Evaluate each logarithm.
log₂ 16
The answer to the given logarithm expression is log₂ 16 = 4
A power to which a number must be increased in order to achieve another value is referred to as a logarithm. The easiest way to represent enormous numbers is in this way.
The fact that addition and subtraction logarithms can be used to multiply and divide logarithms is supported by a number of significant features of logarithms. The use of logarithmic operations is subject to a set of rules. These guidelines are known as: Division regulations apply to products. Exponential/Power Law Changes to fundamental laws Rule of Base Change Log elaboration
We need to evaluate log₂ 16
Using the property logₐ (mⁿ) = n logₐ m
16 = 2⁴log₃ 125 can be written as
log₂ 16 = 4 log₂ 2
We know that logₐ a = 14 log₂ 2= 4
Hence , we evaluated the logarithm which is log₂ 16 = 4

and a ride costs $1.
1. Write an equation to represent the relationship between the dollar amount Kiran is
spending and the number of games, , and the number of rides, , he could do.
2. Which graph represents the relationship between the quantities in this situation?
Explain how you know.
The equation to represent the relationship between the dollar amount Kiran is spending and the number of games and the number of rides is 0.25x + y = 12
The graph that represents the relationship between the quantities in this situation is graph C.
How to illustrate the information?It should be noted that the equation will be:
25x + 100y = 1200 in cents
or 0.25 x + y = 12 in dollars
where
x= games
y= rides
The graph that will connect the x axis and y axis at the points where x= 48 and y= 12, Only graph C seems to have a line that may end at x=48. Therefore, the correct option is C.

Divide. Rationalize all denominators. ∛6 x² y⁴ / 2∛5 x⁷y
The value of the expression [tex]\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex] after rationalizing the denominator is [tex]\frac{5^{\frac{2}{3}}y^{3}}{10x^{5}}[/tex].
A finite collection of symbols that is well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.
Rationalizing the denominator is the process of shifting a root, such as a cube root or a square root, from the fraction's denominator to its numerator (numerator).
The numerator is the part of a fraction that comes before the vinculum.
The denominator of a fraction is the phrase that comes before the vinculum.
Consider the expression,
[tex]\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex]
Now, let [tex]a=\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex]
[tex]a=\frac{(x^{2}y)(y^{3})}{2\sqrt[3]{5} (x^{2}y)(x^{5})}[/tex]
[tex]a=\frac{y^{3}}{2\sqrt[3]{5} {~}x^{5} }[/tex]
To rationalize the denominator we multiply and divide the expression by ( ∛5 )².
[tex]a=\frac{y^{3}}{2\sqrt[3]{5} {~}x^{5} } \times \frac{(\sqrt[3]{5})^{2}}{(\sqrt[3]{5})^{2}}[/tex]

A fraction is represented inside the form of 'x/y', wherein 'x' is the numerator and 'y' is the denominator. The numerator represents the entire variety of parts taken into consideration. whereas, the denominator represents the full quantity of equal components in a fraction. The pinnacle quantity in a fragment is usually taken into consideration as a numerator.
Another phrase for a denominator is the divisor. both of those words check with the range beneath the road in a not unusual fraction. similarly, while you're speakme approximately statistical values, a denominator refers back to the whole number or population from which samples are taken.
In a fallacious fraction, the numerator is extra than or the same as the denominator and the denominator must not be the same as zero. In an incorrect fraction, the numerator is less than the denominator and the numerator is extra than 0. In an unsuitable fraction, the numerator is constantly more than the denominator.

she ordered. how many party favors
did anna receive?
Answer: 20
Step-by-step explanation: She received 1/10 of the party favors, and 1/10 of 200 is 20.
Anna ordered 200 party favors, she received only 1/10 of the party favors
she ordered, i.e., Anna received 20 party favors.
Here, given that, Anna ordered 200 party favors. she received only 1/10 of the party favors she ordered.
Now, we have to find out how many party favors Anna received,
we need to calculate 1/10 of the total number of party favors she ordered.
Anna ordered 200 party favors, and she received only 1/10 of that amount.
As, we know that, 'of' indicates 'multiplication'
so, we have to find 1/10 of 200, so that, we multiply 200 by 1/10:
1/10 * 200
= 200/10
= 20
i.e. She received 1/10 of the party favors, and 1/10 of 200 is 20.
So, Anna received 20 party favors.

Solve each equation. If necessary, round to the nearest ten-thousandth. log (5 x-4)=3
The solution of the given equation by rounding off it to the nearest ten-thousandth is 4.8170.
What is a round-off of the digit?
In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.
For eg: 13.58 ~ 13.6
Solving the given equation: - log (5x - 4)=3
We are given a logarithmic expression: log (5x - 4)=3
We know that e^(log b) = b
Using exponential on both sides, we have
e^(log (5x - 4)) = e^3
5x - 4 = 20.085
5x = 24.085
x = 4.817
Hence, the solution of the given equation rounded off to the nearest ten-thousandth is 4.8170.

How to solve simultaneous equations?Simultaneous equations are solved by any three (3) of the following methods.
Substiution method, Elimination method and Graphical methodHow to solve the given simultaneous equations by graphical methods?Given the simultaneous equations
x + y = 6 and y = x
We first confirm the solution by using the substitution method.
Substiutitng y = x into the first equation, we have
x + y = 6
x + x = 6
2x = 6
x = 6/2
x = 3
Since y = x. So, y = 3.
So, the solution is x = 3 and y = 3.
So, for a graphical solution, plotting the graph of
y = x and x + y = 6 on the x and y axis, their point of intersection is at the point (3, 3)So, the graphical solution of the simultaneous equation is

Using Company A's calling plan, the cost of an overseas phone call is a $0.95 connection fee plus 18 cents per minute. If the total cost of the call is $2.75, how long is the phone call?
The total duration of the phone call was 10 minutes.
Given that, by using Company A's calling plan, the cost of an overseas phone call is a $0.95 connection fee plus 18 cents per minute. If the total cost of the call is $2.75 and we have to calculate the time how long was the phone call.
Let the number of minutes a phone call held be x.
Now, we will be representing the above given information in terms of linear equation and then solve for the value of x which will give us the number of minutes the phone call held.
Total cost = $0.95 + $0.18x
$2.75 = $0.95 + $0.18x
2.75 = 0.95 + 0.18x
2.75 - 0.95 = 0.18x
1.8 = 0.18x
1.8/0.18 = x
10 = x
Therefore, the call will go 10 minutes long.

The price of each souvenirs is 28.33 Dollars.
Let X be the same price of all the t-shirts and all the baseball caps.
Lacey purchased
4 T-shirts and 2 Baseball caps = $162
4X + 2X = $162
6X = $162
Anna purchased
1 T-shirt and 2 Baseball caps = $93
1X + 2X = $93
3X= $93
Now we will add the price of souvenirs purchased by Lacey and Anna to find the price each souvenir.
6X = $162 eq. 1
3X= $93 eq. 2
As we have two equations we will add both equations :
6X + 3X = $162 + $93
Then we will determine the value of X .
9X = $255
X = $255 ÷ 9
X = $28.33
Hence the price of each souvenirs is $28.33 .
