I believe if b were to equal the value of 0, there would be 2 solutions to the function. Or not mainly if the resulting expression turns out to be a difference of squares.
Eg. f(x) = 2x^2 + 0x + 2
2x^2 + 2
2(x^2 + 1)
Here there would not be x intercepts, mainly because x cannot be solved.
Answer:
49x + 114
Step-by-step explanation:
[ [ fireplace ] x = area of 5
] x + 6
5x
patio = area of 5 + 49x + 114
5x + 19
(5x + 19) ( x + 6) = 5 + 19x + 30x + 114
(5 + 49x + 114) - (5 ) = 49x + 114
(area of patio and fireplace) - (area of fireplace) = (area of patio only)
Answer:
1,116 USD
Step-by-step explanation:
1=1.55 that is a 55% increase. 55% of 720 is 396. 720+396=1,116 USD
Using the percentile concept, it is found that 10 students scored lower than he did.
<h3>What is the meaning of the percentile of a measure?</h3>
When a measure is in the xth percentile of a data-set, it is greater than x% of the measures and lesser than (100 - x)%.
In this problem, he scored on the 20th percentile, that is, higher than 20% of the 50 students. Then:
0.2 x 50 = 10.
10 students scored lower than he did.
