What is the midpoint of the segment shown below?
Answer:
The midpoint is (0,2)
Step-by-step explanation:
To find the x coordinate, average the x coordinates of the endpoints
(-4+4)/2 = 0/2 =0
To find the y coordinate, average the y coordinates of the endpoints
(6+-2)/2 = 4/2 =2
The midpoint is (0,2)
What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
2
O x-3
O x-1
O x + 1
Ox+3
Answer:
Option B
A factor is x-1
Step-by-step explanation:
To find the factors of the polynomial, we will have to look for the roots of the polynomial.
Whenever a polynomial is plotted on a graph, it is important to note that the root of the polynomial refers to the points where the line cuts the x-axis.
From our curve given in the question, the roots of the polynomial are:
x = 1 and x = 6
Let us consider the first root
x = 1
from this, we can get x-1 =0
We will have to take only this as our answer because we are looking for only one of the factors.
Hence, a factor is x-1 and also our correct answer.
Find the value of x.

Answer:
[tex]8^{-5}[/tex]
Step-by-step explanation:
Anything raised to the power of 0 is 1. This means that we need to multiply 8^5 by something to make it into 8^0. When you multiply together two numbers with the same base, you can add the exponents together. For instance, in this case:
[tex]8^{-5}\cdot 8^5= \\\\8^{-5+5}= \\\\8^0=1[/tex]

A student spent 4/7 of an hour each evening reading a book about whales. If it took the student 10 evenings to finish the book, how many hours in all did the student spend reading?
Answer:
40/7
Step-by-step explanation:
If the student read 4/7 of a book 10 times, that means that your equation would be
4/7 • 10 = 40/7
If you want to simplify that even further, you could get about 5.17, but 40/7 is the most simplified, correct answer.
The 3 by 3 grid below shows nine 1 cm × 1 cm 1 cm×1 cm squares and uses 24 cm 24 cm of wire. What length of wire is required for a similar 20 by 20 grid?
Answer:
Length of wire is required = 840 cm
Step-by-step explanation:
Given:
20 by 20 grid
Find:
Length of wire is required.
Computation:
We know that 20-20 grid required 21 lines.
20 cm vertical and horizontal.
⇒ Length of wire is required = (21 + 21)20 cm
⇒ Length of wire is required = (42)20 cm
⇒ Length of wire is required = 840 cm

The mean of the numbers 3, 6, 4, x and 7 is 5. Find the standard deviation.
Answer:
1.2
Step-by-step explanation:
Since (3 + 6 + 4 + x + 7)/5 = 5, then 3 + 6 + 4 + x + 7 equals 25. Adding, we have 20 + x = 25. Thus x = 5. Now we calculate how far each number is from the mean. 3 is 2 away. 6 is 1 away. 4 is also 1 away. 5 is 0 away, and 7 is 2 away. Now, we have to find the mean of this. (2 + 1 + 1 + 0 + 2 ) / 5 is equal to 6/5, which is 1.2
Carmen simplifies the expression (4 y + 8 x + 6) + 25 + (4 x + 6 y + 7). The coefficient of the variable y in her simplified answer is 4. 6. 10. 12.
Answer:
10
Step-by-step explanation:
(4 y + 8 x + 6) + 25 + (4 x + 6 y + 7).
Combine like terms
4y+6y + 8x+4x + 6+25+7
10y+12x+38
Answer:
10
Step-by-step explanation:
original expression:
4y +8x +6) +25+(4x+6y+7)
Let's simplify it step-by-step:
4y+8x+6+25+4x+6y+7x (removing the parentheses)
4y+12x +6+25+6y+7 (adding together similar terms in x)
10y+12x+6+25+7 (adding together similar terms in y)
10y+12x+38 (adding together similar terms with no variable)
So, from the final expression, we see that the coefficient for y is 10.

A man standing in a queue is 37th from the beginning. A girl standing five position in front of him is 24th from the end. How many people are standing in the queue? E.54 F.55 G.53 H.56 PLEASE EXPLAIN
Answer: H 56
Step-by-step explanation:
The girl is standing 5 places in front if the 37th place ie.,32nd place.
There are 31 people standing in front of the girl. She she 24th from the end, there are 23 people behind her.
So total people are 32 + 23 + 1 = 56

Linear increasing
Additional Information:
Linear functions are those whose graph is a straight line.A linear function has the following form:
y=mx+b
m=slope
b=y- intercept
A linear function has one independent variable and dependent variable.The independent variable is X and dependent variable is y.
Initial values are called y-intercept.
A 7-pack of light bulbs costs $2.45. What is the unit price?
per bulb
Answer:
0.35 per light bulb
Step-by-step explanation:
In order to find the unit price per bulb, we must set up a unit rate.
To do this, divide the cost for the pack by the number of light bulbs in the pack.
cost/bulbs
We know that a 7 pack of bulbs costs $2.45.
cost= $2.45
bulbs= 7 bulbs
$2.45/7 bulbs
Divide 2.45 by 7 (2.45/7=0.35)
$0.35 /bulb
The unit price per bulb is 0.35.

Which of the following statements are correct?
Answer:
Triangle DEF is congruent to triangle GHI.
Step-by-step explanation:
There are theorems of congruency. They are SSS, SAS, ASA, and AAS. You can look these up if you are willing to master identifying similarity and congruency in triangles. It is an ideal concept. You can tell based off of marks of eqaulity which triangles are truly congruent. Just remember these theorems dela with angles and sides being eqaul.

Work out Ryan’s average speed for his total return journey detailing how you worked it out.
Answer:
For the return, i guess that you say in the interval between 15:40 and 15:45, that is the moment where he goes back to his home, and pass through the local shop.
Ok, in the graph we can see pairs (time, position)
The average speed can be obtained with two of these pairs, and the average speed is:
As = (position2 - position1)/(time2 - time1)
In this particular case, we have the pairs:
(15:40, 900m) and (15:45, 400m)
(i guess that the distance is in meters)
Then the average speed is:
As = (900m - 400m)/(15:45 - 15:40)
and 15:45 - 15:40 = 0.5 minutes.
As= 500m/5 min = 100 m/min
This means that the average speed in this return is 100 meters per minute
