Triangle is missing, so i have attached it.
Answer:
Radius = 10.82
Step-by-step explanation:
From the image attached, the triangle is obviously a right angle triangle and therefore, the missing side (AB) which is the radius can be found via pythagoras theorem.
We are given;
AC = 21
BC = 18
Thus;
|AC|² = |AB|² + |BC|²
21² = |AB|² + 18²
|AB|² = 441 - 324
AB = √117
AB = 10.82
Answer:
<em>Problem with the subtraction is </em><em>950 - 863 = 87.</em>
Step-by-step explanation:
Now let us suppose Tim began at number 863 and finished at number 950. The numbers 7 + 30 + 50, or 87 were added.
He later discovered that 863 + 87= 950.
<em>Therefore the problem with the subtraction is 950 - 863 = 87.</em>
Answer:
To determine the common ratio of a geometric sequence. You just need to divide any two consecutive terms on it. You can see below that all of them have the same quotient.
1.2 / 1.5 = 0.8
0.96 / 1.2 = 0.8
0.768 / 0.96 = 0.8
.
Decimal form = 0.8
Fraction form = 4/5
.
Check:
1.5 x 0.8 = 1.2
1.5 x 4/5 = 6/5 = 1 1/5 = 1.2
Therefore, the common ratio between successive terms in the sequence? 1.5, 1.2, 0.96, 0.768 is 0.8 or 4/5.
Answer:

Step-by-step explanation:
we have
-----> equation A
----> equation B
we know that
The solution of the system of equations is the point 
so
The solution of the equation
is equal to the x-coordinate of the solution of the system of equations
therefore
The solution is
