Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC . What is the leng

Thepotemich [5.8K]

Answer:

Length of side of rhombus is $x=\frac{ab}{a+b}$

Step-by-step explanation:

Given Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC. We have to find the length of side of rhombus.

It is also given that AB=a and AC=b

Let side of rhombus is x.

In ΔCEF and ΔCBA

∠CEF=∠CBA (∵Corresponding angles)

∠CFE=∠CAB (∵Corresponding angles)

By AA similarity rule, ΔCEF~ΔCBA

∴ their sides are in proportion

$\frac{EF}{AB}=\frac{CF}{AC}$

⇒ $\frac{x}{a}=\frac{b-x}{b}$

⇒ $xb=ab-ax$

⇒ $x(a+b)=ab$

⇒ $x=\frac{ab}{a+b}$

Hence, length of side of rhombus is $x=\frac{ab}{a+b}$

A plane flies with an average velocity of -98.5 m/s for 45.0s .What is the displacement?

Gnesinka [82]

Answer:

-4432.5 m

Step-by-step explanation:

Displacement is measured in meters, so will be the product of velocity in m/s and time in s.

(-98.5 m/s)×(45.0 s) = -4432.5 m

___

If you're concerned with significant figures, you can round this to -4430 m, which has the required 3 significant figures.

Write the first four terms of the sequence defined by An=20-30(n-1)

monitta

The first four terms of sequence is 20, -10, -40, -70

Solution:

Given that we have to find the first four terms of sequence

Given recursive formula is:

$a_n = 20 - 30(n-1)$

To find the first term, substitute n = 1

$a_1 = 20-30(1-1)\\\\a_1 = 20-30(0)\\\\a_1 = 20$

Thus the first term of sequence is 20

To find the second term, substitute n = 2

$a_2 = 20-30(2-1)\\\\a_2 = 20-30(1)\\\\a_2 = 20-30\\\\a_2 = -10$

Thus the second term of sequence is -10

To find the third term, substitute n = 3

$a_3 = 20-30(3-1)\\\\a_3 = 20-30(2)\\\\a_3 = 20-60\\\\a_3 = -40$

Thus the third term of sequence is -40

To find the fourth term, substitute n = 4

$a_4 = 20-30(4-1)\\\\a_4 = 20-30(3)\\\\a_4 = 20-90\\\\a_4 = -70$

Thus the first four terms of sequence is 20, -10, -40, -70
