75-31= 44
44/75= 0.58666 or 58.7%

Subtract 31 from 75 since we're figuring out greater than or "equal to" we want to include the number 32 in our equation. If it was only "greater than" 32 then we'd subtract 32 from 75. Then you divide that number(44) by 75, which is all the possible outcomes you could have in this scenario. Move the decimal two places to the right to make it a percentage and you've got your answer.

The quotient of 9.2 x 10 6 and 2.3 x 10 2 expressed in scientific notation is
Virty [35]
What we know:
quotient 9.2 x 10^6/ 2.3 x 10²
in quotients exponents are subtracted of they have the same base, for example 10^6 and 10² have the same base of 10

What we need to find: quotient 9.2 x 10^6/ 2.3 x 10²
9.2 x 10^6        
--------------  =    4 x 10^4    
 2.3 x 10²

Here in this problem I divided 9.2 by 2.3 and got 4, since the solution was simple and clean meaning no repeated decimals I went ahead and divided the 10^6 by 10^2 and got 10^4.


Another method would be to expand both numbers then divide and do scientific notation again.
Remember to change to normal notation you move the decimal to the right using the number of the exponent.

9.2 x 10^6= 9200000
2.3 x 10²= 230

920000/230=40000

40000= 4 x 10^4 scientific notation

Use the method that is best for you or just know you can use either method to check your work.

Can someone explain?

The correct statement regarding the quadratic function is:

K. I, II and III.

<h3>What is a quadratic function?</h3>

A quadratic function is given according to the following rule:

y = ax^2 + bx + c

If a > 0, it has a maximum value, and if a < 0, it has a minimum value.

The extreme value is (x_v,y_v), in which:

  • x_v = -\frac{b}{2a}
  • y_v = -\frac{\Delta}{4a}
  • \Delta = b^2 - 4ac

The solutions are:

  • x_1 = \frac{-b + \sqrt{\Delta}}{2a}
  • x_2 = \frac{-b - \sqrt{\Delta}}{2a}

In this problem, we have a function h(t). Changing the coefficient c, the h-intercept h(0) changes. Looking at the formulas in the bullet point, the value of \Delta changes, meaning that both the maximum value y_v and the t-intercepts t_1 and t_2 will change, so option K is correct.

Which linear inequality represents the graph below?
muminat

Answer:

The answer would be B

Step-by-step explanation:

The reason that we know this is because the line is falling and because it is a solid line then we know that it is ≥ and not just >.  the solid line already gets rid of C and D.  A is a positive number which would cause the line to go the opposite direction.  Therefore B is your only answer left.
