Answer:

R-{-5}

Step-by-step explanation:

you get the vertex by making the denominator =0

ex.z+5=0 ,z=-5

then we see if the rational function has a constant beside it ex. 3÷z+5-3 ,but in this you Don't have one so its 0

so the vertex would be (-5,0)

the domain =R-{-5} , range=R-{0}

What is 4 1/3 × 2 3/5? express it in lowest terms

soldier1979 [14.2K]

We have,

$4\dfrac{1}{3}\cdot2\dfrac{3}{5}=\dfrac{13}{3}\cdot\dfrac{13}{5}=\dfrac{13\cdot13}{3\cdot5}=\dfrac{169}{15}=\boxed{11.2\bar{6}}$

To express periodic number calculated we use:

$x=11.2\bar{6}\\10x = 112.\bar{6}\\100x=1126.\bar{6}\\90x=100x-10x\Longrightarrow90x=1126.\bar6-112.\bar6\\90x=1014\\x=\dfrac{1014}{90}=\boxed{11\dfrac{24}{90}}$

Hope this helps.

Kamil is saving up to buy a model of Big Ben costing £30 when he visits London. So far he has saved €15.00. How much more money

Naddika [18.5K]

Answer:

€18.40 or £16.53.

Step-by-step explanation:

Kamil is saving up to buy a model of Big Ben costing £30 when he visits London.

He has saved €15.00.

First, we have to convert his savings to Pounds(£) and then, subtract that from the amount he needs.

€1 = £0.90

€15 = 15 * 0.9 = £13.47

So, Kamil has saved £13.47.

Therefore, the amount he has left to save is:

£30 - £13.47 = £16.53

To find this amount in Euros, we convert it to Euros:

£1 = €1.11

16.53 = 16.53 * 1.11 = €18.40

He has to save €18.40 or £16.53.

RSM PROBLEM NEED HELP!!!!!! In the figure, if PN = LN, NP ∥MQ, and QL

meriva

The value of x is 67°

<u>Step-by-step explanation:</u>

Given that

PN=LN

NP||MQ

QL bisects <PQM

therefore <PQL=<LQM

NP||MQ and NM is a transversal

<PNL+<LMQ=180°(angles on the same side of the transversal are supplementary)

<PNL+54=180°

<PNL=180-54=126°

Consider ΔPNL

since PN=NL,the triangle is isocelus

<NPL=<NLP=a

<NPL+<NLP+<PNL=180°

a+a+126=180°

2a+126=180

2a=180-126

=54°

a=54/2=27°

consider the point L

<NLP+<PLQ+<MLQ=180°

27+70+<MLQ=180

<MLQ=180-97=83°

consider ΔLQM

<LQM+<LMQ+LMQ=180

<LQM+83+54=180

<LQM=180-(83+54)=180-137=43°

<PQL=43°(since<PQL=<LQM)

considerΔPQL

x+70+<PQL=180°

x+70+43=180°

x+113=180

x=180-113

=67°

The value of x is 67°
