Well P(x) is the total money they made.
so if P(X) < 0 they had a loss.
so if you plug in 0 you get
0=-7520x^2+15000x
add 7520x^2 to both sides
7520x^2=15000x
(7520x)x is the same thing, if you multiply it out it will still equal 7520x^2
so (7520x)x=15,000x
divide both sides by x and
7520x=15,000
divide both sides by 7520
x=1.995
then you would just need to check a number on both sides,
i.e. 0 and 2
2 gives you a value of -80 which means anything greater then 1.995 would be negative
Answer:
10
Step-by-step explanation:
So 1:3:5 will be a total of 9 (1 + 3 + 5), so 90 divided into the ratio of 1:3:5 will be 10.
I hope this helps, have a nice day! :D
Answer:
Radius = 8.575 cm
Step-by-step explanation:
Formula for volume of a pyramid is;
V_p = ½Ah
Where A is area of base and h is height
Also, formula for volume of cone is given as;
V_c = ⅓πr²h
Now, we are told that V_p = V_c and that h is the same for both shapes.
Thus ;
½Ah = ⅓πr²h
h will cancel out to give;
½A = ⅓πr²
Cross multiply to give;
3A/2π = r²
Base area of pyramid is given as 154 cm². Thus;
(3 × 154)/2π = r²
r = √((3 × 154)/2π
r = 8.575 cm
Answer:
16(x + 3)
4(7x + 8y)
w(11 + h)
Step-by-step explanation:
16x + 48
The greatest common factor of 16 and 48 = 16
Hence, expressing 16x + 48 in factored form:
16x + 48 = 16(x + 3)
28x + 32y
Greatest common factor of 28 and 32 = 4
Hence,
28x + 32y = 4(7x + 8y)
11w + hw
11w + hw = w(11 + h)
D. is the correct answer, as functions cannot have the same x value correspond to different y values. For a function to be considered a function, it must always pass the vertical line test.
