Remember SOH CAH TOA
we want the angle between the ground and the hypotenuse
which gives us
or 45.08 degrees

Step-by-step explanation:
5 - (-9) = (-4)
Answer:
irrational
Step-by-step explanation:
what are rational numbers ?
every number that can be expressed as a/b, with a and b being integer numbers, and b different to 0.
the square root of any number that is not a squared rational number is then an irrational number.
I am not sure, if the expression here is
sqrt(13) + 4
or
sqrt(13 + 4), which would then be sqrt(17).
but in both cases we are creating the square root of a not- squared rational number.
neither 13 nor 17 are the result of a multiplication of a rational number with itself.
in fact, 13 and 17 are prime numbers with no other factors than either 1 or themselves.
so, both, sqrt(13) and sqrt(17) are irrational numbers.
adding or subtracting rational numbers to irrational numbers result again in irrational numbers.
Answer:
6. <u> (2x - 1) </u>
(3x + 2)
8. <u> y - 3 </u>
y² - 3y + 9
Step-by-step explanation:
6. <u> 2x² + 9x - 5</u>
3x² + 17x + 10
= <u>(2x - 1) (x + 5)</u>
3x² + 17x + 10
= <u>(2x - 1) (x + 5)</u>
(3x + 2) (x + 5)
= <u> (2x - 1) </u>
(3x + 2)
8. <u>y² - 9 </u>
y³ + 27
= <u> (y + 3) (y - 3)</u>
y³ + 27
= <u> (y + 3) (y - 3) </u>
(y+3) (y² - 3y + 9)
= <u> y - 3 </u>
y² - 3y + 9
Answer:
4.2%
Step-by-step explanation:
The horizontal distance, x (Run) = 22 feets
Rise, vertical distance, y = 11 inches
The slope is the ratio of the vertical to the horizontal distance, Rise to Run
Slope = Rise / Run
Converting to the same unit ;
Foot to inches
1 foot = 12 inches
Hence, x = 22 feets = (12 * 22) = 264 inches
Slope = Rise / Run = 11 / 264 = 0.04167
Slope = 0.04167 * 100% = 4.167%
