Consider the sequence: 6, 10, 14, 18, 22,. . . . For this sequence, what is a3? a3 =.
Answer:
14
Step-by-step explanation:
A sequence is given to us , which is ;
[tex]\longrightarrow 6,10,14,18,22 [/tex]
We need to find out the third term of the sequence . The third term is 14 which is itself given in the question . We can also find it as ,
The given sequence is in Arithmetic progression since a common number is added to get the next term of the sequence .
Firstly let's find out the common difference . For this we can subtract any two consecutive terms . So ,[tex]\longrightarrow d = 10 -6\\[/tex]
[tex]\longrightarrow d =4 [/tex]
Now we know that the general term of the sequence in an AP is given by ,
[tex]\longrightarrow T_n = a + (n-1)d [/tex]
The first term is 6 and common difference is 4 . On substituting the respective values ,
[tex]\longrightarrow T_3 = 6 + (3-1)4\\[/tex]
[tex]\longrightarrow T_3 = 6 + 2(4)\\[/tex]
[tex]\longrightarrow T_3 = 6 +8\\ [/tex]
[tex]\longrightarrow \underline{\underline{T_3=14}} [/tex]

A card was selected at random from a standard deck of cards. The suit of the card was recorded, and then the card was put back in the deck. The table shows the results after 40 trials. What is the relative frequency of selecting a diamond?.
The relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.
What is relative frequency?The relative frequency of an event is the ratio of total number of favorable or desired outcome to the total number of trails done.
Given information-
The card is selected random from the deck of cards.
Total number of trails is 40.
It is known that the total number of diamond card in a standard deck of card is 11. There is total 40 trials is done in which a random card is selected.
As the relative frequency is the ratio of total number of diamonds to the total number of trials done. Thus,
[tex]f_r=\dfrac{11}{40}\\f_r=0.3[/tex]
In the percentage from,
[tex]f_r={0.3}\times100\\f_r=30[/tex]
Thus the relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.

Answer:
AC = 2.96
Step-by-step explanation:
Use the trigonometric ratio cosine:
cosine = adjacent ÷ hypotenuse
cos(65°) = AC ÷ 7
[tex]cos(65) = \frac{AC}{7}[/tex]
Multiply both sides by 7:
7(cos(65)) = AC
(Note: Set your calculator to degrees!)
And plug 7(cos(65)) into your calculator to get:
AC ≈ 2.96

Answer:
a. y = -x
b. Area = xy
c. x = -y
Step-by-step explanation:
a. The perimeter of the garden is the distance all the way around, in this would be x+y+x+y, or 2x + 2y. To solve for y, we’re trying to isolate it on one side. We need to subtract 2x to get 2y = -2x. Divide by 2 to get y = -x.
b. Area is length times width, so x • y, or xy.
c. To express in terms of x, we can take the equation y = -x and multiply it by -1 to get x = -y

An isosceles trapezoid has base lengths 3.4 and 5.8. With the area of 7.36. What is the height and perimeter of the trapezoid.
Answer:
Height (h) = 1.6
Step-by-step explanation:
Area of trapezoid = [(base1+base2)/2] * height
now we sub the values in the formula
7.36 = [(3.4+5.8)/2]* h
h= (7.36*2)/(3.4+5.8)
h = 1.6

An archer is shooting at targets. The height of the arrow is 5 feet above the ground. Due to safety rules, the archer must aim the arrow parallel to the ground. Write a function that represents the situation . Use h, for height ( feet) and for time (in seconds )

Answer:
15$ a day would be the estimate for 1 day
Step-by-step explanation:
Part a)
The diagonal line goes through (0,15) and (2,20)
Find the slope based on those points
[tex](x_1,y_1) = (0,15) \text{ and } (x_2,y_2) = (2,20)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{20 - 15}{2 - 0}\\\\m = \frac{5}{2}\\\\m = 2.5\\\\[/tex]
The y intercept is b = 15 because this is where the line crosses the y axis.
We go from y = mx+b to y = 2.5x+15.
Now plug in x = 1 to find the cost of renting for one day.
y = 2.5x+15
y = 2.5*1+15
y = 17.5
Another way to get the answer is to start at 1 on the x axis number line. Draw a vertical line upward until you reach the curve. From there, draw a horizontal line toward the y axis (refer to the diagram below). You should land somewhere between 15 and 20. The midpoint of which is 17.50
Answer: $17.50=====================================================
Part b)
We can do the reverse idea of the previous part.
Start at y = 25 on the y axis. Draw a horizontal line toward the curve. After reaching the curve, draw a vertical line down until you hit the x axis. You should arrive at x = 4.
Or you can use the algebraic approach since we know the cost equation
y = 2.5x+15
25 = 2.5x+15 ... plug in y = 25
25-15 = 2.5x
10 = 2.5x
2.5x = 10
x = 10/(2.5)
x = 4

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 18 miles per hour slower than the westbound train. If the two trains are 570 miles apart after 3 hours, what is the rate of the eastbound train?
Formula: Distance = rate * time
570 = (R+(R-18))*3
570 = (2R - 18)*3
190 = 2R-16
208 = 2R
R = 104
Eastbound Train: 86mph
