Therefore v = log(62) / log(17) is the solution for v, the unknown variable in the equation.
Define log(Logarithm).The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be increased in order to obtain a number x is the logarithm of x to the base b. For example, since 1000 = 10³, the logarithm base 10 of 1000 is 3, or log₁₀ = 3.
What is a function?A function in mathematics is an expression, rule, or law that establishes the connection between an independent variable and a dependent variable (the dependent variable). Each element of X receives precisely one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
To solve this exponential equation, we can use the logarithms property that is log(a^b) = b*log(a).
Given the equation 17v = 62, we can take the logarithm base 17 of both sides:
log(17^v) = log(62)
v*log(17) = log(62)
Dividing both sides by log(17) gives us:
v = log(62) / log(17)
This is the solution for v, the unknown variable in the equation.

Find the distance between the points.
(-6,5),(-6,-3.5)
The distance is
Answer:
8.5
Step-by-step explanation:
there's a rule to get the distance between 2 points
√((1st x- 2nd x)²+(1st y- 2nd y)²)
√((-6-(-6))²+(5-(-3.5))²)
=√((-6+6))²+(5+3.5))²)
you can just type that on your calculator and you'll get the result
√((-6+6))²+(5+3.5))²)
=√((5+3.5))²)
= √((8.5))²)
the root goes away with the power (exponent)
so it equals 8.5

What is linear pair angles?Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°.
Given is a figure of angles showing the pair of linear angles.
Therefore, by the definition of linear pair angles,
∠ 1 + 111.3° = 180°
∠ 1 = 180° - 111.3°
∠ 1 = 68.7°
Hence, the measure of ∠ 1 is 68.7°

The wall paper Jeff wants to use comes in rolls that are 1 yard wide and 10 yards long. How many square feet of wall paper are in each roll?
Answer:
Each roll of wallpaper has an area of 90 square feet.
Step-by-step explanation:
In order to find the number of square feet of wallpaper in each roll, we first need to calculate the total area of the wallpaper in the roll. The area is the product of the length and width of the roll.
The width of each roll is 1 yard, and the length of each roll is 10 yards.
Area of the wallpaper = width x length = 1 yard x 10 yards = 10 square yards
Now we need to convert the area from square yards to square feet, as the area of wallpaper is usually measured in square feet.
1 yard = 3 feet
So we need to multiply the area in square yards by the conversion factor, which is 9.
10 square yards = 10 square yard * 9 = 90 square feet
Therefore, each roll of wallpaper has an area of 90 square feet.
It's important to note that while calculating, the units should be consistent i.e area of a length (yard) multiplied with a width(yard) will give the area in square yards, which we converted to square feet by considering the conversion factor of 1 yard = 3 feet.

Answer:
Jim bought the used RV at a price of $ 6,485 under its book price.
Step-by-step explanation:
Given that Jim Clinnin purchased a used RV with 18,500 miles for $ 46,400, and originally the RV sold for $ 67,500 with a residual value of $ 19,500 and, after subtracting the residual value, depreciation allowance per mile was $ 0.79, to determine how much was Jim's purchase price over or below the book value the following calculation must be performed:
18,500 x 0.79 = 14615
67,500 - 14,615 = X
52.885 = X
52,885 - 46,400 = 6,485
Therefore, Jim bought the used RV at a price of $ 6,485 under its book price.

Step-by-step explanation:
The fourth term of an arithmetic sequence is 20. The common difference is -1/5 times the first term. What is the first term? Graph the sequence.
As a result, the first term of the answer to the given arithmetic mean problem is 14.
What does arithmetic mean?The Arithmetic Mean or Average of the Group is the product of the sum of all the numbers in a group and the amount of items in that list, divided by both. The Geometric progression is also same as this .This average of the numbers 5, 7, and 9 is, for instance, 4, as 5 + 7 + 9 is 21, and 21 split by 3 [there really are three numbers] equals 7.
Here,
In this case, t(n) = (a + ((n — 1) * d)),
The value of the nth term is t(n),
The first term of the AS is a.
The position of a value in the A.S. is represented by the positive whole integer n, and
The constant common difference among A.S. words is d.
In light of the question, we can say:
11 = (5 + ((4 — 1) * d)),
Take 5 away from both sides.
11 — 5 = (5 + ((4 — 1) * d)) — 5,
On the RHS, the fives cancel one another out.
6 = 3d,
d = 2.
In summary, the common distinction is: 2.
=> 20 = a + 3d
=> 20 - 6
=> a =14
As a result, the first term of the answer to the given arithmetic mean problem is 14.

Use SOH-CAH-TOA (O=opposite, A=adjacent, H=hypotenuse) we see that they give us the angle missing, x, but we first need to identify what method to use. They give us the opposite side from the angle, and they also give us the adjacent side from the angle, so TOA=tan.
now plug it in, since there is no angle then we plug it in as [tex]tan^{-1}=\frac{10}{11}[/tex]

Kemi is used division to write a fraction equivalent to 30/100. She tried to divide the numerator and denominator by 3. She got stuck what advice would u give her?
Answer: She can multiply the numerator and the denominator by the same number. For example, 30/100 × 2/2
So what you're doing multiplying the numerator & the denominator each by 2. 30 ×2 = 60 and 100 x 2 = 200, ending up with 60/200.
when reduced it would simplify back to 30/100.
You can do the same for each similar. Problem asking for an equivalent. Just multiply both the numerator and denominatorby the same number.

find,

when

Answer:
x = 400 when y = 100
Step-by-step explanation:
This is a question in relation to direct variation.
y ∝ [tex]\sqrt{x}[/tex]
y = k [tex]\sqrt{x}[/tex]
Given that, y = 45, x = 81. Then;
45 = k [tex]\sqrt{81}[/tex]
45 = 9k
k = [tex]\frac{45}{9}[/tex]
k = 5
Thus the relationship among the variables is;
y = 5 [tex]\sqrt{x}[/tex]
If y = 100, then;
100 = 5 [tex]\sqrt{x}[/tex]
[tex]\sqrt{x}[/tex] = [tex]\frac{100}{5}[/tex]
[tex]\sqrt{x}[/tex] = 20
x = [tex](20)^{2}[/tex]
x = 400
Therefore, x = 400 when y = 100.

For problems 1–4, solve the given system of equations using either substitution or elimination.
Answer:
1. -3, -2
2. 2, -7
3. 1, 2.5
4. infinitely many solutions
Answer:
1. (-3,-2)
2. (1, -7)
3. (1, 2.5)
4. No solution
Step-by-step explanation:
Number 1: Substitution
Plug y in to substitute and get
2x + (2x + 4) = -8
4x + 4 = -8
4x = -12
x = -3
Then plug into the y equation
y = 2(-3) + 4
y = -6 + 4
y = -2
(-3, -2)
Number 2: Elimination
Begin eliminating by crossing out same values
40x + 12y = -44
-2y = 14
Solve for y
-2y = 14
y = -7
Solve for x
40x + 12(-7) = -44
40x - 84 = -44
40x = 40
x = 1
(1, -7)
Number 3: Elimination
Add the two and get:
-3x + 2y = 2
6y = 15
Solve for y:
6y = 15
y = 5/2
Solve for x:
3x + 4(5/2) = 13
3x + 10 = 13
3x = 3
x = 1
(1, 2.5)
Number 4: Substitution
Solving for y to begin with:
4x - y = -3
-y = -3 - 4x
y = 3 + 4x
Then solve for y in the second system
-8x + 2y = 6
2y = 6 + 8x
y = 3 + 4x
Set equal to each other
3 + 4x = 4 + 4x
3 = 4
