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

the second table good luck
Step-by-step explanation:
The student scored 35 in the test
workingout:
70/100 x 50 = 35
to make sure :
35/50 x 100 = 70

Answer:
a).

since sine is in the 2nd quadrant, other angle = 180° - x:

we must make two rotations since it's a double angle:

divide each angle by 2:

Answer = <u>{</u><u>x</u><u>:</u><u> </u><u>x</u><u> </u><u>=</u><u> </u><u>2</u><u>2</u><u>.</u><u>5</u><u>°</u><u>,</u><u> </u><u>6</u><u>7</u><u>.</u><u>5</u><u>°</u><u>,</u><u> </u><u>1</u><u>1</u><u>2</u><u>.</u><u>5</u><u>°</u><u>,</u><u> </u><u>1</u><u>5</u><u>7</u><u>.</u><u>5</u><u>°</u><u>,</u><u> </u><u>2</u><u>4</u><u>7</u><u>.</u><u>5</u><u>,</u><u> </u><u>3</u><u>3</u><u>7</u><u>.</u><u>5</u><u>°</u><u>}</u>
b).

since ans is negative, we take the quadrants of cosine and tangent:

we make three rotations:

answer is <u>{</u><u>z</u><u> </u><u>:</u><u> </u><u>z</u><u> </u><u>=</u><u> </u><u>1</u><u>2</u><u>8</u><u>.</u><u>3</u><u>°</u><u>,</u><u> </u><u>1</u><u>7</u><u>1</u><u>.</u><u>7</u><u>°</u><u>,</u><u> </u><u>2</u><u>3</u><u>1</u><u>.</u><u>7</u><u>°</u><u>,</u><u> </u><u>2</u><u>9</u><u>1</u><u>.</u><u>7</u><u>°</u><u>,</u><u> </u><u>3</u><u>5</u><u>1</u><u>.</u><u>7</u><u>°</u><u>}</u>
