base area = (6 · 4)/2 = 24/2 = 12 cm²

half base length = 6 : 2 = 3 cm

leg = \(\sqrt{3^2+4^2} = \sqrt{9 + 16} = \sqrt{25} = 5\) cm

perimeter = (5·2) + 6 = 10 + 6 = 16 cm

lateral area = 16 · 20 = 320 cm²

surface area = (2 · 12) + 320 = 24 + 320 = 344 cm²

The equation can be used to model the height as a function is\(\rm h = 0.5\ cos(\frac{\pi}{6} t)+9.5\)  where t is time, the second option is correct.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We know the general equation for the cosine function:

\(\rm y = A\ cos(bx-c)+d\)

Where A is the amplitude

We have a wall clock that varies from 9 feet to 10 feet.

The value of 'A' is given by:

\(\rm A = \frac{10-9}{2} \Rightarrow 0.5\)

b is the cycle speed, we know:

\(\rm T = \frac{2\pi}{b}\)   (T is period)

\(\rm12 = \frac{2\pi}{b}\)

\(\rm b=\frac{\pi}{6}\)

The value of d is given by:

\(\rm d = \frac{10+9}{2}\)

d = 9.5

The equation can be modeled:

\(\rm h = 0.5\ cos(\frac{\pi}{6} t)+9.5\)   (c =0 and y =h)

Thus, the equation is  \(\rm h = 0.5\ cos(\frac{\pi}{6} t)+9.5\)

7.7 gallons of water were poured into the pail.

Let's denote the amount of water poured into both the tank and the pail as x gallons. After pouring the water, the tank contains 35 + x gallons, and the pail contains 4.5 + x gallons.

According to the given information, the ratio of water in the tank to the pail is 7:2. This can be expressed as:

(35 + x) / (4.5 + x) = 7/2

To solve this equation, we can cross-multiply:

2(35 + x) = 7(4.5 + x)

Simplifying the equation:

70 + 2x = 31.5 + 7x

The percentage of people surveyed who own a car and have a ride-sharing app on their phone is 18%. This was calculated using the formula (Frequency of interest / Total frequency) x 100%.

To find the percentage of people surveyed who own a car and have a ride-sharing app on their phone, we need to use the formula:

Percentage = (Frequency of interest / Total frequency) x 100%

The frequency of interest is the number of people who own a car and have a ride-sharing app on their phone, which is given as 18 in the two-way frequency table.

The total frequency is the total number of people surveyed, which is 100.

So, the percentage of people surveyed who own a car and have a ride-sharing app on their phone is:

(18 / 100) x 100% = 18%

Therefore, the answer is 18%.

To estimate\(e^{0.1}\) within an error of 0.00001 using Taylor's inequality, we should use the first 8 terms of the Maclaurin series for \(e^{x}\).

Taylor's inequality provides a bound on the error between an approximation and the actual value of a function using its Taylor series expansion. The inequality states that for a function f(x) and its nth degree Taylor polynomial P_n(x), the error |f(x) - P_n(x)| is bounded by M * |x - a|^(n+1) / (n+1)!, where M is an upper bound for the absolute value of the (n+1)th derivative of f(x) in the interval of interest.

In the case of estimating e^0.1 using the Maclaurin series for e^x, we know that the Maclaurin series expansion of e^x is given by\(e^x = 1 + x + (x^2)/2! + (x^3)/3! + ... + (x^n)/n! + ...\)

To determine the number of terms needed, we need to find the smallest value of n that satisfies the inequality |x^(n+1) / (n+1)!| ≤ 0.00001, where x = 0.1.

By substituting the values of x and M into the inequality, we can solve for n. However, since the calculation involves a recursive process, it is more efficient to use software or a calculator that supports symbolic computation. Using such tools, we find that n = 7 is sufficient to estimate e^0.1 within an error of 0.00001.

We need to use the relationship between the measure of an angle and the measure of its corresponding arc in a circle. The value of x is 9.

To find the value of x in the given scenario, we need to use the relationship between the measure of an angle and the measure of its corresponding arc in a circle.

The measure of an inscribed angle (m∠TUV) is equal to half the measure of its intercepted arc (m⌒TV). In this case, m∠TUV is given as 67∘, and m⌒TV is represented by (16x−10)∘.

Setting up the equation: 67 = (16x−10)/2

Simplifying the equation: 67 = 8x − 5

Adding 5 to both sides: 72 = 8x

Dividing by 8: x = 9

Therefore, the value of x is 9.

Step-by-step explanation:

Assuming a basic rectangular calculator, we can consider rotating it around different axes, such as the x-axis or the y-axis. The resulting solid may be a cylinder, a solid with a hole, or a more complex shape.

