How could you convert a rate of 18,000 mph to miles per second

1 answer:

6 0

Hi there,

(18000 miles / 1 hour)(1 hour / 60 minutes)(1 minute / 60 seconds) adds up to 18000 miles / 3600 seconds, which then adds up to 5 miles / 1 second...

you should get a total of 5 miles per second

I hope I helped :)

On a hot summer day in the state of Washington while kayaking, I saw several swimmers jump from a railroad bridge into the Snoho

tamaranim1 [39]

Answer: the bridge is 11.025 m high

Step-by-step explanation:

Given that;

Time taken to hit the water t = 1.5 sec

height of bridge = ?

lets take a look at the equation of motion;

y(t) = y₀ + (1/2)at²

with initial velocity zero and we know that acceleration due to gravidity is 9.8m/s

we substitute

y(t) = (1/2)gt² = (1/2) × 9.8 × (1.5)²

y(1.5) = 11.025 m

Therefore, the bridge is 11.025 m high

Which graph represents the function f(x)=(x-5)^2+3

hammer [34]

Answer:

Parabola

Step-by-step explanation:

We are given that a function

$f(x)=(x-5)^2+3$

The given function is an equation of parabola along y- axis.

General equation of parabola along y- axis with vertex (h,k) is given by

$(y-k)=(x-h)^2$

$y=(x-h)^2+k$

Compare it with given equation then we get

h=5, k=3

Vertex of given parabola =(5,3)

Substitute x=0 then we get

$f(0)=(0-5)^2+3=28$

y-intercept of parabola is at (0,28).

Given that y = 9 cm and 0 = 23°, work out x rounded to 1 DP. у х 00 PLEASE HELP

lozanna [386]

Answer:

x ≈ 3.5 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin23° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{y}$ = $\frac{x}{9}$ ( multiply both sides by 9 )

9 × sin23° = x , then

x ≈ 3.5 cm ( to 1 dec. place )
