Patricia bought 4 apples and 9 bananas for $12. 70. Jose bought 8 apples and 11 bananas for $17. 70 at the same grocery store. What's the price of one apple?

Answers

Answer 1

the price of one apple after solving the simultaneous equations is $1.45.

Let's denote the price of one apple by "a" and the price of one banana by "b". We can then set up a system of two equations to represent the given information:

4a + 9b = 12.70 (equation 1)
8a + 11b = 17.70 (equation 2)

To solve for the price of one apple, we want to isolate "a" in one of the equations. One way to do this is to multiply equation 1 by 8 and equation 2 by -4, which will allow us to eliminate "b" when we add the two equations together:

(8)(4a + 9b) = (8)(12.70) --> 32a + 72b = 101.60 (equation 3)
(-4)(8a + 11b) = (-4)(17.70) --> -32a - 44b = -70.80 (equation 4)

Adding equations 3 and 4 gives:

28b = 30.80

Solving for "b" yields:

b = 1.10

Substituting this value of "b" into equation 1 gives:

4a + 9(1.10) = 12.70

Solving for "a" yields:

a = 1.45

Therefore, the price of one apple is $1.45.

what is the slope of the line that passes through the point (-1,-10) and (-1,-2). answer needs to be in simplest form

Answers

Answer: m = undefined

Step-by-step explanation:

-2-(-10) = 8

-1-(-1) = 0

m = 8/0

Which is an undefined slope

Answer:

The slope is undefined

Step-by-step explanation:

Plug in the points to the formula for slope (Formula Found Below). You would get (-2 + 10)/(-1 + 1), which simplifies to 8/0. Anything divided by 0 is undefined, which means that the slope is undefined.

Furthermore, you could also tell this simply by the points given. If two points on a line have the same x - coordinate, it means that the slope is undefined and that the line formed by the points isn't a function.

Formula for Slope:

\(\frac{y1 - y2}{x1 - x2}\)

Usable with 2 points of the line given ((x1, y1) and (x2, y2))

A line includes the points (6,10) and (1,0) What is its equation in slope-intercept form?

Answers

Answer:

The slope-intercept is \(y = 2x -2\) .

Step-by-step explanation:

-First, you need to find the slope by using the slope formula:

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

-Second, use both points (6, 10) and (1, 0) for the formula:

\(m =\frac{0-10}{1-6}\)

-Third, you solve:

\(m =\frac{0-10}{1-6}\)

\(m = 2\)

-Fourth, after you found the slope, you need to use the Point-slope form equation:

\(y - y_{1} = m (x -x_{1})\)  (where \(m\) represents the slope, and \((x_{1},y_{1})\) represents the first coordinate or the first point).

-Fifth, use the slope 2 and the first point (6, 10) for the Point-slope form equation:

\(y - 10= 2 (x -6)\)

-Sixth, you solve the equation to get the slope-intercept form:

\(y - 10= 2 (x -6)\)

\(y -10 = 2x -12\)

\(y -10 +10 = 2x -12 +10\)

\(y = 2x -2\)

So, therefore, the slope-intercept is \(y = 2x -2\) .

Consider the function f(x,y,z)=5+yxz​+g(x,z) where g is a real-valued differentiable function. Find the directional derivative of f at the point (3,0,3) along the direction of the vector (0,4,0). Enter your answer symbolically, as in these

Answers

Given, the function is f(x,y,z)=5+yxz+g(x,z)Here, we need to find the directional derivative of f at the point (3,0,3) along the direction of the vector (0,4,0) . The directional derivative of f at the point (3,0,3) along the direction of the vector (0,4,0) is 0.

Using the formula of the directional derivative, the directional derivative of f at the point (3,0,3) along the direction of the vector (0,4,0) is given by

(f(x,y,z)) = grad(f(x,y,z)).v

where grad(f(x,y,z)) is the gradient of the function f(x,y,z) and v is the direction vector.

∴ grad(f(x,y,z)) = (fx, fy, fz)

                       = (∂f/∂x, ∂f/∂y, ∂f/∂z)

Hence, fx = ∂f/∂x = 0 + yzg′(x,z)fy

                = ∂f/∂y

                = xz and

fz = ∂f/∂z = yx + g′(x,z)

We need to evaluate the gradient at the point (3,0,3), then

we have:fx(3,0,3) = yzg′(3,3)fy(3,0,3)

                             = 3(0) = 0fz(3,0,3)

                             = 0 + g′(3,3)

                             = g′(3,3)

Therefore, grad(f(x,y,z))(3,0,3) = (0, 0, g′(3,3))Dv(f(x,y,z))(3,0,3)

                                                 = grad(f(x,y,z))(3,0,3)⋅v

where, v = (0,4,0)Thus, Dv(f(x,y,z))(3,0,3) = (0, 0, g′(3,3))⋅(0,4,0)   = 0

The directional derivative of f at the point (3,0,3) along the direction of the vector (0,4,0) is 0.

π is the circumference of a circle of diameter 1.

π is the constant of proportionality relating the diameter of a circle to its circumference.

