Answer:

  f(5) = 160

Step-by-step explanation:

The first several terms of the sequence are ...

  10, -20, 40, -80, 160, -320, 640, ...

Each term is -2 times the previous term.

  f(5) = 160

Dog is reliable.

Pencil is not correct.

Answer:

m<1 = 130°

m<2 = 50°

Step-by-step explanation:

Since given that line a is parallel to line b, and <1 and 130° are interior angles that alternate each other, therefore:

m<1 = 130° (alternate interior angle theorem)

Also,

130° and <2 lie on same side inside the parallel lines cut across by the transversal, therefore,

m<2 + 130° = 180° (same side interior angles theorem)

m<2 = 180° - 130°

m<2 = 50°

because the multiplication Slope of 2 perpendicular is -1

The original price was $1.50.

Answer:

  0.5 cm

Step-by-step explanation:

I prefer to write the proportion so the unknown value is in the numerator.

  c/sin(C) = b/sin(B)

  c = b×sin(C)/sin(B) = (2 cm)×sin(15°)/sin(105°) ≈ 0.535898 cm

  c ≈ 0.5 cm

Answer:

x = 1.2

Step-by-step explanation:

We can use a ratio to solve since they are similar triangles

6        (6+4)

----- = ---------

x             2

Using cross products

6*2 = (6+4)*x

12 = 10x

Divide by 10

12/10 = x

1.2 =x

Answer:

the answer is c 24 square meters

Answer:

Between 4 and 5

Step-by-step explanation:

Given

See attachment for graph

Required

Between which points is g(x) = 0

From the attachment, we can see that the graph crosses the x-axis at 4... and -1...

This means that

g(x) = 0 between 4 and 5

g(x) = 0 between -1 and -2

Going by the available options,

g(x) = 0 between 4 and 5

Answer:

8,648,640 different lineups are possible.

Step-by-step explanation:

The order in which the musics are there is important(lineup means that order matters), which means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

How many different lineups are possible?

7 musics from a set of 13. So

[tex]P_{(13,7)} = \frac{13!}{(13-7)!} = \frac{13!}{6!} = 8648640[/tex]

8,648,640 different lineups are possible.

Answer:

M) = 17

Step-by-step explanation:

You stated the answer right there. I think the question is missing more info but for now M=17

Answer:

x = 6

m<1 = 20°

m<CFE = 140°

Step-by-step explanation:

m<1 = (3x + 2)°

m<2 = (5x - 10)°

✔️Given that FB bisects AFC, therefore,

m<1 = m<2

Substitute

3x + 2 = 5x - 10

Collect like terms and solve for x

3x - 5x = -2 - 10

-2x = -12

-2x/-2 = -12/-2

x = 6

✔️m<1 = 3x + 2

Plug in the value of x

m<1 = 3(6) + 2

m<1 = 18 + 2

m<1 = 20°

✔️m<CFE = 180° - m<AFC (angles on a straight line)

m<CFE = 180° - (m<1 + m<2)

m<CFE = 180° - (20 + 20)

m<CFE = 180° - 40°

m<CFE = 140°

Answer:

-10

Step-by-step explanation:

you did not have to come on here for this annswer could have subtracted -7-3=-10

Answer:

Step-by-step explanation:

Any question that has less in it, is a question that you should pay attention to.

-7 -3 = - 10

You have to think of this the way you would money. Which would you rather owe - 7 dollars or - 10 dollars. Surely you would say that - 7 is better than - 10.

So - 10 looks like it is  three less than - 7

It works if the money thing makes sense to you.

If that doesn't work then think of a number line. As you keep on going left, the number looks like it is getting bigger, but is it. Again - 10 is smaller than - 7.

If you are talking about plus numbers then 3 less then 7 is not 10. It is 4.

Answer:

2X+3+X-6 =180

3X-3+3=180+3

3X=183

X=61

Answer:

x = 61

Step-by-step explanation:

The angles shown form a straight line

Angles that form a straight line add up to equal 180

Hence, 2x + 3 + x - 6 = 180

( note that we just created an equation that we can use to solve for x )

We now solve for x using the equation created

2x + 3 + x - 6 = 180

step 1 combine like terms

2x + x = 3x

3 - 6 = - 3

we now have 3x - 3 = 180

step 2 add 3 to each side

-3 + 3 cancels out

180 + 3 = 183

we now have 3x = 183

step 3 divide 3 from each side

3x / 3 = x

183 / 3 = 6

we're left with x = 61

Answer:

  43.1 in³

Step-by-step explanation:

The volume can be computed using the formula ...

  V = (π/4)d²h . . . . where d is the diameter and h is the height

For your dimensions, the volume is ...

  V = (π/4)(2.8 in)²(7 in) ≈ 43.103 in³

A full can contains a volume of about 43.1 cubic inches.

Solution :

The function :    [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex]   be a random permutation.

f is a permutation on [tex]$Z_{10}$[/tex] ,  i.e. f is permutation 10.

Now we know that the total number of distinct permutation on to symbolize 10!.

Each of these 10! permutation to a permutation function  [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex]  

Therefore, total number of permutation functions  [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex]   are 10!.

Now we want the total number of permutation functioning :

[tex]$f: Z_{10} \rightarrow Z_{10}$[/tex]   such that  f(0) = 0 and f(1)= 1

Now we notice that when f(0)=0 and f(1)=1, then two symbol '0' and '1 are fixed under permutation f.

So essentially when f(0) = 0 and f(1) = 1, f becomes permutation on 8 symbol.

Total number of permutation functioning  [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex]  , f(0)=0 and f(1)=1 are 8!

Now we want the probability that a random permutation  [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex]   satisfies f(0) = 0 and f(1) = 1.

The number of permutation function  [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex]  , i.e.

The probability that a random permutation  [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex]   satisfies f(0) = 0 and f(1) = 1 is

[tex]$\frac{8!}{10!} = \frac{8!}{10 \times 9\times 8!} =\frac{1}{10 \times 9}=\frac{1}{90}$[/tex]

Therefore, the probability that a random permutation  [tex]$f: Z_{10} \rightarrow Z_{10}$[/tex]   satisfies f(0)= 0 and f(1)=1 is  [tex]$\frac{1}{90}$[/tex]

Answer:

1. True, because when performing the calculations in both sides of the equation, we find that the left value is indeed the same as the right value

4-3+5 = 1+5 = 6

-6+8+4 = 2+4 = 6

6=6, so the sentence is correct

2+5 = 19-12 => 7=7, true

5-4-3-2-1 = 30-34-1 => -5=-5, true

2(x+5)-4x = 3(x-2)-5x+16

=> 2x+10-4x = 3x-6-5x+16

=> -2x+10 = -2x+10, true

Step-by-step explanation:

the other two sentences lead to false

4/5 + 1/5 = 2 - 1 - 1, => 5/5 = 1 = 0, false

2(x+8) = 2x-8, => 2x+16 = 2x-8 => 16=-8, false
