Answer: Then Bokurano : ours?

Step-by-step explanation:

(0,0) (1,45) (2,90) (3, 135) (4, 180) etc, etc

Answer:

(4, 180)

Step-by-step explanation:

Choices: (3,5), (4,60), (4,180), (5,9)

y = 45x

The value of y is 45 times the value of x.

The only point in which that is true is (4, 180) since 45 * 4 = 180.

Step-by-step explanation:

Each row cannot have the same number of trees.

In mathematics, the term "divisibility" describes a number's ability to be divided by another number in an equal amount without any residue. For instance, it's simple to understand how 40 by 4 can be divided. A huge piece of land that can be divided into smaller chunks and sold separately is said to be divisible, much as it is obvious when you cut into a pan of brownies and distribute equal amounts to each of your friends.

As per the given data:

Number of apple trees = 987

Number of rows = 9

To find whether each row has the same number of trees:

If 987 is divisible by 9 then, the same number of trees can be there else not.

= (987/9) = (329/3) = 109.667

Not divisible, so same number of trees cannot be there.

Hence, each row cannot have the same number of trees.

Answer:

The equation of the circle is [tex]x^2 + y^2 = \frac{1}{4}[/tex]

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

Centered at the the origin

Center (0,0), which means that [tex]x_0 = 0, y_0 = 0[/tex]

radius of 1/2

This means that [tex]r = \frac{1}{2}[/tex]

Equation:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

[tex](x - 0)^2 + (y - 0)^2 = (\frac{1}{2})^2[/tex]

[tex]x^2 + y^2 = \frac{1}{4}[/tex]

The equation of the circle is [tex]x^2 + y^2 = \frac{1}{4}[/tex]

Find two points and draw a line through them

y = 1/2(2) + 5

y = 1 + 5, 6

One point is (2,6)

y = 1/2(0) + 5

y = 5

Second point is (0,5)

I inserted a graph on desmos for example

Step-by-step explanation:

Rewrite in slope-intercept form.

[tex]y = \frac{1}{2} x + 5[/tex]

Use the slope-intercept form to find the slope and y-intercept.

Slope is : 1/2

y-intercept: (0,5)

Any line can be graphed using two points. Select two x values, and plug them into the equation in order to find the corresponding y values.

Step-by-step explanation:

Using the "diamond method" for factoring a quadratic, the top number is the product of the leading coefficient and the constant. For this quadratic, it is ...

  (1)(5) = 5

The very top number is 5.

Answer:

By examining the line plot, we find the number with the maximum number of crosses or occurrences. This gives the mode of the data set. We find the smallest and the largest number from the data set and find their difference and this difference is the range of the given data set.

• Hypotenuse (H) = 15 in

• Base (B) = 12 in

• Perpendicular (P) [x]

By using pythagoras property,

[tex] \longmapsto \sf { H^2 =B^2 + P^2 } [/tex]

[tex] \longmapsto \sf { (15)^2 =(12)^2 +(x)^2 } [/tex]

[tex] \longmapsto \sf { x^2 = (15)^2 - (12)^2 } [/tex]

[tex] \longmapsto \sf { x^2 = 225 - 144 } [/tex]

[tex] \longmapsto \sf { x^2 = 81 } [/tex]

[tex] \longmapsto \sf { x = \sqrt{81} } [/tex]

[tex] \longmapsto \sf \red { x = 9 \: in} [/tex]

So, the value of x (perpendicular) is 9 in.

Answer:

y=45x+115

Step-by-step explanation:

We can find the slope of a line tangent to a curve at a point by evaluating the derivative of the function at that point.

We are given the function

f ( x ) = 4 x 3 + 12 x 2 + 9 x + 7

= f ( x ) = 4 x 3 + 12 x 2 + 9 x 1 + 7 x 0

Using the power rule, let's now compute the derivative of  f( x )

f ' ( x ) = ( 3 ⋅ 4 x 2 ) + ( 2 ⋅ 12 x ) + ( 1 ⋅ 9 x 0 ) + 0 ⋅ 7 x − 1

f ' ( x ) = 12 x 2 + 24 x + 9

We can now find the slope of  f ( x )  at  x = − 3  by substituting this value into f ' ( x )

f ' ( − 3 ) = 12 ( − 3 ) 2 + 24 ( − 3 ) + 9

f'(-3)=12(9)+24(-3)+9

f'(-3)=108-72+9

f'(-3)=45(slope of the tangent line at  x = − 3

Now that we have a slope for the tangent line, we need to identify a point on the line.

We know the tangent line touches the function  f ( x )  at the point  x = − 3 , so let's find the value of  f ( x )  at this point:

f(-3)=4(-3)3+12(-3)2+9(-3)+7

f(-3)=4(-27)+12(9)+9(-3)+7

f(-3)=108+108-27+7

f'(-3)=-20

So we know the tangent line goes through the point

(-3,-20)

Finally, we can use the point-slope formula for a line to find the equation of the tangent line.

y=mx+b

To find the value of  b , substitute the values we have calculated for the point and slope of the tangent line:

(-20)=(45)(-3)+b

-20=-135+b

b=115

So our final answer for the equation of the tangent line is:

y=45x+115

Answer:

θ = 0 to θ = 2π, r = 1 to r = -1 and z = 0 to z = 3

Step-by-step explanation:

Since the integration is in cylindrical coordinates, θ is integrated from 0 to 2π.

Since r = cosθ

when θ = 0, r = cos0 = 1

when θ = 2π, r = cos2π = -1

Since the region is bounded below by the plane z = 0, and on the top by the paraboloid z = 3r², z is integrated from z = 0 to z = 3r².

So, when r = 1, z = 3r² = 3(1)² = 3

when r = -1, z = 3r² = 3(-1)² = 3

So, the limits of integration of  

∭f(r,θ,z)dz r dr dθ are θ = 0 to θ = 2π, r = 1 to r = -1 and z = 0 to z = 3

Answer:

m= 2 43/63

Step-by-step explanation:

steps

6 1/9 = 3 3/7 + m

convert mixed numbers into improper fractions 6 1/9 = 55/9

55/9 = 3 3/7 + m

convert mixed numbers into improper fractions 3 3/7 = 24/7

55/9 = 24/7 + m

switch sides

24/7 + m = 55/9

subtract 24/7 from both sides

24/7 + m - 24/7 = 55/9 - 24/7

simplify

m = 169/63

convert improper fraction to mixed number

169/63 = 2 43/63

so your final answer is 2 43/63

Hope that helps!

Answer:

y = 2.5

Step-by-step explanation:

2(17y + 6) + 2(10y - 9) = 129

34y + 12 + 20y - 18 = 129

54y - 6 = 129

54y = 135

y = 2.5
