Step-by-step explanation:

Given data

x1= 3

y1=3

x2=6

y2=16

M= y2-y1/x2-x1

substitute

M=16-3/6-3

M= 13/3

M=4.33

Hence the gradient is 4.33

The surface area of a rectangular prism is 2210 cm2. Two of the dimensions are 5 cm and 10 cm. Find the measure of the other dim
Vlad [161]

The surface area of a rectangular prism is 2210 cm^2 Then the other dimension is 70.3 cm

<h3><u>Solution:</u></h3>

Given that surface area of rectangular prism is 2210 square centimeter

Also given that two of dimensions are 5 cm and 10 cm

To find: other dimension

<em><u>The total surface area of the rectangular prism is gievn as:</u></em>

\text {Total surface area }=2(lb+b h+h l)

Where, "l" is the length and "b" is the breadth and "h" is the height

The given values are:  l = 5cm and b = 10cm

On substituting the given values in formula we get,

\begin{array}{l}{2210=2(l \times b+b \times h+h \times l)} \\\\ {2210=2(5 \times 10+10 \times h+h \times 5)} \\\\ {2210=2(50+10 h+5 h)} \\\\ {1105=50+15 h} \\\\ {1055=15 h} \\\\ {h=70.3}\end{array}

Thus the other dimension is 70.3 cm

Find the distance between each pair of points. Leave your answers in simplest radical form.
Oksanka [162]

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

1. (6, 8), (5, 5). Substitute:

d=\sqrt{(5-6)^2+(0-8)^2}=\sqrt{(-1)^2+(-8)^2}=\sqrt{1+64}=\sqrt{65}

2. (-3, -2), (-5, 3). Substitute:

d=\sqrt{(-5-(-3))^2+(3-(-2))^2}=\sqrt{(-2)^2+5^2}=\sqrt{4+25}=\sqrt{29}
