Step-by-step explanation:

Equation of given line is:

$y = - \frac{1}{2} x + 5 \\ \\ equating \: it \: with \: y =m_1x + c \\ we \: find \: \\ m_1 = - \frac{1}{2} \\ let \: m_2 \: be \: the \: slope \: of \: required \: line \\ \\ \therefore \: m_1 \times m_2 = - 1( \because \: lines \: are \: \perp) \\ \\ \therefore \: - \frac{1}{2} \times m_2 = - 1\\ \\ \therefore \: m_2 = 2 \\$

Thus, the slope of required line is 2.

Find the first six terms of the sequence. a1=-7, an=2*an-1

AlladinOne [14]

The first term of the sequence is $a_{1} = -7$ .

The sequences is recursive, every next term of the sequence is obtained by multiplying the previous term by 2.

So, we can find the next 6 terms as shown below:

$a_{2} = 2*a_{1}=2(-7)=-14$
$a_{3} = 2(-14)=-28$
$a_{4} = 2(-28)=-56$
$a_{5} = 2(-56)=-112$
$a_{6} = 2(-112)=-224$
$a_{7} = 2(-224)=-448$

A light bulb consumes 1440 watt hours per day. How many watt hours does it consume in 5 days and 18 hours

Maurinko [17]

Answer:

8,280 watt hours

Step-by-step explanation:

1440/24 = 60 watt hours per hour

5*24=120 hours in 5 days

120+18=138

138*60=8,280 watt hours
