Answer:

  • y = 6x + 90
  • 210 kg

Step-by-step explanation:

<u>This is a linear relationship:</u>

  • y = mx + b

<u>We have:</u>

  • m = 6 and a point (8, 138)

<u>Work out the y-intercept by using the above information:</u>

  • 138 = 6*8 + b
  • b = 138 - 48
  • b = 90

<u>The equation is:</u>

  • y = 6x + 90

<u>Find the value of y when x = 20:</u>

  • y = 6*20 + 90 = 120 + 90 = 210 kg

<u>Answer:</u>

  • The weight after 20 months is 210 kilos.

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

  • 1 month = 6 kilos
  • => 8 months = 6 x 8 = 48 kilos
  • => x + 48 = 138
  • => x = 90

<u>This means that the starting point is 90 kilos.</u>

  • => 1 month = 6 kilos
  • => 20 months = 6 x 20 kilos
  • => 20 months = 120 kilos
  • => 90 + 120 = weight in 20 months
  • => <u>210 kilos = weight in 20 months</u>

Hence,<u> the weight after 20 months is 210 kilos.</u>

If x2 - 6x - 16, what are the x-intercepts?​
romanna [79]
If that’s meant to be x^2 - 6x - 16
Then factorise to (x+2)(x-8)
So x intercepts are -2 and 8

Find the exponential function that satisfies the given conditions:
Nady [450]

Answer:

f(t) = 66·0.995^t

Step-by-step explanation:

You can try t=0 and t=1 in each of the formulas to see which one gives values of 66 and 0.5% less than 66, or 65.67.

The first function has an initial value of 0.5, so is not correct.

The second function gives f(1) = 99, so is not correct.

The third function gives f(1) = 65.67, so is correct.

The fourth function gives f(1) = 66.33, so is not correct.

_____

You can realize that the multiplier will be 0.5% less than 100%, so will be 99.5% = 0.995. This number shows up only in the third selection.
