2.

Find the number of non-prime factors of 4^10 x 7^3 x 5^9.

Answer»

Answer:

2^5*3^7*3^4*11^4*13^3

2^5*3^11*11^4*13^3

Number of FACTORS: (5+1)(11+1)(4+1)(3+1)=6*12*5*4=1440

The only PRIME factors are 2, 3, 11, and 13. All other factors are not prime.

Therefore, there are 1440–4 = 1436 NON prime factors.

1.The product of a non-zero number and an irrational number is: (A) always irrational (B) always rational (C) rational or irrational (D) one

Answer»

Answer:

ALWAYS irrational

Step-by-step EXPLANATION:

Non zeroes rational NUMBERS are 1,2,3,4,5....

Irrational NUMBER are √2,√3,√5,√6...

1×√2 = √2

2×√2 = 2 √2

4×√3 = 4√3

all results are irrational numbers .

THEREFORE, the product of an non zeroes rational number with an irrational number is always irrational

Additional Information:-

RELATIONSHIP between sides and T ratios

sin θ = Opposite Side/Hypotenuse

cos θ = Adjacent Side/Hypotenuse

tan θ = Opposite Side/Adjacent Side

sec θ = Hypotenuse/Adjacent Side

cosec θ = Hypotenuse/Opposite Side

COT θ = Adjacent Side/Opposite Side

Reciprocal Identities

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

sin θ = 1/cosec θ

cos θ = 1/sec θ

tan θ = 1/cot θ

Co-function Identities

sin (90°−x) = cos x

cos (90°−x) = sin x

tan (90°−x) = cot x

cot (90°−x) = tan x

sec (90°−x) = cosec x

cosec (90°−x) = sec x

Fundamental Trigonometric Identities

sin²θ + cos²θ = 1

Discount =10% of Rs.1700

=

100

10

×1700

=Rs.170

∴ Sale price =1700−170

=Rs.1530

Total sale price =1305+1530

=Rs.2835

Thus, the CUSTOMER would have to PAY Rs.2835

find the area of triangle ABC whose coordinates are A(4,-6)B(3,-2)C(5,2) then find the length of the median AD

Answer»

✪ GIVEN :-

Coordinates of A = ( 4 , -6 )
Coordinates of B = ( 3 , -2 )
Coordinates of C = ( 5 , 2 )

✪ To FIND :-

Area of the triangle ABC

✪ Solution :-

$\red\bigstar\: \boxed{\bf \green{Area = \frac{1}{2} \bigg[x_1(y_2 - y_3) + x_2(y_3 - y_1) +x_3(y_1 - y_2) \bigg ]}} \\$

Here

x₁ = 4
x₂ = 3
x₃ = 5
y₁ = -6
y₂ = -2
y₃ = 2

Substitute values in formula

$\longmapsto \sf Area = \frac{1}{2} \bigg[4(-2-2) + 3(2 + 6) +5( - 6 + 2) \bigg ] \\$

$\longmapsto \sf Area = \frac{1}{2} \bigg[4(-4) + 3(8) +5( - 4) \bigg ] \\$

$\longmapsto \sf Area = \frac{1}{2} \bigg[ - 16+24 - 20\bigg ] \\$

$\longmapsto \sf Area = \frac{1}{2} \bigg[ - 12\bigg ] \\$

$\longmapsto\boxed{\sf\purple{ Area = - 6 \: {unit}^{2}} }\\$
