To work out the average speed you would have to use the formula
AS = 15.0 ÷ 30.0 = 0.5 which is distance divided by time.
The you would do 0.5 x 60 = 30 (60 minutes = 1 hour)
So the average speed would be 30.0 km/h.
Answer:
option C and F
Step-by-step explanation:
Given excluded value is x=-5
Excluded value are the values that makes the denominator 0
Now we check out each option and see , in which option the denominator becomes 0 when x=-5
When denominator has (x+5) then when we plug in x=-5
(x+5) becomes (-5+5) =0
So we look at the options that has factor (x+5) in the denominator
In option C we have x^2 -25
When we plug in -5 for x then it becomes (-5)^2 - 25 =0
So x=-5 makes the denominator 0
-5 is an excluded value for option C
Last option f has x+5 in the denominator
x=-5 make the denominator 0
so , -5 is an excluded value for option F
The fraction can simplify down to

convert it to a fraction and the yearly increase is 1.5%
2. Well on average there are 365 days in a year. Dividing 93 million by 365 will get your increase per day.
There are 24 hours in a day, so that figure is further divided by 24.
There are also 60 minutes in an hour therefore furthermore divided by 60.
= 176 therefore true
The given question have mistake. The correct question is written below.
Question:
A dog jumps straight up in the air to catch a ball and lands on the ground 6.37 s later. Let h(t) represent the dog’s height, in meters, t seconds after he leaves the ground. Which equation models the dog’s height for a given time t?
Answer:
Option B:

Solution:
<u>General formula for the height of the projectile over time:</u>
(1) 
Where h = height in feet, t = time, v = initial velocity and s = initial height (feet)
(2) 
Where h = height in meters, t = time, v = initial velocity and s = initial height(meter)
Given initial velocity = 6.37 s and initial height is 0.
The height of the dog is in meters.
So, use second formula and substitute v = 6.37 and s = 0.



Hence option B is the correct answer.
Answer:
15 4/9 inches long
Step-by-step explanation:
5 4/9 × 3
When lining them vertically the 3 ends up under 5 in which you multiply and transfer the 4/9 next to the product of 15. Hope that helped!
