Find 7.1 times the diffrence between 60 and 14

saul85 [17]

Answer:

326.6

Step-by-step explanation:

First, find the <u>difference between 60</u> and 14; <em>60-14=46</em>

7.1 times the difference; <u>the difference is 46</u>

7.1 <u>times means to multiply</u>; <em>7.1*46=326.6</em>

hopefully this helped

Hurry To much points!

Montano1993 [528]

a) 0, 4, 8, 12, 16

explanation- simply add 4 to the previous number. 0+4= 4, 4+4= 8, 8+4= 12, etc etc.

b) 0, 8, 16, 24, 32

explanation- the same as letter a.

c) if you multiply the top number (the x value) by two, then you will get the bottom number (the y value)

explanation- 0+0= 0, 4+4= 8, 8+8= 16, 12+12= 24, and 16+16= 32

d) (0,0), (4,8), (8,16), (12,24), and (16,32)

explanation- the first number comes from the set in letter a (the x value) and the second number comes from the set in letter b (the y value).

e) -

explanation- find a spare piece of graph paper and put the points down. for example, (4,8) would be four places to the right on the horizontal line (the x-axis), and then down 8 places, still staying in the four postion. so four over, eight down. the vertical line is called the y-axis.

Hope this will help somewhat :)

Write an explicit formula for the arithmetic sequence 15.6, 15, 14.4, 13.8,..., and then find the 32nd term.

uysha [10]

Answer: the 32nd term is - 3

Step-by-step explanation:

The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + d(n - 1)

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = 15.6

d = 15 - 15.6 = 14.4 - 15 = - 0.6

n = 32

The explicit formula for the arithmetic sequence is

Tn = 15.6 - 0.6(n - 1)

We want to determine the value of the 32nd term, T32. Therefore,

T32= 15.6 - 0.6 (32 - 1)

T32 = 15.6 - 18.6

T32 = - 3

This hyperbola is centered at theorigin. Find its equation.Foci: (-2,0) and (2,0)Vertices: (-1,0) and (1,0)

beks73 [17]

SOLUTION

From the question, the center of the hyperbola is

$\begin{gathered} (h,k),\text{ which is } \\ (0,0) \end{gathered}$

a is the distance between the center to vertex, which is -1 or 1, and

c is the distance between the center to foci, which is -2 or 2.

b is given as

$\begin{gathered} b^2=c^2-a^2 \\ b^2=2^2-1^2 \\ b=\sqrt[]{3} \end{gathered}$

But equation of a hyperbola is given as

$\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1$

Substituting the values of a, b, h and k, we have

$\begin{gathered} \frac{(x-0)^2}{1^2}-\frac{(y-0)^2}{\sqrt[]{3}^2}=1 \\ \frac{x^2}{1}-\frac{y^2}{3}=1 \end{gathered}$

Hence the answer is

$\frac{x^2}{1}-\frac{y^2}{3}=1$
