You can check whether a graph represents a function by using the vertical line test.
Draw a vertical line on the graph, the vertical line intersects the graph at many points, therefore the graph does not represent a function.

Find the angle of one interior angle in this regular polygon, round your answer to the nearest tenth if possible.
Answers
Answer:
144°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 10, thus
sum = 180° × 8 = 1440°
1 interior angle = 1440° ÷ 10 = 144°
The Clark family is taking a trip from Boston to Cleveland to watch Pedro pitch against the Indians. The distance between Boston MA and Cleveland, Ohio is 552 miles. To minimize the sibling rivalries along the way, they are going to extend the trip over two days. The first part of the journey will be exactly 100 miles longer than the second part. How far will the Clark family travel on each day?
Answers
Answer:
They will travel 326 miles on the first day and 226 on the second day
Step-by-step explanation:
We can set up an equation to help us solve it.
Let x be the number of miles they travel on the first part of the journey
We can also write the second part in terms of x. Since it is 100 miles shorter than the first, it can be written as x-100
x+x-100=552
Add 100 to both sides
x+x=652
2x=652
x=326
They will travel 326 miles on the first day and 226 on the second day

Two lines AB and CD intersect at O. If ∠AOC + ∠COB + ∠BOD = 270°Find the measures of ∠AOC, ∠COB, ∠BOD, ∠DOA.
Answers
Answer:
all are 90°
Step-by-step explanation:
Vertical angles are congruent, and linear angles are supplementary, so we have ...
∠AOC + ∠COB + ∠BOD = 270°
180° + ∠BOD = 270°
∠BOD = 90°
Since the lines cross at right angles, all of the angles are 90°.

Answers
Answer:
m= 70
s= 40
a= 110
d= 40
Step-by-step explanation:
Angle M is equal to 70 because it is an isoleases triangle.
The 3 sides of a triangle is equal yo 180. So if angle m is 70, then 70+70 is 140. 180-140 is 40. This makes angle s= 40.
Now we have to find angle a. Angle a and 70 make a straight line. So the line is 180. 180-70 is 110. Angle a is equal to 110.
Now we have to find angle d. As I said before All the angles of a triangle equal to 180. 30+110= 140 now 180 - 140= 40. This makes angle d= 40.
Which of the system(s) below works best to solve by elimination? Why? System 1 : 3m+n=71 2m-n=30
System 2 : 4x+y=1 y=-2x+9
System 3 : 5x+4y=15 5x + 11y=22
Answers
Answer:
first option is easiest since it involves just adding both equations term by term.
3m+n=71
2m-n=30
Step-by-step explanation:
The first system looks like the easiest one, because the two equations are listed already in standard form, and the variable "n" appears as positive "n" in the first equation, and as its opposite "-n" in the second equation. Therefore the elimination method works directly by adding both equations term by term (thus cancelling out completely one of the variables in the resultant/combined equation.
the probability of rolling a 6 on a biased dice is 1/5 1) complete the tree diagram. 2) Work out the probability of rolling two sixes.
Answers
Answer:
Step-by-step explanation:
Not 6 on all rolls in the diagram = 4/5
6 on all rolls in the diagram is 1/5
To find the probablity of rolling two sixes, 1/5 x 1/5 = 4/100 = 0.04 = 4%
1) The completed tree diagram is attached
2) The probability of rolling two sixes as worked out from the tree diagram is; P(6 | 6) = ¹/₂₅
Since the probability of rolling a six on the first roll is 1/5, then probability of not rolling a six on first roll is;
P(not 6) = 1 - 1/5
P(not 6) = 4/5
A) Please find attached the completed tree diagram
B) First Roll;
P(6) = ¹/₅
P(not 6) = ⁴/₅
Second Roll;
Let's begin with the P(6) Section;
P(6 | 6) = ¹/₅ × ¹/₅ = ¹/₂₅
P(6 | not 6) = ¹/₅ × ⁴/₅ = ⁴/₂₅
Let us now solve for the P(not 6) section;
P(not 6 | 6) = ⁴/₅ × ¹/₅ = ⁴/₂₅
P(not 6 | not 6) = ⁴/₅ × ⁴/₅ = ¹⁶/₂₅
Now, since we are looking for the probability of getting two sixes, it is gotten from the above; P(6 | 6) = ¹/₅ × ¹/₅ = ¹/₂₅

