1 answer:
blsea [12.9K]2 years ago
5 0

Answer:

The explicit formula of that sequence is T - 5

Step-by-step explanation:

Let T represent each term in the sequence. So now try replacing T with each term in the sequence. Like this ;

7 - 5 = 2

2 - 5 = -3

-3 - 5 = -8

hope this helps

hanna shops for socks that cost $2.99 for each pair and blouses that cost $12.99 each. let x represent the number of pairs of so
blsea [12.9K]
In this item, we let x be the number of pairs of socks and y be the number of blouses that were purchased by Hanna. The total amount that is spent for the socks and blouses are 2.99x and 12.99y, respectively. The equation that would best describe the given scenario is,
                              2.99x + 12.99y = 43.92

The masses mi are located at the points Pi. Find the moments Mx and My and the center of mass of the system. m1 = 4, m2 = 3, m3
viva [34]

Answer:

M_x= 8

M_y = 6

Therefore the co-ordinate of the center of mass is = (\frac{4}{5},\frac{3}{5})

Step-by-step explanation:

Center of mass: Center of mass of an object is a point on the object. Center of mass is the average position of the system.

Center of mass of a triangle is the centriod of a triangle.

Given that m₁= 4, m₂=3, m₃=3 and the points are P₁(2,-3), P₂(-3,1) and P₃(3,5)

M_x = ∑(mass × x-co-ordinate)

M_y = ∑(mass × y-co-ordinate)

Therefore  

M_x = (4×2)+{3×(-3)}+(3×3)

     =8

M_y = {4×(-3)}+{3×1}+(3×5)

    =6

The x co-ordinate of the center of mass is the ratio of M_x to the total mass.

The y co-ordinate of the center of mass is the ratio of M_y to the total mass.

Total mass (m) = m₁+ m₂+ m₃

                        = 4+3+3

                        =10

The x co-ordinate of the center of mass is \frac {8}{10} = \frac {4}{5}

The y co-ordinate of the center of mass is \frac{6}{10}=\frac{3}{5}

Therefore the co-ordinate of the center of mass is = (\frac{4}{5},\frac{3}{5})

What is the area of a rectangle that is \dfrac1{2} 2 1 ​ start fraction, 1, divided by, 2, end fraction of a meter long and \dfr
sashaice [31]

Answer:

Area = \frac{3}{16} m^2

Step-by-step explanation:

Given

Shape: Rectangle

Length = \frac{1}{2}\ m

Width = \frac{3}{8}\ m

Required

Determine the area of the rectangle;

Area is calculated as thus;

Area = Length * Width

Substitute values for Length and Width

Area = \frac{1}{2} * \frac{3}{8}

Area = \frac{1 * 3}{2 * 8}

Area = \frac{3}{16}

<em>Hence, the area of the rectangle is </em>\frac{3}{16}m^2<em />
