Evaluate the limit assuming that limx→−5f(x)=17limx→−5f(x)=17 and limx→−5g(x)=22limx→−5g(x)=22. (use symbolic notation and fract
Gemiola [76]

In this question it is given that

\lim_{x->-5}f(x)=17, \lim_{x->-5}g(x)=22

And we have to find the value of the given limit

\lim_{x->-5}(23f(x)+3g(x))

Using properties of limit, first we separate the two functions, that is

23\lim_{x->-5}f(x)+3\lim_{x->-5}g(x)

Substituting the values of the given limit,

23(17)+3(22)=457

At best buy they have a 42" TV that sells for $1250 and is on sale for 15% off. What
marysya [2.9K]

Answer:

If the television is on sale for 15%, that means that the selling price before tax will be 100 - 15 = 5% of the original price.

1250 * 0.85 = $1062.5 ... this is your selling price BEFORE tax

Now, calculate your tax.

You would pay (1062.5) + (1062.5 * 0.065)  

= 1062.5 + 69.06 (your tax)

= 1131.56 dollars

M is directly proportional to r2 <br> When r=2, m=14<br> Work out the value of m when r=12
Genrish500 [490]

we have M is durectly porpotional to r^2

so M=(k)r^2

and when r=2, m=14

so 14=(k)(2)^2

k=14/4 =7/2

so when r=12

m= (7/2)(12)^2 =(7/2)(144) = 504
