The farmer will purchase five bags of kind A and six bags of type B.
Per bag, Type A includes 9 pounds of oats and 3 pounds of maize.
Per bag, Type B includes 2 pounds of oats and 10 pounds of maize.
The farmer is looking for a blend that comprises at least 57 pounds of oats and 75 pounds of maize.
Allow the farmer to mix type A feed = x pounds.
and feed type B = y pounds
(9x + 2y) pounds of oats when blended
Corn amount when combined: (3x + 10y) pounds
Oats equation: 9x + 2y = 57 ———— (1)
Corn equation: 3x + 10y = 75 ————- (2)
Subtract equation (2) from equation (2) by multiplying it by three (1)
3(3x + 10y) - (9x + 2y) = 75×3 - 57
9x + 30y - 9x - 2y = 225 - 57
28y = 168
y = 6 bags
derived from the equation (1)
9x + 2×6 = 57
9x + 12 = 57
9x = 57 - 12
9x = 45
x = 5 bags
Because the business has 15 bags of each sort, each bag costs $4.
As a result, the cost of 5 bags of type A and 6 bags of type B is = (54) + (64)
= 20 + 24
= $44
The farmer intends to buy five bags of kind A and six bags of type B.

a function is said to have a horizontal asymptote if either the limit at infinity exists or the limit at negative infinity exists. show that each of the following functions has a horizontal asymptote by calculating the given limit.
A function can only have two horizontal asymptotes, hence the answer is no. By examining the degrees of the numerator and denominator, one can find the horizontal asymptote of a rational function.
If limxf(x)=L or limxf(x)=L, a function f(x) will have the horizontal asymptote y=L. Therefore, we simply calculate the function's limit as it approaches infinity and again as it approaches negative infinity to locate horizontal asymptotes. Based on the degree of the numerator, n, and the degree of the denominator, m, horizontal asymptotes adhere to three principles. The horizontal asymptote is y = 0 if n m. The horizontal asymptote is y = a/b if n = m. There is no horizontal asymptote if n > m. As x gets closer to 0, we say that f(xlimit )'s is infinite. A boundary or a limit is now a number.

Using a linear function, it is found that her taxi ride was of 5 miles.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which the coefficients are described as follows:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the y-axis(x = 0).For the cost function, we have that:
The slope is the cost per mile, hence m = 3.75.The intercept is the flat fee, hence b = 1.10.Thus the cost for a ride of x miles is of:
C(x) = 3.75x + 1.10.
Her total fee was of $19.85, hence the mileage is found as follows:
19.85 = 3.75x + 1.10
x = (19.85 - 1.10)/3.75
x = 5 miles.
Which was the length of her taxi ride.

For the given function f(x), x-intercepts are 1,2 and 6 and the y-intercept is -12
Given :
[tex]f(x) = x^{3} -9x^{2} +20x -12 \\[/tex]
One of the factors of f(x) is (x-6)
Dividing f(x) by (x-6), we get :
[tex]\frac{x^{3} -9x^{2} +20x -12 \\}{x-6} = x^{2} -3x +2[/tex]
Now expanding, [tex]x^{2} -3x +2[/tex]
[tex]x^{2} -3x +2 = x^{2} -2x -x +2 =x(x-2) -(x-2) = (x-2)(x-1)[/tex]
Hence, [tex]x^{3} -9x^{2} +20x -12 = (x-6)(x-1)(x-2)[/tex]
For x-intercept, f(x) = 0 . Then
(x-6)(x-1)(x-2) =0
x = 1,2 and 6
For y-intercept, x=0 in f(x)
f(0) = -12
Hence, the x-intercepts are 1,2, and 6 and the y-intercept is -12.

Step-by-step explanation:
Custard is heated to a temperature of 180°F. It is then allowed to cool in a refrigerator whose temperature is 30°F. The custard cools to 120°F in 30 minutes. Determine how long will it take for the custard to cool to 50°F.
Answer: About 65 minutes.
It changes an average of about 60 degrees Fahrenheit every half hour.
180 120 60 50
0 30 60 65
Now it is about ten degrees until it's fifty. Since it takes thirty minutes to go down sixty degrees, divide sixty by ten to get six. Then divide thirty by six to get five. So, it should take about 65 minutes to cool down to 50 degrees.
It will take approximately 35 minutes for the custard to cool from 120°F to 50°F.
To determine how long it will take for the custard to cool to 50°F, we need to consider the rate at which it cools. From the given information, we know that the custard cools from 180°F to 120°F in 30 minutes.
To find the rate of cooling, we can calculate the temperature change per minute.
The temperature decreases by 180°F - 120°F = 60°F over 30 minutes. So, the rate of cooling is 60°F / 30 minutes = 2°F per minute. Now, let's use this rate to calculate how long it will take for the custard to cool from 120°F to 50°F.
The temperature difference between 120°F and 50°F is 120°F - 50°F = 70°F. To cool from 120°F to 50°F at a rate of 2°F per minute, it will take 70°F / 2°F per minute = 35 minutes.

What are the term values?In order to determine the term values, the rate of increase in the number of videos that Violet has at the end of each week has to be determined.
Rate of increase in the number of videos can be determined by dividing the change in the number of videos per week by the change in the number of weeks.
Rate of increase = change in the number of videos / change in the number of weeks
(10 - 6) / (2 - 1)

This indicates that if one of the sides is longer in length, then the measure of the angle opposite to it will also be longer.
The angles in the triangle TUV are denoted by the symbols T, U, and V.
The side that is UV, TV, and T U correspondingly is the side that is opposite to these angles.
The length of the opposing sides will immediately determine the measure of the angles, which will be directly proportionate to those angles.

A private university has a endowment fund that currently has 49 million dollars in it. if she invested in a one year cd that pays 5.12% interest compounded continuously, how much interest will it earn
If the university invest in a one year CD at 5.12% interest compounded continuously, the interest it will earn is determined by calculating as: Interest = Future value – Present value which would be $2.54 million
Continuously compounded interest means that a principal amount is constantly earning interest with infinite compounding periods for a certain time period. There are no increment compounding periods as with monthly or annually compounding.
The continuously compounding formula:
FV = PV* e^rt
Where FV is the future amount, PV is the initial amount, e is a mathematical constant (2.7183), r is the rate and t is the time period.
Hence,
FV = 49* 2.7183^(0.0512*1) =51.57
Interest earned= 51.57-49=2.54
Hence, the university will earn an interest of $2.54 million.
