Answer:

1200 i think

Step-by-step explanation:

i used a calculator since its hard for me to do mental math

question 2

(sorry i replied late i was doing some of my school work)

so you make A be equal to 5000 since you want to know when his account will be that much money sooo

5000 = 2000(1.07t)

you divide 2000 from both sides

5000/2000 = 1.07t

5/2 = 1.07t

now you have to isolate t to solve for it

soo divide 1.07 to both sides

5/2 / 1.07 = t

t is equal to about 2.34 or 2 years (depends on what it tells you to round to) in the calc t is 2.336448598

so in maybe 2 years he'll have 5000 dollars

[tex]f^{-1}(x) = 3-7x\\\\[/tex]

=====================================================

Work Shown:

[tex]f(x) = \frac{3-x}{7}\\\\y = \frac{3-x}{7}\\\\x = \frac{3-y}{7}\\\\7x = 3-y\\\\7x+y = 3\\\\y = 3-7x\\\\f^{-1}(x) = 3-7x\\\\[/tex]

The idea is to swap each x and y, then solve for y to find the inverse.

Answer:

2:50 p.m.

Step-by-step explanation:

After he got home, his activities were:

homework: 45 minutes

break & snack: 35 minutes

baseball practice: 1 hour 55 minutes

1 hour = 60 minutes

Total time of activities:

45 minutes + 35 minutes + 60 minutes + 55 minutes = 195 minutes

195 minutes = 180 minutes + 15 minutes = 3 hours 15 minutes

Now we subtract 3 hours 15 minutes for 6:05 p.m.

   6:05

-   3:15

----------

We need to borrow 1 hour from 6 hours. 1 hour is 60 minutes. 6 hours becomes 5 hours. We add the 1 hour as 60 minutes to the 5 minutes.

   6:05                               5:65

-   3:15         -------->        -   3:15

-----------                          ----------

Answer:I think it would be 28

Step-by-step explanation:

I think you mean 1+x=24+5, so that's what i'm answering

1 + x = 24 + 5

1 + x = 29

-1.        -1

x= 28

5x + 2y = 2120

x + y = 574

2y = 2120 - 5x

2y = 1148 - 2x

1148 - 2x = 2120 - 5x

-972 = -3x

x = 324

574 - 324 = y

y = 250

Answer:

287

Step-by-step explanation:

Sum of A Finite Arithmetic Sequnece is

[tex] \frac{a _{1} + a _{n} }{2} n[/tex]

Where a1 is first term

an is final term

N is the number of terms.

We know a1 is 1

An is 40 but we don't know n.

To find n, we use the definition of a Arithmetic Sequence

[tex]a _{n} = a + (n - 1)d[/tex]

where d is the common difference. Let use the final term, 40 as a example.

Here the common difference is 3 so we have

[tex]40= 1 + (n - 1)3[/tex]

[tex]39 = 3(n - 1)[/tex]

[tex]13 = n - 1[/tex]

[tex]14 = n[/tex]

So we have 14 terms in this finite series.

Now we compute

[tex] \frac{1 + 40 }{2}(14) = \frac{41}{2} (14) = 41 \times 7 = 287[/tex]

So the answer is 287

Every month, the number of tigers decays by a factor of 0.97

Step-by-step explanation:

khan academy!

Every month, the number of tigers decays by a factor of 0.97.

We have given that,

Simone is an ecologist who studies the change in the tiger population of Siberia over time.

An exponential function is a type of function in math that involves exponents. A basic exponential function is of the form f(x) = b^x, where b > 0 and b ≠ 1.

The relationship between the elapsed time t, in years, since Simone started studying the population, and the number of tigers, N(t) year ​ right parenthesis, is modeled by the following function: N year(t)=612⋅(2/3)^t

Answer:

1) 8x - 24 = 24

2) 8x - 24 + 24 = 24 + 24

3) 8x = 48

4) x = 6

Step-by-step explanation:

Bolded are the answer choices:

4(2x - 6) = 24

First, distribute 4 to all terms within the parenthesis:

4(2x - 6) = 24

(4 * 2x) - (4 * 6)

(8x) - (24) = 24

8x - 24 = 24.

Next, add 24 to both sides of the equations:

8x - 24 (+24) = 24 (+24)

8x = 24 + 24

8x = 48

8x - 24 + 24 = 24 + 24

Then, divide 8 from both sides of the equation:

(8x)/8 = (48)/8

x = 48/8 = 6

8x = 48

x = 6
