What is the average rate of change of the function
f(x) = 2x + 8
over the interval [2, 6)?
The average rate of change of the function f(x) over the interval [tex][2, 6][/tex] is 2.
Important information:
The function is [tex]f(x)=2x+8[/tex].The given interval is [2,6].Average rate of change:The average rate of change of the function f(x) over the given interval [tex][a,b][/tex] is:
[tex]m=\dfrac{f(b)-f(a)}{b-a}[/tex]
Using the above formula, we get
[tex]m=\dfrac{f(6)-f(2)}{6-2}[/tex]
[tex]m=\dfrac{(2(6)+8)-(2(2)+8)}{4}[/tex]
[tex]m=\dfrac{12+8-4-8}{4}[/tex]
[tex]m=\dfrac{8}{4}[/tex]
[tex]m=2[/tex]
Thus, the average rate of change of the function f(x) over the interval [tex][2, 6][/tex] is 2.

Answer:
D. -3z+2
Step-by-step explanation:
Steps:
Remove parentheses: (a) = a
= 5z+9-(8z+7)
....
Simplify
5z+9-8z-7: -3z+2
Answer:
-3z +2
Step-by-step explanation:
A expression in terms of z is given to us and we need to simplify out the given expression . The give an expression to us is ,
[tex]\implies (5z + 9 ) - ( 8z + 7 )[/tex]
Recall that , + × - = - . We have ,
[tex]\implies 5z + 9 - 8z - 7 [/tex]
Combining the like terms and simplifying ,
[tex]\implies 5z - 8z - 7 +9 \\\\\implies \underline{\underline{ -3z +2 }}[/tex]

Which of the following is the value of PQ?
A) 46
B) 61
C) 91
D) 67
Answer:
d.67
Step-by-step explanation:
Answer:
B) 61Step-by-step explanation:
QR = QS
3x + 16 = 7x - 24
16 + 24 = 7x - 3x
40 = 4x
x = 40/4
x = 10
substitute x=10 into PQ = 2x+41
PQ = 2(10) + 41
PQ = 20 + 41
PQ = 61

A hot air balloon in flight begins to ascend at a steady rate. After 1.5 minutes, the balloon is at an altitude of 2150 feet. After 3 minutes, it is at an altitude of 2330 feet. Use an equation in point-slope form to determine the altitude the balloon will reach after 5 minutes.
Answer: hope it helps
Step-by-step explanation:The balloon will not reach 2,500 feet after 4 minutes.
Step-by-step explanation:
The equation of the line in the point-slope form is
A hot air balloon in flight begins to ascend at a steady rate of 120 feet per minute, then the slope is
After minutes, the balloon is at an altitude of feet. This means, the line passes through the point (1.5, 2,150).
Substitute the slope and point coordinates into the equation:
We know that after 3 minutes, the balloon is at an altitude of 2,330 feet. Check this:
Now, find the height after 4 minutes:
Thus, the balloon will reach only 2,450 feet after 4 minutes.

Which statements are always true regarding the
diagram? Select three options.
Omz5 + mz3 = mz4
Omz3 + mz4 + mz5 = 180°
Dmz5 + mz6 =180°
Dm2 + mz3 = mz6
Omz2 + mz3 + mz5 = 180°
Answer:
Step-by-step explanation:
m∠5 +m∠6 = 180° ( the angles form a line)
m∠2 + m∠3 = m∠6 ( exterior angle is the sum of 2 not adjacent angles)
m∠2+m∠3+m∠5= 180° (sum of angles in a triangle is 180°)

Josh was packing to move to another office. He packed 3 2/5 boxes on Tuesday and 2 9/10 boxes on Wednesday. After everything was moved to his new office on Wednesday afternoon, he only found 4 1/4 boxes. How many boxes were missing?
Answer:
2 1/10 boxes were missing.
Step-by-step explanation:
It is given that,
Josh packed [tex]3\dfrac{2}{5}[/tex] boxes on Tuesday
Josh packed [tex]2\dfrac{9}{10}[/tex] boxes on Wednesday
After everything was moved to his new office on Wednesday afternoon, he only found [tex]4\dfrac{1}{4}[/tex] boxes.
We need to find the no of boxes that are missing.
Total no of boxes packed on Tuesday and Wednesday,
[tex]3\dfrac{2}{5}+2\dfrac{9}{10}\\\\=\dfrac{17}{5}+\dfrac{29}{10}\\\\=\dfrac{63}{10}[/tex]
Missing boxes :
[tex]M=\dfrac{17}{4}-\dfrac{63}{10}\\\\=\dfrac{41}{20}\\\\=2\dfrac{1}{20}[/tex]
Hence, 2 1/10 boxes were missing.
