We are given the following:
AB = 4800 miles
AO = 4000 miles
There is also a rule that states that a line tangent to a circle, will be perpendicular to the radius of the circle at the point of tangency. Therefore, triangle BAO is a right triangle.
We use Pythagorean theorem to solve for the hypotenuse BO.
BO = √(AO²+AB²) = √(4000²+4800²) = 6248 miles
But the problem asks for the length of BC. Since we know that OC is a radius of the circle, then:
BC = 6248 - 4000 = 2,248 miles.
The answer is C.
The expression for the 12 more than half of the postcard will be written as:- P/2+12=P
<h3>What is an expression?</h3>
The expression is defined as the relationship between the numbers and variables and is arranged in the form of an equation.
here we have the words in the question to convert it into an expression that is 12 more than half of the postcard.
The expression will be written as:-
P/2+12=P
Hence expression for the 12 more than half of the postcard will be written as:- P/2+12=P

Answer:
A. For every 1 inch of mercury the pressure increases, the boiling point is expected to increase by 1.9°F
Step-by-step explanation:
A regression model is in the form :
y = mx + c
With m being the slope = rate of change
In regression, the value of the slope gives the rate of change in y value per unit increase in the value of x
The slope in the question above is 1.9, this means for every unit increase in mercury pressure, then boiling point, y increases by 1.9°F
Answer:
.
Step-by-step explanation:
We are given a geometric sequence { -16, 4, -1, .... }
i.e. , , , ...
We will first find the common ratio 'r'.
Now,
i.e.
i.e.
i.e.
Similarly, i.e.
i.e.
So, we get that the common ratio is .
Now, the recursive formula for the geometric sequence is given by,
i.e.
i.e. .
Hence, the recursive formula for this sequence is .
