Answer:

700 Dollars

Step-by-step explanation:

The expression for solving this is I = prt

So lets start with P, that is our principal or amount of money we start with, and we want to multiply it by our rate, or r , which is 3.5, so we would do 5000 x 0.035 to get 175, then we multiply that by our time or t, which is 4 years, so 175 x 4 = 700 dollars :D

The first side of a triangle measures 4 in. less than the second side, the third side is 3 in more than the first side, and the

GuDViN [60]

Answer:

5 2/3 inches
S-1

Step-by-step explanation:

(a) Let x represent the length of the first side. Then the second side is (x+4) and the third side is (x+3). The perimeter is ...

x + (x+4) +(x+3) = 15

3x = 8 . . . . collect terms, subtract 7

x = 2 2/3 . . . . divide by 3

The third side is x+3 = 5 2/3 inches.

(b) For this, we are told the second side is S, so we have ...

S = (x+4)

x = S -4 . . . . . subtract 4 to solve for x

Using this in our expression (in part (a)) for the third side, we have ...

third side = (x +3) = (S -4) +3

third side = S -1

If a bored game was originally $25 and it is on sale for $18 , what is the percent discount?

Blizzard [7]

Hi there!

To find the percent discount, we need to divide the new price by the original price without the discount:

18 / 25 = 0.72

Now, we convert this into a percentage, so we can find the <em>percent </em>discount:

0.72 = 72%

Now, we subtract from 100%:

100% - 72% = 28%

So, the answer is 28%.

Hope this helps!

Consider the following. C: counterclockwise around the triangle with vertices (0, 0), (1, 0), and (0, 1), starting at (0, 0)

horsena [70]

Answer:

$\mathbf{r_1 = (t,0) \implies t = 0 \ to \ 1}$

$\mathbf{r_2 = (2-t,t-1) \implies t = 1 \ to \ 2}$

$\mathbf{r_3 = (0,3-t) \implies t = 2 \ to \ 3}$

$\mathbf{\int \limits _{c} F \ dr =\dfrac{11 \sqrt{2}+11}{6}}$

Step-by-step explanation:

Given that:

C: counterclockwise around the triangle with vertices (0, 0), (1, 0), and (0, 1), starting at (0, 0)

a. Find a piecewise smooth parametrization of the path C.

r(t) = { 0

If C: counterclockwise around the triangle with vertices (0, 0), (1, 0), and (0, 1),

Then:

$C_1 = (0,0) \\ \\ C_2 = (1,0) \\ \\ C_3 = (0,1)$

Also:

$\mathtt{r_1 = (0,0) + t(1,0) = (t,0) }$

$\mathbf{r_1 = (t,0) \implies t = 0 \ to \ 1}$

$\mathtt{r_2 = (1,0) + t(-1,1) = (1- t,t) }$

$\mathbf{r_2 = (2-t,t-1) \implies t = 1 \ to \ 2}$

$\mathtt{r_3 = (0,1) + t(0,-1) = (0,1-t) }$

$\mathbf{r_3 = (0,3-t) \implies t = 2 \ to \ 3}$
