Answer» Answer: Let the initial velocity of the body be U m/s; and the constsnt acceleration be a m/s². Then DISPLACEMET (distance covered) of the body after t second is given by s = u t + ½ a t² ———————————-(1) The body covers 20 m in 2s and 80 m in 4 s. 20 = u×2 + ½ a 2²; => 20 = 2 u + 2 a u + a = 10 —————————————(2) 80 = u×4 + ½ a 4²; => 80 = 4 u + 8 a; this gives, u + 2 a = 20 ——————————————(3) Solving (2) and (3) for u and a we get u = 0 m/s and a = 10 m/s² ————————(4) To obtain the distance covered in the NEXT 4s we need to find the velocity at the beginning of this interval using, V = u + a t => v = 0 m/s + 1.....

Two events, A and B, are independent of each other. P(A)= and P(A and B)=. What is P(B) written as a decimal? Round to the nearest hundredth, if necessary.0.020.040.290.75

Answer»

Answer:

Let the initial velocity of the body be U m/s; and the constsnt acceleration be a m/s². Then DISPLACEMET (distance covered) of the body after t second is given by

s = u t + ½ a t² ———————————-(1)

The body covers 20 m in 2s and 80 m in 4 s.

20 = u×2 + ½ a 2²; => 20 = 2 u + 2 a

u + a = 10 —————————————(2)

80 = u×4 + ½ a 4²; => 80 = 4 u + 8 a; this gives,

u + 2 a = 20 ——————————————(3)

Solving (2) and (3) for u and a we get

u = 0 m/s and a = 10 m/s² ————————(4)

To obtain the distance covered in the NEXT 4s we need to find the velocity at the beginning of this interval using,

V = u + a t => v = 0 m/s + 1.....

Correct option is D ) 2160 in².

Explanation →

Given ,

No. of TILES required to make a tabletop by Mateo = 60 tiles.
Length of the side of square shaped tile ( say "a" ) = 6 inch.

So,

Using the formula for area of square we can CALCULATE the area of one tile.
Area = a² = 6² = 36 inch²

As , The no. of tiles = 60

So , area of tabletop will be = no. of tiles x area of one tile
= 60 x 36 inch²

Answer»

Given : The high school stadium contains a track that surrounds a soccer field. The soccer field is 100 YARDS long and 70 yards wide.

The school decided to cover the semicircles with GRASS to create a space for stretching and other activities.

To Find: area of one of the semicircles at either END of the track

How many square yards of grass will the school need to cover the entire circle?

Solution:

Diameter of SEMICIRCLE = 70 yards

Radius of semicircle = 70/2 = 35 yards

Area of semicircle at one end = (1/2)πr²

= (1/2)(22/7)35²

= 1,925 sq yards

area of one of the semicircles at either end of the track = 1,925 sq yards

square yards of grass will the school need to cover the entire circle

= 2 x 1,925

= 3850 sq yards

distance around one of the semicircles at either end of the soccer field = πr = (22/7) 35 = 110 yards

distance around the inner lane of the track = 100 + 100 + 110 + 110

= 420 yards

37.	the ratio of present age of asha and lata is 5:6 if the difference between there age is 6 then what is the age of asha after 5 year
Answer» Answer: 35 year. Step-by-step explanation: Given, ratio of PRESENT age of Asha and Lata is 5 : 6. LET the present age of Asha be 5a and Lata be 6a. According to the question : ⇒ DIFFERENCE between the ages of asha and lata is 6 ⇒ Age of Lata - age of Asha = 6 ⇒ 6a - 5a = 6 ⇒ a = 6 Hence, Present age of Asha is 5a = 5( 6 ) YEARS = 30 year. After 5 year she will be 5 year older than present, her age will be 30 year + 5 year = 35 year

37.

the ratio of present age of asha and lata is 5:6 if the difference between there age is 6 then what is the age of asha after 5 year

Answer»

Answer:

35 year.

Step-by-step explanation:

Given,

ratio of PRESENT age of Asha and Lata is 5 : 6.

LET the present age of Asha be 5a and Lata be 6a.

According to the question :

⇒ DIFFERENCE between the ages of asha and lata is 6

⇒ Age of Lata - age of Asha = 6

⇒ 6a - 5a = 6

⇒ a = 6

Hence,

Present age of Asha is 5a = 5( 6 ) YEARS = 30 year.

