Answer:

Step-by-step explanation:

We can rule out the second and third because the y intercept in those graphs are not 1

Now lets look at the point 2,5 on graph a

y=1/2x+1

so 5=1+1 but that is false

D is the answer by elimination

First,let's find the slope-intercept form of equation which is y=mx+b, where y and x are coordinates, m is the slope and ,c is the y-intercept
y+6.75=0.25(x-1) y=0.25(2)-6.5
y+6.75-6.75=0.25x -0.25 -6.75 y=-6
y=0.25x-6.5
(2,-6) is the only correct answer I think is on the line with this equation.

Find the slope of the tangent line to the exponential function at the point (0,1) y=e^x/3

Sveta_85 [38]

The slope of a function is simply equal to its first derivative. So let us first take the 1st derivative of the equation:

y = e^(x / 3)

dy / dx = e^(x / 3) (1 / 3)

At x = 0:

dy / dx = slope = e ^(0) (1/3)

slope = 1/3

Step-by-step explanation:

7 + 3 = 10

+ 679 - 2056 = -1377

- 398 + 1 = -397

-23 - 237 = 260

2 - 6 = -4

-2 × 3 × -4 = 24

absolute value of -36 = 36

6 + 4 = 10

- 5928 - 965 = -6893

215 × 212 + 212 × 314 = 112148

(15 + 5) ÷ (15 + 5) = 20 ÷ 20 = 1

-457 + 1 = -456

- 218 -1 = -219

The overall balance for year 5 after taxes is $270.68

Step-by-step explanation:

Starting Balance = $1000

Interest gained = 10%

Income tax = 30%

For year 1

Finding 10% interest:

We will find 10% interest of 1000 and add it to the starting balance.

$=\frac{10*1000}{100}\\=100$

So, interest gained = $100

Overall Balance = 1000+100 = $1100

30% tax

30%of 1100

$=\frac{30*1100}{100}\\=330$

30% tax is $330

The tax paid is deducted from the balance

Overall balance after taxes = 1100-330 =$770

Year 2

Finding 10% interest:

We will find 10% interest of $770 as balance is $770 after tax deduction

$=\frac{10*770}{100}\\=77$

So, interest gained = $77

Overall Balance = 770+77 = $847

30% tax

30%of 847

$=\frac{30*847}{100}\\=254.1$

30% tax is $254.1

The tax paid is deducted from the balance

Overall balance after taxes = 847-254.1 =$592.9

For year 3

Finding 10% interest:

We will find 10% interest of $592.9 as balance is $592.9 after tax deduction

$=\frac{10*592.9}{100}\\=59.29$

So, interest gained = $59.29

Overall Balance = 592.9+59.29= $652.19

30% tax

30%of 652.19

$=\frac{30*652.19}{100}\\=195.657$

30% tax is $195.65

The tax paid is deducted from the balance

Overall balance after taxes = 652.19-195.65 =$456.53

For Year 4

Finding 10% interest:

We will find 10% interest of $456.53 as balance is $456.53 after tax deduction

$=\frac{10*456.53}{100}\\=45.65$

So, interest gained = $45.65

Overall Balance = 456.53+45.65= $502.18

30% tax

30%of 502.18

$=\frac{30*502.18}{100}\\=150.65$

30% tax is $150.65

The tax paid is deducted from the balance

Overall balance after taxes = 502.18-150.65 =$351.53

Year 5

Finding 10% interest:

We will find 10% interest of $351.53 as balance is $351.53 after tax deduction

$=\frac{10*351.53}{100}\\=35.15$

So, interest gained = $35.15

Overall Balance = 351.53+35.15= $386.68

30% tax

30%of 386.68

$=\frac{30*386.68}{100}\\=116.00$

30% tax is $116.00

The tax paid is deducted from the balance

Overall balance after taxes = 386.68-116 =$270.68

So, overall balance for year 5 after taxes is $270.68

The length of a rectangular garden is 5 feet longer than twice the width. The perimeter of the garden is 52 feet. Find the dimen

Leya [2.2K]

Width -w
length l= 2*w+5
perimeter P=2w+2l, 52=2w+2l

system of equations:
52=2w+2l ------> 26 =w+l (1)
l= 2*w+5 (2)

substitute value of l from second equation into the 1st
26=w+2w+5
26=3w+5
21=3w
w=7

l=2w+5, l=2*7+5, l=19

Answer:
system
52=2w+2l
l= 2*w+5
