Answer:
2 reflection across the y axis
Part A
The distance that Eric can travel by driving to work can be represented by a linear equation because he sets his cruise control and is moving at a constant rate. He drives at a rate of 75 mph on the interstate for a total of 1.5 hours.
What is the linear equation that can be used to find the distance that Eric travels each day? In the equations d = distance traveled, r = rate and t = time taken.
A. d = rt
B. d = t/r
C. d = r/t
D. d = r + t
E. d = r/75
Part B
What is the total distance that Eric travels each day?
A. 37.5 miles
B. 75 miles
C. 112.5 miles
D. 150 miles
E. 187.5 miles
WILL GIVE BRAINLIEST AND 40 POINTS
Answer:
Step-by-step explanation:
There's a saying to this kind of equation: Rate + Time = Distance and B best fits the saying, so B must be right (Don't quote me on that, it may be wrong)
the linear equation that can be used to find the distance that Eric travels each day is A. d = rt & the total distance that Eric travels each day is C. 112.5 miles.
What is speed?Speed is measured as distance moved over time.
here, given that,
He drives at a rate of 75 mph on the interstate for a total of 1.5 hours.
so, the linear equation that can be used to find the distance that Eric travels each day is A. d = rt
i.e. d= 75*1.5
=112.5
& the total distance that Eric travels each day is C. 112.5 miles.

Answer:
Question 3
Find the range of the function for the domain 2 < x < 3
[tex]f(2)=(2)^2-1=3[/tex]
[tex]f(3)=(3)^2-1=8[/tex]
Therefore, the range of [tex]f(x)=x^2-1[/tex] is [tex]3 < f(x) < 8[/tex] with domain 2 < x < 3
This means that for the function to be continuous, when the domain is x=3, f(x) = 8
[tex]f(3)=2a(3)=6a[/tex]
[tex]\implies 6a=8\implies a=\dfrac43[/tex]
Similarly, when the domain is x > 3, f(x) > 8
[tex]f(3)=b(3)-4=3b-4[/tex]
[tex]\implies 3b-4 > 8 \implies b = 4[/tex]
Therefore, [tex]a=\dfrac43[/tex] and b = 4
Question 5
[tex]\textsf{let}\:u=\ln (x)[/tex]
[tex]\implies \dfrac{du}{dx}=\dfrac{1}{x}\implies dx=x\:du[/tex]
[tex]x=1\implies u=0[/tex]
[tex]x=3 \implies u=\ln 3[/tex]
[tex]\implies \displaystyle \int\limits_{1}^{3} \dfrac{\ln x \sin (\ln x)}{x} \,\:dx=\displaystyle \int\limits_{0}^{\ln 3} \dfrac{u \sin u}{x} \, \cdot x\:du=\displaystyle \int\limits_{0}^{\ln 3} (u \sin u) \, \:du[/tex]
Use integration by parts:
[tex]\displaystyle \int u\dfrac{dv}{dx} \, dx=uv- \displaystyle \int v \dfrac{du}{dx} \, dx[/tex]
[tex]\textsf{where}\:u=u\:\textsf{and}\:\dfrac{dv}{dx}=\sin u[/tex]
[tex]\implies \dfrac{du}{dx}=1\:\textsf{and}\:v=\int \sin u=-\cos u[/tex]
[tex]\implies \displaystyle \int\limits_{0}^{\ln 3} (u \sin u) \, \:du=-u \cos u- \int\limits_{0}^{\ln 3}-\cos u \,\:du[/tex]
[tex]\begin{aligned}\implies \displaystyle \int\limits_{0}^{\ln 3} (u \sin u) \, \:du & =\left[-u \cos u+ \sin u\right]_{0}^{\ln 3}\\ & =[- (\ln 3) \cos (\ln 3)+ \sin (\ln 3)]-[-0 \cos (0)+ \sin (0)]\\\\ & =[- (\ln 3) \cos (\ln 3)+ \sin (\ln 3)]-0\\\\ & = 0.3908925527...\end{aligned}[/tex]

You own a square plot of land and you want to determine its surface area. You know that one side of land measures 10 longer than what the appraisers estimated, but you lost the paperwork with the information. Write an expression to represent the area of your land.
What is the area of the property if x = 12?
The area of the property is the product of its dimensions, and the expression for the area is (x + 10)²
How to determine the expression for area?The area of the land is the product of its dimensions.
Let the length and the width of the land be x.
So, the area measured by the appraisal is:
Area = x²
One side of the land is 10 more than the measured length.
So, we have:
Area = (x + 10)²
Substitute 12 for x
Area = (12 + 10)²
Evaluate
Area = 484
Hence, the area of the property is 484

By rewriting the formula for the multiplication rules you can write a formula for finding conditional probabilities. The conditional probability of event b Occurring giving that event a has occurred is
The probability that an airplane flight departs on time is 0.91
The probability that a flight arrives on time is 0.89.
The probability that a flight departs and arrives on time is 0.84
The probability that a flight departed on time given that it arrives or
(Round to the nearest thousandth as needed
The probability that a flight departed on time given that it arrives is 0.92
Conditional ProbabilityThe conditional probability of event B occurring giving that event A has occurred is expressed as
P(B|A) = P(A and B)/P(A)
Given the following parameters
P(A and B) = The probability that a flight departs and arrives on time = 0.84
P(A) = The probability that an airplane flight departs on time = 0.91
P(B | A) = 0.84/0.91
P(B | A) = 0.92

fifty million of 94 million households watched the last episode of a popular television show. What percentage of households were not watching the show?
The percentage of households that were not watching the show were 46.81%.
Step-by-step explanation:In this case, we need to find the percentage of households that don´t watch the show. First, we need to know how much households don´t watch the show, this is:
[tex]94,000,000-50,000,000=44,000,000[/tex]
So, the households that were not watching the show were 44 million.
Now we can calculate the percentage, to find a percentage we use a division and to introduce the percentage units we multiply by 100.
[tex]\frac{44,000,000}{94,000,000}[/tex] × [tex]100=46.81[/tex]The percentage of households that were not watching the show were 46.81%.

Answer:
70/100 ; 3/10 ; 50/100
Step-by-step explanation:
You need to multiply numbers to make them equivalent.
1st Question:
7/10 has to multiply by 10/10 because the denominator of the other one is 100 and 10 x 10 is 100.
7 x 10 = 70
70/100 shall be your answer.
2nd Question:
This time you need to find your starting point.
A way to do this is to divide/simplify the fraction in order to make it equivalent.
You need to divide by 10 because your quotient and denominator at your starting point is 10 and 100/10 is 10.
30 divided by 10 is 3
Your Answer for this one is: 3/10
3rd Question:
Same thing as the 1st one.
Multiply by 10.
5 x 10 = 50
50/100 is your answer.
If 14 g of a radioactive substance are present initially and 4 yrs later only 7 g remain, how much of the substance will be present after 8 yrs?
5.25 g
Step-by-step explanation:
The half-life of a radioactive substance is the amount of time it takes for half the mass of the substance to decay.
In this question no calculations are required to get half-life. This is because it is given that it took 3 years for the 14g to halve to 7g.
To find amount of the substance after a further 4 years, we’ll use the formula;
Final amount = initial amount / 2ⁿ
Where n = elapse time / half-life
We begin by finding n;
n = 4 years / 3 years
= 4/3
Final amount;
= initial amount / 2ⁿ
= 7 / 2 ^ (4/3)
= 5.25 g
