Determine the slope of the line that has the following coordinates: (1, 4)(2, -6)
timama [110]

Answer:

-10

Step-by-step explanation:

First use this equation: (y2 - y1) / (x2 -x1)

The y intercept is 14 so the slope is -10.

Please help with these 3 questions about simplifying square roots...
AfilCa [17]

Answer:

#2:

To get rid of a radical we multiply the radical by itself, so we multiply \frac{3}{\sqrt{2}} by \frac{\sqrt{2}}{\sqrt{2}}

to get \frac{3\sqrt{2}}{2}.

#3:

\sqrt\frac{2}{5} is the same as \frac{\sqrt{2}}{\sqrt{5}} so we multiply by \frac{\sqrt{5}}{\sqrt{5}} so we get \frac{\sqrt{10}}{5}.

#4:

We combine like terms to get  -2\sqrt{2} + 4\sqrt{3}

Hope this helps!

Jivesh is analyzing the flight of a few of his model rockets with various equations. In each equation, h is
balandron [24]

Answer:

1.22 s

Step-by-step explanation:

h = -810t² + 1980t

This is the equation of a parabola.

We must solve the equation to find the maximum height (h).

The coefficient of x² is negative, so the parabola opens downward, and the vertex is a maximum.

One way to solve this problem is to convert the equation to the vertex form.

We do that by completing the square.

Calculation:

h = -810t² + 1980t

Divide both sides by -810 to make the coefficient of  t² equal to 1.

(-1/810)h = t² - (22/9)t

Square half the coefficient of t

(-11/9)² = 121/81

Add and subtract it on the right-hand side

(-1/810)h = t² - (22/9)t  + 121/81 - 121/81  

Write the first three terms as the square of a binomial

(-1/810)h = (t - ¹¹/₉)² -121/81

Multiply both sides by -810

h = -810(t - ¹¹/₉)² + 1210

You have converted your equation to the vertex form of a parabola:

y = a(t - h)² + k = 0,

where (h, k) is the vertex.

h = ¹¹/₉ and k = 1210, so the vertex is at (¹¹/₉, 2100).

The maximum height of the rocket is 2100 cm.

After ¹¹/₉ s ≈ 1.22 s, the rocket will have reached a height of 1210 cm.

The graph below shows the rocket reaching 1210 cm at 1.22 s.

There were 150 females surveyed, evenly divided for all levels of expertise. there were 450 males surveyed. there were 80 expert
dlinn [17]

The values which would help complete the table according to the complete part of the task content are as evaluated.

<h3>What value would help complete the table?</h3>

First, the total number of average players can be evaluated by summing up the total number of players vertically as follows;

180 + average + 80 = 600

The number of average players is therefore; 600-180-80 = 340 average players.

Also, the number of female expert players can be evaluated vertically as;

50 + 50 + female expert = 150

Female expert = 150-50-50 = 50 female experts.

The number of male novice players can be evaluated horizontally as;

Male novice + 50 = 180

Male novice = 180 - 50 = 130.

The number of average male players is therefore easily evaluated vertically as;

130 + male average + 30 = 600

male average = 600-130-30 = 440.

Remarks: The table which is required to be completed is that which is in the attached image.
