Answer:

-15

Step-by-step explanation:

start from the inside and go out.

So first plug in -3 into g(x)

g(-3) = -3 - 7 = -10

then plug in -10 into f(x)

f(-10) = 2(-10) + 5 = -15

so f(g(x)) = -15

Answer:

Step-by-step explanation:

f(x) = 2x + 5

g(x) = x − 7

To find f(g(x)) substitute g(x) into f(x) that's replace every x in f(x) by g(x)

That's

f(g(x)) = 2(x - 7) + 5

= 2x - 14 + 5

f(g(x)) = 2x - 9

When x = - 3

Substitute - 3 into f(g(x))

That's

Step-by-step explanation:

The volume constrained both by the cone and the sphere is [tex]21.905\pi[/tex] cubic units.

The volume of a solid in cylindrical coordinates ([tex]V[/tex]) can be determined by the following triple integral:

[tex]V = \iiint dz\,r\,dr\,d\theta[/tex] (1)

The solid is constrained by the following equations in cylindrical coordinates:

Sphere

[tex]r^{2}+z^{2} = 32[/tex] (2)

Cone

[tex]z = r[/tex] (3)

The integration limits can be identified by using the following intervals:

[tex]z \in [0, +\sqrt{32-4^{2}}][/tex], [tex]r \in [0,4][/tex], [tex]\theta \in [0,2\pi][/tex]

[tex]V = \int\limits_{0}^{2\pi}\int\limits_{0}^{4}\int\limits_{0}^{+\sqrt{32-r^{2}}} dz\,r\,dr\,d\theta[/tex] (4)

Now we proceed to integrate the expression thrice:

[tex]V = \int\limits_{0}^{2\pi}\int\limits_{0}^{4}\sqrt{32-r^{2}}\,r\,dr\,d\theta = 10.952\int\limits_{0}^{2\pi}\,d\theta = 21.905\pi[/tex]

Answer:

b. $7,482.

Step-by-step explanation:

20,403 nets $5,996,106 after 35 years.

7,482 nets $2,198,837 after 35 years.

$7,482 is over 2 million and the smallest amount, so you don't have to solve for the other ones.

The real amount that must deposit each year to achieve your goal is $16,017 option (c) is correct.

An investment is a payment made to acquire the securities of other firms with the intention of making a profit.

First, we will calculate the real rate of interest:

r = [(1+nominal rate)/(1+inflation rate)] - 1

Nominal rate = 9.94% = 0.094

Inflation rate = 3.2% = 0.032

r = [(1+0.094)/(1+0.032)] - 1

After calculating,

r = 0.0653 or 6.53%

Deposit amount each year:

Future value = PV[(1+r)ⁿ - 1]/(r)

2000000 = PV[(1+0.0653)³⁵ - 1]/(0.0653)

After calculating,

PV = $16020.544

The value $16020.544 is near the $16,017.

Thus, the real amount that must deposit each year to achieve your goal is $16,017 option (c) is correct.

Answer:

There are 10 $1 bills and 7 $5 bills

Step-by-step explanation:

7($5 bills) x 5

=35

7+3 (3 more $1 bills)

=10

10+35

=45

Answer:

$1: 10

$5: 7

Step-by-step explanation:

To find out how many of each bill is in the cash box, create an expression

x = the dollar bills

This makes the $5 bills 5x and the $1 bills x (this can also be 1x)

When it says "The number of $1 bills is 3 more than the number of $5 bills" This means that the number of $1 is x + 3 and the number of $5 is 5x

When you put it together the expression will be x + 3 + 5x = 45

First add x and 5x, making it 6x

Next subtract 3 from each side, which makes the equation 6x = 42

Lastly, divide 6 from each side, this means that x = 7

To find out how many bills there are substitute 7 wherever there is an x

This mean that the number of $1 is 7 + 3 (10), and the number of $5 bills are 5x7 (35), but its just 7 because they are $5 each

Answer:

180

Step-by-step explanation:

The original price is the quotient between $120 and 2/3, we get:

P = $180

We know that 2/3 of the original price is $120, then to get the original price, we need to take the quotient between $120 and 2/3.

[tex]P = \frac{\$120}{2/3} = (3/2)*\$ 120[/tex]

By taking that quotient we will see that the original price of the coat is:

[tex]P = (3/2)*\$120 = $180[/tex]

Answer: ps = 1012.5

Therefore the producers' surplus for the supply equation at the indicated unit price p is 1012.5

Step-by-step explanation:

Given that;

p = 120 + q ; p = 165

Now to find the producer's surplus for supply equation p=f(q) at the indicated unit price; we find p

so from p = 120 + q ; p = 165, if we substitute for q

120 + q = 165

q = 165 - 120 = 45

so

ps = ⁴⁵∫₀ ( 165 - (120+q) dq

ps = ⁴⁵∫₀ ( 45 - q) dq

USING THE EXPRESSION [ xⁿdx = xⁿ⁺¹ / n+1]

ps =  [45q - q²/2]₀⁴⁵

ps = [45(45) - 45²/2] [45(0) - (0)²/2]  

ps =  [2025 - 1012.5] - [0]

ps = 1012.5

Therefore the producers' surplus for the supply equation at the indicated unit price p is 1012.5

[tex](y+4)(x-4)[/tex]

Step-by-step explanation:

Given the expression:

[tex]xy-4y+4x-16[/tex]

[tex](xy-4y)+(4x-16)[/tex]

Take the common factor

[tex]y(x-4)+4(x-4)[/tex]

[tex](y+4)(x-4)[/tex]

The factored expression is (x - 4)(y + 4).

