The time spent to travel a certain distance varies inversely as a car's speed. If it takes 5½ hours to travel a certain distance at 60 miles per hour, how long will it take to travel the same distance at 50 miles per hour?
Select one:
a. 6.6 h
b. 6.9 h
c. 4.6 h
d. 4.2 h
Answer:
6.6h
Step-by-step explanation:
So it takes 5.5 hours going at a speed of 60 miles per hour, multiply these two and we get a distance of 330 milesUse this distance to find the time if speed is 50 miles per hour, so time is derived by dividing the distance by the speed330 miles divide by 50 miles per hour gives 6.6 hourswhat is 7.5% of 61.13
Answer:
Step-by-step explanation:
61.13*7.5%=4.58
61.13+4.58=65.71

A 0.7 kg toy car accelerates at 0.5 m/s2. The FORCE is...
0.35 m/s2
0.35 kg
0.35 N
Answer:
[tex]\boxed {\boxed {\sf 0.35 \ N}}[/tex]
Step-by-step explanation:
Force can be found by multiplying the mass by the acceleration.
[tex]F=m*a[/tex]
The mass of the toy car is 0.7 kilograms and the acceleration is 0.5 m/s²
[tex]m= 0.7 \ kg \\a= 0.5 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F=0.7 \ kg * 0.5 \ m/s^2[/tex]
Multiply.
[tex]F=0.35 \ kg*m/s^2[/tex]
1 kg*m/s² is equal to 1 Newton. The units for force are Newtons.Therefore, our answer of 0.35 kg*m/s² is also equal to 0.35 Newtons[tex]F= 0.35 \ N[/tex]
The force of the toy car is 0.35 Newtons
Answer:
(45 kg)(4.1 m/s)2 = 120 N

Given: If you live in Orlando, then you live in Florida.
Given: Morgan does not live in Orlando.
Conclusion: Morgan does not live in Florida.
Is this sentence Law of Detachment, Law of syllogism, or invalid
Answer:
The law of detachment and syllogism is valid here
Explanation:
The law of detachment and syllogism is associated with inductive reasoning. This law states that a conclusion is valid if the premise or hypothesis is valid, therefore if a then b. In others a results in b.
The law of detachment is denoted
[(a→b)∧a]→b
The law of syllogism derives from the law of detachment. Syllogism says that if a results in b and b results in c, then a results in c. In other words since a causes b and b causes c, then if a then c.
It is denoted
[(a→b)∧(b→c)]→(a→c)
In the above example, given: If you live in Orlando, then you live in Florida
Morgan does not live in Orlando, therefore it is concluded that he does not live in Florida

The function f is continuous on the interval (0,9) and is twice differentiable except at x = 6, where the derivatives do not exist (DNE). Information about the first and second derivatives of f for some values of x in the interval (0,9) is given in the table above. Which of the following statements could be false?
Answer:
The statement that could be false is;
(C) The function has a relative minimum at x = 6
Step-by-step explanation:
The given parameters are;
The function is continuous in the interval 0 ≤ x ≤ 9
The function is not differentiable at x = 6
f prime (x) = Negative for 4 < x < 6, and positive for 6 < x < 8
Therefore, at x = 6, the function is vertical
The statement that could be false is that the function has a relative minimum at x = 6.
A continuous function f(x) does not have discontinuity at any point
The statement that could be false is (c). The function f has a relative minimum at x = 6.
The interval is given as:
Interval = (0,9)
From the question, we understand that the function is not differentiable at x = 6.
This means that the function may or may not have a relative minimum at x = 6.
Hence, the statement that could be false is (c).

To find the y intercept set x=0
You are given two points: (7,-6)(-4,27)
y=mx+b
y2-y1=x2-x1
x1=7
y1=-6
x2=-4
y2=27
27-(-6)/-4-7=27+6/-4-7=33/-11=-3
y=-3x+b
-6=-3(7)+b
-6=-21+b
+21 +21
b=15 so, y=-3x+15
PLUG IN O TO THAT EQUATION
y=-3(0)+15
Your y intercept would be 15
