<u>Answer</u>

0


<u>Explanation</u>

9/(n²+1)=(n+3)/4

9/(n²+1) = (n+3)/4

(9 × 4)/(n²+1) = n+3

36/(n² + 1) = (n + 3)

36 = (n²+1)(n+3)

36 = n³+3n²+n+3

n³ + 3n² + n - 33 = 0

This is a cubic function and so, it have 3 solutions.

No extraneous solutions.

A fish jumps out of the water at a speed of 12 feet per second. The height y (in feet) of the fish above the surface of the wate
sasho [114]

Answer:

The fish is 2.25 ft above the surface at 0.375 seconds

Step-by-step explanation:

Given:

y=-16x^2+12x

x=0.375 seconds

Substitute x=0.375 into the equation

y=-16x^2+12x

= -16(0.375)^2 +12(0.375

= -16(0.140625) + 4.5

= -2.25 + 4.5

= 2.25

y=2.25 ft

The fish is 2.25 ft above the surface at 0.375 seconds

The slope of a line passing through H (-2, 5) is -3/4. Which ordered pair represents a point on this line?
oksano4ka [1.4K]
Answer:
(6,-1)

Explanation:
The slope of the line can be calculated using the following formula:
slope = \frac{y2-y1}{x2-x1}

We are given that:
slope = -0.75
point (x1,y1) is (-2,5)

We will use each of the given points to calculate the corresponding slope, then compare the calculated slope with the given one.

For point (6,-1):
slope = \frac{-1-5}{6--2} = -0.75 ........> accepted choice

For point (2,8):
slope = \frac{8-5}{2--2} = 0.75 ........> rejected choice

For point (-5,1):
slope = \frac{1-5}{-5--2} = 4/3 ........> rejected choice

For point (1,1):
slope = \frac{1-5}{1--2} = -4/3 ........> rejected choice

Therefore, the first option is the only correct one.

Hope this helps :)
