A rectangular solid has sides of 7 cm + 9 cm + 11 cm what is its surface area

alina1380 [7]

Your answer would be: 693.

Explanation:

When finding the area in a problem use L×W×H.

That being said, you now have to multiply the L×W×H (7x9x11)

7 × 9 × 11 = 693

So the answer would be 693 because, if you are finding an area you use L×W×H to find your area.

State the domain restriction(s) in interval notation of \displaystyle f\left(g\left(x\right)\right)f(g(x)) given: \displaystyle

DENIUS [597]

Answer:

The interval notation for the domain is $[\frac{23}{3},\infty ]$ .

Step-by-step explanation:

Consider the provided information.

It is given that $\:f\left(x\right)=\sqrt{3x-2},\:\text{ and }\:g\left(x\right)=x-7$

We need to find the value of $f\left(g\left(x\right)\right)$ .

Put the value of g(x) in $f\left(g\left(x\right)\right)$ .

$f\left(g\left(x\right)\right)=f(x-7)$ ....(1)

Now, put x=x-7 in $\:f\left(x\right)=\sqrt{3x-2}$

$\:f\left(x-7\right)= \sqrt{3(x-7)-2}$

$\:f\left(x-7\right)= \sqrt{3x-21-2}$

$\:f\left(x-7\right)= \sqrt{3x-23}$

From equation 1.

$f\left(g\left(x\right)\right)=\:f\left(x-7\right)= \sqrt{3x-23}$

The domain of the function is the set of input values for which a function is defined.

Here, the value of $3x-23$ should be greater or equal to 0 as the square root of a negative number is not real.

Domain= $3x-23\geq0$

$x\geq\frac{23}{3}$

The value of x is all real number greater than $\frac{23}{3}$ .

Hence, the interval notation for the domain is $[\frac{23}{3},\infty ]$ .

Select the correct answer from the drop-down menu. A whole number is 6 more than 2 times another number. The sum of the two numb

olya-2409 [2.1K]

Answer:

$x = \{13,14\}$

Step-by-step explanation:

Given

$x + 2x + 6 < 50$

Required

True values of x

We have:

$x + 2x + 6 < 50\\$

$3x + 6 < 50$

Collect like terms

$3x < 50-6$

$3x < 44$

Divide both sides by 3

$x < 44/3$

$x < 14.67$

This means that x has a value lesser than 14.67.

Hence, the valid values are:

$x = \{13,14\}$
