Nate works at least 4 hours but not more than 9 hours. He earns $12.40 per hour. The function f(t) = 12.4t represents the amount
Mashcka [7]

The practical domain is all real numbers from 4 to 9, inclusive.

The practical range is all real numbers from 49.6 to 111.6, inclusive.

These are the correct options.

Explanation:

Given function is f(t) = 12.4t

Let us assume that Nate works 'x' hours so 4<x<9

And multiplying the hours with his earnings we get the range.

4*12.40=49.6 and 9*12.40=111.6. Let the amount earned be represented by y

Hence, domain can be represented as 4<x<9 and range can be represented as  49.6 < y < 111.6

In quadrilateral QRST, Angle R S T measures (5x+15)°. Angle TQR measures (4x+3)°.
ANTONII [103]

Answer:

RST= 105 degrees

Step-by-step explanation:

it would be 2(5x+15) + 2(4x+3) =360

10x+30+8x+6=360

18x=324

x=18

so RST=5x+15=5(18)+15=105
