Answers

Answer 1

The slope of the line AB which passes through the points (4, 5) and B(9, 7) is 2/5.

According to the given question.

We have a line AB containing the points A(4, 5) and B(9, 7).

Here, we have to find the slope of line AB.

As we know that, as we know that, the slope of a line is the ratio of the amount that y increases as x increases some amount.And the slope formula is m=(y2-y1)/(x2-x1) if a lines passes through the point (x2, y2) and (x1, y1).

Therefore, the slope of the line AB which passes through the points (4, 5) and B(9, 7)

= (7 - 5)/(9 - 4)

= 2/5

Hence, the slope of the line AB which passes through the points (4, 5) and B(9, 7) is 2/5.

If K is the midpoint of JL, JK = 8x +11 and KL = 14x - 1, find JL

Answers

Given a line k is between J and L from J-K the line is 8x+11 and from K-L its 14x-1. So first youre going to have to solve for X
Since K is the midpoint both equations are equal to eachother so the first equation is

8x+11=14x-1
-6x+11=-1
-6x=-12
x=2

Now since we have x we can solve so youre going to put x into one of the equations. It doesnt matter which once cause they are both equal. So we can do 8x+11
8(2)+11
16+11
27
So now we have 27 we can add both together since 27=27
So you have JL=54 un
Use un if you dont have a distance

We are given that:

The relationship between x and y

We need to find  the dog food for the 25-pound adult dog

The weight of the adult dog (X) is proportional to the amount of dog food in cups are proportional.

x = k y

k = x / y

k = 10 / 1/6

k = 10 (6)

k = 60

Let the dog food recommended for the 25-pound adult dog be y.

Weight of the dog = x = 25 pounds

Cups of dog food recommended = y

k = 60

Using the equation for the given relationship:

25 = 60 × y

y = 25 / 60

y = 5 / 12

Therefore, 5/12 cups of dog food are recommended for a 25-pound adult dog by using the proportion.

the scalar product between two vectors involves which function of the angle between the lines of action of the two vectors

Answers

The scalar product between two vectors involves the cosine function of the angle between the lines of action of the two vectors.

What is the scalar product?

The dot product, also known as the scalar product, is an algebraic operation that takes two sequences of numbers of equal length (often coordinate vectors) and outputs a single number. The dot product of two vectors' Cartesian coordinates is frequently used in Euclidean geometry. Although other inner products can be defined in Euclidean space, it is frequently referred to as the inner product (or, less frequently, projection product) of Euclidean space (see Inner product space for more). The sum of the products of the matching entries of the two number sequences is the dot product, according to algebra. Geometrically, it is the result of adding the cosine of the angle between the two vectors and the Euclidean magnitudes of the two vectors.

Answers

(a)

a. The common ratio is -2.

b. The first term is 7

c. The sum of the GP is -147

What is the common ratio?

(a) To find the common ratio (r), we can use the formula for the nth term of a geometric progression (G.P):

[tex]A_n = A_1 * r^(^n^-^1^)[/tex],

where Aₙ is the nth term, A₁ is the first term, r is the common ratio, and n is the term number.

Given that the 3rd term (A₃) is 28 and the 4th term (A₄) is -56, we can set up two equations using the formula above:

[tex]28 = A_1 * r^(^3^-^1^)[/tex],     (Equation 1)

[tex]-56 = A_1 * r^(^4^-^1^)[/tex].     (Equation 2)

Dividing Equation 2 by Equation 1, we get:

[tex]-56/28 = (A_1 * r^(^4^-^1^)^) / (A_1 * r^(^3^-^1^))\\-2 = r.[/tex]

Therefore, the common ratio (r) is -2.

(b) To find the first term (A1), we can substitute the known values into one of the equations. Let's use Equation 1:

[tex]28 = A_1 * (-2)^(^3^-^1^)\\28 = A_1 * (-2)^2\\28 = A_1 * 4\\A_1 = 7[/tex]

Therefore, the first term (A₁) is 7.

(c) To find the sum of the geometric progression, we can use the formula for the sum of the first n terms of a geometric progression:

[tex]S_n = (A_1 * (1 - r^n)) / (1 - r)[/tex],

where Sₙ is the sum of the first n terms.

Given that there are 6 terms (n = 6), A₁ = 7, and r = -2, we can calculate the sum (S₆):

[tex]S_6 = (7 * (1 - (-2)^6)) / (1 - (-2)).[/tex]

Simplifying:

S₆= (7 * (1 - 64)) / (1 + 2),

S₆ = (7 * (-63)) / 3,

S₆ = -147.

Therefore, the sum of the geometric progression is -147.

The inverse of a trigonometric function, the inverse of a rational function, the inverse of a hyperbolic function, and the inverse of a log function are just a few examples of the various types of inverse functions.

Substituting f(x) with y

f(x)=1/9x+2
