Answer:

10x^3 - 34x^2 + 33x - 7

Step-by-step explanation:

Multiply each term of the trinomial by each term of the binomial. Then combine like terms.

(2x^2 - 4x + 1)(5x - 7) =

= 10x^3 - 14x^2 - 20x^2 + 28x + 5x - 7

= 10x^3 - 34x^2 + 33x - 7

Answer:  10x³ -34x² +33x - 7

<u>Step-by-step explanation:</u>

 (2x² - 4x + 1)(5x - 7)

= (5x - 7)(2x² - 4x + 1)

= 5x(2x² - 4x + 1)   -7(2x² - 4x + 1)

= 10x³ - 20x² + 5x    

<u>  +         -14x² + 28x - 7</u>

= 10x³ - 34x² + 33x - 7

29 — 6x=5(1 – 6x)<br> Please show me the steps
Lady bird [3.3K]

Answer:

x= -1

Step-by-step explanation:

<u><em>START</em></u> 29 - 6x = 5(1 - 6x)

1.  Distribute

29 - 6x = 5 - 30x

2. Isolate the variable

~ <u>2a</u>. Add 30x to both sides

29 - 6x + 30x = 5 - 30x + 30x

~ <u>2b</u>. Subtract 29 from both sides

29 - 29 - 6x + 30x = 5 - 29 - 30x + 30x

3. Simplify

24x = -24

4. Solve

x = -1

<em><u>END</u></em>

Taylor's computer randomly generate numbers between 0 and 4, as represented by the given uniform density curve.
MrRa [10]

12.5% is the percentage of numbers randomly generated by Taylor's computer that is less than 0.5.

An illustration of a numerical distribution with continuous results is a density curve. A density curve is, in other words, the graph of a continuous distribution. This implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete). As seen by the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).

The percentage of numbers randomly generated by Taylor's computer are less than 0.5 is given by

P(0≤X≤0.5)

=\int_{0}^{0.5}\frac{1}{4}dx

=\frac{1}{4}x|^{0.5}_{0}

=\frac{1}{4}(0.5-0)

=0.25(0.5)

= 0.125

That is 12.5%
