Answer:
[tex]-\frac{1}{5}[/tex]
Step-by-step explanation:
Notice that the equation y = 5x - 16 is in slope-intercept form, or [tex]y = mx + b[/tex] format. Whenever an equation is in slope-intercept form, the number in place of the [tex]m[/tex], or the coefficient of the x-term, represents the slope of that line. So, the slope of the given line is 5.
Slopes that are perpendicular to each other are opposite reciprocals. So, we need to find the opposite reciprocal of 5. To do that, write it as a fraction, making it [tex]\frac{5}{1}[/tex]. Then, switch the sign and flip the numerator and denominator. This means that the opposite reciprocal of 5 is [tex]-\frac{1}{5}[/tex], so [tex]-\frac{1}{5}[/tex] is the perpendicular slope.
Which equation is written in slope intercept form?
a) 2x + 8 = 4y
b) 2x + 7y = 1
c) y = - 4x + 11
d) x = x +4

If 20% of a number is 160 then the original number is
Answer:
800
Step-by-step explanation:
160 * 100% / 20% = 800
If 20% of a number is 160 then the original number is 800.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that 20% of number is 160
We need to find the original number.
Let the original number be x
Convert 20% to decimal value by dividing 20 with 100
20/100=0.2
Now multiply 0.2 with x which is equal to 160
0.2x=160
Divide both sides by 0.2
x=800
Hence, If 20% of a number is 160 then the original number is 800.

What is the greatest common factor of 45x^3, 24x^2, and 16x?
Answer:
[tex]\huge\boxed{\sf GCF = x}[/tex]
Step-by-step explanation:
Firstly we'll factorize the terms:
45x³ = 3 * 3 * 5 * x * x * x
24x² = 2 * 2 * 2 * 3 * x * x
16x = 2 * 2 * 2 * 2 * x
The factor which is common in all three terms is:
= x
Hence GCF = x

Giovanni is visiting his grandmother who lives in an apartment building on the 25th floor. Giovanni enters the elevator in the lobby, which is the first floor of the building. The elevator stops on the 16th floor. What percentage of 25 floors does Giovanni have left to reach his grandmothers floor?
Answer:
the percentage is 36%
Step-by-step explanation:
The computation of the percentage of 25 floors does Giovanni have left to reach his grandmothers floor is shown below:
= (25 floor - 16 floor) ÷ (25 floor)
= 9 floor ÷ 25 floor
= 36%
Hence, the percentage is 36%

What is the distance between the points (5, 13) and (-8, -9) on a coordinate plane rounded to the nearest tenth unit?
Answer:
25.6
Step-by-step explanation:
Use the distance formula.
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\d = \sqrt{(-8 - 5)^2 + (-9-13)^2}\\d = \sqrt{(-13)^2 + (-22)^2}\\d = \sqrt{169 + 484}\\d = \sqrt{653}[/tex]
The distance between the points (5, 13) and (-8, -9) is 25.6 units after using the distance formula.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have two points (5, 13) and (-8, -9)
[tex]\rm d=\sqrt{(-8-5)^2+(-9-13)^2}[/tex]
d = √(169+484)
d = 25.55 units ≈ 25.6 units
Thus, the distance between the points (5, 13) and (-8, -9) is 25.6 units after using the distance formula.

The St. Petersburg paradox goes as follows. A fair coin is tossed repeatedly until it comes up heads. If the first heads appears on the nth toss, you win $2 n . First, show that the expected monetary value of this game is infinite (the paradox is that no one would actually pay a huge amount to play this game). Second, consider a possible resolution of the paradox: suppose your utility for money is given by a log 2 x b where x is the number of dollars you have. Suppose you start with 0 dollars, what is the expected utility of this game
Answer:
a) attached below
b) 2a + b
Step-by-step explanation:
a) show that the expected monetary value of this game is infinite
Given that the probability of getting first head on nth toss = $2^n
attached below is the prove
b) what is the expected utility of this game
using the Logarithm ; [tex]U(x) = a log_{2} n + b[/tex]
x = number of dollars you have

New York City is located about 40˚ north of the equator. If Earth's radius is about 4000 miles, approximately how many miles south would a plane need to fly from new York City to reach the equator?
Answer:
The answer is "2793 miles"
Step-by-step explanation:
In this firstly we convert degrees to radians, which can be defined as follows:
[tex]\to \theta =\frac{40^{\circ} \times \pi }{180^{\circ}}[/tex]
[tex]=\frac{ 2\pi }{9}[/tex]
Now calculating the distance:
[tex]=\frac{2\pi }{9} \times 4000\\\\= \frac{8000 \pi }{9}[/tex]
[tex]=\frac{8000\times 3.14 }{9}\\\\ = \frac{25120}{9}\\\\=2793 \ miles[/tex]

A bird sitting at the top of a tree looks down at an angle of 500 , at an earthworm on the ground. If the earthworm is 7m away from the base of the tree, determine the height of the tree to 1 decimal place.
Answer: 8.3 m
Step-by-step explanation:
Given
The angle of declination is [tex]50^{\circ}[/tex]
Earthworm is [tex]7\ m[/tex] away from the base of the tree
Suppose h is the height of the tree
from the figure, we can write
[tex]\Rightarrow \tan 50^{\circ}=\dfrac{h}{7}\\\\\Rightarrow h=7\tan 50^{\circ}=8.3\ m[/tex]
