A set of numbers having 4 in the unit place from 1 to 50

{4, 14, 24, 34, 44}

Step-by-step explanation:

A general number can be written as:

aₙ*10ⁿ + ... + a₂*10² + a₁*10¹ + a₀*10⁰ + a₋₁*10⁻¹ ...

Where the a₁ coefficient is the "unit" of a number.

For example, the number 145.2 can be written in this form as:

1*10² + 4*10¹ + 5*10⁰ + 2*10⁻¹

Then the numbers having a 4 in the unit place, will be the numbers that have the digit 4 just at the left of the decimal point.

the set of natural numbers having 4 in the unit place, that also are between 1 and 50 are:

{4, 14, 24, 34, 44}

step-by-step explanation:

∠cbe and ∠deb are same-side interior angles

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
