Using the given information, the value of a_{4} is 7401

<h3>Sequence</h3>

From the question, we are to determine the value of a_{4}

From the given information,

a_{n} = (a_{n-1})^{2} +5

Then we can write that

a_{4} = (a_{3})^{2}+5

a_{3} = (a_{2})^{2}+5

a_{2} = (a_{1})^{2}+5

Also, from the given information

a_{1} = 2

Then,

a_{2} = (a_{1})^{2}+5 becomes

a_{2} = (2)^{2}+5

a_{2} = 4+5

a_{2} = 9

Also,

a_{3} = (a_{2})^{2}+5 becomes

a_{3} = (9)^{2}+5

a_{3} = 81+5

a_{3} = 86

Then,

a_{4} = (a_{3})^{2}+5 becomes

a_{4} = (86)^{2}+5

a_{4} = 7396 +5

a_{4} = 7401

Hence, the value of a_{4} is 7401

Solve 5x(m+n) using the distributive property
Genrish500 [490]

Answer: 5xm+5xn

Step-by-step explanation:

For this exercise it is necessary to remember the following:

1) The Distributive Property states the following:

a(b+c)=ab+ac\\\\a(b-c)=ab-ac

2) The multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

Knowing this, and having the following expression given in the exercise:

5x(m+n)

You can apply the Distributive property multiplying m and n, which are inside the parentheses, by 5x.

So, you get the following result:

=(5x)(m)+(5x)(n)=5xm+5xn

What’s the answer and work for this?
sergeinik [125]

to find the value of x, you have to subtract 95 from 180. so the value of x will be 85. to find the value of y, you have to add the value of x which is 85 to the given angle which is 50. the angle would be 135. since the triangle is 180 degree, now u subtract 135 from 180. and the value of y will be 45. so x is 85 degree and y is 45 degree. hope that helps.
