Answer:
-7/8
Step-by-step explanation:
Quadratic formula is ax^2 + bx + c
In this case, x = -b/2a, which is -7/(2(4)) = -7/8
Answer:
he is will have to get 5
Step-by-step explanation:
53/10=5.3
you cant have ".3" box so you have to round it off
Remember that tif the legs of a right tirsnalge are a and b and they hypoonuse is c then
a²+b²=c²
so
we also know that the area of a triangle is 1/2bh
we are given that area=60 and base=8
so
60=1/2 times 8 times height
60=4 times height
divide both sides by 4
15=height
so the legs are 15 and 8
a=15
b=8
15²+8²=c²
225+64=c²
289=c²
sqrt both sides
17=c
the hypoonuse is 17ft
it's asking you to construct a right triangle. The answer is -2,-3 because a right triangle would be formed at that point.
Answer:
10, 20, 15
Step-by-step explanation:
10 is the lowest so that leaves the mean and range well the range is the highest value minus the lowest and the range is 10 so 20-10=10
so we now have 10 and 20 so then what number divided by three as in three darts equals 15 I go down the list and I get 45/3 and it equals 15
