Need help with this

If g(x) = x3 - 5 and h(x) = 2x - 2, find g(h(3))

natima [27]

G(h(3)) simply means g of h of 3
mathematically represented as:
h(3)=2(3)-2 which gives 4
you then substitute 4 with X in g(x)
we then have g(h(3)) where h(3)=4 and X is also =h(3) as
g(4)=4^3-5
=59
•
• • g(h(3))=59

On a certain day, a bakery produced a batch of rolls at a total production cost of $300. On that day, <img src="https://tex.z-dn

Sati [7]

Answer:

The profit of the bakery for this batch of rolls is C. $ 132

Step-by-step explanation:

You know the following this about the problem:

xy=300 is the total cost of the production of the rolls, where x is the cost of the rolls and y is the number of rolls.
Day 1 the bakery sold 4/5 of the rolls at 1.50 its value.
Day 2 the bakery sold 1/5 of the rolls ar 0.8 of the price of Day 1.

$Day1=1.50x\frac{4}{5}y=\frac{3}{2}x\frac{4}{5}y=\frac{6}{5}xy\\Day2=0.8\frac{3}{2}x\frac{1}{5}y=\frac{4}{5}\frac{3}{2}x\frac{1}{5}y=\frac{6}{25}xy$

The total gain of the sales is:

Day 1 + Day 2

$Day1+Day2=\frac{6}{5}xy+\frac{6}{25}xy=\frac{36}{25}xy$

and you know that xy =300, then the total gain is:

$gain=\frac{36}{25}(300)=432$

And the profit is the total gain less the total cost:

Profit = 432-300=132

The surface area of prism 1 is 36 cm²

<h3>Calculating surface area</h3>

From the question, we are to calculate the surface area of prism 1

From the given information, we have that the two hexagon-based prism are similar

Since the shapes are similar, we can write that

(Length of a side in prism 1)² / (Length of the similar side in prism 2)² =

Area of prism 1 / Area of prism 2

From the given information,

Length of a side in prism 1 = 3 cm

Length of the similar side in prism 2 = 8 cm

Area of prism 2 = 256 cm²

Thus,

3² / 8² = Area of prism 1 / 256

Area of prism 1 = (256 × 3²)/ 8²

Area of prism 1 = (256 × 9)/ 64

Area of prism 1 = (2304)/ 64

Area of prism 1 = 36 cm²

Hence, the surface area of prism 1 is 36 cm²

Solve using the substitution method.<br><br><br><br> x + 2y = 9<br><br> x + 3y = 13

Rasek [7]

x + 2y = 9

x + 3y = 13

____________________________________________________________

Solve for x in the first equation. Subtract 2y from both sides.

x = 9 - 2y

____________________________________________________________

Plug x into the second equation.

(9 - 2y) + 3y = 13

Combine like terms.

9 + y = 13

Subtract 9 from both sides.

y = 4

____________________________________________________________

Plug y back into the first equation.

x + 2(4) = 9

x + 8 = 9

Subtract 8 from both sides.

x = 1

____________________________________________________________

x = 1

y = 4

2. If y varies inversely as x and y=0.8 when x = 1.8, find y when x = 4.8.

Aleks04 [339]

Answer:

y=2.13

Step-by-step explanation:

cross multiply

0.8/1.8=y/4.8

4.8*0.8/1.8

3.84/1.8

y=2.13
