Answer:

492.87cm^3

Step-by-step explanation:

Given data

Diameter= 4.9cm

The expression for the volume is

V= 4/3 πr^3

Substitute

V= 4/3*3.142*4.9^3

V= 4/3*3.142*117.649

V=1478.612632 /3

V=492.87 cm^3

Hence the volume is 492.87cm^3

In quadrilateral ABCD, BN and DM are drawn perpendicular to AC such that BN = DM. Prove that O is the midpoint of BD
GaryK [48]

Answer:

Step-by-step explanation:

Given :

In the given quadrilateral ABCD,

BN and DM are the perpendiculars drawn to AC such that,

BN = DM

To prove:

Point O is the midpoint of segment BD.

Or

OD = OB

Solution:

In ΔOMD and ΔONB,

∠MOD ≅ NOB [Vertical angles]

∠M ≅ ∠N ≅ 90° [Given]

Therefore, by AA property of similarity,

ΔOMD ~ Δ ONB

Therefore, their corresponding sides will be proportional,

\frac{DM}{BN}=\frac{OD}{OB}

Since BN = DM,

OD = OB

Hence O is the midpoint of BD.

Without solving determine the character of the solutions of the equation x^2+2x+5=0
Sav [38]
★ QUADRATIC RESOLUTION ★

Roots of the given equation will be imaginary because it's discriminant is less than 0 and hence it'll yield imaginary solutions

D < 0

b² - 4ac < 0

4² - 4 ( 5 ) < 0

16 - 20 < 0

-4 < 0

Hence it's character is stated above

Step-by-step explanation please ​
Korvikt [17]

Answer:

C : 4.29

Step-by-step explanation:

First find the distance she walks on the weekdays.

0.55*5=2.75

Now you find out how much she walks on one weekend and multiply that by two.(Saturday and Sunday)

0.55*1.4=0.77

0.77*2=1.54

Now add the two numbers

1.54+2.75=4.29

Hope I helped!!!

Have a great day!
