Answer:

a.  (t - (-2.9))² + 1

Step-by-step explanation:

We are told that Ahmed is modelling the area covered by a moss using the equation A = t² + 5.8t + 9.41.

The given equation is a quadratic equation with a positive leading coefficient. Therefore, the graph is a parabola that opens upwards. This means that the vertex is its lowest point.

The vertex form of a quadratic equation is:

\(\boxed{y = (x - h)^2 + k}\)

where (h, k) is the vertex.

As the vertex is the lowest point, this means that the y-value of the vertex is when the area of moss is at its lowest. We are told that the smallest area of the moss is 1 square centimeter, so k = 1.

The x-value of the vertex can be found by using the formula:

\(h=-\dfrac{b}{2a}\)

for a quadratic in the form ax² + bx + c.

For the given quadratic, a = 1, b = 5.8 and c = 9.41.

Substitute the values of a and b into the formula to find the x-value of the vertex:

\(\implies h=-\dfrac{5.8}{2(1)}=-2.9\)

Finally, substitute h = -2.9 and k = 1 into the vertex form:

\(A=(t-(-2.9))^2+1\)

Therefore, the equivalent expression that contains the number of days before noon on July 1, 2014, as a constant or coefficient, when the moss started with its smallest area of 1 square centimeter is:

This is an arithmetic sequence and the common difference = - 2

You might be a little puzzled by the minus sign in front of the two. You can look at the sequence for the answer. It is going down. A plus 2 would make it go up. Minus signs are always a bit tricky and you have to watch out what you do with them. But the rule is simple

You know that this is an arithmetic sequence because the common difference can be found by adding or subtracting a number from the previous term to get to the next term.

A geometrice sequence would use multiplication or division to get from one term to the next.

Answer:

(-3a+4b) (2x+2y)

Step-by-step explanation:

Expand.

4(x+y)(3a-b)+6(x+y)(2b-3a) = 4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay)

4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay)  = 12ax+12ay-4bx-4by+12bx+12by-18ax-18ay

Calculate like terms.

12ax+12ay-4bx-4by+12bx+12by-18ax-18ay = -6ax-6ay+8bx+8by

Factorise.

-6ax-6ay+8bx+8by = -3a(2x+2y) + 4b(2x+2y)

Factorise further.

-3a(2x+2y)+4b(2x+2y) = (-3a+4b) (2x+2y)

Period of the functions: The period of the function f(t) = (7 cos t)² is given by 2π/b where b is the period of cos t.The period of the function f(t) = cos (2φt²/m) is given by T = √(4πm/φ). The period of the function f(t) = (7 cos t)² is given by 2π/b where b is the period of cos t.

We know that cos (t) is periodic and has a period of 2π.∴ b = 2π∴ The period of the function f(t) =

(7 cos t)² = 2π/b = 2π/2π = 1.

The period of the function f(t) = cos (2φt²/m) is given by T = √(4πm/φ) Hence, the period of the function f(t) =

cos (2φt²/m) is √(4πm/φ).

The function f(t) = (7 cos t)² is a trigonometric function and it is periodic. The period of the function is given by 2π/b where b is the period of cos t. As cos (t) is periodic and has a period of 2π, the period of the function f(t) = (7 cos t)² is 2π/2π = 1. Hence, the period of the function f(t) = (7 cos t)² is 1.The function f(t) = cos (2φt²/m) is also a trigonometric function and is periodic. The period of this function is given by T = √(4πm/φ). Therefore, the period of the function f(t) = cos (2φt²/m) is √(4πm/φ).

The period of the function f(t) = (7 cos t)² is 1, and the period of the function f(t) = cos (2φt²/m) is √(4πm/φ).

The actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.

The margin of error in the report stating that a 10-year-old American child spends an average of 20.02 to 25.36 minutes playing outdoors per day can be calculated by subtracting the lower value from the higher value and dividing by 2. In this case, the margin of error is :

To find the margin of error, we need to calculate the halfway point between these two values.
(25.36 - 20.02) / 2 = 2.67

Therefore, the margin of error is approximately 2.67 minutes. This means that the actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.

Thus, the actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.

D. F(x) = (x - 1)^4

Step-by-step explanation:

To shift a graph h units horizontally, replace x by x - h.

The shift is 1 unit to the right, so the shift is positive 1.

h = 1

x - h = x - 1

Replace x with x - 1.

The coordinates of m with respect to the basis b are  x = [x1 x2 x3]T = [−7/3 −1/3 −1/2]T

To find the coordinates of m = [5 −8 01] with respect to this basis, we must first write the basis elements as matrices.

Therefore, we have b = {[−1 −3 0],[0 −1 1],[0 0 −2]}

The given matrix is  m = [5 −8 01]

To obtain the coordinates of m with respect to the basis b, we perform the following steps. In this context, we are trying to represent the given matrix in terms of the basis matrices.

As a result, we have to utilize the solution for the linear system that is formed by combining the basis matrices and the given matrix.

We set up a linear system of equations with the basis matrices as coefficients and the given matrix as a constant vector.

In this case, we have [b1 b2 b3][x1 x2 x3]T = m

This can be expressed in the following matrix equation form.

[−1 −3 0 0 −1 1 0 0 −2][x1 x2 x3]T = [5 −8 01]

Rearranging the equation, we have

−x1 − 3x2 + 5 = 0

− x2 − 8x3 − 8 = 0

x2 + x3 = 1 − 2x3 = 0

Solving the system of equations, we get

x1 = −7/3

x2 = −1/3

x3 = −1/2

Thus, the coordinates of m with respect to the basis b are  x = [x1 x2 x3]T = [−7/3 −1/3 −1/2]T

The third container has a mixture that is 48% acid.

A mixture is a combination of two or more substances that are not chemically combined with each other. In a mixture, each substance retains its own chemical properties and can be physically separated from the other substances in the mixture.

Let's assume that the first container has a volume of V, so the second container has a volume of 1.5V since it is 50% larger than the first container.

The amount of acid in the first container is 0.3V (since the mixture is 30% acid), and the amount of acid in the second container is 0.6(1.5V) = 0.9V (since the mixture is 60% acid).

When the two containers are emptied into the third container, the total volume of the mixture in the third container is V + 1.5V = 2.5V, and the total amount of acid in the mixture is 0.3V + 0.9V = 1.2V.

Therefore, the percent of acid in the third container is:

(1.2V / 2.5V) x 100% = 48%

So the third container has a mixture that is 48% acid.
