Answer:
4
Step-by-step explanation:
We know that oppostie sides of a rectange have to be equal
therefore
18=10+2x
solve for x
8=2x
x=4
We need to know the volume of the tea glasses in order to know how much tea she needs... but we're only given the height of the tea glasses. We do not know the radius or diameter of the tea glasses, so we cannot solve for the volume of the tea glasses. Therefore there isn't enough information to answer the question.
3:
You're finding the area of two shapes, a square, and a quarter of a circle.
So
A=As+Ac/4
A=Lw+πr²/4
A=(6)(6)+(3.14)(6²)/4
A=64.26 m²
4:
Line LKJ is a straight line, so <LKJ =180°
<LKJ=<JKH+<HKL
180=78+4x+2
180=80+4x
100=4x
25=x
<HKL=4x+2
<HKL=4(25)+2
<HKL=102°
Answer:
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given y = cos² (x² + x³) ....(i)
By using differentiation formulas
a)
b)
<u><em>Step(ii):-</em></u>
Differentiating equation (i) with respective to 'x'
<em>First apply formula </em><em></em>
<em>Now we will apply formula </em>
<em>Again apply formula </em><em></em>
we know that trigonometric formulas
Sin 2θ = 2 sinθ cosθ
<u><em>Final answer:-</em></u>
