A tenth is the number that occurs after the decimal
If the number after the tenth is five or higher, then you round up
If the number after the tenth if four or lower, then the tenth stays the same value as it is
In this case, the Ume after the tenth is exactly four, so the value of the tenth stays the same
So your answer is 478.5
Answer:
y= 
x
Step-by-step explanation:
Given the two points:
- Origin (x1, y1) = (0, 0)
- The point (x2, y2) = (5, 9)
Because the x-axis is labeled time (in minutes) and the y-axis is labeled distance (in kilometers).
=>Time, x the independent variable,and distance is the dependent variable.
We have the standard form of a linear equation is:
y= mx + b where a is the slope
We know that, the slope of the function is:
m = 
In this situatuon, m = 
=> y= x + b(1)
The line that goes through (0, 0) so we substitute (0, 0) into (1), we have:
0 = *0 + b
<=> b = 0
So our equation that the graph represents is: y= x
cos (90° - x) should be the answer
The expression that represents the value of sin C - cos C is s-r
From the triangle ABC, since sin B = r and cos B = s.=, hence;
- Opposite side= r
- Adjacent side = s
- Hypotenuse = 1
If m<C is the reference angle, then;
Opposite side= s
Adjacent side = r
Hypotenuse = 1
Sin C = s and cos C = r
Hence the expression that represents the value of sin C - cos C is s-r
