Answers

Answer:

Option C, 20 is the answer.

Step-by-step explanation:

Let g(x) = 2x and h(x) = x² + 4

We have to evaluate (h ο g) ( -2 )

Since ( h ο g )x = h [ g(x) ]

                       = ( 2x)² + 4

                       = 4x² + 4

( h ο g ) ( -2 )  = 4 ( -2 )² + 4

                       = 4 × 4 + 4

                       = 16 + 4

                       = 20

Answers

Answer:

22 - 3 × 6 + 52 = 56

Step-by-step explanation:

Multiply

3×6 = 18

22-18+52

Add and subtract

22-18 = 4

4+52 = 46

Answer:

56

Step-by-step explanation:

To solve we must use the order of operations which is PEMDAS.

P-Parenthesis

E-Exponents

M-Multiplication

D-Division

A-Addition

and S-Subtraction

First we multiply -3 and 6 which gives us -18. So our equation is now 22-18+52.

Next we do addition. -18+52 is 34, plus 22 gives us 56.

Colin’s piano lesson is 45 minutes, or Three-fourths of an hour, long. If he practices 6 different songs and spends an equal amount of time on each song, what fraction of an hour does he spend practicing each song?

Answers

Answer:

Colin spends 1/8 of an hour practicing each song

Step-by-step explanation:

Colin's piano lesson is 3/4 of an hour, long.

In that period, he practices 6 different songs, spending an equal amount of time on each one.

This means that each song gets the sixth part of the lesson duration. The fraction that expresses that amount is:

[tex]\displaystyle \frac{\frac{3}{4}}{6}=\frac{3}{24}=\frac{1}{8}[/tex]

Colin spends 1/8 of an hour practicing each song

You have two cubes that
you fill with water
to make ice cubes. The first cube has a side
length of 3 units. The second cube has a
side length of 5 units. Write an
expression
that you can use to find the total volume of
ice you can make.

Answers

Answer:

V = 3^3 = 5^3

Volume of each cube is side^3. To find the volume of both cubes just add the two volumes together.

Step-by-step explanation: Your welcome.

Answer:

total volume = 152 units³

given:

first cube side: 3 unitssecond cube side: 5 units

volume of cube: side³

using this formula:

total volume = first cube volume + second cube volume

total volume = 3³ + 5³

total volume = 27 + 125

total volume = 152 units³

Answers

Step-by-step explanation:

Let us label these coordinates for our own ease:

A(0,0)

B(0,4)

C(4,5)

Area= [Ax(By-Cy)+Bx(Cy-Ay)+Cx(Ay-By)]÷2

Area = [0(4-5)+0(5-0)+4(0-4)]÷2

Area= [0+0-16]÷2

Area = -8

But since the value can not be negative we have consider a modulus in the formula, thus the value is 8

[tex] \: [/tex]
Don't Spam ​

Answers

Answer:

To Evaluate:

[tex] \\ { \displaystyle{ \rm \lim_{x \to1} \left \{ \frac{ {x}^{4 } - {3x}^{2} + 2 }{ {x}^{3} - {5x}^{2} + 3x + 1} \right \} }}\\ \\[/tex]

Using L'Hospital's Rule

Let f(x) and g(x) be two common functions which are differentiable on an open Interval , at a point a where,

[tex]\\{ \displaystyle{ \lim_{x \to a}{ \rm{f(x)} = { \displaystyle{ \lim_{x \to a}}} \: { \rm{g(x)}} = 0 \: or \: \pm \infty}}}\\ \\[/tex]

Then,

[tex]\\{ \displaystyle{ \lim_{x \to a} \frac{{ \rm{f (x)}}}{{ \rm{g(x)}}} = { \displaystyle{ \lim_{x \to a }}} \frac{{ \rm{f '(x)}}}{{ \rm{g'(x)}}}}}\\ \\[/tex]

As x to 0 , we have:

[tex]\\{ \displaystyle{ \lim_{x \to 1}}} \left( \large\rm\frac{ {x}^{4} - {3x}^{2} + 2 }{ {x}^{3} - {5x}^{2} + 3x + 1} \right) = \frac{0}{0}\\ \\[/tex]

