Answer:
b.332.2
Step-by-step explanation:
Explain how they are different AND the same
Proportional and linear functions are almost identical in form. The only difference is the addition of the “b” constant to the linear function. Indeed, a proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin
A redwood tree in King’s Canyon National Park, California has a circumference of 220 inches. Tanner measured the circumference of some other redwoods that had been planted over the last 5 years. His data is recorded below. Write a rule for the data in the table.
Use your rule to predict the circumference of a tree after 50 years of growth.
Use your rule to estimate the age of the tree with a circumference of 221 inches.
Answer:
A). 101 inches
B). 110 years
Step-by-step explanation:
Years since planting Circumference Difference
1 3 -
2 5 (5 - 3) = 2
3 7 (7 - 5) = 2
4 9 (9 - 7) = 2
5 11 (11 - 9) = 2
6 13 (13 - 11) = 2
There is a difference of 2 in every successive term of the circumference.
Therefore, the given sequence is an arithmetic sequence.
Explicit formula of an arithmetic sequence is given by,
[tex]A_n=a+(n-1)d[/tex]
Here a = first term
n = number of terms
d = common difference
From the given table,
[tex]A_n=3+(n-1)2[/tex]
[tex]A_n=2n+1[/tex]
Here [tex]A_n[/tex] = circumference after 'n' years
n = Age of the plant
By this formula,
Circumference of a tree after 50 years,
[tex]A_{50}=2(50)+1[/tex]
= 101 inches
Age of tree with the circumference = 221 inches,
221 = 2n + 1
2n = 220
n = 110 years

Answer:
The length of side of largest square is 15 inches
Step-by-step explanation:
The given suares are when joined in the way as shown in picture their sides form a right agnled triangle.
Area of square 1 and perimeter of square 2 will be used to calculate the sides of the triangle.
So,
Area of square 1: 81 square inches
[tex]s^2 = A\\s^2 = 81\\\sqrt{s^2} = \sqrt{81}\\s = 9[/tex]
Perimeter of square 2: 48 inches
[tex]4*side = P\\4* side = 48\\side = \frac{48}{4}\\side = 12\ inches[/tex]
We can see that a right angled triangle is formed.
Here
Base = 12 inches
Perpendicular = 9 inches
And the side of largest square will be hypotenuse.
Pythagoras theorem can be used to find the length.
[tex](H)^2 = (P)^2+(B)^2\\H^2 = (9)^2+(12)^2\\H^2 = 81+144\\H^2 = 225\\\sqrt{H^2} = \sqrt{225}\\H = 15[/tex]
Hence,
The length of side of largest square is 15 inches

Given the expression 11 + t/2 - 6, we are the find the output value when t = 5. To do that, we will simply substitute t = 5 into the given expression as shown;
f(t) = 11 + t/2 - 6
f(5) = 11 + 5/2 - 6
f(5) = 11 + 2.5 - 6
f(5) = 13.5 - 6
f(5) = 7.5
Hence the value of the function when t = 5 is 7.5

Which of the following is the quotient of the rational expressions shown below? Make sure your answer is in reduced form.
Answer:
The answer is B.
Step-by-step explanation:
First, you have to convert division into multiplication and cross out the common term :
[tex] \frac{3x - 6}{ {x}^{3} } \div \frac{x - 2}{2x - 1} [/tex]
[tex] \frac{3(x - 2)}{ {x}^{3} } \times \frac{2x - 1}{x - 2} [/tex]
[tex] \frac{3}{ {x}^{3} } \times (2x - 1)[/tex]
[tex] \frac{3(2x - 1)}{ {x}^{3} } [/tex]
[tex] \frac{6x - 3}{ {x}^{3} } [/tex]
The quotient of the rational expressions is [tex]\frac{6x - 3}{x^2}[/tex]
calculation:[tex]= \frac{3x - 6}{x^3}\div \frac{x-2}{2x - 1} \\\\= \frac{3(x - 2)}{x^3} \times \frac{2x-1}{x-2}\\\\ = \frac{3}{x^3} \times (2x - 1)\\\\= \frac{3(2x - 1)}{x^2}\\\\ = \frac{6x - 3}{x^2}[/tex]

Factor 5n^2 - 4n - 12 by grouping. Please show the steps.
Answer:
(n - 2)(5n + 6)
Step-by-step explanation:
Given
5n² - 4n - 12
Consider the factors of the product of the n² term and the constant term which sum to give the coefficient of the n- term
product = 5 × - 12 = - 60 and sum = - 4
The factors are - 10 and + 6
Use these factors to split the n- term
5n² - 10n + 6n - 12 ( factor the first/second and third/fourth terms )
= 5n(n - 2) + 6(n - 2) ← factor out (n - 2) from each term
= (n - 2)(5n + 6) ← in factored form

An isosceles triangle has base angles that each measure 23 degrees. Which equation can be used to find x, the measure of third angle of this isosceles triangle in degrees?
Answer:
since a triangle measures up to 180 degrees getting the value of x will be all angles added together equals to 180.
(base angles) + x = 180°
46° + x = 180°
this is what I think good luck
The measure of third angle of this isosceles triangle is 134 degrees.
What is Angle Sum Property?According to the triangle's "angle sum property," a triangle's interior angles add up to 180°.
S = (n-2)*180° is the angle sum property formula for any polygon, where 'n' represents the number of sides in the polygon.
Given:
Two Base angles is 23 degree.
and third angle is x.
Using Angle Sum property
x + 23+ 23 =180
x +46 =180
x= 180- 46
x= 134
Hence, the third angle is 134 degree.

Translate 7 units to the right and 4 units up.
Then, rotate 180° about the origin.
Answer:
Add 7 to the first value, 4 to the second, then flip the signs.
Step-by-step explanation:
Well we kind of need the current coordinates but I'll help to the extent I can!
In an ordered pair the first value is the (x) and the second is the (y) .
(x, y)
(x) is always the horizontal line (left & right).
(y) is always the vertical line (up & down).
So if you translate 7 units to the right, you'd add 7 to the (x) [First value in the ordered pair].
If you translate 4 units up, you'd add 4 to the (y) [Second value in ordered pair].
Now, rotating about the origin only changes whether the number is positive or negative.
If you rotate 180° it will just flip both of the values signs.
So if it was positive it becomes negative, if it was negative it becomes positive
Since I don't have the ordered pair I can't give you an answer but I can tell you what to do to get the answer.
Assuming it's a shape, for each point on the shape you will take it's coordinates, add 7 to the (x) and 4 to the (y), then flip the value sign.
Ex: If the starting coordinate was (-6, -3) we would add 7 to the (x), 4 to the (y) and get (-2, 4), flip the signs and end up with (2, -4).
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Answer:
y = 50x+25
f(x) = 50x+25
Step-by-step explanation:
Using the slope intercept form of the equation, y = mx+b
where x is the amount per day and b is the flat fee
2 days
125 = 2x+b
5 days
275 = 5x+b
Subtract
275 = 4x+b
125 = 2x+b
---------------------
150 = 3x
Divide by 3
150/3 = 3x/3
50 =x
The cost per day is 50 dollars
y = 50x +b
Using the data for 2 days
125 = 50*2 +b
125 = 100 +b
125-100 = b
b = 25
The equation is y = 50x+25
f(x) = 50x+25
To graph, The x axis is number of days and the y axis is total cost
The number of days starts with 0, which is the y intercept
Let x = 0, y =25
Using the slope, we go 50 up and 1 to the right ( 50 dollars per day)
The next point plotted ins ( 1,50)
Draw a straight line
Answer:
y = 50x+25
f(x) = 50x+25
