Answer:
0.0000016
Step-by-step explanation:
(8×10^-3)×(2×10^-4)
=8×10^-3 × 2×10^-4
= (8×2) × (10^-3 × 10^-4)
=16 × 10^(-3) + (-4)
= 16 × 10^ (-3-4)
=16× 10^(-7)
= 0.0000016
Answer:
(B) The model indicates that teams with coaches who had a salary of 000 million dollars will average a winning percentage 39%, percent.
Step-by-step explanation:
i just did the question
Answer:
Let the speed of the train be x km/h.
Case 1:
Distance = 288 km
Speed = x km/h
Time = Distance/Speed
= 288/x h
Case 2:
Distance = 288 km
Speed = (x+4) km/h
Time = 288/x + 4 h
Since 288/x > 288/x + 4
288/x - 288/x+4 = 1
288[1/x - 1/x+4 ] = 1
[ x + 4 - x / x(x + 4) ] = 1/288
[4 / x^2 + 4x ] = 1/288
x^2 + 4x = 1152
x^2 + 4x - 1152 = 0
x^2 + 36x - 32x - 1152 = 0
x(x + 36) - 32(x + 36) = 0
(x + 36)(x - 32) = 0
x + 36 = 0 , x - 32 = 0
x = -36 , x = 32
x = -36 , rejected since speed cannot be negative.
Therefore , speed of the train = 32 km/h
<h2>
The first term of the given sequence (a) = 6561</h2>
Step-by-step explanation:
Let the first term = a and common difference = d
Given,
= 729 and
= 243
To find, the first term of the given sequence (a) = ?
We know that,
The nth term of a G.P.

The 3rd term of a G.P.

⇒
= 729 ..............(1)
The 4th term of a G.P.

⇒
= 243 ..............(2)
Dividing equation (2) by (1), we get
=
⇒ 
Put
in equation (1), we get
= 729
⇒
= 729
⇒ a = 9 × 729 = 6561
∴ The first term of the given sequence (a) = 6561
Answer: It is linear. When a line is linear it just means it makes a straight line when you graph it. When it isn’t it will be curved or in some weird shape.
