Answer:
17.1 meters
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean Theorem.

where a and b are the legs and c is the hypotenuse.
6 and 16 are the legs, because they form the right angle. c is the hypotenuse because it is opposite the right angle.

Evaluate the exponents.
6^2= 6*6= 36
16^2= 16*16= 256

Add 36 and 256.

Since c is being squared, take the square root of both sides of the equation. The exponent and square root will cancel and leave c by itself



Round to the nearest tenth. The 8 in the hundredeth place tells us to roung the 0 in the tenth place up to a 1.

c= 17.1 m
The missing length, or the hyptenuse is 17.1 meters.
Answer:
1. 42.95
2. 8.8 meters; -14 meters
3. -53; 780
Step-by-step explanation:
1. subtract 1985 from 2013, you get 28
plug in 28 to the equation and you get 42.95
2. plug in the values of t
-4.9 (2^2) + 1.7 (2) + 25 = 8.8
-4.9 (3^2) + 1.7 (3) + 25 = -14
3. plug in your values again
5^3 - 6 (5^2) - 8 (5) + 12 = -53
12^3 - 6 (12^2) - 8 (12) + 12 = 780
Answer:
- x³+3x²-6
Step-by-step explanation:
a - b means
b-a
x²-6-( x³ - 2x²)
Distribute the minus sign
x²-6 - x³ + 2x²
Combine like terms
- x³+3x²-6
Answer:
13
Step-by-step explanation:
The computation of the number of people in the chorus are 50 or older is as follows
According to the attached figure
In the age of 50 - 60 , there is 8 people
In the age of 60 - 70 , there is 4 people
In the age of 70 -80, there is 1 people
So, if we do the total that comes
= 8 people + 4 people + 1 people
= 13 people
Hence, the no of people would be 13
