Write an
explicit formula for an, the nth term of the sequence 21, 27, 33, ....
Answer:
Step-by-step explanation:
Remark
This is an arithmetic series. Each term differs by 6 from the previous one.
Givens
a1 = 21
d = 6
Formula
a_n = a1 + (n - 1)*d
Sample
Try it.
Let's let n = 3 which we have the answer for.
a_3 = 21 + (3-1)*6
a_3 = 21 + 2 * 6
a_3 = 21 + 12
a_3 = 33
That's exactly what the 3rd term is.
Simplify the expression.

Write a rule for the linear function shown in the graph.
A. y = 2x - 2
B. y = -2x + 2
C. y = 1/2x - 2
D. y = -x + 2
Answer:
The answer is A (y = 2x - 2)
Step-by-step explanation:
B and D aren't correct because the y-intercept is a positive 2 instead of negative 2 like the graph shown. We're now left with A and C. Go on one point of the graph and count up or down to go on the same y value as the other point. Go left or right and count until you go to the same point. Remember that the slope equation is rise/run. Rise meaning up or down. Run meaning left or right.
Answer:
y = -x+2

Is the point (3, 11) a solution for the linear equation 1/3x + y = 12? Explain.
Answer:
Yes, because when the values are substituted in, the equation becomes a true statement
Step-by-step explanation:
plug in the values for x and y and see if the equation makes sense
x=3
y=11
1/3(3)+11=12
1+11=12
12=12
Since the above equation is true, the point is a solution for the linear equation.

Cándido normally pays $875 for bodily injury and property damage insurance. His insurance company increases premiums by 150% for 1 accident, 200% for 2-3 accidents, and 250% for 4 accidents. Find his premium for the year after he has three accidents to the nearest dollar.
Answer:
$1,700.
Step-by-step explanation:
Since Cándido normally pays $ 875 for bodily injury and property damage insurance, and his insurance company increases premiums by 150% for 1 accident, 200% for 2-3 accidents, and 250% for 4 accidents, to find his premium for the year after he has three accidents to the nearest dollar, the following calculation must be performed:
875 x 200 / 100 = X
875 x 2 = X
1,700 = X
Therefore, his premium for the year after he has three accidents is $1,700.
Answer:
premium = $ 875
increase 200%
875 * 200 / 100
=$1750

The the composition of f and g denoted by the expression (fg)(5) is equivalent to f(g(5))
What is composition of functions?The composition of two functions f and g is an operation where two functions f and g generates a new function h such that h(x)=f(g(x)).
First we find the value of g(x). If g(x)=y then f(g(x))=f(y).
The value of composition (fg)(x) is equal to f(g(x)).
Thus the value of (fg)(5) is f(g(5)) .
If g(5)=c , some c.
Then (fg)(5)=f(g(5))=f(c)
Hence the value of the composition of f and g of 5 is f(g(5)).

Answer:
1) x = 41.8 deg
2) x = 64.2 deg
3) x = 51.3 deg
Step-by-step explanation:
Problem 1
For angle x, 4 is the opposite leg and 6 is the hypotenuse.
sin x = 4/6
x = sin^-1 2/3
x = 41.8 deg
Problem 2
For angle x, 14 is the adjacent leg, and 29 is the opposite leg.
tan x = 29/14
x = tan^-1 29/14
x = 64.2 deg
Problem 3
For angle xm 25 is the adjacent leg, and 40 is the hypotenuse.
cos x = 25/40
x = cos^-1 5/8
x = 51.3 deg
