Hello!

New value =

20 + Percentage increase =

20 + (50% × 20) =

20 + 50% × 20 =

(1 + 50%) × 20 =

(100% + 50%) × 20 =

150% × 20 =

150 ÷ 100 × 20 =

150 × 20 ÷ 100 =

3,000 ÷ 100 =

30;
<span>20 increased by 50% = <span>30 </span>
<span>Absolute change (actual difference): <span>30 </span>- 20 = 10


Hope this Helps! Have A Wonderful Day! :)</span></span>

Consider the curve defined by the equation y=6x2+14x. Set up an integral that represents the length of curve from the point (−2,
torisob [31]

Answer:

32.66 units

Step-by-step explanation:

We are given that

y=6x^2+14x

Point A=(-2,-4) and point B=(1,20)

Differentiate w.r. t x

\frac{dy}{dx}=12x+14

We know that length of curve

s=\int_{a}^{b}\sqrt{1+(\frac{dy}{dx})^2}dx

We have a=-2 and b=1

Using the formula

Length of curve=s=\int_{-2}^{1}\sqrt{1+(12x+14)^2}dx

Using substitution method

Substitute t=12x+14

Differentiate w.r t. x

dt=12dx

dx=\frac{1}{12}dt

Length of curve=s=\frac{1}{12}\int_{-2}^{1}\sqrt{1+t^2}dt

We know that

\sqrt{x^2+a^2}dx=\frac{x\sqrt {x^2+a^2}}{2}+\frac{1}{2}\ln(x+\sqrt {x^2+a^2})+C

By using the formula

Length of curve=s=\frac{1}{12}[\frac{t}{2}\sqrt{1+t^2}+\frac{1}{2}ln(t+\sqrt{1+t^2})]^{1}_{-2}

Length of curve=s=\frac{1}{12}[\frac{12x+14}{2}\sqrt{1+(12x+14)^2}+\frac{1}{2}ln(12x+14+\sqrt{1+(12x+14)^2})]^{1}_{-2}

Length of curve=s=\frac{1}{12}(\frac{(12+14)\sqrt{1+(26)^2}}{2}+\frac{1}{2}ln(26+\sqrt{1+(26)^2})-\frac{12(-2)+14}{2}\sqrt{1+(-10)^2}-\frac{1}{2}ln(-10+\sqrt{1+(-10)^2})

Length of curve=s=\frac{1}{12}(13\sqrt{677}+\frac{1}{2}ln(26+\sqrt{677})+5\sqrt{101}-\frac{1}{2}ln(-10+\sqrt{101})

Length of curve=s=32.66

2.37 / x = 1<br> What is x?
NeTakaya

Answer: 2.37

Step-by-step explanation:

Multiply each side by x to get  rid of the denominator on the left side.

You get:

2.37 = 1x

1x = x

Therefore, 2.37 = x.

Also, any number divided by itself must be 1.

Find the area of the following triangle. Show each of the math steps that you use to find the area. Then explain how to go about
Diano4ka-milaya [45]

Semi perimeter:-

\\ \rm\rightarrowtail s=\dfrac{a+b+c}{2}

\\ \rm\rightarrowtail s=\dfrac{1.8+2.4+3}{2}

\\ \rm\rightarrowtail s=\dfrac{7.2}{2}=3.6cm

Apply heron s formula

Area:-

\\ \rm\rightarrowtail \sqrt{s(s-a)(s-b)(s-c)}

\\ \rm\rightarrowtail \sqrt{3.6(3.6-1.8)(3.6-3)(3.6-2.4)}

\\ \rm\rightarrowtail \sqrt{3.6(1.8)(0.6)(1.2)}

\\ \rm\rightarrowtail \sqrt{4.6656}

\\ \rm\rightarrowtail 2.16cm^2
