Answer:
(17,0) and (-2,19)
Step-by-step explanation:
First, find the gradient of AB, which is 1. As CD is perpendicular, its gradient will be -1. The equation of CD will be y=17-x. The x intercept is where y=0. So, that will give you x=17. When x=-2, y=19. It proves the equation right.
Answer:
The area under the standard normal curve to the left of z=−2.94 and to the right of z=−2.28 is 0.9903 square units.
Step-by-step explanation:
We need to find the area under the standard normal curve to the left of z=−2.94 and to the right of z=−2.28.
The standard normal table represents the area under the curve.
.....(1)
According to the standard normal table, we get
Substitute these values in equation (1).
Therefore the area under the standard normal curve to the left of z=−2.94 and to the right of z=−2.28 is 0.9903 square units.
"zeros" are solutions for x that make the equation equal to zero.
(x - 8)(x + 8)(x - 1) = 0
Answer:
5/2=2.5, while 1/3= aprox 0.333, therefore 5/2 is not equal to 1/3.
Step-by-step explanation:
Here is the long division table for 5/2
2. 5 0 0
2 5. 0 0 0
− 4
1 0
− 1 0
0 0
− 0
0 0
− 0
0
Here is the long division table 1/3 ( to three decimal places)
0. 3 3 3
3 1. 0 0 0
− 0
1 0
− 9
1 0
− 9
1 0
− 9
1
An easier way to do 5/2 is to think of 50/2, which is 25, and then add a decimal point, making it 2.5.
An easier way to do 1/3 is to think of it as one third (of one), or 0.333 repeating.
