There's ambiguity here.  Either the original expression is "5 times the square root of a" or 5 is the "index of the root."

Then "5 times square root of a" would be  5a^(1/2), or
     1/2
5a


.  On the other hand, if you meant 5 to be the "index of the root," then the correct result would be

  1/5
a



If you're left unsure of which answer is correct, try copying the original problem onto paper and then writing out the answer you believe is correct.  Upload this image to Brainly and then attach it to your question.

Solve the equation for x by graphing -2x + 3 = -3(-x) - 2
adoni [48]

Answer:

  x = 1

Step-by-step explanation:

There are a couple of ways to solve this. One is to graph the left side of the equation, graph the right side of the equation, and look for the point where those graphs intersect. It is at x = 1. The first attached graph shows this solution.

__

Another method for solving such an equation is to subtract one side from the other and look for the value of x that makes the resulting expression zero.

  (-2x +3) -(-3(-x) -2) = 0

A graphing calculator doesn't need to have this simplified. If it is simplified, it becomes ...

  -5x +5 = 0

So, the graphed line is y = -5x+5. Its x-intercept is x=1, the solution of the original equation. The graph of this is shown in the second attachment.

What is the probability of selection for any man in a proportionate random sample, where a sample of 100 will be drawn from a po
kolbaska11 [484]
Working Principle: Stratified Random Sampling

nx = (Nx/N)*n

where:
    nx = sample size for stratum x
    Nx = population size for stratum x
    N = total population size 
    n = total sample size

Given:

  Nx = 100
  N = 1000
  n = 0.5*(1000) = 500

Required: Probability of Man to be selected

Solution:

nx = (Nx/N)*n
nx = (100/1000)*500 = 50 men

ny = (Nx/N)*n
ny = (100/1000)*500 = 50 women


Probability of Man to be selected = nx/(nx + ny)*100 = 50/(50+50)*100 = 50%

<em>ANSWER: 50%</em>

Miguel deposits $5000 in an account
jeyben [28]

Then the amount of money will he have in his account after 10 years will be $7,454.16. Then the correct option is B.

<h3>What is compound interest?</h3>

Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

Miguel deposits $5000 in an account earning 4% interest compounded monthly.

Then the amount of money will he have in his account after 10 years will be

We know the compound interest formula.

A = P (1 + r)^t

Where

A = amount

P = principal

r = rate of interest

t = time period (in year)

Then we have

\rm A = 5000 (1 + 0.04)^{10}\\\\A = 5000 (1.04)^{10}\\\\A = \$ \ 7454.16

More about the compound interest link is given below.
