2.5
Step-by-step explanation:
4x2.5=10
Answer:
Length of diagonal in the first top figure is 13 yd
Okay for this one, the formula of a diagonal in a cuboid is the root of sum of squares
length, breadth and height
so
D = root of 12^2 + 4^2 + 3^2
D = root of 144 + 16 + 9
D = root 169
D = 13yd
Length of diagonal in the bottom figure is 10.77 which is 10.8m
For this one, you have to find the diameter of base first
Since radius of the base is 5 diameter = 10
Since its a right angled triangle, Hypotenuse square = sum of sides square
Diagonal^2 = 10^2 + 4^2
D^2 = 100 + 16
D^2 = 116
D = root 116
D = 10.77
D = 10.8 m
6 - x = 2(x - 6)
the first step, following PEMDAS, is to distribute the 2 to the inside of your parentheses:
6 - x = 2x - 12 ... subtract 2x
6 - 3x = -12 ... subtract 6
-3x = -18 ... divide by -3
x = 6 is the answer

Step-by-step explanation:
Answer:
a_n = 2^(n - 1) 3^(3 - n)
Step-by-step explanation:
9,6,4,8/3,…
a1 = 3^2
a2 = 3 * 2
a3 = 2^2
As we can see, the 3 ^x is decreasing and the 2^ y is increasing
We need to play with the exponent in terms of n
Lets look at the exponent for the base of 2
a1 = 3^2 2^0
a2 = 3^1 2^1
a3 = 3^ 0 2^2
an = 3^ 2^(n-1)
I picked n-1 because that is where it starts 0
n = 1 (1-1) =0
n=2 (2-1) =1
n=3 (3-1) =2
Now we need to figure out the exponent for the 3 base
I will pick (3-n)
n =1 (3-1) =2
n =2 (3-2) =1
n=3 (3-3) =0
