Answer:

Rounding it to two decimal places, we get distance, d=17.35

Step-by-step explanation:

Given:

The two points are (9.7, -2.8)\textrm{ and }(-3.2, 8.8)

The distance between the two points can be obtained using the distance formula which is given as:

d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

Here, for the points, (9.7, -2.8)\textrm{ and }(-3.2, 8.8)

x_{1}=9.7,x_{2}=-3.2,y_{1}=-2.8,y_{2}=8.8

Therefore, the distance between the points is:

d=\sqrt{(-3.2-9.7)^2+(8.8-(-2.8))^2}\\d=\sqrt{(-12.9)^2+(8.8+2.8)^2}\\d=\sqrt{(12.9)^2+(11.6)^2}\\d=\sqrt{166.41+134.56}\\d=\sqrt{300.97}=17.348

Rounding it to two decimal places, we get d=17.35

1.)<br> What is the solution to the system of equations below?<br> y = 2x + 8<br> 3(-2x + y) = 19
-BARSIC- [3]

Answer:

y = 2x + 8

6x + 3y = 19

6x + 3(2x + 8) = 19

6x + 6x + 24 = 19

12x = -5

x = -5/12

y = 2(-5/12) + 8

y = -5/6 + 48/6

y = 43/6

Use Julia’s work and finish finding the areas of the faces what is the surface area of the rectangular pyramid
hoa [83]

Answer:

The surface area of the rectangular pyramid is SA=109.50\ m^{2}

Step-by-step explanation:

we know that

The surface area of the rectangular prism is equal to the area of the rectangular base plus the area of the four triangular faces

so

SA=(8)(5)+2[14.75]+2[\frac{1}{2}(8)(5)]

SA=40+29.50+40

SA=109.50\ m^{2}

What is the volume of a cylinder in a cubic cm,with a height of 8cm and a base diameter of 14 cm?round to the nearest tenth plac
bija089 [108]

Answer:

volume of cylinder = 1232cm³

Step-by-step explanation:

from the question

volume of cylinder =?

height of the cylinder = 8cm

Base diameter of the cylinder = 14cm

to solve this problem we need to know the formula to calculate the volume of a cylinder

volume of cylinder = πr²h

                   or

volume of cylinder = π(d/2)²h........................... if we are given diameter and not radius.

D= 14cm

d = 14/2

d = 7cm

now,

volume of cylinder = π × (7)² × 8

volume of cylinder = 22/7 ×49 ×8

volume of cylinder = 22 × 7 × 8

volume of cylinder = 1232cm³

therefor the volume of the cylinder is equals to 1232cm³
