Answer:

25

Step-by-step explanation:

To find the value of a number given that 12% of it is 150, we can set up the following equation:

0.12x = 150

Solving for x, we get:

x = 150 / 0.12 = 1250

To find 2% of that number, we simply multiply 1250 by 0.02:

2% of 1250 = 0.02 * 1250 = 25.

Therefore, 2% of the number for which 12% is 150 is 25.

The amount of butter that is used this month will be 320 kilograms.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

A pastry shop utilized 25% less spread for the current month than a month ago. The pastry shop utilized 240 kilograms of spread for the current month.

Let 'x' be the amount of butter used in the last month. Then the equation is given as,

(1 - 0.25) x = 240

Simplify the equation, then we have

(1 - 0.25) x = 240

0.75x = 240

x = 240 / 0.75

x = 320 kilograms

The amount of butter that is used this month will be 320 kilograms.

Answer:

n = -8 , n = -12

Step-by-step explanation:

First we factorise the quadratic using the factorisation method :

n²+8n+12n+96 = 0

n(n+8)+12(n+8) = 0

(n+12)(n+8) = 0

Now we equate each bracket to 0 :

Either

n + 12 = 0  

n = -12

OR

n + 8 = 0

n = -8

So the real solutions for that equation is

n = -8 , n = -12

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

Given two points, the slope is given by the change in y divided by the change in x, hence the slope of segment RS is given as follows:

m = (16 - 4)/(9 - 3) = 2.

When two lines are perpendicular, the multiplication of their slopes is of -1, hence the slope of the perpendicular bisector is obtained as follows:

2m = -1

m = -1/2.

The midpoint of a segment is given by the mean of the coordinates, hence:

The perpendicular bisector is a linear function with slope of -1/2 going through the point (6,10), hence the intercept b is calculated as follows:

10 = -0.5(6) + b

Answer:

The slope is 3/8

Step-by-step explanation:

The slope of the line given by the equation 3x - 8y = -16 is 3/8.

To find the slope of the line given by the equation 3x - 8y = -16, we need to rearrange the equation into slope-intercept form, y = mx + b, where m represents the slope.

Starting with the given equation:

3x - 8y = -16

We can isolate y by subtracting 3x from both sides:

-8y = -3x - 16

Next, we divide both sides of the equation by -8 to solve for y:

y = (3/8)x + 2

Now, we can observe that the equation is in slope-intercept form, y = mx + b, with m = 3/8.

This means that for every increase of 1 in the x-coordinate, the y-coordinate increases by 3/8.

The lengths of the edges of the considered rectangular box which will give the minimum surface area are all ∛34.

How to find the surface area and volume of a closed rectangular box?

Suppose the dimensions of the rectangular box be 'a', 'b' and 'c' units respectively. Then, we get:

Surface area of the box, S = 2(ab + bc + ca) unit²

Volume of the box, V = abc unit³

For the considered box, let the dimensions be 'a', 'b' and 'c' cm.

Then, as we're provided that the volume of the box is 34 cubic cm, we get:

abc = 34

c = 34/ab

Thus, the surface area of the considered figure would be given as:

S = 2(ab + bc + ca) unit²

S = 2(ab+ c(b+a))

= 2(ab+ (34/ab) (b+a))

=( 2a²b² + 68b + 68a)/ ab cm²

There is symmetry in the equation we obtained for surface area between 'a' and 'b'.

That means, they will be of same measure to minimize or maximize the surface area. It is because if one of them is bigger than other, it is possible to prove that other one, by same tricks, can be proved bigger than first one.

Thus, we have a = b for S to be maximum or minimum.

Thus, we get:

Smax or min = (2a⁴+136a) / a²

= (2a²+ 136) / a

= f(a)

Taking first derivative of f(a), we get:

f'(a) = 4a - 136 / a²

f''(a) = 4 + 272/a³

Putting second rate = 0, we get critical points as:

f'(a) = 0

4a = 136/ a²

a³ = 34

a = ∛34 = b

Thus, the only critical value found is corresponding to minima.

Thus, S is minimum when a = b = ∛34

The value of c is:

c = 34/ab

= 34/ [tex]\sqrt[3]{34^{2} }[/tex]

= (34)¹/³

c = ∛34

Thus, the lengths of the edges of the considered rectangular box which will give the minimum surface area are all ∛34.