Answer:
a(15) = 131
Step-by-step explanation:
Explicit Arithmetic Sequence Formula: an = a1 + d(n - 1)
We are given a1 and d, so plug them in:
an = 5 + 9(n - 1)
To find the 15th term, plug 15 in for n:
a(15) = 5 + 9(15 - 1)
a(15) = 5 + 9(14)
a(15) = 5 + 126
a(15) = 131
Answer:
Step-by-step explanation:
d = 9 ----> d is common difference
[tex]a_{1} = 5\\\\[/tex] ----> first term
In arithmetic sequence, the difference between two terms is constant.
to find nth term,
[tex]a_{n} = a_{1} + (n-1)d\\\\a_{15} = 5 + 14*9\\\\ = 5 + 126\\= 131[/tex]
The ratio of adults to children at a cricket match is 7:3.
There 150 people at the match.
How many children attended the cricket match?
Answers
Step-by-step explanation:
Ratio of adults to children= 7:3
Total no. Of people at the cricket match:150
To find the value of the ratios, 7x+3x=150 ; 10x=150 ; x=150/10:15
So, 7:3 is 7(15) adults to 3(15) children,
Total no. Of adults: 105
Total no. Of children: 45
So, as per the question, the no. Of children that attended the cricket match is 45

Answers
Answer:
B. -5/4
Step-by-step explanation:
We're going to assume that you don't mean
y = 45x -3
which has a perpendicular line with a slope of -1/45.
Rather, we're going to assume that you mean
y = 4/5x -3
so that the slope of the perpendicular line is -5/4.
__
Similarly, we're going to assume that the answer choices are supposed to represent fractions, so that the above slope matches choice B.
_____
If the slope of a line is m, the slope of the perpendicular line is -1/m. The reciprocal of a fraction is the fraction that has numerator and denominator swapped. -1/(4/5) = -5/4.

No = inital amount of C-14 (at time

= amount of C-14 at time t
K = 0.0001
t = time, in years
Answers
Answer:
Step-by-step explanation:
You wrote the formula incorrectly. It is, correctly:
[tex]N=N_0e^{-kt}[/tex]
The k has to be a negative in the formula; if it's not, the time ends up as negative, which will NEVER be the case (unfortunately, time does not go backwards).
If the skeleton contains 67% of the C-14 it contained when the bird was alive, that 67 is our "N". When the bird was alive, it contained 100% of its C-14; so[tex]N_0[/tex] is 100. We know k, e is Euler's number, and we are looking for t.
[tex]67=100e^{-.0001t}[/tex]
Begin by dividing both sides by 100 to get
[tex].67=e^{-.0001t[/tex]
To get that t out from its current exponential position, we take the natural log of both sides. We do this because 1. it's the only way to get an exponent down from that position and 2. because natural logs and e are inverses of each other; natural logs "undo" e's and e's "undo" natural logs.
[tex]ln(.67)=ln(e^{-.0001t})[/tex] Again, because e and ln undo each other:
ln(.67) = -.0001t and solve for t. Take the natural log of .67 on your calculator and get
-.4004775666 = -.0001t and
t = 4004.7 years

The length of the base of a right-angled triangle ABC is 6 centimeters and the length of the hypotenuse is 10 centimeters. Find the area of the triangle.
Answers
Answer:
24
Step-by-step explanation:
Ok, so we see that we have 6 as a leg of the right triangle and 10 as the hypotenuse. As we look closer, we can tell that this makes the Pythagorean triple 6, 8, 10. 6, 8, 10 is just the Pythagorean triple 3, 4, 5 but it is multiplied by 2. So now that we know both the legs of this right triangle, we can use the area of a triangle formula (bh)/2. 6*8=48 and 48/2 = 24 which gives us our answer.

Let A represent the total area of the square and the circle. What is the circumference of the circle when A is a minimum
Answers
Answer:
88.6647727273 cm²
Step-by-step explanation :
The perimeter of the square =(50/2)
= 25 cm
∴ Side of the square = (25/4)
= 6.25 cm
∴ Area of of the square = (6.25)²
= 39.0625 cm²
The circumference of the circle =(50/2)
= 25 cm
∴ 2πr = 25
⇒ r = 25/(22/7)(2)
Area of the circle = (22/7) { 25/(22/7)2} {25/(22/7)2}
= (25×25×7) / (2×2×22)
= 4365/88
= 49.6022727273 cm²
∴ Total area of the circle and the square =(49.6022727273+39.0625000000)
= 88.6647727273 cm²

The hypotenuse of a right triangle is 9[tex]\sqrt{2}[/tex] cm, and the shorter leg is 9 cm. Find the length of the other leg.
Answers
Answer:
9 cm
Step-by-step explanation:
If you were to imagine this right triangle, you would find it to be a 45 - 45 - 90 triangle. Perhaps the " shorter leg " piece of information was present to trick you, considering that the legs are congruent by converse to base angle theorem.
How is this triangle a 45 - 45 - 90? In such a triangle, the legs can be posed as x cm, as the base angles are congruent ( 45 and 45 ), thus the legs of the triangle are congruent as well. The hypotenuse would be x√2, and as we can see -
If legs = x, Hypotenuse = x√2 = 9√2
Thus, the length of the other leg is 9 centimeters ( 9 cm )
