The estimation for 10.2 is 10, if it is rounded to the nearest whole number.
Yes it is the same as having no slope.
Answer:
92
Step-by-step explanation:
Given
2n + t² ← substitute n = - 4 and t = - 10 into the expression
= 2(- 4) + (- 10)² = - 8 + 100 = 92
Answer:
|x - 27.6| = 5.3
Step-by-step explanation:
We are told that the average time for athletes on the Central High School track team to run 200 meters is 27.6 seconds.
Also, that the slowest and fastest recorded times varied from the average by 5.3 seconds.
Thus means that the the slowest time was (27.6 + 5.3) seconds and fastest time was (27.6 - 5.3) seconds.
Thus,if the slowest or fastest time is denoted by "x", the absolute value equation is;
|x - 27.6| = 5.3
Answer:
‹A = 141°
‹B = 28°
‹C = 11°
*These angles are rounded to the nearest whole*
Step-by-step explanation:
Because you are only given sides you can find an individual angle measures with the inverse law of cosines.
Remember the side opposite of the angle corresponds to that angle.
a² = b² + c² - 2bc cos(A) →
A = cos⁻¹ (a² - b² - c² / -2bc)
b² = a² + c² - 2ac cos(B) →
B = cos⁻¹ (b² - a² - c² / -2ac)
c² = a² + b² - 2ab cos(C) →
C = cos⁻¹ (c² - a² - b² / -2ab)
