Answer:
1.D
2.B
Step-by-step explanation:
question 1
-2(2)²+1/3(2)
-7/6
question 2
(-4x-2)(2x)
-8x²-4x
Answer: A) y = 3x + 2
Step-by-Step Explanation:
Let ‘x’ be the number of months
Let ‘y’ be the total no. of books he read
Given:
He read 2 books before joining (+2)
He plans to read 3 books per month (3x)
Equation:
= Total no. of books = 3 multiplied by the no. of months + 2 books he had read
=> y = 3x + 2
Volume of twin sized mattress =
39* 8.75* 75 = 25593.35 cubic inch
Volume of queen sized mattress =
60* 8.75* 80 = 42000 cubic inch
To fill 25593.35 cubic inch it takes 4 minutes
To fill 1 cubic inch it will take = 
minutes
So to fill 42000 cubic inch it will take = 
= 6.56 minutes.
a(1) = -4(1)-3 = -4-3 = -7
a(2) = -4(2)-3 = -8-3 = -11
a(3) = -4(3)-3 = -12-3 = -15
a(4) = -4(4)-3 = -16-3 = -19
a(5) = -4(5)-3 = -20-3 = -23
So, sequence would be -7,-11,-15,-19,-23
