Answer: 57 ft²
Step-by-step explanation:
Find the areas of the two individual rectangles and then add that up to find the area of the figure:
Rectangle A: Rectangle B:
= Length * Width = 11.5 * 3
= 7.5 * 3 = 34.5ft²
= 22.5 ft²
Area of figure:
= 22.5 + 34.5
= 57 ft²
Answer:
(19 , -14)
Step-by-step explanation:
Find the distance in between each x & y for a coordinate.
Let: (x₁ , y₁) = (-1 , 2)
Let: (x₂ , y₂) = (9 , -6)
From x₁ ⇒ x₂: 9 - (-1) = 10
From y₁ ⇒ y₂: -6 - 2 = -8 = 8*
*Remember that distance cannot be negative, but for the sake of this question, we will leave it as -8.
The distance between the x points are in intervals of 10. The distance between the y points are in intervals of 8. Add 10 & subtract 8 to their respective numbers to get endpoint 2:
(9 (+ 10) , -6 (- 8)) = (19 , -14)
Endpoint 2 = (19 , -14)

Answer:
3.9 units
Step-by-step explanation:
We are given that,
Time taken by each swing = 2.2 seconds
The pendulum formula is given by,
, where T is the time taken and L is the length of the swing.
So, we have,
![2.2= 2\pi \sqrt{\frac{L}{32}}](https://tex.z-dn.net/?f=2.2%3D%202%5Cpi%20%5Csqrt%7B%5Cfrac%7BL%7D%7B32%7D%7D)
i.e. ![\frac{2.2}{2\pi}=\sqrt{\frac{L}{32}}](https://tex.z-dn.net/?f=%5Cfrac%7B2.2%7D%7B2%5Cpi%7D%3D%5Csqrt%7B%5Cfrac%7BL%7D%7B32%7D%7D)
i.e. ![(\frac{2.2}{2\pi})^{2}=\frac{L}{32}](https://tex.z-dn.net/?f=%28%5Cfrac%7B2.2%7D%7B2%5Cpi%7D%29%5E%7B2%7D%3D%5Cfrac%7BL%7D%7B32%7D)
i.e. ![L=32\times (\frac{2.2}{2\pi})^{2}](https://tex.z-dn.net/?f=L%3D32%5Ctimes%20%28%5Cfrac%7B2.2%7D%7B2%5Cpi%7D%29%5E%7B2%7D)
i.e. ![L=32\times \frac{4.84}{4 \pi^2}](https://tex.z-dn.net/?f=L%3D32%5Ctimes%20%5Cfrac%7B4.84%7D%7B4%20%5Cpi%5E2%7D)
i.e. ![L=32\times \frac{1.21}{\pi^2}](https://tex.z-dn.net/?f=L%3D32%5Ctimes%20%5Cfrac%7B1.21%7D%7B%5Cpi%5E2%7D)
i.e. ![L=\frac{38.72}{9.87}](https://tex.z-dn.net/?f=L%3D%5Cfrac%7B38.72%7D%7B9.87%7D)
i.e. L = 3.923 units
So, rounded to tenths, the length of the swing is 3.9 units.
Answer:
New balance = -151.89 + 4.5x
(where x is the value of the smaller deposit)
Step-by-step explanation:
The inicial balance was -126.89.
Then, it were made two deposits, one with the value of x, and one that is 3 1/2 times the other, that is, 3.5x.
Then, the customer made a withdraw of $25.
So, The new balance can be calculated as:
New balance = inicial balance + x + 3.5x - 25
New balance = -126.89 + 4.5x - 25
New balance = -151.89 + 4.5x
