Step-by-step explanation:

V – E + F = 2

We know that V = 5 and E = 8

Substitute these into the equation

5 -8+F = 2

-3+F =2

Add 3 to each side

-3+F+3 = 2+3

F=5

Answer:

A graph shows zeros to be ±3. Factoring those out leaves the quadratic

 (x-2)² +1

which has complex roots 2±i.

The function has roots -3, 3, 2-i, 2+i.

Step-by-step explanation:

Answer:

See below ~

Step-by-step explanation:

The function is :

f(x) = x⁴ - 4x² - 5

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

Plotting on a graph :

⇒ Once plotted on graph, check where the line of the function intersects the x-axis

⇒ Those will be the zeros of the function

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

Solution :

⇒ x = -2.236

⇒ x = 2.236

let me answer the last one first

compound interest is just an exponential sequence really, where the next value is some exponential amount of the previous.

hmmm that can happen in say, a bouncing ball, the 1st bounce is high, let it keep on boucing by itself and the next bounce is usually a compounded value of the previous one, since it's smaller it'd be a Decay type of equation.

hmmm it also happens in say population growth, of any organism, humans, bees, amoebas.

now let's do the others

[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$3000\\ r=rate\to 2.6\%\to \frac{2.6}{100}\dotfill &0.026\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years \end{cases} \\\\\\ A=3000\left(1+\frac{0.026}{4}\right)^{4\cdot t}\implies \boxed{A=3000(1.0065)^t} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\stackrel{\textit{after 15 years}}{t=15}\hspace{5em} A=3000(1.0065)^{15}\implies A\approx 3306.19 \\\\[-0.35em] ~\dotfill\\\\ ~~~~~~ \textit{Continuously Compounding Interest Earned Amount} \\\\ A=Pe^{rt}\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$3000\\ r=rate\to 2.6\%\to \frac{2.6}{100}\dotfill &0.026\\ t=years\dotfill &15 \end{cases} \\\\\\ A=3000e^{0.026\cdot 15}\implies A=3000e^{0.39}\implies A\approx 4430.94[/tex]

Th amount of money that Diana is left with is $8,430.23.

The first step is to determine the interest earned in the first year and the total amount that was made in the 2 years.

The formula used to determine the future value with monthly compounding is:

P(1 + r)^( n x m)

Where:

Total amount made in 2 years = $8000 x ( 1 + 5% / 12)^(12 x 2) = 8839.53

Interest earned in the first year = [ $8000 x ( 1 + 5% / 12)^(12) ] - 8000 = $409.29

Amount she is left with =  8839.53 - $409.29 = $8430.23

Answer:

a) 15/8   b) 25/18

Step-by-step explanation:

a) First bring all the fractions to a common denominator (I'm going to use 8th's). 5/8 is already simplified, 1/2=4/8, and 3/4=6/8. Then, simply add the numerators and leave the denominator:  [tex]\frac{5+4+6}{8} =\frac{15}{8}[/tex]

Since this can not be simplified any further, your final answer is 15/8.

b) Start by bringing all the fractions to a common denominator (for this problem, we'll use 18th's). 2/3=12/18, 1/6=3/18, and 5/9=10/18. Then just add all the numerators and leave the denominator the same: [tex]\frac{12+3+10}{18} = \frac{25}{18}[/tex]

Since this cannot be simplified further either, your final answer is 25/18.

Hope this helps! :)

Answer:

so to add we need to find lcm

Step-by-step explanation:

a) 5/8 + 1/2+3/4                            lcm of 2,4 and 8 = 8

5/8 = 5/8

1x4
2x4  =  = 4/8

3x2
4x2    = 6/8

5/8 + 4/8 + 6/8 = 15/8


b) 2/3 + 1/6 + 5/9                       lcm of 3 , 6 and 9 = 18

2x6
3x6  = 12/18

1x3
6x3      = 3/18

5x2
9x2 = 10/18

12/18 + 3/18 + 10/18 = 25/18

Based on the calculations, the sequence defined by the given function are 0.75, 1.1, 1.45​, 1.80 and 2.15.

