Answer:
umm i can try to help you with the test
Step-by-step explanation:
Answer:
it seems like the first term is -64, so lets write the formula accordingly:
a_n = a1(r)^(n-1)
where 'n' is the number of terms
a1 is the first term of the sequence
'r' is the ratio
the ratio is 
because -64 * = 16 and so on...
the explicit formula is :
= 
Volume = l*b*h
1. Ans 24 unit cubes
Because it had 6 unit cubes as length, 2 unit cunes as breadth and 2 unit cubes as height.
2. Volume = l*b*h
= 30*15*4
=1800 cubic feet
Answer: f(x) = –3x + 14
Step-by-step explanation:
The point slope form of an equation is expressed as
y - y1 = m(x - x1)
The given equation is
y + 1 = –3(x – 5)
Comparing with the point slope equation,
y1 = - 1
Slope, m = - 3
x1 = 5
The equation of a straight line can also take the slope intercept form,
y = mx + c
Where
m is the slope(change in y /change in x)
c represents the intercept.
We would determine the intercept by substituting x = 5 , y = -1 , m = - 3, into y = mx + c. It becomes
- 1 = - 3 × 5 + c
- 1 = -15 + c
c = - 1 + 15 = 14
The equation becomes
y = -3x + 14
Answer:
13+8(n-1) is the pattern of how this series goes on where n is the number of entities being added.
Write n at the top of sigma notation which is 5 here. And write the pattern infront of sigma notation which is 13+8(n-1)here.
