Answer:

Option A

Step-by-step explanation:

Let's find common difference

$\\ \sf\longmapsto \dfrac{7}{12}-\dfrac{5}{12}$

$\\ \sf\longmapsto \dfrac{7-5}{12}$

$\\ \sf\longmapsto \dfrac{2}{12}$

$\\ \sf\longmapsto \dfrac{1}{6}$

Hence verified

The son of three consecutive even integers is 126. let X represent the first integer, X +2 represents the second integer, and X

navik [9.2K]

X+X+2+X+4 = 3X + 6 = 126

3X = 126-6 = 120

X = 120/3 = 40

X = 40
X+2 = 42
X+4 = 44

A carpenter has a board that is 8 feet long. He cuts off two pieces. One piece is 3 1/2 feet long and the other is 2 1/3 feet lo

Aneli [31]

Add 3 1/2 and 2 1/3,

Firstly, find the common denominator. It is is 6

3 3/6 + 2 2/6

this gets you 5 5/6.

Take this away from 8:

8 - 5 5/6 = 2 1/6

So 2 1/6 of the board is left over.

Find the Range and Domain of the Binary relations

sukhopar [10]

Answer:

A = {3,5,6}

B = {1,3}

A x B = {(3,1),(3,3),(5,1),(5,3),(6,1),(6,3)}

Domain of A x B = (The x figures in ascending order)

=> {3,5,6} (Figures repeating more than once must be written only 1 time)

Range of A x B = (The y figures in ascending order)

=> {1,3}

B x A = {(1,3),(3,3),(1,5),(3,5),(1,6),(3,6)}

Domain of B x A = {1,3}

Range of A x B = {3,5,6}

A certain forest covers an area of 4600km. Suppose that each year this area decreases by 7.75%. What will the area be after 13 y

wolverine [178]

Answer:

$1679.60\ km^2$

Step-by-step explanation:

-We can use the exponential decay function to estimate the size after 13 years:

$P_t=P_oe^{-rt}$

Where:

$P_t$ is the size after t years, t is the time, r is the rate of decay and $P_o$ the original size.

#We substitute and calculate as:

$P_t=P_oe^{-rt}\\\\=4600e^{-13\times 0.0775}\\\\=1679.60$

Hence, the forest covers $1679.60\ km^2$ after 13 years.
