Answer:
Total distance is 8 meters.
Step-by-step explanation:
First, let's take the equation and analyse it:
v(t) = 6 + t²
The delta t = 2
To find the acceleration, we need to differentiate v with respect to t like this:
dv/dt = d/dt (6 + t²)
= 2t
At t = 2, the change in velocity (dv/dt) = 2×2 = 4 m/s². This is the acceleration,a
The final velocity is given by v = 6 + (2)²
= 10 m/s
The distance is given by the formula:
s = ut + 1/2at²
initial velocity, u = 0
Therefore, the equation becomes s = 1/2at²
= 1/2× 4×4
=<u> 8 m Ans</u>

Answer:
x = 40
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the triangle on the left and calculate the third angle
Subtract the sum of the 2 angles from 180
third angle = 180° - (75 + 50)° = 180° - 125° = 55°
Consider the triangle on the right
The third angle = 55° ( vertical angles )
Subtract the sum of the 2 angles from 180
x = 180 - (55 + 85) = 180 - 140 = 40

Answer:
B. y = -6.2x
Step-by-step explanation:
If the y-intercept is zero (the graph passes through the origin), then its slope-intercept equation is ...
y = mx + b
y = mx . . . . . line with slope m and y-intercept of 0
When the slope is -6.2, the equation is ...
y = -6.2x
Answer:
7 ; 2 ; 8
Step-by-step explanation:
money for raffle= 350 pounds
money for quiz=14 multiplied by 4= 56
56+44= 100
money for membership fees= 20 multiplied by 20= 400
Ratio
Raffle :Quiz: Membership fees
350 : 100 : 400
35 : 10 : 40 (divided by 10)
7 : 2 : 8 (divided by 5)
