Answer:
C.) 7 and A.) 5
Step-by-step explanation:
Constants are numbers with no variable, they have no change, they are "constant"
Coefficients are the opposite, they are the numbers that are with variables and go through some sort of change
Answer:
Step-by-step explanation:
The length of an arc with measure 
and radius 
is given by 
. From the figure, we know that the radius of arc ADC is 4, but we don't know the measure of the arc. Since there are 360 degrees in a circle, the measure of arc ADC is equal to the measure of the arc formed by 
subtracted from 360. The measure of the arc formed by consists of two congruent angles, 
and 
. To find them, we can use basic trigonometry for a right triangle, since by definition, tangents intersect a circle at a right angle.
In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.
We have:
Therefore, 
The measure of the central angle of 
must then be 
Thus, the length of is equal to:
(three significant figures as requested by question).
first subtract the last equation from the first. this gives:-
-x + y = -8 .....................(1)
Then multiply the first equation by 2 and add it to the 2nd equations This gives
9x = 18
so x = 2
and from equation (1) y = -8 + 2 = -6
Substituting for x and y in the second equation
z = (24 -5(2) -12) / 2 = 1
Answer is choice b.
Number 16 is i believe 54units
Answer:
The June month salary is closest to her average monthly salary
The Sophie's average Monthly salary income = 3332.2
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given data Sophie's monthly earnings below
June $3,614
July $2,873
August $4,464
September $3,721
October $1,989
<em>The mean or expected number </em>
<em> = ∑x/n</em>
<em>The Sophie's average Monthly salary income</em>
<em> = </em>
<em></em>
<em> =</em>
<em></em>
<em> = 3332.2</em>
<em>The June month salary is closest to her average monthly salary </em>
