Answer:
x² - 10x + 2
Step-by-step explanation:
(x - 2)(2x + 3) = 2x² + 3x - 4x - 6
= 2x² - x - 6
(3x² - 11x - 4) - (2x² - x - 6) = x² - 10x + 2
Answer:
13.5
Step-by-step explanation:
Using sine rule
Tan25 = AC/AB = AC/29
AC = 29 × Tan 25 = 29 × 0.45 = 13.5229220865
Answer:
7+22i
Step-by-step explanation:
Since this is like a binomial, you have to apply the foil method
(-2+3i)(4-5i)=-8+10i+12i+15
(the 15 is the product of 3i*-5i)
Now, you combine like terms
-8+15=7
10i+12i=22i
so the expression in a+bi form is 7+22i
The formula is
A=p (1+r/k)^kt
A future value?
P present value 12000
R interest rate
T time
K compounding periods
The future value of 8 years in an account paying 5% compounded quarterly
A=12,000×(1+0.05÷4)^(4×8)
A=17,857.566103137 use it as a present value for the second period
at 6% compounded annually for an additional 6 years.
A=17,857.566103137×(1+0.06)^(6)
A=25,331.30....answer
Answer:
It's D I believe because y is the total cost . $2.50 is being added per pound of berries they pick which represents x. Then you add the $3 payed to enter the farm. Hopefully it's righttt :)
