What two number adds to 10 but multiply to 16

2 answers:

8 0

Let 2 nos. be x & y

x + y = 10

x * y = 16

from 1st eqn, y = 10 - x

substituting in 2nd eqn

x * (10 - x) = 16

10x - x^2 = 16

x^2 - 10x + 16 = 0

(x - 8)(x - 2) = 0

x = 8 or x =2

y = 10 - 8 = 2 or 10 - 2 = 8

so the two numbers are 2 and 8

8 and 2 because 2+8=10 and 2 times 8 =16

When completing an online shopping transaction, a typical shopper takes 9 seconds to select each product and another 8 seconds t

katrin [286]

Answer:

In 26 seconds to complete a transaction, 2 products are being purchased.

Step-by-step explanation:

Here, time taken to select 1 item = 9 seconds

Time taken in all to check out = 8 seconds

Here, time taken to shop = 26 seconds

Now as check out process takes 8 seconds , so the

Time left to ACTUALLY SHOP = Total Time - Time Used to check out

= 26 seconds = 8 seconds = 18 seconds

Shopping of 1 item = 8 seconds

Shopping of 2 items = 2 x ( Time taken in 1 item) = 2 x 9 = 18 seconds

So, in 18 seconds, 2 clothing item can be selected.

Hence,in 26 seconds to complete a transaction, 2 products are being purchased.

if 7 < 5, then 5 < 3 state the inverse, contrapositive, and converse of each conditional statement. then indicate whether

RUDIKE [14]

The given conditional statement is : If 7<5, then 5<3.

Inverse: If 7≥5 then 5≥3 (The inverse is true)

Contrapositive: if 5≥3 then 7≥5 (The contrapositive is true)

Converse: if 5<3 then 7<5 (The converse is true)

From the properties of conditional statement we know that:

if p→q then

inverse is : $\backsim p \rightarrow \backsim q$

contrapositive: $\backsim q \rightarrow \backsim p$

Converse: $q \rightarrow p$

Let us elaborate on the above conditions. Let us take two statement p and q such that If p happens then q also happens.

The inverse of a conditional statement is given as "if not p then not q"the converse is given as "if q then p"The contrapositive of the statement states "if not q then not p"

The following statements can be used for converting the conditional statements to its inverse, converse or contrapositive.

A point P(x,y) moves along the graph of the equation y = x3 + x2 + 2. The x-values are changing at the rate of 2 units per secon

CaHeK987 [17]

Using implicit differentiation, it is found that y is changing at a rate of 10 units per second.

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

The equation is:

$y = x^3 + x^2 + 2$

Applying implicit differentiation in function of t, we have that:

$\frac{dy}{dt} = 3x^2\frac{dx}{dt} + 2x\frac{dx}{dt}$

x-values changing at a rate of 2 units per second means that $\frac{dx}{dt} = 2$
Point Q(1,4) means that $x = 1, y = 4$ .

We want to find $\frac{dy}{dt}$ , thus:

$\frac{dy}{dt} = 3x^2\frac{dx}{dt} + 2x\frac{dx}{dt}$

$\frac{dy}{dt} = 3(1)^2(2) + 2(1)(2) = 6 + 4 = 10$

y is changing at a rate of 10 units per second.
