Answer:
i) Sally' s grocery bill = c -
c = 0.95c
Therefore the correct option is B.)
ii) Therefore the expression which represents the expected population
next year is given by :
= p +
p = 1.075p
Therefore the correct option is B.)
Step-by-step explanation:
Sally has a discount card that reduces the price of her grocery bill in a certain grocery store by 5%.
Let c represent the cost of Sally's groceries.
therefore the expression which represents Sally's grocery bill is given by :
Sally' s grocery bill = c -
c = 0.95c
Therefore the correct option is B.)
The population of a city is expected to increase by 7.5% next year If p represents the current population, which expression represents the expected population next year?
Let p = current population of a city.
Therefore the expression which represents the expected population next year is given by :
= p +
p = 1.075p
Therefore the correct option is B.)
Answer:
Yes, Sally has enough money to buy 28 cans of soda.
Step-by-step explanation:
Yes, because £10 = 1000p
1000p / 28p = 35 cans
35 cans < 28 cans
So Sally has enough money for 28 cans.
Do you mean the slope of the line or the y-intercept
(2002-2001)/(18.75-17.60)= 0.869 =slope
y=mx + b -> 2001= 0.869 (17.60) +b -> b= 1985.7= y-intercept

Answer:
arg (w)=π/4 and |w|=√2
Step-by-step explanation:
If z= x+iy is a complex number, then |z| is given by √ ( x²+y² ).
And the argument (z) is given by Ф = tan⁻¹ ( y/x ) where -π < x < π.
Now, in our case w= 1+i i.e. x=1 and y=1.
Therefore, arg (w) = tan⁻¹ (1/1) = π/4 and |w|=√ ( 1²+1² ) = √2 (Answer)
