Following with the extra hint that x = 82.03 m

There are 2 ways to approach the question, but although I prefer to group up x first before plugging value, having that -0.05x^2 to group up is too annoying:

Plug x = 82.03

=> Y = -0.05*(82.03^2) + 4.5*82.03 - 6.5
         = -336.446045 + 369.135 - 6.5
         = 26.188955 m

Please take the time and understand the answer instead of just looking at the final result.

Also I know the number is very long, but that's the question's fault. <span>¯\_(ツ)_/¯</span>

Find the equivalent ratio, write proportion for 12:10
gogolik [260]

Answer:  6:5

Step-by-step explanation:  You can simplify the ratio 12 : 10 by dividing both terms by the greatest common factor (GCF)

The GCF of 12 and 10 is 2.

Divide both terms by 2.

12 ÷ 2 = 6

10 ÷ 2 = 5

ANSWER:

12 : 10 = 6 : 5

Find the equation of the line through (-4,-1) and parallel to y = -1/2x +1 in slope-
Alex17521 [72]

Step-by-step explanation:

Let the equation of the line be y = mx + c

since the line is parallel to y = -1/2x + 1, the two lines have the same gradient.

therefore, m = -1/2

sub (-4, -1):

-1 = -1/2(-4) + c

c = -3

therefore equation of the line is y = -1/2x - 3

This question demands knowledge on coordinate geometry's slope intercept form and finding unknowns. If you would like to venture further, you can check out my Instagram page (learntionary). Thanks!
