Answer:
7 is the answer.
Step-by-step explanation:
In equations like this, you would solve the numbers in the parenthesis first, and then gradually do: Multiplication -> Division -> addition -> subtraction.
Therefore, -18 / 9 is -2.
-2 * 2 would be -4,
11 + (-4) would be 7.
Answer : 7.
The circumference= 186000000π miles and the speed or the earth is 7750000π miles per hour.
Step-by-step explanation:
Radius (r) = 93000000 miles
a) circumference= 2πr
= 2π(93000000) miles
= 186000000π miles
b) speed = distance / time
Here distance is the circumference and time is 24hrs because if the earth completes 1 revolution around the sun in 24hrs.
Speed = 186000000π/24
= 7750000π miles per hour
Answer:
72 is the least common multiple
Step-by-step explanation:
The first one is the multiples of 9 and the second one is of 8
The only one they have in common is the number 72
Answer:
True
Step-by-step explanation:
With Sin and Cos, the rule is that the opposites are the same:
SinA=CosB
CosB=SinA
In this problem, it is showing SinA=cosB, so it is the same, it is true.
Hope this helps!
Answer:
Step-by-step explanation:
Rewrite the differential equation as:
Integrate both sides with respect to x:
Integrate one more time both sides with respect to x:
Now that we find the solution, let's find its derivate:
Evaluating the initial conditions:
Replacing the value of the constants that we found in the differential equation solution:
