Answer:
Her answer is wrong because she the object cannot hit the ground at negative seconds. She could’ve have used other methods because she used the quadratic formula. The advantages is that it works for every situation. The disadvantages is that it takes longer. She should’ve used a different method.
Step-by-step explanation:
Since all three sides are different lengths and angles, that triangle would be considered an Isosceles triangle.
Answer:
119°
Step-by-step explanation:
if sum of two angles=180,then they are supplementary.
61+x=180
x=180-61=119
2 and 14/15
Because the first step of subtraction is common denominators
I guess that u = μ & that a=σ. If so:
μ =100 & that σ =20 & x=20
Z score = (x-μ) / σ ==> Z score = (90-100)/20 ==> Z = - 0.5
