Answer: What is the distance formula is that it's the formula used in Mathematics such as Pre-Algebra, Algebra 1, Geometry, Algebra 2, Trigonometry, and Pre-Calculus, also Calculus to help you find the distance between 2 points in a coordinate plane or the length of a segment. How you do the distance formula is you subtract the 2nd x coordinate by the 1st one, next you add the 2nd y coordinate to the 1st one, then the answer you get you evaluate them using the exponent of 2, lastly you add that answer and square root the answer you get to the approximate or closest decimal or whole number.
Answer: y=5x+7
Step-by-step explanation:
Since we are given the slope, all we have to do is plug in the given point and solve for the y-intercept.
-3=5(-2)+b [multiply]
-3=-10+b [add both sides by 10]
b=7
Now, we know the equation is y=5x+7.
Answer:
<u>Given</u>
- ΔTQR is right
- QS is altitude
- ΔRSQ and ΔTSQ also right
- m∠TQS = 42°, RS = 26 cm
∠RQS and ∠TQS are complementary with ∠TQS, so are 48°
a)
- ∠QRS is the another one with 42°
b)
<u>Find QS first</u>
- 26/QS = tan 48°
- QS = 26 / tan 48° = 23.4
<u>Find QT next</u>
- QS/QT = cos 42°
- QT = QS / cos 42° = 23.4 / cos 42° = 31.5 (rounded)
