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.
A≈1075.21in²
Diameter is 37 inches if that’s useful too.
Answer:
109.5; B
Step-by-step explanation:
From your identity,
CosA = adjacent/ hypothenus
A represent an arbitrary angle between the sides in question.
In the question above, A=64
Hypothenus is the longest side and adjacent is the side just below the angle .
In the above case,
Hypothenus= X
adjacent =48
This means;
Cos64 = 48 /X
X = 48 / cos64; [ from cross multiplication and diving through by cos64]
X = 48 /0.4383 [ cos64 in radian = 0.4383]
= 109.51
= 109.5 to the nearest tenth.
Note( do your calculation of angle in radian or else, you won't get the answer)
Answer:
Those ratios are not equivalent
Step-by-step explanation:
3:4 is not the same as 4:3 because 3:4 means 3 out of 4 but 4:3 means 4 out of 3 which means it is more than one while 3:4 is less than one
A) draw a cube
i) 16cm
ii) 80 cm
b)64 cm
Ok so draw the outline of a cube with 4cm each. There is six sides and the area is just multiplying 4 by 4. So, since the area of each side is 16, and there is 6 sides, the surface area is 80 cm. The volume is just length x width x height (4x4x4) so it’s 64 cm cubed.
