The incline of a roller coaster is 2 times as long as its elevation, and the horizontal length of the roller coaster is 11 m mor
Gelneren [198K]
Let 
x-------> t<span>he horizontal length of the roller coaster
y------> </span>the elevation of the roller coaster
c------> t<span>he incline of a roller coaster
</span>
we know that
applying the Pythagoras theorem
c²=x²+y²-----> equation 1
c=2y-----> equation 2
x=11+y----> equation 3

substitute equation 2 and equation 3 in equation 1
[2y]²=(11+y)²+y²
4y²=11²+22y+y²+y²
2y²-22y-121=0

using a graph tool-----> to resolve the second order equation
see the attached figure

the solution is 
y=15.026 m

c=2*y-----> c=2*15.026----> c=30.052 m

the answer is
30.05 m

3. Suppose you were collecting data about dogs. Give at least two examples of discrete and two examples of continuous data you m
Mashutka [201]

Answer:

The discrete data can be number of legs, number of teeth.

The continuous data can be the length of tail, and the height of dog.

Step-by-step explanation:

Consider the provided information.

The discrete data is a data whose value is obtained by counting and they can be described by an integer value.

So, the discrete data can be number of legs, number of teeth.

A continuous data is a variable whose value is obtained by measuring.

The continuous data can be the length of tail, and the height of dog.

What is the area of the shape?
ddd [48]
We can split the shape into a square of lengths, 12*12 and a triangle of lengths, 8*12. (This shape is not to scale BTW) The area of the square is 144, and the area of the right triangle is 48, so the answer is 192 square units squared.

Another way of doing this is using the trapezoid area formula, which is
(b1 + b2)/2 * h. So 32/2 * 12 = 16*12 = 192.

If the system of inequalities y&gt;= 2x + 1 and y &gt; 1/2x -1 is graphed in the xy-plane above, which quadrant contains no solu
kvv77 [185]

Answer:

View graph

Step-by-step explanation:

We have as a solution of the inequalities the shaded region in quadrant I, that is, there is no solution in quadrants II, III and IV

For the equation y ≥ 2x + 1 the region generated by the values ​​on the line and to the left is taken, and for the inequality y> 1 / 2x-1 the region generated by the values ​​on the curve and to the right is taken
