Answer:

5

35

56

Step-by-step explanation:

8 x 7 = 56

Subtract 21 (3x7) from 56 (8x7) to get 35

Divide 35 by the given value 7 to get 5

5 x 7 = 35

35 + 21 = 56

the width of a rectangle is 9m less than it's legnth if the perimeter of the rectangle is 54m find the legnth of the garden​
Nata [24]

Perimeter of rectangle = 2(l+w)

So, 54cm = 2(l+9cm)

=> 54cm = 2l + 18cm

=> 54cm - 18cm = 2l

=> 36cm = 2l

=> 36cm/2 = l

=> 18cm = l

Svetradugi [14.3K]

Answer:

1. V(t) = -32500t + 245000

a. The slope of the function is m = -32500, and it means the change in the value of V(t) for each unitary change in the value of t.

b. The V-intercept is b = 245000, and it means the value of V(t) when t = 0, that is, the inicial value of V(t).

c. The formula is: V(t) = -32500t + 245000

2. t-intercept: t = 7.5385

The t-intercept means when the function V(t) will be zero, that is, the truck has no value anymore.

3. Graph in the image attached.

4. The domain is t = [0, 7.5385] and the range is V(t) = [245000, 0].

5. V(8) = -15000

It means the price the truck will have after 8 years. It does not make sense, because the truck can't have a negative price.

6. After 3.6 years.

7. Between 3.23 years and 5.63 years.

Step-by-step explanation:

1.

The inicial value is 245,000, and each year the value decreases 32,500, so we can write the equation:

V(t) = -32500t + 245000

a. The slope of the function is m = -32500, and it means the change in the value of V(t) for each unitary change in the value of t.

b. The V-intercept is b = 245000, and it means the value of V(t) when t = 0, that is, the inicial value of V(t).

c. The formula is: V(t) = -32500t + 245000

2.

To find the t-intercept we just need to use V(t) = 0 and then find the value of t:

0 = -32500t + 245000

32500t = 245000

t = 7.5385

The t-intercept means when the function V(t) will be zero, that is, the truck has no value anymore.

3.

The graph of the function is in the image attached.

4.

The domain is t = [0, 7.5385] and the range is V(t) = [245000, 0].

5.

V(8) = -32500*8 + 245000 = -15000

It means the price the truck will have after 8 years. It does not make sense, because the truck can't have a negative price.

6.

128000 = -32500t + 245000

32500t = 117000

t = 3.6

After 3.6 years.

7.

62000 = -32500t + 245000

32500t = 183000

t = 5.6308

140000 = -32500t + 245000

32500t = 105000

t = 3.2308

Between 3.23 years and 5.63 years.
