Answer: -8
Step-by-step explanation:
We must remember that, in geometric sequences, the ratio between the consecutive terms is constant.This is called "Common ratio" and is represented with "r".
We need to find the common ratio of this geometric sequence:
Divide one term by the previous term:
Then, the next term asked in the exercise can be found by multiplying -4 by 2.
Therefore, this is:
Answer:
-8
Step-by-step explanation:
r=2
so multiply third term by 2
Answer:
y=mx+c
We have to find the value of m and c.
Let's substitute the value of x and y from the table.
When x=1, y=15,
15= m(1)+c
m +c= 15 ------(1)
Now substitute another set of x and y values.
When x=2, y=24,
24= m(2)+c
2m +c= 24
c= 24 -2m ------(2)
Let me rewrite the two equations so that it is clearer for you to see.
m + c= 15 -----(1)
c = 24 -2m -----(2)
subst. (2) into (1):
m+ 24-2m= 15
-m= 15-24 (bring constants to 1 side, m terms to the other)
-m= -9 (simplify)
m= 9 ( divide by -1 throughout)
subst. m=9 into (2):
c= 24 -2(9)
c= 24-18
c= 6
Thus, the equation is y=9x+6.
When the cat is 3 years old, x=3.
When x=3,
y= 9(3)+6
y= 33.
Hence, the cat is 33 years old in human years.
36 is 90 percent of 40.
We have,
To determine what percentage 36 represents in relation to the whole value of 40.
To do this, we use the formula for finding a percentage:
Percentage = (Part / Whole) x 100
In this case, the part is 36, and the whole is 40.
By substituting these values into the formula, we get:
Percentage = (36 / 40) x 100
Simplifying the calculation:
Percentage = 0.9 x 100
Percentage = 90
This means that 36 is equal to 90% of 40.
In other words, 36 represents 90% of the totalvalue of 40.
Thus,
36 is 90% of 40.
