Answer:
137.5 cm ^2
Step-by-step explanation:
9*11 = 99
(7*11)/2=38.5
99+38.5=137.5

Answer:
The interval notation is;
![(-\infty,4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C4%5D)
Step-by-step explanation:
The solution set of the inequality represented on the number line is
![x\le4](https://tex.z-dn.net/?f=x%5Cle4)
The boundary 4 is inclusive in the solution set, so we use square bracket "[ ]" to show inclusion and open bracket "()" to show that, that part of the interval in not bounded.
In interval notation, we can write this as;
![(-\infty,4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C4%5D)
Repeated
Answer: Vector= ![\frac{48i}{\sqrt{113} } + \frac{42j}{\sqrt{113} }](https://tex.z-dn.net/?f=%5Cfrac%7B48i%7D%7B%5Csqrt%7B113%7D%20%7D%20%2B%20%5Cfrac%7B42j%7D%7B%5Csqrt%7B113%7D%20%7D)
Step-by-step explanation:
A vector w of length 6 in the direction of v= 8i + 7j is given by
Vector= Length x Vector/Magnitude of vector
Here, Length= 6
Vector= 8i + 7j
Magnitude of vector= ![\sqrt{(8)^2+(7)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%288%29%5E2%2B%287%29%5E2%7D)
Magnitude of vector= ![\sqrt{113\\](https://tex.z-dn.net/?f=%5Csqrt%7B113%5C%5C)
So, Vector= 6 x ![\frac{8i + 7j}{\sqrt{113} }](https://tex.z-dn.net/?f=%5Cfrac%7B8i%20%2B%207j%7D%7B%5Csqrt%7B113%7D%20%7D)
Vector= ![\frac{48i}{\sqrt{113} } + \frac{42j}{\sqrt{113} }](https://tex.z-dn.net/?f=%5Cfrac%7B48i%7D%7B%5Csqrt%7B113%7D%20%7D%20%2B%20%5Cfrac%7B42j%7D%7B%5Csqrt%7B113%7D%20%7D)
