What is the solution of this equation? -1/2n2+18=0
SashulF [63]

Answer:

n=-6\text{ or } n=6

Step-by-step explanation:

So we have the equation:

-\frac{1}{2}n^2+18=0

Subtract 18 from both sides. The left cancels:

-\frac{1}{2}n^2=-18

Multiply both sides by -2. The left cancels again:

n^2=36

Take the square root of both sides:

n=\pm\sqrt{36}

Since we're taking the square root, we need to use plus-minus.

Evaluate:

n=\pm 6

So, the solutions are -6 or 6.

What could be the ordered pairs representing vertices C and D of quadrilateral abcd so that the new fire department is congruent
ohaa [14]
Given that <span>a city grid of Anytown, USA is shown on the grid below. The fire department is represented by quadrilateral RSTU. Another fire department is opening in a different part of the city to maximize fire protection. The size of the new department's property must be congruent to the older department. Vertices A and B are plotted on the grid to represent two vertices of the new fire department quadrilateral ABCD.

Map of Anytown; the line y equals 7 is Main Road; the line y equals 3 is Rose Lane; the line y equals negative 1 is Crystal Avenue; the line x equals negative 4 is Brick Street; the diagonal line is Dogwood Drive; Old Fire Department forms quadrilateral with ordered pairs R at negative 4, 7, S at negative 1, 7; T at negative 1, 3; U at negative 4, 3; A is at 4, negative 1 and B is at 1, negative 1

Recall that t</span><span>wo shapes are said to be congruent if the lengths of the sides and the angles are the same.

For quadrilateral RSTU to be congruent to quadrilateral ABCD, then RS = AB, RU = AD, ST = BC and TU = CD

Also, the figure ABCD is a result of a rigid body translation of the figure RSTU.

Given that R is at point (-4, 7) and A is at point (4, -1), also given that S is at point (-1, 7) and B is at point (1, -1).

It can be seen that points AB is a result of refrecting points RS across the y-axis and then shifting the resulting points down by 8 units.

Thus, given point T as (-1, 3) and point U as (-4, 3), refrection of points T and U across the y-axis will result in points (1, 3) and (4, 3), then shifting the resulting points down by 8 units will result to points (1, -5) and (4, -5)

Therefore, the ordered pairs representing vertices C and D of quadrilateral ABCD so that the new fire department is congruent to the old fire department are C(1, -5) and D(4, -5).</span>

Is time a function of distance?
lukranit [14]

Answer: Distance traveled divided by rate provides the rate of change in position in time. For example, if Cole traveled 225 km at 45 km per hour and traveled 45/225 = 5 hours, then the rate of change in position was 30/5 = 20 minutes.

If the cost of 819.73 for full cover insurance for a female and a male is 1192.64 what is the percentage?
irinina [24]

Answer:

68.7%

Step-by-step explanation:

If the cost of 819.73 for full cover insurance for a female and a male is 1192.64 what is the percentage?

The Percentage is calculated as:

819.73/1192.64 × 100

= 0.68732392004293 × 100

= 68.732392004 %

Approximately = 68.7%

Therefore, the percentage is 68.7%
