The terminal side of θ passes through the point (10, 6). What is the exact value of cos θ in simplified form?
Answer:
[tex]\frac{5\sqrt{34}}{34}[/tex]
Step-by-step explanation:
The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = [tex]\sqrt{a^{2} + b^{2} }[/tex].
In the equation you'd write that as r = [tex]\sqrt{10^{2} + 6^{2}[/tex] which can be simplified to [tex]\sqrt{136[/tex].
You end up with [tex]\frac{10}{\sqrt{136} }[/tex] and you simplify this by doing [tex]\frac{10 }{\sqrt{136} } * \frac{\sqrt{136} }{\sqrt{136} }[/tex], ending with the result of [tex]\frac{5\sqrt{34}}{\sqrt{34} }[/tex].

Describe how probability and odds are related.
Answer: The probability that an event will occur is the fraction of times you expect to see that event in many trials. Probabilities always range between 0 and 1. The odds are defined as the probability that the event will occur divided by the probability that the event will not occur.

Anna earns money by walking dogs on Saturdays. Each Saturday she walks 5 dogs for 30 minutes. She charges one
customer $8 because the dog is very large. Each of the other customers pays $6. Which equation could be used to find out
how much money Anna earns each Saturday?
A)
y = 6 + 8
B)
y = 4 x 6 + 8
09
y = 4 * 6-8
D)
y = 5 x 6 + 8
Answer:
y = 4 x 6 + 8
Step-by-step explanation:
the 4 is the amount of dogs that arent big
the is 6 is the amount that she gets for walking the normal sized dogs
the 8 dollars is the amount that she gets for walking the big dog
so you would multiply 4x6 which would give you 24
then add the 8 and you will get 32
so that would mean she gets 32$ every saturday
i apologize if my math is wrong but i am certain this is the correct answer
Irene says the equation 9x+15=3x+15 has no solution because 9x is greater then 3x. is he right yes or no and explain why
Answer:
This equation has one solution, if x = 0
Step-by-step explanation:
Because, you subtract 15 from both sides so: 9x + 15 - 15 = 3x + 15 - 15 which equals: 9x = 3x. if x = 0 this equation is true.
Answer:
X=0
Step-by-step explanation:
If we subtract 15 from both sides, then we can see 9x=3x. If x was 0, then the equation would be 9x0=3x0. Since 0 times anything equals 0, this equation would be true resulting in 0=0.

Answer:
vnfcjvfn dcjxfhhnvn vn
Step-by-step explanation:
Answer:
the value of 7x-y is -14.
Step-by-step explanation:
When x=2 and y=4,
To find the value of 7x - y when x =2, y = 4, this means when ever you see x, put 2 in replacement, y, put 4 respectively.
7x - y = 7(2 - 4)
14 - 28
= -14.

Which expression represents the area of the vegetable garden in square yards?
8x2 + 54x + 27
12x2 - 27
8x2 + 60x - 27
12x2 + 48x - 27
Answer:
I think is 12x2 +48x-27 but I'm confused
Answer:
[tex]A=12x^2+48x-27[/tex]
Step-by-step explanation:
Area of a Rectangle
The image shows a rectangular vegetable garden with different crops.
The rectangle has a length of L=2x+9 yards and a width of W=6x-3 yards.
The area of a rectangle is:
A = WL
[tex]A=(2x+9)(6x-3)[/tex]
Operating:
[tex]A=2x(6x)-2x(3)+9(6x)-9(3)[/tex]
[tex]A=12x^2-6x+54x-27[/tex]
Simplifying:
[tex]\boxed{A=12x^2+48x-27}[/tex]
which is the simplified form of the expression 3 (6x + 4) – 2 (1 - 1)
Answer:
18x + 12.
Distribute the properties, then calculate.
18x + 12 - 2 + 2
- 2 + 2 is contradictory and cancels each other out.
18x + 12.
Joey is building a doghouse. He measures the lengths of two sides and the hypotenuse to make sure the boards create a right triangle.
Which of the measurements below could be used to create the right triangle?
5 in, 7 in, 12 in
8 in, 12 in 14 in
5 in, 9 in, 11 in
6 in, 8 in, 10 in
pleasee help mee
Answer: 6in, 8in, 10in
6 squared + 8 squared equals to the radical of 100, which equals to 10 because 10 squared is.. 100
The measurements that can be used to build a right-angled triangle are
[tex]6 in, 8 in, 10 in[/tex]
The measurements that can be used to build a right-angled triangle must form a Pythagorean triple. A Pythagorean triple is a set of three numbers [tex]\{x,y,z\}[/tex] that satisfy the Pythagorean relationship
[tex]x^2+y^2=z^2[/tex]
The measurements [tex]\{5 in, 7 in, 12 in\}[/tex] do not form a triple since
[tex]5^2+7^2=74\ne12^2[/tex]
The measurements [tex]\{8 in, 12 in, 14 in\}[/tex] do not form a triple since
[tex]8^2+12^2=208\ne14^2[/tex]
The measurements [tex]\{5 in, 9 in, 11 in\}[/tex] do not form a triple since
[tex]5^2+9^2=106\ne11^2[/tex]
The measurements [tex]\{6 in, 8 in, 10 in\}[/tex] form a triple since
[tex]6^2+8^2=100=10^2[/tex]
So, the last set of measurements [tex]6 in, 8 in, 10 in[/tex] can be used to build a right-angled triangle

A school receive a shipment of four boxes of paper in the school wants to split the paper equally among its three printers how much paper should go into each printer?
Answer:
[tex]\dfrac{4}{3}[/tex]
Step-by-step explanation:
Number of boxes of paper = 4
Number of printer = 3
We have to find the number of pages in each printer.
Let the number of pages in each box be 1.
Total number of pages in 4 boxes = 4
3 printer will have pages = 4
1 Printer will have pages = [tex]\dfrac{4}{3}[/tex]
Hence, pages each printer will have is equal to [tex]\dfrac{4}{3}[/tex].