To factor the expression xy - 4y + 4x - 16 by grouping, we first group the terms in pairs and look for common factors:

xy - 4y + 4x - 16

Now, let's factor by grouping:

Step 1: Group the terms in pairs.

(xy - 4y) + (4x - 16)

Step 2: Factor out the common factor from each group.

In the first group, we can factor out "y" from the two terms:

y(x - 4)

In the second group, we can factor out "4" from the two terms:

4(x - 4)

Step 3: Notice that both groups have a common factor of (x - 4). Factor it out.

(x - 4)(y + 4)

So, the factored expression is (x - 4)(y + 4).

Answer:

A. 8.3

B.18.7

C. 10.4

D. 1.04

Step-by-step explanation:

p(x) = 0.03x² + 0.56x + 6.35

A. Determination of p(3)

p(x) = 0.03x² + 0.56x + 6.35

x = 3

p(3) = 0.03(3)² + 0.56(3) + 6.35

p(3) = 0.03(9) + 1.68 + 6.35

p(3) = 0.27 + 1.68 + 6.35

p(3) = 8.3

B. Determination of p(13)

p(x) = 0.03x² + 0.56x + 6.35

x = 13

p(13) = 0.03(13)² + 0.56(13) + 6.35

p(13) = 0.03(169) + 7.28 + 6.35

p(13) = 5.07 + 7.28 + 6.35

p(13) = 18.7

C. Determination of p(13) – p(3)

From A and B above,

p(13) = 18.7

p(3) = 8.3

p(13) – p(3) = 18.7 – 8.3

p(13) – p(3) = 10.4

D. Determination of p(13) – p(3) / 13 – 3

From C above,

p(13) – p(3) = 10.4

p(13) – p(3) / 13 – 3 = 10.4/ 13 – 3

Answer:

[tex]n = 241[/tex]

Step-by-step explanation:

Given

[tex]5x^2 + nx + 48[/tex]

Required

Determine the highest value of n

From the given equation, 5 is a prime number;

So, the factors of x² is 5x and x or -5x and -x

Since [tex]5x^2 + nx + 48[/tex] has all shades of positive terms, we'll make use of 5x and x

The factorized expression can then be:

[tex](5x + a)(x + b)[/tex]

Open the brackets

[tex]5x^2 + ax + 5bx + ab[/tex]

Equate this to the given expression

[tex]5x^2 + ax + 5bx + ab = 5x^2 + nx + 48[/tex]

[tex]5x^2 + (a + 5b)x + ab = 5x^2 + nx + 48[/tex]

By direct comparison;

[tex]5x^2 = 5x^2[/tex]

[tex](a + 5b)x = nx[/tex]

[tex]a + 5b = n[/tex]  ---- (1)

[tex]ab = 48[/tex] --- (2)

From (2) above, the possible values of a and b are:

[tex]a = 1, b = 48[/tex]

[tex]a = 2, b = 24[/tex]

[tex]a = 3, b = 16[/tex]

[tex]a = 4, c = 12[/tex]

[tex]a = 6, b = 8[/tex]

[tex]a = 8, b = 6[/tex]

[tex]a = 12, b = 4[/tex]

[tex]a = 16, b = 3[/tex]

[tex]a = 24, b = 2[/tex]

[tex]a = 48, b = 1[/tex]

Of all these values; the value of a and b that gives the highest value of n is;

[tex]a = 1, b = 48[/tex]

So;

Substitute 1 for a and 48 for b in (2) [tex]a + 5b = n[/tex]

[tex]1 + 5 * 48 = n[/tex]

[tex]1 + 240 = n[/tex]

[tex]241 = n[/tex]

[tex]n = 241[/tex]

Hence, the largest value of n is 241

Answer:

Step-by-step explanation:

The two factors of $5x^2+nx+48$ must be in the form $(5x+A)(x+B)$. $A$ and $B$ must be positive integers to form the largest value of $n$. Therefore, $AB=48$ and $5B+A=n$. To form the largest value of $n$, $B$ must equal $48$. Therefore, $A=1$. \[5B+A=5(48)+1=\boxed{241}\]

Answer:

the answer is 117/500 hop this helps:)

Step-by-step explanation:

0.234 = 117 / 500

as a fraction

To convert the decimal 0.234 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

0.234 = 0.234/1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 3 numbers after the decimal point, we multiply both numerator and denominator by 1000. So,

0.234/1

= (0.234 × 1000)

(1 × 1000)

= 234

1000

.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(234,1000) = 2. So,

(234÷2)

(1000÷2)

= 117/500

when reduced to the simplest form.
