For which function and interval can the extreme value theorem be applied?
f (x) = StartFraction x Over (x minus 6) squared EndFraction over the interval [3, 5]
f (x) = StartFraction negative 5 Over 2 (x minus 7) cubed EndFraction over the interval (6, 8)
f(x) = 4 tan(πx) over the interval [0, 1]
f(x) = 3ex + 1 over the interval (1, 3)
Answer:
A) f(x)=x/(x-6)^2 over the interval [3, 5]

3. Lizbeth has a lunch box in the shape of a rectangular prism that
measures 11.5 inches in length and 7.2 inches in width. If the lunch box is 4
inches tall, calculate its volume in cubic inches.
Answer:
do 11.5x7.2 that will get you your answer then after that when you get that answer you will divide that by 4
Step-by-step explanation:
Use the equation to
y=2x
7
Answer:
Slope = 2/7
y-intercept = 0
Proportional = yes
It is proportional since we require no additional terms to get y from x and we can multiply each x term by a certain factor to get the y values
Step-by-step explanation:
Generally, we have the equation of a straight line as;
y = mx + b
where m is the slope and b is the y-intercept
From what we can see, the slope of the given line is 2/7
As we can see, there is no y-intercept; so the y-intercept value is 0
As we can see, we can multiply each x value by 2/7 to get the corresponding y-value
What this mean is that both variables are proportional
The sum of three consecutive integers is 9. What is the equation that represents the scenario?

Answer:
8) 10 15/16 ft³
9) 20 5/6 ft³
Step-by-step explanation:
Volume of a rectangular prism is
l * b * h,
Question 8
We're given the area
Area = l * b
So we substitute the area for length and breadth.
Volume = Area * height
Volume = 4 3/8 * 2 1/2
Volume = 35/8 * 5/2
Volume = 175/16
Volume = 10 15/16 ft³
Question 9
Volume = 5 * 1 2/3 * 2 1/2
Volume = 5 * 5/3 * 5/2
Volume = 5 * 25/6
Volume = 125/6
Volume = 20 5/6 ft³
Fill in the blanks. Then, choose the property of addition you used.
_ + 3 = 3 + 7 is it: associated property, commutative property, or identity property?
0 + _ = 5 is it: associated property, commutative property, or identity property?
2 + (6 + 8) =(2 + 6)+ _ is it: associated property, commutative property, or identity property?
can someone please help me?
Answer:
_7 + 3 = 3 + 7 : commutative property,[if something is added or subtracted]
0 +5 _ = 5 is it: identity property.[if 0 is added or subtracted]
2 + (6 + 8) =(2 + 6)+ _8 associated property

Answer:
Problem 1:
Width of the larger version = 2.99 in.
Problem 2:
Friday = 5⅞ miles
Step-by-step explanation:
Problem 1:
Since the cell-phones are similar in shape and the width and length of both are proportional, therefore:
Width of the bigger phone/Width of the smaller phone = length of the bigger phone/length of the smaller phone
Width of smaller phone = 2.6 in.
Length of smaller phone = 5.4 in.
Width of bigger phone = x = ? in.
Length of bigger phone = 6.21 in.
Therefore:
6.21/5.4 = x/2.6
Cross multiply
5.4 × x = 2.6 × 6.21
5.4x = 16.146
Divide both sides by 5.4
x = 16.146/5.4
x = 2.99
Width of the larger version = 2.99 in.
Problem 2:
Jen's goal for the 5 days = 22 miles
The number of miles she ran Mon to Thursday was given.
To meet her goal, let's find the number of miles she has to run to meet her goal.
Thus:
Number of miles to run on Friday = 22 - (4¾ + 5⅛ + 0 + 6¼)
Change to improper fraction
= 22 - (19/4 + 41/8 + 0 + 25/4)
= 22 - ((38 + 41 + 0 + 50)/8)
= 22 - 129/8
= (176 - 129)/8
= 47/8
= 5⅞ miles

The calculator command normalcdf returns the _______ that a randomly selected value falls in a given reigon of a normal probability
Answer:
The percentage of area under a continous probability curve from negative infinity to x.
Step-by-step explanation:
The normalcdf means the normal cumulative density function, it can be accessed from the TI Calculators from the DIST section which also includes the normalcdf, invNorm, tpdf and other distribution functions.
The syntax is as follows :
normalcdf (lower bound, upper bound, mean, standard deviation)
Hence, to Obtian the probability that a value is between a and b, with mean, x and standard deviation, s
The normalcdf is written as normalcdf(a, b, x, s)

