The Correct answer is 3

Explanation:

Using the defined function, f(a) will produce the same result when substituted for x:

F(x)=x^2-x^3

Setting this equal to 4, you can solve for a:

a2 – 5 = 4

a2 = 9

a = –3 or 3

Bumek [7]

Answer:

$AB = 21.3$

Step-by-step explanation:

Given

$\sin(25) = \frac{9}{c}$

See attachment

Required

Find AB

We have:

$\sin(25) = \frac{9}{c}$

Make c the subject

$c = \frac{9}{\sin(25)}$

$c = 21.3$

From the attached triangle;

$AB = c = 21.3$

Hence:

$AB = 21.3$

PLEASE TELL ME ITS ANSWER

Dafna11 [192]

Step-by-step explanation:

6) x+y=60

x/y=7/5------(2)

x=(7/5)y

(7/5)y + y =60

(12/5)y=60

y=60(5/12)

y= 25

x=(7/5)y=(7/5)×25 =35

the two numbers are 35 and 25