The slope of the tangent line to the given polar curve at the point specified by the value of theta is m= 1/√3.

A straight line that just touches a plane curve at a particular location is referred to as the tangent line (or tangent) to the curve in geometry. It was described by Leibniz as the line connecting two points on the curve that are endlessly near to one another. A line passes through the point (c, f(c)) on the curve and has a slope of f'(c), where f' is the derivative of f. This is more properly referred to as being a tangent of the curve y = f(x) at a point x = c. Curves in n-dimensional Euclidean space and curves in space have a comparable definition.

The tangent line is "passing" through the point of tangency—the intersection of the tangent line and the curve as it travels.

Given,

r=6cosθ

f'(θ)=-6sinθ

θ=π/3

dy/dx=(f'(θ)sinθ+f(θ)cosθ)/(f'(θ)cosθ-f(θ)sinθ)

dy/dx=( -6sinθsinθ+6cosθcosθ)/(-6sinθcosθ-6cosθsinθ)

=(6cos²θ-6sin²θ)/-12 sinθcosθ

=6(cos²θ-sin²θ)/-6(2sinθcosθ)

=6cos2θ/-6sin2θ

=-cos2θ/sin2θ

=-cot2θ

Slope of the given polar curve at θ=π/3 is

m=dy/dx

m= -cot(2(π/3))

m = cot(-2π/3)

The exponential growth model below that fits the points (0, 2720) and (8, 10,225) as  [tex]y = 2720 \times0.039^t.[/tex]

To find the exponential growth model that fits the points (0, 2720) and (8, 10,225), we need to find the values of the constants k and y0 in the equation [tex]y = y_0e^(kx)[/tex]. We can do this by substituting the coordinates of the two points into the equation and solving for the constants.

First, we substitute the coordinates of the first point into the equation:

[tex]2720 = y_0e^(k\times0)[/tex]

We can simplify this expression by substituting 1 for e⁰: 2720 = y⁰ˣ¹

This equation tells us that y0 = 2720.

Next, we substitute the coordinates of the second point into the equation: [tex]10,225 = y_0e^(k\times8)[/tex]

Substituting the value of y0 that we found above, we get: [tex]10,225 = 2720e^(k\times8)[/tex]

To solve for k, we divide both sides of the equation by 2720: [tex]\dfrac {10,225}{2720} = e^(k\times8)[/tex]

We can take the natural logarithm of both sides to get: ln(10,225/2720) = k8

Dividing both sides of the equation by 8, we get: k = ln(10,225/2720)/8

We can approximate the value of k by using a calculator to evaluate the logarithm: k ≈ 0.039

We now have the values of the constants k and y0, so we can write the exponential growth model that fits the given points: [tex]y = 2720 \times0.039^t.[/tex]

This is the exponential growth model that fits the points (0, 2720) and (8, 10,225).

The slope of a line parallel to 1 2 is also 1 2. The equation for a line parallel to the line with equation y = mx + b is y = mx + b + c, where c is any constant.

The slope of a line parallel to 1 2 is the same as the slope of 1 2, which is 1 2.

The slope of a line is calculated by dividing the change in the y-values by the change in the x-values. In the case of 1 2, this is (2-1)/(2-1), which equals 1/1, or 1 2. So the slope of any line parallel to 1 2 is also 1 2. Parallel slope intercept form is a form of linear equation that describes a line parallel to a given line. It is written as y = mx + b, where m is the slope of the line and b is the y-intercept of the line. This form is useful for finding equations of lines that are parallel to a given line.

x - 3 = [tex]\sqrt{11}[/tex]

Square both,

[tex](x - 3)^{2}[/tex] = 11

[tex](x - 3)^{2}[/tex] - 11 =0

Now we will use the principle of Square difference to factorize both sides-

[tex](d^{2} - e^{2}) = (d - e)(d + e)[/tex]

(x - 3) - 11 × (x - 3) + 11 = 0

on solving the equation we get,

(x - 3) - 1 = 0  let us consider this first equation

or (x - 3) + 11 = 0 let us consider this second equation

Add [tex]\sqrt{11}[/tex] on both sides of the first equation,

[tex]x - 3 = \sqrt{11}[/tex]

Subtract [tex]\sqrt{11}[/tex] on both sides of the second equation,

[tex]x - 3 = -\sqrt{11}[/tex]

Now by adding 3 on both sides of the first and second equation,
