Answer:

5.74

Step-by-step explanation:

fx=5(x+4)-6

f(19)=5(19+4)-6

19f=5(23)-6

19f=115-6

19f=109

f=109÷19

f=5.74 or 19 14/19

Answer:

  3.  DF = 15

  4.  (x +y +2)(x +y +3)

  5. Tuesday

Step-by-step explanation:

3. The angle congruence tells you the triangles are similar. Corresponding sides have a ratio of 5/4:

  DE/AB = 10/8 = 5/4

  EF/BC = 12.5/10 = 5/4

  DF/AC = ?/12 = 5/4

Multiplying by 12, we find ...

  DF = 12(5/4) = 15

__

4. The first three terms look like (x+y)². The next two look like 5(x+y). So we can group terms to make the expression look like ...

  (x+y)² + 5(x+y) +6

We recognize factors of 6 that sum to give 5 as being 2 and 3, so we can factor this as ...

  (x+y +2)(x+y +3)

__

5. Jan 1 falls on a day of the week that is the first of 3 days of which there are 5 in the month.

There are 3 days between Monday and Friday, but only 2 days between Friday and Monday. Hence the 1st of January must fall on Tuesday that year.

There will be 4 of Fri, Sat, Sun, Mon, and 5 of Tue, Wed, Thu in the month.

A model rocket is launched from the ground with an initial velocity of 160 ft/sec. how long will it take the rocket to reach its
timama [110]
The formula we need is
h(t)=-16t^2+v_0 t+h_0, where <em>v</em>₀ is the starting velocity and <em>h</em>₀ is the initial height.  Using the velocity and starting height from our problem we have
h(t)=-16t^2+160t+0.  The path of this rocket will be a downward facing parabola, so there will be a maximum.  This maximum will be at the vertex of the graph.  To find the vertex we start out with x= \frac{-b}{2a}, which in our case is x= \frac{-160}{2(-16)}= \frac{-160}{-32} = 5.  It will take 5 seconds for the rocket to reach its maximum height.  Plugging this back into our formula gives us
h(5)=-16(5^2)+160(5)+0&#10;\\=-16(25)+800&#10;\\=-400+800=400
The rocket's maximum height is 400 feet.
We set our formula equal to zero to find the time it takes to hit the ground, then we factor:
0=-16t^2+160t+0&#10;\\0=-16t^2+160t&#10;\\0=-16t(t-10)
Using the zero product property, we know that either -16t =0 or t-10=0.  When -16t=0 is at t=0, when the rocket is launched. t-10=0 gives us an answer of t=10, so the rocket reaches the ground again at 10 seconds.

A company purchased a delivery van for $28,000 with a salvage value of $3,000 on September 1, Year 1. It has an estimated useful
Tems11 [23]

Answer:

Depreciation till December 31, Year 1 will be equal to 1,250$

Step-by-step explanation:

Purchasing Cost = 28,000$

Salvage Value = 3,000$

Total Depreciation:

Total Depreciation over 5 years (60 Months) = Purchasing Cost - Salvage Value

Total Depreciation over 5 years (60 Months) = 28,000 - 3,000

Total Depreciation over 5 years (60 Months) = 25,000$

Monthly Depreciation:

Using the unity method we have monthly depreciation by dividing the total depreciation by the total no. of months as below:

Total Depreciation over a single month =25,000/60

Total Depreciation over a single month = 416.67$ (Monthly Depreciation)

Depreciation till December 31, Year 1

As from September 1, Year 1 to December 31, Year 1, its been 3 months therefore total depreciation will be = 3 * Monthly Depreciation

Depreciation till December 31, Year 1 = 3 * 416.67

Depreciation till December 31, Year 1 = 1,250$
