Answer:
-2
Step-by-step explanation:
Using the squeeze or sandwich Theorem,
A limit of f(x) exists if
Two functions g(x) and h(x) lie above and below respectively for values near the limit.If they all approach the same limit.Since the statement establishes, that let see if they approach the same limit.
[tex]g(2) = {2}^{2} - 3(2) = - 2[/tex]
[tex]h(2) = 2 - 2(2) = - 2[/tex]
So the answer is-2

A point has the coordinates (m, 0) and m ≠ 0.
Which reflection of the point will produce an image located at (0, –m)?
a reflection of the point across the x-axis
a reflection of the point across the y-axis
a reflection of the point across the line y = x
a reflection of the point across the line y = –x
Answers
Therefore the reflection of the point (m,0)and m≠0 will produce an image located at (0,-m) when reflection occurs across the line y=(-x).
Answer:
a reflection of the point across the line y = –x
Step-by-step explanation:
Let m = 5.
Graph (5, 0).
Then graph (0, -5).
Then draw the line y = -x.
You will see that the line y = -x is the axis of symmetry for the two points.
Answer:
a reflection of the point across the line y = –x

the problem below is asking how to find the surface area of the cylinder. please leave an explanation on how to solve it.
formula: 2(3.14)(r)^2 + 2(3.14)(r)
r: radius
Answers
Answer:
3315.84mm^2.
Step-by-step explanation:
We calculate the diameter of the base of the cylinder using Pythagoras:
40^2 = d^2 + 32^2
d^2 = 40^2 - 32^2 = 576
d = sqrt 576 = 24 mm.
So the radius = 1/2 diameter = 12 mm.
The surface area
= 2(3.14)(12)^2 + 2(3.14)(12)(32)
= 904.32 + 2411.52
= 3315.84.
Megan has a case shaped like a right prism. She knows that the area of the base of the case is 16 in and the volume of the case is
352 in
What is the height of Megan's case?
O 17 in
22 in
27 in
32 in
Answers
Answer:
22 in
Step-by-step explanation:
volume of a right prism = area of base x height
Given:
volume = 352 in³area of base = 16 in²⇒ 352 = 16 × height
⇒ height = 352 ÷ 16
⇒ height = 22 in
Height be x
Volume=Area of base×height[tex]\\ \rm\rightarrowtail 16x=352[/tex]

Answer:
1 7/20
Step-by-step explanation:
So, you added the 15/20 and 12/20 to get 27/20
Then to simplify 27/20 you have to see how many times 27 can go into 20
27 can go into 20 with a remainder of 7 which then will lead you to the answer of 1 7/20 and you can't simplify it anymore.

A country’s population in 1991 Was 211 million in 1998 it was 215 million estimate the population in 2012 using the exponential growth formula
Answers
Answer:
The population in 2012 is estimated in approximately 223 million people
Step-by-step explanation:
Exponential Growth
The formula for exponential growth of a variable P at the growth rate r, as time t goes on in discrete intervals, or at integer times 0, 1, 2, 3, ..., is :
[tex]\displaystyle P(t)=P_0(1+r)^{t}[/tex]
Where Po is the value of P at time 0.
The country’s population in 1991 was 211 million, and in 1998 it was 215 million. We have two discrete times to define the equation and set the year 1991 as t=0. Thus, the year 1998 is t=7.
The preliminary equation is:
[tex]\displaystyle P(t)=211(1+r)^{t}[/tex]
To find the value of 1+r, we use the second point (7,215):
[tex]\displaystyle 215=211(1+r)^{7}[/tex]
Dividing by 211:
[tex]\displaystyle \frac{215}{211}=(1+r)^{7}[/tex]
Solving:
[tex]\displaystyle (1+r)=\sqrt[7]{\frac{215}{211}}[/tex]
Calculating:
[tex](1+r)=1.002686[/tex]
The complete equation is:
[tex]\displaystyle P(t)=211(1.002686)^{t}[/tex]
Estimate the population in 2012 (t=21):
[tex]\displaystyle P(21)=211(1.002686)^{21}[/tex]
[tex]P(21)\approx 223[/tex]
The population in 2012 is estimated in approximately 223 million people

Step-by-step explanation:
A statistics teacher gives a multiple-choice exam with 20 questions. The teacher wants to discourage guessing on the exam, so for each question the student earns 1 point for a correct answer, 0 points for no answer, and -1 point for a wrong answer. Consequently, if a student answered every question incorrectly the student would earn a score of -20 on the exam. However, if a student answered every question correctly, the student would earn a score of 20 on the exam. After the exam, the teacher distributes the list of test scores and asks the class to calculate the standard deviation. The first student to finish the calculations says that the standard deviation is -1.8.
a. True
b. False
Answers
Answer:
b. False
Step-by-step explanation:
The answer is false because the standard deviation was miscalculated.
We can compute the formula for calculating the standard deviation as:
[tex]\sigma = \sqrt{\dfrac{\sum (x_i-\overline x)^2}{n}}[/tex]
As a result of the square in the numerator of the summation, the square [tex]\sum (x_i-\overline x)^2[/tex] is usually non-negative.
Even if the data is positive, negative or zero, as a result of the above claim, the standard deviation is always non-negative.
Thus, the fact that the first student who finishes the calculation first and claim that the standard deviation is -1.8 is false.

THIS IS URGENT. PLEASE HELP. given AC=30, find the value if x, and the length of BC
Answers
Answer:
The value of x is 4.8. The length of BC is 14.6.
Step-by-step explanation:
I combined the two expressions 3x+1 and 2x+5 to 5x+6=30
1. I subtracted 6 from 6 and 30 in the equations.
2. I was left with 5x=24
3. I then divide 5 from 5x and 24
4. I got x=4.8
To get the length of BC
2x+5
1. I multiplied 2×4.8
2. I got 9.6
3. I then add 5 to 9.6
4. I finally get the answer 14.6 which is the length of BC
Answer:
[tex]\overline{BC}=14.6[/tex]
Step-by-step explanation:
we know that
[tex]\overline{AC}=\overline{AB}+\overline{BC}[/tex]
so
[tex]30=3x+1+2x+5\\\\30=(3x+2x)+(1+5)\\\\30=(3+2)x+(1+5)\\\\30=5x+(1+5)\\\\30=5x+6\\\\5x+6=30\\\\5x+6-6=30-6\\\\5x+0=30-6\\\\5x=30-6\\\\5x=24\\\\\frac{1}{5}(5x)=\frac{1}{5}(24)\\\\\frac{5}{5}x=\frac{1}{5}(24)\\\\\frac{1}{1}x=\frac{1}{5}(24)\\\\x=\frac{1}{5}(24)\\\\x=\frac{24}{5}\\\\x=4.8[/tex]
and now we solve for BC
[tex]\overline{BC}=2x+5\\\\\longrightarrow x=4.8\longleftarrow \\\\\overline{BC}=2(4.8)+5\\\\\overline{BC}=9.6+5\\\\\overline{BC}=14.6[/tex]
so that's our answer
