The new strain of covid is spreading at the rate of 12% a week. Currently, there are 100,000 people infected with the virus. How long will it take before the virus has infected 800,000 people?

Answers

Answer 1

The covid strain will take 17.33 weeks to infect 800,000 people.

To solve the given problem, we only need to utilize the exponential function formula, which is stated as

[tex]A = Pe^{rt}[/tex]

Where A is the final value,

P denotes the starting value

The rate is r and time is given by t.

Given:

The rate of spread of the new strain of covid = 12% a week

Currently the number of people infected with the virus = 100,000

To determine how long will it take before the virus has infected 800,000 people, substitute the values in the formula

[tex]A = Pe^{rt}[/tex]

[tex]800000 = 100000e^{0.12*t}[/tex]

[tex]8 = e^{0.12*t}[/tex]

[tex]ln 8 = {0.12*t}[/tex]

[tex]t = ln 8/0.12[/tex]

[tex]t = 17.33 weeks[/tex]

Therefore, the covid strain will take 17.33 weeks to infect 800,000 people.

Step-by-step explanation:

Use the rule for the order of operations to simplify: 8+6(6-2(5-4))

Answers

Given the expression below

[tex]8+6(6-2(5-4))[/tex]

Step 1: Using PEMDAS rule

P=> Parenthesis

E=>Exponent

M=>Multiplication

D=>Division

A=>Addition

S=> Subtraction

From the rule above, we will start our simplification with the parenthesis

Step 1: simplify (5-4)

[tex]\begin{gathered} 8+6(6-2(5-4) \\ 8+6(6-2(1)) \end{gathered}[/tex]

Step 2: Expand 2(1)=> 2x1, then simplify (6-2(1))

differentiate y = (x²-7x)^5 (3x^5-5x)

Answers

The given expression is

y = (x²-7x)^5 (3x^5-5x)

To differentiate, we would apply the product rule which is expressed as

(fg)' = f'g + fg'

Let f = (x²-7x)^5 and g = (3x^5-5x)

f' = 5(2x - 7)(x²-7x)^4

g' = 15x^4 - 5

By applying the product rule, it becomes

y' = 5(2x - 7)(3x^5-5x)(x²-7x)^4 + (15x^4 - 5)(x²-7x)^5

B) at most 34%
C) at most 2.5%
D) at most 13.5%

Answers

The percentage of players serves were between 115 mph and 145 mph is approximately 16%.

Given :

The statistician reported that the mean serve speed was 100 miles per hour

the standard deviation of the serve speeds was 15 mph

Assume that the statistician also gave us the information that the distribution of serve speeds was mound-shaped and symmetric

To find :

What percentage of the player's serves were between 115 mph and 145 mph?

Solution :

μ =100

σ = 15

P ( 115 < x <145)

= P ( [tex]\frac{115-100}{15}[/tex] <  x-μ /6 <[tex]\frac{145-100}{15}[/tex] )

= P ( [tex]\frac{15}{15}[/tex] < z < [tex]\frac{15}{15}[/tex] )

= p ( 1<z<3)

= p( z<3)-p(z-1)

=0.9987-0.8413

=0.1574

p ( 115<xx<145)= 15.74 %

p( 115<x<145)= approximately 16%

The percentage of players serves were between 115 mph and 145 mph is approximately 16%.

Using vertical angles, it is found that:

A. The solution for y is of y = 4.

B. The angle measures are given as follows:

<A = 66º.<C = 114º.<D = 114º.

Vertical Angles

If two angles are opposite by the same vertex in crossing segments, these angles are called vertical angles, and they are congruent, that is, they have the same measure.

In the context of this problem, the angles of 6y + 42 and of 66 are vertical, hence the value of y is calculated as follows:

6y + 42 = 66

6y = 24

y = 24/6

y = 4.

Angles A and C are supplementary, meaning that the sum of their measures is of 180º, hence:

<C + 66º = 180º

<C = 180º - 66º

<C = 114º.

Angles C and D are vertical, hence the measure of angle D is calculated as follows:

<D = 114º.

what is the value of f(x)=2(0.75)^x when x=3

Answers

Answer: f(3) = 0.84375

Step-by-step explanation:

f(3) is asking for the value of the function when x = 3, not multiplying f by 3. (f(x) is basically the output, y)

So we just plug in 3 for x and simplify (use PEMDAS)

f(3) = 2(0.75)^3

f(3) = 2(0.421875)

f(3) = 0.84375

Answer:

[tex]\frac{27}{32}[/tex]

Step-by-step explanation:

It may be a bit easier to represent 0.75 as a fraction, since we can use the following property of exponents: [tex](\frac{a}{b})^x = \frac{a^x}{b^x}[/tex]

We can represent 0.75 as: [tex]\frac{3}{4}[/tex]

And substituting this into the function we get: [tex]f(x)=2(\frac{3}{4})^x[/tex]

calculating the value when x=3, we get: [tex]f(3)=2(\frac{3}{4})^3[/tex]

using the property previously stated we get: [tex]f(3)=2(\frac{3^3}{4^3})[/tex]

Raising each value to the exponent we get: [tex]f(3)=2(\frac{27}{64})[/tex]

When we multiply by two, we can simplify by splitting up 64, into two factors: 2 and 32, to get: [tex]\frac{2*27}{32*2}[/tex]

From here it's easy to see that we can cancel out the values 2, to get: [tex]\frac{27}{32}[/tex]