After 5 year she will be 5 year older than present, her age will be 30 year + 5 year = 35 year

Answer» SHORTER PIECE is 10 foot long. Length of the wooden board = 30 foot After cutting the wooden board into two pieces , with a ratio of 2 : 4 , Say Length of 1st piece = 2x Length of 2ND piece = 4x According to the question , 2x + 4x = 30 foot 6x = 30 X = 30 ÷ 6 x = 5 So, Length of the small piece = length of the 1st piece = 2x = 2 x 5 = 10 foot And the length of the 2nd piece = 4x = 4 x 5 = 20 foot

Andrew cut a 30-foot long wooden board into 2 pieces. The ratio of the length of the two pieces is 2:4. What is the length of the shorter piece of wood

Answer»

SHORTER PIECE is 10 foot long.

Length of the wooden board = 30 foot

After cutting the wooden board into two pieces , with a ratio of 2 : 4 , Say

Length of 1st piece = 2x
Length of 2ND piece = 4x

According to the question ,

2x + 4x = 30 foot
6x = 30
X = 30 ÷ 6
x = 5

So,

Length of the small piece = length of the 1st piece = 2x = 2 x 5 = 10 foot
And the length of the 2nd piece = 4x = 4 x 5 = 20 foot

Answer»

Answer:

1716

Step-by-step explanation:

the formula for COMBINATION is

nCr = N! / r! × (n-r) !

13C6 = 13 ! / 6! × (13-6)!

= 13! / 6! × 7!

= 13 × 12 × 11 × 10 × 9 × 8 × 7! / 6! × 7!

= 13 × 12 × 11 × 10 × 9 × 8 / 6 × 5 × 4 × 3 × 2 × 1

= 1716

49.	The function f(x)=(x-1) \|x^2-3x + 2\| +cosx(x). is not differentiable at **
Answer» Given: The correct function is f(x)=(x²-1) mod( x² - 3x + 2 ) +cos mod( x ) To find: The given function is not differential at? Solution: Now lets WRITE the given function: f(x)=(x²-1) mod( x² - 3x + 2 ) + cos mod( x ) So now, let us consider two FUNCTIONS: G(x) and H(x) g(x) = (x²-1) mod( x² - 3x + 2 ) h(x) = cos mod( x ) So eventually h(x) becomes: h(x) = g(x) + h(x) Now consider the function h(x) = cos mod( x ) As we know that mod(x) is x when x≥0 and -x when x<0 So cos mod(x) will be cos x when x≥0 and cos(-x) when x<0 But we know that cos(-x) = cos x, so it becomes cos x ∈ R. As the graph of cos x do not have any SHARP point so it is always differentiable. Now lets consider g(x) = (x²-1) mod( x² - 3x + 2 ) Solving this, g(x) = (x-1)(x+1) mod((x-1)(x-2)) g(x) = (x-1)(x+1) mod(x-1)mod(x-2) So the critical points are: 1, -1, 2 When x≤-1, g(x) will be positive. When -1 When 1 When x>2, g(x) will be positive. So we can see that graph is not changing in third and fourth case, so the function is not differentiable at 2. Answer: So the function is not differentiable at 2.

The function f(x)=(x-1) |x^2-3x + 2| +cosx(x). is not differentiable at **

Answer»

Given: The correct function is f(x)=(x²-1) mod( x² - 3x + 2 ) +cos mod( x )

To find: The given function is not differential at?

Solution:

Now lets WRITE the given function:

f(x)=(x²-1) mod( x² - 3x + 2 ) + cos mod( x )

So now, let us consider two FUNCTIONS: G(x) and H(x)

g(x) = (x²-1) mod( x² - 3x + 2 )

h(x) = cos mod( x )

So eventually h(x) becomes:

h(x) = g(x) + h(x)

Now consider the function h(x) = cos mod( x )

As we know that mod(x) is x when x≥0 and -x when x<0

So cos mod(x) will be cos x when x≥0 and cos(-x) when x<0

But we know that cos(-x) = cos x,

so it becomes cos x ∈ R. As the graph of cos x do not have any SHARP point so it is always differentiable.

Now lets consider g(x) = (x²-1) mod( x² - 3x + 2 )

Solving this,

g(x) = (x-1)(x+1) mod((x-1)(x-2))

g(x) = (x-1)(x+1) mod(x-1)mod(x-2)

So the critical points are: 1, -1, 2

When x≤-1, g(x) will be positive.

When -1

When 1

When x>2, g(x) will be positive.

So we can see that graph is not changing in third and fourth case, so the function is not differentiable at 2.

Answer:

So the function is not differentiable at 2.
