<h3>Explanation:</h3>
Average Speed = Total Distance / Total Time
Total Distance = 400m + 600m = 1,000m
Total Time = 35s
Average Speed = 1,000/35 = 28.57 m/s (approx.)
<h2>Answer:</h2>
Average Speed in two decimal places is <u>28.57 m/s (approx.)</u>
Answer:
x = 19
Step-by-step explanation:
![\sqrt[2]{x-3^3}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7Bx-3%5E3%7D)
= 64
= 4³
multiply each side by the exponent 2/3 so the radical sign on left is removed
()^2/3 = (4³)^2/3
x - 3 = 4²
x - 3 = 16
x = 19
Answer:
quadratic parent function
Step-by-step explanation:
squares cannot be negative no matter what you cannot square a number into a negative number which is why there are no negative y values because y is a function of X
Answer:
80
Step-by-step explanation:
The n th term of a geometric sequence is
= a₁
where a₁ is the first term and r the common ratio
We require to find a₁
Given
a₃ = 
, then
a₁r² = , that is
a₁ ×2² = ( divide both sides by 4 )
a₁ = 
, thus
= × 
= × 1024 = 5 × 16 = 80
Answer:
13w-7
Step-by-step explanation:
-6w + (-8) + 1 + (-7w)
(-6w+-7w) + (-8 + 1)
-13w + (-7) or -13w - 7
