Answer:
a) 0.071
b) 0.884
Step-by-step explanation:
a)
7.1 * 10^(2) = 7.1 * 0.01 = 0.071
b)
(6.8 * 10^2) * (1.3 * 10^(-3)) = 6.8 * 1.3 * 10^2 * 10^(-3) = 8.84 * 10^(-1) = 8.84 * 0.1 = 0.884
Answer:
a) 0.071
b) 0.884
Step-by-step explanation:
b) explanation
Group coefficients together and exponents together to multiply numbers in scientific notation.
(6.8 ⋅ 1.3) (10^2 ⋅ 10^−3)
Multiply 6.8 by 1.3
8.84 (10^2 ⋅ 10^−3)
Use the power rule a^m a^n = a^m+n to combine exponents.
8.84 ⋅ 10^2 − 3
Subtract 3 from 2
8.84 ⋅ 10^ − 1
Convert 8.84 ⋅ 10^ − 1
from scientific notation.
0.884

the fastest 3 runners in a race qualify for the next event. how many different groups of Runners could advance to the next event from a race that has seven runners
Answers
Answer:
35 different groups of 3 runners can be selected
Step-by-step explanation:
Here, we want to simply calculate the number of 3 runners that can advance in a race from a total of 7
What we want to do here is to simply get different groups of 3
So, we have it that we simply want to know the number of different ways we can select 3 from a total of 7
We can simply use combination for this;
We have the general combinatorial as;
nCr = n!/(n-r)!r!
With respect to this particular question, n = 7 and r = 3
So we have;
7C3 = 7!(7-3)!3! = 7!/(4)!3! = 35

Nate is exponentially gaining Twitter followers! His current amount of followers is 146. His followers are increasing at a 24% rate each day. Part 1: Is this a growth or decay problem? ( 1 point) Part 2: Which equation correctly represents this problem (2 points) A) y=146(24)x B) y=146(1.024)x C) y= 146(1.24)x
Answers
Answer:
(a) Growth
[tex](b)\ y = 146(1.24)^x[/tex]
Step-by-step explanation:
Given
[tex]a= 146[/tex] -- current
[tex]r = 24\%[/tex] --- rate
Solving (a): Growth or decay
The question says his followers increases each day by 24%.
Increment means growth.
Hence, it is a growth problem
Solving (b): Equation to represent the scenario.
Since the rate represents growth, the equation is:
[tex]y = a(1 + r)^x[/tex]
Substitute: [tex]a= 146[/tex] and [tex]r = 24\%[/tex]
[tex]y = 146 * (1 + 24\%)^x[/tex]
[tex]y = 146 * (1 + 0.24)^x[/tex]
[tex]y = 146 * (1.24)^x[/tex]
[tex]y = 146(1.24)^x[/tex]

Do you mean that you want to create a distributive statement with 1/2 on the outside and a sum of 2 terms on the inside of a set of brackets? That's pretty wordy, but I mean something like
1/2 (x + a)
1/2*a = 3/5 Multiply both sides by 2.

10x−2y+2y=8+2y
10x=2y+8
