Answer:
x ≈ 8.3 ( to the nearest tenth )
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos41° = 
= 
= 
Multiply both sides by 11
11 × cos41° = x, thus
x ≈ 8.3
152.4cm. 2.54cm = 1in. 60in x (2.54cm/1in) = 152.4cm.
Answer:
an = 2.5n -0.2
Step-by-step explanation:
an = 2.5n -0.2
Since in the above case, the beaker has two sections each with different radius and height, we will divide this problem into two parts.
We will calculate the volume of both the beakers separately and then add them up together to get the volume of the beaker.
Given, π = 3.14
Beaker 1:
Radius (r₁) = 2 cm
Height (h₁) = 3 cm
Volume (V₁) = π r₁² h₁ = 3.14 x 2² x 3 = 37.68 cm³
Beaker 2:
Radius (r₂) = 6 cm
Height (h₂) = 4 cm
Volume (V₂) = π r₂² h₂ = 3.14 x 6² x 4 = 452.16 cm³
Volume of beaker = V₁ + V₂ = 37.68 + 452.16 = 489.84 cm³
Definition of additive inverse.- If two numbers are added together and the sum is zero, they are the additive inverse of each other.
<span>......................................... IF A + B = 0 , they are the additive inverse of each other.

<span>Multiplicative Inverse.- If two numbers are multiplied together and the product is one. They are the multiplicative inverse of each other, also called reciprocal. </span>
<span>......................................... A.B = 1 , they are the multiplicative inverse of each other.
