A person buys X meter for 5
Nady [450]

Step-by-step explanation:

I guess, it means every meter costs these amounts.

and the specified costs are not fit the whole bundle.

it is also unclear, if "half of it" means half of the original x meters, or half of the remaining meters (after selling 2/5 of the original meters). I assume the first.

so, we have

-5x

+ 2/5x × 5.5

+ 1/2x × 6.4

+ (10/10 - 4/10 - 5/10)x × 6 = + 1/10x × 6

= 120 ( a income minus costs is the profit, so balancing both sides in a "+" and "-" expression gives us the remaining profit).

about the line with the 1/10 :

the leftovers. 10/10 is the whole x at the beginning.

2/5 = 4/10.

1/2 = 5/10.

I brought all involved fractions to the same denominator of the smallest common multiple of 2 and 5 (10).

in full

-5x + (2/5)x×5.5 + (1/2)x×6.4 + (1/10)x×6 = 120

-5x + 2.2x + 3.2x + 0.6x = 120

-5x + 6x = 120

x = 120

so, he bought 120m in the first place.

f(x) = −16x2 + 24x + 16 Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points) WILL GIVE BRAINLIEST
castortr0y [4]

Answer:

Step-by-step explanation:

f(x) = −16x2 + 24x + 16 = 0 can be reduced to -2x^2 + 3x + 2 = 0 and then to 2x^2 - 3x - 2 = 0.  Solve this for x using the quadratic formula:

The discriminant is b^2 - 4ac = (-3)^2 - 4(2)(-2) = 9 + 16 = 25.

Therefore the roots are:

     -(-3) ± √25        3 ± 5

x = ----------------- = ------------  =>  x = 2 and x = -1/2

           2(2)                  4

The x-intercepts are points:  (2, 0) and (-1/2, 0)

Because the coefficient of the x^2 term is negative, this graph opens down and the vertex represents a maximum.

To graph this function, find and plot the vertex.  It is exactly halfway between the x-intercepts, that is, at x = 1 1/4, for which the y value is 21:

vertex and maximum at (5/4, 21)

Finally, find the y-intercept.  Let x = 0; we find that y = 16.  The y-intercept is 0, 16)

We now have four points on the graph and know where the maximum is.  Plot this max (5/4, 21) and the x-intercepts (2, 0) and (-1/2, 0), and finally the y-intercept.  Draw a smooth curve through these points, remembering that the graph is symmetrical about the axis of symmetry x = 5/4.

Lerok [7]

Answer:

See below

Step-by-step explanation:

  • <em>Bi-conditionals are represented by the symbol ↔ or ⇔ </em>
  • <em> p↔q means that p→q and q→p </em>

<u>Bi-conditional statement:</u>

  • A rectangle is a square if and only if all four sides of the rectangle have equal length.

<u> The associated conditional statements are: </u>

  • a) If all sides of a rectangle are equal then it is a square.
  • b) If a rectangle is a square then all sides have equal length.
