The answer is 3.12 thank me later ;)
You divide by 5/13. Remember when dividing fractions you multiply by the reciprocal. 5/13 cancels on the left side, leaving t.
So here you have -9/(5/13), but we can put -9 as -9/1, then instead of dividing by 5/13, multiply by 13/5: 117/5. This evens out, when divided, to t=23.4
Answer:
Step-by-step explanation:
Let
x ----> the number of hours
y ----> the cost in dollars
we know that
The linear equation in slope intercept form is equal to
where'
m is the slope or unit rate
b is the y-intercept of initial value
In this problem
we have
The slope is equal to
The y-intercept or initial value is equal to
therefore
The linear equation in slope intercept form is equal to
Answer:
D; 5pi/3 units
Step-by-step explanation:
Here, we want to find the period of the function;
y = 3/2 cot (3/5x) + 5
By definition, the period of a function is the interval between two matching points in the function.
Let’s say it is the distance between two peaks, crests, etc on a function.
To find the value of the period. We shall standardize the function.
What this means is that we shall be writing the function in the standard form.
The standard form is as follows;
f(x) = A trig(Bx -C) + D
Where trig refers to the accompanying trigonometric function in question.
Comparing this standard form with our question, we can see that;
A is 3/2
B is 3/5
C is 0
D is 5
Now for cot and tan functions, we shall need to divide pi by the absolute value of B
Thus we have; pi divided by 3/5 which gives 5pi/3 units
Answer:
x = 15
Step-by-step explanation:
Given
5(x - 10) = 25 ( divide both sides by 5 )
x - 10 = 5 ( add 10 to both sides )
x = 15
