Find an equation in standard form for the ellipse with the vertical major axis of length 6 and minor axis of length 4

Answers

Answer:

  x^2/4 +y^2/9 = 1

Step-by-step explanation:

The standard form is ...

  (x -h)^2/a^2 +(y -k)^2/b^2 = 1

for an ellipse centered at (h, k) with semi-axis measures "a" and "b". The largest of "a" or "b" is the semi-major axis; the smaller, the semi-minor axis.

Here, the major axis is vertical, so b > a.

Since the center is not given, we assume it is the origin: h = k = 0. The semi-axes are a=2, b=3, so the equation is ...

  x^2/4 +y^2/9 = 1

What is the length of AC ? Round to the nearest tenth.10.5 m
12.3 m
18.3 m
21.4 m

Answers

The length of AC is equal to 10.5m

Data;

  • AC = ?
  • BC = 15m
  • Angle = 55 degrees

Trigonometric Ratio

To solve this problem, we have to apply trigonometric ratioSOHCAHTOA here;

Since we have the value of opposite side, angle and we are looking for the adjacent, we can use tangent of the angle to find AC
tan\theta = (opposite)/(adjacent)

Let's substitute the values and solve for AC

tan 55 = (15)/(AC) \nAC = (`15)/(tan55) \nAC = 10.5m

From the calculations above, the length of AC is equal to 10.5m

In this right triangle, side AC is adjacent to the reference angle we were given.  That's our unknown.  The other side is the side opposite the reference angle, so we need a trig ratio that relates the side adjacent to the side opposite which is tangent.  Setting up our ratio we have this: tan(55)= (15)/(x) and x= (15)/(tan(55)).  Do that on your calculator to find that side AC (x) = 10.5, first choice above.

A line is drawn through (–4, 3) and (4, 3). Which describes whether or not the line represents a direct variation?

Answers

The line does not represent a direct variation because it does not go through the origin.

1Step-by-step explanation:

A customer buys $17.01 of gas and request one $5 lottery ticket, two $1 lottery ticket and one $3 lottery tickets he gives you two winning tickets to redeem one for $5 and the other for $2. How much change what you receive from $100 bill.

Answers

So first add $5 and $2 to $100 so you have 107 dollars.

Then add 17.01 + 5 + 1 + 1 + 3 = 28.01. so then do 107 - 28.01 = $78.99
