Answer:
D
Step-by-step explanation:
Exponential equation takes the form
where
- a is the initial value ( a ≠ 0), and
- b is the base ( b ≠ 1)
The equation given in the problem can be written as
, so it is <em>an exponential equation, </em> where a = -4.8 and b = 4.
Thus we can say that the initial value = -4.8 and the base is 4
The correct answer is D
Answer:
711
Step-by-step explanation:
They used 79/100 of their money on equipment which means if they have a budget of 900 dollars they used...
900*79/100=9*79=711 dollars on equipment.
Given:
The figure of a triangle.
To find:
The missing length.
Solution:
Let x be the missing length.
Basic proportionality theorem(BPT): According to this theorem, if a line is parallel to the one side of a triangle then that the line intersects the other two sides of the triangle in the same ratio.
Using Basic proportionality theorem, we get




Adding x on both sides, we get




The missing length is 3 Therefore, the correct option is D.
