Answer 1

The rule of g(x) after the transformation is g(x) = 3(x + 4)^2 + 3(x + 4)

How to determine the image of the transformation?

The function is given as

f(x) = x^2 + x

The transformations are given as:

Translation 4 units leftHorizontal shrink by 1/3

The rule of the above transformations are :

Translation 4 units left: (x + 4, y)Horizontal shrink by 1/3: (3x, y)

When the above transformations are combined, we have

Translation 4 units left: (x + 4, y)Horizontal shrink by 1/3: (3(x + 4), y)

This means that

g(x) = 3f(x + 4)

So, we have

g(x) = 3(x + 4)^2 + 3(x + 4)

Hence, the function g(x) is g(x) = 3(x + 4)^2 + 3(x + 4)

Mark's soup recipe makes 10 servings and uses 4 carrots and 2 potatoes. Drag carrots and potatoes into the box to show how many Mark needs for 15 servings.

Answers

The number of carrots and potatoes that Mark will need for 3 servings will be 6 carrots and 3 potatoes.

How to illustrate the information?

It should be noted that an expression is simply used to show the relationship between the variables that are illustrated.

From the information, Mark's soup recipe makes 10 servings and uses 4 carrots and 2 potatoes. Therefore, to make 5 servings, he will need half of the carrots and potatoes. This will be 2 carrots and 1 potatoe.

Therefore, to make 15 servings, the total needed will be;

= (4 + 2 carrots) as (2 + 1 potatoes)

= 6 carrots and 3 potatoes

What are Tangents?

A line that only touches a circle or an ellipse at one point is said to be divergent in geometry. If a line contacts a curve at point P, that point is referred to as the point of tangency. In other words, it is described as the line that, at that particular location, indicates the slope of a curve. The following methods can be used to find the tangent equation in differential geometry:

As we are aware, the gradient of the curve at any given location on the curve is equal to the gradient of the tangent to the curve. The following is how to determine the tangent equation of the curve y = f(x):

Utilizing the differentiation principles, determine the gradient function's derivative.

To determine the tangent's gradient, the derivative should be changed to include the provided point's x-coordinate

Find the tangent equation by substituting the provided coordinate point and the gradient of the tangent into the straight-line equation (in a slope-point formula).

Circle's Tangent

A closed, two-dimensional form, a circle is also a curve. The radius of the circle or the line from the center O to the point of tangency is always vertical or perpendicular to the tangent line AB at P, i.e., OP is perpendicular to AB as illustrated in the accompanying picture.

Geometric Tangent

Here, "AB" stands for the tangent, "P" for the point of tangency, and "O" for the circle's center. The OP is the radius of the circle.

Answers

Answer:

2/5--1/4=3

Step-by-step explanation:

Answer is N = 20

Step by step

1/4 of a number means 1/4n
Is removed from is subtract
2/5 of that number means 2/5n
Result is 3 means equal = 3

Put this into an equation

2/5n - 1/4n = 3

Our common denominator is 20

2/5 = 8/20 ( multiplying top and bottom by 4)
1/4 = 5/20 (multiply top and bottom by 5)

8/20n - 5/20n = 3

Subtract

3/20n = 3

Divide both sides by 3/20 to solve for n
When we divide fractions we flip the divisor and multiply

3/20 * 20/3 n = 3 * 20/3

Multiply

among 6 electrical components exactly one is known not to function properly. if 4 components are randomly selected, find the probability that at least one does not function properly.

Answers

The probability that at least one electrical components does not function properly is 83.3%

What is defined as the probability?Probability is simply the likelihood of something occurring.When we are uncertain about the result of an event, we can discuss the probabilities of various outcomes—how probably they are.

To make the calculation easier, use the following property:

P(at the very least one) = 1 - P (None)

The total number of electrical components is 6.

Number that which not work well: 1

Number that works well: 5

We have options for selecting 4 good components from a set of 5 by;

⁵C₄  = 5

We have 4 options from a total of 6 components by;

⁶C₄ = 6

We have a way to do this if everything works properly; ¹C₀ = 1

P(at the very least one) = ⁵C₄× ¹C₀ /⁶C₄

P(at the very least one) = 5 / 6

P(at least one) = 0.833 = 83.3%

A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more numbers, or coordinates. The coordinates' order is important, and often they are recognised by their place in an ordered tuple or by a letter, as in "the x-coordinate." In elementary mathematics, the coordinates are assumed to be real numbers, although they could instead be complex numbers or components of a more abstract system, such a commutative ring.

Let the coordinate at point B be B( x,y )

given that 133 base n = 43base 10, find the value of n​

Answers

Answer:

n = 5

Step-by-step explanation:

Any 3-digit number to the base n will have its rightmost digit have a place value of n⁰, its next rightmost digit a place value of n¹ and the leftmost digit will have a place value of n²

This means 133can be represented as follows
n²     n¹     n⁰

1       3      3

The actual value in terms of a base of 10

= 3 x n⁰ + 3  x n¹   + 1 x n²

= 3 x 1 + 3 x n + 1 x n²      (n⁰ = 1 and n¹ = n)

= 3 + 3n + 1n²

Since we are given the information that 133ₙ = 43₁₀
3 + 3n + 1n²  = 43

subtract 3 from both sides
3n + 1n² = 40

Rewrite as

n² + 3n = 40

Factoring n on the left side=>
n(n + 3) = 40

If we look at the factors of 40:
1 x 40

2 x 20

4 x 10

5 x  8

5 and 8 satisfy the condition n(n + 3) = 40

So n = 5

Cauchy Goursat Theorem has been proved using Green's Theorem-

What is Green's Theorem, Cauchy Riemann Equation and Cauchy Goursat Theorem?

