Answer: 8 cups of orange juice concentrate

Step-by-step explanation:

Since the ratio of cups of orange juice concentrate to water in a punch recipe is 1 : 4. It simply means that for 1 cup of orange juice, there are 4 cups of water.

Therefore, if Gordon used 32 cups of water, the number of cups of orange juice concentrate that he used will be one quarter of 32. This will be:

= 1/4 × 32

= 8 cups of orange juice concentrate

The probability P(n < 10 | n is prime) is 4/6, which simplifies to 2/3 or approximately 0.67 (rounded to the nearest hundredth).

To find the probability P(n < 10 | n is prime), we need to determine the number of prime integers less than 10 and divide it by the total number of integers from 1 to 15 that are prime.

The prime numbers less than 10 are 2, 3, 5, and 7. So, there are 4 prime numbers less than 10.

The total number of integers from 1 to 15 that are prime is 6 (2, 3, 5, 7, 11, and 13).

As a result, the chance P(n 10 | n is prime) is 4/6, which can be expressed as 2/3 or, rounded to the nearest hundredth, as around 0.67.

Thus, 0.67 is the answer.

The top of the ladder touches the wall at 9 ft above the ground.

We are given that;

Measurements= 15ft and 12ft

Now,

To find the height of the ladder on the wall, we can use the Pythagorean theorem. The ladder, the wall, and the ground form a right triangle, where the ladder is the hypotenuse and the wall and the ground are the legs. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the legs. Using this theorem, we get:

h^2 + 12^2 = 15^2 h^2 + 144 = 225 h^2 =225 - 144 h^2= 81 h=sqrt(81) h= 9

Answer:

Step-by-step explanation:

Parallel line have the same slope.  Put the reference line is y=mx+b format.  m will be the slope.  A parallel line must have the same m.  Example:

y=2x+5 has a slope of 2 and a y-intercept of 5 (the value of y when x is 0).  Any line witrh the same slope will be parallel.  So with can write y=2x+b, where we'll change the y-interecpt so the the lines don't overlap.  Once we know the parallel line must be y = 2x+b, we can enter the known point, e.g., (3,14), and calculate b:

y=2x+b

14=2*3+b

14=6+b

b=8

The parallel line to y=2x+5 is y=2x+8:  It is parallel and goes through the point (3,14).

The correct ratio to be able to find x would be B. tan ( x ) = 1 / 2.

In the right angled triangle given, the value of x is an angle and we are given the dimensions that are opposite that angle and adjacent to it. This means that the best operation would be tangent.

The value of x is therefore :

Tan ( angle ) = Opposite / Adjacent

Opposite = 5

Adjacent = 10

(c) y=-9x    YES

(d) y=-x+3  YES

See attached graph.

Answer:

A = NO

B = NO

C = YES

D = YES

Step-by-step explanation:

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables.

For A: The degree of variable y is 1 and the degree of variable x is 2.

So it is not linear.

For C: The degree of variable y is 1 and the degree of variable x is 1.

So it is linear.

If the force is changed to 50N, the acceleration of the object becomes 10m/s²

From the information given, we have that force is directly varies as the acceleration.

Given that;

This is represented as;

F ∝ a

Then, the constant is

F= ka

Now, make 'k' the subject of the formula, we get;

k = F/a

substitute the values to determine the value of k

k = 40/8 = 5

If the value of the force, F of the object changes to 50N, then the acceleration is given as;

a = F/k

Substitute the values into the formula

a = 50/5

Divide the values

a = 10m/s²

Hence, the value is a = 10m/s²

The diver take her at a distance of 9.2 meters.

A resultant displacement can be used to quantify distance. It involves measuring the coordinate values of the beginning and ending positions. The distance is measured in quantities like meters, centimeters, kilometers, etc.

A diver descends 1.7 meters below the surface of the water while suspended 7.5 meters above it, according to the question.

According to fundamental mathematics, values that are less than zero can be represented as negative values.

She will thus descend (-1.7) meters as she dives below the surface.

The formula may now be expressed as follows: Total Distance = 7.5 - (-1.7) = 9.2 meters.

As a result, the diver descends 9.2 meters below the surface with her.

To evaluate c ∇f · dr, we need to first find the gradient vector ∇f and the differential vector dr.

