Answer:
domain: (-infin., infin.)
range: (-infin., infin.)
Step-by-step explanation:
This is an odd degree polynomial which forms a sideways S shape starting low and ending high. Since nothing restricts the function from having an output for every real number input, the domain and range are (-infin., infin.).
Answer:
The linear model of her monthly earnings is; Y =1200 +0.03*X. The amount earned is 1350; choice A
Step-by-step explanation:
Let Y denote her monthly earnings and X her total sales. The linear model can thus be formulated as; Y =1200 +0.03*X. We are then to find the value of Y given X =5000. We simply substitute X =5000 into the linear model which yields; Y =1350
Answer:
y = x - 6
Step-by-step explanation:
The slope of y = -x is -1, so the slope of any line perpendicular to y = -x is +1. Thus,
y = mx + b becomes 2 = 1(8) + b, so that b = -6.
The desired equation is y = x - 6.
Check: Does (8,2) lie on this line? Is 2 = 8 - 6 true? YES.
The answer is B.
(27/123)*360
0.126*360

round to 78
Answer:
Height is 5 ft
Step-by-step explanation:
<em><u>The prism is attached.</u></em>
<em><u></u></em>
The volume formula is:
Where
V is volume
B is area of base
h is height of prism
Now, solving for "h", gives us:
Looking at the prism, it is given:
V = 175
B = 35
Substituting, we get the height:
The height is 5 ft
