Answer: 5.4
Step-by-step explanation:
Use cosine to find the adjacent side.
cosine = adjacent/hypotenuse
Substitute these values in the cosine equation:
cos(39) = x/7
7*cos(39) = x
Use a calculator to find the value of x:
x = 5.4
Answer: 7.5 minutes (7 min 30 sec)
Step-by-step explanation: If it takes it 3 minutes to travel 2 km, it would take it 1.5 minutes to travel 1 km. So, 1.5 * 5 = 7.5, meaning it would take it 7.5 min to travel 5 km.
by the inverse function definition, we will have that:
<h3>How to find the values of the inverse function?</h3>
Remember that, by definition, for an invertible function f(x) we have that:
f(x) = y
then:
f⁻¹(y) = x
Where f⁻¹(x) is the inverse function of f(x).
Now, we want to find:
f⁻¹(-2) and f⁻¹(1)
If you look at the given table, we can see that we have the points (3, -2) and (0, 1), which means that:
f(3)= -2
f(0) = 1
Then, by the inverse function definition, we will have that:

Answer:
a) 336
b)6
c)6
Step-by-step explanation:
a) In the 1st place fit 8 cars, in the 2nd only fit 7 cars, because one is already in the first place and 3th fit 6 cars, so all the possibilities are 8*7*6.
b) in the 1st place fit 3 cars, 2nd 2 cars and 3th 1 car, so all the possibilities are 3*2*1
c) every shirt can be matched with 1 pair of pants, there are 2 shirts and 3 pants, so all the the possibilities are 6+6.
It would be like this , this is how you would graph it
