Answer:

x = - 8, x = 6

Step-by-step explanation:

{x}^{2}  + 2x - 48 = 0 \\  \\  {x}^{2}  + 8x - 6x - 48 = 0 \\  \\ x(x + 8) - 6(x + 8) = 0 \\  \\ (x + 8)(x - 6) = 0 \\  \\ x + 8 = 0 \:  \: or \:  \: x - 6 = 0 \\  \\ x =  - 8, \:  \:  \:  \: x = 6 \\

A boat has a speed of 9 mph in calm water. It takes the boat 4 hours to travel upstream but only 2 hours to travel the same dist
Dmitrij [34]
D=4(9-c) and d=2(9+c)

d=36-4c and d=18+2c

Since d=d

18+2c=36-4c  add 4c to both sides

18+6c=36  subtract 18 from both sides

6c=18  divide both sides by 6

c=3

So the speed of the current is 3mph

Find the probability of at least 2 girls in 8 births. assume that male and female births are equally likely and that the births
Afina-wow [57]
At least two girls means either 2, 3 ... or 8 girls. 
Using the binomial law, we can write the probability in the form:
B(2,0.5)+B(3,05)+...+B(8,0.5)=0.0039(C_8^2+...+C_8^8)
Continue simplifying:
C_8^2+...+C_8^8=2^8-C_8^1=2^8-8=248\\\text{We deduce the probability of the event "at least two girls in birth ":}\\0.0039\times248=0.96\\\text{The above probability (0.96) means that the event is very likely}

Given f(x)=3^(x-2) and g(x)=f(3x)+4, write the function rule for function g and describe the types of transformations that occur
Liono4ka [1.6K]

Answer:

The function g(x) is 3^{3x - 2} + 4 and this is Translation Transformation .  

Step-by-step explanation:

Given as :

The two functions f(x)  and  g(x) is as given

Function f(x) = 3^{x - 2}

And        g(x) = f(3 x) + 4

Now, for x = 3 x

The function f(x) can be written as

f(3 x) =  3^{3x - 2}

So, g(x) =    3^{3x - 2} + 4

<u>While plotting the function f(x)  and  g(x)  on the graph , the points translate from one to other quadrant , so this is a type of TRANSLATION TRANSFORMATION . </u>

Hence The function g(x) is 3^{3x - 2} + 4 and this is Translation Transformation .    Answer

given data

mints $0.96 per pound

chocolates $4.70 per pound

lollipops $0.07 each

cost of each items based on the amount item

mints $0.96*0.75= 0.72

chocolates $4.70*1.5=7.05

lollipops $0.07*15=1.05

total cost= 0.72+7.05+1.05

total cost=$8.82
