Answer:
13
Step-by-step explanation:
It's not 3.25 because if you simplify 6.5 and 0.5, you get 65 and 5 which if you divide is 13.
Answer:
35° (I may be wrong)
Step-by-step explanation:
An isosceles triangle has an interior angle sum of 180° (like all triangles).
So...
180°-40°= 140°
And because we know that isoceles triangles and two congruent sides, we just have to divide 140° by 2.
140°÷2=70°
But the picture says 2h and h is a side so...
70°÷2=35°
The slope of the line shown in the graph is 4.5 .
In the question ,
it is given that ,
the amount of grapes is represented on x axis . and
the cost for that grape in the grocery store is represented on y axis .
to find the slope we need two points on the line ,
from the graph we can take two points as (1 , 4.5) and (2 , 9) ,
the slope can be calculated using the formula
slope = (change in y coordinate)/(change in x coordinate)
slope = (9 - 4.5)/(2 - 1)
slope = 4.5/1
slope = 4.5 .
Therefore , The slope of the line shown in the graph is 4.5 .
The given question is incomplete , the complete question is

Answer:
f(x) = 1/x
Step-by-step explanation:
The corrected question is:
Suppose f is the function that satisfies
f'(x)= - f²(x)
for all x in its domain, and
f(1) = 1
f(x)= ?
Given:
f'(x) = -(f(x))²
This can be written as:
df/dx = -f²
The equation becomes:
-df/f² = dx
Integrating the above equation on both sides we get:
1/f = x + c where c is constant
So
f(x) = 1/(x+c)
Now given that:
f(1) = 1
Solving this for c we get:
f(1) = 1 = 1/(1 + c)
1 = 1/ 1+c
1 = 1 + c
c = 1 - 1
c = 0
Now put this value of c in f(x) = 1/(x+c)
f(x) = 1/(x+0)
f(x) = 1/(x)
f(x) = 1/x
Hence
f(x) = 1/x
