Answer:
The cosine of A is equal to [tex]\frac{3\sqrt{58}}{58}\\[/tex]
Step-by-step explanation:
Cosine is is calculated as adjacent over hypotenuse. The line adjacent to A is 3 in length.
So we can say that the cosine is equal to 3/√58, but need to multiply it by √58 / √58 to ensure we have a non-radical denominator
[tex]A = \frac{3}{\sqrt{58}}\\A = \frac{3\sqrt{58}}{58}\\[/tex]

What is the sum of x^2 - 3x + 7 and 3x^2 + 5x - 9
Answers
Hey there!
The answer to your question is [tex]4x^2+2x-2[/tex]
Given:
[tex]x^2-3x+7[/tex] [tex]and[/tex] [tex]3x^2 +5x-9[/tex]
First, we can start by adding like terms. The following are like terms:
[tex]x^2[/tex] [tex]and[/tex] [tex]3x^2[/tex]
[tex]-3x[/tex] [tex]and[/tex] [tex]5x[/tex]
[tex]7[/tex] [tex]and[/tex] [tex]-9[/tex]
Now, we can add these pairs together, giving us:
[tex]4x^2[/tex]
[tex]2x[/tex]
[tex]-2[/tex]
Now, add all this together, and we get our answer as:
[tex]4x^2 + 2x - 2[/tex]

A farmer has just tilled her 51-yard by 68-yard field. To survey her field, the farmer begins in one corner and walks the length of the field. She then turns and walks the width before crossing diagonally across the field to the original corner. How far does the farmer walk?
Answers
Answer: l +w+ hypotenuse or 204
Step-by-step explanation: so the farmer walks the length then the width of the field then the diagonal which we don't know using pythagorean to find that last side then add the values 51^2+68^2=c^2 and 51+68+85= 204

The sum of two numbers is 51, the difference is 17. Find the numbers.
Answers
Answer:
Sum: 34 + 17 = 51
Difference: 34 - 17 = 17
Step-by-step explanation:
math
Answer:
34, 17
Step-by-step explanation:
We can first get the two equations x + y = 51 and x - y = 17 by calling the first number x and the second one y. Next, we can add y on both sides in the second equation to get that 17 + y = x. Now, since we know that 17 + y is equal to x, we can substitute 17 + y in for x in the first equation. We get that 2y + 17 = 51, and if we subtract by 17 on both sides and get that 2y = 34. This means that y is equal to 17, meaning that x is 34.

Round to the nearest thousand. 6,159
Answers
Answer:
6,000
Step-by-step explanation:
To round to the nearest thousand, you keep the digit in the thousands and round up or down, clearing all other smaller units. You round up when the next largest digit, in this case, the hundreds, is 5 or larger. Meanwhile, you round down when it is 4 or smaller. Here it is 1, so you round down to 6,000. If it was 5 or larger, you would round up to 7,000.
6,000
To round a number we look at the number that is right of the one we are rounding. If the number to the left is 4 or under, you round down. If it's 5 or above, you round up.
