Box of candy contains 0. 6 of a pound of caramels 3. 6 pounds of coconut What percent the contents of the box, by weight consists of caramels?

Answer:

x = 45°

Step-by-step explanation:

Since a triangle has a total of 180°, we can make an equation and add all 3 of these angles together:

30° + (2x +10)°+ 50° = 180°

30° + 10° + 50° + 2x = 180°

90° + 2x = 180°

2x = 180° - 90°

2x = 90° / : 2

x = 45°

Answer:

610 feet

Step-by-step explanation:

From the question :

1 scarf = 2.5 yards of yarn

84 scarves = x yards

Cross Multiply

1 scarf × x yards = 84 × 2.5 yards

x yards = 210 yards

Hence, 84 scarves require 210 yards

Converting yards to feet

1 yard = 3 feet

210 yards = x feet

x feet × 1 yard = 210 yards × 3 feet

x feet = 210 yards × 3 feet/1 yards

x feet = 610 feet

Hence, if Janet wants to make 84 scarves, she need to buy 610 feet of yarn

Formula to find interest :

I = Prt

Solving :

Future value :

a) U is subspace of R^3.

b) The set {(3, -2, 0), (0, 1/2, 1)} is a basis for U.

c) 2.

a) To show that U is a subspace of R^3, we need to verify the following three conditions:

i) The zero vector (0, 0, 0) is in U.

ii) U is closed under addition.

iii) U is closed under scalar multiplication.

i) The zero vector is in U since 0 + 2(0) - 3(0) = 0.

ii) Let (x1, y1, z1) and (x2, y2, z2) be two vectors in U. Then we have:

x1 + 2y1 - 3z1 = 0 (by definition of U)

x2 + 2y2 - 3z2 = 0 (by definition of U)

Adding these two equations, we get:

(x1 + x2) + 2(y1 + y2) - 3(z1 + z2) = 0

which shows that the sum (x1 + x2, y1 + y2, z1 + z2) is also in U. Therefore, U is closed under addition.

iii) Let (x, y, z) be a vector in U, and let c be a scalar. Then we have:

x + 2y - 3z = 0 (by definition of U)

Multiplying both sides of this equation by c, we get:

cx + 2cy - 3cz = 0

which shows that the vector (cx, cy, cz) is also in U. Therefore, U is closed under scalar multiplication.

Since U satisfies all three conditions, it is a subspace of R^3.

b) To find a basis for U, we can start by setting z = t (where t is an arbitrary parameter), and then solving for x and y in terms of t. From the equation x + 2y - 3z = 0, we have:

x = 3z - 2y

y = (x - 3z)/2

Substituting z = t into these equations, we get:

x = 3t - 2y

y = (x - 3t)/2

Now, we can express any vector in U as a linear combination of two vectors of the form (3, -2, 0) and (0, 1/2, 1), since:

(x, y, z) = x(3, -2, 0) + y(0, 1/2, 1) = (3x, -2x + (1/2)y, y + z)

Therefore, the set {(3, -2, 0), (0, 1/2, 1)} is a basis for U.

c) Since the basis for U has two elements, the dimension of U is 2.

The width of a rectangular piece is 28 and the length is 58.

let us consider

w=width

w+30=length

After cutting:

w-12 =width

w + 30-12=length, or w + 18

Now to calculate the length and width consider the area of a rectangle:

Area of a rectangle=w*l

substitute the values in the above formula:

(w-12)(w+18)(6) = 2400

(w-12 )(w+18) = 400

w²+6w-216 = 400

w²+6w-616 = 0

(w + 28)(w - 22) = 0

The roots of the equation are {-22, 28}.

to find the length just substitute in the length formula:

length=28+30

length=58.

The width is 28 and the length is 58.

A line's slope determines how steep it is. A mathematical equation for the gradient is called "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical change (rise) between two points to the horizontal change (run) between those same two spots. When a straight line's equation is written as y = mx + b, the slope-intercept form of an equation is employed to express it. The y-intercept is located at a location where the line's slope is m, b is b, and (0, b). For instance, the slope of the equation y = 3x - 7 and the y-intercept (0, 7).The line's slope is m. b is b at the point where the y-intercept is, and (0, b). As an illustration, the equation y = 3x - 7 has a slope of 3, and its y-intercept is (0, 7).

city - north at (0,65)

city-east at (59,0)

Slope is m=(-65/59)

\(B= y - mx = 65 - (-65/59)(0) = 65\)

The equation of the line between the cities is y = (-65/59)x + 65

The critical point of f at z = 1 is a local minimum.

To find the critical points of the function f(z, 3) = 4z^2 - 8z + 1, we need to find the values of z where the first partial derivatives with respect to z are equal to zero. Let's solve it step by step.

Take the partial derivative of f with respect to z:

∂f/∂z = 8z - 8

Set the derivative equal to zero and solve for z:

8z - 8 = 0

8z = 8

z = 1

The critical point of f occurs when z = 1.

To determine whether the critical point is a local minimum, local maximum, or a saddle point, we can use the second partial derivative test. We need to calculate the second partial derivative ∂²f/∂z² and evaluate it at the critical point (z = 1).

Taking the second partial derivative of f with respect to z:

∂²f/∂z² = 8

Evaluate the second derivative at the critical point:

∂²f/∂z² at z = 1 is 8.

