Answer:
1.6m
Step-by-step explanation:
The length of the blade is 3.2m
The angle which the blade makes is 30°
Assuming the path of the blade and the length it covers is a right-angled triangle,
The length of the blade is the hypothenus while the path at which it clears is the opposite of the triangle.
See attached document for better illustration.
Using SOHCAHTOA,
Sinθ = opposite / hypothenus
opposite = x
hypothenus = 3.2
θ = 30°
Sin30 = x / 3.2
X = 3.2sin30
X = 3.2 × 0.5
X = 1.6m
The path which the snow plough clears is 1.6m
Answer:
Range = {-1, 1, 3}
Step-by-step explanation:
<u><em>The question asks for the range.</em></u>
The function given is
The domain is the set of 3 numbers:
Domain = {4,6,8}
We need to find the range.
First, the range is the set of all y-values for which the function is defined.
When we will be given the domain with a set of numbers, the range would be the numbers that we get when we evaluate the the function at those numbers.
So, we evaluate the function (y-values) at x = 4,6, and 8.
At x = 4:
At x = 6:
At x = 8:
Thus, the range is:
Range = {-1, 1, 3}
Answer:
Car = 10 miles/hour
Bus = 20 miles/hour
Step-by-step explanation:
Here,
Let, the value of the speed of the bus = X
the value of the speed of the car = 2X - 30 (As the speed of the car is 30mph slower than twice)
According to the question,
2X - 20 = 2*(2x-30)
or, 2X - 20 = 4X-60
or, 2X = 40
x = 20
Therefore, the speed of the bus, x = 20 miles/hour
So, the speed of the car is (2*20-30) mph = (40 - 30) mph = 10 miles/hour.
Answer:
0
Step-by-step explanation:
-10 + 10
-10 and 10 are additive inverses, so when we add them, it is equal to zero
-10 + 10 = 0
