Given the function:
f(x)=-x^2-5x+50
the zeros of the function will be obtained by factorizing the expression.
f(x)=-x^2-5x+50
f(x)=-(x^2+5x-50)
f(x)=-(x-5)(x+10)
the zeros are:
x=-10
x=5
hence taking the positive value for distance, we take x=5.
This represents the horizontal distance the diver jumped. Thus the correct answer is:
<span>x = 5; the diver hits the water 5 feet away horizontally from the board
</span>
I believe the answer is x+20.
Answer:
The triangles are not congruent
Step-by-step explanation:
Triangle ABC is congruent to triangle DEF
Triangle ABC is congruent to triangle FED
Two trianges ABC and DEF are given on a coordinate plane
3(2a+1)-a
6a+1-a→→ 6a-a equals 5a
5a+3
the number in the first box is 5 and the second box 3
Answer:
No.
Step-by-step explanation:
Your keyword here is "given." If we calculate the probability of an event, GIVEN that one event occurs, too, then we have dependent events, because the outcome of one event relies on the other. For this scenario, you have the probability of absence on any day of the week is 0.08, but then they say "well, but if it's Friday, that probability actually goes up quite a bit." This tells you that your events aren't independent because the day being Friday increases the chances of a student being absent from the baseline 0.08 probability.