What is a circle?

A circle is a two-dimensional figure with a radius and circumference of 2 x pi x r.

The area of a circle is given as:

We have,

Circumference of a circle = 2πr

Area of a circle = πr²

π is the area of a circle of radius 1.

Area = πr² = π x 1 = π

π is the area of diameter 1.

2r = 1

r = 1/2

Area = πr² = π x 1/4 = π/4

π is the circumference of a circle of radius 1.

Circumference of a circle = 2πr = 2 x π x 1 = 2π.

π is the circumference of a circle of diameter 1.

Circumference of a circle = 2πr = 2 x π x 1/2 = π.

π is the constant of proportionality relating the diameter of a circle to its circumference.

Diameter ∝ Circumference

2r = 2πr

2r = π (2r)

π is the constant of proportionality relating the radius of a circle to its area.

r = (πr)r

Thus,

what is the general term of the sequence: 7; 2;-3 ; -8

Answers

To find the general term of a sequence, we need to identify the pattern or rule that governs the sequence. In this case, we can observe that each term in the sequence is decreasing by 5.

Starting with the first term, 7, and subtracting 5 repeatedly, we can generate the following terms:
7, 7 - 5 = 2, 2 - 5 = -3, -3 - 5 = -8, and so on.

The pattern is that each term is obtained by subtracting 5 from the previous term.

Therefore, we can express the general term of the sequence as:

a_n = 7 - 5n,

where n represents the position of the term in the sequence, starting from n = 1 for the first term.

Therefore, the expression is undefined when the value of x = 7 or x = -3.

What is equation?

An equation is a mathematical statement that asserts the equality of two expressions. It typically involves one or more variables and can be written using mathematical symbols such as addition, subtraction, multiplication, division, exponents, and roots. The goal of solving an equation is to find the values of the variables that satisfy the equation.

Here,

To simplify the expression, we first factor the denominator:

x² - 4x - 21 = (x - 7)(x + 3)

Now, we can rewrite the expression as:

(12x + 36) / (x - 7)(x + 3)

We can simplify the numerator by factoring out 12:

12(x + 3) / (x - 7)(x + 3)

The (x + 3) terms cancel out, leaving:

12 / (x - 7)

So the simplified expression is 12 / (x - 7).

The restrictions on the variable come from the fact that the denominator cannot be equal to zero. So we set the denominator equal to zero and solve for x:

(x - 7)(x + 3) = 0

x = 7 or x = -3

The poem For Want of a Nail is a warning about how small things can have large and unforeseen consequences. The lack of a horseshoe could lead to the loss of a horse, which could result in the loss of a rider, which could lead to the loss of a battle.

This shows that a small change can cause a big difference in the outcome. We can see a similar phenomenon in the world of mathematics, where small changes in a function can lead to significant changes in its behavior. For example, the degree of a polynomial can have a dramatic effect on its graph. Let's consider the function y = x². This is a second-degree polynomial, which means that its graph is a parabola. If we change the degree of this polynomial to 1, then we get the function y = x, which is a straight line. If we change the degree of this polynomial to 3, then we get the function y = x³, which is a cubic curve. If we graph these functions for the values of x from -3 to 3, we can see how the slight change in the degree of the polynomial affects their graphs. The graph of y = x² is a parabola that opens upward. TThe graph of y = x is a straight line that passes through the origin. The graph of y = x³ is a cubic curve that passes through the origin and has two turning points. These graphs show that a small change in the degree of the polynomial can have a significant effect on its graph.

If seven people are randomly selected from the spectators during a football match, What is the probability that 4 of them are males? (3 marks) i 11. Find the probability that at most 5 of them are females (4 marks)

Answers

a) The probability of randomly selecting 4 males out of 7 spectators, given that 70% of the spectators are males, can be calculated using the binomial probability formula.

b) To find the probability that at most 5 of the randomly selected spectators are females, we need to calculate the cumulative probability of selecting 0, 1, 2, 3, 4, and 5 females from the total number of selected spectators.

a) To calculate the probability of selecting 4 males out of 7 spectators, we can use the binomial probability formula:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

Where:

- n is the total number of trials (number of people selected)

- k is the number of successful trials (number of males selected)

- p is the probability of success in a single trial (probability of selecting a male)

- C(n, k) is the binomial coefficient, calculated as C(n, k) = n! / (k! * (n - k)!)

In this case, n = 7, k = 4, and p = 0.70 (probability of selecting a male). Therefore, the probability of selecting 4 males out of 7 spectators is:

P(X = 4) = C(7, 4) * (0.70)^4 * (1 - 0.70)^(7 - 4)

b) To find the probability that at most 5 of the selected spectators are females, we need to calculate the cumulative probability of selecting 0, 1, 2, 3, 4, and 5 females. This can be done by summing the individual probabilities for each case.

P(X ≤ 5 females) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)

To calculate each individual probability, we use the same binomial probability formula as in part a), with p = 0.30 (probability of selecting a female).

Finally, we sum up the probabilities for each case to find the probability that at most 5 of the selected spectators are females.
