If f(x) = 3x² - 4 and g(x)= x+2, find (f - g)(x).
evablogger [386]

Answer:

D.   3x² - x - 6

Step-by-step explanation:

If f(x) = 3x² - 4 and g(x)= x+2, find .

We know that (f - g)(x) = f(x) - g(x)

Then

(f - g)(x) = (3x² - 4) - (x+2)

            = 3x² - 4 - x - 2

            = 3x² - x - 4  - 2

            = 3x² - x - 6

In an ensemble of gongs, all gongs have a diameter of either ten inches, or twelve inches or fifteen inches. In the collection t
patriot [66]

Answer: Option 'E' is correct.

Step-by-step explanation:

Since we have given that

Let the total number of gongs be 'g'.

Number of ten inch gongs = 18

Let the number of 12 inch gongs be 'x'.

Let the number of 15 inch gongs be 'y'.

so, equation would be

18+x+y=g

Half of the gongs are tiger gongs is given by

t=\dfrac{g}{2}\\\\g=2t

Half of the 12 inch gongs are not tiger gongs

so, number of tiger gongs which is of 12 inch = \dfrac{x}{2}

Among the tiger gongs, there are equal numbers of ten inch, twelve inch and fifteen inch.

\dfrac{x}{2}+\dfrac{x}{2}+\dfrac{x}{2}=t\\\\\dfrac{3x}{2}=t

Half of the gongs are of 15 inch is given by

y=\dfrac{g}{2}\\\\2y=g

Since we have

g=2t\\\\g=2\times \dfrac{3x}{2}\\\\g=3x\\\\\dfrac{g}{3}=x

so, According to question, it becomes,

18+\dfrac{g}{2}+\dfrac{g}{3}=g\\\\18+\dfrac{5g}{6}=g\\\\18=g-\dfrac{5g}{6}\\\\18=\dfrac{6g-5g}{6}=\dfrac{g}{6}\\\\18\times 6=g\\\\108=g

Hence, Option 'e' is correct.

Answer: 126cm, 136.5cm, 147cm, 144cm, 100cm

Step-by-step explanation: 5% increase is the same as multiplying by 1.05, and to do it in reverse you divide instead.

120*1.05=126cm

130*1.05=136.5cm

140*1.05=147cm

151.2/1.05=144cm

105/1.05=100cm
