Answer:

Linear, the linear term is -21x and the constant term is -20. Last option is the answer

Step-by-step explanation:

We are given the following function:

$y = (x - 5)(5x + 4) - 5x^2$

First we have to simplify y, before solving the question:

$y = (x - 5)(5x + 4) - 5x$

Applying the distributive property:

$y = 5x^2 + 4x - 25x - 20 - 5x^2$

$y = 0x^2 - 21x - 20$

$y = -21x - 20$

No quadratic term, so it is linear.

The linear term is -21x and the constant term is -20.

Answer:

Step-by-step explanation:

Given, 

$\frac{1}{ {6y}^{ - 2} }$

Since,

${x}^{ab} = {( {x}^{a} )}^{b}$

Hence,

$= \frac{1}{ {( {6y}^{2} )}^{ - 1} }$

Since,

$\frac{1}{ {x}^{ - 1} } = x$

Hence,

$= {6y}^{2} (ans)$

No woman has broken the 10-second barrier in the 100 -meter runfind probability the empirical probability that a womwn will brea

Anuta_ua [19.1K]

Let me help you!

What we have so far:
Number of times the event occured = 0
Total number of times the event was performed = 0

We will use the empirical probability formula for this problem:
Empirical probability formula = Number of times the event occured / Total number of times the event was performed

Solving for the porblem:
Empirical probability formula = 0.

*** Without even solving the problem, you can take the word "NO" as a hint that there's simply no chance any woman can beak the 10 seconds barrier in a 100 meter run.

Therefore, there is 0 probability that a woman will break the 10 seconds barrier in a 100 meter run.

Find the product and sum of the roots of the equation: 3x^2-10=0

cluponka [151]

● 3x^2 - 10 = 0

Add 10 to both sides

● 3x^2 - 10 + 10 = 10

● 3x^2 = 10

Divide both sides by 3

● 3x^2/3 = 10/3

● x^2 = 10/3

● x = √( 10/3 ) or x = - √( 10/3 )
