ong>Answer:

This IMPLIES that

x2+2ax=4x−4a−13

or

x2+2ax−4x+4a+13=0

or

x2+(2a−4)x+(4a+13)=0

Since the equation has just ONE SOLUTION instead of the USUAL two distinct solutions, then the two solutions must be same i.e. discriminant = 0.

Hence we get that

(2a−4)2=4⋅1⋅(4a+13)

or

4a2−16a+16=16a+52

or

4a2−32a−36=0

or

a2−8a−9=0

or

(a−9)(a+1)=0

So the values of a are −1 and 9.

ong>Answer:

60 m , 40 m

Step-by-step explanation:

let, the breadth of the FIELD is X

so, the length is 1.5x

total length of WHITE line will be =2(x+1.5x) = 5x

so, 5x= 200

►x = 40

length = 1.5×40 = 60 m

breadth = 40 m

ong>Given :- A 56.8 kg CONCRETE slab can be balanced by two concrete pillars, each WEIGHING 41.3 kg. How many concrete pillars are needed to SUPPORT slabs that weigh 681.6 kg ? Calculate the total weight of the slabs and the pillars. ?

Solution :-

we have given that, A 56.8 kg concrete slab can be balanced by two concrete pillars.

we can say that,

→ 56.8 kg concrete slab can be balanced by = 2 pillar.

So,

→ 1 kg concrete slab can be balanced by = (2/56.8) Pillars.

Than,

→ 681.6kg concrete slab can be balanced by = (2 * 681.6) / (56.8) = 24 Pillar. (Ans.)

Now, we have given that,

→ weight of 1 Pi|lar = 41.3 kg.

So,

→ weight of 24 Pillars = 41.3 * 24 = 991.2 kg.

Therefore,

→ Total weight of slab and the pillars = 681.6 + 991.2 = 1672.8 kg .(Ans.)

ong>Answer:

60 DEGREES

Step-by-step explanation:

Both triangles are SIMILAR triangles

Therefore angle QPR = angle BAC

3x = 2x+20

x = 20

3x = 60

Sum of angles in a TRIANGLE is 180 degrees

So, 180-60-60=60 degrees

Therefore, MEASURE of required angle is 60 degrees.

★ Gɪᴠᴇɴ :-

• Initial velocity = 20 m/s
• Comes rest after 2 seconds

__________________________

★ Tᴏ Fɪɴᴅ :-

• ACCELERATION acquired

__________________________

★ Sᴏʟᴜᴛɪᴏɴ :-

Finding acceleration acquired using FIRST EQUATION of motion.

v = u + at

Where,

• v → final Velocity = 0 m/s
• a → acceleration = ?
• u → initial velocity = 20 m/s
• t → time taken = 2 s

Note :- Here , the final velocity ( v ) will be zero because the boday comes rest after two second . So , final velocity ( v ) = 0 m/s.

Substituting the values we have,

⇒ 0 = 20 + a(2)

⇒ - 20 = 2a

⇒ a = -20 ÷ 2

⇒ a = - 10 m/s²

Note :- Negative symbol SHOW that the BODY has retardation.

Hence , acceleration of the body is - 10 m/s²
