If x2 + y2 + z2 = 9, dx dt = 3, and dy dt = 9, find dz dt?
Answers
Answer:
dz/dt = -(3x + 9y)/z
Step-by-step explanation:
x² + y² + z² = 9
2x dx/dt + 2y dy/dt + 2z dz/dt = 0
x dx/dt + y dy/dt + z dz/dt = 0
x * 3 + y * 9 + z dz/dt = 0
so
dz/dt = -(3x + 9y)/z

The length of a rectangle is 6 inches more than the width. If the perimeter is 68 inches, what are the length and the width?
Answers
W= width
L= 6+w
P= 2(L + W)
68= 2(L+ W)
L+w= 34
(6+w) + w= 34
6 + 2w = 34
2w= 28
W= 14
L= 14+6 = 20
L= 20 AND W=14
Answer: The length of the rectangle would be 20 inches and the width would be 14 inches.
Step-by-step explanation:
If the length is 20, first, it’s 6 more than 14, and second it would add up to 40. If the width is 14, it’s 6 less than 20, and adds up to 28. If you add those two together, you’d get your total of 68 inches for the perimeter!

IF Cos 3A =Sin7A then A is
Answers
Answer: A=0.8767601914
First you need to find the value of cos(3) and sin(7) which happens to be cos(3)=0.9986295348A and sin(7)=0.1218693434A. So you have the numbers, then what do you do with them? Well you will want to subtract them both and find the difference between them which should be the value of A. so 0.9986295348-0.1218693434=0.8767601914 so A=0.8767601914 if you want you can simplify this...

The table shows the number of gallons of gas used and the number of miles driven. Gallons of Gas Used 12 15 18 12 14 16 Miles Driven 300 400 450 350 400 450 Is the resulting data set a function? Explain your reasoning. A The table is a function. The function can have more than one input value paired with the same output value. B The table is a function. The function can have more than one output value paired with the same input value. C The table is not a function. The function cannot have different input values paired with the same output value. D The table is not a function. The function cannot have the same input value paired with different output values.
Answers
There is one input being mapped into two different outputs, so this is not a function. The correct option is D.
What is a function?A function is a relation that maps elements from one set (the domain) into elements from another set (the range). Such that each element from the domain can be mapped into only one element from the range.
In this case, the table is:
Gallons of Gas Used: 12 15 18 12 14 16Miles Driven: 300 400 450 350 400 450So, the input "12" appears twice, the first time is mapped into 300 miles, and the second time is mapped into 350.
So the same value from the domain is being mapped into two different values of the range, meaning that this is not a function. So the correct option is D.

Hope this helps!
The first step is to find any two sets of points on the line to find the slope. Let's use (0, -6) and (4,10).
[tex]Slope=\frac{y2-y1}{x2-x1} =\frac{10--6}{4-0} =\frac{16}{4} =4[/tex]
Ok, now we found the slope. Now let's put it into the point-slope form which requires any one point on the line and the slope. Lets use the point (0,-6)
[tex](y-y0)=m(x-x0)\\(y+6)=4(x-0)\\y=4x-6[/tex]
The last equation is the slope-intercept form.

Two cars leave New York at the same time traveling in opposite directions. One travels at an average speed of 59mph and the other at 58mph. In how many hours will they be 468 miles apart?
Answers
Answer: In 4 HOURS they will be 468 miles apart.
Step-by-step explanation:
1st car DATA:
rate = 59 mph ; time = x hrs. ; distance = 59x miles
2nd car DATA:
rate = 58 mph ; time = x hrs. ; distance = 58x miles
EQUATION:
distance + distance = 385
59x + 58x = 468
117x = 468
x = 4 hours.

120° = 2(x)°
120/2 = x
60 = x
Step-by-step explanation:
120° = 2(x)° because the two lines cross forming an x shape and angles opposite to each other are always equal in lines forming x shapes. Hence you can form an equation as shown above and solve it for x. Since the above equation is a linear one you can simply solve it by bringing all the numbers to one side. since 2 is multiplied on the right hand side, when we bring it to the left it has to be divided.

Marie built her sand castle? Explain
how you found your answer.
Answers
Answer:
Are there any measurements for the size of the prisms? I think we need more info for this. I'll delete this when you answer and upload a new one :)
Step-by-step explanation:
The amount of sand left after building the sand castle is 290 inches³.
What is Rectangular Prism?Rectangular prism is a three dimensional shape which consist of six faces. The two faces are at the top and bottom and the other faces are lateral faces.
We have to find the volume of each of the rectangular prism to know how much sand is used to make the castle.
Volume of a rectangular prism = l × w × h
where l, h and w are length, height and width of the prism respectively.
Volume of larger prism = 15 × 15 × 6
= 1350 inches³
Volume of smaller prism = 9 × 8 × 5
= 360 inches³
Total volume of the castle = 1350 + 360 = 1710 inches³
Remaining sand = 2000 - 1710 = 290 inches³
Hence the sand that remains is 290 inches³.
