Answer:

Step-by-step explanation:

x = 4 it's a vertical line.

Perpendicular line to a vertical line is a horizontal line.

A horizontal line has equation y = a.

A horizontal line passes through the point (3, 5) → x = 3 and y = 5.

Therefore the equation is y = 5

Is this right and I need help getting the decimal estimate

Bumek [7]

The answer of 12 to 13 is almost correct - you only forgot the - signs

As for the decimal estimate, take the square root of 12 (144) and the square root of 13(169) and because 150 is closer to 144 than 169 we can guess that the decimal is about -12.2

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

Gnesinka [82]

Answer:

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.

HELP !!!! A rental car company charges $61 per day to rent a car and $0.12 for every mile driven. Nathan wants to rent a car, kn

Alla [95]

Answer:

2 days

Step-by-step explanation:

he plans to drive 400 miles, so the cost of his miles will 400*0.12=48

his total budget is 170, so subtract 48 from that

170-48=122

the rental company charges 61 per day and he has 122 after subtracting the cost of his miles, so he will have 122/61 days to drive 400 miles

122/61=2

In a town survey, residents were asked whether they would approve of a tax increase to build a new library. Four-sevenths of the

swat32

Answer: (A) The fraction of residents opposed to the project was three-sevenths (3/7)

(B) The total number of residents is 2,128.

Step-by-step explanation: If the number of residents in support of the building project is expressed as a fraction of the total number, then the total number can be expressed as 1. That means we should have two fractions, those in support and those not in support and their addition should be equal to 1.

Hence if the total is 1 and 4/7 are in support, the fraction of those opposed (let that be y) can be calculated as

y = 1 - 4/7

y = 7/7 - 4/7

y = (7 - 4)/7

y = 3/7

Also, the number of residents not in support is 912 (which is 3/7 of the total). That means 912 is three out of seven of f the total population. In other words,

3/7 = 912/x

(Where x is the total population)

By cross multiplication we now have

3x = 912 x 7

x = 6384/3

x = 2128

Therefore the total population of residents is 2,128.
