Yes,there is 7 days in a week,so you can multiply 7 days by 7 weeks..So 7*7=49.
So 49 days is less than 52 days.

Every 4 seconds, a ski lift chair rises 14 feet. Describe the relationship between the height of the chair and the time.

Answers

The relationship between the rise of the chair with respect to time is required.

The ski lift chair rises $3.5\ \text{feet/s}$

Rate of change

Every $4$ seconds a ski lift chair rises $14\ \text{feet}$ .

$4\ \text{seconds}=14\ \text{feet}$

Divide by $4$ on both sides

$1\ \text{second}=(14)/(4)=3.5\ \text{feet}$

The rate of the height increase of the ski lift chair is $3.5\ \text{feet/s}$

Find an equation in standard form for the ellipse with the vertical major axis of length 18 and minor axis of length 16.

Answers

Answer:

x²/64 + y²/81 = 1

Step-by-step explanation:

Standard form of an equation for the ellipse is $(x^(2) )/(a^(2))+(y^(2) )/(b^(2) )=1$

Here b is the length of vertical major axis = 9

and minor axis of length a = 8

Therefore the equation of the ellipse will be

$(x^(2) )/(8^(2) )+(y^(2) )/(9^(2) ) =1$

$(x^(2) )/(64)+(y^(2) )/(81)=1$

So the answer is x²/64 + y²/81 = 1

Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2

What is the slope between 3,6 and 11,6

Answers

Answer:

slope = 0

Step-by-step explanation:

calculate the slope m using the slope formula

m = $(y_(2)-y_(1) )/(x_(2)-x_(1) )$

let (x₁, y₁ ) = (3, 6 ) and (x₂, y₂ ) = (11, 6 )

substitute these values into the formula for m

m = $(6-6)/(11-3)$ = $(0)/(8)$ = 0

What is the solution to this system of linear equations?

x + y = 4

x − y = 6

Answers

Answer:

x=5 , y= -1

Step-by-step explanation:

You can see that one of the y's is negative while the other is positive, so you can add them together.

Now, negative 1 + positive 1 = 0, so the y's cancel out leaving only the x's.

Remember you can't add one part without adding the other so x+x = 2x, and 4+6=10. This makes the final equation 2x=10.

You can simplify that into x=5. This gives you the answer for x

Then substitute x=5 into any of the two equations (doesn't matter) I'll use the first one. So if you substitute it you get 5+y=4.

Simplified, y= -1

Therefore, x= 5 and y=-1
