Answer:
The correct answer is B.
Step-by-step explanation:
For B, the x-value is 3 and the x axis is based on hours. The y-value is .75 and the y-axis is based on the snow accumulation in inches.
D is wrong because in incorrectly talks about the unit rate.
A is not correct because it mixes the x and y axis.
C is not correct because it incorrectly induces the unit rate.

Answer:
6.4
Step-by-step explanation:
The given triangle is a Right Angled Triangle with right angle at E.
So, measure of angle E = 90 degrees
measure of angle D = 62 degrees
measure of side FE = 12
We have to find the measure of side DE. Note that side DE is adjacent to Angle D and side FE is opposite to angle D. So we can use tangent ratio to find the measure of DE.
Therefore, the value of DE, rounded to nearest tenth is 6.4
For a quadratic of the form
, we have the quadratic formula
,
where a is the coefficient (number before the variable) of the squared term, b is the coefficient of the linear term, and c is the constant term.
So, given
, we can get that
, and
. We substitute these numbers into the quadratic formula above.
This is our final answer.
If you've never seen the quadratic formula, you can derive it by completing the square for the general form of a quadratic. Note that the
symbol (read: plus or minus) represents the two possible distinct solutions, except for zero under the radical, which gives only one solution.