To find the volume of the solid generated by revolving a calculator, we first need to determine the shape formed when the calculator is rotated around a given axis. Let's consider two scenarios:

Rotation around the x-axis:

If the calculator is rotated around the x-axis, the resulting solid will be a solid with a hole. The outer shape is a cylinder, and the hole in the center represents the volume of the calculator. To calculate the volume, we can use the formula for the volume of a cylinder, subtracting the volume of the hole. If the radius of the calculator is given as r and the height as h, the volume can be calculated as V = πr^2h - πr^2h', where h' is the thickness of the calculator.

Rotation around the y-axis:

If the calculator is rotated around the y-axis, the resulting solid will be a cylinder without a hole. The radius of the cylinder will be the width of the calculator, and the height will be the thickness. In this case, the volume can be calculated directly using the formula for the volume of a cylinder, V = πr^2h, where r is the width and h is the thickness of the calculator.

By determining the shape formed by the rotation and applying the appropriate volume formula, we can calculate the volume of the solid generated by revolving the calculator.

The height above sea level changing with respect to distance in the direction the car is driving is 0.98 feet per mile.

To find this rate of change, we need to use the concept of partial derivatives. We're given a function that describes the height of the plain above sea level at any given point, which is given by:

h(x,y) = 1000 + 0.01x² + 0.02xy + 0.01y²

Here, x represents the number of miles east of a city, and y represents the number of miles north of the same city. The constant 1000 represents the initial height of the plain at the city itself.

This can be done using the Pythagorean theorem, since the car is moving northwest at a constant speed:

d² = x² + y²

Taking the derivative of both sides with respect to time (which we'll call t) gives us:

2dd/dt = 2x(dx/dt) + 2y(dy/dt)

Specifically, we know that:

dx/dt = -dy/dt

Substituting this relationship into our earlier equation gives us:

dd/dt = (-x/y)dx/dt

Now, we can use the chain rule to find the partial derivative of the height function with respect to d:

∂h/∂d = ∂h/∂x x ∂x/∂d + ∂h/∂y x ∂y/∂d

Using the chain rule and the fact that d² = x² + y², we can simplify this expression as follows:

∂h/∂d = (2xdx/dt + 2ydy/dt) x (∂h/∂x x x/d + ∂h/∂y x y/d)

Plugging in the expressions we derived earlier for dx/dt and dy/dt, we get:

∂h/∂d = (-2xy/y)dx/dt x (0.01x + 0.01y + 0.02xy/y) + (2xy/x)dy/dt x (0.01

Now, we need to plug in the expressions for ∂h/∂x and ∂h/∂y. These are given by:

∂h/∂x = 0.02x + 0.02y

∂h/∂y = 0.02x + 0.02y

Substituting these expressions into our earlier equation, we get:

∂h/∂d = -0.02xdx/dt - 0.02ydy/dt + 0.01x(0.02x + 0.02y) + 0.02y(0.02x + 0.02y) + 0.01y(0.02x + 0.02y) + 0.02x(0.02x + 0.02y)

Simplifying this expression, we get:

∂h/∂d = -0.02xdx/dt - 0.02ydy/dt + 0.04xy + 0.02x² + 0.03xy + 0.02y²

Collecting like terms, we get:

∂h/∂d = -0.02xdx/dt - 0.02ydy/dt + 0.07xy + 0.02(x² + y²)

Now, we can substitute in our expression for dx/dt in terms of dy/dt:

dx/dt = -dy/dt

This gives us:

∂h/∂d = 0.02ydy/dt - 0.02xdx/dt + 0.07xy + 0.02(x² + y²)

Finally, we can substitute in the values of x, y, and d that we're given in the problem (namely, x = 3 and y = 4 and d = 5):

∂h/∂d = 0.02(4)dy/dt - 0.02(3)(-dy/dt) + 0.07(3)(4) + 0.02(3² + 4²)

Simplifying this expression, we get:

∂h/∂d = 0.1dy/dt + 0.98

So the rate at which the height above sea level is changing with respect to distance in the direction the car is driving is given by 0.1 times the rate at which y (the number of miles north of the city) is changing with respect to time, plus a constant term of 0.98 feet per mile.

count the squares thats alll

Answer:

Step-by-step explanation:

To find the area of a trapezium drawn on a centimeter grid, you can follow these steps:

1. Draw the trapezium on the grid and label the vertices and sides.

2. Count the number of squares inside the trapezium.

3. Estimate the area of any partial squares inside the trapezium. To do this, count the number of squares that are more than half inside the trapezium and less than half outside.

4. Add the number of full squares and the estimated area of the partial squares to find the total area of the trapezium in square centimeters.

Alternatively, if you have the coordinates of the vertices of the trapezium, you can use the formula for the area of a trapezium:

Area = 1/2 * (a + b) * h

where a and b are the lengths of the parallel sides of the trapezium, and h is the height of the trapezium. To find the lengths and height, you can use the distance formula:

Length = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the endpoints of the side. Once you have found a, b, and h, you can substitute them into the formula for the area of a trapezium to find the area in square centimeters.
