The answer to 7 is 4 and the answer to 8 is 2.7
Answer:
a) 395.725
b) 378.75
c) 8.8
Step-by-step explanation:
a) S(8.5) = 11.25(8.5) + 300 = 395.625
b) if she worked 47 hrs, that means there were 7 overtime, h=7 and we have to find S(7).
S(7) = 11.25(7) + 300 = 378.75
c) her salary was 398.61, that means S(h) = 398.61 and we have to find h.
398.61 = 11.25(h) + 300
98.61 = 11.25(h)
h = 98.61 / 11.25
h= 8.8

Answer:
3) y = √10
4) x = 5√2
Step-by-step explanation:
The side ratios of an isosceles right triangle (one of the "special" right triangles) are ...
1 : 1 : √2
So, for some multiplier k, they can be made to match the sides in your triangles.
__
3) 1·k : 1·k : k√2 = √5 : √5 : y
Clearly, k = √5, so ...
y = (√5)(√2)
y = √10
__
4) k : k : k√2 = x : x : 10
k = 10/√2 = (5√2)/2
k = x = (5√2)/2
Answer:
20 units or 4.8

Step-by-step explanation:
The domain is the set of allowed x inputs, or x coordinates of a function. In this case, any point on the curve has an x coordinate that is 4 or smaller.
Therefore, the domain is the set of numbers x such that 
To write this in interval notation, we would write ![(-\infty, 4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%204%5D)
This interval starts at negative infinity and stops at 4. We exclude infinity with the curved parenthesis and include 4 with the square bracket.
-----------------------------------------------------------------------
The range is the set of possible y outputs. Every point on this curve has a y coordinate that is either 0 or it is larger than 0.
The range is the set of y values such that 
In interval notation, it would be written as 
This time we start at 0 (including this endpoint) and "stop" at infinity
note: we always use curved parenthesis at positive or negative infinity because we cannot reach either infinity