Therefore,

[tex]\\{ \large{ \displaystyle{ \lim_{x \to1}}} \left( \large \rm\frac{ {x}^{4} - {3x}^{2} + 2}{ {x}^{3} - {5x}^{2} + 3x + 1 } \right) = { \displaystyle{ \lim_{x \to1} { \small{\frac{ {4x}^{3} - 6x}{ {3x}^{2} - 10x + 3 }}} = { \small{\frac{4 - 6}{3 - 10 + 3} }} = - \frac{2}{ - 4} = - \frac{1}{2} }}}\\ \\[/tex]

Hence,

[tex]\\{ \displaystyle{ \lim_{x \to1}{\rm{ \left( \frac{ {x}^{4} - 3 {x}^{2} + 2 }{ {x}^{3} - 5 {x}^{2} + 3x + 1 } \right) = { \boxed{ \red{ - \frac{1}{2} }}}}}}}\\ \\[/tex]

Without using L'Hopital's rule:

Factorize the numerator.

[tex]x^4 - 3x^2 + 2 = (x^2 - 2) (x^2 - 1) = (x^2 - 2) (x + 1) (x - 1)[/tex]

Factorizing cubics is usually a bit trickier. But we know x = 1 makes the denominator vanish, so x - 1 is a factor of the cubic. So for some constants a and b,

[tex]x^3 - 5x^2 + 3x + 1 = (x - 1)^3 + a(x - 1)^2 + b(x - 1)[/tex]

Expanding the right side gives

[tex]x^3 - 5x^2 + 3x + 1 = x^3 + (a - 3)x^2 + (-2a + b + 3)x + a - b - 1[/tex]

Then

[tex]a - 3 = -5 \implies a = -2[/tex]

[tex]-2a + b + 3 = 3 \implies b = -4[/tex]

So we rewrite the limit as

[tex]\displaystyle \lim_{x\to1} \frac{x^4 - 3x^2 + 2}{x^3 - 5x^2 + 3x + 1} = \lim_{x\to1} \frac{(x^2 - 2) (x + 1) (x - 1)}{(x-1)^3 - 2(x-1)^2 - 4(x-1)}[/tex]

x is approaching 1 so x ≠ 1 and we can cancel out factors of x - 1 :

[tex]\displaystyle \lim_{x\to1} \frac{x^4 - 3x^2 + 2}{x^3 - 5x^2 + 3x + 1} = \lim_{x\to1} \frac{(x^2 - 2) (x + 1)}{(x-1)^2 - 2(x-1) - 4}[/tex]

The simplified limand is continuous at x = 1, so we can now evaluate the limit by direct substitution.

[tex]\displaystyle \lim_{x\to1} \frac{x^4 - 3x^2 + 2}{x^3 - 5x^2 + 3x + 1} = \frac{(1^2 - 2) (1 + 1)}{(1-1)^2 - 2(1-1) - 4} = -\frac24 = \boxed{-\frac12}[/tex]

The revenue, in thousands of dollars, of a new flavor of liquor is given below as function of the number of gallons (in hundreds), x, sold:


[tex]r(x) = 50x - {x}^{2} [/tex]
What is the maximum revenue? Use units​

Answers

Answer:

  $625,000

Step-by-step explanation:

The maximum revenue will be found where the derivative of the revenue function is zero.

  r'(x) = 50 -2x = 0

  50 = 2x

  x = 25

When 2500 gallons are sold, the revenue is ...

  r(25) = 50(25) -25(25) = (50 -25)(25) = 25(25) = 625 . . . thousands

The maximum revenue is $625,000.

(x - 4)^2 = 9

Step-by-step explanation:

Completing the square

x^2 - 8x + 7 = 0x^2 - 2*4x + 16 - 9 = 0(x^2 - 2*4x + 4^2) = 9 (x - 4)^2 = 9

The blanks are

- 4 and 9

Answer:

(x^2-4)^2 = 9

Step-by-step explanation:

First, isolate the constant:

x^2-8x = -7

Then, since (a-b)^2 = a^2-2ab+b^2, you should add 16(4^2) to both sides:

x^2-8x+16 = 9

Now, we can rewrite the right-hand side as (a-b)^2:

(x-4)^2 = 9
