Answer:
SD=10
Step-by-step explanation:
S=the intersection of the medians
SD=JD/3
SD=30/3
SD=10
Answer:
603
Step-by-step explanation:
The rate of change is found by
rate of change = f(b) -f(a)
------------
b-a
We need to find the rate of change for the interval 7,9 and 4,6
We know b= 9 and a = 7
f(9) -f(7)
------------
9-7
3878-1852

We know b= 6 and a = 4
f(6) -f(4)

Answer:
90.16
Step-by-step explanation:
91.13 - 0.97=90.16
We will use PEMDAS rule to simplify the given expression.
PEMDAS rule is given by:
P
-Parentheses first
E
-Exponents (ie Powers and Square Roots, etc.)
MD-Multiplication and Division (left-to-right)
AS
-Addition and Subtraction (left-to-right)

Step 1: P-parenthesis first.
(3-9) is -6
√16 -1 = 4-1 =3
So new expression becomes : 
Step 2:
Multiplying (-3)*(-6)*2
We get +36
So new expression becomes : 25 +36
Step 3: Addition
Adding 25 and 36 we get 61
So final answer is 61 .
Use basic multiplication: 7x (8) = 56x
or 7(8) x = 56x
