What proportion of the first 10,000 natural numbers contain a 3
Sergeeva-Olga [200]
In the first 10 -> 10 - 9 = 1 (contain a 3).
In the first 100 -> 100 - 9 * 9 = 19 (contain a 3).
In the first 10^n -> 10^n - 9^n  (contain a 3).




So for 10^4 -> 10^4 - 9^4 = 10.000 - 6.561 = 3.439 


<u>The answer is 3.439 numbers contain a 3 in the first 10.000</u>

Please give me correct answer and fast answer it if know answer only
Stolb23 [73]

Answer:

Approximatley 5.8 units.

Step-by-step explanation:

We are given two angles, ∠S and ∠T, and the side opposite to ∠T. We need to find the unknown side opposite to ∠S. Therefore, we can use the Law of Sines. The Law of Sines states that:

\frac{\sin(A)}{a}=\frac{\sin(B)}{b} =\frac{\sin(C)}{c}

Replacing them with the respective variables, we have:

\frac{\sin(S)}{s} =\frac{\sin(T)}{t} =\frac{\sin(R)}{r}

Plug in what we know. 20° for ∠S, 17° for ∠T, and 5 for <em>t</em>. Ignore the third term:

\frac{\sin(20)}{s}=\frac{\\sin(17)}{5}

Solve for <em>s</em>, the unknown side. Cross multiply:

\frac{\sin(20)}{s}=\frac{\sin(17)}{5}\\5\sin(20)=s\sin(17)\\s=\frac{5\sin(20)}{\sin(17)} \\s\approx5.8491\approx5.8

investments historically have doubled every 9 years. If you start will a $2,000 investment, how much money would you have after
azamat

Answer:

$64,000

Step-by-step explanation:

Friday, 45 / 9 = 5

So the investment will double 5 times

First time

2,000 (starting investment) × 2 = 4000

Second time

4000 × 2 = 8000

Third time

8000 × 2 = 16000

Fourth time

16000 × 2 = 32000

Fifth and final time

32000 × 2 = 64000

$64,000

Multiply the polynomials (x+3)(2x−4). What is the product in the form ax^2+bx+c?
Romashka [77]

Answer:

Step-by-step explanation:

In the same way as you could factor trinomials on the form of

x2+bx+c

You can factor polynomials on the form of

ax2+bx+c

If a is positive then you just proceed in the same way as you did previously except now

ax2+bx+c=(x+m)(ax+n)

wherec=mn,ac=pqandb=p+q=am+n

Example

3x2−2x−8

We can see that c (-8) is negative which means that m and n does not have the same sign. We now want to find m and n and we know that the product of m and n is -8 and the sum of m and n multiplied by a (3) is b (-2) which means that we're looking for two factors of -24 whose sum is -2 and we also know that one of them is positive and of them is negative.

Factorsof−24−1,241,−24−2,122,−12−3,83,−8−4,64,−6Sumoffactors23−2310−105−52−2

This means that:

3x2−2x−8=

=3x2+(4−6)x−8=

=3x2+4x−6x−8

We can then group those terms that have a common monomial factor. The first two terms have x together and the second two -2 and then factor the two groups.

=(3x2+4x)+(−6x−8)=

=x(3x+4)−2(3x+4)

Notice that both remaining parenthesis are the same. This means that we can rewrite this using the distributive propertyit as:

=(x−2)(3x+4)=3x2−2x−8

This method is called factor by grouping.

A polynomial is said to be factored completely if the polynomial is written as a product of unfactorable polynomials with integer coefficients.
