$4(20+1)=4(20)+4(1)=80+4=84$

It's still just easier to add first though.

Answer:

2 ( Option A )

Step-by-step explanation:

The given integral to us is ,

$\longrightarrow \displaystyle \int_0^1 5x \sqrt{x}\ dx$

Here 5 is a constant so it can come out . So that,

$\longrightarrow \displaystyle I = 5 \int_0^1 x \sqrt{x}\ dx$

Now we can write √x as ,

$\longrightarrow I = \displaystyle 5 \int_0^1 x . x^{\frac{1}{2}} \ dx$

Simplify ,

$\longrightarrow I = 5 \displaystyle \int_0^1 x^{\frac{3}{2}}\ dx$

By Power rule , the integral of x^3/2 wrt x is , 2/5x^5/2 . Therefore ,

$\longrightarrow I = 5 \bigg( \dfrac{2}{5} x^{\frac{5}{2}} \bigg] ^1_0 \bigg)$

On simplifying we will get ,

$\longrightarrow \underline{\underline{ I = 2 }}$

Solve the equation.

Vika [28.1K]

Hey there!!

Equation given :

... 78 = -2 ( m + 3 ) + m

... 78 = -2m - 6 + m

... 78 = -m - 6

... 78 + 6 = -m

... 84 = -m

... m = -84

Hope my answer helps!!

Calculate to the nearest 1/10th meter the length of the side of a 7th, 12th, and 30th hectare square plot.

Tems11 [23]

Answer and explanation:

To find : Calculate to the nearest 1/10th meter the length of the side of a 7th, 12th, and 30th hectare square plot.

Solution :

The area of the square is given by,

$A=s^2$ where s is the side length.

We know, $1 \text{ hectare}=10,000\ m^2$

1) The area of square plot is 7 hectare.

Area in meter square is $A=7\times 10000=70000\ m^2$

Substitute the value in the formula,

$70000=s^2$

$\sqrt{70000}=s$

$264.57=s$

Side nearest to 1/10th meter is 264.8 meter.

2) The area of square plot is 12 hectare.

Area in meter square is $A=12\times 10000=120000\ m^2$

Substitute the value in the formula,

$120000=s^2$

$\sqrt{120000}=s$

$346.41=s$

Side nearest to 1/10th meter is 346.4 meter.

3) The area of square plot is 30 hectare.

Area in meter square is $A=30\times 10000=300000\ m^2$

Substitute the value in the formula,

$300000=s^2$

$\sqrt{300000}=s$

$547.72=s$

Side nearest to 1/10th meter is 547.7 meter.
