Rai compares two cable plans from different companies. Which equation gives the correct value of m, the number of months for whi
tekilochka [14]

Answer:

D. 75m = 50(12)+125(m-12)

Step-by-step explanation:

m = months.

Equation for which Plans A and B cost the same.

In Plan A:

No initial fees.

$75 per month

1 month = $ 75

then;

for m month =$75 m

Total cost for plan A =  75m

In Plan B:

$50 per month for first 12 month.

1 month = $50

12 months = 50(12)

Similarly,

$125 per month for each additional month after that.

additional month= (m-12)

Plan B additional month

= 125(m-12)

Total cost for plan B = 50(12)+ 125(m-12)

Since, Plans A and B cost the same.

75m = 50(12)+125(m-12)

Ginny is studying a population of frogs. She determines that the population is decreasing at an average rate of 3% per year. Whe
svp [43]

Answer:

Step-by-step explanation:

This is exponential, of the form

y=a(b)^x where a is the initial amount and b is the growth/decay rate. If Ginny begins the study with 1200 frogs in the population, our a value is 1200.

If the population is decreasing 3% per year, it is decreasing 100% - 3% = 97% which, as a decimal, is .97. Our exponential function, then, is

y=1200(.97)^x

Pls help me before I have another mental breakdown
Lyrx [107]

Answer:

a) fog(x) = (x-2)⁴ +4

b) (g o f) (x) = x⁴ + 2

c) hog(x) = \sqrt{x-2}

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the function

f(x) = x⁴+4 , g(x) = x-2 , h(x) = √x

f o g (x) = f(g(x))

           = f(x-2)

         = (x-2)⁴ +4  (∵ f(x) = x⁴ +4))

fog(x) = (x-2)⁴ +4

<u><em>Step(ii):-</em></u>

(g o f) (x)  = g(f(x))

              = g(x⁴ +4)

             =  x⁴ +4 -2   ( ∵ g(x) = x-2)

            = x⁴ + 2

(g o f) (x) = x⁴ + 2

<u><em>Step(iii)</em></u>:-

hog(x) = h(g(x))

         = h(x-2)

         =  \sqrt{x-2}    

 hog(x) = \sqrt{x-2}

How do you (experimentally) find the surface area of a pear?​
Lana71 [14]

Answer:

That's like saying "How do you (hypothetically) write a letter?"

Step-by-step explanation:

But you would probably have to measure the length, height, and width of this experimental pear and go from there.

Then plug your length, width, and height into your surface area formula.

It is also important to know where in the pear you are measuring. The top of the pear will have different measurements than the middle.
