Debra's two area baking plates are 17 square inches different in size.

The area surrounding a shape forms its perimeter. Area is a unit of measurement for interior space. Surface area is a measurement of a solid shape's exposed surface, whereas area is a two-dimensional measurement of the size of a flat surface (three-dimensional).

The square baking dish has the following surface area with an 8-inch side length:

Area of first square = (side length)² = 8² = 64 square inches

Similarly, the surface area of a square baking dish with 9-inch sides is:

Area of second square = (side length)² = 9² = 81 square inches

Difference in area = |Area of second square - Area of first square|

Difference in area = |81 - 64|

Difference in area = 17 square inches

The coordinates of the centroid (,)(△) of triangle ABC are (-1, 8/3).

To find the coordinates of the centroid, we can use the formula:

(x, y) = ((x1 + x2 + x3)/3, (y1 + y2 + y3)/3)

where (x1, y1), (x2, y2), and (x3, y3) are the coordinates of the vertices A, B, and C, respectively.

Plugging in the coordinates of A (0, 4), B (0, 2), and C (-3, 2), we get:

(x, y) = ((0 + 0 - 3)/3, (4 + 2 + 2)/3) = (-1, 8/3)

In a two-dimensional plane, the centroid of a triangle is the point where the three medians of the triangle intersect. A median is a line segment drawn from a vertex of the triangle to the midpoint of the opposite side. The centroid divides each median into two segments, with the ratio of the length of the segment closer to the vertex to the length of the segment closer to the opposite side being 2:1.

In a three-dimensional space, the centroid of a solid can be found by dividing the solid into smaller parts, finding the centroid of each part, and then averaging them. The centroid of a solid is the point where the lines connecting the centroids of each part intersect.

Answer:

do you have like any picture of a graph?

The graph of this function is a sine curve with amplitude 3√2 and phase shift π/4.

The k cos(ϕ) would be 3 and k sin(ϕ) would be 3.

The combined sound is given by:

f(t) = f1(t) + f2(t)

f(t) = 3 sin(t) + 3 cos(t)

To find k and ϕ, we can use the following trigonometric identity:

k sin(t + ϕ) = k sin(t) cos(ϕ) + k cos(t) sin(ϕ)

Comparing this with the equation for f(t), we can see that:

k cos(ϕ) = 3

k sin(ϕ) = 3

Squaring both equations and adding them gives:

k^2 = 3^2 + 3^2 = 18

k = √18 = 3√2

Dividing the two equations gives:

tan(ϕ) = 3/3 = 1

ϕ = π/4

Therefore, the combined sound has the form:

f(t) = 3√2 sin(t + π/4)

Yes, the binomial 2x+3 is a factor of the given polynomial P(x)=2x^(3)+3x^(2)-2x-3. We can verify this by using synthetic division.

First, we need to find the zero of the binomial, which is -3/2. Then, we can use synthetic division to divide the polynomial by the binomial.

Here are the steps for synthetic division:

1. Write the coefficients of the polynomial in a row: 2  3  -2  -3
2. Write the zero of the binomial to the left of the row: -3/2 | 2  3  -2  -3
3. Bring down the first coefficient: -3/2 | 2  3  -2  -3
               0  -3   6  -6
               ---------------
               2  0   4   -9
4. Multiply the zero by the first coefficient and write the result below the second coefficient: -3/2 * 2 = -3
5. Add the second coefficient and the result: 3 + (-3) = 0
6. Repeat steps 4 and 5 for the remaining coefficients: -3/2 * 0 = 0, -2 + 0 = -2; -3/2 * -2 = 3, -3 + 3 = 0
7. The final row of numbers represents the coefficients of the quotient: 2x^(2) + 0x + 4, with a remainder of -9.

Since the remainder is not zero, the binomial is not a factor of the polynomial. However, if we divide the polynomial by the binomial using long division, we get the following:

2x^(2) + 4 - (9/(2x+3))

This means that the polynomial can be written as: P(x) = (2x+3)(2x^(2) + 4) - 9

So, the binomial 2x+3 is a factor of the polynomial P(x)=2x^(3)+3x^(2)-2x-3.

