Because you use trial and error to see what x is and it says integet meaning 1,2,3,4,5,6... and their opposites.
Answer:
x ≈ 5 using math and x ≈ 4 using trial and error
Step-by-step explanation:
[tex]6^x = 3800[/tex]
[tex]x = log_{6}*3800[/tex]
x ≈ 4.6 ≈ 5
Hope this helped!
-----------------------------------------------------------------------------------------------
Trial and Error:
6 ^ 4 = 1276
6 ^ 5 = 7776
3800 is closer to 1276, so x = 4

The hypotenuse of a right triangle is 35 in. One leg of the triangle
measures 21 in. What is the length, in inches, of the other leg of
the triangle?
Answer:
28 in
Step-by-step explanation:
Use Pythagoras Theorem
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
Where c is the hypotenuse of the right angle triangle ,and a and b the other sides. Just substitute the values and get your answer.
The length of a side of a square is 4x – 1.
Express the area of the square in terms of x.
Answer:
16x^2 - 8x + 1
Step-by-step explanation:
1. The area of a square can be represented as s^2 or (s)(s), where s = side.
2. (Solving)
Step 1: Set up expression
[tex](4x-1)^2[/tex] [tex](4x-1)(4x-1)[/tex]Step 2: Apply the FOIL method (first, outside, inside, last)
[tex](4x)(4x)+(4x)(-1)+(-1)(4x)+(-1)(-1)[/tex] [tex]16x^2 -4x -4x +1[/tex]Step 3: Simplify.
[tex](16x^2)+(-4x-4x)+(1)[/tex] [tex]16x^2 -8x + 1[/tex]Therefore, the area of the square in terms of x is 16x^2 - 8x + 1.
Name 3 points that are coplanar
6. Tell whether the lines are parallel, perpendicular, or neither. *
Line 1: (-3,-1) and (-7,-2)
Line 2: (2.-1) and (8,4)
Parallel with a slope of 1/4
Parallel with a slope of 5/6
Perpendicular with a slope of 1/4 and
Perpendicular with a slope of 1/4
Neither, slopes are 1/4 and 5/6
O
Neither, slopes are 3/10 and 1/2
Answer:
Neither, slopes are 1/4 and 5/6
Step-by-step explanation:
Let's find the slope for Line 1: (-3,-1) and (-7,-2)
m1 = (-2+1)/ (-7+3)
= -1/-4
=1/4
Line 2: (2.-1) and (8,4)
m2= (-4+1)/ (8-2)
= -3/6
= - 1/2
These slope values are not the same, so the lines are not parallel. The slope values are also not negative reciprocals, so the lines are not perpendicular. Then the answer is
Neither, slopes are 1/4 and 5/6

Joe is training for a marathon. He plans to run 4 miles every day (d). In order to feel prepared, his goal is to run at least 60 miles before the race.
Write an inequality to represent how many days he will need to run in order to meet his goal.
Answer:
Step-by-step explanation: 4x15 =60
The inequality which represents the number days Joe will need to to run in order to meet his goal is [tex]4d\geq 60[/tex].
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is called inequality.
According to the given question.
Joe plans to run 4 miles every day.
And his goal is to run at least 60 miles.
Let Joe needs d days to run.
Therefore, according to the given condition the inequality which represents the number days Joe need to run in order to meet his goal is given by

do logarithmic functions have horizontal asymptotes?
9514 1404 393
Answer:
not generally
Step-by-step explanation:
The basic log function has a vertical asymptote where its argument is zero. It has a positive slope for all positive arguments. It tends to infinity as the argument tends to infinity. There is no horizontal asymptote.
__
A log function can be made part of a larger expression in a way that would give the expression a horizontal asymptote. For example, the function ...
f(x) = 1/log(x)
has a horizontal asymptote at f(x) = 0. (This asymptote is approached very slowly.)

Solve the formula c = 5p + 215 for p
Answer:
1/5c -43 =p
Step-by-step explanation:
c = 5p + 215
Subtract 215 from each side
c-215 = 5p +215-215
c-215 = 5p
Divide each side by 5
c/5 -215/5 = 5p/5
1/5c -43 =p

Answer:
11.7
Step-by-step explanation:
Step 1: Our output value 39.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 39 = 100%.
Step 4: Similarly, x = 30%.
Step 5: This results in a pair of simple equations:
39 = 100%(1)
x = 30%(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
39/x = 100%/30%
Step 7: Again, the reciprocal of both sides gives
x/39 = 30/100
------> x = 11.7
Therefore, 30% of 39 is 11.7

Formula in finding the trapezoid's area:
USE THIS FORMULA!: 1/2 × altitude × (base [tex]_{1}[/tex] + base [tex]_{2}[/tex])(note: altitude is also known as the height)
Area = 1/2 × 5 × (6 + 8)
A = 1/2 × 5 × 14

Answer:
Reflexive property
Step-by-step explanation:
The reflexive property of congruence states that any geometric shape is congruent to itself.
Answer:
C) Symmetric Property
Step-by-step explanation:
The Symmetric Property states that If A is congruent to B, then B is also congruent to A. This implies that the congruence is symmetric.
Khan Academy also states that:
When a relation has a symmetric property, it means that the if relation is true between two things, it is true in either order. If VW ≅ XY, then XY ≅ VW.
Therefore, the correct answer is C) Symmetric Property.
