Given that [tex] \angle{SUR} = 42°[/tex] is a subtended central angle by two diameters,

Step-by-step explanation:

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]

1/2x + 3/5 as the product of a constant and sum of terms

Answers

Answer:

Step-by-step explanation:

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.

a = 2 * 3/5

a = 6/5

Answer:

x= 1 /5 y+ 4 /5

Step-by-step explanation:

Let's solve for x.

10x−2y=8

Step 1: Add 2y to both sides.

10x−2y+2y=8+2y

10x=2y+8

Step 2: Divide both sides by 10.

10x /10 = 2y+8 /10 x= 1 /5 y+ 4 /5

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