1. Bill wants to buy coffee for his class at the LePhooPhoo Coffee Shop. He needs to buy 30 cups of coffee. The large coffees cost $4 and the medium coffees cost $3. If he spends $102 on coffee, how many of each size coffee did he buy?
Answer:
large = 12
medium = 18
Step-by-step explanation:
L + M = 30 => L = 30-M
4L+3M =102
substitute : L with M
=> 4(30-M)+3M =102
120-4M+3M = 102
- M = 102-120
-M = -18
=========> M = 18, L = 12

its equation:
(x – [? ])2+(y - [ ])2= []
Answer:
[tex](x - 5)^2 + (y - (-3))^2 = 16[/tex]
Answer:
(x - 5)² + (y + 3)² = 16
Step-by-step explanation:
(x - h)² + (y - k)² = r²
(h, k) is the center = (5, -3)
r is the radius = 4
r² = 4² = 16

if {a \index{n}} be an Arithmetic sequence , calculate \frac{1}{a1a2} + \frac{1}{a2a3} +...+ \frac{1}{a39a40}
Given:
[tex]a_n[/tex] is an arithmetic sequence.
To find:
The value of [tex]\dfrac{1}{a_1a_2}+\dfrac{1}{a_2a_3}+...+\dfrac{1}{a_{39}a_{40}}[/tex].
Solution:
We have,
[tex]\dfrac{1}{a_1a_2}+\dfrac{1}{a_2a_3}+...+\dfrac{1}{a_{39}a_{40}}[/tex]
It can be written as:
[tex]=\dfrac{d}{d}\left[\dfrac{1}{a_1a_2}+\dfrac{1}{a_2a_3}+...+\dfrac{1}{a_{39}a_{40}}\right][/tex]
[tex]=\dfrac{1}{d}\left[\dfrac{d}{a_1a_2}+\dfrac{d}{a_2a_3}+...+\dfrac{d}{a_{39}a_{40}}\right][/tex]
[tex]=\dfrac{1}{d}\left[\dfrac{a_2-a_1}{a_1a_2}+\dfrac{a_3-a_2}{a_2a_3}+...+\dfrac{a_{40}-a_{39}}{a_{39}a_{40}}\right][/tex]
[tex]=\dfrac{1}{d}\left[\dfrac{1}{a_1}-\dfrac{1}{a_2}+\dfrac{1}{a_2}-\dfrac{1}{a_3}+....+\dfrac{1}{a_{39}}-\dfrac{1}{a_{40}}\right][/tex]
[tex]=\dfrac{1}{d}\left[\dfrac{1}{a_1}-\dfrac{1}{a_{40}}\right][/tex]
[tex]=\dfrac{1}{d}\left[\dfrac{a_{40}-a_1}{a_1a_{40}}\right][/tex]
[tex]=\dfrac{1}{d}\left[\dfrac{a_1+(40-1)d-a_1}{a_1a_{40}}\right][/tex] [tex][\because a_n=a_1+(n-1)d][/tex]
[tex]=\dfrac{1}{d}\left[\dfrac{39d}{a_1a_{40}}\right][/tex]
[tex]=\dfrac{39}{a_1a_{40}}[/tex]
Therefore, the value of given expression is [tex]\dfrac{39}{a_1a_{40}}[/tex].
Between 06 00 and 10 00,the same day ,the volume of water in a reservoir decreased from 24 000L to 18 000L.What was the average rate of decrease in volume of water, giving your answer in L/h?
Answer:
-1.5 L/h
Step-by-step explanation:
The volume of water in a reservoir decreased from 24.000L to 18.000L between 06.00 and 10.00.
We need to find the average rate of decrease in volume of water. It can be solved as follows :
[tex]Rate=\dfrac{18-24}{10-6}\\\\=-1.5\ L/h[/tex]
The negative sign shows the decrease in volume. Hence, the rate of decrease in volume of water is 1.5 L/h.

Answer:
80.5π cm
Step-by-step explanation:
We want to find the area where the label should go onto the can. If we were to take the label and flatten it onto a 2D surface, we would multiply 11.5 cm by the width, which is equivalent to the circumference of the circle. The circumference of the circle can be calculated using the equation 2πr. The radius is 3.5 cm, so the circumference of the circle is 7π. We multiply 7π by 11.5 to get 80.5π cm.
what is the value of x? i need the work for it as well thank you so much!
Answer:
x=19
Step-by-step explanation:
okay so all those angles there are pretty simple. because of the vertical angles theorem, the angles that go across from each other are equal to each other. On a thing like this those intersections are congruent. So knowing this we can assume that (6x+4)=118. so if you solve the basic algebra for that (you can use mathpapa or smt if you really need the work for that) then it comes out as x=19 which you can check.
6x+4=118
subtract 4 from both sides
6x=114
divide by 6 on both sides
x=19
Hope this helps!

In BTR the measure of angle T is three less than four times the measure of angle B. The measure of angle r is third one more than three times the measure of angle B. Find the measure of each angle
Answer:
Step-by-step explanation:
140
Answer:
19° = m∠B
73° = m∠T
88° = m∠R
Step-by-step explanation:
Let x = measure of angle B
then 4x - 3 = measure of angle T
and 31 + 3x = measure of angle R
x + 4x - 3 + 31 + 3x = 180
8x + 28 = 180
8x = 152
x = 19° = m∠B
4(19) - 3 = 73° = m∠T
31 + 3(19) = 88° = m∠R
