Answer:

-16394

Step-by-step explanation:

Pattern rule : Start at -2 and multiply it by -2.

-2 x -2 = 4

4 x -2 = -8

-8 x -2 = 16

16 x -2 = -32

- 32 x -2 = 64...so on

Answer:

es esto correcto? 25?

Step-by-step explanation:

Answer:

51.877 kg

Step-by-step explanation:

a

See attachment for calculations

b

The amount of salt in the tank after 4 hours is gotten by simply replacing t in the equation from a, with 4 hours. Since the t gotten in a above is in minutes, we'd convert hours to minute as well. If we do that, we have

t = 4 hours = 4 * 60 minutes = 240 minutes

y = 160/3 (1 - e^((-3 * 240)/200))

y = 160/3 (1 - e^(-720/200))

y = 160/3 (1 - 0.0273)

y = 160/3 (0.9727)

y = 51.877 kg

Therefore, the amount of salt in the tank after 4 hours is 51.877 kg

Answer:

5 2/10 miles or 5 1/5 miles, if you need to reduce fractions

Step-by-step explanation:

The way they wrote this is kind of confusing. Home to library = 1 3/10 miles. That's halfway to the park, so the distance to the park is 1 3/10 + 1 3/10 = 2 6/10 miles.

Then she had to ride that same distance home, so add

2 6/10 + 2 6/10 = 4 12/10 = 5 2/10

If your teacher has you reduce fractions, then it's 5 1/5 miles.

The number of miles did  marissa ride her bike in all should be 5 2/10 miles or 5 1/5 miles.

Since

She lives 1 3/10 miles from the library.

So here the distance to the park should be

= 1 3/10 + 1 3/10

= 2 6/10 miles.

Now we basically add it

= 2 6/10 + 2 6/10

= 4 12/10

= 5 2/10

hence, The number of miles did  marissa ride her bike in all should be 5 2/10 miles or 5 1/5 miles.

Answer:

hope it helped have a good day mate

Step-by-step explanation:

According to pythagoras theorem the square length of hypotenuse is equal to sum of other two sides

n^2 + 19^2 = 15^2

n^2 + 361 = 225 if we subtract 361 from both sides

n^2 = -136 but the root of square cannot be negative

Answer:

286.33

Step-by-step explanation:

Answer:

Consider the trapezoid ABCD. In this trapezoid BC=a and AD=b.

Since triangles BOC and AOD are somilar, then

[tex] \dfrac{AO}{OC}=\dfrac{DO}{OB}=\dfrac{AD}{BC}=\dfrac{b}{a}. [\tex]

OC/AO = OB/DO = BC/AD=/ba

Triangles OAE and CAB are similar

EO/BC=b/(a+b)

EO=ab/(a+b)

again

OF=ba/(b+a)

and.

EF=2a/(a+b) is arequired length.

x=9

Step-by-step explanation:

12=x+3

9=x

you set the sides equal to eachother bc they have the same angles!

Answer:

9

Step-by-step explanation:

x + 3 = 12 (both sides of triangle are equal, because angles are equal)

x= 12 - 3

x = 9

Answer:

The right answer is  neither

Step-by-step explanation:

I said because Exponential describes a very rapid increase. ... Exponential is also a mathematical term, meaning "involving an exponent." When you raise a number to the tenth power, for example, that's an exponential increase in that number. the part involves exponent is the y part same number multiple to it self to get the next answer  while the x part one specific number to get the next number which is linear but since theyre asking about the relationship it’s neither because both were supposed to have the same relationship linea for x and y or exponential for x and y but they both are different.

Answer:

y = 6

Step-by-step explanation:

3y/2 - 1 = 8

3y/2 = 8 + 1

3y/2 = 9

3y = 9 × 2

3y = 18

y = 18/3

y = 6

Answer:

y = 6

Step-by-step explanation:

[tex]\frac{3y}{2}[/tex] -1 =8

[tex]\frac{3y}{2}[/tex] -1 + 1 =8 +1

[tex]\frac{3y}{2}[/tex] = 9

[tex]\frac{3y}{2}[/tex] × 2 = 9 × 2

3y = 18

3y/3 = 18/3

y = 6

Double check:

[tex]\frac{3(6)}{2}[/tex] - 1 = 8

[tex]\frac{18}{2}[/tex] -1 =8

9 - 1 = 8

8 = 8
