Answer:

Step-by-step explanation:

The graph begins up and ends down. This means as x heads into negative infinity the graph continues up, up and up towards infinity. While x heads to positive infinity on the right side of the graph, the graph heads down, down, and down towards negative infinity. See graph below.

How much larger would the volume of a prism be if it was increased by a scale factor of 5

jek_recluse [69]

We know that

if the volume of a prism <span>it was increased by a scale factor of 5
then
</span>the original volume is multiplied by 5*5*5-------> 5³=125

therefore
the new volume compared with the original is 125 times larger

A circle has a diameter of 14 feet. What is the circumference of the circle? Use 3:14 for pie.

Marianna [84]

Answer:

Circumference= $43.96 feet$

Step-by-step explanation:

Diameter of the circle= 14 feet

Radius of the circle= 14/2= 7 feet

Circumference of the circle= $2\pi r$

As, $\pi =\frac{22}{7}=3.14$

Circumference:

$=2*3.14*7\\\\=3.14*14\\\\=43.96feet$

The circumference of the circle with the radius= 7 feet is $43.96 feet$

a (1,4) b (-1,2) c (5,-2) are the vertices of triangle abc find the sum of coordinates of the point where the right bisector of

zmey [24]

Answer:

Step-by-step explanation:

Find the midpoint of BC:

midpoint = (-1+5)/2, (2-2)/2 = (2, 0).

The slope of BC = (2 - -2) / (-1-5) = -2/3.

Find the equation of the right bisector of BC:

The slope = -1 / -2/3 = 3/2.

y-y1 = m(x-x1)

y - 0 = 3/2(x - 2)

y = 3/2x - 3.

Now find the equation of the median through C:

The midpoint of AB = (1 - 1)/2, (4+2)/2

= (0, 3).

The equation of the median:

The slope = (-2-3) / (5-0)

= -1.

The equation is:

y - 3 = -1(x - 0)

y -3 = -x.

Now we find the point of intersection by solving the 2 equations:

y - 3 = -x

y = 3/2x - 3

y = -x + 3

So:

3/2x - 3 = -x + 3

3/2x + x = 6

5/2 x = 6

x = 12/5.

y = -12/5 + 3

= -12/5 + 15/5

= 3/5.

The sum of the coordinates = 12/5 + 3 /5

= 15/5

= 3.
