The expression \[b^{-3\2} , b>0 \] is the equivalent to;
=1/b3/2=1/b3−−√
Answer:
The solution of the first image is: b = √48
The solution of the second image is: c = √125
Step-by-step explanation:
Here we have two triangle rectangles, first, we need to remember the Pythagorean theorem.
For a triangle rectangle with cathetus A and B, and a hypotenuse H, we have the relationship:
A^2 + B^2 = H^2
Where H is the side that is opposite to the right angle (the angle of 90°)
In the first image, we can see that the hypotenuse is equal to 8, and one cathetus is equal to 4.
We want to find the value of b, that is the other cathetus.
Then we have:
4^2 + b^2 = 8^2
b^2 = 8^2 - 4^2
b^2 = 48
b = √48
Second image:
in this case, c is the hypotenuse, a and b are the cathetus.
We know that:
a = 5, b = 10
Then we have the equation:
a^2 + b^2 = c^2
Now we can replace the above values:
5^2 + 10^2 = c^2
25 + 100 = c^2
125 = c^2
√125 = c
Answer:
b is the y-intercept

Answer:
C. (4,2)
Step-by-step explanation:
The point where the lines intersect is (4, 2)
Answer:
80 minutes or 1 hour and 20 minutes
Since Joe can type 60 word per minute, divide 4800 by 60, you will get 80 minutes which is basically 1 hour and 20 minutes.
