Answer:

  (a)  8

  (b)  16

  (c)  24

  (d)  The ratios are the same

Step-by-step explanation:

(a) For inputs -5 and -4, the difference of outputs is ...

  -3 -(-11) = 8

__

(b) For inputs 0 and 2, the difference of outputs is ...

  45 -29 = 16

__

(c) For inputs -3 and 0, the difference of outputs is ...

  29 -5 = 24

__

(d) The ratios of output difference over input difference are ...

  8/1 = 16/2 = 24/3 = 8 . . . . . they are all the same

This is yet another confirmation that the slope of a line is the same everywhere, and over any interval.

Solve for x. Round to the nearest tenth, if necessary.
Brilliant_brown [7]

Answer:

x = 63.9

Step-by-step explanation:

We have:

\frac{QR}{sin35} = \frac{78}{sin90}

=> QR × sin90 = 78 × sin35

=> QR × sin90 = 44.7

=> QR = 44.7

But, we also have: x^{2} + QR^{2} = 78^{2} <=> x^{2} + 44.7^{2} = 78^{2} <=> x^{2} = 6084 - 1998.09

=> x^{2} = 4085.91

=> x = \sqrt{4085.91} = 63.9211.. = 63.9

<3 Have a nice day!!
