Answer:
Change in sulfur oxide in the air =
Step-by-step explanation:
Data provided in the question:
Relation between the amount of sulfur oxide in the air and the population as:
S² = 110P² + 20P + 600
Population growth rate, = 10 people per month
Now,
change in sulfur oxide with time i.e
differentiating the given relation with respect to time 't'
we have
= + 20
at P = 100 and = 10 people per month
we have
= 2 × 110 × 100 × 10 + 20
or
= 220020
or
=
or
Change in sulfur oxide in the air =
First use the compass to make a circle on the line then move the compass and do it again so that the circles cross. use the straight edge to make a line through where the circles intersect and you're finished.
Answer:
no n 16
Step-by-step explanation:
cost for 3 pencils, a hat, and 2 binders
= 3*0.3+14.5+2*3.2
= $21.8 > $20
so estimate not good
5/0.3=16.6....
so she can buy 16 pencils
A
three times x = 3 × x = 3x
less 5 means subtract 5 from 3x, hence
3x - 5 → A
Answer:
Cartesian plane: This is a particular case of a coordinate plane, such that we have two (or more) perpendicular axes, and usually is used for rectangular coordinates.
Two-dimensional: A coordinate plane can be two-dimensional, some examples are polar coordinates, where the coordinates are the radius and the angle, or rectangular coordinates, where the variables are x and y.
Three-dimensional: Similar to before, a coordinate plane can be three-dimensional in several ways, like in spherical coordinates or cylindrical coordinates.
Extends forever: The axes in a rectangular coordinate plane extend forever, so this description also works.
Perpendicular axes: In some cases, like in rectangular coordinates, the axes are perpendicular, (but not always) so this can also be used.
Parallel axes: As each axis is measured along its length, having two parallel axes will be useless (as we could use only one axis instead of two) so this is the only one that would not apply to a coordinate axis.
