I dont know how to solve these
Ne4ueva [31]

Answer:

137°

Step-by-step explanation:

So, both are equal to each other due to them being the same degree angle.

5x+7=8x-71

subtract 5x on both sides

7=3x-71

add 71 to both sides

77=3x

divide both sides by 3

77/3=x

x equals about 26

insert x into the problems

[5(26)+7]°

this equals 137°

[8(26)-71]°

this equals 137°

∫∫x²(y-x)dxdy ,d là miền giới hạn bởi các đường y=x² và x=y²
Valentin [98]

It looks like the integral is

\displaystyle \iint_D x^2 (y-x) \,\mathrm dx\,\mathrm dy

where <em>D</em> is the set

<em>D</em> = {(<em>x</em>, <em>y</em>) : 0 ≤ <em>x</em> ≤ 1 and <em>x</em> ² ≤ <em>y</em> ≤ √<em>x</em>}

So we have

\displaystyle \iint_D x^2(y-x)\,\mathrm dx\,\mathrm dy = \int_0^1 \int_{x^2}^{\sqrt x} x^2(y-x)\,\mathrm dy\,\mathrm dx \\\\ = \int_0^1 \left(\frac{x^2y^2}2-x^3y\right)\bigg|_{y=x^2}^{y=\sqrt x} \\\\ = \int_0^1 \left(\frac{x^3}2-x^{7/2}+x^5-\frac{x^6}2\right)\,\mathrm dx \\\\ = \left(\frac{x^4}8 - \frac{2x^{9/2}}9 + \frac{x^6}6 - \frac{x^7}{14}\right)\bigg|_{x=0}^{x=1} = \frac18-\frac29+\frac16-\frac1{14} = \boxed{-\frac{1}{504}}

Could someone help me with number 5 because I suck at perimeters
N76 [4]
You might need to use the distance formula

for the distance betwen (x1,y1) and (x2,y2) is
D= \sqrt{(x1-x2)^2+(y1-y2)^2}

so find disance between (-3,1) and (-1,3)
and (-1,3) and (3,1)
so
if we did input them
we would get 6+2 \sqrt{2}+2 \sqrt{5} which is the peirmiter
