Answer:
[tex]a=5.43\ m/s^2[/tex]
Step-by-step explanation:
Given that,
Initial speed of a vehicle, u = 25 km/hr = 6.95 m/s
Final speed of a vehicle, v = 1200 km/hr = 333.34 m/s
Time, t = 60 s
We need to find the acceleration of the vehicle. It is equal to the rate of change of velocity. It can be given by :
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{333.34 -6.95 }{60}\\\\a=5.43\ m/s^2[/tex]
So, the acceleration of the vehicle is [tex]5.43\ m/s^2[/tex].
When the vehicle accelerates from 25 km/hr to 1200 km/hr in 60 sec, the acceleration of the vehicle is [tex]5.4 m/s^2[/tex], which is found by using the acceleration-time relation.
The acceleration (a) of a particle that is changing from initial velocity (u) to final velocity (v) in time (t) is given by,
[tex]a=\frac{v-u}{t}[/tex]
That is defined as the rate of change of velocity or change of velocity per unit time.
From the given,
[tex]u=25km/hr=6.9m/s\\v=1200km/hr=333.3m/s\\t=60sec[/tex]
Applying the acceleration-time relation,
[tex]a=\frac{333.3-6.9}{60} \\=\frac{326.4}{60}\\ =5.44m/s^{2}[/tex]
Hence, the acceleration of the vehicle is [tex]5.4 m/s^2[/tex].

A plane goes from a standstill to 350 mi/hr in about 45 sec. What is the plane's acceleration?
Answer:
The acceleration is 466.7m/s^2
Step-by-step explanation:
Given
[tex]u = 0m/s[/tex] -- Initial Velocity
It is 0 because the plane starts from a standstill
[tex]v = 350mi/h[/tex] -- final velocity
[tex]t = 45s[/tex] -- time
Required
Determine the acceleration
This is calculated using Newton's first equation of motion
[tex]v = u + at[/tex]
Convert time to hour
[tex]t = 45s[/tex]
[tex]t = \frac{45}{60}hr[/tex]
[tex]t = 0.75hr[/tex]
Substitute values for v, u and t
[tex]350 = 0 + a*0.75[/tex]
[tex]350 = 0.75a[/tex]
Divide both sides by 0.75
[tex]\frac{350}{0.75} = a[/tex]
[tex]466.67 = a[/tex]
[tex]a=466.67m/s^2[/tex]
Hence, the acceleration is 466.7m/s^2

Mr. Jimerson records the amount of snowfall that the local area recieves. 12am-1am: 0.3 inches | 1am-2am: 0.8 inches | 2am-3am: 1.36 inches |3am-4am: 2.019. If the total amount of snowfall at 7am is 7.8 inches. How much snow fell between 4am-7am? hurry pls
Answer:
5.781 inches.
Step-by-step explanation:
Since Mr. Jimerson records the amount of snowfall that the local area recieves, recording the following data: 12 am-1am: 0.3 inches | 1 am-2am: 0.8 inches | 2 am-3am: 1.36 inches | 3 am-4am: 2.019, if the total amount of snowfall at 7am is 7.8 inches, to determine how much snow fell between 4 am-7am the following calculation must be performed:
7.8 - 2.019 = X
5.781 = X
Therefore, since the amount of snow accumulated at 7 am was 7.8 inches, the snowfall between 4 and 7 am was 5.781 inches.

Answer:
The value of the third side c = 12.52
Step-by-step explanation:
Step(i):-
Given thatΔABC is a right angle triangle
AB = a = 6
BC = a =11
Find AC = ?
Step(ii):-
By using Pythagorean theorem
AC² = AB²+BC²
⇒ c² = 6² +11²
⇒ c² = 36 +121
⇒ c² = √157
c = 12.52
The value of the third side c = 12.52

simplify (5 square root 2) * ( 3 square root 2 )
Answer:
30
Step-by-step explanation:
multiply 5 x 3 and you get 15 then multiply the roots and you also get 2 so then you have to multiply 5 and 2 to get 30.
The solution is : the simplification of 5√2 × 3 √2 is: 30.
Here, we have,
given that,
5√2 × 3 √2
now, we need to simplify this, i.e. we have to multiply this.
so, we get,
multiply 5 x 3 and we get 15
then multiply the roots and we also get 2
i.e. √2 ×√2 = 2
so then you have to multiply 15 and 2 to get 30.
i.e. 15 * 2 = 30
so, we have,
5√2 × 3 √2
= 5 × 3 × √2 ×√2
=15 × 2
=30
Hence, The solution is: the simplification of 5√2 × 3 √2 is: 30.

Find all real zeros of the function y=-9x-1
A. -9
B. 1/-9
C. 1/9
D. -9 -1
Please select the best answer from the choices proided
Answer:
OPTION D
Explanation:
For zeros of the function (y is the function, a function of x) we need y = 0 so that in turn means we need - 9x - 1 = 0 or - 9x = 1 (i.e. add 1 to both sides); now divide by - 9, and x = 1/-9 which is exactly the same as - 1/9 or - (1/9) and this is the only zero of the function.
or
If y = -9x - 1,
When y = 0
0 = -9x - 1
0 + 1 = -9x - 1 + 1
1 = -9x
1/9 = -9x/9
1/9 = -x
1/[9 X (-1)] = -x/-1
- (1/9) = x
When x = 0
y = (-9 X 0) - 1
y = 0 - 1
y = - 1
