Answer:
7/3
Step-by-step explanation:
integral of equation is x^3/3-6x^2/2+5x/1
the answer will be
7^3/3-3*7^2+5*7-0= 343/3-147+35= 7/3
Answer:
Option A
Step-by-step explanation:
Weight of an apple = twice of the weight of a lemon
Weight of an apple = 2(weight of a lemon)
x = 2y ------(1)
x = weight of an apple
y = weight of a lemon
Number of apples in a box = 16
Weight of the apple box (A) = 16x
Number of lemons in another box = 24
Weight of the lemon box (B) = 24y
Therefore, 

[From equation (1)]

Answer:

Step-by-step explanation:
<u>Step 1 :</u>-
<u>Perpendicular condition :-</u>
<u>Step 1:-</u>
Two non-vertical lines are perpendicular to each other if and only if their slopes are negative reciprocals of each other.


<u>Step 2:-</u>
The given points are (-8,k) and (-4,-8)

finding slope of the first line is 
using formula 
= 
finding slope of the second line is 
using formula 
= 
<u>Step 3:</u>-
using perpendicular condition
The two lines are perpendicular and their slopes are


simplification,we get solution is






<u>Final answer is </u>
