a) To create an equation
X+X =7
so what's X over here is
7² = x²
X=3.5
b) Real numbers are mixture of irrational and rational numbers so √5 and √6 are irrational where as 5 and 6 are not but they two are equal to each other.
Explaining the equation:
√5 +√6 = √11
5 +6 = 11
√11 =11
√= 11 ÷ 11
√= 1
So if root is 1 then -1 is -√
this is the answer propably
Answer:
Less than 5
Step-by-step explanation:
The eason behind the answer being less than 5 is because if you multiply something by a fraction that is less than a whole number, then you will get less than the original number you multiplied the fraction with.
Hope this helps :)
BC = 12; XZ = 8; BZX = 55
To find BC:
Since XY is the bisector of AB and AC, this means that it is a median of triangle ABC. Its length will be half of the length of BC; 6 = 1/2BC; 6*2 = BC; 12 = BC
To find XZ:
Since XZ is the bisector of AB and BC, this means that it is a median of triangle ABC. Its length will be half of the length of AC; 1/2(16) = 8.
To find BZX:
XYCZ is a parallelogram. Consecutive angles of a parallelogram are supplementary; 180-55=125=XZC.
XZC and BZX form a linear pair and are thus supplementary. This means that BZX = 180-XZC = 180-125 = 55
Answer: f(x) = 61(3.5)^x
Step-by-step explanation:
This is what the variables always mean in the function:
a = initial value
b = growth factor
x = time
Then, you just plug them in! Hope this helps.
Answer:
Proved below
Step-by-step explanation:
If we assume that n + 1 even when n is even, it means that;
n + 1 = 2x
Where x is an integer
Then;
n = 2x - 1
This means that n is odd because 2x - 1 is odd.
But we know that n is even, thus, our assumption is wrong.
Therefore, n + 1 is odd when n is even.
