Sorry if this is wrong and it doesn't hep but I got 32
Step-by-step explanation:
Objective: Solving Piecewise Functions
Analyze the info in the graph.
We know that if x=1, the graph will coincide at 5.
If x is greater than 1, the answer will be x squared it answer so any positve interger greater than 1 the answer is that squared.
If x is less than 1, the answer will be double that x.
Let check the answer choices.
A is wrong because x is less than 1 so the answer should be 2(-2)=-4 not 4.
C is Wrong, since 5 is greater than 1, it must be 25 so 5^2=25
D and B are both right, 2 is greater than 1 so 2 squared =4 and Whenever x=1, it will equal 5.
Answer:
Algebraic properties can be used as "reasons" in a two-column proof.
Step-by-step explanation:
- Algebraic properties can be used as "reasons" in a two-column proof.
Let's take an example:
Given: F = 9/5C + 32
Prove: C = 5/9(F-32)
Statements Reasons
1) F = 9/5C + 32 1) Given
2) F-32 = 9/5C 2) subtraction
3) 5/9(F-32) = C 3) multiplication
4) C = 5/9(F-32) 4) symmetric property
Therefore, we conclude that Algebraic properties can be used as "reasons" in a two-column proof.
Answer:
22,500 feet
Step-by-step explanation:
Initial Height of the airplane = 35000 feet
Rate of descend = 2500 ft/min
This means for every minute the height of the plane is decreasing by 2500 feet.
We have to find how high above the sea level is the airplane after 5 minutes.
Since, in one minute the distance of plane is decreasing by 2500 feet, in 5 minutes the decrease in its distance would be = 2500 x 5 = 12,500 feet
Thus, after 5 minutes the height of airplane would have decreased by 12,500 feet. Since, the initial height of airplane was 35,000 feet, the new height after 5 minutes would be:
Height after 5 minutes = 35000 - 125000 = 22,500 feet
After 5 minutes, airplane is 22,500 feet above the sea level
