The diagonal distance across a square of size 6 is approximately 8.49 units.

To find the diagonal distance across a square of size 6, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is the diagonal distance across the square, and the other two sides are the sides of the square, each of length 6.

So, we can set up the equation as follows:

c^2 = a^2 + b^2

where c is the length of the diagonal, and a and b are the lengths of the sides of the square. Substituting in the values we have:

c^2 = 6^2 + 6^2
c^2 = 36 + 36
c^2 = 72

To solve for c, we take the square root of both sides:

c = sqrt(72)
c ≈ 8.49

Windy's widget stock increased in value by approximately 27.44%.

To find the percent increase in the value of the widget stock, we can use the following formula:

percent increase = [(new value - old value) / old value] x 100%

We are given that Windy bought the widget stock at 14.125 and sold it for 18, so the old value (the purchase price) is 14.125 and the new value (the selling price) is 18. Substituting these values into the formula, we get:

percent increase = [(18 - 14.125) / 14.125] x 100%

percent increase = 3.875 / 14.125 x 100%

percent increase = 0.2744 x 100%

percent increase = 27.44%

Therefore, Windy's widget stock increased in value by approximately 27.44%.

The answer to the integral 0∫π/3 cos⁴xsinx dx using a u-substitution is -5/24 - √3/24, or approximately -0.315.To use a u-substitution to evaluate 0∫π/3 cos⁴xsinx dx, we will use the following steps:

Step 1: Choose a u-substitution that simplifies the integral. In this case, we will let u = cosx, which will allow us to rewrite the integral as 0∫1 u⁴(1-u²)du.

Step 2: Substitute the expression for u into the integral, and simplify. Using the substitution u = cosx, we have:

0∫π/3 cos⁴xsinx dx = 0∫1 u⁴(1-u²)du

Step 3: Evaluate the integral using standard integration techniques. Integrating u⁴(1-u²) with respect to u, we get:

∫ u⁴(1-u²)du = (1/5)u⁵ - (1/3)u³ + C

Step 4: Evaluate the integral from 0 to 1 using the substitution u = cosx. Substituting back, we have:

0∫π/3 cos⁴xsinx dx = (1/5)cos⁵x - (1/3)cos³x ∣₀ᴰ³/₃

Evaluating this expression at the limits of integration, we get:

(1/5)(cos⁵(π/3) - cos⁵(0)) - (1/3)(cos³(π/3) - cos³(0))

Simplifying, we get:

(1/5)(27/64 - 1) - (1/3)(3√3/8 - 1)

= -1/120 (27 - 64) - √3/24 + 1/3

= -5/24 - √3/24

Therefore, the answer to the integral 0∫π/3 cos⁴xsinx dx using a u-substitution is -5/24 - √3/24, or approximately -0.315.

Answer:

To find the values of a and b, we need to find the equation of the tangent to the curve at x=2.

We begin by finding the derivative of the function y=ax^2 -5x + 2:

y' = 2ax - 5

Next, we can substitute x=2 into the derivative to find the slope of the tangent at x=2:

y'(2) = 2a(2) - 5 = 4a - 5

We know that the equation of the tangent line at x=2 is y=7x+b. To find b, we can substitute x=2 and solve for y:

y=7x+b

y=7(2)+b

y=14+b

Now that we know that the point (2, 14+b) lies on the curve and the tangent, we can set the derivative of the curve equal to the slope of the tangent at x=2:

4a - 5 = 7

Solving for a, we get:

4a = 12

a = 3

Now we can substitute a=3 into the equation of the derivative to find the slope of the tangent at x=2:

y'(2) = 4a - 5 = 7

Therefore, the equation of the tangent to the curve y=ax^2 -5x + 2 at the point where x=2 is y=7x+0.

So, the values of the constants are a=3 and b=0.

The values of constants 'a' and 'b' are determined based on the properties of the tangent line at a given point. By taking the derivative to find the slope of the tangent and substituting the given X-value, we find that a = 3. By comparing the Y-values in both original and tangent line equations, we find that b = -10.

To find the values of the constants a and b, you should first take the derivative of the equation of the curve to find the slope of the tangent at any point. Here, the equation is y = ax^2 - 5x + 2. The derivative is y' = 2ax - 5. We substitute the given value of x=2 into this equation to find the slope of the tangent at this point, which is stated to be 7. So, 2a*2 - 5 = 7, solving for a we get a = 3.

