Answer:

3.162278

Step-by-step explanation:

d = √ (−3 − ( −6 ) )^2 + ( 9 − 8 )^2

d = √(3)^2+(1)^2

d = √9+1

d = √10

d = 3.162278

Find the difference. write your answer as a fraction in simplest form. 5/8-(-7/8)
Lubov Fominskaja [6]

Answer:

1 1/2

Step-by-step explanation:

When you are subtracting a negative number is is the same as adding a positive.  So the problem is really 5/8 + 7/8, since the denominators are the same, just add the numerators to get 12/8  divide the top and bottom by 4 to get 3/2 or 1 1/2, if I divide 3 by 2.

a doctor's prescription for a daily intake of 40 mg of vitamin C and 30 mg of vitamin D your Pharmacy stocks two compounds that
lbvjy [14]
Hi,
Let's say we need x mg from 1st compound, and y mg from 2nd compound.

0.20 × x + 0.40 × y = 40mg
0.30 × x + 0.20 × y = 30mg

0.20(x + 2y) = 40. => x + 2y = 200 => 2y=200-x
0.10(3x +2y) = 30. => 3x + 2y = 300

3x + (200 - x) = 300
2x = 100
x =50mg

50 + 2y = 200
2y = 150
y =75mg

Between which two ordered pairs does the graph of f(x) = one-halfx2 + x – 9 cross the negative x-axis?
Anit [1.1K]

Answer:

Step-by-step explanation:

we have that

f(x) = x^2 + x - 9

Using a graph tool

see the attached figure

The function represent a vertical parabola that open up

the vertex is a minimum-------> is the point (-0.5, -9.3)

The x-intercepts are the points when the y coordinate is equal to zero

The x-intercepts are the points (-3.5, 0)  and (2.5, 0)

so

the function cross the negative x-axis at point

therefore, the answer is

(-4, 0) and (-3, 0)
