The right answer is 60. M<1 + M<2 + M<3 = 180 
                                      50    + 70  + M<3 = 180 
                                               120  + M<3 = 180   
                                                120 -             -120 
                                               ____               ___ 
                                                            M<3  =     60

The fourth term of an Arithmetic Sequence is equal to 3 times the first term, and the seventh term exceeds twice the third term
11Alexandr11 [23.1K]

Answer:

The first term is 3. The common difference is 2.

Step-by-step explanation:

The first term is x.

The common difference is d.

The second term is x + d.

3rd term: x + 2d

4th term: x + 3d

7th term: x + 6d

"The fourth term of an Arithmetic Sequence is equal to 3 times the first term"

x + 3d = 3 * x       Eq. 1

"the seventh term exceeds twice the third term by 1"

x + 6d = 2(x + 2d) + 1       Eq. 2

Simplify Eq. 1:

2x = 3d

Simplify Eq. 2:

x + 6d = 2x + 4d + 1

x = 2d - 1

Multiply both sides of the last equation by 2.

2x = 4d - 2

2x = 3d   (simplified Eq. 1)

Since 2x = 2x, then the right sides are equal.

3d = 4d - 2

d = 2

2x = 3d

2x = 3(2)

2x = 6

x = 3

Answer: The first term is 3. The common difference is 2.

If you vertically compress the linear perent function, F(x) = x, by multiplying by 1\2
andrezito [222]

Answer: y=\dfrac12 x .

Step-by-step explanation:

We know that a f (x)  compresses f(x) vertically such that

  • if 0 < a < 1 (a fraction), the graph is compressed vertically by a factor of a units.
  • if a > 1, the graph is stretched vertically by a factor of a units.

If we vertically compress the linear parent function, F(x) = x, by multiplying by \dfrac12.

Then, the equation of the new function is y=\dfrac12 F(x)=\dfrac12 x .

i.e. y=\dfrac12 x .

An average tub bath uses 8 gallons of water and an average shower uses 6 gallons. to provide baths for 60 people, how much more
viva [34]
<span>You need (8-6) 2 extra gallons to take a bath. With sixty people bathing, you'll need 60*2=120 extra gallons to meet the extra demand for water. Alternatively, you could note that 60 bathers*8 gallons per bath=480 gallons of water would be used for 60 baths and 60*6=360 needed for showers. The difference would be 480-360=120 gallons.</span>
