Step-by-step explanation:
Suppose scientists compared the wind speeds and barometric pressure readings of two severe storms over the Atlantic Ocean. For one of the storms, the barometric pressure was 1,000 mb (millibars), and the maximum wind speed was 100 kmh (kilometers per hour). The second had a barometric pressure of 960 mb and maximum wind speeds of 180 kmh. (a) Develop a rule that you could use to predict the wind speed given any barometric pressure.
Answer:
So i found the teacher notes after hours of looking here are the exact answers so i would recommend changing the wording.
Part A: Ordered pairs in the form (mb, kmh): (1,000, 100) and (960,180) Let X be the barometric pressure and Y be the wind speed.
Slope= (180-100)
---------------- = -2
(960-1000)
Formula: y=-2(x-1000)+100
Part B: y=-2(980-1000)+100=140
140 kmh is reasonable. Because 980 mb is halfway between 960 mb and 1000 mb, we should expect a wind speed halfway between 180 kmh and 100 kmh.
Part C: The wind speed intercept is (0,2100) [or (2100,0) if written that way.] This means that when brometric pressure is 0 mb, then the wind speed would be 2100 kmh. However in the context of real weather, this is an impossible situation.
Part D: The slope means that every decrease of 2 kmh in wind speed corresponds to a 1 mb increase in barometric pressure.

Find x AND the length of each side if ABC is an isosceles triangle with AB = BC . (Answers Rouen to the nearest tenth if needed)
Answer:
x = 7
AB = 7
BC = 7
Step-by-step explanation:
AB = BC cuz it's an isosceles triangle
In the given isosceles triangle x is 7 units and AB ≅ BC is also of 7 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
As the triangle has two equal sides we can equate two expressions to find x.
∴ 2x - 7 = 4x - 21.
- 2x = - 14.
2x = 14.
x = 7.
AB = 2(7) - 7.
AB = 14 - 7.
AB = 7.
BC will also be of 7 units as AB ≅ BC.

Use the coefficient of variation to determine

on
Data Set 1: 2 = 12 and s = = 7
Data Set 2: 2
0.12 and s
= 0.3.
Data Set 1 CV ~
% (Round to the
nearest percent)
Data Set 2 CV =
%
Answer:
Dataset 2
Step-by-step explanation:
The Coefficient of variation is the ratio of the standard deviation and the population mean.
Data Set 1: 2 = 12 and s = = 7
Data Set 2: 2
0.12 and s
= 0.3.
Coefficient of variation = (standard deviation / mean) * 100%
Dataset 1:
Standard deviation = 7 ; mean = 12
Coefficient of variation = (7 / 12 ) * 100% = 0.5833 = 58%
Dataset 2:
Standard deviation = 0.3 ; mean = 0.12
Coefficient of variation = (0.3 / 0.12) * 100% = 2.5 * 100% = 250
Hence dataset 2 varies the most with a greater value of variation Coefficient.

We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
We can use the fact that in a triangle, the side opposite the smallest angle is the shortest side.
So we need to determine which angle is the smallest.
Now,
In ΔQRS,
m∠Q = 63º, m∠R = 70°, and m∠S= 47°
Now,
m∠S= 47° is the smallest.
So,
QR is the side opposite to m∠S.
Thus,
QR is the shortest side.

Answer:
d = [tex]\pi[/tex]
e = [tex]-\sqrt{8}[/tex]
f = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
D is equal to pi because pi is 3.1415... Therefore we need a point that is a little more than -3 and that is point d.
[tex]-\sqrt{8}[/tex] is roughly equal to -2.8 because 3 * 3 = 9 so that is too much, and 2 * 2 = 4 is too little so it has to be between -2 and -3. Therefore the point is e.
For 3/2 it has to be less than 2 because 2 cannot go into 3 more than once. The point would then be point f.

Answer:
15
Step-by-step explanation:
First we need to find the length of BC and for that we gonna use Pysagoras theorem
10^2 + (2√11)^2 = |BC|^2
√144 = |BC|^2
12 = BC Now we will use this to find the value of x
x^2 = 12^2 + 9^2
x^2 = 144 + 81
x^2 = 225
√x^2 = √225
x = 15
Answer:
The value of x is 15 cm.
Step-by-step explanation:
There are two triangles in the diagram that share a common side.
The triangles are:
ABC and BDC
First we have to find the third side of BDC so that we can use it to find the value of x.
The triangle is a right angled triangle so Pythagoras theorem can be used to find the third side.
In the triangle
[tex]Base = BD =10cm\\Hypotenuse = BC = ?\\Perpendicular = CD = 2\sqrt{11}cm[/tex]
Pythagoras theorem is given as:
[tex](Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\BC^2 = BD^2 + CD^2\\BC^2 = (10)^2 + (2\sqrt{11})^2\\BC^2 = 100+(2^2 * 11)\\BC^2 = 100+(4*11)\\BC^2 = 100+44\\BC^2 = 144\\\sqrt{BC^2} = \sqrt{144}\\BC = 12cm[/tex]
Now for triangle ABC
[tex]Base = BC = 12 cm\\Perpendicular = AB = 9 cm\\Hypotenuse = AC = x\\[/tex]
Using Pythagoras theorem
[tex]AC^2 = BC^2+AB^2\\x^2 = (12)^2 + (9)^2\\x^2 = 144+81\\x^2 = 225\\\sqrt{x^2} = \sqrt{225}\\x = 15cm[/tex]
Hence,
The value of x is 15 cm.

b) 16
c) 32
the answer is :
8^20 (eight to the twentieth power)
[tex]2^{60}[/tex] is equivalent to [tex]16^{15}[/tex].
We can rewrite the expression by means of the following power property, that is to say:
[tex]a^{b\cdot c} = (a^{b})^c[/tex], [tex]a, b, c\in \mathbb{N}[/tex] (1)
Where [tex]a[/tex] and [tex]a^{b}[/tex] are bases.
If we know that [tex]a = 2[/tex] and [tex]b\cdot c = 60[/tex], then the equivalent expression is:
[tex]2^{60} = 2^{4\cdot 15} = (2^{4})^{15} = 16^{15}[/tex]
Hence, [tex]2^{60}[/tex] is equivalent to [tex]16^{15}[/tex].
