C because it would be 13 x 3 and then you would take that result and times it by 3 and so on and so on and this eventually after 10 hours results to C

Find the explicit formula for the given sequence 1/4, 3/4, 5/4, 7/4​
Harlamova29_29 [7]

Step-by-step explanation:

d=(3/4)-(1/4)=(5/4)-(3/4)=(7/4)-(5/4)=1/2

then it is an arithmetic sequence

by using this equation :

a(n) = a1 +(n-1)d

and we have : a1=(1/4),  d=(1/2)

So:

Explicit formula: a(n) = (1/4) +(n-1)*(1/2)

<em>hope this helps </em>

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> In x = 3
mixer [17]

Answer:

The solution is:

x = e^{3} = 20.09

Step-by-step explanation:

The first step to solve this equation is placing everything with the logarithmicto one side of the equality, and everything without the exponential to the other side. So

\ln{x} = 3

It already is in the desired format.

Now, we have that, since e and ln are inverse operations

e^{\ln{a}} = a

So, we apply the exponential to both sides of the equality

e^{\ln{x}} = e^{3}

x = e^{3} = 20.09

The equation in the given standard form is (x+10)^2+(y+6)^2=5^2

<h3>Equation of a circle</h3>

The standard equation of a circle is expressed as:

(x-a)^2+(y-b)^2=r^2

Given the equation x^2 + y^2 + 20x + 12y + 111 =0

Group the function to have:

(x^2 +20x)+(y^2+ 12y) + 111 =0

Complete the squares to have:

(x^2 +20x)+(y^2+ 12y) + 111 =0\\(x^2+20x+10^2-10^2)+(y^2+12y+6^2-6^2)+111=0\\(x+10)^2+(y+6)^2 -100-36+111=0\\(x+10)^2+(y+6)^2-25=0\\(x+10)^2+(y+6)^2=25\\(x+10)^2+(y+6)^2=5^2

Hence the equation in the given standard form is (x+10)^2+(y+6)^2=5^2
