A Formula for calculating displacement (distance from a point) is -
[tex]s = ut + \frac{1}{2} {at}^{2} [/tex]
A) Calculate u when s = 120, a = 2 and t = 4
Answer:
s=ut +atsq/2
120=4u+4sq
4u=104
u=26m/sec
Answer:
26 m/s
Step-by-step explanation:
Given
[tex]s = ut + \frac{1}{2} {at}^{2} [/tex]
When a = 2 , s = 120 and t = 4
Then
[tex]120 = u \times 4 + \frac{1}{2} \times 2 \times {4}^{2} \\ 120 = 4u + 16 \\ 120 - 16 = 4u \\ 104 = 4u \\ u = \frac{104}{4} \\ u \: = 26
Hope it will help :)❤
In a right-angled triangle ,right angled at B,if AB=5cm andAC=13cm ,then BC=
Answer:
BC = 12cmStep-by-step explanation:
by phythagoras theorm
AB² + BC² = AC²
5² + BC² = 13²
25 + BC² = 169
BC² = 169 - 25
BC² = 144
BC = √144
BC = 12cm

I’m having trouble with this plz help.
Answer:
The answer is 56. Here's why:
Step-by-step explanation:
Pythagorean Therom works for any right triangle, and it states (a)²+(b)²=(c)². A and B are the height and base, and C is the hyptoanuse. We don't know the height, but we know the rest of the information:
(a)²+(33)²=(65)². This simplifies to (a)²+1089=4225. If we subtract 1089 from each side, we get (a)²=3136. The √3136 (Sqaure root of 3136) is 56.

Please help!!! Find the value of h for the parallelogram shown.
Answer:h=11.2
Step-by-step explanation:
From the figure, we can write
[tex]\Rightarrow \sin x=\dfrac{8}{10}=\dfrac{4}{5}\\\\\Rightarrow x=53.13^{\circ}[/tex]
Also, [tex]\sin x[/tex] can be written as
[tex]\Rightarrow \sin x=\dfrac{h}{14}\\\\\Rightarrow \dfrac{4}{5}=\dfrac{h}{14}\\\\\Rightarrow h=11.2\ \text{units}[/tex]
Answer: h = 11.2

Brianna loves to compete in triathlons. At a race a few months ago, she finished in 360 minutes. At a race yesterday, she took 30% more time to finish. What was her time at yesterday's race?
Answer:
468 minutes
Step-by-step explanation:
Given data
At a race a few months ago, she finished in 360 minutes
let us find 30% of 360 minutes
=30/100*360
=0.3*360
=108 minutes
Hence she finished with an added time of 108minutes
Therefore, in all she finished in
=108+360
=468 minutes
A survey of teens showed that teens in Pittsburgh aged 12–17 spend 15.8 hours per week online. Teens in Miami/Ft. Lauderdale spends 14.2 hours per week online. Write and solve an additional equation to find the difference in time spent online by teens in these cities.
Answer:
1.6 hours
Step-by-step explanation:
Given that:
Time spent by Pittsburgh teens, p= 15. 8 hours
Time spent by Miami teens, m = 14.2 hours
The difference in time spent by the teens from these two cities is given by:
Time spent by Pittsburgh teens - Time spent by Miami teens
p - m
15.8 - 14.2 = 1.6 hours
