Answer:
B) All the real numbers except 4.
Step-by-step explanation:
The given rational expression f(x) = 
To find the domain of the rational function, first we have to find the restricted domain.
To find the restricted domain set the denominator equal to zero.
4 - x = 0
x = 4
The restricted domain is at x = 4.
Which means the function does not exist when x = 4. When we plug in x =4 in the rational function, we get the denominator is 0.
Therefore, the function does not exist at x =- 4.
This means except 4 all the real numbers are the domain.
Hope this will help you to understand the concept.
Answer: B) All the real numbers except 4.
Thank you.
Answer:
x<2
Step-by-step explanation:
x+5>2x+3
Step 1: Subtract 2x from both sides.
x+5−2x>2x+3−2x
−x+5>3
Step 2: Subtract 5 from both sides.
−x+5−5>3−5
−x>−2
Step 3: Divide both sides by -1.
−x−1>−2−1
x<2
Answer: 108 cubic inches
Step-by-step explanation:
Hi, to answer this question we have to apple the next formula:
Volume of a rectangular prism (V): base area x height (deep of the soil)
Replacing with the values given:
V = 36 x 3 =108 cubic inches
Ian should put 108 cubic inches of soil in the flower pot.
The volume of the soil is 108 cubic inches.
Feel free to ask for more if needed or if you did not understand something.
Answer:
\int\limits^7_1 {f(x)} \, dx =24
\int\limits^13_7 {f(x)} \, dx =24
Step-by-step explanation:
From Exercise we have f(x)=5-1 , we get f(x)=4.
We calculate integral, if 1≤x<7, we get
\int\limits^7_1 {f(x)} \, dx =\int\limits^7_1 {4} \, dx =4[x]\limits^7_1=4(7-1)=4·6=24
We calculate integral, if 7≤x<13, we get
\int\limits^13_7 {f(x)} \, dx =\int\limits^13_7 {4} \, dx =4[x]\limits^13_7=
=4(13-7)=4·6=24
Therefore, we conclude that the given two integrals are the same.
