Givens
There are 127 floats this year.That represents 34 fewer floats than last year.The second given statement expresses that this year there are 34 LESS floats. So, to know how many floats were there last year, we just need to sum
[tex]127+34=161[/tex]
Therefore, last year were 161 floats, that is, 34 more than this year.
How do you find a literal equation for d=rt,
solve for t.
Answer: [tex]\frac{d}{r} = t[/tex]
Step-by-step explanation: To solve for t in the equation d = rt, all we have to do is get t by itself on the right side of the equation.
Since t is being multiplied by r, we simply divide both sides of the equation by r. On the right, the r's cancel and we are left with r.
On the left side of the equation we have [tex]\frac{d}{r}[/tex].
Therefore, our answer is [tex]\frac{d}{r} = t[/tex].

Answer:
a, b, c
Step-by-step explanation:
f(x) = 3(1/4)^x
a. (-2, 48)
f(-2) = 3(1/4)^(-2) = 3(4)^2 = 3 * 16 = 48
(-2, 48) is on the graph.
b. (0, 3)
f(0) = 3(1/4)^(0) = 3(1) = 3
(0, 3) is on the graph.
c. (2, 3/16)
f(2) = 3(1/4)^(2) = 3(1/16) = 3/16
(2, 3/16) is on the graph.
d. (12, 0)
f(12) = 3(1/4)^(12) = 3(0.000000596)
f(12) does not equal zero.
(12, 0) is not correct
Solve - ( c - 3) = 6
A college student borrows $3,000 for 3 months to pay for a semester of school. If the interest is $61.88 find the monthly payment
The student must make monthly payments of $1,020.63 to repay the $3,000 loan with $61.88 in interest over 3 months.
The student has borrowed $3,000 for 3 months and the interest incurred on this loan is $61.88. To find the monthly payment, we need to add the total interest to the principal borrowed and then divide it by the number of payments (which is 3 in this case).
The total repayment amount is calculated as $3,000 principal + $61.88 interest = $3,061.88.
Now, we divide the total repayment amount by the number of monthly payments:
Monthly Payment = Total Repayment Amount / Number of Payments
Monthly Payment = $3,061.88 / 3
Monthly Payment = $1,020.63
Therefore, the student will need to make monthly payments of $1,020.63 to repay the $3,000 loan over 3 months.

If you shift the quadratic parent function, f(x) = x2, right 12 units, what is the equation of the new function?
A. g(x) = (x – 12)2
B. g(x) = (x + 12)2
C. g(x) = x2 – 12
D. g(x) = x2
Answer:
A. [tex]f(x) = (x-12)^2[/tex]
Step-by-step explanation:
The parent function [tex]f(x) = x^2[/tex] can be shifted 12 units to the right by moving its vertex 12 units to the right. The parent function has a vertex at (0,0) since [tex]f(0) = 0^2=0[/tex]. It will shift to (12,0) so [tex]f(12) =(12-a)^2=0[/tex]. The only value of a which will make it 0 is 12. So the equation is [tex]f(x) = (x-12)^2[/tex]

A train leaves chicago and travels east at 60 mph. another train at the same depot leaves at the same time and travels west at 72 mph. how long before the two trains are 330 miles apart?
The two trains will be 330 miles apart after 2.5 hours.
Explanation:To find how long it takes for the two trains to be 330 miles apart, we can apply the formula for relative velocity:
Relative velocity = sum of their speeds
The first train is moving east at 60 mph, and the second train is moving west at 72 mph. So their relative velocity is 60 mph + 72 mph = 132 mph.
To find the time it takes for the trains to be 330 miles apart, we can use the formula:
Distance = speed × time
330 miles = 132 mph × time
Solving for time, we have:
Time = 330 miles / 132 mph = 2.5 hours

Assume the ball passes through the points (3,8), (5,20/3), and (6,5) . Use this data to set up a system of three equations and three unknowns (a, b, and c) that will allow you to find the equation of the parabola. Write the system in the space provided.
To solve this question:
First, we need to know the standard equation of a parabola.Then, with the three points given, we can build a system of three equations.Doing this, we get that the system is, with the 3 equations:
[tex]9a^2 + 3b + c = 8[/tex]
[tex]75a + 15b + 3c = 20[/tex]
[tex]36a + 6b + c = 5[/tex]
Equation of a parabola:
A parabola is a second degree polynomial, having an standard equation of:
[tex]y = ax^2 + bx + c, a \neq 0[/tex]
Point (3,8)
This means that when [tex]x = 3, y = 8[/tex]. So
[tex]y = ax^2 + bx + c, a \neq 0[/tex]
[tex]8 = a\times3^2 + 3b + c[/tex]
[tex]9a^2 + 3b + c = 8[/tex]
Thus, [tex]9a^2 + 3b + c = 8[/tex] is the first equation.
(5,20/3)
This means that when [tex]x = 5, y = \frac{20}{3}[/tex]. Thus
[tex]y = ax^2 + bx + c, a \neq 0[/tex]
[tex]\frac{20}{3} = a\times5^2 + 5b + c[/tex]
[tex]25a + 5b + c = \frac{20}{3}[/tex]
[tex]75a + 15b + 3c = 20[/tex]
Thus, [tex]75a + 15b + 3c = 20[/tex] is the second equation.
(6,5)
This means that when [tex]x = 6, y = 5[/tex]. Thus
[tex]y = ax^2 + bx + c, a \neq 0[/tex]
[tex]5 = a\times6^2 + 6b + c[/tex]
[tex]36a + 6b + c = 5[/tex]
Thus, [tex]36a + 6b + c = 5[/tex] is the third equation.
After all, the system of equations is:
[tex]9a^2 + 3b + c = 8[/tex]
[tex]75a + 15b + 3c = 20[/tex]
[tex]36a + 6b + c = 5[/tex]

What is the length, in units, of the hypotenuse of a right triangle if each of the two legs is 2 units?
4 units
2 units
Square root of 6 units
Square root of 8 units
Answer:
square root of 8
Step-by-step explanation:
because it is 8 squared
The length of the hypotenuse of a right triangle with legs of 2 units each is the square root of 8 units.
Explanation:In a right triangle, the length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. If each of the two legs is 2 units, then the length of the hypotenuse can be found as follows:
hypotenuse2 = leg12 + leg22
hypotenuse2 = 22 + 22
hypotenuse2 = 4 + 4
hypotenuse2 = 8
Therefore, the length of the hypotenuse is the square root of 8 units.
