Answer: 2000
Step-by-step explanation:
At a football game, 65% of people that will attend are supporting the home team, while 35% are supporting the visiting team. 1300 people that attended supported the home team.
To get the total number of people that attended the game, we have to find the number of away supporters as well.
Let the number of people that attended the game be y.
Therefore 65% of y = 1300
65/100 × y = 1300
0.65 × y = 1300
0.65y = 1300
Divide both side by 0.65
0.65y/0.65 = 1300/0.65
y = 2000
The total number of people attending the game is 2000.
The way that I memorised how to do sin, cos, and tan is by the following: SOH, CAH, TOA
SOH = Sin is OPPOSITE / HYPOTENUSE
CAH = Cos is ADJACENT / HYPOTENUSE
TOA = Tan is OPPOSITE / ADJACENT
For example if we were to solve question 5
Sin T = 6 root 2 / 19
Cos T = 17 / 19
Tan T = 6 root 2 / 17
Repeat the steps for question 6
For the rest of the questions (7,8,9) you have to take the information given and figure out if you should us Sin, cos, or Tan. then plug the numbers in the calculator and while doing sin ^ -1, cos ^ -1, tan ^ -1
for example on question 7, to find the angle x they have given you the hypotenuse and the adjacent side so
cos x = 9 / 18
to find x plug: cos^-1 (9/18) in the calculator
Answer:
-7x≥-21
Solution:
-7x ≥ -21
÷-7 ÷-7
flip the sign when we divide by a negative number
x ≤ 3
≥ and ≤ mean closed dot
The function will exist on all real numbers. Hence the domain of the exponential function given is all real numbers
<h3>Domain of a function</h3>
The domain are independent values of an expression for which it exist. The standard exponential equation is expressed as y = ab^x
Given the exponential function as shown:
y = 5(3)^x
The function will exist on all real numbers. Hence the domain of the exponential function given is all real numbers
