Answer:
Obtuse and the rest of the question is incomplete.
Step-by-step explanation:
A student draws two parabolas on graph paper. Both parabolas cross the x-axis at (-4, 0) and (6, 0). The y-intercept
of the first parabola is (0, -12). The y-intercept of the second parabola is (0, -24). What is the positive difference
between the a values for the two functions that describe the parabolas? Write your answer as a decimal rounded to
the nearest tenth.
Answer:
1/2
Step-by-step explanation:
First parabola f(x1) = a ( x+4)(x-6) use point 0,-12 to find a = 1/2
= 1/2 (x+4)(x-6)
Second parabola a ( x+4) (x-6) using point 0, -24 shows a = 1
f(x2) = (1)(x+4)(x-6)
Difference between the 'a' values = 1 - 1/2 = 1/2

A hot dog vendor at the zoo recorded the average temperature in degrees, x, and the average number of hot dogs she sold, y.
The equation for the line of best fit for this situation is shown below.
[tex]\rm y=\dfrac{3}{10}x+8[/tex]
Based on the line of best fit, complete the given statements.
The expected number of hot dogs sold when the temperature is 50° would be___hot dogs.If the vendor sold 35 hot dogs, the temperature is expected to be ___degrees.Based on the line of best fit, for every 10-degree increase in temperature, she should sell____more hot dogs.We have a line of best fits:
[tex]\rm y=\dfrac{3}{10}x+8[/tex]
Plug x = 50 in the line of best fit.
y = (3/10)50 + 8
y = 15+8
y = 23
Plug y = 35
35 = (3/10)x + 8
27 = (3/10)x
x = 90 degree
Based on the line of best fit, for every 10-degree increase in temperature, she should sell 3 more hot dogs.
Thus, the expected number of hot dogs sold when the temperature is 50° would be 23 hot dogs, If the vendor sold 35 hot dogs, the temperature is expected to be 90 degrees, and based on the line of best fit, for every 10-degree increase in temperature, she should sell 3 more hot dogs.

Factor the binomial expansion. 81x4 – 648x3 + 1,944x2 – 2,592x + 1,296
Answer:
[tex]648[/tex]([tex]x^{3} + 3x^{2} - 4x + 2[/tex])
Step-by-step explanation:
When factoring an expression like this, you need to divide all of the parts by a common number or variable. In this case, the only thing all of these numbers share is that they are divisible by 648. So, you would divide each number by 648 to simplify it, getting 1, 3, 4, and 2. Put these numbers in front of their respective variables, and put 648 outside of the parentheses to get the final answer.

If Yang solves the inequality -4y> -40, then which of the following answers would be true for this claim?
Answer:
(a) 9, 8, 7, 6, 5, ...
Step-by-step explanation:
The solution to the inequality can be done a couple of ways. The solution is similar to that for a one-step linear equation.
__
reverse inequalityWe know that multiplying numbers by a negative value reverses their order. For example, 1 < 2, but -1 > -2. That is, multiplying by -1 requires a change in the comparison operator if it is to remain true.
For our inequality, we want to solve it by multiplying both sides by -1/4:
-4y > -40
(-1/4)(-4y) < (-1/4)(-40) . . . . . multiply both sides by -1/4 (reverses order)
y < 10 . . . . . . . . . . . simplify
The first few decreasing integer values that are part of this solution are ...
{9, 8, 7, 6, 5, ...}
__
make coefficients positiveWe can add 4y+40 to both sides of the inequality. The result will be an inequality with positive coefficients. This can be solved in one step.
-4y > -40 . . . . . given
(-4y) +(4y +40) > (-40) +(4y +40) . . . . . . add 4y+40 to both sides
40 > 4y . . . . . . . . . . . . . . . simplify
10 > y . . . . . . . . . . . . divide by 10 (order is unchanged)
y < 10 . . . . . . . . . rearrange to put y on the left
Integer solutions to this inequality are ...

On May 6, Jim Ryan borrowed $14,000 from Lane Bank at 712% interest. Jim plans to repay the loan on March 11. Assume the loan is on ordinary interest. How much will Jim repay on March 11?
The amount to be repaid by Jim Ryan is $14,891.78.
Given that, Principal (P) =$14,000, the rate of interest (R) =7[tex]\frac{1}{2}[/tex]% and T=310 days.
What is ordinary interest?Ordinary interest is calculated on the basis of a 360-day year or a 30-day month; exact interest is calculated on a 365-day year.
Now, the interest=14,000×7.5 %×[tex]\frac{310}{365}[/tex].
=$891.78
The amount to be repaid=14,000+891.78=$14,891.78

28 Pi
392 Pi

Therefore,
Radius (r) = d / 2Radius (r) = 7/2We know that :
V = πr^2hSubstituting the values :
>> V = π × (7 / 2)^2 × 8
>> V = π × (49 / 4) × 8
>> V = π × 49 × 2
>> V = 98π
Henceforth,
98 pi is the answer.We know , the volume of a cylinder is given by the formula – πr²h, where r is the radius of the cylinder and h is the height.
Diameter - 7Height - 8radius = 7/2Therefore, putting the values, we get,
