Find the length of the third side. If necessary, round to the nearest tenth
Pythagorean Theorem (Rounding)

Answers

By using the Pythagorean Theorem, we will see that the length of the missing side is 4 units.

How to find the length of the third side?

We need to remember the Pythagorean Theorem, the sum of the squares of the cathetus is equal to the square of the hypotenuse.

In this case, the cathetus are x and 3, and the hypotenuse is 5, then we have:

x^2 + 3^2 = 5^2

x^2 = 25 - 9 = 16

x = √16 = 4

So the length of the missing side is 4 units.

A pebble falls off the top of a cliff. Its final velocity is 58.8m/s. How long does it take to reach the ground? Show
your work.

Answers

Answer: 5.7s

Step-by-step explanation:

We are explicitly given the final velocity of 58.8m/s, and implicitly given the acceleration of 9.8m/s^2 due to gravity. We are also implicitly given the initial velocity of the pebble. The pebble was not thrown off the cliff, it simply fell off the cliff. Therefore the initial velocity is 0m/s. Using the first kinematic equation, you get:

[tex]v_f=v_i+at[/tex]

[tex]58.8=0+(9.8)t[/tex]

[tex]58.8=9.8t[/tex]

what is amount ?

The word "amount" in mathematics refers to something's quantity or value in general. Depending on the context, it may refer to a wide range of concepts. "Amount" can, among other things, refer to the total value of a group of numbers, the total price of an acquisition, the total number of items in a collection, or the total amount of money in an account. The word "amount" is frequently used in financial situations to refer particularly to a sum of money, either as a total value or as a specific payment or transaction.

given

After 1 year, the amount Linda will have is:

200 * 1.05 = $210

After 2 years, the amount Linda will have is:

210 * 1.05 = $220.50

=> 200 + 60

=> 260 cm²

Answer:

Area of the triangle

Write the equation for each translation of the graph of y=|x+2|. a) one unit up b) one unit down c) one unit to the left d) one unit to the right

Answers

[tex]y = |x + 2| [/tex]

____________________________________________

a ) one unit up

As you know all kind of vertical transfers are along the y-axis thus :

[tex]y = |x + 2| + 1[/tex]

____________________________________________

b ) one unit down

[tex]y = | x + 2| - 1[/tex]

_____________________________________________

c ) one unit to the left

Working with the operation along the x-axis are all opposite so when the question say transfer the graph on unit to left it means to decrease all x values by one unit and we have to do the inverse work with mean to increase all the x values by one unit :

[tex]y = |(x +1 ) + 2| [/tex]

[tex]y = |x + 3| [/tex]

_____________________________________________

d ) one unit to the right

[tex]y = |(x - 1) + 2| [/tex]

The height of a poplar tree in feet at age t years can be modeled by the function h(t)=6+3ln(t+1) . use the model to predict the number of years when the height will exceed 18 feet.

Answers

The function h(t)=6+3ln(t+1) is a logarithmic function

The height of the tree will exceed 18 feet after 53.6 years

How to determine the number of years?

The function is given as:

h(t)=6+3ln(t+1)

When the height is 18 feet, we have:

6+3ln(t+1) = 18

Subtract 6 from both sides

3ln(t+1) = 12

Divide both sides by 3

ln(t+1) = 4

Take the exponent of both sides

t + 1 = e^4

Evaluate the exponent

t + 1 = 54.6

Subtract 1 from both sides

t = 53.6

This means that the height of the tree will exceed 18 feet after 53.6 years

A bale of hay in the shape of a rectangular prism has a length of 4 feet, a width of 2 feet, and a height of 2 feet. A cylindrical bale of hay has a diameter of 7 feet and a height of 6 feet. How many rectangular bales contain the same amount of hay as one cylindrical bale?

Answers

Answer:

14.424375 cubed feet (can round)

Sorry if this answer is not correct, if it is or is not, please tell me in the comments!

Step-by-step explanation:

First, find the volume of the rectangular prism which is 4 x 2 x 2 = 16 cubed feet.

Next, find the volume of the cylinder, and use this formula:

πrr (area of one circle) x the height

The r = the radius, but we only have the diameter. We need to divide the diameter by 2 to find the radius. (7 divided by 2 = 3.5 feet)

Now, we can plug all of the numbers in the previous formula:

π(3.5)(3.5) x the height (6 feet) = 230. 79 cubed feet

For the final step, we need to do 230. 79 divided by 16 to find how many rectangular prisms can fit in the cylinder.

So, the answer is 14.424375 cubed feet. (Add the label of "squared feet" and round the answer if you like!)

help! p(x) = 4x^4 - 10x^3 + 8x - 1
x = 8

Answers

Answer:

p(8) = 11,327

Step-by-step explanation:

Hey there!

In order to find the answer, all we need to do is subtitute the x values for 8

After substituting, the equation will look like this:

[tex]p(8)=4(8)^4-10(8)^3+8(8)-1[/tex]

Now we simplify

8 to the power of four is 4096 and when you multiply that by 4, you get 16384

8 to the power of 3 is 512 and when you multiply that by -10, you get -5120

8 times 8 is 64

And then there is -1

Now all we have to do is combine all the answers together for one final answer

16384-5120+64-1 is equal to 11327

So the output of this function when you input 8 is 11,327

Laura’s birthday party has three different colored tables: pink, purple, and green. The pink table has 8 seats. The purple table has 10 seats, and the green table has 8 seats. Laura will assign seats as her friends arrive at her party. What is the probability that the first guest at the party will be placed at the pink table?

Answers

Hello! to find probability, first we need to add the amount of seats together which will give us the total.

8+10+8=26

if there is 26 seats and 8 of them are pink, then the probability of laura’s friend getting a pink seat is 8/26, or 4/13 simplified.

Answers

hello!

In order to solve this inequality, we should divide both sides by 9:-

[tex]\sf{9x < 72}[/tex]

Why 9? Because x is multiplied by 9, and we need to isolate x in order to find its value.

[tex]\sf{x < 8}[/tex]

Hence, that's the solution to the inequality.

It also means that the numbers less than 8 will satisfy the given inequality (make the inequality true)
