Answer:
76454
Step-by-step explanation:
Sequence : 14,56,224, ..14(4^(n-1)
where n=term number.
First term: 14*(4^(1-1)) = 14*(4^0) = 14
Second term: 14*(4^(2-1))=14*4 = 56
Third term: 14*(4^(3-1))=14*16 = 224
...
7th term: 14*(4^(7-1)) = 14*(4^6)
Sum of the first 7 terms
= 14*(4^0+4^1+4^2+4^3+4^4+4^5+4^6)
= 14(4^7-1)/(4-1)
= 14(4^7-1)/3
= 76454
2 16/100 this would be that as a fraction. I'm a little confused as to what your asking
your answer is
b = 15 pi
length of ypx = circumfrance of circle - 1/4 of circumfrance of circle
= 2pi r - 2pi r/4 = 6 pi r / 4 = 3 pi r / 2
= 3 pi × 10/2 = 15 pi
The equation of a parabola that opens up and has the following x intercepts (-3,0) and (4,0) is
<h3><u>Solution:</u></h3>
We have to find the equation of a parabola that opens up and has the following x intercepts (-3, 0) and (4, 0)
x-intercepts of the parabola are (−3, 0) and (4, 0)
So, we can form an equation:
Also x = 4
x – 4 = 0
x – 4 = 0 is another factor of quadratic equation.
The quadratic function is:
Hence, the equation of the parabola is
