No, it is not, a parabola, (from this equation, which is x^2, disregarding the +8 or y-intercept) cannot be a one-to-one function, it is a many-to-one.

Fine the slope of the line passing through the points
Elodia [21]

slope is zero for both of them. Why?

Since slope, m = rise/run

which is  m = (y2-y1)/(x2-x1)

since y2-y1 is zero for both cases and zero divided by any number is zero therefore the slope is zero for both. hope this helps!

You normally pay your line cooks $22 per hour, but one has worked overtime and should be paid time and a half. What is
GalinKa [24]

Answer:

  $33 per hour

Step-by-step explanation:

"Time and a half" means the overtime rate is 1 1/2 times the base rate.

  overtime rate = (1 1/2) × $22/hour = $(22 +1/2(22))/hour = $33/hour

The correct overtime rate is $33 per hour.

<h3>#7 </h3>
  • -94% = -0.94
  • -.925 = -0.925
  • -8/9 = - 0.888
  • -9/10 = - 0.9

<u>Ascending order:</u>

  • - 0.94 < -0.925 < -0.9 < -0.888 or
  • -94% < -0.925 < -9/10 < - 8/9
<h3>#8</h3>
  • √170 ≈ 13.038
  • 13.5
  • 64/5 = 12.8
  • 13 7/8 ≈ 13.875

<u>Decreasing order:</u>

  • 13.875 > 13.5 > 13.038 > 12.8 or
  • 13 7/8 > 13.5 > √170 > 64/5

Papessa [141]

Answer:

23 days

Step-by-step explanation:

Given that the mass of a particular substance is known to grow exponentially at a rate of 1.5% per day

Initial mass = 230 gm

After t days, mass = 325 gm

The equation is

P(t) = 325 = 230 (1+\frac{1.5}{100} )^t\\\frac{325}{230} =1.015^t\\log 1.413 = t log 1.015\\t = \frac{log 1.413}{log 1.015} =\frac{0.1502}{0.0065} \\=23.229

Approximately after 23 days the mass will become 325 gms.
