Answer:

h'(x) = -10x + 20

Step-by-step explanation:

To get the derivative of $ax^{n}$ , simply use the following formula:

$a(n)x^{n-1}$

We have the function, h(x) = -5x^2 + 20x

Using the formula, we get the derivative to be:

-10x + 20

so h'(x) = -10x + 20

The answer is option D.

Step-by-step explanation:

<u>To find LJ we use the sine rule</u>

From the picture

LK / sin J = LJ / sin K

LK = 9

J = 89°

K = 23°

So now LJ is

9 / sin 89° = LJ / sin 23°

<u>Make LJ the subject</u>

That's

LJ = 9 sin 23° / sin 89°

LJ = 3.51

The final answer is

Hope this helps you.

The length of triangle base is 26. A line, which is parallel to the base divides the triangle into two equal area parts. Find th

Yanka [14]

Answer:

Step-by-step explanation:

It is given that the length of triangle base is 26, then let ABC be the triangle and BC be the base of the triangle=26.Let DE be the parallel line to the base that divides triangle ABC into two equal area parts.

Now, Let AD=a, DB=b, DE=c, AE=d and EC=e, then

Since, triangle ABC is similar to triangle ADE, thus using basic proportions, we get

$\frac{AD}{AB}=\frac{DE}{BC}=\frac{AE}{AC}$

$\frac{AD}{AD+DB}=\frac{DE}{BC}=\frac{AE}{AE+EC}$

$\frac{a}{a+b}=\frac{c}{26}=\frac{d}{d+e}$

Taking the first two equalities,we get

$\frac{a}{a+b}=\frac{c}{26}$

$c=\frac{26a}{a+b}$

Thus, the length of the segment between triangle legs is $\frac{26a}{a+b}$

Solve x=7-2t for t.

yuradex [85]

x=7-2t

Move 7 to the other side. Sign changes from +7 to -7.

x-7=7-7-2t

x-7=-2t

Divide by -2 for both sides

x/-2-7/-2=-2t/-2

x/2+7/2=t

Answer: t= x/2+7/2 or t=7/2+x/2
