Given:
Image of the ellipse
To find:
The equation of the image
Solution:
The given image is a ellipse.
Center of the ellipse = (0, 0)
x-axis points are (-3, 0) and (3, 0).
y-axis points are (2, 0) and (-2, 0).
Standard form of equation of ellipse:
where (h, k) is the center = (0,0)
a is the point on x-axis where y = 0. Hence a = 3.
b is the point on y-axis where x = 0. Hence b = 2.
Substitute this in the standard form of ellipse.
To make the denominator same multiply 1st term by 
and 2nd term by 
.
Multiply by 36 on both sides
The equation of the image is .
Answer:
A
Step-by-step explanation:
125 = 5 * 5 * 5 = 5³
90 = 2 * 3 * 3 * 5 = 2 * 3² * 5
92 = 2 * 2 * 23 = 2² * 23
Answer:
80000
Step-by-step explanation:
Significant figures are any number but zeroes.
However, in some cases, zeroes also count as significant figures.
- Zeroes are significant figures when between other non-zero numbers.
- Zeroes are significant when you see a dot on the right indicating that zero is not a place holder.
- They are <u>not</u> significant when serving as place holders, such as zeroes on the right side of a number. For example, .004 has 1 sig fig. The 2 zeroes on the left aren't sig figs because they're just place holders.
- Zeroes on the <u>right</u> side of a decimal are also significant.
