Answer:
x=2 y=2
Step-by-step explanation:
Answer:
(2,0); x = 2; y= 0
Step-by-step explanation:
add the system and u get y = 0. substitute in the first equation and u get x = 2
Answer:
25
Step-by-step explanation:
ABC is a right angle so ABD and DBC are <em>complementary angles</em> and their sum is equal to 90:
x + 55 = 90 subtract 55 from both sides
x = 25
Answer:
1.25
Step-by-step explanation:
it is what it is
To solve the problem shown in the figure attached in the exercise, you must follow the proccedure shown below:
1. You have that the<span> formula for calculate the velocity (v) in feet per second (ft/s), of an object that has fallen h feet is:
v=</span>√(64h)
<span>
2. The problem shown above asks for the velocity of an object that has fallen 23 feet. Therefore, to solve this exercise you only have to susbtitute h=23 feet into the formula for calculate the velocity (v), as below:
v=</span>√(64h)
h=23 feet
v=√(64)(23)
v=√(1472)
v=8√23
v=38.37 feet per second
3. Therefore, as you can see, the correct answer is the second option, which is: 38.37 feet per second
