Answer:
(5, -1)
Step-by-step explanation:
Add the x-coordinates and divide by 2.
Add the y-coordinates and divide by 2.
x-coordinate of midpoint: (2 + 8)/2 = 10/2 = 5
y-coordinate of midpoint: (-5 + 3)/2 = -2/2 = -1
Midpoint: (5, -1)
Answer:
x = 6
Step-by-step explanation:
The radius in this case measures; 20/2 = 10 since the diameter is 20.
The chord measuring 16 units has been bisected, hence each portion measures 8 units.
We now apply Pythagoras theorem since we are dealing with a right angled triangle with 2 given sides;
x^2 = 10^2 - 8^2
x^2 = 36
x = 6
For this case we have an equation of the form:
h (t) = (1/2) at2 + vot + h0
Where:
a: acceleration
vo: initial speed.
h0: initial height
Substituting values we have:
h (t) = - 16t2 + 19t + 110
The initial speed is then:
vo = 19 feet / s
Answer:
The initial velocity when the rock is thrown is:
vo = 19 feet / s
Answer:
Hence the expression 
Step-by-step explanation:
Explanation
- The given expression is (4z-y)(z-6).
- We have to multiply the given expression.
- Multiply the (4 z-y) by -6, multiply the (4 z-y) by z then add like terms.
