Answer: He will need 49 tiles.

Step-by-step explanation:

Given: The patio will measure 13.5 feet by 43 feet.

Area of patio = 13.5 feet x 43 feet [Area = length x width]

= 580.5 sq. feet

Since area of each concrete tile = 12 sq. inch

Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)

= 580.5 ÷ 12

= 48.375 sq. inch ≈49

it is true that  0.5% of 200 is 10.

True.

To find 0.5% of a number, we need to multiply the number by 0.5/100, which can be simplified to 5/100 or 1/20. This is because "percent" means "per hundred", so 0.5% is equivalent to 0.5 per 100 or 0.5/100.

Multiplying the number by 5/100 is the same as multiplying it by 0.5/100, so it will give us the correct result.

For example, if we want to find 0.5% of 200, we can multiply 200 by 5/100 or 0.5/100:

\(0.5% of 200 = 200 \times 5/100 = 10\)

Therefore, it is true that  0.5% of 200 is 10.

The equation which is used to find the number of chocolates candy in the jar is given by 18 + 24 + 19 + n = 82 , the number of chocolate candy in the jar is equal to 21.

Number of strawberry candy in the jar = 18

Number of cherry candy in the jar = 24

Number of lime flavored candies = 19

Let 'n' be the number of chocolate candy in the jar

Total number of candy in the jar = 82

Equation used to represent the given condition is :

18 + 24 + 19 + n = 82

⇒ 61 + n = 82

⇒ n = 82 - 61

Answer:

The slope is 0.98 and the y-intercept is 1.44.

Step-by-step explanation:

The equation is a linear equation in the Slope-Intercept form y=mx+b. It’s called this because it identifies the slope m and the point on the y-axis at which the line intersects.

Step-by-step explanation:

y = x² - 3x + 6

y = 2x + 6

y = y

x² - 3x + 6 = 2x + 6

x² - 5x = 0

x(x - 5) = 0

x = 0 and x = 5

y = 2x + 6 and y = 2x + 6

y = 2(0) + 6 and y = 2(5) + 6

y = 0 + 6 and y = 10 + 6

y = 6 and y = 16

Answer:

Step-by-step explanation:

I graphed the functions on the graph below so you can see that the horizontal translation is represented by 4.

The total area of the region bounded by the graph of y = x times the square root of \((1 - x^2)\) and the x-axis is 1/2.

Let the region bounded by the graph of y = x times the square root of\((1 - x^2)\) and the x-axis be the region R.

The total area of region R is given by A as;\(A = 2∫_0^1▒〖ydx〗\)

The boundary of the given region is given by y = x times the square root of\((1 - x^2)\) and the x-axis.

Thus, for any x in the interval [0, 1], the boundary of the region R can be represented as;\(∫_0^1▒〖x√(1-x^2)dx〗\)

Let \(u = 1 - x^2,\)

therefore, du/dx = -2x.

It implies that\(dx = -du/2x.\)

The integral becomes;\(∫_1^0▒〖(-du/2)√udu〗=-1/2 ∫_1^0▒√udu\)

=-1/2 2/3

= -1/3

Therefore the total area of the region bounded by the graph of y = x times the square root of \((1 - x^2)\)and the x-axis is 1/2. Hence, option B) 1/2 is the correct answer.

To find the length of the diagonal of square C, 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. Since square C has equal sides, we only need to find the length of one side and then multiply it by the square root of 2 to get the length of the diagonal.

Using the coordinates given, we can find the length of one side by subtracting the x-coordinate of one vertex from the x-coordinate of the other vertex (11 - 1 = 10). We then multiply this by the conversion factor given in the problem (1 square unit = 25 feet) to get the length in feet (10 * 25 = 250). Finally, we multiply this by the square root of 2 to get the length of the diagonal (250 * sqrt(2) ≈ 353.55 feet).

Therefore, if square C has an area of 2500 square units and each unit is equal to 25 feet, then a square with a diagonal length of approximately 353.55 feet would be an accurate representation of square C.

As per the question, the complexity that ranks between the other two is O(n^2) - Quadratic (or Polynomial).

As we compare the run-time complexities, it's crucial to examine the function’s growth with an increase in input size (n).

Let us analyze the growth rates:

Exponential (O(2^n)): The function doubles for each increment in n. This is very fast growth.

Quadratic (O(n^2)): The function grows proportional to the square of n. This is slower growth compared to exponential but faster than logarithmic.

Logarithmic (O(log n)): The function grows very slowly as n increases. The growth rate is less than linear (O(n)).

So the ranking, from slowest to fastest growth, is:

O(log n) - Logarithmic

O(n^2) - Quadratic (or Polynomial)

O(2^n) - Exponential

The correct set of possible results would be (0, 1, 0, 0), (1, 2, 1, 0) and (1, 2, 0, 1).

Your approach seems to be correct, but there seems to be a minor mistake in your final list of possible solutions. Let's go through the steps to clarify.

Given the initial conditions z=t=0, you obtained a partial solution (0,1,0,0).

Next, you solved the homogeneous equations for z=1 and t=0, which resulted in a solution (1,1,1,0).

Similarly, solving the homogeneous equations for z=0 and t=1 gives another solution (1,1,0,1).

To find the general solution, you combine the partial solution with the solutions obtained in the previous step, using parameters a and b.

(0,1,0,0) + a(1,1,1,0) + b(1,1,0,1)

Expanding this expression, you get:

(0+a+b, 1+a+b, 0+a, 0+b)

Simplifying, you obtain the following set of solutions:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Therefore, the correct set of possible results would be:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Note that (0, 1, 1, 1) is not a valid solution in this case, as it does not satisfy the initial condition z = 0.

The strain that exists under a maximum-stress condition is 9.27 × 10^-3.

Given data: Minimum cross-sectional area of femur= 4.4×10^-4 m^2

Compressional force to fracture= 6.100×10^4 N

We need to find the maximum stress that this bone can withstand.

Maximum stress = compressive force / minimum cross-sectional area

                            = 6.1×10^4 / 4.4×10^-4=1.39×10^8 N/m^2

Now, we need to find the strain that exists under a maximum-stress condition.

Since stress = Young’s modulus × strain,

Strain = stress / Young's modulus

Maximum stress = 1.39×10^8 N/m^2

Young's modulus for bone = 1.5 × 10^10 N/m^2

Strain = 1.39×10^8 / 1.5 × 10^10= 0.00927= 9.27 × 10^-3

Therefore, the strain that exists under a maximum-stress condition is 9.27 × 10^-3.
