Answer:

6

Step-by-step explanation:

geometric sequence is given as Tn=ar^n-1

where Tn is the last term,a is the first term, r is the common ratio, n is the nth term

hence 48=a2^(4-1)

48=a2^3

48=a8 (divide both by 8 to ramain with a)

6=a

therefore the first term is 6 .

Answer:

-31/17

Step-by-step explanation:

csc²α-cot²α=1

cot²α=csc²α-1=(25/7)²-1=(625-49)/49=576/49

α is in 2nd quadrant so cotα is negative.

cot α=-√(576/49)=-24/7

tan α=-7/24

cos β=√2/2

sec β=2/√2=√2

sec²β-tan ²β=1

tan ²β=sec²β-1

tan²β=(√2)²-1=2-1=1

β is in 1st quadrant ,so tan β is positive.

tan β=1

[tex]tan (\alpha -\beta )=\frac{tan \alpha -tan \beta }{1+tan \alpha tan \beta } \\=\frac{\frac{-7}{24} -1}{1+(\frac{-7}{24}) (1)} \\=\frac{-7-24}{24-7} \\=\frac{-31}{17}[/tex]

Answer:

3/10

Step-by-step explanation:

First we count the number of beans in total which is 20

Then we count the number of red beans which is 6

6/20 can be simplified to 3/10

Answer:

C) 3/10

Step-by-step explanation:

There are 6 red + 5 blue + 4 green + 5 black = 20 jelly beans in total

Since there are 6 red jelly beans, the probability of randomly selecting a red jelly bean is 6 red jelly beans / 20 total jelly beans = 6/20 = 3/10

Answer:

k = 2a - 1

k = 2(t - 1)

Step-by-step explanation:

Let :

Number of home runs Arthur hit = a

Number of home runs Kyle hit = k

Number of home runs Tom hit = t

Kyle's home runs, k in terms of Arthur's home run : Double the value of a ; then subtract 1

k = 2a - 1

Kyle's home runs in terms of Tom's home runs ;

Subtract 1 from t `

k = 2(t - 1)

Answer:

Yes, because its an rational number

Step-by-step explanation:

Solution: by division.

3/7 = 0.42857142857142857142…..

As you can see, the first six decimal places make a loop and become repetitive.

Then I proceeded to divide 100/6. That equals 16 remaning 4. Then counted four digits from0.428571. The 100th digit equals 5.

Answer:

A. y = -3/2x + 9

Step-by-step explanation:

In slope intercept form (y = mx + b), b represents the y-intercept. Therefore, simply look on the graph where the line intersects with the y-axis. In this case, that is all that was needed since we can clearly see that equation A is the only one with a y-intercept of 9.

Answer:

a

Step-by-step explanation:

any two points on the line are

(0,9 ) and (4,3)

slope=(3-9)/(4-0)=-6/4=-3/2

y intercept is 9

so eq. of line is y=-3/2x+9

Answer:

4.77

Step-by-step explanation:

because Circumference can be found with this equation

C = 2piR

we need to plug in 15 for Circumference and solve for its radius or R.

15 = 2piR

15/2pi = R

but we need diameter which is 2R so we just need to multiply the answer by 2.

15/2pi × 2 = Diameter

15/pi = D

approximately = 4.77

Answer:

The domain (input values) of the sine function is:

O B. all real numbers

The domain of the sine function will be all real number. Then the correct option is B.

The domain means all the possible values of x and the range means all the possible values of y.

Simply put, trigonometric functions also referred to as cyclic capabilities the functions of a triangle's inclination.

Let the sine function be f(x) = sin x.

It is a function that repeats itself in a particular time interval.

The domain of the sine function will be all real number.

And the range of the sine function will be [1, –1].

Then the correct option is B.

The graph of the sine function is given below.
