Answer: OPTION B
Step-by-step explanation:
First it is importanty definition, a relation is a function if and only if each input value has one and only one output value.
The input values are the x-values and the output values are the y-values.
Therefore, "y" is the Dependend variable and "x" is the Independent variable.
Knowing the above, you can understand the definition of "Domain" and "Range".
The Domain is defined as the set of all the possible values of "x" or the Independent variable
The Range is defined as the set of all the possible values of "y" or the Dependent variable.
Therefore, you can conclude that the correct answer is the given in the Option B.
Well, we do not know how many fish Rita has, so lets represent that with y. Anyway, it says that catherine has twice as many fish as Rita. So that will be 2y. And Stella has twice as many as catherine, so that will be 2 x 2y. And that will be 4y. So Ruth has y, catherine has 2y and stella has 4y. And the total is 70. So that means that the number of fishes added together will be 70. That can be represented as;
y + 2y + 4y = 70
y is the same as 1y. And when you add y + 2y + 4y, you will get 7y. So
7y=70
Divide the both sides by 7. That will be;
y= 7 . So Rita has 7 fishes. Hope i helped.
Answer:
D
Step-by-step explanation:
Use law of sines
320ft/sin(17) = x ft/sin(128)
x = 862.5
