Answer:

  see attachments

Step-by-step explanation:

The side lengths are found using the distance formula.

  d = √((x2-x1)^2 +(y2-y1)^2)

For example, the length of RS in the first triangle is ...

  d = √((4-(-1))^2 +(4-(-3))^2) = √(25 +49) = √74 ≈ 8.602

This same computation is used for all of the sides of the triangles. When the same tedious computation is repeated over and over, I like to use a spreadsheet to do it. In the attached spreadsheet the two points used are the one on the same line as the distance, and the one on the line below. Side lengths are shown in the attachment to 3 decimal places.

__

In order to classify the triangle as acute, right, or obtuse, we can compare the side lengths to those of a right triangle. For the purposes of computation in a spreadsheet, it is convenient to compute the middle length side of a right triangle that has the same longest and shortest sides as the triangle we have.

If the computed side is longer than the actual middle side, then the triangle we have is obtuse. If it is shorter, the triangle we have is acute. If it is exactly the same, then the triangle we have is a right triangle.

In every case here, the computed middle side is shorter than the actual middle-length side, so all of the triangles are acute triangles. (The one of problem 39 is isosceles, since two sides are the same length. The others are scalene.)

Answer:

4.76%

Step-by-step explanation:

A jar will hold 252 grams of powder

The label shows that its contains 240 grams

Therefore the percent error can be calculated as follows

= 240-252/252 × 100

= -12/252 × 100

= 0.0476 × 100

= 4.76%

Hence the percent error is 4.76%

Answer:

AB  = 8

Step-by-step explanation:

Using the similarity theorem of a triangle;

AC/AD = AB/AE

AC = AB + BC and AD = AE + ED

AB + BC/AE + ED = AB/AE

Substitute the given values

AB+12/15 = AB/6

Cross multiply

6(AB+12) = 15AB

6AB + 72 = 15AB

15AB - 6AB = 72

9AB = 72

AB = 72/9

AB = 8

Step-by-step explanation:

From the question :

Duration, time, t = 3 minutes, 27 seconds = (3 * 60) + 27 = 207 seconds

Average speed = 15 km/h = (15*1000) /3600 = 4.16666 m/s

Let distance = x

Recall:

Speed = distance / time

Distance = speed * time

x ≤ (speed * time)

x ≤ (4.16666 * 207)

x ≤ 862.5 m

x ≤ (862.5 / 1000) km

x ≤ 0.862.5 km

Answer:

r = 10

y = 11

Step-by-step explanation:

4y = 40 + 4

4(r + 1) = 40 + 4

4(r) + 4(1) = 40 + 4

4r + 4 = 40 + 4

4r + 4 = 44

4r + 4 - 4 = 44 - 4

4r = 40

4r ÷ 4 = 40 ÷ 4

r = 10

-----------------------------------------

y = r + 1

y = (10) + 1

y = 11

-----------------------------------------

4y = 40 + 4

4(11) = 40 + 4

4(11) = 44

have a nice day!!

I will do it in a way that can solve all these kinds of problem.

Of course, you can just substitute every possible answer in and see which one has the highest y value.

BUT I'm going to do this question by completing the square.

First organize the equation by decreasing degrees.

y=-16t^2+32t

Now factor out a -16 to make the x variable have no coefficient.

y=-16(t^2-2t)

Now complete the square.

y=-16(t-1)^2+16

By this if you graph it its the parent graph y=x^2, its a reflection over x axis by the negative sign at the beginning, then a vertical stretch by 16, and then go to the right by 1 then up by 16. This meant that the vertex is (0,0) go right 1 and up 16.

The vertex or the highest point of the graph is point (1,16) This also meant that its after 1 second at 16 feet height. The answer is B.

Answer:

The true statement of the area of the piece of land is;

(C) It is between 0.0007 and 0.007 square mile

Step-by-step explanation:

Using scientific notation, we have the value of a measurement presented as follows;

c × 10ⁿ = ce±n

Where;

c = The coefficient number, less than 10

en = 1 × 10⁺ⁿ

e-n = 1 × 10⁻ⁿ

Therefore, the given number, 7.4 e - 4, can be expressed as follows;

7.4 e - 4 = 7.4 × 10⁻⁴ = 0.00074

0.00074 ≈ 0.0007 and we have;

0.0007 < 0.00074 < 0.007

The correct option is therefore that it is between 0.0007 and 0.007 square mile

The statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074

The standard form for writing scientific notation is given as A * 10^n

Writing this as a standard value will give:

Hence the statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074

At value of x=4

A pair of numbers that describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines  are called coordinates. General form of coordinate is (x, y)

From the graph we can see , coordinates of that point where both the lines are intersecting is (4, -3)

Because x coordinate is = 4

and y coordinate is = -3
