Answer: The answer is -8, 5. Because it is reflecting, it is basically looking at a mirror. Instead of 8 being 8, 8 becomes -8, and -5 becomes 5. If you wouldn't mind, may I have brainliest, unless of course, someone else has a better explanation than mine...

Answer:

X'(8 , 5)

Step-by-step explanation:

Reflection in the x -axis: x will stay the same and y will become opposite

The rule for a reflection over the x -axis is (x,y)-->(x, -y)

In this case

X(8, - 5) ---> X'(8, -(-5)) = X'(8, 5)

Answer

X'(8 , 5)

1. What is an equation of a line, in point-slope form, that passes through (1,-7) and has a slope of -2/3?
Nookie1986 [14]

1. What is an equation of a line, in point-slope form, that passes through (1,-7) and has a slope of -2/3?


Point Slope form y − y1 = m(x − x1)


Y1: -7 x1:1 slope :-2/3


Y-(-7)=-2/3(x-1)

Y+7=-2/3(x-1)


2. What is the equation of a line, in point-slope form, that passes through (-2,-6) and had a slope of 1/3?


Y-(-6)=1/3(x-(-2))


Y+6=1/3(x+2)



3.What is an equation in point-slope form of the line that passes through the points (4,5) and (-3,-1)


SlopeM: =change in y/change in x

M= -1-5/-3-4

M= -6/-7

M=6/7


So now slope:6/7, point (4,5)

Y-y1=m(x-x1)

Equation in point slope

Y-5=6/7(x-4)

Please help me to solve this ∫ 1/(x + √x) dx
skad [1K]

Answer:

\boxed{2ln (\sqrt{x}  + 1 ) + c}

Step-by-step explanation:

\int\limits {\frac{1}{x + \sqrt{x} } } \, dx

= \int\limits {\frac{1}{\sqrt{x} (\sqrt{x}  + 1 )} } \, dx

= \int\limits {\frac{2}{(\sqrt{x}  + 1 )} } \, d(\sqrt{x}  + 1 )

= 2ln (\sqrt{x}  + 1 ) + c

The length of the base of a rectangle prism is 3 feet and its width is 2 feet. The length of the diagonal of the prism is 6 feet
Ede4ka [16]

Answer:

4.8 feet

Step-by-step explanation:

Since length and width of base is 3 and 2 respectively, we find the diagonal of the base with pythagorean theorem.

3^2+2^2=h^2\\9+4=h^2\\13=h^2\\h=\sqrt{13}

This hypotenuse is the base of a triangle with height as the height of the prism and hypotenuse being the hypotenuse of the prism.

So we can again use pythagorean theorem to solve for the height of the prism (let height of prism be x)

(\sqrt{13} )^2+x^2=6^2\\13+x^2=36\\x^2=36-13\\x^2=23\\x=\sqrt{23}

To the nearest tenth, height is 4.8 feet
