Answer:
The common ratio is -2.5
The next three terms are;
-125, 312.5 and -781.25
Step-by-step explanation:
Here, firstly we want to determine the common ratio
To
do this, we have to divide the succeeding term by the preceding term
We have this as;
50/-20 = -20/8 = -2.5
Now, to get the next terms,
we multiply the given last term by the common ratio
That will be;
50 * -2.5 = -125
next is to multiply this by the common ratio
That will be;
-125 * -2.5 = 312.5
And lastly, we have
312.5 * -2.5 = -781.25
Y = mx + b
slope(m) = 3/4
(3,7)...x = 3 and y = 7
now we sub...we r looking for b, the y int
7 = 3/4(3) + b
7 = 9/4 + b
7 - 9/4 = b
28/4 - 9/4 = b
19/4 = b
equation is : y = 3/4x + 19/4...lets put this in standard form
y = 3/4x + 19/4
-3/4x + y = 19/4...multiply by -4
3x - 4y = -19 <== standard form
if (x,5) is on the line
3x - 4y = -19.....sub in 5 for y
3x - 4(5) = -19
3x - 20 = -19
3x = -19 + 20
3x = 1
x = 1/3 <====so point a = (1/3,5)
To find the length of one side calculate the square root of 20
Answer:
Step-by-step explanation:
2.788 x 10^7
so 2.788 x 10 to the power of 7 = 1 mile
