Answer:
C)
Step-by-step explanation:
u = x + 1
u - 1 = x
[tex]\int\limits {\dfrac{x}{\sqrt{x+1}}} \, dx = \int\limits {\dfrac{u-1}{\sqrt{u}}} \, du \\\\[/tex]
[tex]=\int {\left(\dfrac{u}{u^{\frac{1}{2}}}-\dfrac{1}{u^{\frac{1}{2}}} \right )\, du \\\\ = \int {u^{1-\frac{1}{2}}-1*u^{\frac{-1}{2}}} \, du\\\\ =\int {(u^{\frac{1}{2}}-u^{\frac{-1}{2}})} \, du[/tex]

The question is asking for the midpoint of the line.
The triangle is formed by placing a line directly from the y-axis to the x-axis.
The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].
your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.
Your coordinates for B are (100;0)
C[(x1+x2)/2 ; (y1+y2)/2 ]
C [(0+100)/2 ; (-40+0)/2 ]
C[ 100/2 ; -40/2]
C (50 ; -20)

The volume of the ball has a diameter of 15 centimeters around 2 decimal places is 1767.15 cubic centimeters.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
A sports ball has a diameter of 15 cm.
Then the radius of the ball will be
r = d/2
r = 15/2
r = 7.5 cm
Then the volume of the ball will be
[tex]\rm Volume = \dfrac{4}{3} \times \pi \times r^3\\\\Volume = \dfrac{4}{3} \times \pi \times 7.5^3\\\\Volume = \dfrac{4}{3} \times \pi \times 421.875\\\\Volume = 1767.15\ cm^3[/tex]

The problem is put in different fractions to make it more confusing.
1 1/15 miles+ 1 3/5 miles+ 1 2/3 miles
We can find the common denominator of all of the fractions.
[tex]1 \frac{1}{15} + 1 \frac{9}{15} + 1 \frac{10}{15} \\= 3+\frac{20}{15} =4 \frac{5}{15}\\\\=[/tex]4 1/3
[tex]monday = 1 \frac{1}{15} [/tex]
[tex]tuesday = 1 \frac{3}{5} [/tex]
[tex]wednesday = 1 \frac{2}{3} [/tex]
to find:the total number of miles Kenya ran in 3 days.
solution:[tex] \frac{16}{15} + \frac{8}{5} + \frac{5}{3} [/tex]
[tex] = \frac{16}{15} + \frac{8 \times 3}{5 \times 3} + \frac{5 \times 5}{3 \times 5} [/tex]
[tex] = \frac{16 + 24 + 25}{15} [/tex]
[tex] = \frac{65}{15} = \frac{13}{3} [/tex]
[tex] = 4 \frac{1}{3} [/tex]
therefore, the correct answer is option D.

A: (x, y) → (x + 1, y + 2); (-2, 6)
Step-by-step explanation:
The A vertex started at (-3, 4), [ x = (-3) , y = 4 ]The triangle translates two units up meaning y+2The trinalge also translates one unit to the right meaning x+1, but if it was to the left it would be minus, since we are basically graphing x and y.Equation needs to have x + 1 and y + 2 which is only found in the answer A equation. (x + 1, y + 2)Verify X and Y final vertex. x originally equalled (-3), if we take that integer and +1 we get (-2). and the same for y, y originally equalled 4, if we take that number and +2 we get 6.which makes (-2, 6)Which perfectly equals our selected equation. The answer is A.
Hope this helped :)
