC in the kite.
Hence, using Pythagoras's theorem, let's find CE.
Therefore,
7² - 4² = CE²
CE = √49 - 16
CE = √33
CE = √33
Let's find AE as follows:
5²- 4² = AE²
AE = √25 - 16
AE = √9
AE = 3 units
Therefore,
AC = √33 + 3
AC = 5.74456264654 + 3
AC = 8.74456264654

Fred is standing at a point looking north. He walks on a bearing 056° for 9.8km before stopping. He then walks an additional 3.5 km on a bearing of 112° before stopping to rest. (a) Find out how far he is away from his start point using sine or cosine rule (b) Determine the area of the enclosed shape (c) Draw neat labeled scale diagram of the same
The area of the enclosed shape is about 14.47 km^2.
We are given that;
056° for 9.8km and 3.5 km on a bearing of 112°
Now,
We can see that the enclosed shape is a triangle with sides 9.8 km, 3.5 km, and z km, and angles 56°, 112°, and y°. We can use the fact that the sum of angles in a triangle is 180° to find y:
y = 180° - 56° - 112°
y = 12°
Now we can use the cosine rule to find z:
z^2 = 9.8^2 + 3.5^2 - 2(9.8)(3.5)cos(12°)
z^2 ≈ 101.87
z ≈ 10.09
Therefore, Fred is about 10.09 km away from his start point.
To find the area of the enclosed triangle, we can use the sine rule to find x, the height of the triangle:
sin(56°) = x/9.8
x = 9.8 sin(56°)
x ≈ 8.27
The area of a triangle is given by half the base times the height, so:
A = (1/2)(3.5)(8.27)
A ≈ 14.47
Therefore, by trigonometric ratios the answer will be 14.47 km^2.

Is the inverse of the following conditional true?
If t<5, then t>6.
The inverse of the conditional "If t<5, then t>6" is "If t≥5, then t≤6" is not always true but true for some values of t.
What is a function?An expression, rule, or law that defines a relationship between one variable and another variable.
Let's first consider the original statement: "If t<5, then t>6."
This statement is saying that if t is less than 5, then it must be greater than 6, which is impossible since no number can be less than 5 and greater than 6 at the same time.
So the original statement is always false, no matter what value of t we choose.
So, the inverse of "If t<5, then t>6" is "If t≥5, then t≤6".
This statement is saying that if t is greater than or equal to 5, then it must be less than or equal to 6.
This statement is true for any value of t that is greater than or equal to 5 and less than or equal to 6.
Hence, the inverse of the conditional "If t<5, then t>6" is "If t≥5, then t≤6" is not always true but true for some values of t.

Chief purchase 101/2 lbs of beef and 51/2 lbs of of pork she use 132/3lbs of meat how much did she have left
Chief has 2 1/3 lbs of meat left.
Let's start by adding the amount of beef and pork that Chief purchased:
10 1/2 lbs of beef
5 1/2 lbs of pork
The total amount of meat that Chief purchased is therefore:
10 1/2 + 5 1/2 = 16 lbs of meat
Next, we know that Chief used 13 2/3 lbs of the meat. We can subtract this amount from the total amount of meat that Chief purchased to find out how much meat she has left:
16 - 13 2/3 = 2 1/3 lbs of meat
Therefore, Chief has 2 1/3 lbs of meat left.

Which is the closest to the area that is painted blue? A 308 units B. 116 units C. 463 units? D 124 units
Step-by-step explanation:
first of all, all answer options are basically wrong, because an area is always measured in units² (and not just in units).
the blue colored area is the area of the whole square minus the area of the circle.
the side length of the square is 2 times the radius of the circle (the diameter) : 2×12 = 24 units.
so, the area of the square is
24² = 576 units²
the are of the circle is
pi×r² = pi×12² = 144pi units²
so, the blue area is
576 - 144pi = 123.6106579... ≈ 124 units²

amara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible combinations when rolling two number cubes. How many times should Tamara expect the sum of the two cubes be equal to if she rolls the two number cubes 180 times?
Tamara should expect the sum of the two cubes to be equal to 7 around 30 times when rolling the two number cubes 180 times.
To determine how many times Tamara should expect the sum of the two number cubes to be equal to a certain value, we need to analyze the chart and calculate the probabilities.
Let's examine the chart and count the number of times each sum occurs:
Sum: 2, Occurrences: 1
Sum: 3, Occurrences: 2
Sum: 4, Occurrences: 3
Sum: 5, Occurrences: 4
Sum: 6, Occurrences: 5
Sum: 7, Occurrences: 6
Sum: 8, Occurrences: 5
Sum: 9, Occurrences: 4
Sum: 10, Occurrences: 3
Sum: 11, Occurrences: 2
Sum: 12, Occurrences: 1
Now, let's calculate the probabilities of each sum occurring.
Since there are 36 possible combinations when rolling two number cubes, the probability of each sum is the number of occurrences divided by 36:
Probability of sum 2 = 1/36
Probability of sum 3 = 2/36
Probability of sum 4 = 3/36
Probability of sum 5 = 4/36
Probability of sum 6 = 5/36
Probability of sum 7 = 6/36
Probability of sum 8 = 5/36
Probability of sum 9 = 4/36
Probability of sum 10 = 3/36
Probability of sum 11 = 2/36
Probability of sum 12 = 1/36
To find out how many times Tamara should expect a certain sum when rolling the two number cubes 180 times, we can multiply the probability of that sum by 180.
For example, to find the expected number of times the sum is 7:
Expected occurrences of sum 7 = (6/36) \(\times\) 180 = 30
Similarly, we can calculate the expected occurrences for all other sums.
