Answer:
53
Step-by-step explanation:
if f(a)= -11 the the equation is: 20-3(-11)
First, multiply -3 and -11:
20-3×(-11)
20+33
Now, add:
20+33= <u>53</u>
<u></u>

Answer:
y = root under 24 (evaluate it if necessary)
or y = 2 root 6
Step-by-step explanation:
Let the reference angle be x
for the triangle in left,
b = 6-4 = 2
Now,
taking x as refrence angle,
cosx = b/h
or, cosx = 2/h
again,
for the bigger triangle,
taking x as reference angle,
cosx = b/h
or, cosx = b/6
As we can see base of bigger triangle is equal to hypotenuse of triangle at the left,
Let's suppose its a
so, cosx = a/6 = 2/a
now,
a/6 = 2/a
or, a² = 12
now,
for bigger triangle, using pythagoras theorem,
h² = p²+b²
or, 6² = y² + a²
or, 36 = y² + 12
or, y² = 24
so, y = root under 24
Answer:
4 1/3
Step-by-step explanation:
10 - 5 2/3
30/3 - 17/3 = 13/3 = 4 1/3
C) 1 makes the most sense
