Answer: 7. g = -50, 8. f= 340/6 9. 3 10 .125

Step-by-step explanation:#7 g(3): 4(3)^2 +6 =12^2 +6 = 1444=6= 150. We divide 150 by 3 giving us -50.  #8We start by putting f(6): -3(6)^2 -4(6) +8. We use PEMDAS. -18^2 -24 +8 = _324-24+8 F= 340/6 #9 g(15) = Square root of 15-6=9 and the square root of 9 is 3, therefore, the answer is 3. #10 h (x) = 2^x we plug -3 to 2^-3. It is a negative number and it gives us .125 or 12.5

  • Answer:

<em />

<em>7. g(3) = 42</em>

<em>8. f(6) = - 124</em>

<em>9. g(15) = 3</em>

<em>10. h(-3) = 1/8</em>

  • Step-by-step explanation:

<em></em>

<em>7.</em><em> g(x) = 4x² + 6</em>

<em>g(3) = 4×3² + 6</em>

<em>= 4×9 + 6</em>

<em>= 36 + 6</em>

<em>= 42</em>

<em />

<em>8.</em><em> f(x) = - 3x² - 4x + 8</em>

<em>f(6) = - 3×6² - 4×6 + 8</em>

<em>= - 3×36 - 24 + 8</em>

<em>= - 108 -16</em>

<em>= - 124</em>

<em />

<em>9. </em><em>g(x) = √(x - 6)</em>

<em>g(15) = √(15 - 6)</em>

<em>= √9</em>

<em>= 3</em>

<em />

<em>10. </em><em>h(x) = 2ˣ</em>

<em>h(-3) = 2⁻³</em>

<em>= 1/2³</em>

<em>= 1/8</em>

18 of the 47 people surveyed said they were not interested in trying a sample of a new soft drink. Find probability that a rando
vovangra [49]

Answer: 0.62

Step-by-step explanation:

Total people= 47

Let A be the event of selecting person was interested in trying the new drink.

Person not interested in trying a sample of a new soft drink (nA')=18

Person interested in trying a sample of a new soft drink (nA)=47-18=29

Thus probability that a randomly selected person was interested in trying the new drink

P (A) = 29/41 = 0.6170 (or) 0.62

Thus, probability that a randomly selected person was interested in trying the new drink is 0.62.

47-18=29 people interested in the new drink

29/47=0.617

0.617*100=61.7% chance

The cost, £C, of hiring a lorry to travel n miles is given by
zysi [14]
Part A:
C= a + bn

Make the two equations out of the words:
82 = a + b100 * 2.5     = 205 = a + b250
157 = a+ b250

Subtract the two,
205 = a + b250
- ( 157 = a + b250)
48 = a

Find b by substituting in a:
82 = a + b100
82 = 48 + b100
34 = b100
b = 0.34
Answer for part a: a = 48 , b = 0.34

Part B:
C = a +bn    <- when n = 300   , put in a and b, then solve
C = 48 + 0.34(300)
C = 48 + 102
C = 150

Cost when hiring a lorry to travel 300 miles is 150 pounds
