Answer:
Domain = [0 , +∞)
Step-by-step explanation:
since r is the radius of a circle
Then
r must be a positive number.
Then
r ≥ 0
NOTE : if r = 0 ,then the circle reduces to a point .
The compass is the material that is not used when
making basic constructions.
To add, the compass is an instrument containing a magnetized pointer
that shows the direction of magnetic north and bearings from it. Also,
the remaining items in the choices are used to measure length and alignment,
which are essential in basic constructions.
Answer:
The time the catcher have to get in position to catch the ball before it hits the ground is nearly <u>5 seconds</u>.
Step-by-step explanation:
Given:
The variation of height of a ball above ground with time 't' is given as:
In order to reach the ground, the height will be 0 feet.
So, plugging in 0 for 'P(T)' and solving for time 'T', we get:
Solving for 'T' using the quadratic formula:
For a quadratic equation , the solutions are:
For the above equation,
Therefore, the values of 'T' are:
Negative time is neglected as time can't be negative.
Therefore, the time the catcher have to get in position to catch the ball before it hits the ground is nearly 5 seconds.
790-175x4=
take 175 and multiply it by 4 which gives you 700
Then subtract 700 from 790 and you get $90 after 4 years.
Your variables are 175 and 4
Answer:
450 x (1 + 0.5) ^ X = Phone subscribers
Step-by-step explanation:
Since a telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members, and the company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan, to determine the number of phone subscribers x months after the plan was launched, the following function must be considered and solved:
450 x (1 + 0.5) ^ X = Phone subscribers
So, for example, in 3 months, the number of subscribers would be the following:
450 x (1 + 0.5) ^ 3 = 1,518.75
Thus, in 3 months, the company would have 1,518 subscribers.
