; a₁ is the first term, d is the difference between terms, and n is the term
-4, -21, -38, ... ⇒ a₁ = -4, d = -17
= -4 - 17n + 17
= 13 - 17n
= 13 - 1088
= 1075
Answer: 1075
You'll apply the geometric mean formula. The idea is to multiply the two pieces of the hypotenuse: 5*11 = 55
Then apply the square root to get sqrt(55)
The exact answer in terms of radicals or square roots is sqrt(55)
Using a calculator, the approximate answer is sqrt(55) = 7.416198
If your teacher wants you to use a proportion, then one way to do it is to have
11/y = y/5
11*5 = y*y
55 = y^2
y^2 = 55
y = sqrt(55)
y = 7.416198 approximately
Answer:
No, this isn't a right triangle.
Step-by-step explanation:
First of all, the hypotenuse is the longest side (in this case that is 50), so that's what we're working for.
The formula for the Pythagorean theorem is :
14 squared equals 196, and 28 squared equals 784. Add these and you get 980. The square root of 980 is not 50, so we know that this is not a right tryangle.
Answer:
813 N/m²
Step-by-step explanation:
The units of pressure tell you it is found by dividing force by area. Here, we need to convert the units of the given area so we can express the pressure appropriately.
__
pressure = force / area
pressure = (61 N)/(750 cm² × ((1 m)/(100 cm))²) = (61 N)/(0.0750 m²)
pressure ≈ 813 N/m²
Answer: 174ft^2
Area of triangle: (bh)/2
A = (6*4)/2
A = 24/2
A = 12ft^2
Area of rectangle: LW
A = 18(9)
A = 162ft^2
Add area of rectangle and triangle together
A = 162ft^2 + 12ft^2
A= 174ft^2
