Answer:

Step-by-step explanation:

1. X/2 when x = 1/2

Putting value of x in the equation

1/2 /2 = 0.25

2. 2x2 - 8 when x = 3

2(3)2 - 8

= 2(9) - 8

= 18 - 8 = 10

3. 4(x - 7)3 + 5 when x = 9

4 (x3 - 21x2 + 147x - 343) + 5

Putting value of x

4((9)3 - 21(9)2 + 147(9) - 343) + 5

4(729 - 1701 + 1323 - 343) + 5

4(8) + 5

= 32 + 5 = 37

Answer 2

Answer:

1. 0.25

2. 208

3. 517

Step-by-step explanation:

Number 1.

0.5/2

number 2.

2(3)^3-8

6^3 - 8

216-8

= 208

Number 3.

Solve the equations. Make conclusion. 3|x+12|=6

*Please put down the steps also.*

Answers

3 | x+12 |=6
Start by distributing 3 to both x and 12
You get 3x+36=6
Subtract 36 from both sides
You then get 3x=-30
Divide 3 from both sides getting
x= -10

Samuel used clay to make a diorama of the pyramids in Ancient Egypt. He made two triangular pyramids and three rectangular pyramids. How much clay did he use to create all the pyramids

Answers

Answer:

124.16 cubic meter of clay will be used to create all the pyramids

Solution

The total clay used is equal to the sum of volumes of two triangular and three rectangular pyramids.

For Rectangular Pyramid,

Volume of three rectangular pyramids

3 * BH/3 = BH

Substituting the given values in above equation, we get -

15.5 * 5 = 77.5 cubic centimeter

For triangular Pyramid,

Volume of two triangular pyramids

2 * BH/3

2* 10 * 7/ 3

46.67 cubic centimeter

Total clay used = Volume of 3 rectangular pyramid + volume of 2 triangular pyramid = 77.7 + 46.67 = 124.16 Cubic centimeter

a wildlife manager determines that the function y=200x1.07* represents the deer population at a state park x years after the population is first counted. what is the population after 12 years? what is the initial population? what is the percentage rate? complete the table below.

Answers

Answer:

Table:

4, 262

8,344

12, 450

Population after 12 years is 450 deer

Initial population is 200 deer.

Step-by-step explanation:

You take the x in the table and plug it in as an exponent so you will need a calculator or multiple the 1.07 by that many times so 1.07 12 times multipled by itself. and the initial is 0 years so anything to the exponent of 0 is 1 so that show i got 200 for the x=0

Plants need three things for photosynthesis to occur: water, carbon dioxide and sunlight. How do those things enter a plant? Water, along with important minerals, enters a plant from the soil where the plant's roots act like straws "drinking" it up. Carbon dioxide enters a plant from the atmosphere, and it comes in through the leaves. More specifically, carbon dioxide enters a plant through tiny pores or openings on leaves called stomata. Sunlight, obviously, comes from the sun. But how does it enter the plant to be converted into chemical energy that the plant can use? Well, green plants are green because of a pigment called chlorophyll. That pigment inside of plant cells absorbs the sun's energy, making it possible for photosynthesis to occur.Based on the passage, if human cells had a lot of chlorophyll, they would most likelyAnot need to drink water.Bbe green.Cbreathe carbon dioxide.Dhave leaves.