Analyzing the second derivative:

Since the second derivative ∂²f/∂z² = 8 is positive, the critical point (z = 1) corresponds to a local minimum.

Therefore, the critical point of f at z = 1 is a local minimum.

the limits of integration become u = 576(-1.079 + 3)²/4² to u = 576(3 + 3)²/0²:

L =

(2/3)∫(u = 207.36 to u = ∞) sqrt[1 + u] (-y³ / 1152(x + 3)²) du

We can use the formula for arc length of a curve given by:

L = ∫(a to b) sqrt[1 + (dy/dx)²] dx

First, we need to solve for x in terms of y:

y² = 16(x + 3)³

(x + 3)³ = y²/16

x + 3 = (y/2)^(2/3)

x = (y/2)^(2/3) - 3

Next, we find the derivative dy/dx:

y² = 16(x + 3)³

2y dy/dx = 16(3(x + 3)²)

dy/dx = 24(x + 3) / y

Now, we substitute x = (y/2)^(2/3) - 3 and dy/dx = 24(x + 3) / y into the formula for arc length:

L = ∫(0 to 1) sqrt[1 + (dy/dx)²] dx

L = ∫(0 to 1) sqrt[1 + (24(x + 3) / y)²] dx

L = ∫(0 to 4) sqrt[1 + (24(x + 3) / y)²] (2/3)y^(1/3) dy

L = (2/3)∫(0 to 4) sqrt[1 + 576(x + 3)²/y²] y^(1/3) dy

Now, we make the substitution u = 576(x + 3)²/y²:

du/dy = -1152(x + 3)²/y³

dy/du = -y³ / 1152(x + 3)²

When y = 4, x = (4/2)^(2/3) - 3 = -1.079

When y = 0, x = (0/2)^(2/3) - 3 = -3

The recursive formula for the sequence is T(n+1) = Tn - 3 where T1 = 19 and the explicit formula for the sequence is Tn = 22 - 3n

On the given graph, we have the following points

19, 16, 13, 10, 7

These points represent the nth term of the sequence

See that the points have a common difference of -3

Hence, the sequence is an arithmetic sequence

In (a), we have

T1 = 19

d = -3

So, we have

T2 = T1 + d

This gives

T2 = T1 - 3

Express 2 as 1 + 1

So, we have

T(1+1) = T1 - 3

Express 1 as n

So, we have

T(n+1) = Tn - 3

Hence, the recursive formula for the sequence is T(n+1) = Tn - 3 where T1 = 19

In (a), we have

T1 = 19

d = -3

So, we have

Tn = T1 + (n - 1)d

This gives

Tn = 19 + (n - 1) * -3

Evaluate

Tn = 19 + 3 - 3n

Evaluate the sum

Tn = 22 - 3n

Hence, the explicit formula for the sequence is Tn = 22 - 3n

Inverse distance weighting (IDW) spatial interpolation is a technique for estimating values at unknown places from nearby known values. The equation for IDW is: Z(x) = Σ [wi * Zi] / Σ wi. The power parameter (p) and the search radius (r) are among the IDW's parameters.

Spatial interpolation by inverse distance weighting (IDW) is a method used to estimate values at unknown locations based on nearby known values. It is commonly used in geostatistics and spatial analysis to fill in missing or unobserved data points in a continuous surface.

The equation for IDW is as follows:
Z(x) = Σ [wi * Zi] / Σ wi
In this equation,

Z(x) represents the estimated value at location x,

Zi represents the known value at location i, and

wi represents the weight assigned to each known value based on its distance from location x.

The parameters of IDW include the power parameter (p) and the search radius (r).

The power parameter determines the influence of each known value on the estimated value at the unknown location. A higher power value gives more weight to the closest points, while a lower power value spreads the influence of nearby points more evenly.

The search radius defines the distance within which neighboring points are considered for interpolation.

IDW has several properties that are important to consider:
1. Inverse relationship: IDW assumes an inverse relationship between distance and influence. Closer points have a greater influence on the estimated value than farther points.
2. Deterministic: IDW provides a deterministic estimate at each unknown location based on the known values within the search radius.
3. Smoothing effect: IDW tends to smooth out abrupt changes in the data. This can be an advantage when dealing with noisy or inconsistent data, but it can also result in the loss of detailed information.
4. Sensitivity to parameter selection: The choice of power parameter and search radius can significantly impact the results of IDW. It is important to select appropriate values based on the characteristics of the data and the desired outcome.

The balloon was flying at a height of 176.58 m .

The fundamentals of an object's motion, such as its position, velocity, or acceleration over time, are defined by kinematics equations of motion. An object's motion in one, two, and three dimensions is determined by these three equations of motion. One of three equations of motion can be used to calculate components like displacement (s), velocity (initial and final), time (t), and acceleration (a). The following are the three motion equations:

Initial formula: v = u + at

The second formula is s = ut + 0.5at2.

The third formula is v2 = u2 + 2as.

Let t stand for the duration of the metal bat's flight, s for the height at which the hot air balloon was traveling, and u for the metal bat's initial vertical velocity since it is simply dropped.

Given: The metal bat took 6 seconds to reach the ground.

With t = 12 and u = 0, the second equation of motion gives us s = 0*t + 0.5*9.81*162 = 176.58 m.
