5 0

Note: In the given expression, it must be 10^4 instead of 19^4.

Given:

The expression is:

(6.31\times 10^5)+(2.6\times 10^4)

To find:

The value of the given expression.

Solution:

We have,

(6.31\times 10^5)+(2.6\times 10^4)

On simplification, we get

=6.31\times 100000+2.6\times 10000

=631000+26000

=657000

=6.57\times 100000

=6.57\times 10^5

Therefore, the value of the given expression in scientific notation is 6.57\times 10^5.

RS = 4x – 9, ST = 19, RT = 80 – 14<br><br> Equation:<br><br> 82 – 14<br><br> RS<br><br> RT
algol13

Step-by-step explanation:

The expressions are not properly written

Given

RS = 4x – 9

ST = 19

RT = 8x – 14

Based on the given parameters, the addition postulate below is true

RS+ST = RT

Substitute

4x-9+19 = 8x-14

collect like terms

4x-8x = -14-19+9

-4x = -33+9

-4x = -24

x = -24/-4

x = 6

Get RS:

RS = 4x-9

RS = 4(6)- 9

RS = 24-9

RS = 15

Get RT:

RT = 8x - 14

RT = 8(6)-14

RT = 48-14

RT = 34

If f(x)= 3x2 and g(x) = x+2, find (f.g)(x).
Paha777 [63]

Step-by-step explanation:

f(x) = 3 {x}^{2}  \: and \: g(x) = x + 2 \\ (f.g)(x)  \\ = f(x).g(x) \\  = 3 {x}^{2} .(x  + 2) \\ \red{ \boxed{ \bold{  \therefore f(x).g(x)= 3 {x}^{3}  + 6 {x}^{2} }}} \\

Let p: A number is greater than 25.
maria [59]
We are given that:
p is greater than 25, this means that p>25
p ∈ ]25,∞[ ...........> interval I

q is less than 35, this means that q<35
q ∈ ]-∞,35[ ...........> interval II

The given condition <span>p ∧ q is true means that (p and q) is true. In other word, their intersection is true.
Therefore, the final result would be the intersection between the two intervals (interval I and interval II)

Bases on the above, the final answer would be:
</span>]-∞,35[  ∧ ]25,∞[  which is ]25,35[<span>

</span>
