=540 for total angle
540-90(3)-143
=127
pentagon angles all together are always 540 degrees.
Hence,
90+90+90+143+x=540
x= 540-413
x=127

The probability that the photo also has a pet is 0.17
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
We are given that recent survey has shown that 68% of professional photos are of humans, 39% are of pets, and 17% are of both humans and pets.
We need to find the probability that the photo also has a pet.
Therefore,
P(a pet) = 39% = 0.39
P(humans) = 68% = 0.68
P(both humans and pets) = 17% = 0.17
This gives;
P(the photo also has a pet) = 0.17
The probability that the photo also has a pet is 0.17

Find the domain of the relation {(0, 0), (1, 1), (2, 0)). Then determine whether
the relation is a function.
Answers
Answer:
Domain: 0,1,2
The relation is a Function.
Step-by-step explanation:
hope this helps
A relation may or may not be a function.
The domain of the relation is: [0,2]The relation is a functionThe relation is given as:
[tex]\mathbf{(x,y) = \{(0,0),(1,1),(2,0)\}}[/tex]
List out the x-values
[tex]\mathbf{x = \{0,1,2\}}[/tex]
The above set means that the x-values starts from 0 and ends at 2.
Hence, the domain is: [0,2]
For a relation to be a function, all y-values of the relation must point to different x-values.
So, we can say that, the given relation is a function, because all y-values have unique x values

Which equation could generate the curve in the graph below?
On a coordinate plane, a parabola opens down. The parabola is in quadrants 2 and 3, and has its vertex in quadrant 2.
y = –2x2 + 3x – 5
y = –2x2 – 4x – 2
y = –2x2 – 16x– 28
y = –2x2 +16x –28
Answers
Answer:
Its C boys
Step-by-step explanation:
I graphed all of them and compared
The equation that could represent the graph of the parabola is (c) [tex]y = -2x^2 - 16x- 28[/tex]
From the question, we have the following highlights
The parabola opens downThe vertex is in the second quadrantThe second highlight above means that:
The x coordinate (h) of the vertex is negative, while the y-coordinate (k) is positive.
For a parabola: [tex]y = ax^2 + bx + c[/tex], the vertex is:
[tex](h,k) = (-\frac{b}{2a},f(h))[/tex]
Next, we test the options
(a) y = –2x2 + 3x – 5
We have:
[tex]h = -\frac{3}{-2 \times 2}[/tex]
[tex]h = 0.75[/tex]
The value of h is positive.
So, this cannot represent the parabola
(b) y = –2x2 – 4x – 2
We have:
[tex]h = -\frac{-4}{-2\times 2}[/tex]
[tex]h = -1[/tex]
Substitute -1 for x in the function
[tex]k = -2x^2 - 4x - 2[/tex]
[tex]k = -2(-1)^2 - 4(-1) - 2[/tex]
[tex]k = 0[/tex]
The value of k cannot be 0
So, this cannot represent the parabola
(c) y = –2x2 – 16x– 28
We have:
[tex]h = -\frac{-16}{-2\times 2}[/tex]
[tex]h = -4[/tex]
Substitute -4 for x in the function
[tex]k = -2x^2 - 16x- 28[/tex]
[tex]k = -2(-4)^2 - 16(-4)- 28[/tex]
[tex]k=4[/tex]
The x coordinate (h) of the vertex is negative, while the y-coordinate (k) is positive.
Hence, [tex]y = -2x^2 - 16x- 28[/tex] could represent the parabola

Weights: 5, 6, 10, 13 pounds

Determine the unique weights of the juvenile
From the question, we understand that the weights of the juveniles could be any of 5 pounds, 6, 10 or 13 pounds
These values are the unique weights of the juveniles.
In other words, any value other than 5, 6, 10 or 13 can not be regarded as weights of the juveniles.
Hence, the unique weights are 5, 6, 10 and 13

Step-by-step explanation:
We have the function:
[tex]f(x)=a^x[/tex]
Where a>0.
We know that f(4)=256. Therefore:
[tex]\displaystyle f(4)=a^4=256[/tex]
So:
[tex]a^4=256[/tex]
Find the value of a. Take the fourth root of both sides:
[tex]a=\sqrt[4]{256}=4[/tex]
Therefore, our function is:
[tex]f(x)=4^x[/tex]
Hence:

Given that;
There are three graph.
We have to find the solution set of each graph.
What is Number line?
A horizontal line which represent numbers at equal intervals one after another form smaller to greater (From Left to Right), is called Number line.
In the first number line;
At point -2 closed circle is represent that's mean in a set -2 is present and a ray going towards negative direction.
Hence, The solution set of First line is,
⇒ {x | x ≥ -2}
Option 1 is true.
In the second number line graph;
At point -5 the open circle represent that's mean in set - 5 is not present and ray going in the positive direction.
Hence, The solution set of second line is,
⇒ {x | x > -5}
Option 3 is true.
In the third number line graph;
At points -2 and 3 the open circle represent and a line segment is from -2 to 3 is shown.
Hence, The solution set of third graph is,
⇒ {x | - 2 < x < 3}
Option 1 is true.
Therefore,
The solution set of First graph is,

The solution set of second graph is,
⇒ {x | x > -5}
The solution set of third graph is,
