Answer:
B) 
Step-by-step explanation:
We are given,
The graph of the parabola opens downwards.
This means that the leading co-efficient of the function will be negative.
So, options C and D are not possible.
Moreover, it is given that the graph cuts x-axis near
i.e.
= 1.5 and
i.e.
= 4.5.
i.e. At y=0, the value of x is near
and
.
A. So, in
, we put y =0.
i.e. 
i.e. 
i.e. x = 0.68 and x = 3.41
We see that this does not crosses the x-axis at the given points.
So, option A is wrong.
B. Also, in
, we put y =0.
i.e. 
i.e. 
i.e. x = 1.68 and x = 4.41.
Thus, this equation cuts the x-axis near the given points i.e. 1.5 and 4.5.
Hence, the equation of the given graph is
.
Answer:
The sequence of transformation used to map ABC onto A"B"C" is reflection, then rotation, then translation.
Step-by-step explanation:
To map ABC onto A"B"C" steps are:
step 1: Reflection of ABC
step 2: rotation of A'BC by some angle to obtain A'B'C'.
step 3: translation of A'B'C' by some units to the right to obtain the given transformation A"B"C".
Answer:
69
Step-by-step explanation:
to find f(3), we'll have to substitute x with 3
therefore,
f(3) = 19 × 3 + 12
= 57 + 12
= 69
If the hundreth digit is equal to or larger than 5, increase the tenths digit by 1 and get rid of the hundreths digit altogether.
Answer:
there are 16 1/4s
Step-by-step explanation:
1 = 1/4 x 4
2 1/2 + 4 = 6 1/2
4 = 1/4 x 16
