Answer: 39 25/50
Step-by-step explanation:
0.78 ( 78% ) = 39/50
0.79 ( 79% ) = 39/50 + 1/2
25 is half of 50
39 25/50
Answer:
The slope is -3/4 and a point on the line is (-5,4)
Step-by-step explanation:
This equation is in point slope form
y -y1 = m(x-x1)
where m is the slope and (x1,y1) is a point on the line
Y-4=-3/4(x+5)
Y-4=-3/4(x - -5)
The slope is -3/4 and a point on the line is (-5,4)
For this case what we must observe are the following triangles:
ADB
BDC
According to the diagram, the triangles have exactly the same dimensions.
Therefore, it is fulfilled:
Then, the value of AC is given by:
Substituting values we have:
Answer:
The value of AC is given by:
option 3
Answer:
6√2
Step-by-step explanation:
According to the question
The equation is
Sin(45°)=6/x
√2/2=6/x
√2x=12
x=12/√2
x=12×√2/√2²
x=12×√2/2
x=6√2
Answer:
The average rate of change of f(x) = x + 6 on [4,9) is 1.
Step-by-step explanation:
Given a function y, the average rate of change S of in an interval will be given by the following equation:
In this problem, we have that:
Interval [4,9]
Continuous function(no denominator or even root), this is why i can consider 9 a part of the interval for the calculation. So
.
So
The average rate of change of f(x) = x + 6 on [4,9) is 1.
