Answer:

12.32

Step-by-step explanation:

So by using y1 +y2/x1+x2 we can find the ratio.

the y1 will be 4 and y2 will be 13.

the x1 will be 5 and x2 will be 6

this is equivilent to 17/11 (4+13/5+6)

17/11 =1.54545454... we can simplify to 1.54

8*1.54=12.32

this might be wrong I haven't done this math in years

Differentiate... How to solve this type of problem? y = cos^2(x^2 + x^3)

Licemer1 [7]

Answer:

$\frac{d y}{d x} = - (2 x + 3 x^{2} )sin2(x^{2} +x^{3})$

Step-by-step explanation:

Step(i):-

Given y = cos² (x² + x³) ....(i)

By using differentiation formulas

a) $\frac{d}{dx} (cosx) = -sinx$

b) $\frac{d}{dx} (x^{n} ) = n x ^{n-1}$

Step(ii):-

Differentiating equation (i) with respective to 'x'

First apply formula $\frac{d}{dx} (x^{n} ) = n x ^{n-1}$

$\frac{d y}{d x} = 2 cos (x^{2} +x^{3} )^{2-1} \frac{d}{d x} (cos(x^{2} +x^{3})$

Now we will apply formula

$\frac{d}{dx} (cosx) = -sinx$

$\frac{d y}{d x} = 2 cos (x^{2} +x^{3} ) (-sin(x^{2} +x^{3})\frac{d}{dx} (x^{2} +x^{3} )$

Again apply formula $\frac{d}{dx} (x^{n} ) = n x ^{n-1}$

$\frac{d y}{d x} = 2 cos (x^{2} +x^{3} ) (-sin(x^{2} +x^{3}) (2 x + 3 x^{2} )$

$\frac{d y}{d x} = -2 sin (x^{2} +x^{3} ) cos(x^{2} +x^{3}) (2 x + 3 x^{2} )$

we know that trigonometric formulas

Sin 2θ = 2 sinθ cosθ

$\frac{d y}{d x} = -sin2(x^{2} +x^{3}) (2 x + 3 x^{2} )$

Final answer:-

$\frac{d y}{d x} = - (2 x + 3 x^{2} )sin2(x^{2} +x^{3})$

What is the area of the trapezoid shown below? units2

mylen [45]

Answer and Step-by-step explanation:

Use the Pythagorean Theorem to solve for the height.

$a^{2}+ b^{2}= c^{2} \\\\\\4^{2} + b^{2} = 5^{2}\\\\\\16 + b^{2} = 25\\\\\\b^{2} = 9\\\\\\b = 3$

The height of the triangle is 3.

Now we can solve the shapes in the trapezoid.

4 times 3 = 12 (Rectangle)

$\frac{4 * 3}{2}$ = $\frac{12}{2}$ = 6 (Triangle)

12 + 6 = 18 (Trapezoid)

The area of the trapezoid is 18 $units^{2}$ .
