Negative Square roots (imaginary numbers)

Answers

Answer 1

Answer:

As shown earlier, a negative square root is one of two square roots of a positive number. For the number 25, its negative square root is -5 because (-5)^2 = 25. We can solve certain equations by finding the square root of a number. Let's consider the equation of x^2 = 121.

John wants to measure the height of a tree. His eye level is 6 feet from the ground. He walks exactly 100 ft from the base of
the tree and looks up. The angle from the Johns eye level to the top of the tree is 33º. How tall is the tree?

Answers

Answer:

70.9 feets

Step-by-step explanation:

From trigonometry:

tan θ = opposite /Adjacent

Opposite = tree height, y

Adjacent = vertical distance between eyelevel and tree

tan 33º = y/100

y = 100 * tan 33º

y = 100 * 0.6494075

y = 64.9 feets

Distance between John's eye level and the ground = 6 feets

Total tree height = 6 + 64.9 = 70.9 feets

Step-by-step explanation:

The slope is 4/5

Answer:

[tex]\frac{4}{5}[/tex]

Step-by-step explanation:

slope = [tex]\frac{rise}{run}[/tex]

rise = y axis

run = x axis

to find the slope, go to (0, -1) and move up until you reach the y-axis where (5,3) is (it would be at number 3 on the y axis), then go right until you reach where (5,3) is (it would be number 5 on the x axis)

Graph f(x)=|x−6|−4.

Use the ray tool to graph the function.

Answers

Answer:

Imagine the function y = absolute value(x). It looks like the English letter "V". The bottom of our V (i.e f(x) touches the x-axis when x = 6, so the "V" graph has been translated 6 units to the right of the origin. But  when x = 6 the value of f(x) is 0-4 = -4 so the tip of the V is located 4 units below the x axis. Summary:  g(x) looks like the absolute value function but  is translated 6 units to the right of the origin and 4 units down

Step-by-step explanation:

The vertex of the absolute function is at (6, -4). Then the graph of the function is attached below.

What is an absolute function?

The absolute function is also known as the mode function. The value of the absolute function is always positive.

If the vertex of the absolute function is at (h, k). Then the absolute function is given as

f(x) = |x - h| + k

The equation is given below.

f(x) = |x - 6| - 4

From the equation, the vertex of the absolute function is at (6, -4). Then the graph of the function is attached below.

More about the absolute function link is given below.

10. The sum of a certain number and a second number is -42. The first
number minus the second number is 52. Find the numbers.
56​

Answers

Answer:

the first number and the second number is 5 and -47 respectively

Step-by-step explanation:

Let us assume the first number be x

And, the second number be y

According to the question

x + y = -42

x - y = 52

x = 52 + y

Now put the value of x in the first equation  i.e.

x + y = -42

52 + y + y = -42

2y = -42 - 52

2y = -94

y = -47

And, x is

x + y = -42

x -47 = -42

x = 5

Hence, the first number and the second number is 5 and -47 respectively

Two roller coasters are vying for the title of the steepest drop the first ride has a hill that drops 140 feet in a 40 foot run the second ride drops 105 feet in a 30 foot run which statement is true

Answers

Answer:

They have the same slope

Step-by-step explanation:

Given

Coaster 1:

[tex]Drops = 140ft[/tex]

[tex]Run = 40ft[/tex]

Coaster 2:

[tex]Drops = 105ft[/tex]

[tex]Run = 30ft[/tex]

First, we calculate the slope (m) of both coasters

[tex]m = \frac{Rise}{Run}[/tex]

[tex]m = \frac{Drops}{Run}[/tex]

For coaster 1:

[tex]m = \frac{140ft}{40ft}[/tex]

[tex]m = \frac{140}{40}[/tex]

[tex]m = 3.5[/tex]

For coaster 1:

[tex]m = \frac{105ft}{30ft}[/tex]

[tex]m = \frac{105}{30}[/tex]

[tex]m = 3.5[/tex]

[tex]m = m=>3.5 = 3.5[/tex]

By comparison, they have the same slope

Problem 7

Answer:   $70 per month

This is because he needs $280 in total for holiday shopping (200+80 = 280). Divide this over 4 to get 280/4 = 70.

=================================================

Problem 8

Net Monthly Income = $541.64Transportation Insurance = $110Gas and Repairs = $65Cell Phone = $30Saving: Holiday Expense = $135e-Reader = $80Total Expenses = $420Balance Remaining (Discretionary Income) = $121.64

There's not much to explain other than we're just gathering all of the values we found earlier. The total expenses has us summing pretty much everything but the monthly income. Keep in mind that the expenses for next month won't include one time purchases such as the e-Reader.

=================================================

Problem 9

This was already asked in problem 6

=================================================

Problem 10

Answer: $300 per month

Explanation:

He needs 300+600 = 900 dollars per semester. Keep in mind that this is just for books and personal needs, and we're excluding tuition or other costs.

Assume he attends a 4 year university. This means there are 4*2 = 8 semesters. Therefore, he needs 8*900 = 7200 dollars overall. Divide this over 24 months (equivalent to 2 years) and we get 7200/24 = 300

He needs to save $300 per month to put toward college expenses.

If we go back to problem 3, this means his discretionary income of $336.64 will drop to 336.64-300 = 36.64 dollars assuming he puts the 300 in the college account each month. Keep in mind that I'm not accounting for compound interest, CDs, etc to help grow the money already in the account.

Options are: A) sin0= 119/120, B) sin0= 120/119, C) sin0= 119/169, and D) sin0= 120/169

Answers

Answer:

119/169

Step-by-step explanation:

Answer:

sin0 = 119/169

Step-by-step explanation:

In trigonometry, the formula for sine is opposite/hypotenuse

To find the opposite, you find the angle and look what is right across from it. In this case 119 is right across from the angle.

And of course, our hypotenuse is 169.

Therefore, your answer is

Sin0 = 119/169
