What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The procedure of changing the basis of a number is known as number conversion. A binary number is made up of only two numbers: 1 and 0. A decimal number is made up of ten digits ranging from 0 to 9.
The values obtained from the table the decimal and the percentage form are solved as;

[tex]a_n = a_1r^{n-1}\ \ \ \ \ S_n = a_1(\dfrac{1-r^n}{1-r})[/tex]
Here we need to calculate the first term second term and common ratio to calculate the sum of the series.
a₁ = -2.(6¹⁻¹) = -2
a₂ = -2.( 6²⁻¹) = -2 (6) =-12
Common ratio:-
[tex]a_n = a_1r^{n-1}[/tex]
[tex]-12 = -2r^{2-1}[/tex]
r = 6
Put all the values in the sum formula:-

[tex]S_n = -2(\dfrac{279935}{5})=-2\times 55987[/tex]

Gcf of 24x^5 - 56x^3 + 16x
Answers
Answer:
8x
Step-by-step explanation:
Greatest common factor is the factor of 24, 56 and 16. Since 16x only has the power of 1, then then the answer should be on power of 1.
Answer:
Given the 24x⁵ - 56x³ + 16x contains numbers and variables, there are two steps to finding the GCF. Find the GCF for the numeric part, then find the GCF for the variable part.
Steps to find the LCD of 24x⁵ - 56x³ + 16x
Find the LCD for the numerical part 24, - 56, 16x Find the LCD of the variable part x⁵, x³, x¹.Multiply the values with each otherFind the common factors of the numerical part: 24, −56, 16
The factors for 24 are −24,−12,−8,−6,−4,−3,−2,−1,1,2,3,4,6,8,12,24.
The factors for −56 are−56,−28,−14,−8,−7,−4,−2,−1,1,1,2,2,4,4,7,7,8,8,14,14,28,28,56,56.
The factors for 16 are −16,−8,−4,−2,−1,1,2,4,8,16.
List all the factors 24,−56,16 to find the common factors.
24:−24,−12,−8,−6,−4,−3,−2,−1,1,2,3,4,6,8,12,24−56:−56,−28,−14,−8,-7,−4,−2,−1,1,1,2,2,4,4,7,7,8,8,14,14,28,28,56,5616:−16,−8,−4,−2,−1,1,1,4,8,16The common factors for 24,−56,16 are −8,−4,−2,−1.−8,−4,−2,−1
The GCF of the numerical part is 8.
[tex]\bf{GCF_{Numerical}=8 }[/tex]
Then find the common factors for the variable part:
x⁵, x³, x
The factors for x⁵ are:
x · x · x · x · x
The factors for x³ are:
x · x · x
The factors for x¹ are:
x
List all the factors x⁵, x³, x¹ to find the common factors.
x⁵ = x · x · x · x · x
x³ = x · x · x
x¹ = x
The common factor of the variables x⁵, x³, x¹ is x.
The LCD of the variable part is x.
[tex]\bf{GCF_{Numerical}=x }[/tex]
Multiply the LCD of the numerical part 8 and the GCF of the variable part x.

The faster you go, the faster you get home (theoretically anyway) and vice versa. So if your speed is doubled, it'll take half the time to get home. But if your speed gets halved, it'll also take double the time to get home.
So, if at 60 mph it takes 1 hour to get home, then if your speed is divided by four to 15 mph, you need to multiply the time by the same number and thus the answer is 4.

What is a vector?The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
A Ferris wheel with a diameter of 214 feet was built in a city.
The top of the wheel stands 223 feet above the ground.
Then the radius will be
r = 214 / 2
r = 107 feet
The distance between the ground and bottom of the Ferris wheel will be
d = 223 – 214
d = 9 feet
Then the height will be given as
h = r(1 – cos θ) + h
h = 107(1 – cos θ) + 9
At θ = 150°, then the height will be
h = 107(1 – cos 150°) + 9
h = 208.66 feet
At θ = 240°, then the height will be
h = 107(1 – cos 240°) + 9
h = 169.5 feet
At θ = 315°, then the height will be
h = 107(1 – cos 315°) + 9
