Answer:
there is a lot of solutions here is some guidance. so if there are more then 4 and less then 10 then every solution should equal 5, 6, 7,8, and 9. also it says the number of pencils is more then the number of pens so for example if it was to equal 9 i would put 5 + 4 . 5 is the number of pencils, 4 is the number of pens or i could put 6 + 3 so any numbers that equal to what i said; 5, 6, 7,8, and 9. good luck!
Step-by-step explanation:
I did it quickly on a calculator but if you multiply 250 and .7 you get 175, and then subtract 175 from 250 then you get $75, and 75 is your answer
Hope this helps!! :D
As the focus is at (0,5) it will be symmetrical about the y axis and will open upwards
General formula is x^2 = 4ay where a is the y coordinate of the focus
So its y = x^2/5*4
y = 1/20 x^2
Answer:
$5.25
Step-by-step explanation:
If the friend tripled the first purchase and subtracted twice the second purchase, he would have the cost of 3·8-2·5 = 14 notebooks. 7 notebooks would cost half that amount:
(3·$11 -2·11.25)/2 = $5.25 . . . . . cost of 7 notebooks
Initial salary = $50,000 .
Rate of raise = 5% each year.
Therefore, each next year salary would be 105% that is 1.05 times.
5% of 50,000 = 0.05 × 50000 = 2500.
Therefore raise is $2500 each year.
According to geometric sequence first term 50000 and common ratio 1.05.
Applying geometric sequence formula
1) 
2) In order to find salary in 5 years we need to plug n=5, we get
= 50000(1.21550625)
<h3>=$60775.3125.</h3>
3) In order to find the total salary in 10 years we need to apply sum of 10 terms formula of a geometric sequence.
Plugging n=10, a = 50000 and r= 1.05.
= 628894.62678.
<h3>Therefore , you will have earned $ 628894.62678 in total salary by the end of your 10th year.</h3>
