The answer to the following algebra is;

b² at b = 4 is 16

y /5 at y = 15 is 3

27/s at s = 9 is 3

q/3 + 4 at q = 3 is 5

How to solve algebraic expression?

Algebra is the system for computation using letters or other symbols to represent numbers, with rules for manipulating these symbols.

Given the following:

b² at b = 4

substitute b = 4

= 4²

= 4 × 4

= 16

y /5 at y = 15

substitute y = 15

= 15/5

= 3

27/s at s = 9

substitute s = 9

= 27/9

= 3

q/3 + 4 at q = 3

substitute q = 3

= 3/3 + 4

= 1 + 4

= 5

In conclusion, the algebraic expression is solved by substituting the value of the variables.

Todd's living room is rectangular and measures 9 meters by 3 meters. Beginning in one corner, Todd walks the length of his living room and then turns and walks the width. Finally, Todd walks back to the corner he started in. How far has he walked? If necessary, round to the nearest tenth.

Answers

Pythagorean theorem indicates the hypotenuse (the diagonal from corner to corner) is calculated by 9^2+3^2=c^2, so 81+9=c^2. The square root of c^2 is c, and the square root of 90 is ~9.487. Add the lengths of 9+3+9.487 to get 21.487. Round 21.487 to the nearest tenth, so the distance walked is 21.5 meters. I would get in the habit of rounding at the final step, but on this problem it wouldn’t matter. Peace!

a disease has hit a city. the percentage of the population infected t days after the disease arrives is approximated by ​p(t) for 0t. after how many days is the percentage of infected people a​ maximum? what is the maximum percent of the population​ infected?

The number of days would be 10 and the maximum percent of the population infected would be 25.752%.

What are exponential functions?

The exponential function, denoted by [tex]e^x[/tex], is a mathematical function. Unless otherwise specified, the term refers to a positive-valued function of a real variable, though it can be extended to complex numbers or generalized to other mathematical objects such as matrices or Lie algebras.

[tex]p(t) = 7te^{-\frac{t}{10}}[/tex]

percentage of infected people a maximum when p '(t) = 0

                    [tex]p '(t) = 7(1)e^\frac{-1}{10} +7te^\frac{-t}{10}(\frac{-1}{10})\\\\p'(t)=e^{-\frac{t}{10}}(7 -\frac{7t}{10})\\\\e^{-\frac{t}{10}}(7 -\frac{7t}{10})=0\\\\7 -\frac{7t}{10}=0\\\\t = 10[/tex]

Hence percentage of infected people reaches a maximum after 10 days

maximum percent of the population infected = p(10)

    [tex]p(10) = 7(10)e^{-\frac{10}{10}}\\\\p(10)=\frac{70}{e}\\\\P(10)=25.752\%[/tex]

Hence, the number of days would be 10 and the maximum percent of the population infected would be 25.752%.

we are given a bag of 35 different colored chips. there are 20 black chips and 15 white chips. you draw 11 chips at random, what is the probability of getting 5 black chips and 6 white chips1 ?

Answers

The probability of getting 5 black chips and 6 white chips is [tex]\frac{7}{22}[/tex].

What do you mean by probability?

Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A number between 0 and 1 represents the likelihood of an event, with 0 generally denoting impossibility and 1 denoting certainty.

According to data in the given question,

We have the given information:

Total number of different colored chips = 35

Number of black chips = 20

Number of white chips = 15

And you draw 11 chips at random.

Now, we will calculate the probability of getting 5 black chips and 6 white chips,

[tex]P(B) = \frac{5}{20} =\frac{1}{4} \\P(W) = \frac{6}{15} =\frac{2}{5} \\P( black and white ) = \frac{\frac{1}{4}*\frac{2}{5}}{\frac{11}{35} } \\=\frac{\frac{1}{2}*\frac{1}{5}}{\frac{11}{35} }\\=\frac{1}{10}*\frac{35}{11}=\frac{7}{22}[/tex]

Therefore, the probability of getting 5 black chips and 6 white chips is 7/22.

By evaluating the piecewise function we will see that the difference is:

f(1) - f(-7) = 3

How to find f(1) - f(-7)?

Here we have a piecewise function defined on the image, and we want to find the difference:

f(1) - f(-7).

First, let's find these values.

f(1) means that we need to evaluate the function in x = 1.

Notice that the second piece can be used on the domain 4 < x ≤ 1, so we need to use that part.

f(1) = -(1)^2 - 3*1

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

To evaluate in x = -7 we need to use the first piece of the function:

f(-7) = |-7 + 5| - 9

f(-7) = |-2| - 9 = -7

Then the difference is:

f(1) - f(-7) = -4 - (-7) = -4 + 7 = 3

Answer: 10 months

Step-by-step explanation:

40x >32x + 73

8x > 73

8x/8 > 73/8

x > 73/8 = 9.125

Round 9.125 to 10

The number of months that will take Lola to have more trading cards is obtained as 8.

What is linear inequality?

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

The number of cards with Lola and Joel are 432 and 505 respectively.

Suppose the number of required month be x.

Then, the inequality expression can be written for the given case as,

432 + 40x > 505 + 32x

⇒ 40x - 32x > 505 - 432

⇒ 8x > 63

⇒ x > 63/8

The number of months should be an integer value.

And, the nearest integer value of the greater than 63/8 is 8.

In the given question, a 15 foot ladder is leaning against a wall. if the top slips down the wall at a rate of 2 ft/s.

We have to find how fast will the foot be moving away from the wall when the top is 10 feet above the ground.

As given, 15ft ladder dy/dt= -2y=13ft

Let the length be x and height be y

So from the Pythagorean theorem

x^2+y^2=h^2

Now apply the above formula to get the value

x^2+y^2=15^2

Take the derivative with respect to time

2x * dx/dt+2y*dy/dt=0

dx/dt= -y/x *dy/dt

When y = 13

then x^2+13^2=15^2

x = 7.48

dx/dt= -13/748 * (- 2)

dx/dt= 3.476 ft/s

Answers

The equation of the circle with endpoints of a diameter at the points (3, 8) and (-5, 6) is x² + y² + 2x - 14y + 33 = 0.

How to determine the equation of a circle

These are the specified parameters:

Endpoints of a diameter at the points (3, 8) and (-5, 6).

Determine the center point of the circle (a, b).

(a, b) = ((x₁ + x₂)/2 , (y₁ + y₂)/2)

        = ((3 + (-5))/2 , (8 + 6)/2)

        = (-2/2 , 14/2)

        = (-1, 7)

The center point is (-1, 7).

Determine the radius of the circle (r).

[tex]\begin{aligned} r & = \frac{1}{2} \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\r & = \frac{1}{2} \sqrt{(-5-3)^2 + (6-8)^2} \\ r& = \frac{1}{2} \sqrt{(-8)^2 + (-2)^2} \\ r& = \frac{1}{2} \sqrt{64 + 4} \\ r & = \frac{1}{2} \sqrt{68} \end{aligned}[/tex]

Determine of the equation of the circle

(x - a)² + (y - b)² = r²

(x - (-1))² + (y - 7)² = (1/2 √68)²

x² + 2x + 1 + y² - 14y + 49 = 1/4 × 68

x² + y² + 2x - 14y + 50 = 17

x² + y² + 2x - 14y + 50 - 17 = 0
