Answer:
an = 56-8(n-1)
Step-by-step explanation:
This is an arithmetic sequence
The common difference is 48 - 56 =-8
a1 = 56
an = a1+d(n-1)
an = 56-8(n-1)
Multiple and add
Step-by-step explanation:
For all of them you multiple 1 and add the inherent that's what area and perimter means
Answer:
c) 5
Step-by-step explanation:
In this question you are being asked to find the hypotenuse of the triangle
the triangle has one side that is 3 and the other is 4
use Pythagoras to find the missing side (a^2+b^2=c^2)
3^2+4^2=c^2
simplify the exponents
9+16=c^2
combine like terms/adding
25=c^2
take the square root
5=c
the length of the hypotenuse is 5
Answer:
d = 5t + 20
Step-by-step explanation:
d represents the distance and t represents the time, in hours
Let he equation which model this situation ⇒ d = a t + b
Where a and b are constant.
Let the gas station is the starting point
So, at gas station t = 0 , d = 20
∴ 20 = 0 * a + b ⇒ b = 20
When he reaches home 2 hours later notes that he has traveled 30 miles.
and with substituting with b = 20
∴ 30 = 2 * a + 20
2a = 30 - 20 = 10 ⇒ a = 10/2 = 5
∴ d = 5t + 20
The equations that can be used to model this situation <u>d = 5t + 20</u>
Answer:
GCF of 32 and 80 is 16
Step-by-step explanation:
factors of 32 = 1, 2, 4, 8, 16, 32
factors of 80 = 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
