What is the 1st term when -5z^2+7z^4+11z-8z^3 is arranges in descending order

The first term is

Step-by-step explanation:

1. To rewrite the given polynomial in descending order, you must see the exponent of each variable of the terms. Then, you must arrange the terms from bigger to smaller.

2. Keeping this on mind, you have:

3. As you can see, the first term is:

The first term in the descending order of the given expression is .

Step-by-step explanation:

We are giving the following expression and we are to arrange it in descending order and tell its which term comes first:

Rearranging the given expression in descending order, starting with the highest power, we get:

Therefore, the first term we get is .

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
