Step-by-step explanation:
So, triangles are always 180 degrees in total, right?
One side is 31, and there is something on the edge indicating a 90 degree angle (right angle).
You can subtract both of these from 180, try! If you just want some of my thinking:
180-(31+90)=51
15x-1, so you must find what makes 52 because 52-1=51.
(sorry if this is a bit confusing)
Hope it helps, I'm only in 6th grade, this one took a little to solve!

What expression is equivalent to (x-3)^2
Answer:(x-3)(x-3)
Step-by-step explanation:
For each recursively-defined sequence below, write the first few term. Then use the terms to write an explicit equation.
a. a_1 = 15
a_n+1 = a_n - 3
b. t(n+1) = 1/3*t(n)
t(1)= 108
Answer:
Step-by-step explanation:
a_1 = 15
a_2 = a_1 - 3
a_2 = 15 - 3
a_2 = 12
a_3 = a_2 - 3
a_3 = 12 - 3
a_3 = 9
a_4 = a_3 - 3
a_4 = 9 - 3
a_4 = 6
a_5 = 3
a_6 = 0 I'm leaving these last two to expand
a_n = a1 - (n - 1)*d
a_n = 15 - (n - 1)*3
a_n = 15 - 3n + 3
a_n = 18 - 3n
Example
a_6 = 18 - 3*6
a_6 = 0
Problem B
t(1) = 108
t(1 + 1) = 1/3 * 108
t(2) = 36
t(3) = 1/3 * t2
t(3) = 1/3 * 36
t(3) = 12
t(4) =1/3 (t(3))
t(4) = 1/3 * 12
t(4) = 4
t(5) = t4 / 3
t(5) = 4 / 3
t(5) = 1.3333333
So the explicit definition is
t(n) = 108 (1/3)^(n - 1) You could simplify this a little bit by realizing that 108 is made of three 3s.
t(n) = 4 * 3^3 * (1/3)^(n - 1)
t(n) = 4 * (1/3) ^ (n - 4)
Example
t(5) = 108 (1/3)^4
t(5) = 108(1/81)
t(5) = 1.3333333
And using the simplified formula, you get.
t(5) = 4 * (1/3)^1
t(5) = 1.333333 which is the same thing as the original result.
Answer:
see explanation
Step-by-step explanation:
(a)
Using the recursive rule and a₁ = 15 , then
a₂ = a₁ - 3 = 15 - 3 = 12
a₃ = a₂ - 3 = 12 - 3 = 9
a₄ = a₃ - 3 = 9 - 3 = 6
The sequence is 15, 12, 9, 6, ....
This is an arithmetic sequence with n th term ( explicit rule )
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 15 and d = - 3 , then
[tex]a_{n}[/tex] = 15 - 3(n - 1) = 15 - 3n + 3 = 18 - 3n
----------------------------------------------------------------------
(b)
Using the recursive rule and t₁ = 108 , then
t₂ = [tex]\frac{1}{3}[/tex] t₁ = [tex]\frac{1}{3}[/tex] × 108 = 36
t₃ = [tex]\frac{1}{3}[/tex] t₂ = [tex]\frac{1}{3}[/tex] × 36 = 12
t₄ = [tex]\frac{1}{3}[/tex] t₃ = [tex]\frac{1}{3}[/tex] × 12 = 4
The sequence is 108, 36, 12, 4, ......
This is a geometric sequence with n th term
[tex]t_{n}[/tex] = t₁[tex](r)^{n-1}[/tex]
where t₁ is the first term and r the common ratio
Here t₁ = 108 and r = [tex]\frac{1}{3}[/tex] , then
[tex]t_{n}[/tex] = 108 [tex](\frac{1}{3}) ^{n-1}[/tex]

plz help, Randy is fencing off a semi-circular region in his backyard against a wall. The semi-circular region has a diameter of 24 feet. The fencing will go along the arc only. How much fencing does Randy need?
Answer:
[tex]Fence = 41.408ft[/tex]
Step-by-step explanation:
Given
[tex]d = 24ft[/tex]
Required
Determine the length of the wall
First, we calculate the circumference (C) of the semi-circle
[tex]C =\pi d[/tex]
[tex]C = 3.142 * 24[/tex]
[tex]C = 75.408[/tex]
The length of the fence is calculated by subtracting the diameter from the circumference:
[tex]Fence = C - d[/tex]
[tex]Fence = 75.408ft - 24ft[/tex]
[tex]Fence = 41.408ft[/tex]

4g + 12 < 60 solve and graph
Answer:
g<12
Step-by-step explanation:
4g+12<60
Subtract 12 from both sides.
4g<60−12
Subtract 12 from 60 to get 48.
4g<48
Divide both sides by 4. Since 4 is positive, the inequality direction remains the same.
g<48/4
Divide 48 by 4 to get 12.
g<12

How many more unit tiles must be added to the function
f(x)=x^2-6x+1 in order to complete the square?
0 1
06
o 8
O 9
Answer:
8
Step-by-step explanation:
How many more unit tiles must be added to the function
f(x)=x²-6x+1 in order to complete the square?
The easier, but usually not viable way: If we look at how many more tiles need to be added, we can see that each smaller sides is 1 unit. Thus, we need 8 more tiles to complete the square.
However, this is just an educated guess. If we didn't have a diagram or it was drawn badly, we would be wrong. Let's solve it algebraically.
Note:
completing the square is changing a quadratic equation (the format is
ax² + bx + c = 0)into a(x - d)² + e = 0. (an example of this is (a + b)² or (a - b)²)
This may be confusing, but look at an example:
x² + 4x + 4 = (x + 2)²
Also note that, (a - b)² = a² - 2ab + b²
If we substitute a = x, then we get:
x² - 2bx + b².
Now, all we need to do is find b.
If we know that 2bx = 6x, then we can divide both sides by 2x and get an answer of
2bx = 6x
b = 3.
Thus, b is 3.
Remember, to complete the square, we need to find b², which is
3² = 9.
Then, because they already give us a "1", we just need to add 9-1 = 8 more units.
Just in case, let's check the answer.
If we add 8 to the problem, we get:
x² - 6x + 1 + 8 =
x² - 6x + 9
As you can see, this follows the a² - 2ab + b² format, so we can factor it.
x² - 6x + 9 = (x - 3)²
This is a completed square. Thus, we need to add 8 more unit tiles.
We need to add 9 to the expression to complete the square.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To complete the square for the given function f(x) = x² - 6x + 1, we need to add a constant term that will make the expression a perfect square trinomial.
We can find this constant term by taking half of the coefficient of x and squaring it.
Half of -6 is -3, and (-3)² = 9.
So we need to add 9 to the expression:
f(x) = x² - 6x + 1 + 9
= (x - 3)² + 1
This expression is now a perfect square trinomial.
Thus,
We need to add 9 to the expression to complete the square.
