Answer:
19.
Step-by-step explanation:
PEMDAS.
3^2=9
5 x 2 + 9
10 + 9 = 19
Complementary angles = 90
x+y =90
y=x+24
substitute this in to the equation
x+x+24=90
2x+24=90
subtract 24 from each side
2x = 66
divide by 2
x=33
y = 33+24
y=57
Answer: 33, 57
Answer:
Please find attached the graph of the following function;

Step-by-step explanation:
We note that the function is linear from x = 2 to just before x = 0
The linear relationship of the function f(x) with x changes just before x = 0
At x = 0, the value of f(x) is indicated as 1
From just after x = 0, the function is a straight horizontal line y = 3
The function also changes value immediately after x = 0 to the line y = 3
The areas where the function is defined are shown in continuous lines
Answer:
21.06
Step-by-step explanation:
4.06 increased by 17
4.06 + 17
21.06
Answer:
72.4 seconds
Step-by-step explanation:
We are given that,
Time taken by each person in the team = 18.1 seconds
Number of members in the team = 4
It is required to find the total time taken by the team to finish the race.
Thus, the time taken taken = 4 × 18.1 = 72.4 seconds
Hence. the team finished the race in 72.4 seconds.
