Please help!!

Answer:

e. None of the above is correct.

Step-by-step explanation:

The general formula for exponential growth is;

P= a(1 + r)^t

Where;

P = total number infected after a given time interval

a = initial number of infected people

r = growth rate of infection

x= time taken in weeks

Hence;

5000= 10(1 + 1.78)^t

5000/10 = (1 + 1.78)^t

500 = (1 + 1.78)^t

log 500 = tlog(1 + 1.78)

t = log 500/log(1 + 1.78)

t = 2.699/0.444

t = 6 weeks

The virus is spreading the fastest approximately 5.0 weeks after the jump.

An exponential equation is an algebraic expression that has an equality and at least one unknown in one of its exponents. To be considered an equation, an expression must have at least one unknown, which is an unknown number represented by a letter, and an equality relationship.

The general formula for exponential growth is;

P= a(1 + r)^t

Where;

Hence;

[tex]5000= 10(1 + 1.78)^t\\5000/10 = (1 + 1.78)^t\\500 = (1 + 1.78)^t\\log 500 = tlog(1 + 1.78)\\t = log 500/log(1 + 1.78)\\t = 2.699/0.444\\t = 6 weeks[/tex]

[tex]t=6-1=5 weeks[/tex]

Answer:

[tex](3,2)[/tex]

Step-by-step explanation:

The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.

[tex]y=-2x+8\\y=x-1[/tex]

In this system, the second equation is already solved for (y), thus one can substitute that expression into the other equation in the system.

[tex]x-1 = -2x + 8[/tex]

Now solve using inverse operations,

[tex]x -1 = -2x + 8\\+2x\\\\3x - 1 = 8\\+1\\\\3x =9\\/3\\\\x = 3[/tex]

Backsolve to find the value of (y), substitute in the value of (x), and solve for the value of (y).

[tex]y=x - 1\\[/tex]

Substitute,

[tex]y=(3)-1[/tex]

Solve,

[tex]y=2[/tex]

Thus, the answer to this system of equations is the following, [tex](3,2)[/tex].

Answer:

(x = 3 and y = 2)

Step-by-step explanation:

Ok, we have our 2 equations...

y = -2x + 8

y = x - 1

Lets solve them

y = -2x + 8 , y = x - 1

They both equal y  so I can put them together to equal out. Now our equation is...

x - 1 = -2x + 8

The next step is to get x on one side by itself, so change the negative symbol on -2 to addition...

3x - 1 = 8

Next step is to add 1 on both sides...

3x = 9

Divide both sides by 3...

x = 3

Now to do the other equation, which is easier.

y = x (3) - 1

or 

y = 2

Both are solved and we have ...

(x = 3 and y = 2)

Answer:

arc ABC = 196°

∠DCQ = 47°

Step-by-step explanation:

arc AD = 70°

∠D = 1/2 arc ABC = 98°

arc ABC = 98° * 2 = 196°

arc CD = 360° - arc AD - arc ABC = 360°-70°-196° = 94°

tangent chord angle DCQ = 1/2 arc CD = 1/2 * 94° = 47°

Answer:

[tex]VW = 50[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find VW

To find VW, we make use of the following equivalent ratios.

[tex]YX : XW = ZX : XV[/tex]

Where:

[tex]YX = ZX - ZY = 42 - 28 = 14[/tex]

[tex]XV = XW + VW = 25 + VW[/tex]

So, we have:

[tex]14 : 25 = 42 : 25 + VW[/tex]

Express as fraction

[tex]\frac{14 }{ 25 }= \frac{42 }{ 25 + VW}[/tex]

Divide both sides by 14

[tex]\frac{1}{ 25 }= \frac{3}{ 25 + VW}[/tex]

Cross multiply

[tex](25 + VW) * 1 = 3 * 25[/tex]

[tex]25 + VW = 75[/tex]

Solve for VW

[tex]VW = 75 -25[/tex]

[tex]VW = 50[/tex]

Answer: 280x^2 - 1000x - 480

Step-by-step explanation:

((7x + 3) * (x - 4))(40)

use foil

7x^2 - 28x + 3x -12

(7x^2 - 25x - 12) (40)

280x^2 - 1000x - 480

C: All real numbers.

Step-by-step explanation:

Domain means the interval of x=values that the function resides in. Since this quadratic function can go to both positive and negative infinity, there are no limits to the x-values so therefore the domain is all real numbers.

Answer: 1/8

Step-by-step explanation:(f‌‌‌‌‌‌‌÷g)(x) =

f(x) / g(x) =

2x / 22x

When we divide expressions with like bases, we subtract the exponents.

2(x - 2x) =

2-x

Now we substitute x = 3

So (f‌‌‌‌‌‌‌÷g)(3)

2-3

When we have a negative exponent, we perform the reciprocal of the expression and remove the negative sign from the exponent.

1/(23) =

1/8
