Since the total number of songs is 46,

g + d = 46

This is the first equation.

Since the guitarist wrote 8 less than twice the number of songs written by the drummer,

g = 2d - 8

This is the second equation.

Therefore, the answer is F.

<h3>Answer:</h3>

2 seconds

<h3>Explanation:</h3>

Equation: g(x) = -16x² + 64x + 80

<u>In order to find the maximum</u>:

vertex : -b/2a

= -64/2(-16)

= -64/-32

= 2

Maximum Height:

= -16(2)² + 64(2) + 80

= 144 ft

suppose an architect draws a segment on a scale drawing with the end points (0,0) and (3/4,9/10). the same segment on the actual

dlinn [17]

Let the segment be represented by AB where A(0,0) = $A(x_{1}, y_{1})$ and B(3/4,9/10) = $B(x_{2}, y_{2})$ .

The length of the segment drawn by architect can be calculated using distance formula:

AB = $\sqrt{}( x_{2}- x_{1})^ {2} + (y_{2}- y_{1})^ {2}$

$AB=\sqrt{(3/4-0)^{2}+(9/10-0)^{2}$

$AB=\sqrt{9/16+81/100} \\$

$AB = (6\sqrt{61})/40$

Similarly, Let the actual end points of segment be AC where A(0,0) = $A(x_{1}, y_{1})$ and C(30,36) = $C(x_{2}, y_{2})$ .

The length of the original segment can be calculated using distance formula:

AC = $\sqrt{}( x_{2}- x_{1})^ {2} + (y_{2}- y_{1})^ {2}$

$AC=\sqrt{(30-0)^{2}+(36-0)^{2}$

$AC=\sqrt{900+1296} \\$

$AC = (6\sqrt{61})$ .

Thus, the actual length is 40 times the length of the segment drawn by the architect.

Thus, the proportion of the model is 1:40
