Answer:
other leg is 8.94
Step-by-step explanation:
Pythagorean Theorem is a² + b² = c²
a and b are legs
c is the hypotenuse
8² + b² = 12²
64 + b² = 144
-64 -64
b² = 80
√b² = √80
b ≈ 8.94

Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c
using substitution put the numbers into the formula
</span>(-b±√(b^(2)-4ac))/(a^(2))
(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify
(1±√(1+56))/4
1±√(57)/4 is your answer
Answer:
78 mg
Step-by-step explanation:
370 mg - 110 mg = 260 mg (amount decayed in the 8 total years)
260 mg ÷ 8 years = 32.5 mg decayed per year
32.5 × 9 years (years between 2008 and 2017) = 292.5 mg
370 mg - 292.5 mg = 77.5 mg, rounded to 78 mg
Answer:
Step-by-step explanation:
-3.5 means -(3 + 
)
In other words, -3.5 = 
When we draw two numbers 
and on a number line, comes first from left to right.
We know that all the numbers on a number line from left to right are in increasing order.
Therefore, is smaller than .
