Answer:
8.88
Step-by-step explanation:
With reference angle 42°
hypotenuse (h) = 12
base (b) = x
Now
cos 42° = b / h
0.74 = x / 12
x = 0.74 * 12
x = 8.88
Answer:
f(x) = (x - 10) (x + 10)
Step-by-step explanation:
The equation looks like the difference of squares so 5 and 20 are out
-10 x -10 = 100
-10 x 10 = - 100
so (x - 10) (x + 10)
Answer:
the answer is C

<u>Given </u><u>:</u><u>-</u><u> </u>
<u>To Find :- </u>
<u>Solution</u><u> </u><u>:</u>
Let ,
→ y = f(x)
So that ,
→ y = 4x - 10/ x -2
- For finding x intercept , substitute y = 0 .
→ 0 = 4x - 10/x - 2
→ 4x - 10 = 0
→ 4x = 10
→ x = 10/4
→ x = 5/2
→ x = 2.5
- For finding y intercept , put x = 0 .
→ y = 4*0 - 10 / 0 -2
→ y = -10/-2
→ y = 5
- x intercept = (2.5,0)
- y intercept = (0,5)
