X^2/16 + y^2/25 =1 The length of the major axis is: 5 10 25

Mathematics

Answer:

Major axis length = 10

Step-by-step explanation:

Given:

The equation given is:

\frac{x^2}{16}+\frac{y^2}{25}=1

The above equation represents a standard ellipse of the form:

\frac{x^2}{a^2}+\frac{y^2}{b^2}=1

If a > b then 'a' is the semi-major axis length and 'b' is the semi-minor axis length.

If a < b, then 'a' is the semi-minor axis length and 'b' is the semi-major axis length.

On comparing the given equation with the standard form, we get:

a^2=16\\a=\sqrt{16}=4\\\\b^2=25\\b=\sqrt{25}=5

Here, b > a as 5 > 4. So, the length of major axis is twice the length of 'b' and is equal to:

Major axis length = 2\times b=2\times 5 =10

Find the theoretical probability of rolling a number cube labeled 1-12 and<br> it landing on 7.
Rashid [163]

Answer:

1/12

Step-by-step explanation:

There are 12 sides, and 7 is one of them. Therefore, there is a 1/12 chance of it landing on that side if it is a fair cube.

Suppose 2 eggs with bacon cost 2.70 . One egg with bacon costs 1.80 . At thesebrates what will bacon alone cost
Leno4ka [110]

If 2 eggs with bacon cost 2.70, and 1 egg with bacon costs 1.80, that means that 1 egg costs 0.90, so when we subtract once more 0.90 we get the price of the bacon alone, which is in this case 0.90.

Identify the three similar right triangles in the given diagram.
irga5000 [103]

Answer:

B. ΔABD, ΔADC, ΔDBC

Step-by-step explanation

Step -1 In ΔABD and ΔADC (from figure).

∠DAB=∠CAD (common in both triangles) ,

∠DBA=∠CDA =90 degree, and

∠BDA=∠DCA (rest angle of the two triangles).

therefore ΔABD similar to ΔADC (by AAA similarity theorem).

Step -2 In ΔDBC and ΔADC (from figure).

∠DCB=∠ACD (common in both triangles) ,

∠DBC=∠ADC =90 degree, and

∠CDB=∠CAD (rest angle of the two triangles).

therefore ΔDBC similar to ΔADC (by AAA similarity theorem).

Step -3 In ΔABD and ΔDBC (from figure).

∠BDA=∠BCD (because , ∠ACD=ADB from stap-1 and ∠ACD=∠BCD from figure) ,

∠DBA=∠CBD =90 degree, and

∠BAC=∠BDC (rest angle of the two triangles).

therefore ΔABD similar to ΔDBC (by AAA similarity theorem).

In the above step- ΔABD similar to ΔADC, ΔDBC similar to ΔADC and ΔABD similar to ΔDBC.

Hence ΔABD, ΔADC, ΔDBC similar to each other in the given figure.
