Answer:

y = 5x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (2, 9)

m = \(\frac{9-4}{2-1}\) = \(\frac{5}{1}\) = 5 , then

y = 5x + c ← is the partial equation

To find c use any ordered pair from the table and substitute into the partial equation.

Using (3, 14 ) , then

14 = 15 + c ⇒ c = 14 - 15 = - 1

y = 5x - 1 ← equation of line

The balance in the account after 5 years is $10750.

The following can be deduced based on the information given:

Principal = $10000

Rate = 1.5%

Time = 5 years..

Interest = (Principal × Rate × Time) / 100

= (10000 × 1.5 × 5) / 100

= $750

The balance will be:

= Principal + Interest

= $10000 + $750

= $10750

If the shaded area of a circle is 25 cm squared. if the diameter of the circle is 10cm, the percentage of the circle is shaded is: 31.83% .

We can start by finding the area of the entire circle. The formula for the area of a circle is:

A = πr^2

where A is the area and r is the radius. Since the diameter of the circle is 10 cm, the radius is half of that, or 5 cm. Therefore, the area of the entire circle is:

A = π(5 cm)^2 = 25π cm^2

Next, we can find what percentage of the circle is shaded by dividing the shaded area by the total area of the circle and multiplying by 100:

Percentage shaded = (shaded area / total area) x 100

Percentage shaded = (25 cm^2 / 25π cm^2) x 100

Percentage shaded = 100 / π ≈ 31.83%

Therefore, approximately 31.83% of the circle is shaded.

Distance is increasing with a speed of 0.2 Miles/Min

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

OB

because domain is all X values that satisfy graph. And on graph X has all +ve values going to infinity.

When the Function g is defined as g(x) = 2f(x – 4) + 3 so the domain of the function g is OB. {x|0 < x <♾}.

Since the Function g is defined as g(x) = 2f(x – 4) + 3

So here OB should be considered as the domain of the all x values should satisfied the graph. Also, on graph X it contains the positive values that goes to infinity.

The equation of an exponential function is y = a(b^x)

An exponential function is a mathematical function that has a constant base raised to a variable exponent.  Exponential functions are used to model processes that exhibit exponential growth or decay, such as population growth, radioactive decay, or the spread of infectious diseases.

The general form of an exponential function is:

f(x) = ab^x

where a is the initial value, b is the base, and x is the variable exponent. If the base is greater than 1, the function will exhibit exponential growth, while if the base is between 0 and 1, the function will exhibit exponential decay.

The length of the solenoid is 4 cm, the number of coils is 400, and the area of each loop is 3 cm^2. The area per unit length of the solenoid is A/l = 3/4 = 0.75 cm^2/cm.

The inductance of a solenoid of length 4 cm with 400 coils is given by the formula L = μ0n^2A/l, where n is the number of turns per unit length of the solenoid, A is the area of each loop, l is the length of the solenoid, and μ0 is the permeability of free space, which is equal to \(4π × 10^-7 T·m/A.\)

The number of turns per unit length of the solenoid is n = N/l = 400/4 = 100 turns/cm.

So, the inductance of the solenoid is
\(L = μ0n^2A/l = 4π × 10^-7 × 100^2 × 0.75 × 10^-4/4 = 2.355 × 10^-5 H.\)

The current flowing in the solenoid is given by I = (0.4 A) cos (2π60t/s). The witage across the inductor is given by the formula V = L(dI/dt). So, differentiating I with respect to t, we get

\(dI/dt = - 0.4 A × 2π60 sin (2π60t/s) = - 4.776π sin (2π60t/s)\).

\(V = L(dI/dt) = - 2.355 × 10^-5 × 4.776π sin (2π60t/s) = - 0.283 sin (2π60t/s) V.\)

a) To prove this, it needs to satisfies the Closure under addition, Closure under multiplication by elements of R and Contains the kernel of f properties. b) To prove this, it needs to satisfies the Closure under addition, Closure under multiplication by elements of S and Contains 0.

(a) Proof that \(f^{-1}\) (J) is an ideal in R containing the kernel of f:

To show that  \(f^{-1}\) (J) is an ideal in R, we need to demonstrate that it satisfies the following properties:

Closure under addition,

Let a, b be elements in  \(f^{-1}\) (J) and let r be any element in R. We have f(a), f(b) in J since J is an ideal of S. Since f is a homomorphism of rings, f(a + b) = f(a) + f(b) is in J. Therefore, a + b is in  \(f^{-1}\) (J), showing closure under addition.

Closure under multiplication by elements of R,

Let a be an element in  \(f^{-1}\)  (J) and let r be any element in R. We have f(a) in J since J is an ideal of S. Since f is a homomorphism of rings, f(ra) = rf(a) is in J. Therefore, ra is in  \(f^{-1}\) (J), showing closure under multiplication by elements of R.

Contains the kernel of f,

Let x be an element in the kernel of f, i.e., f(x) = 0 in S. Since J is an ideal of S, 0 is in J. Therefore, x is in  \(f^{-1}\) (J), showing that  \(f^{-1}\) (J) contains the kernel of f.

Therefore,  \(f^{-1}\)  (J) is an ideal in R that contains the kernel of f.

(b) Proof that if f is an epimorphism, then f(I) is an ideal in S:

To show that f(I) is an ideal in S, we need to demonstrate that it satisfies the following properties:

Closure under addition,

Let a, b be elements in f(I), and let s be any element in S. Since f is surjective, there exist elements x, y in I such that f(x) = a and f(y) = b. Therefore, f(x + y) = f(x) + f(y) = a + b is in f(I), showing closure under addition.

Closure under multiplication by elements of S,

Let a be an element in f(I), and let s be any element in S. Since f is surjective, there exists an element x in I such that f(x) = a. Therefore, f(sx) = sf(x) = sa is in f(I), showing closure under multiplication by elements of S.

Contains 0,

Since f is a homomorphism of rings, f(0) = 0 in S. Therefore, 0 is in f(I).

Therefore, if f is an epimorphism, f(I) satisfies the properties of an ideal in S.

If f is not surjective, f(I) need not be an ideal in S. This is because in this case, there may exist elements in S that are not in the image of f, and therefore f(I) may not satisfy the closure properties required for an ideal.
