What’s this answer Im tried everything

Quite a vague question, I used desmos to graph the attached photo.

Answer:

[tex]Area=45\pi$ square inches[/tex]

Step-by-step explanation:

The radius, r of the expanding circle of oil is modeled by the function:

[tex]r(s)=3\sqrt{s}[/tex], where s is time in seconds.

When s=5

Area of a circle[tex]=\pi r^2[/tex]

Therefore, area of the oil spill when s=5 seconds is:

[tex]Area=\pi (3\sqrt{5})^2\\=\pi *3^2*(\sqrt{5})^2\\=\pi *9*5\\$Area=45\pi$ square inches[/tex]

The area of the spill when s=5 seconds is 45pi square inches.

Answer:

12

Step-by-step explanation:

We can use the pythagorean theorem giving us:

a^2+b^2=c^2

(6sqr2)^2 + (6sqr2)^2 = c^2

72+72=c^2

144=c^2

12=c

Answer:

[tex](x+2)^2 + (y-3)^2 = 10[/tex]

Step-by-step explanation:

The standard equation for circle is

[tex](x-a)^2 + (y-b)^2 = r^2[/tex]

where point (a,b) is coordinate of center of circle and r is the radius.

______________________________________________________

Given

center of circle =((-2,3)

let r be the radius of circle

Plugging in this value of center in standard equation for circle given above we have

[tex](x-a)^2 + (y-b)^2 = r^2 \ substitute (a,b) \ with (-2,3) \\=>(x-(-2))^2 + (y-3)^2 = r^2 \\=>(x+2)^2 + (y-3)^2 = r^2 (1)[/tex]

Given that point (1,2 ) passes through circle. Hence this point will satisfy the above equation of circle.

Plugging in the point (1,2 )  in equation 1 we have

[tex]\\=>(x+2)^2 + (y-3)^2 = r^2 \\=> (1+2)^2 + (2-3)^2 = r^2\\=> 3^2 + (-1)^2 = r^2\\=> 9 + 1 = r^2\\=> 10 = r^2\\=> r^2 = 10\\[/tex]

now we have value of r^2 = 10, substituting this in equation 1 we have

Thus complete equation of circle is [tex]=>(x+2)^2 + (y-3)^2 = r^2\\=>(x+2)^2 + (y-3)^2 = 10[/tex]

The value 250 represents the predicted value of antique in year 2014.

Given Expression,

[tex]250\times(1.12)^{t}[/tex]

Here [tex]t[/tex] represents the no. of years since 2014.

Now clearly 250 shows here the predicted price of the antique in year 2014 and [tex](1.12)^t[/tex] shows how much percent the product is increasing over the year.

Hence the value 250 represents the predicted value of antique in year 2014.

Answer:

(m-16)(m+4)

Step-by-step explanation:

To factor a quadratic expression

First write the variable in each parentheses, then put negative/ positive, after that ask yourself what numbers have the product of the coefficient of x^0 and the sum of x^1.

David correctly factored the expression m^2 - 12m - 64 and got (m - 16)(m + 4).

An equation can be factored into its factors by splitting the middle term of the equation.

m^2 - 12m - 64 = 0

⇒ m^2 - 16m +4m - 64 = 0

⇒ m(m - 16) + 4(m - 16) = 0

⇒ (m + 4)(m - 16) = 0

The factors of the equation m^2 - 12m - 64 = 0 are (m - 16)(m + 4).

Therefore, we have found that David correctly factored the expression m^2 - 12m - 64 and got (m - 16)(m + 4). The correct answer is option C or (3).

Answer:

3.625

Step-by-step explanation:

Line segment IK = 35.

This is a parallelogram, in which:

LJ is a line bisector of IK; line Imidpoint = line segment kmidpoint.

IK = (4x + 3) + (4x + 3)

35 = (4x + 3) + (4x + 3)

Simplify. Combine like terms:

35 = 8x + 6

Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS =

Subtraction.

First, subtract 6 from both sides:

35 (-6) = 8x + 6 (-6)

35 - 6 = 8x

29 = 8x

Divide 8 from both sides:

(29)/8 = (8x)/8

x = 29/8

x = 3.625

3.625 is your answer.

Answer:

X= 8

The reason why X equals 8 is because the gave you the measurement of points I and K. They have created an expression to find points I and K and all they ask you to do is find the value of x.

To find the value of x, think about the measurement of points I and K. The measurements of point I and K equals 35. So we have to substitute a number for x that would make the expression equal 35. This is how I did it, so I thought 4 times what would get me close to 35. Then 4*8 came to my head and that automatically equals 32 and then when you add the three you get 35!

The correct question is:

Brett is comparing the graphs of y = 2^x and y = 5^x. Which statement is true?

(1) The y-intercept of y = 2^x is (0,2), and the y-intercept of y = 5^x

is (0,5). [

(2) Both graphs have a y-intercept of (0,1), and y = 2^x is steeper.

(3) Both graphs have a y-intercept of (0,1), and y = 5^x is steeper.

(4) Neither graph has a y-intercept.

Answer:

(2) and (3) are true.

Step-by-step explanation:

The correct options are:

(2) Both graphs have a y-intercept of (0,1), and y = 2^x is steeper. Since X < 0

(3) Both graphs have a y-intercept of (0,1), and y = 5^x is steeper. Since X > 0