Since the function f is not given, we cannot find ∇f explicitly. However, we know that ∇f points in the direction of greatest increase of f, and that its magnitude is the rate of change of f in that direction. Therefore, we can make an educated guess about the form of ∇f based on the information given.

The function f could be any function, but let's assume that it is a function of two variables x and y. Then, we have:

∇f = (∂f/∂x, ∂f/∂y)

where ∂f/∂x is the partial derivative of f with respect to x, and ∂f/∂y is the partial derivative of f with respect to y.

Now, let's find the differential vector dr. The parameterization of c is given by:

x = t^2 + 1

y = t^3 + t

0 ≤ t ≤ 1

Taking the differentials of x and y, we get:

dx = 2t dt

dy = 3t^2 + 1 dt

Therefore, the differential vector dr is given by:

dr = (dx, dy) = (2t dt, 3t^2 + 1 dt)

Now, we can evaluate c ∇f · dr as follows:

c ∇f · dr = (c1 ∂f/∂x + c2 ∂f/∂y) (dx/dt, dy/dt)

where c1 and c2 are the coefficients of x and y in the parameterization of c, respectively. In this case, we have:

c1 = 2t

c2 = 3t^2 + 1

Substituting these values, we get:

c ∇f · dr = (2t ∂f/∂x + (3t^2 + 1) ∂f/∂y) (2t dt, 3t^2 + 1 dt)

Now, we need to make an educated guess about the form of f based on the information given. We know that f is a function of x and y, and we could assume that it is a polynomial of some degree. Let's assume that:

f(x, y) = ax^2 + by^3 + cxy + d

where a, b, c, and d are constants to be determined. Then, we have:

∂f/∂x = 2ax + cy

∂f/∂y = 3by^2 + cx

Substituting these values, we get:

c ∇f · dr = [(4at^3 + c(3t^2 + 1)t) dt] + [(9bt^4 + c(2t)(t^3 + t)) dt]

Integrating with respect to t from 0 to 1, we get:

c ∇f · dr = [(4a/4 + c/2) - (a/2)] + [(9b/5 + c/2) - (9b/5)]

Simplifying, we get:

c ∇f · dr = -a/2 + 2c/5

Therefore, the value of c ∇f · dr depends on the constants a and c, which we cannot determine without more information about the function f.

The value of c where c has parametric equations x = t2 + 1, y = t3 + t, 0 t 1. is  c ∇f · dr=  [(2t^5 + 2t^3)(∂f/∂x) + (9t^7 + 3t^5)(∂f/∂y)] dt.

We have the following information:

c(t) = (t^2 + 1)i + (t^3 + t)j, 0 ≤ t ≤ 1

f(x, y) is a scalar function of two variables

We need to find c ∇f · dr.

We start by finding the gradient of f:

∇f = (∂f/∂x)i + (∂f/∂y)j

Then, we evaluate ∇f at the point (x, y) = (t^2 + 1, t^3 + t):

∇f(x, y) = (∂f/∂x)(t^2 + 1)i + (∂f/∂y)(t^3 + t)j

Next, we need to find the differential vector dr = dx i + dy j:

dx = dx/dt dt = 2t dt

dy = dy/dt dt = (3t^2 + 1) dt

dr = (2t)i + (3t^2 + 1)j dt

Now, we can evaluate c ∇f · dr:

c ∇f · dr = [c(t^2 + 1)i + c(t^3 + t)j] · [(∂f/∂x)(2t)i + (∂f/∂y)(3t^2 + 1)j] dt

= [c(t^2 + 1)(∂f/∂x)(2t) + c(t^3 + t)(∂f/∂y)(3t^2 + 1)] dt

= [(t^2 + 1)(2t^3 + 2t)(∂f/∂x) + (t^3 + t)(9t^4 + 3t^2)(∂f/∂y)] dt

Therefore, c ∇f · dr = [(2t^5 + 2t^3)(∂f/∂x) + (9t^7 + 3t^5)(∂f/∂y)] dt.

The coordinates of a vertex are contingent upon the type of figure it is associated with. Accordingly, there are certain methods to locate the coordinates of vertices distinguishing multiple shapes:

For a parabola in standard form (y = ax^2 + bx + c), its vertex's x-coordinate can be identified by -b/2a, with y-coordinate deducible through substitution into equation.

In the case of a triangle, its vertex is situated at the union of two sides; therefore, if the coordinates of the triad of vertices are accessible, use of the distance formula will ascertain the measurement of each side.
