Answer:
7.28
Step-by-step explanation:
1.82*4= 4+3.20+.08= 7.28
Answer:
That would be <u>x = -3</u>
Step-by-step explanation:
As long as the parabola points upwards or downwards, the axis of symmetry would be at the x-value of the vertex.
The epic ms-paint drawing describes some of that.

Answer:
D
Step-by-step explanation:
You are expected to apply your knowledge of the real world to the given situations in order to identify whether the "rate of change" is constant. A constant rate of change means the dependent variable has a linear relationship to the independent variable.
__
<h3>A</h3>
The independent variable is the outside temperature. The dependent variable is the number of people going to the beach. While the number of people going to the beach may increase as the temperature increases, the relationship is unlikely to be linear.
<h3>B</h3>
Points are scored unevenly during a ball game, so cannot be said to have a linear relationship with time played.
<h3>C</h3>
An acrobat flipping on a trampoline has increasing, then decreasing height. Height does not have a constant rate of change with respect to time.
<h3>D</h3>
If bananas are sold by the pound, then the price will be proportional to the weight of the bananas. The rate of change is the constant of proportionality: the price per pound. This situation has a constant rate of change.
This seems to be more of a middle-school-level of a geometry question vs college level.
Either way, what you're doing here is comparing 3 shapes. The square, rectangle, and rhombus. You should definitely know what a square and rectangle look like, but in case you don't know the rhombus, it's the shape that's usually allocated with diamonds, on a 2D plane.
All of these shapes are considered parallelograms. They all have similar features and characteristics, but only to some extent.
Square=Four sides, four 90 degree angles, 2 pairs of opposite congruent angles (meaning all angles are congruent in this case), sum of 360 degrees (90*4)
Rectangle=Four sides, four 90 degree angles, 2 pairs of opposite congruent angles (meaning all angles are congruent in this case), sum of 360 degrees (90*4)
Rhombus= Four sides, Four angles in total measuring up to 360 degrees, 2 acute angles (congruent; less than 90), two obtuse angles (congruent; more than 90). Angle measurements can fluctuate within the 2 acute-2 obtuse parameters. 2 pairs of opposite congruent angles, however, these are not all congruent with each other, unlike the previous two.
All 3 sum to 360 degrees
All 3 have both pairs of opposite angles congruent
All 3 have 4 angles.
