Answer:
t=-10 or t=20
Step-by-step explanation:
We want to solve the equation:
We use the definition of the absolute value function to get:
Divide through the first equation by -1 to get:
We now add 15 to both sides of the equation to get:
Divide through by 3
Answer:
see explanation
Step-by-step explanation:
To find k, calculate the ratio of corresponding sides, image to original, that is
k = =
=
Thus
QR' = × QR =
× 21 = 2 × 3 = 6 , that is
x = 6 → C
If the sequence is -4,-8,-16,.. then the seventh term be -256.
Given a sequence be -4,-8,-16,...
We are required to find the seventh term of the sequence.
If we carefully observe the sequence then we will find that the sequence is a geometric progression.
Geometric progression is a sequence which has a common ratio between all the terms.
Ratio of 2nd and 3rd term=-8/-4=2
Ratio of 3rd and 2nd term=-16/-8=2
Because the ratio is equal, so the sequence will be called a geometric progression.
Nth term of G.P=a
7th term=-4*
=-4*64
=-256
Hence if the sequence is -4,-8,-16,.. then the seventh term be -256.
