The pair of points defines a line with a slope of -1 is C. (10,3) and (15,-2)
A unit fraction means that the fraction has 1 in the numerator. To make 3/8 a unit fraction, you have to make it 1/8 by dividing by 3.
So now you have 3 x 3 x 1/8. You can multiply the 3 and 3.
You are left with 9 x 1/8.
Answer:
6.2
Step-by-step explanation:
The lines represent absolute value, all your doing is changing it to a positive number which is 6.2
If the question asked What is the evaluate of I6.2I, the answer would be 6.2, it is always a positive number
A= -2
B= 4
C= -3
The equation the help you with this for later reference is **ax^2 + bx + c=0**
Help you answer the questions, sure! Do the problems for you, nope.
in Problem 26 you have 2 small triangles. In the left one you have the angle 36 degrees, which means that the other acute angle is 90-36, or 54 (degrees). You'll need to find the height of the left triangle; finding that height is the same as determining the length of the side adjacent to the 36 degree angle.
Let that height be repr. by h.
Then tan 36 deg = h/21 Use the inverse tangent function to find the value of h.
Look at the triangle on the right. It has a 42 deg angle, and the length of the side next to it is h (which you found above). x is the hypotenuse.
Can you see that x*cos 42 deg = h? Knowing h, can you now find x?
If you have any qu. about this approach, please ask questions.
