You would need exactly 9 correct questions to get a 50%.
We can find this by multiplying the total number of questions by the percentage we are looking for.
18*50% = 9
For this case we have that the point-slope form of a line is given by:
Where:
m: is the slope
are the coordinates of a point through which the line passes.
In this case we have to:
Substituting we have:
Simplifying:
Thus, the point-slope equation form of the line is:

Answer:
Step-by-step explanation:
Let the equation of the exponential function with base 2 is,
Here, a = vertical stretch
c = Horizontal shift
d = Vertical shift
If this function has a vertical stretch by a factor of 3,
Equation will be,
If this function has a shift of 5 to the right,
Equation of the function will be,
If this function has a shift of 6 units upwards,
Answer:
49 cm²
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ← s is the length of the side, thus
s³ = 343 ( take the cube root of both sides )
s = = 7, thus
area of base = s² = 7² = 49 cm²
