Answer:

The circumference of a circle is C = 2πr^2 (2nd power) Radius (r) is the distance from the center of the circle to the outside of it. To find radius divide the diameter (d) by 2. The diameter (d) of a circle is the radius (r) multiplied by 2. To find the diameter (d) you need to do C ÷ π.

For example):

Finding diameter - 76/3.14 = 24.19 (d)

Finding radius - 24.19/2 = 12.095 (r)

Answer:

2( w + 3 )

Step-by-step explanation:

Well first off, since theres no common term to factor out, I had to split 6 in half

so 2 w + 6 becomes 2w + 2 x 3.

I then factored out 2 because it's a common term,

which then leaves: 2( w + 3 )

basically, you have to find a common term to factor out, if you don't see one, you have to do something to a number so there's common terms.

Note: You probabily forgot to mention the two function. While after some research, I was able to find two functions based on which I would like to solve your query.

Answer:

The y-intercept of the equation will be (0, 4).

Step-by-step explanation:

Considering the assuming functions f(x) and g(x).

[tex]f(x) = -3x - 5[/tex]

[tex]g(x) = f(x)+9[/tex]

So,

[tex]g(x) = (-3x-5)+9[/tex]     ∵ [tex]g(x) = f(x)+9[/tex]

[tex]g(x) = -3x+4[/tex]  

Now, finding the y-intercept

so putting x = 0 in function g(x)

[tex]g(x) = -3(0)+4[/tex]

[tex]g(x) = 0+4[/tex]

[tex]g(x) = 4[/tex]

Therefore, the y-intercept of the equation will be (0, 4).

Answer:

Algebraic expression for 75 less than twice Mabel's score is 2m-75

Step-by-step explanation:

We need to translate the phrase 75 less than twice Mabel's score into algebraic expression.

Translating into algebraic expression

Let m represent Mabel's score

Twice Mabel's score = 2m

75 less than Twice Mabel's score = 2m-75

So, algebraic expression for 75 less than twice Mabel's score is 2m-75

Answer:

The answer is undefined

Step-by-step explanation:

The slope of the line that passes through points (2, -3) and (2, 13) is not defined.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The line that passes through points (2, -3) and (2, 13)

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Plug the values to find the slope of the line:

m = (13 + 3)/(2-2) = 16/0 = not defined

Thus, the slope of the line that passes through points (2, -3) and (2, 13) is not defined.

Answer:

$22.50

Step-by-step explanation:

My bad lol, I posted the answer under the wrong thing.

Answer: A) [tex]y=13e^{-0.1359t}[/tex]

              B) H = 5.10

              C) Yes

Step-by-step explanation: Exponential Decay function is a model that describes the reducing of an amount by a constant rate over time. Generally, it is written in the form: [tex]y(t)=Ce^{rt}[/tex]

A) C is initial quantity, in this case, the initial concentration of DDT. To determine r, using the data given:

[tex]y(t)=Ce^{rt}[/tex]

[tex]2.22=13e^{13r}[/tex]

[tex]e^{13r}=0.1708[/tex]

Using a natural logarithm property called power rule:

[tex]13r=ln(0.1708)[/tex]

[tex]r=\frac{ln(0.1708)}{13}[/tex]

[tex]r=-0.1359[/tex]

The decay function for concentration of DDT through the years is [tex]y(t)=13e^{-0.1359t}[/tex]

B) The value of H is calculated by [tex]y=C(0.5)^{\frac{t}{H} }[/tex]

[tex]2.22=13(0.5)^{\frac{13}{H} }[/tex]

[tex](0.5)^{\frac{13}{H} }=0.1708[/tex]

Again, using power rule for logarithm:

[tex]\frac{13}{H} log(0.5)=log(0.1708)[/tex]

[tex]\frac{13}{H} =\frac{log(0.1708)}{log(0.5)}[/tex]

[tex]\frac{13}{H} =2.55[/tex]

H = 5.10

Constant H in the half-life formula is H=5.10

C) Using model [tex]y(t)=13e^{-0.1359t}[/tex] to determine concentration of DDT in 1995:

[tex]y(24)=13e^{-0.1359.24}[/tex]

y(24) = 0.5

By 1995, the concentration of DDT is 0.5 ppm, so using this model is possible to reduce such amount and more of DDT.

Answer:

x = 2 or x = -3

Step-by-step explanation:

Given that ∆ABC ≅ ∆SRT, it follows that their corresponding side lengths are congruent to each other.

Thus:

[tex] RT = BC [/tex]

[tex] (x^2 + x) = 6 [/tex]

Solve for x

[tex] x^2 + x = 6 [/tex]

Subtract 6 from each side

[tex] x^2 + x - 6 = 6 - 6 [/tex]

[tex] x^2 + x - 6 = 0 [/tex]

Factorise

[tex] x^2 + 3x - 2x - 6 = 0 [/tex]

[tex] x(x + 3) -2(x + 3) [/tex]

[tex] (x - 2)(x + 3) [/tex]

x = 2 or x = -3

Answer:

Step-by-step explanation:

The formula F = 1.8C + 32 can be used to find the temperature in degrees Fahrenheit F when the temperature is given in degrees Celsius C. For what value is the temperature in degrees Fahrenheit equal to the temperature in degrees Celsius? Justify your reasoning by writing and solving an equation. (Hint: If Fahrenheit and Celsius are equal, they can be assigned the same variable.)

Answer:

x-8 is a factor of f(x)

Step-by-step explanation:

The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).

We are given the function

[tex]f(x)=-2x^3+17x^2-64[/tex]

And it's required to find if x-8 is a factor of f.

Applying the mentioned theorem, we only have to find f(8):

[tex]f(8)=-2\cdot 8^3+17\cdot 8^2-64[/tex]

Operating:

[tex]f(8)=-2\cdot 512+17\cdot 64-64[/tex]

[tex]f(8)=-1024+1088-64[/tex]

[tex]f(8)=0[/tex]

Thus, x-8 is a factor of f(x)

Answer:

Approximately 262%

Step-by-step explanation:

To find the percentage increase divide the new amount of offenses by the old amount of offenses:

2448/935 = 2.618

2.618 rounds to 2.62. Convert 2.62 into a percentage: 262%

The percentage increase between the amount of offenses in 2000 and the amount of offenses in 2019 is approximately 262%.

Answer:  89

Answer: x = 8

Step-by-step explanation: PLEASE GIVEBRAINLIEST IT HELPS ALOT

Answer:

x=8

Step-by-step explanation:

Follow the order of operations to simplify the equation:

5(x-3) +2x=41  

Start by multiplying into the parenthesis: 5x-15+2x=41

Combine like terms: 5x+2x-15=41 then simplify: 7x-15=41

Add 15 to both sides: 7x=56

Divide both sides by 7 to get x by itself: x=8

Answer:

0.85 of the original piece of lumber remains.

Step-by-step explanation:

Well, this lumber piece of lumber started as 2.5 meters long. Then, a 1.65 meter piece was cut off of it. All we need to do is subtract.

2.5 - 1.65 =

2.50 - 1.65 = 0.85.

Therefore, 0.85 of the original piece of lumber remains.

Hope this helps! :)
