MISSING PART OF QUESTION:
Consider the population of four juvenile condors. Their weights in pounds are : 5, 6, 10, 13
Answer:
The unique weights are 5, 6, 10 and 13
Step-by-step explanation:
Given
Weights: 5, 6, 10, 13 pounds
Required
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

Answer: r = 4
Step-by-step explanation:
V = pi * r^2 * h
144 * pi = pi * r^2 * 9
Divide by pi
144 = r^2 * 9
Divide by 9
16 = r^2
Take square root of both sides
rad(16) = rad(r^2)
4 = r
r = 4

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
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

If line QN bisects angle PQR and N is the midpoint of line PR classify each triangle by its angles and sides
Answer:
The answer is "Equiangular, Equilateral"
Step-by-step explanation:
please find the complete question in the file.
In this question, the answer is equiangular, in which the triangle was considered an equilateral triangle with 3 parallel inner angles. It's the measurement of each of these interior angles is 60 degrees, inside an equiangular triangle, and although there 3 parallel sides of an equiangular triangle, so it is just like an equilateral triangle.
Based on the sides and angles of a triangle, triangle PQR would be classified as: an equilateral triangle.
Recall:
An equilateral triangle all three sides that are congruent and also has all of its three interior angles equal to 60 degrees each.In the diagram given (see image attached below), we have the following:
PQ = RQ = 14 (congruent sides)
PN = NR = 7 (N is the midpoint of PR)
Therefore:
PR = PN + NR
SubstitutePR = 7 + 7 = 14
This shows that triangle PQR has equal side lengths measuring 14 units (PQ = RQ = PR = 14).
Also, we are given that:m<QPR = m<QRP = 60 degrees (two congruent angles).
Taking right triangle QNR into consideration,m<NQR = 180 - (90 + 60) (sum of triangle)
m<NQR = 30 degrees
Therefore:
m<PQR = m<NQR + m<PQN
Substitutem<PQR = 30 + 30
m<PQR = 60 degrees.
This means that, triangle PQR has three equal angles measuring 60 degrees each (<PQR = <QPR = <QRP = 60 degrees).
Therefore, based on the sides and angles of a triangle, triangle PQR would be classified as: an equilateral triangle.

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

if f(x) = a^x. and f(4) = 256 find f(5). assume a>0
Answer:
[tex]f(5)=1024[/tex]
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:
[tex]f(5)=4^5=1024[/tex]
