Answer:
-6 -30x
Step-by-step explanation:
6(-3 + 2 - 5x)
Combine like terms inside the parentheses
6( -1-5x)
Distribute the 6 to all terms inside the parentheses
-6 -30x
Answer:
The standard form of a parabola is
y=ax2+ +bx+c, where a≠0.
To find the vertex, you need to find the x- and y-coordinates.
Answer:
(-3.07, 11.07)
Step-by-step explanation:
Given that a sports writer wished to see if a football filled with helium travels farther, on average, than a football filled with air. To test this, the writer used eighteen adult male volunteers. These volunteers were randomly divided into two groups of nine subjects each.
Group Group One Group Two
Mean 300.00 296.00
SD 8.00 6.00
SEM 2.67 2.00
N 9 9
The mean of Group One minus Group Two equals 4.00
standard error of difference = 3.333
df = 16
t = 1.2000
Margin of error = 3.3333* t critical = 3.3333*2.121
95% confidence interval of this difference: From -3.07 to 11.07
Answer:
2^4 or 4^2
Step-by-step explanation:
2^4= 2x2x2x2=16
4^2= 4x4=16
Answer:
<u>Initial</u><u> </u><u>speed</u><u> </u><u>is</u><u> </u><u>3</u><u>2</u><u> </u><u>m</u><u>/</u><u>s</u>
At uniform speed, acceleration is 0, (a = 0).
When speed reduced, (v - u) = 2.78 ms-¹, t = 1800 sec, s = 60 ,000 metres.