Next, we need to find the value of b. We know the equation of the tangent line is y = 7x + b and we also know that the tangent line touches the curve at the point where x = 2. Thus, we substitute x = 2 into both equations to find the corresponding y value. That must be equal in both equations since it's the same point. So, we substitute x=2 in the curve's equation to find y, we get y = 3*2^2 - 5*2 + 2 = 4. But, from the tangent's equation y = 7*2 + b, solving for b gives us b = 4 - 14 = -10.

Since the triangle is isosceles, it has two sides of equal length. Therefore, the perimeter of the triangle can be expressed as:

perimeter = 6 + x + x

Simplifying this equation, we get:

perimeter = 2x + 6

We know that the perimeter is 22 cm, so we can set up an equation and solve for x:

22 = 2x + 6

Subtracting 6 from both sides, we get:

David cut out a triangular piece from one side.

We are given:

** The triangle height = 3 inches

** The triangle base = 5 inches

** The triangle extends 11 inches from the edge

To find the area of the triangle:

There are 100 little cubes that have paint on at least one side.

To find the number of little cubes that have paint on at least one side, we need to calculate the surface area of the large cube, which is 6 times the area of one face. Since each face is a 10x10 square, the area of one face is 10x10 = 100 square inches. So, the total surface area of the cube is 6 x 100 = 600 square inches.

Each little cube has a surface area of 1x6 = 6 square inches, since it has 6 faces. Therefore, the number of little cubes with paint on at least one side is the surface area of the big cube divided by the surface area of one little cube.

600 square inches (surface area of big cube) divided by 6 square inches (surface area of one little cube) = 100 little cubes.

Therefore, there are 100 little cubes that have paint on at least one side.

Charlotte needs a total of 3141/8 square inches of construction paper for her project.

To find the total square inches of construction paper needed for Charlotte's project, we need to calculate the area of each rectangle and then sum them together.

Rectangle 1:

Length = 20 inches

Width = 14 1/4 inches

Area of Rectangle 1 = Length × Width

= 20 inches × 14 1/4 inches

To multiply mixed numbers, we first convert the mixed number to an improper fraction:

14 1/4 inches = (14 × 4 + 1) / 4 = 57 / 4 inches

Now we can calculate the area:

Area of Rectangle 1 = 20 inches × 57 / 4 inches

To multiply fractions, we multiply the numerators together and the denominators together:

Area of Rectangle 1 = (20 × 57) / (1 × 4) square inches

= 1140 / 4 square inches

= 285 square inches

Rectangle 2:

Length = 10 1/2 inches

Width = 10 1/4 inches

Area of Rectangle 2 = Length × Width

= (10 × 2 + 1) / 2 inches × (10 × 4 + 1) / 4 inches

= (21 / 2) inches × (41 / 4) inches

To multiply fractions:

Area of Rectangle 2 = (21 × 41) / (2 × 4) square inches

= 861 / 8 square inches

Now we can find the total area by summing the areas of both rectangles:

Total area = Area of Rectangle 1 + Area of Rectangle 2

= 285 square inches + 861 / 8 square inches

To add the fractions, we need a common denominator:

861 / 8 square inches = (861 × 1) / (8 × 1) square inches

= 861 / 8 square inches

Total area = 285 square inches + 861 / 8 square inches

= (285 × 8) / (1 × 8) square inches + 861 / 8 square inches

= (2280 + 861) / 8 square inches

The given statement "Lambda and r are related; specifically the natural log of lambda is equal to r." is False because lambda and r are not necessarily related in such a way.

Lambda and r are both parameters that can be used to model exponential decay or growth, but they have different interpretations and units of measurement.

Lambda, denoted as λ, is the decay constant or the rate at which a quantity decreases over time in an exponential decay model. It has units of inverse time (e.g., per second, per year). The natural logarithm of λ is not equal to r, but rather to the negative of the decay rate: ln(λ) = -k, where k is the decay rate.

On the other hand, r is the growth rate or the rate at which a quantity increases over time in an exponential growth model. It has units of inverse time (e.g., per second, per year) like lambda. The natural logarithm of the base of the exponential growth function is equal to r: ln(b) = r, where b is the base of the exponential function.

The solution of the graph of the system of equations is:

x = 1, y = 2

To solve the system of equations graphed on the coordinate axes, we need to look for the point of intersection of the two lines.

Looking at the graph, you will notice that the two lines meet at a point with the coordinate values of (1, 2) as indicated (check attached image).

Thus, the x and y values of the point of intersection is the solution of the graph of the systems of equation. Thus:

x = 1, y = 2
