Answer:
Step-by-step explanation:
3.57 x 10 ^ - 7 is the correct answer
Answer:
1.) Some
Step-by-step explanation:
Natural numbers do not contain negative numbers, but they do contain whole numbers like 1, 2, 3. So your answer would be some.
Given:
Solution:To solve the equation, it would be best if we remove the root. We remove the root by squaring the equation, but first we need to move the root and the content to the left side.


Then square both side to remove the root

After removing the root, move all terms to the left side
sec² x - 2 sec x + 1 = 0
Do factorization, remember that
a² - 2a + 1 = (a - 1)²
So,
sec² x - 2 sec x + 1 = 0
(sec x - 1)² = 0
sec x - 1 = 0
sec x = 1

= 1
cos x = 1
cos x = cos 0°
x = 0°
A. It is a parallelogram so, the formula is just simple base × height; 16cm × 9cm = 144cm²
B. It is a trapezoid so, the formula is base1 + base2 ÷ 2 × height; 25cm+ 44.67cm= 69.67cm ÷ 2 = 34.835cm × 20cm= 696.7cm²
C and D are irregular shapes - the diagram will show you how to do them...
