Answer:
64
Step-by-step explanation:
its subtracting the square of the numbers
169-7²= 120
120-6²=84
84-5²=59
59-4²=43
43-3²=34
34-2²=30
so the sum is 64
Volume = Area of triangle x length
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 5 x 4
Area of triangle = 10
Volume = area of triangle x length
Volume = 10 x 12
Volume = 120 cm^3
Hello:
f(x) =6sin(x)
f'(x) = 6 cos(x)
the equation of the tangent line is : y=f'(π/6)(x-π/6)+f(<span>π/6)
f'(</span>π/6)=6cos(π/6)=6×(√3/2)=3<span>√3
f(</span>π/6) =3
the equation is : y = 3√3(x-π/6)+3
So the whole goal of this is to get the variable (z) all by itself on one side with a coefficient (the number in front of the variable (z)) of one. All you have to do is add seven to each side to get z alone and then divide by two:
2z-7< or equal to 1
+7
2z< or equal to 8
/2
z< or equal to 4
The slope is -0.8 and all values of x are > -3
So its the last option.
