Answer:
y = 3/4x - 2
Step-by-step explanation:
Given:
m = 3/4
b = -2
y = mx + b
m = slope
b = y-intercept
y = 3/4x - 2
Use Lagrange multipliers to find the maximum and minimum values of subject to the given constraint. Also, find the points at which these extreme values occur.
f(x, y) xy: 48x+3y2 3456
Enter your answers for the points in order of increasing x-value.
Maximum______
Minimum_______
Answer:
Following are the responses to the given question:
Step-by-step explanation:
Given:
[tex]\to f(x,y)=xy\\\\\to 48x^2+3y^2=3456\\\\[/tex]
let [tex]\phi(x,y)=48x^2+3y^2=3456[/tex]
using the lagrange multiplies:
[tex]\bigtriangledown f=\lambda \bigtriangledown \phi\\\\i)\ \ y=96 \lambda x \to \lambda=\frac{y}{96\ x} \\\\ii)\ \ x=6 \lambda y \to \lambda=\frac{y}{6\ y} \\\\iii)\ \ 48x^2+3y^2=3456\\\\[/tex]
From equation (i) and (ii)\\\\
[tex]\to \frac{y}{96x}=\frac{x}{6y}\\\\\to 6y^2=96x^2\\\\\to 3y^2=48x^2\\\\[/tex]
From equation 3:
[tex]48x^2+48x^2=3456\\\\96x^2 3456\\\\x^2=36\\\\x=\pm 6\\\\\therefore 3y^2=48(36)\\\\3y^2=1728\\\\y^2=576\\\\y=\pm24\\\\(x,y)=(\pm 6,\pm 24)\\\\Maximum \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 144 \ \ \ \ at \ \ (6,24) \ \ \ \ \ \ \ and \ \ \ \ \ \ (-6, -24) \\\\Minimum \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ -144 \ \ \ \ at \ \ (-6,24) \ \ \ \ \ \ \ and \ \ \ \ \ \ (6,-24)\\\\[/tex]

Step-by-step explanation:
Cos Y=?
5/13
5/12
12/13
Answer:
Cos Y = 12/13
Step-by-step explanation:
Recall, SOHCAHTOA.
Cos Y = Adjacent/Hypotenuse
Reference angle = Y
Adjacent = 12
Hypotenuse = 13
Therefore:
Cos Y = 12/13

Explain a method you could use to find 50% out of $24.
Answer:
$12
Step-by-step explanation:
50% means half of something. Like 50% of 20 is 10. 100% means the whole number. So, 50% is half of the number.
24 divided by 2 is 12.

Which of the following would be a correct interpretation of a 99% confidence interval such as 4.15.6? Choose the correct answer below. A. We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of . B. It means that 99% of sample means fall between 4.1 and 5.6. C. It means that 99% of all data values are between 4.1 and 5.6. D. There is a 99% chance that will fall between 4.1 and 5.6.
Answer:
A. We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of population mean.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
99% confidence interval means that we are 99% sure that this interval contains the population mean.
Interval between 4.1 and 5.6.
So the correct answer is given by option A.
Help me ASAP plzzzz I’m struggling on this one rlly badly
Answer:
y = -2x + 5
Step-by-step explanation:
Points on the path: (0, 5) and (1, 3)
Slope:
m=(y2-y1)/(x2-x1)
m=(3-5)/(1-0)
m= (-2)/1
m= -2
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = -2(x - 0)
y - 5 = -2x
y = -2x + 5

Which equation is NOT equivalent to p – 7 = 22? Select all that apply.
A. p – p – 7 = 22 – p
B. p – 7 – p = 22 – p
C. p – 7 + 22 = 22 – 7
D. p – 7 + 7 = 22 – 22
E. p – 7 + 7 = 22 + 7
Answer:
C. p - 7 + 22 = 22 - 7
D. p - 7 + 7 = 22 - 22
Step-by-step explanation:
p - 7 = 22
Add 7 to both sides
p = 29
An equivalent equation could be;
-7 = 22 - p

If a circle has a circumference of 8.5 cm, what is the diameter of the circle to the nearest 0.1 cm?
Answer:
Step-by-step explanation:
2[tex]\pi[/tex]r = circumference
2[tex]\pi[/tex]r = 8.5 cm
[tex]\pi[/tex]r = 4.25 cm
r = 1.352817 cm
d = 2r
d= 2.705
diameter = 2.7 cm
