Answer:

Rs.380

Step-by-step explanation:

Given data

Price=  Rs 400.

Discount= 5%

Let us find the amount of the discount

=0.05*400

=Rs. 20

Hence the amount that should be paid for it is

=400-20

=Rs.380

What is the value of the expressions below when n = 1.5?<br><br> 5n – (20 + n)
sdas [7]

Answer:

-14

Step-by-step explanation:

if n = 1.5, replace all letters labeled "n" with 1.5

5(1.5) - (20 +1.5)

5 x 1.5 = 7.5

(20+1.5) = 21.5

7.5 - 21.5 = -14

Part A: Yes this is a function because there are no repeated x values. Each x value points to exactly one y output. You can graph each point and the graph will not fail the vertical line test.

<span>----------------------------------------------</span>

Part B: Plug x = 6 into the f(x) function given to get
f(x) = 7x-15
f(6) = 7*6-15
f(6) = 42-15
f(6) = 27
Now compare this with the table. According to the table, when x = 6, the value of y is 14. So the f(x) value is larger than the table value when x = 6

----------------------------------------------

Part C:

Replace f(x) with 6 and solve for x

f(x) = 7x-15
6 = 7x-15
6+15 = 7x-15+15
21 = 7x
7x = 21
7x/7 = 21/7
x = 3

So the final answer, for part C, is x = 3

Find the line integral with respect to arc length ∫C(8x+5y)ds, where C is the line segment in the xy-plane with endpoints P=(7,0
puteri [66]

a. Parameterize C by

\vec r(t)=(1-t)(7,0)+t(0,5)=(7-7t,5t)

with 0\le t\le1

b. The integral is to be computed over the range of the parameter t.

c. The integral has a value of

\displaystyle\int_C(8x+5y)\,\mathrm dS=\int_0^1(8x(t)+5y(t))\|\vec r(t)\|\,\mathrm dt

\displaystyle=\int_0^1(8(7-7t)+5(5t))\|(-7,5)\|\,\mathrm dt

\displaystyle=\sqrt{74}\int_0^1(56-31t)\,\mathrm dt=\boxed{81\sqrt{\dfrac{37}2}}