Part 1) find sec (theta)

we know that

sec (theta)=1/ cos (theta)

cos (theta)=adjacent side angle theta/hypotenuse

adjacent side angle theta=5

hypotenuse=13

so

cos (theta)=5/13

sec (theta)=1/(5/13)-------> sec (theta)=13/5

the answer Part 1) is

sec (theta) = 13/5

Part 2)simplify sec(theta)*cos (theta)

sec (theta)=13/5

cos (theta)=5/13

so

sec(theta)*cos (theta)=(13/5)*(5/13)----> 1

the answer part 2) is 1

Part 3)simplify cot(theta)/cos(theta)

cot (theta)=5/12

cos (theta)=5/13

so

cot(theta)/cos(theta)=(5/12)/(5/13)----> 13/12

we know that

sin (theta)=opposite angle theta/hypotenuse

opposite side angle theta=12

hypotenuse=13

sin (theta)=12/13

csc (theta)=1/sin (theta)------> csc (theta)=1/(12/13)----> csc (theta)=13/12

therefore

cot(theta)/cos(theta)=csc (theta)

the answer Part 3) is

csc (theta)

Part 4)simplify cot(theta)*sin(theta)

cot (theta)=5/12

sin (theta)=12/13

so

cot(theta)*sin(theta)=(5/12)*(12/13)----> 5/13

cos (theta) =5/13

Answer:$72 Total

Step-by-step explanation:

20%=1/5

1/5 + 5/5(total) = 6/5

60 * 6/5 = $72

The given information tells us that the sin a is equal to 5/13, and that 0 is less than a, which is less than π/2. Therefore, the exact function value for sin a is 5/13 and the value for a is approximately  5/12.

We are given that sin(a) = 5/13 and 0 < a < π/2. We can use the Pythagorean identity cos²(a) + sin²(a) = 1 to find cos(a):

cos²(a) + sin²(a) = 1

cos²(a) + (5/13)² = 1

cos²(a) = 1 - (5/13)²

cos²(a) = 144/169

cos(a) = ± 12/13

Since 0 < a < π/2, we know that cos(a) > 0. Therefore, cos(a) = 12/13. We can use the definition of tangent to find tan(a):

tan(a) = sin(a)/cos(a) = (5/13)/(12/13) = 5/12

Therefore, the exact function value we were asked to find is tan(a) = 5/12.

The volume of the parallelepiped is 15.

To determine the volume of the parallelepiped with one vertex at the origin and the three vertices adjacent to it at (3,1,-1), (6,7,1), and (-6,8,9), we need to find the scalar triple product of the three vectors formed by these vertices. The scalar triple product is given by the determinant of the matrix formed by the three vectors:
\[ \begin{vmatrix} 3 & 1 & -1 \\ 6 & 7 & 1 \\ -6 & 8 & 9 \end{vmatrix} \]
Expanding the determinant, we get:
\[ \begin{aligned} \text { Volume } &=3\left( \begin{vmatrix} 7 & 1 \\ 8 & 9 \end{vmatrix} \right)-1\left( \begin{vmatrix} 6 & 1 \\ -6 & 9 \end{vmatrix} \right)-1\left( \begin{vmatrix} 6 & 7 \\ -6 & 8 \end{vmatrix} \right) \\ &=3(63-8)-1(54+6)-1(48+42) \\ &=165-60-90 \\ &=15 \end{aligned} \]

The requried value of the expression [tex]\sum_{n=11}^{30}n-\sum_{n=1}^{10}n[/tex] is 355.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression.

Here,
To evaluate the expression:

[tex]\sum_{n=11}^{30}n-\sum_{n=1}^{10}n[/tex]

we can first simplify each summation separately and then subtract the second summation from the first.

[tex]\sum_{n=11}^{30}n[/tex]= 11 + 12 + 13 + ... + 29 + 30

We can use the formula for the sum of an arithmetic series to simplify this expression:

S = (n/2)(a + l)

In this case, a = 11, l = 30, and n = 20 (since we're summing 20 terms).

So, we have:

S = (20/2)(11 + 30)

S= 410

Similarly,

[tex]\sum_{n=1}^{10}n[/tex] = 1 + 2 + 3 + ... + 9 + 10

S = 55

Finally, we can subtract the second summation from the first:

= 410 - 55 = 355
