The line is parallel to y = 6/7 x - 5

The slope will be same .So equation of the line will be of the form:

$y = \frac{6}{7} x + k \\$

It passes through C(1,5)

$5 = \frac{6}{7} \times 1 + k \\ \\5 = \frac{6}{7} + k \\ \\ k = 5 - \frac{6}{7} \\ \\ k = \frac{7 \times 5 - 6}{7} = \frac{29}{7}$

$line : \red{y = \frac{6}{7} x + \frac{29}{7} } \\$

In an arithmetic sequence, the nth term an is given by the formula An=a1+(n−1)d, where a1

Gnesinka [82]

Answer:

88

Step-by-step explanation:

We are given that in arithmetic sequence , the nth term $a_n$ is given by the formula

$A_n=a_1+(n-1)d$

Where $a_1=first term$

d=Common difference

In an geometric sequence, the nth term is given by

$a_n=a_1r^{n-1}$

Where r= Common ratio

1,4,7,10,..

We have to find 30th term.

$a_1=1,a_2=4,a_3=7,a_4=10$

$d=a_2-a_1=4-1=3$

$d=a_3-a_2=7-4=3$

$d=a_4-a_3=10-7=3$

$r_1=\frac{a_2}{a_1}=\frac{4}{1}=4$

$r_2=\frac{a_3}{a_2}=\frac{7}{4}$

$r_1\neq r_2$

Therefore, given sequence is an arithmetic sequence because the difference between consecutive terms is constant.

Substitute n=30 , d=3 a=1 in the given formula of arithmetic sequence

Then, we get

$a_{30}=1+(30-1)(3)=1+29(3)=1+87=88$

Hence, the 30th term of sequence is 88.

The length of a rectangle is twice its width. if the area of the rectangle is 200 yd2 , find its perimeter.

Lorico [155]

Width: x
Length: 2x
Area=x(2x)=2x^2
2x^2=200
x^2=100
x=10 or -10(reject as x>0) [width cannot be less than 0, doesnt make sense]
Perimeter
=x+x+2x+2x
=6x
=6(10)
=60 yd
