By the chain rule,

$\dfrac{\mathrm d(f\circ c)}{\mathrm dt}=\nabla f(c(t))\cdot\dfrac{\mathrm dc}{\mathrm dt}$

When $t=\pi$ , the derivative has a value of

$\nabla f(c(\pi))\cdot c'(\pi)=\nabla f(1,1,\pi,e^6)\cdot(18,13,0,1)=(0,1,3,-9)\cdot(18,13,0,1)=0+13+0-9=4$

I am trying to understand how to solve for X, then solve the equation

Alina [70]

Answer:

x = 16

m<Y = 34°

Step-by-step explanation:

∆XYZ is an isosceles ∆. An isosceles ∆ has two equal sides, as well as the bases of the isosceles triangle are congruent. In this case, therefore:

<X = <Z

(6x - 23)° = (4x + 9)

Solve for x

6x - 23 = 4x + 9

Collect like terms

6x - 4x = 23 + 9

2x = 32

Divide both sides by 2

x = 16

m<Y = 180° - (m<X + m<Z) (sum of ∆)

m<Y = 180 - ((6x - 23) + (4x + 9))

Plug in the value of x

m<Y = 180 - ((6(16) - 23) + (4(16) + 9))

m<Y = 180 - (73 + 73)

m<Y = 34°

How would you convert 93/20 to a decimal?

anastassius [24]

In order for you to find the decimal for this problem you would have to divide both of the numbers from each other.

So for this problem you have to

Problem → $\frac{93}{20}$

Write them out → 93 ÷ 20

Answer → 4.65

So, that means that your answer is 4.65
