Find the missing term(s) of the geometric sequence: 39, a2 , 975, ... Hint: r can be positive or negative.

Answers

9514 1404 393

Answer:

±195

Step-by-step explanation:

For some common ratio r, your missing term satisfies ...

39r = a2

a2·r = 975

So, ...

975 = 39r^2

25 = r^2

r = ±√25 = ±5

The missing term a2 = 39r could be either of 195 or -195.

HELPPP

Answers

Answer:

If he kept taking notes at the same pace, he would have 16 pages of notes in his notebook.

Step-by-step explanation:

By dividing the number of pages of notes taken by the time spent taking them, you can find his rate of note-taking, which is 4 pages an hour. By adding another hour of notes, he should have 16 pages of notes. But if this question is asking for 4 more hours, the answer would be 28 pages.

if y varies inversely as x, and y =35 when x =14, find x when y =15.

Answers

Answer:

[tex]x = 32 \frac{2}{3} [/tex]

Step-by-step explanation:

[tex]y = \frac{k}{x} ,where \: k \: is \: a \: constant.[/tex]

Let's find the value of k first.

When y= 35, x= 14,

[tex]35 = \frac{k}{14} [/tex]

k= 14(35)

k= 490

Substitute the value of k into the equation:

[tex]y = \frac{490}{x} [/tex]

When y= 15,

[tex]15 = \frac{490}{x} [/tex]

15x= 490

x= 490 ÷15

[tex]x = 32 \frac{2}{3} [/tex]

Answers

Answer:

64 degrees.

Step-by-step explanation:

We are given that angle QRP is 32 degrees.

We are also given that angle PRS is 84 degrees.

Add those two angles to get the measure of angle QRS.

measure of angle QRS= 116 degrees.

Same-side interior angles are supplementary

So,

116+ angle PQR= 180

subtract both sides by 116.

PQR=64

Therefore the measure of angle PQR is 64 degrees.

Written by Katie Thompson-Chapter 3By the time we have managed to pull the now snoring unicorn out onto the driveway, the color in Joes face completely gone. HowWhereDid this thing come from? he asks, panting.What, afraid its real after all? I ask.He looks up at me and offers a half-smile. Who wants unicorns to be real if they look like that?I hide a laugh. WellNow we just have to figure out how to wake it up. I poke it a few times with my foot, trying to keep some distance. It just keeps snoring.Joe shrugs and bends down next to its ugly face and starts jiggling its shoulder, like hes trying to wake up a very old uncle.Suddenly its eyes open wide, and with an unbelievable grace, it stands upright. Joe jumps away to give it space, and I just keep staring at it. It walks over to the desert-style landscaping of my neighbors side yard and being perusing for its breakfast.That things a lot more agile than I imagined it would be, Joe says. We both stare at it as it saunters around, pulling up the grassy weeds from between the rock mulch. Sothats a unicorn.I look up at Joe and he's got this silly grin on his face. It's just so 'Joe' that I giggle. Do you believe that's what it is yet? I ask.I could if I wanted to, he replied.I looked up at him, questioning.That thing, he points to the unicorn. I could believe it was if I wanted to.The unicorn seems to have decided that it isnt going to find anything worth eating here and starts to walk down the sloping back yard to the next street. It looks almost like it belongs there, like a stray deer who often grazes around this part of town when no person is awake or watching. When it disappears from our sight, I feel like a ton of responsibility has been lifted from me.The whole morning seems almost trivial. Well, I say, I guess that is that?Joe shrugs, checks his watch, and motions toward the bus stop. We should get going, he says. I grab my bag, and we walk down the driveway.I don't know if that thing was a unicorn or not, he says, looking up into the sky like he might see a dragon flying around to confirm my claim. But I'm glad you called me this morning.Sorry I wasnot very nice, I say, hesitating.He laughs a little but keeps looking around. Then with a huge gulp of air, Do you believe we could be friends again? Like, real friends again?
