To be classified as rain, water droplets that fall from a cloud must have a minimum diameter of 0.5 millimeters.

To be classified as rain, water droplets that fall from a cloud must have a minimum diameter of 0.5 millimeters (0.02 inches).

In geometry, the diameter of a circle is the part of a straight line that goes through the center and ends in the circle. It can also be defined as the longest chord of a circle. These two concepts also apply to the diameter of a sphere.

In modern usage, the length d of a diameter is also called a diameter. In this sense, we speak of diameter rather than diameter (referring to the line segment itself), because all diameters of a circle or sphere have the same length, which is twice the radius r.

Since we can't have a fraction of a year, we need to round up to the equation nearest whole number. Therefore, it will take at least 7 years for the value of the car to be less than $3,000.

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x Plus 3" equals the number "9." The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. The variable x is raised to the second power in the equation "x2 + 2x - 3 = 0." Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.

V(1) = 0.85 * 12,900 = $10,965

V(2) = 0.85 * 10,965 = $9,320.25

\(V(n) = 0.85^n * 12,900\\0.85^n * 12,900 < 3,000\\n > log(3,000/12,900) / log(0.85)\\n > 6.48\\\)

Since we can't have a fraction of a year, we need to round up to the nearest whole number. Therefore, it will take at least 7 years for the value of the car to be less than $3,000.

Answer:

9 years

Step-by-step explanation:

As the car depreciates at a constant rate of 15% each year, we can use the exponential decay formula to find the value of the car after t years.

\(\boxed{f(t)=a(1-r)^t}\)

where:

Given the purchase price of the car is $12,900, a = 12900.

Given the car will depreciate at a rate of 15%, r = 0.15.

Substitute the values of a and r into the formula to create a function for the value of car after t years is:

\(f(t)=12900(1-0.15)^t\)

\(f(t)=12900(0.85)^t\)

To calculate after how many years the value of the car will be less than $3,000, substitute f(t) < 3000 and solve for t.

\(\implies 12900(0.85)^t < 3000\)

Divide both sides by 12900:

\(\implies (0.85)^t < \dfrac{3000}{12900}\)

\(\implies (0.85)^t < \dfrac{10}{43}\)

Take natural logarithms of both sides:

\(\implies \ln (0.85)^t < \ln\left(\dfrac{10}{43}\right)\)

Apply the log power law:

\(\implies t \ln (0.85) < \ln\left(\dfrac{10}{43}\right)\)

Divide both sides by ln(0.85), remembering to change the direction of the inequality sign since ln(0.85) is negative:

\(\implies t > \dfrac{\ln\left(\dfrac{10}{43}\right)}{\ln (0.85)}\)

\(\implies t > 8.9750695...\)

We need to round up to 9 years, since we can't have a fraction of a year.

Therefore, the value of the car will be less than $3,000 after 9 years.

Answer:

The point C is 12.68 km away from the point A on a bearing of S23.23°W.

Step-by-step explanation:

Given that AB is 50 km and BC is 40 km as shown in the figure.

From the figure, the length of x-component of AC = |AB sin 80° - BC cos 20°|

=|50 sin 80° - 40 cos 20°|=11.65 km

The length of y-component of AC = |AB cos 80° - BC sin 20°|

=|50 cos 80° - 40 sin 20°|= 5 km

tan\(\theta\)= 5/11.65

\(\theta\)=23.23°

AC= \(\sqrt{5^2+11.65^2}=12.68\) km

Hence, the point C is 12.68 km away from the point A on a bearing of S23.23°W.

false. The vertical axis is the y-axis, which is where x=0. In this equation, when x=0, we have: y=4(0)-5
y=-5

Therefore, the line produced by the equation Y=4X−5 crosses the vertical axis at y=-5, not y=5.

To further understand this concept, we can visualize the equation on a graph. When we plot the points (0,-5) and (1,-1) (which is found by substituting x=1 into the equation), we can draw a line that passes through both points. This line is the graph of the equation Y=4X−5. We can see that the line crosses the vertical axis (y-axis) at y=-5, which confirms that the answer is false.

In summary, the equation Y=4X−5 crosses the vertical axis (y-axis) at y=-5, not y=5.

Lines 2 and 3 are perpendicular, while Lines 1 and 2, and Lines 1 and 3 are neither parallel nor perpendicular.

To determine whether two lines are parallel, perpendicular, or neither, we need to examine their slopes.

The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. If two lines have the same slope, they are parallel. If the product of their slopes is -1, they are perpendicular. Otherwise, they are neither parallel nor perpendicular.

Line 1: 10x - 4y = -4 can be rewritten in slope-intercept form as y = 2.5x + 1. This means its slope is 2.5.

Line 2: y = 5x + 7 is already in slope-intercept form. Its slope is 5.

Line 3: 5y = 2x + 4 can be rewritten in slope-intercept form as y = 0.4x + 0.8. This means its slope is 0.4.

Now we can compare the slopes of each pair of lines:

Lines 1 and 2: The slope of Line 1 is 2.5 and the slope of Line 2 is 5. These slopes are not equal and their product is not -1, so these lines are neither parallel nor perpendicular.

Lines 1 and 3: The slope of Line 1 is 2.5 and the slope of Line 3 is 0.4. These slopes are not equal and their product is not -1, so these lines are neither parallel nor perpendicular.

Lines 2 and 3: The slope of Line 2 is 5 and the slope of Line 3 is 0.4. Their product is -1, so these lines are perpendicular.

Therefore, Lines 2 and 3 are perpendicular, while Lines 1 and 2, and Lines 1 and 3 are neither parallel nor perpendicular.

Step-by-step explanation:

The system of equations are:

A = 80x + 70    

A = 980 - 50x  

Weeks: x = 7 weeks

Amount of money: $630

Let x represent the number of weeks it will take for both girls to have the same amount of money.

Let A represent the amount both will have equally after x number of weeks.

Thus:

For Kendra, the equation is:

A = 80x + 70    -----(1)

For Mallory, the equation is:

A = 980 - 50x   ------(2)

Thus, for both to have the same amount of money:

80x + 70 = 980 - 50x

80x + 50x = 980 - 70

130x = 910

x = 910/130

x = 7 weeks

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Here RS is the hypotenuse and the legs have measure 5 and 3, thus

RS² = 5² + 3² = 25 + 9 = 34 ( take the square root of both sides )

To compute the directional Gervative of the function f(x,y) = exy - x - 2y at the point P = (2,-1) in the direction of the vector v = , we first need to find the gradient of f at P.

The gradient of f is given by ∇f(x,y) = . So, at the point P = (2,-1), we have ∇f(2,-1) = .

Next, we need to find the unit vector in the direction of v. To do this, we first need to find the magnitude of v, which is ||v|| = √(e^2 + (-2)^2) = √(e^2 + 4).

Then, we can find the unit vector in the direction of v by dividing v by its magnitude:

u = v/||v|| = .

Finally, we can compute the directional Gervative of f at P in the direction of v as follows:

D_v f(2,-1) = ∇f(2,-1) · u = ( · )

= (e^-1 - 1)(e/√(e^2 + 4)) + (e^2 - 2)(-2/√(e^2 + 4))

= -2e/(√(e^2 + 4)) - 4/(√(e^2 + 4))

= (-2e - 4)/(√(e^2 + 4)).

Therefore, the directional Gervative of f at P in the direction of v is (-2e - 4)/(√(e^2 + 4)).
