$\frac{log 25}{log 8}$ is the expression Devonte used the change of base formula to approximate log Subscript 8 Baseline 25.

Given that, Devonte used the change of base formula to approximate log Subscript 8 Baseline 25.

We need to determine the expression did Devonte use.

<h3>What is the formula of change of base formula?</h3>

The change of base formula says $log_{a} b=\frac{log_{c}b }{log_{c}a}$ . It means to change the base of a logarithm logb b a, we just use division $\frac{log a}{log b}$ where these logarithms can have any positive number as a base.

Now, log Subscript 8 Baseline 25 $=log_{8}25$

$=\frac{log_{10}25 }{log_{10}8}=\frac{log 25}{log 8}$

Therefore, $\frac{log 25}{log 8}$ is the expression Devonte used the change of base formula to approximate log Subscript 8 Baseline 25.

Look at the following number sequence. 3, 7, 11, 15, . . . Based on the pattern, what are the next two terms?

viva [34]

So, if we look at the number pattern, we can see the numbers go up by 4.

The rule is Add 4.

So, to find the next two terms, we would add 4 to the last number shown, which is 15.

15 + 4 = 19

19 + 4 = 23

So, the next two terms are →19← and →23←.

Glad I could help, and good luck!

lorasvet [3.4K]

234 = a + s s = students a = adults
2a = s
after you get the equations you solve. plug 2a into the above equation.
so u get
234 = a + 2a
234=3a then divide 3 from each side
78 = a
so 78 adult tickets were sold

A circle has its center at (0,0) and passes through the point (0,9). What is the standard equation of the circle?

Alexxandr [17]

Answer:

x^2+y^2=9^2

Step-by-step explanation:

The standard equation of a circle is:

$(x-h)^2+(y-k)^2=r^2$

Where the center of a circle is (h,k) and r is the radius of the circle. In this case because a circle is equidistant from the center and we have a point where it passes through 9 that means that the radius is 9. However, since the standard equation states that we must write r in the form of $r^2$ this means that $r^2=9^2$ . Therefore by plugging in the values we have:
