Step-by-step explanation:

In circle with centre O, TN is tangent at E.

\therefore OE \perp TN\\\\\therefore m\angle OET = m\angle OEN= 90\degree \\\\In\: \triangle OET\\\\\angle OET + \angle OTE +\angle TOE = 180°\\\\\therefore 90\degree + 35\degree+\angle TOE = 180°\\\\\therefore 125\degree+\angle TOE = 180\degree\\\\\therefore \angle TOE = 180\degree-125\degree\\\\\huge \red {\boxed{\therefore \angle TOE = 55\degree}} \\\\In\: \triangle OPE\\\\OP = OE... (radii\: of \:same \: circle) \\\\\therefore \angle OPE = \angle OEP..(1)\\  (\angle s \: opposite \: to \:equal\:sides) \\\\\angle TOE =\angle OPE +\angle OEP.. (2)\\(by\:exterior \:\angle\:theorem) \\\\\therefore 55\degree= \angle OPE +\angle OPE\\\{From\: equations\:(1) \&\:(2)\} \\\\\therefore 55\degree= 2\angle OPE \\\\\therefore \angle OPE = \frac{55\degree}{2}\\\\\huge \orange{\boxed{\therefore \angle OPE =27.5\degree}}

Suppose y varies inversely with x, and y = 25 when x = 1/5. What is the value of y when x = 5 ?
34kurt

Answer:

y = 1

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition y = 25 when x = \frac{1}{5} , then

25 = \frac{k}{\frac{1}{5} } = 5k ( divide both sides by 5 )

5 = k

y = \frac{5}{x} ← equation of variation

When x = 5, then

y = \frac{5}{5} = 1

The <em>speed</em> intervals such that the mileage of the vehicle described is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h]

<h3>How to determine the range of speed associate to desired gas mileages</h3>

In this question we have a <em>quadratic</em> function of the <em>gas</em> mileage (g), in miles per gallon, in terms of the <em>vehicle</em> speed (v), in miles per hour. Based on the information given in the statement we must solve for v the following <em>quadratic</em> function:

g = 10 + 0.7 · v - 0.01 · v²      (1)

An effective approach consists in using a <em>graphing</em> tool, in which a <em>horizontal</em> line (g = 20) is applied on the <em>maximum desired</em> mileage such that we can determine the <em>speed</em> intervals. The <em>speed</em> intervals such that the mileage of the vehicle is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h].

If you have 186 pencils, how many how many will each person get in a class that has 23 students?
Brut [27]
