Answer:
118.3 m²
Step-by-step explanation:
The area (A) of a triangle is
A =
bh ( b is the base and h the perpendicular height )
Note the legs 13 and 18.2 are at right angles to each other, hence
A = 0.5 × 13 × 18.2 = 118.3
Answer:
Answer to all three points is NO.
Step-by-step explanation:
Case 1:
![\lim_{x \to \>>1} f(x)= 1](https://tex.z-dn.net/?f=%5Clim_%7Bx%20%5Cto%20%5C%3E%3E1%7D%20f%28x%29%3D%201)
Answer : NO, It is important to note that the even if function is not defined, the limit of function can exist and it doesn't mean that f(x) must necessarily be defined at x = 1
Case 2:
Answer : No, because it could be a piece wise function even if f is defined, where f(1) might have different values while approaching from right and left side of limits.
Case 3:
Answer: No, value of f(1) can not be concluded
In this question, we are given a matrix, and we have to perform the given operation.
The matrix is:
![\left[\begin{array}{ccc}6&-1&|5\\1&-5&|0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D6%26-1%26%7C5%5C%5C1%26-5%26%7C0%5Cend%7Barray%7D%5Cright%5D)
The following operation is given:
![R_1 \rightarrow -6R_2 + R_1](https://tex.z-dn.net/?f=R_1%20%5Crightarrow%20-6R_2%20%2B%20R_1)
In which
is the element at the first line and
is the element at the second line.
Updating the first line:
![R_{1,1} = -6*1 + 6 = 0](https://tex.z-dn.net/?f=R_%7B1%2C1%7D%20%3D%20-6%2A1%20%2B%206%20%3D%200)
![R_{1,2} = -6*-5 - 1 = 30 - 1 = 29](https://tex.z-dn.net/?f=R_%7B1%2C2%7D%20%3D%20-6%2A-5%20-%201%20%3D%2030%20-%201%20%3D%2029)
![R_{1,3} = -6*0 + 5 = 5](https://tex.z-dn.net/?f=R_%7B1%2C3%7D%20%3D%20-6%2A0%20%2B%205%20%3D%205)
Thus, the filled matrix will be given by:
![\left[\begin{array}{ccc}0&29&|5\\1&-5&|0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0%2629%26%7C5%5C%5C1%26-5%26%7C0%5Cend%7Barray%7D%5Cright%5D)

Answer: <u>5 erasers</u>
Step-by-step explanation: $5x5=25 so, 31-25=6 which means he bought 1 magazine so 31-6=25 and 25/$5 = 5.
So he/she bought 5 erasers and 1 magazine.
