Find the 14th term of the geometric sequence below. Leave your answer in fraction form if necessary.
64,-32,16,-8

Answers

Answer 1

Step-by-step explanation:

First term (a) = 64 = t1

Second term (t2) = -32

Common ratio (r) = t2/ t1 = -32 / 64 = - 1/2

Now

Tn =

[tex]a {r}^{n - 1} [/tex]

[tex]t14 = 64 \: ( - \frac{1}{2}) ^{14 - 1} [/tex]

[tex] = 64 \: ( - \frac{1}{2} ) {}^{13} [/tex]

= - 64 * 1 / 8192

= - 1/128

Hope it will help :)❤

3/4h*19mi/1/4h

Answers

Answer:

57 miles

Step-by-step explanation:

3/4 h times 19mi / 1/4 h

= (3/4)(19/(1/4) (h)(mi/h)

= (3/4)(76) mi

= 57 mi

or, 3/4 hrs ÷ 1/4 hrs = 3 hrs

and 3(19) = 57

or, 19 mi/(1/4)h = 76 mph

you are doing this for 3/4 hrs, so (3/4)(76) = 57

Hugh made a recipe that yields 8 1/2 cups. If each serving is 1/4 cup, which expression will help Hugh determine the number of servings his recipe will yield?

Answers

I’m not 100% percent sure on this but I think you would divide!
Answer:
Its D, 8 and 1 over 2 ÷ 1 over 4

→ A recipe yields = 8(1/2) cups.
And,
→ Each serving is = (1/4) cups.
So,
→ The number of servings his recipe will yield = (Total recipe yields) ÷ (Each serving) = 8(1/2) ÷ (1/4) = 8 and 1 over 2 ÷ 1 over 4 (Option D).

Answer:

m= -1

x= 4/7

Step-by-step explanation:

Answer:

1)m= -1

2)x=4/7

Step-by-step explanation:

1)Subtract 7m from both sides.      2)Step 1: Subtract 2x from both sides.−5x+3−2x=2x−1−2x                              -5x+3-2x=2x-1-2x

                                                              -7x+3=-1

                                                         Step 2: Subtract 3 from both sides

−7x+3=−1                                           -7x+3-3=-1-3

Step 2: Subtract 3 from both sides.  -7x=-4

                                                            Step 3:Divide both sides by -7

−7x+3−3=−1−3                                       -7x/7=-4/7

−7x=−4

Step 3: Divide both sides by -7.              x=4/7
