2 answers:

8 0

Gradient = 7-(-1)/4-3
= 8
when x = 3, y = -1,
y = 8x + c
-1 = 8(3) + c
c = -1 - 24
= -25
the equation of the line is y = 8x - 25.

Using y=mx+b the answer would be y=8(x-3)-1.

The 5th term in a geometric sequence is 120. The 7th term is 30. What are the possible values of the 6th term of the sequence.

klemol [59]

Answer:

± 60

Step-by-step explanation:

aₙ = a₁ * rⁿ⁻¹

a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶ (1)

a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴ (2)

(1)/(2): 30/120 = 1/4 = r²

r = ± 1/2 or ± 0.5

a₁ = a₇/r⁶ = 30/0.5⁶ = 1920

a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60

1) Jayden runs 1/4 of a mile in 1/4 of an hour. How far will it take him to run 1hr.

Masja [62]

Answer:

Question 1 : If you mean how many miles will he run in 1 hour then it is 1 Mile | Question 2 : 2 Miles

Step-by-step explanation:

Question 1 :

1/4 x 4 (because of the hour being split into fourths) = 1 Mile

Question 2 :

120 / 20 = 6, 6 x 1/3 = 6/3, simplified = 2
