Answer:

Option A.)

The answer is 1/√3

Step-by-step explanation:

3sin⁻¹ (2x/1 + x²) - 4cos⁻¹ (1 - x²/1 + x²) + 2tan⁻¹ (2x/1 - x²) = π/3

Put x = tanθ

3sin⁻¹ (2tanθ/1 + tan2θ) - 4cos⁻¹ (1 - tan2θ/1 + tan2θ) + 2tan⁻¹ (2tanθ/1 - tan2θ) = π/3

3sin⁻¹ (sin2θ) - 4cos⁻¹ (cos2θ) + 2tan⁻¹ (tan2θ) = π/3

3.2θ - 4.2θ + 2.2θ = π/3

⇒ 2θ = π/3

⇒ θ = π/6

∴ tan-1x = π/6 ⇒ x = tan (π/6) = 1/√3

Thus, The answer is 1/√3

Answer: The slope is -8/3

Step-by-step explanation: Use the slope formula y2-y1/x2-x1

so -9-7/2-(-4) = -16/6 which can be divided by 2 to get -8/3

Answer:

Step-by-step explanation:

70% is equal to 0.7 in other words 7/10 is the most simple form.

Answer:

Step-by-step explanation:

To add like terms, add the coefficients, not the variables.

The simplified expression is 4x+3y+ 6z.

Only combine terms which contain the same variable.

Answer:

2nd choice

Step-by-step explanation:

4(10-number)=28

4(10-y)=28

The second equation, 4(10 - y) = 28, represents the given sentence.

Two or more expressions with an equal sign are defined as an equation.

The given sentence is "4 times the difference of 10 and a number is equal to 28".

Let the unknown number be y, then the sentence can be written as:

4(10 - y) = 28

Hence, the second equation, 4(10 - y) = 28, represents the given sentence.

Answer:

8*9=72, I think and if is wrong i'm sorry

Step-by-step explanation:

x = first number

x + 1 = second number

1 / x + 1 / ( x + 1 ) = 17 / 72

[ 1 * ( x + 1 ) + 1 * x ] / [ x * ( x + 1 ) ] = 17 / 72

[ ( x + 1 ) + x ] / [ x * x + x * 1 ) ] = 17 / 72

( 2 x + 1 ) / ( x ^ 2 + x ) = 17 / 72 Multiply both sides by 72

72 * ( 2 x + 1 ) / ( x ^ 2 + x ) = 17

( 72 * 2 x + 72 * 1 ) / ( x ^ 2 + x ) = 17

( 144 x + 72 ) / ( x ^ 2 + x ) = 17 Multiply both sides by x ^ 2 + x

144 x + 72 = 17 * ( x ^ 2 + x )

144 x + 72 = 17 * x ^ 2 + 17 * x

144 x + 72 = 17 x ^ 2 + 17 x Subtract 144 x to both sides

144 x + 72 - 144 x = 17 x ^ 2 + 17 x - 144 x

72 = 17 x ^ 2 - 127 x Subtract 72 to both sides

72 - 72 = 17 x ^ 2 - 127 x - 72

0 = 17 x ^ 2 - 127 x - 72

17 x ^ 2 - 127 x - 72 = 0

The solutions are:

x = - 9 / 17 and x = 8

- 9 / 17 isn't positive integers so x = 8

first number = 8

second number = 8 + 1 = 9

Proof:

1 / x + 1 / ( x + 1 ) =

1 / 8 + 1 / 9 =

( 1 * 9 + 1 * 8 ) / ( 8 * 9 ) =

( 9 + 8 ) / 72 = 17 / 72

Answer:

39% decrease

Step-by-step explanation:

To find the decrease, subtract 55 from 90

90 - 55 = 35

Divide 35 by the original temperature -

35/90 = 0.388

Multiply 0.388 by 100 to find the percent -

38.8%

Round to the nearest percent -

The product of 2.3 x 0.5 using partial products is 1.15.

A product obtained by multiplying a multiplicand by one digit of a multiplier having more than one digit.(So, the 2 in 23 would actually be 20.) For instance, 23 x 42 would become (20 x 40) + (20 x 2) + (3 x 40) + (3 x 2).

Given:

The given integer is

2.3 x 0.5

=23x5/100

According to given question we have

By use of partial products we get,

The partial product method involves multiplying each digit of a number in turn with each digit of another where each digit maintains its place.

(20*00)+(20*5)+(3*00)+(3*5)

=0+100+0+15

=115

=115/100

=1.15

Therefore,  the product of 2.3 x 0.5 using partial products is 1.15.