Green's Theorem

Let C be a positively oriented, piecewise smooth, simple closed curve in a plane, and let D be the region bounded by C. Then

Green's Theorem states that

[tex]\int_c (Mdx + Ndy)=\int_D(M_x - N_y)dxdy[/tex]

M and N are functions of x and y

Cauchy Goursat Theorem

If a function f is analytic at all points interior to and on a simple closed contour C, then

[tex]\int_c f(z) dz = 0[/tex]

Cauchy Riemann Equation

If [tex]f(z)=u(x,y) + i v(x,y)[/tex] is analytic at z = x + iy then Cauchy Riemann Equation states that

[tex]u_x = v_y, u_y = -v_x[/tex]

Here,

Let [tex]f(z) = U(x,y) + iV(x,y)[/tex]

[tex]U, V, x, y[/tex] are continuous

[tex]f(z)dz = (U + i V)(dx + i dy)[/tex]

[tex]f(z) dz = (U dx - Vdy)+i(Vdx + Udy)[/tex]

[tex]\int_c f(z) dz = \int_c(U dx - Vdy)+i\int_c(Vdx + Udy)[/tex], C is the curve

By Green's Theorem,

[tex]\int_c f(z)dz = \int_D(U_ydydx - V_xdxdy)+i\int_D(U_xdxdy + V_ydydx)[/tex], D is the surface

[tex]\int_c f(z)dz = \int_D(-U_y - V_x)dxdy+i\int_D(U_x - V_y)dxdy[/tex][tex]\int_c f(z)dz = \int_D(V_x - V_x)dxdy+i\int_D(U_x - U_x)dxdy[/tex]

Since [tex]f'[/tex] is continuous, [tex]f[/tex] is analytic

So [tex]f[/tex] satisfies Cauchy Riemann equation

[tex]U_x = V_y, U_y = -V_x[/tex]

So,

[tex]\int_c f(z)dz = \int_D(V_x - V_x)dxdy+i\int_D(U_x - U_x)dxdy[/tex]

[tex]\int_c f(z)dz = 0[/tex]

The computation shows that 1756.18595945 to the nearest hundred-thousandth will be 1756.18596.

How to illustrate the information?

After being rounded, the value of the hundred thousandth place, which is five places to the right of the decimal point, determines the value of the nearest ten thousandth of a decimal number, which is the value four places to the right of the decimal point.

The thousandth digit should be rounded down if the digit is less than 5. If that number is five or more, round it up to the nearest thousand. We must round up the thousandth digit because in the example given above, the digit following the thousandth digit (i.e., 9) is more than 5. This will give a value of 1756.18596.

there is no prior information about the proportion of americans who support free trade in 2018. if we want to estimate a 97.5% confidence interval for the true proportion of americans who support free trade in 2018 with a 0.16 margin of error, how many randomly selected americans must be surveyed? answer: (round up your answer to nearest whole number)

Answers

The number of randomly selected Americans that must be surveyed is equal to 38 if the confidence interval is 97.5% with a 0.16 margin of error.

First, we calculate the critical value as follows;

a = (1 - 0.975) = 0.025 = 0.025 / 2 = 0.0125 = (1 - 0.0125) = 0.9875

Z - Critical value = NORM.S.INV (0.9875) = 1.96

As margin of error(ME) = 0.16

Therefore;

n = pq(Z²) / ME²

n = 0.5 × 0.5 (1.96)² / (0.16)²

n = 0.25 × 3.8416 / 0.0256

n = 0.9604 / 0.0256

n = 37.515

Rounding it to the nearest whole number;

n = 37.515 = 38

Hence 38 randomly selected Americans must be surveyed if the estimated confidence interval is 97.5% and the margin of error is 0.16.

x-intercept:
y-intercept:
F41

Answers

Answer:

(-3/4, 0) and (0, 3/2)

Step-by-step explanation:

The [tex]x[/tex]-intercept is when [tex]y=0[/tex].

[tex]\frac{3}{4}+x=0 \implies x=-3/4[/tex]

So, the [tex]x[/tex] intercept has coordinates [tex](-3/4, 0)[/tex].

The [tex]y[/tex] intercept is when [tex]x=0[/tex].

[tex]\frac{3}{4}=\frac{1}{2}y \implies y=3/2[/tex].

So, the [tex]y[/tex] intercept has coordinates [tex](0, 3/2)[/tex]

What is an equation of the line that passes through the points (2, -8) and (1, -7)

Answers

For this equation, we need to find the slope and y-intercept in the following formula:

y = mx + b

(-7) - (-8) = 1

1 - 2 = -1

Our slope is -1/1, which converts to -x.

We can plug this in using any pair, but for this equation we’ll use the ordered pair (1, -7).

-7 = -1(1) + b

-7 = -1 + b

(-7) - (-1) = -6

b = -6

The equation of the line is:

y = -x - 6
