The best order-of-magnitude estimate for 58,100:
C.10^5
Step-by-step explanation:
-2a + x
Putting values of a = - 2 and x = 7
-2(-2) + 7
4 + 7
= 11
Answer:
1.05 radians
Step-by-step explanation:
Given that Vanessa is skiing along a circular ski trail that has a radius of 2.5 km. She starts at the 3-o'clock position and travels in the Counter Clockwise direction.
She stops skiing when she is 1.244 km to the right and 2.169 km above the center of the ski trail.
This can be represented as (1.244, 2.169) on a circle of radius 2.5 km.
From the coordinate point (1.244, 2.169) derived, x=1.244 and y=2.169.
By the definition of tangent,

Vanessa swept out approximately 1.05 radians since she started skiing.
Answer:
b) 24
Step-by-step explanation:
We solve building the Venn's diagram of these sets.
We have that n(S) is the number of succesful students in a classroom.
n(F) is the number of freshmen student in that classroom.
We have that:

In which n(s) are those who are succeful but not freshmen and
are those who are succesful and freshmen.
By the same logic, we also have that:

The union is:

In which



So



So the correct answer is:
b) 24
