What logarithmic function represents the data in the table? x f(x) 25 2 125 3 625 4

Ray Of Light [21]

$\bf recall\\\\
log_{{ a}}{{ b}}=y \iff {{ a}}^y={{ b}}\qquad\qquad 
{{ a}}^y={{ b}}\iff log_{{ a}}{{ b}}=y \\\\
-----------------------------\\\\
thus\qquad 
\begin{array}{cc|llll}
x&y&5^y=x\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
25&2&5^2=25\\
125&3&5^3=125\\
625&4&5^4=625\\
\end{array}
\\\\\\
\textit{so hmmm what would that be in log notation? }\ 5^y=x \iff \boxed{?}$

Find two consecutive even integers such that four times the first plus three times the second is 20

Mila [183]

2 consecutive even integers : x and x + 2

4(x) + 3(x + 2) = 20
4x + 3x + 6 = 20
7x + 6 = 20
7x = 20 - 6
7x = 14
x = 14/7
x = 2

x + 2 = 2 + 2 = 4

so ur first number (x) = 2 and ur second number (x + 2) = 4

63 people

Step-by-step explanation:

Given parameters:

Number of students survey = 32

Number of those that liked ice-cream = 8

Total population size = 252

Unknown:

How many people in the population should prefer ice cream = ?

Solution:

From the survey;

8 out of 32 students prefer ice cream;

8 : 32

1: 4

This shows that 1 out of 4 students will prefer ice cream

NOw to the total population;

If out of 4 students, 1 prefers ice-cream;

Out of 252 students y will prefer ice-cream

Number of students that prefers ice-cream = $\frac{252}{4}$ = 63people
