Answer:
speed=24km/h or 6.67m/s
Step-by-step explanation:
Given data:
time taken = t =43 hours
distance covered = d = 1032 km
to find:
speed of the ship = v =?
solution:
as we know that speed is defined as the distance covered by an object in unit time.Formula
speed = distance covered /time taken
speed = 1032km/43hours
speed =24km/h or in international system of units the answer is 6.67m/s
Answer:
C: 12.5
Step-by-step explanation:
The sides x and 11 could be defined as the Adjacent angle and the Hypotenuse. This means that we will use the cos function to solve this.
First we can set up our equation
![cos28=\frac{11}{x}](https://tex.z-dn.net/?f=cos28%3D%5Cfrac%7B11%7D%7Bx%7D)
Next we can solve for x by multiplying by x and dividing by ![cos 28](https://tex.z-dn.net/?f=cos%2028)
![x=\frac{11}{cos28}\\\\x=12.458\\\\x=12.5](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B11%7D%7Bcos28%7D%5C%5C%5C%5Cx%3D12.458%5C%5C%5C%5Cx%3D12.5)
Answer:
C, Linear
General Formulas and Concepts:
<u>Algebra I
</u>
- Linear - Proportional relationship y = mx + b
- Nonlinear - Any graph that has a degree x higher than 1
Step-by-step explanation:
<u>Step 1: Define</u>
y = 7x + 14
<u>Step 2: Identify</u>
We see a linear equation (proportional relationship). Therefore, we have a linear equation.
BD=10 because it is symmetrical to AD.
