A taxi company charges $1.00 for the first mile (or part of a mile) and 20 cents for each succeeding tenth of a mile (or part).
meriva

Step-by-step explanation:

solving functions separately.

1st:  from given data taxi charges $1.00 for the first mile.so it is first rule of function.

y_{1} =1 , 0

2nd: the company charge $0.20 per tenth of a mile.so 2nd rule of the function will  be

y_{2} =1+0.2.10(x-1)

simplifying

y_{2} =1+2(x-1)

y_{2} =x+2x-2

y_{2} =x ,  1

piece wise function is f(x)={2 ,  0<x<1

                                              {x ,  1<x<2

the graph of the function is given below

Factoring , <br> a² +4a - 5
givi [52]

the factors of the term a^2+4a-5 are (a-1)(a+5)

Step-by-step explanation:

We need to find factors of the term: a^2+4a-5

For finding factors:

We need to break the middle term such that their product is equal to product of first and last term and their sum is equal to middle term

Breaking the middle term and finding factors:

a^2+4a-5

=a^2+5a-a-5

=a(a+5)-1(a+5)

=(a-1)(a+5)

So, the factors of the term a^2+4a-5 are (a-1)(a+5)

Mon wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need…
nata0808 [166]
Whatever% of anything, is just (whatever/100) * anything.

the syrup is going to be 5lbs total, that includes the sugar in it as well as the water mix.

keeping in mind that the syrup will be a 1.5% syrup, namely 1.5% of it will be sugar, the rest just water then, how much is 1.5% of 5?

well, is just(1.5/100) * 5 or 0.075, namely lbs.

so, 0.075 lbs will be sugar and the rest water, the rest will be 5 - 0.075, or 4.925 lbs.
