Answer:

Step-by-step explanation:

The sine model is y=10 sin(1/30 t) + 30.  The 30 represents default distance from the ground, and the ten is required to represent the length of the blades.  Every 30 seconds, one rotation completes, so t must be multiplied by 1/30.

This equation tells us that the cost of x pounds of bananas is equal to the number of pounds of bananas, x, multiplied by the cost per pound

So equation becomes C = 0.70x

We can use proportional reasoning to set up an equation to represent the cost, C, of x pounds of bananas.

We know that 20 pounds of bananas cost 14, so the cost per pound can be found by dividing the total cost by the total weight:

Cost per pound = Total cost / Total weight

Cost per pound = 14 / 20 pounds

Cost per pound = 0.70 per pound

Now, we can use this cost per pound to set up an equation:

C = cost of x pounds of bananas

x = number of pounds of bananas

Cost per pound = 0.70

So, we can write the equation as:

C = 0.70x

This equation tells us that the cost of x pounds of bananas is equal to the number of pounds of bananas, x, multiplied by the cost per pound, 0.70.

Susan bought 1/3 of a yard of material to use for the border for the blanket. She cut the material into 4 same-size strips. The problem is asking for the part of a whole yard that each strip represents.

Since Susan has 1/3 of a yard of material and she cut it into 4 same-size strips, we can use division to find the fraction of the material that each strip represents.

Therefore, the fraction of the material that each strip represents is 1/3 ÷ 4.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of 4 is 1/4, so we can rewrite the expression as:

1/3 ÷ 4 = 1/3 × 1/4

Given the above parallelogram,

1) ∠ABC = 90°

2) ∠BCD = 90°
3) ∠CDA = 90°
4)  ∠DAB = 90°

To find the value of the angles, we need to first find x. Given that ∠ABC  = (x+35)° on the basis of opposite angles in a parallelogram, and

∠CDA = (180-(3x-75)°

since ∠ABC and ∠CDA  are opposite angles.

We can state that
(180-(3x-75)° = (x+35)°  since opposite sides of a parallelogram are equal.
Simplifying the above, we can find x:

180 - (3x - 75) = 180 - 3x + 75 = 255 - 3x

Now we can substitute this expression into the original equation:

255 - 3x = x + 35

To solve for x, we want to isolate the variable on one side of the equation. Let's start by adding 3x to both sides:

255 = 4x + 35

Next, we can subtract 35 from both sides:

220 = 4x

Finally, we can divide both sides by 4 to get the value of x:

x = 55

Therefore, the solution to the equation is x = 55°.

Since x = 55°

∠ABC  = (x+35)°

∠ABC = 55 + 35

∠ABC = 90°


Also, since:
∠CDA = (180-(3x-75)°)
∠CDA = 180- (165-75)

∠CDA = 90°

Since ∠DAB = (3x-75)° on the basis of alternate angles,
∠DAB = (3(55) -75)°

∠DAB  = 165 -75

∠DAB  = 90°


Since  ∠DAB is opposite ∠BCD and Opposite angles of a parallelogram are equal, thus, ∠BCD is also 90°

The differential equation with initial conditions describing the motion is F = -k * (s(t) + 5) - 6g and the displacement of the mass from its equilibrium position as a function of time s(t) = (3 * r2 * e^(r1*t)) / (r2 - r1) + (3 * r1 * e^(r2*t)) / (r1 - r2)

The differential equation for the motion of the mass is given by Newton's Second Law, F = ma:

F = -k * (s(t) + 5) - 6g

where k is the spring constant, s(t) is the displacement from the equilibrium position, and g is the acceleration due to gravity. The initial conditions are s(0) = 3 and s'(0) = 0, since the spring is initially stretched an additional 3 cm and released from rest.

We can rearrange the equation to get:

s''(t) + (k/6) * s(t) = -5k/6 - g

This is a second-order linear homogeneous differential equation with constant coefficients. The general solution is:

s(t) = C1 * e^(r1*t) + C2 * e^(r2*t)

where r1 and r2 are the roots of the characteristic equation:

r^2 + (k/6) * r = -5k/6 - g

Using the quadratic formula, we get:

r1,2 = -(k/12) ± √((k/12)^2 + 5k/6 + g)

We can find the values of C1 and C2 by applying the initial conditions:

s(0) = C1 + C2 = 3

s'(0) = C1 * r1 + C2 * r2 = 0

Solving for C1 and C2, we get:

C1 = (3 * r2) / (r2 - r1)

C2 = (3 * r1) / (r1 - r2)

Substituting back into the general solution, we get:

s(t) = (3 * r2 * e^(r1*t)) / (r2 - r1) + (3 * r1 * e^(r2*t)) / (r1 - r2)

This is the displacement of the mass from its equilibrium position as a function of time.

Jacob needs 290.92 ft² of carpet in total to cover both the living room and the dining room.

To find out how much carpet Jacob needs to cover his living room, we can multiply the length and width of the room:

15 ft x 12 1/3 ft = 15 ft x (37/3) ft = 555/3 ft²

To simplify this fraction, we can divide both the numerator and denominator by 3:

555/3 ft² = 185 ft²

So the living room requires 185 square feet of carpet.

To find out how much carpet Jacob needs to cover his dining room, we can multiply the length and width of that room:

10 1/4 ft x 10 1/3 ft = (41/4) ft x (31/3) ft = 1271/12 ft²

To simplify this fraction, we can divide both the numerator and denominator by 1:

1271/12 ft² = 105.92 ft² (rounded to two decimal places)

So the dining room requires 105.92 square feet of carpet.

To find out how much carpet Jacob needs in total, we can add the amount of carpet required for each room:

185 ft² + 105.92 ft² = 290.92 ft²

The car's value will decrease at rate of 1/5.

Rate refers to the ratio between two quantities with different units. For example, if you travel 100 miles in 2 hours, your rate of speed would be 50 miles per hour (mph).

From the graph, we have the following:

1: At mileage (x) = 20,000 miles, value of car (y) = $12000

2: At mileage (x) = 40,000 miles, value of car (y) = $8000

Rate = (y2 - y1)/(x2 - x1)

Rate = (8000 - 12000)/(40000 - 20000)

We have a consistent independent equation when a system of linear equations has exactly one solution. When this occurs, the graphs of the system's lines cross at exactly one point.

For our question, we can start by rearranging the first equation to isolate y:

[tex]4x + y = 4\\y = -4x + 4[/tex]

We can see that the second equation is already in the form y = mx + b, where m is the slope and b is the y-intercept. So we can identify that the slope of the second equation is -4 and the y-intercept is 4.

Now we can compare the slopes and y-intercepts of the two equations to determine the classification of the system of equations:

In this case, we can see that the slopes of the two equations are different (-4 and 0) and the y-intercepts are the same (4). Therefore, the system is consistent and there is a unique solution. So the classification of the system of linear equations 4x + y = 4 and y = -4x + 4 is: consistent and independent

Step-by-step explanation:

You want the measure of the acute angle where a tangent meets a chord that intercepts an arc of 300°.

An angle inscribed in a circle has half the measure of the arc it intercepts.

If one leg of that inscribed angle degenerates in length to zero, then the "inscribed" angle becomes the angle between the remaining chord and the tangent to one end of that chord.

In other words, the measure of the angle marked x° is half the measure of the arc it intercepts.

  x° = 1/2(360° -300°) = 1/2(60°)

  x° = 30°
