Answer:

D

y-5=3(x+1)

Step-by-step explanation:

We can see that the question is asking for the Point-Slope Form;

y-y_{1} =m(x-x_{1})

The points go into the equation for y_{1} and x_{1}

y-5=m[x-(-1)]

M would be the slope;

y-5=3[x-(-1)]

Which basically is:

y-5=3(x+1)

Find the volume of a cone of radius 49cm and height 10cm​
den301095 [7]

Answer:

<h2> 25154.34{cm}^{3}</h2>

Step-by-step explanation:

Given,

Radius ( r ) = 49 cm

Height (h) = 10 cm

Volume of cone=?

Now,

Applying the formula to find the volume of cone:

\pi \:  {r}^{2}  \frac{h}{3}

Plugging the values,

\frac{22}{7}  \times  {49}^{2}  \times  \frac{10}{3}

\frac{22}{7} \times 2401 \times  \frac{10}{3}

Calculate

25153.34  \:  {cm}^{3}

Hope this helps...

Good luck on your assignment..

1) Where is the midpoint of , when A (6, 7) and B (-9, -5)?
lord [1]

Answer:

(−1.5,1)

Step-by-step explanation:

Finding the distance, midpoint, slope, equation and the x y-intercepts of a line passing between the two points p1 (6,7) and p2 (-9,-5)

The distance (d) between two points (x1,y1) and (x2,y2) is given by the formula

d = √  ((X2-X1)2+(Y2-Y1)2)

d = √ (-9-6)2+(-5-7)2

d = √ ((-15)2+(-12)2)

d = √ (225+144)

d = √ 369

The distance between the points is 19.2093727122985

The midpoint of two points is given by the formula

Midpoint= ((X1+X2)/2,(Y1+Y2)/2)

Find the x value of the midpoint

Xm=(X1+X2)/2

Xm=(6+-9)/2=-1.5

Find the Y value of the midpoint

Ym=(Y1+Y2)/2

Ym=(7+-5)/2=1

The midpoint is: (-1.5,1)
