Give the values a, b, and c needed to write the equations standard form. 2/3(x-4)(x+5)=1
Answers
ax ^ 2 + bx + c
What we must do in this case is to rewrite the given equation.
We have then:
2/3 (x-4) (x + 5) = 1
(x-4) (x + 5) = 3/2
(x ^ 2 + 5x-4x-20) = 3/2
2x ^ 2 + 2x-40 = 3
2x ^ 2 + 2x-43 = 0
Thus, the values of a, b and c are:
a = 2
b = 2

Write the first five terms of a sequence. Don’t make your sequence too simple. Write both an explicit formula and a recursive formula for a general term in the sequence. Explain in detail how you found both formulas.
Answers
The first five terms of a complex sequence are 4, 7, 10, 16, and 28.
Let's consider a non-trivial sequence.
Let's say the first term of our sequence, a1, is 4.
From then on, the sequence increases by 3 times the previous term, but instead of simply multiplying by 3, we will multiply by 3 raised to the power of one less than the term's position in the sequence. However, we are given that the general expression for the nth term is 4 + 3 x 2(n-2), except for the first term which remains 4.
This gives us a starting point for both our formulas.
To find the first five terms of this sequence, we can manually calculate them using the explicit formula given:
a1 = 4 (by definition)a2 = 4 + 3 x 2(2-2) = 4 + 3 x 1 = 7a3 = 4 + 3 x 2(3-2) = 4 + 3 x 2 = 10a4 = 4 + 3 x 2(4-2) = 4 + 3 x 4 = 16a5 = 4 + 3 x2(5-2) = 4 + 3 x 8 = 28Therefore, the first five terms are 4, 7, 10, 16, and 28.
Explicit Formula:
The explicit formula for any term an in the sequence is:
an = 4 + 3 x 2(n-2) for n > 1, with a1 = 4.
Recursive Formula:
The recursive formula builds each term based on the preceding term. For n > 1, the recursive formula is an = an-1 + 3 imes 2(n-2), with a1 still equal to 4.

what is the solution of the equation x^2-1=0
Answers
x^2 -1^2 = 0
(x + 1) (x - 1) = 0
x + 1 = 0 or x - 1 = 0
x = -1 or x = 1
Ans: -1 and 1
Solve it like this
x^2 - a^2 = (x + a)(x - a)
so for x^2 - 1 you get
(x + sqrt(1) ) (x - sqrt(1) = (x + 1)(x-1)
x^2 - 1 = (x + 1)(x - 1)
(x - 1)(x + 1) =0
x - 1 =0
x = 1

The ratio of two supplementary angles is 6:3. what is the measure of the smaller angle?
Answers
simplify
2:1
That means that the bigger angle is two times bigger than the smaller one
supplementary angles equal up to 180
smaller angle + larger angle = 180
s + l = 180
we can create our second equation using two times the smaller = larger
2s = l
our two equations are:
2s = l
s + l = 180
now that we have the two equations, we can solve using substitution to isolate the variable.
s + l = 180
s + (2s) = 180
simplify.
3s = 180
s = 60
the smaller angle has a value of 60.
now, remember that the larger angle is two times the smaller.
60 x 2 = 120
smaller angle: 60
larger angle: 120
we know this is correct because we know the smaller is 1/2 or 1:2 or 2:4 times the bigger, and the two angles add up to be 180 (60 + 120)

What is the volume of a rectangular prism with a length of 81\2 centimeters, width of 9 1\3 centimeters, and a height of 12 2\5 centimeters?

We must use a certain formula to find the volume of a rectangular prism. The formula is:
V = l × w × h
Let's multiply the 3 dimensions together. Before we can do that, though, we must convert the mixed fractions to improper fractions.
8 1/2 = (8 × 2) + 1 / 2 = 17/2
9 1/3 = (9 × 3) + 1 / 3 = 28/3
12 2/5 = (12 × 5) + 2 / 5 = 62/5
17/2 × 28/3 = 476/6 (which can be simplified to 238/3)
238/3 × 62/5 = 14756/15
Final Answer:
The volume of the rectangular prism is 983 11/15 centimetres cubed, and 983.733 centimetres cubed (Repeating decimal) as a decimal.

A hybrid car averages 609 miles on a 12.5 gallon tank of gas. Manuel is planning a 1290- mile vacation in his hybrid car. Find how many gallons of gas he can expect to burn.
Answers
1 miles = 12.5 / 609
1 mile = 0.0205 gallon
1290 miles = 0.0205 gallons x 1290
= 26. 48 gallons
Using ratio and proportion, we deduced that Manuel's hybrid car travels 48.72 miles per gallon. Based on this, we estimated that Manuel would need around 26.5 gallons of gas for his 1290-mile vacation.
Explanation:The subject at hand requires the utilization of ratio and proportion in mathematics, specifically in the context of fuel economy of cars. The hybrid car Manuel owns averages 609 miles on a 12.5 gallon tank. This implies that for every one gallon of gas, the car can travel 609 / 12.5 = 48.72 miles.
Now Manuel is planning for a 1290-mile trip. To ascertain how many gallons of gas he might expect to consume, we divide the total distance of the vacation by the miles per gallon for his car: 1290 miles / 48.72 miles/gallon = 26.5 gallons.
Therefore, Manuel can expect to consume approximately 26.5 gallons of gas for his 1290-mile vacation.

A sporting goods store offers a 40% discount on all golf clubs. Rocco spent 20% of the money in his savings account on a golf putter. He paid $48 for the putter after the discount. How much money did Rocco have in his savings before buyin the putter?
Answers
Rocco originally had $240
Explanation:
Before we begin, note that the price of the putter is given AFTER the discount. This means that the value of the discount doesn't affect the solution.
Assume that the amount Rocco had originally is x
Now, we are given that:
price of putter = $48
Price of putter represents 20% of what Rocco had
This means that:
price of putter = 20% * amount Rocco had
48 = 20% * x
48 = 0.2x
x = 48 / 0.2
x = $240
This means that Rocco originally had $240
