Answer:
f(-3)=-5
The problem:
(-3,-5) on the graph of f implies which of the choices:
A) f(-3)=-5
B) f(-3,-5)=-8
C) f(-5)=-3
D) f(-5,-3)=-2
Step-by-step explanation:
If the name of the function is f and (-3,-5) is on the graph of f, then you can conclude the value y=-5 corresponds to x=-3.
In other words, the value f(x) is -5 when x=-3.
f(x)=-5 when x=-3 just means f(-3)=-5.
In short, (a,b) on f means that f(a)=b.
Answer:
c. 9/12
Step by step explanation.
Given: sin = 9/15
and,
thus, find adj. side
by using Pythagoras theorem
then,
let adj. side be a^
thus,
adj. side is 12
then,
tan of the angle = 9/12
Answer:
-12
Step-by-step explanation:
First do multiplication.
And then, do the rest of the equation from left to right.
Answer that question to get:
-12
Hope this helped! :)
Here is the solution based on the given situation above.
Given: 450 kg = weight limit of the elevator
750 kg = current weight of the group of passengers
? = number of passengers who weigh 70 kgs that need to get off the elevator
So to get the answer, first we need to deduct 450kg from 750 kgs to get the excess weight. So 750 - 450 is 300kgs. Next, we divide 300 by 70kgs to get the number of passengers that need to get off so 300/70 is 4.3. Therefore, there should be 4 passengers who weigh 70 kilograms that need to get off the elevator.