In this exercise, you're required to create the first five (5) terms of the sequence defined by the given function as follows:

For the first term, we have:

f(1) = 0.75

For the second term, we have:

f(2) = f(2-1) + 0.35

f(2) = 0.75 + 0.35

f(2) = 1.1.

For the third term, we have:

f(3) = f(3-1) + 0.35

f(3) = 1.1 + 0.35

f(3) = 1.45.

For the fourth term, we have:

f(4) = f(3-1) + 0.35

f(4) = 1.45 + 0.35

f(4) = 1.80.

For the fifth term, we have:

f(5) = f(3-1) + 0.35

f(5) = 1.80 + 0.35

f(5) = 2.15.

Therefore, the sequence defined by the given function are 0.75, 1.1, 1.45​, 1.80 and 2.15.

Chelsea

12 × 3 = 36

48 × 4 = 192

Pierre

8 × 3 = 24

24 × 4 = 96

An equivalent expression is given by  (2 / x ^ 3) * sqrt (2)

We have the following expression

8 / x ^ 6

Rewriting we have

sqrt (8 / x ^ 6)

The expression consists of numbers and arithmetic operators. It does not contain equality or inequality symbols.

sqrt (2 * 4 / ((x ^ 2) * (x ^ 2) * (x ^ 2)))

(2 / (x * x * x)) sqrt (2)

The total length of the ribbon is 52 m.

Aleena initially cuts 3/8 of the ribbon, i.e. a length of (3/8)x.

1 - (3/8)x = (5/8)x.

i.e. (4/5) * (5/8)x = (20/40)x = (1/2)x

(3/8)x + (1/2)x = (3/8)x + (4/8)x = (7/8)x

That means  1 - (7/8)x = (1/8)x remains, and that is a length of 6.5 m.

1/8 of what number is 6.5?

Let y = the unknown number.

(1/8)y = 6.5

kung 5ft and a width of 9ft and the area of prism is 174 the answer is 5ft

Answer:

  (a)  This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.

Step-by-step explanation:

The equation of direct variation is ...

  y = kx

for some constant k. Here, we have x in hours and y in dollars. We can see if k is constant for the values given in the table.

__

Solving the direct variation formula for k, we have ...

  k = y/x

Using the table values, we can see if this is constant:

  k = dollars/hour = 10/2 = 20/4 = 30/6 = 40/8 = 5

The "rate of change" is constant at $5 per hour.

The function represents direct variation because it passes through the origin and has a constant rate of change of $5 per hour.

The approximation of the slope of the graph at t = 10 days using this secant lines are 11750 and -11750, respectively.

(a) t = 10 days and a day earlier

This means that:

t = 10 and t = 9

The function is given as:

[tex]N(t) = 100000e^{\frac{-(t - 10)^2}{8}}[/tex]

Calculate N(10)

[tex]N(10) = 100000e^{\frac{-(10 - 10)^2}{8}}[/tex]

Evaluate

N(10) = 100000

Next, calculate N(9)

[tex]N(9) = 100000e^{\frac{-(9 - 10)^2}{8}}[/tex]

Evaluate

N(9) = 88249.6902585

The slope is then calculated using"

[tex]m = \frac{N(10) - N(9)}{10 - 9}[/tex]

This gives

[tex]m = \frac{100000 - 88249.6902585}{10 - 9}[/tex]

Evaluate

m = 11750.3097415

Approximate

m = 11750

(b) t = 10 days and a day later

This means that:

t = 10 and t = 100

The function is given as:

[tex]N(t) = 100000e^{\frac{-(t - 10)^2}{8}}[/tex]

In (a), we have:

N(10) = 100000

Next, calculate N(11)

[tex]N(9) = 100000e^{\frac{-(11 - 10)^2}{8}}[/tex]

Evaluate

N(11) = 88249.6902585

The slope is then calculated using:

[tex]m = \frac{N(11) - N(10)}{11 - 10}[/tex]

This gives

[tex]m = \frac{88249.6902585 - 100000}{11 - 10}[/tex]

Evaluate

m = -11750.3097415
