divide 56 into four parts which are the four terms of an AP such that the product of the first and the fourth terms is to the product of the second and the third terms as 5:6

Answer»

4 no =a-3d,a-d,a+d,a+3d

sum , 4a=56

a=14

(a-3d)(a+3d)/(a-d)(a+d)=5:6

6(a²-9d²)=5(a²-d²)

a²=54d² - 5d²

14² =49d²

d²=14² /7²

d=±14/7=±2

for d=2,

a-3d=14-6=8

a-d=14-2=12

a+d=14+2=16

a+3d=14+6=20

Numbers are 8,12,16,20

On dividing polynomial 2x³+ax²+3x-5 by x-1 , the remainder is 7.Find the value of a.

Answer»

Here is your SOLUTION,

x-1 = 0

x = 1

p(x) = 2x³ + ax² + 3x - 5

p(1) = 2×(1)³ + a×(1)² + 3×1 - 5

= 2×1 + a + 3 - 5

= 2+a+3-5

= 0 + a =7

a = 7-0

a = 7

So, the value of a is 7

Answer»

Hello here is your answer by SUJEET YADUVANSHI ☝☝☝☝☝☝☝☝☝☝☝☝☝☝☝☝



Let to be 10' unit digit=x
Let to be 1 unit digit=y
then,

X+y=10. ----(1)


Again,


10x+y+54=10y+x

10x-x+y-10y=-54
9x-9y=-54

9(x-y)=-54

x-y=-54/9
x-y=-6


Now solving the equation by elimination METHOD:))


x+y=10
x-y=-6

_______
2y=16

y=16/2
y=8


then,

x+y=10
x+8=10
x=10-8
x=2

Again Required Number:).


10y+x

10*8+2
80+2

On dividing polinomial 2x³+ax²+3x-5 by x-1 , the remainder is 7.Find the value of a.

Answer»

Here is your solution,

X-1 = 0

x = 1

p(x) = 2x³ + ax² + 3X - 5

p(1) = 2×(1)³ + a×(1)² + 3×1 - 5

= 2×1 + a + 3 - 5

= 2+a+3-5

= 0 + a =7

a = 7-0

a = 7

So, the value of a is 7

Find the HCF of a) 105,570

Answer»

Find the prime factorization of 105
105 = 3 × 5 × 7

Find the prime factorization of 570
570 = 2 × 3 × 5 × 19

To find the gcf, multiply all the prime FACTORS common to both numbers:

THEREFORE, GCF = 3 × 5

GCF = 15

The greatest common factor (gcf) is also known as greatest common DIVISOR (gcd) or highest common factor (hcf).

Pls ans to be brainlist

Answer»

Let the present ages of father and son be 'x' and 'y' respectively.

Given that, x + y = 45
So, x = 45-y

5 years ago,
Father's age = x-5
Son's age = y-5

Given, (x-5)(y-5) = 124

(45-y-5)(y-5) = 124

(40-y)(y-5) = 124

40y - 200 - y^2 + 5y = 124

y^2 - 45Y + 324 = 0

Solving the above quadratic equation, we get

We get y = 9
So x = 36

Thus, the present age of son is 9 years and the present age of father is 36 years .

If a b c are positive and a+b+c=1 then the least value of 1/a+1/b+1/c is

Answer»

Assuming that a, B, c are positive.

It is a well KNOW fact that A.M≥H.M.A.M≥H.M.

Applying this to a,b,ca,b,c

a+b+c3≥3(1a+1b+1c)a+b+c3≥3(1a+1b+1c)

CROSS multiplying gives that

(a+b+c)(1a+1b+1c)≥9(a+b+c)(1a+1b+1c)≥9

Thus, the minimum value is 99, when a=b=c=1

Find the area of quadrilateral abcd ,has ab=3cm,bc=4cm,cd=4cm,da=5cmand,ac=5cm

Answer» AB = 3cm
bc = 4cm
cd = 4cm
ad = 5cm
ac = 5cm
Pythagoras theorem says c^2 = a^2 + b^2
c = ac = 5cm
a = ab = 3cm
b = bc = 4cm
c^2 = (5cm)^2
a^2 = (3cm)^2
b^2 = (4cm)^2
25 = 9 + 16
So it is a right angle.
A = (b×h)/2
A = (3×4)/2 = 12/2 = 6cm
abc = 6cm
A of TRIANGLE = √s(s-a)(s-b)(s-c)
s = (a+b+c)/2
s = (5+5+4)/2 = 14/2 = 7
√7(7-5)(7-5)(7-4)
√7×2^2×3
2√21cm
6+2√21cm
8√21cm

Check whether the following statements are true or not.1. a+b=d+c2. a+c+e=180°b+f=c+e

Answer»

Hey
1 ) True as Angle d and angle a are equal so we can put value of d as a. (VERTICALLY opposite angles)

2) YES it is also true as we can put angle d at PLACE of angle a and angles d, c,e form a LINE.

3) False as angle b + c = f + e ( Vertically opposite angles) .
THEREFORE, b-f = e - c.
