Explanation

The secant of an angle θ is defined as 1/cos(θ).

For θ = 0, cos(0) = 1.

sec(0) = 1/cos(0) = 1/1 = 1.

Explanation

  8 × 125 = 1000.

Explanation

$$0.00049+0.201\times 430$$

Step 1: Multiply0.201 by $430$

$$0.201 times 430 = 86.43$$

Step 2: Add $0.00049$

$$86.43+0.00049=86.43049$$

Step 3: Check the options

None of the given answer choices match 86.43049, so the correct answer is:

$$mathbf{(d) text{none of these}}$$

Explanation

15 ÷ 5 = 3

15 divided by 5 equals 3, with no remainder.

Explanation

The additive inverse of " b" is " a "

To find :

(A) ab = 1

(B) a = b

(C) a + b = 0

(D) a - b = 0

Solution :

Step 1

Define the additive inverse of a number

We know that 0 is the additive identity

Let N be any number and M be the additive inverse of N

So by the property of additive inverse

N + M = 0 = M + N

Step 2

Choose the correct option

Here it is given that the additive inverse of " b" is " a "

So by the given condition

a + b = 0 = b + a

Hence a + b = 0

Explanation

Let's analyze the options:

1. 1.66666666666666…: This is a repeating decimal, which means it's a rational number (can be expressed as a fraction, 5/3).
2. 0.02002000200002…: This appears to be a non-repeating, non-terminating decimal, which is a characteristic of irrational numbers.
3. 0.142857142857: This is a repeating decimal, which means it's a rational number (can be expressed as a fraction, 1/7).

Based on the analysis, the answer is 0.02002000200002….

Explanation

8- 2 + 6 =?

6+6=12

Explanation

The first three even positive integers are: 2, 4, 6

Their average = (2 + 4 + 6) / 3 = 12 / 3 = 4

Explanation

If 200 was already there and you add 160, the total is:
$200+160=360$
