The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). What is m+n?

Answers

Answer 1

Answer:

the aswer is 32

Step-by-step explanation:

Answer 2

The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). the sum of m + n is 178/27.

To find the vertex of the parabola described by the equation 3y = 2x^2 - 16x + 18, we first need to put the equation in the standard form of a parabola, which is y = a(x - h)^2 + k, where (h, k) represents the vertex.

Let's begin by dividing the entire equation by 3 to simplify it:

y = (2/3)x^2 - (16/3)x + 6

Now, we need to complete the square to rewrite the equation in the form y = a(x - h)^2 + k:

y = (2/3)(x^2 - (8/3)x) + 6

Next, we need to find the value that completes the square for the expression inside the parentheses. To do that, we take half of the coefficient of x and square it:

(8/3) / 2 = 4/3

(4/3)^2 = 16/9

Now, we add and subtract 16/9 inside the parentheses:

y = (2/3)(x^2 - (8/3)x + 16/9 - 16/9) + 6

Now, we group the first three terms and factor the perfect square trinomial:

y = (2/3)((x - 4/3)^2 - 16/9) + 6

Next, distribute the (2/3):

y = (2/3)(x - 4/3)^2 - (2/3)(16/9) + 6

Now, simplify:

y = (2/3)(x - 4/3)^2 - (32/27) + 6

Finally, bring everything together:

y = (2/3)(x - 4/3)^2 + (142/27)

Now we can see that the vertex of the parabola is at the point (h, k) = (4/3, 142/27).

To find m + n, we simply add the x-coordinate (h) and the y-coordinate (k):

m + n = 4/3 + 142/27

To add these fractions, we need to find a common denominator, which is 27. Convert 4/3 to have a denominator of 27:

4/3 = (4/3) * (9/9) = 36/27

Now we can add the fractions:

m + n = 36/27 + 142/27

m + n = (36 + 142)/27

m + n = 178/27

Answer for 1st set:

m∠1=105° and m∠2=75°

Breakdown:

You're given one angle of 75°. That one angle is equal to m∠2. Since m∠2 is making a linear pair with m∠1, you take 180° (Straight line) and take 75° from it.

180-75=105

Answer for 2nd set:

m∠1=130° and m∠2=50°

Breakdown:

Using the same logic as before, linear pair, blah-blah-blah, you're given 130.

Answers

Answer:

yes since it grows at a constant rate at 7.5 feet/5 days so it should be proportional if you treat it as an algebraic equation and solve for the rate of 1 day's growth but that gives an assumption that no factors would affect the growth and it'll always grow at that exact rate

180 - 121 = 59
the sum of angles in a triangle is 180 so
180-59 = 121
the rest of the angles are going to sum up to 121 so
121=7x + (6x-9)
from here just do basic algebra
121+Q=180(exterior angle of triangle)
Q=180-121
Q=59

7x+6x-9+59=180(anglesum property)
13x+50=180
13x=130
x=10


6x-9=60-9
=51

7x=7*10
=70



Ans=59,70,51

Check:51+59+70=180
