Answer:
The coordinates of R are
Step-by-step explanation:
Given : M(5, 7) is the midpoint of RS. The coordinates of S are (6, 9).
To find : What are the coordinates of R?
Solution :
We have given,
A line RS which has a mid point M.
Let, the coordinates of R be
The coordinates of S are
The coordinates of M are
Applying mid-point formula,
Solve separately,
x- coordinate is
y- coordinate is
So, The coordinates of R are
sin
Answer:
is the same as by co-function identities
Step-by-step explanation:
Remember that complementary angles add up to 90°. The angle that i s complementary to 63° is 27°.
Also recall the co-function identities:
This means that .
Answer:
Frank can park 8.9 hours at the highest
Step-by-step explanation:
Here, we want to know the greatest amount of time that Frank can park given the amount he has to spend on parking.
From the question, we are told that he pays $2 for the hour and an extra $1 per additional hour.
Now, let the number of additional hour he is going to park be x. The bill for the additional hours will be ; $1 * x = $x
By adding this to the initial $2, we have the total $9.90
So, mathematically;
2 + x = 9.90
x = 9.9 -2
x = 7.9 hours
Now, the initial hour he parked is 1 hour + number of incremental hours = 1 + 7.9 = 8.9 hours
