Answer:
Y'=3xy-3x-12
Y'=F(-2,-1)=0
Step-by-step explanation:
The function of the equation at the point (-2,-1)
is where the equation make the function go to zero:
Y'=3xy-3x-12
Y'=F(-2,-1)=[3(-2)(-1)]-[3(-1)]-12
F(-2,-1)=[6]-[-6]-12
F(-2,-1)=6+6-12
F(-2,-1)=12-12
F(-2,-1)=0
Solving for y
3xy-3x-12=0
y=4/x+x
Making y=0
So the values make the function go to zero
Answer: The TV is 48 inches wide.
Step-by-step explanation: To find the solution to this equation we must use the Pythagorean theorem. The Py. Theo. is basically the formula :
a^2 + b^2 = c^2 You say this as "A squared plus b squared equals c squared"
To use this formula you must plug in the given values of a and b, to find c. A and b represent the two bases of the triangle, while c is the hypotenuse. In this equation we already have the value of c and a. We need to find b, but in order to do that we use a different formula. We use : c^2 - a^2 = b^2
See :
52^2 - 20^2 = b^2 *The ^2 means "to the power of" aka an exponent*
2704 - 400 = b^2 *When dealing with ^2, all you do is multiply the number by itself*
2304 = b^2 *Next, we find the square root of our current number.*
48 = b
*Another way to solve this equation is to memorize all the Pythagorean Triples. With that knowledge, you wont even need to use the formula because you will already know all three values. I hope this helped you understand :)
The amount that will be expected to be paid for the bonds that are bought will be C. $3,318.33
<h3>How to calculate the amount of bonds?</h3>
From the information given, the bonds from the city of tavel gorge worth $1,000 each are selling at 110.611 and Sean wishes to purchase three such bonds.
Therefore, the amount for the bonds will be:
= 1110.611 × 3
= 3,318.33
In conclusion, the correct option is C.

Answer:
-1
Step-by-step explanation:
mn = -3 because 3 × -1 = -3
p^2 = 4 because 2^2 = 4
Then 4 + -3 = -1
Answer:
704 square yards
Step-by-step explanation:
10 * 19 = 190
190 * 2 = 380
12 * 19 = 228
12 / 2 = 6
6 * 8 = 48
48 * 2 = 96
96 + 228 + 380 = <em><u>704</u></em>
