Answer:
Option D.The number of dollars it costs to rent the house for 10 days
Step-by-step explanation:
we have
f(x) -----> the total cost for renting a vacation house
x ------> the number of days rented
we know that
f(x)=10+250x
so
For x=10 days
substitute in the function
f(10)=10+250(10)=$2,510
f(10) represent the number of dollars it costs to rent the house for 10 days
Answer:
d) 135º
Step-by-step explanation:
Note that the angle DCU is the sum of the angles DCB and BCU. The angle DCB is 90º because A B C D is a square, then all its angles are equal to 90º.
After attaching B U C to A B C D, we obtain a trapezoid A U C D. Since A U C D has at least one pair of parallel sides, then AU should be parallel to CD, thus the angle CBU must be 90º.
B U C is isoceles, so we conclude that other two angles must have the same size, and due to the sum of the angles of a triangle being 180º, then both BUC and BCU are equal to 45º
As a result, the angle DCU is equal to 90º+45º = 135º. Option d is the correct one.
The answer is 5 because if you add 10 to -10 it is 0 then add the 5 more and it is 5.
