Answer:
[tex]A=157.07\ cm^2[/tex]
Step-by-step explanation:
Given that,
The radius of a cylinder, r = 5 cm
Height of the cylinder, h = 5 cm
We need to find the lateral surface area of the cylinder. The formula for the lateral surface area of the cylinder is given by :
[tex]A=2\pi r h[/tex]
Put all the values,
[tex]A=2\pi\times 5\times 5\\\\=157.07\ cm^2[/tex]
So, the lateral surface area of the cylinder is [tex]157.07\ cm^2[/tex].

A calculator requires a keystroke assembly and a logic circuit. Assume that 83% of the keystroke assemblies and 88% of the logic circuits are satisfactory. Assuming that defects in keystroke assemblies are independent of defects in logic circuits, find the probability that a finished calculator will be satisfactory. Group of answer choices
Answer:
0.7304
Step-by-step explanation:
According to the Question,
Given That, A calculator requires a keystroke assembly and a logic circuit. Assume that 83% of the keystroke assemblies and 88% of the logic circuits are satisfactory.We have,
P(keystroke satisfactory) =0.83 , P(logic satisfactory)= 0.88
Assuming that defects in keystroke assemblies are independent of defects in logic circuitsSince the events are independent. So, the probability that a finished calculator will be satisfactory
⇒ 0.83×0.88
⇒0.7304

Sam studied guinea pigs for his science fair project. He found that the amount of weight the guinea pigs gained varied directly with the number of calories they consumed.
The guinea pigs gained 1 ounce for every additional 218 calories in their diet. How many additional ounces would they gain if their diet was increased by 1,090 calories? Let W represent the weight in ounces, and let C represent the number of calories.
Answer: C= 1,090 and the W= 5.
If MN=14, NO=11, and QR=27, find the length of PQ. Round your answer to the nearest tenth if necessary. Figures are not necessarily drawn to scale.
Answer:
PQ = 34.4
Step-by-step explanation:
First, we know that the angles in a triangle add up to 180 degrees. Therefore, angle M = 48 and angle R = 74
Next, because there is a corresponding angle in each triangle, they are similar. This means that the ratios between corresponding sides are the same. For example, the side opposite angle O (MN) over the side opposite angle R (PQ) is equal to the side opposite angle N (OM) over the side opposite angle Q (RP)
This can be written as MN/PQ = OM/RP. Note that both the numerators are on the same triangle, and MN and PQ correspond, as well as OM and RP.
We are given MN, NO, and QR. Because NO is opposite a 48 degree angle (angle M) as well as QR (angle P), we can say that NO/QR = another ratio of a pair of corresponding sides. Because we want to find PQ, and both PQ and MN are opposite 74 degree angles, we can say that
NO/QR = MN/PQ
Thus,
11/27 = 14/PQ
multiply both sides by PQ to remove a denominator
PQ * 11/27 = 14
multiply both sides by 27 to remove the other denominator
PQ * 11 = 14 * 27
divide both sides by 11 to isolate the PQ
PQ = 14 * 27 /11
PQ = 34.4
All functions have a domain and a range.
True
False
Answer:
True
Step-by-step explanation:
The definition of the function is a relation with exactly one x for each y. x is the domain, and y is the range, so all functions have a domain and a range.

Step-by-step explanation:
Which graph represents the function?
g(x) = {x if x < 2
{-3 if x >= 2
Step-by-step explanation:We have to graph the function g(x) which is given as:
g(x)= x when x<2
and -3 when x ≥2.
Clearly after looking at the function we see that the function is not continuous since we find the continuity at x=2 as follows.
Left hand limitat 2:
g(2-h)=lim h→0 2-h
=2-0=2
Also right hand limit at x=2 is:
g(2+h)=lim h→0 (2+h)
= 2+0=2
Also g(2)= -3.
As:
Left hand limit= Right hand limit but is not equal to function's value at that point.
Hence, the function is discontinuous at x=2.
so for x<2 we will get a graph of a line y=x.
and for x≥2 we will get a straight line y=-3 parallel to the domain.

What is the end behavior? 10 points!!
Given:
The given function is:
[tex]f_1(x)=-3\cdot 2^{x-5}-4[/tex]
The graph of the function is given.
To find:
The end behavior of the given function.
Solution:
We have,
[tex]f_1(x)=-3\cdot 2^{x-5}-4[/tex]
From the given graph it is clear that the function approaches to -4 at x approaches negative infinite and the function approaches to negative infinite at x approaches infinite.
[tex]f_1(x)\to -4[/tex] as [tex]x\to -\infty[/tex]
[tex]f_1(x)\to -\infty[/tex] as [tex]x\to \infty[/tex]
Therefore, the end behaviors of the given function are:
[tex]f_1(x)\to -4[/tex] as [tex]x\to -\infty[/tex]
[tex]f_1(x)\to -\infty[/tex] as [tex]x\to \infty[/tex]

What is the slope of the line? What is the y-intercept of the line? y = -8x
Answer:
slope= -8/1
y-intercept= 0,0
Answer:
m = -8
c = 0
Step-by-step explanation:
The given equation of the line is ,
[tex]\implies y = -8x[/tex]
We know that the Standard equation of Slope Intercept Form of the line is,
[tex]\implies y = mx + c[/tex]
Where ,
m is slope c is y interceptOn comparing to the Standard form of the line we get ,
[tex]\implies Slope = -8 [/tex]
[tex]\implies y - intercept= 0 [/tex]

f(x) = 1.8x - 10
g(x) = -4
so, for f(x)=g(x) that automatically means
1.8x - 10 = -4
1.8x = 6
x = 6/1.8 = (6/1) / (18/10) = 10×6 / 18×1 = 60/18 = 10/3

Hope it is helpful....There are five students standing in a line with their hats. Suddenly the wind picks up the hats and randomly assigns each hat to a student. What is the probability that no student will get his or her own hat
Answer:
The probability of a person getting their own hat is 1/5 or 20%.
Step-by-step explanation:
If each person has one hat the chances (the probability) of them getting their own hat would be 20%. The chances (the probability) of them getting a hat that belongs to one of the other four students would be 80%. Due to there being 5 hats each person owns 1 hat so there would be a 1 out of 5 chance of them getting their own hat.
