Answer:

3 3/4 or 3.75 hours.

Step-by-step explanation:

If you need to travel 300 km, assuming you are going at the speed limit, you take the total amount and divide it by that.

300 / 80 = 3.75 hours

Answer:

$\frac{sin (c)}{AB}=\frac{sin(A)}{26}$

$sin(A)=\frac{26\times sin(13)}{6} =0.97$

$A=sin^{-1}(0.97)=\boxed{77^o}$

G(n)=-50-15n(n)=−50−15n, Complete the recursive formula of g(n)

UkoKoshka [18]

Answer:

g(1) = -65; g(n) = g(n-1) -15

Step-by-step explanation:

Using n = 1, 2, 3, we can find the first three terms of the sequence:

g(1) = -50 -15 = -65

g(2) = -50 -15(2) = -80

g(3) = -50 -15(3) = -95

The first term of the arithmetic sequence is -65, so that is g(1). Each next term is 15 less than the one before, so the recursive formula is ...

g(n) = g(n-1) -15

The complete recursive function definition requires both parts:

g(1) = -65

g(n) = g(n-1) -15

The function rule C = 40n + 210 relates the number of months n to cost in dollars C of a phone plan and budget phone. Make a tab

Viefleur [7K]

Answer:

Input - Output

2 - $290

12 - $690

24 - $1170

Step-by-step explanation:

Cost after n months:

The cost after n months is given by the following function:

$C(n) = 40n + 210$

After 2 months:

This is C(2). So

$C(2) = 40(2) + 210 = 80 + 210 = 290$

After 12 months:

This is C(12). So

$C(12) = 40(12) + 210 = 480 + 210 = 690$

After 24 months:

This is C(24). So

$C(24) = 40(24) + 210 = 960 + 210 = 1170$

Table:

Input - Output

2 - $290

12 - $690

24 - $1170
