Describe the process of creating a linear equation using two points and the point-slope form.
faltersainse [42]
First find the slope of the line = (y2 - y1) / (x2 - x1)   where the 2 points are (x1, y1 and (x2, t2). 

Then  substitute the values of  the slope (m) and one of the points   into the point-slope formula

y - y1 = m(x - x1)

A pole 5 feet tall is used to support a guy wire for a tower, which runs from the tower to a metal stake in the ground. After pl
sammy [17]

The length of the guy's wire to the nearest foot is 89 feet.

The situation forms a right-angled triangle.

<h3>Properties of a right angle triangle:</h3>
  • A right-angle triangle has one angle of 90 degrees.
  • The sides can be found using the Pythagoras theorem.
  • The angles can be found using trigonometric ratios.

The hypotenuse of the triangle is the length of the wire.

let's use the smaller triangle to find the angle opposite the tower. Therefore,

tan ∅ = opposite / adjacent

tan ∅ =  5 / 2

∅ = tan⁻¹ 2.5

∅ = 68.1985905136

∅ = 68.20°

Therefore,

cos 68.20 = adjacent / hypotenuse

cos 68.20 = 33 / hypotenuse

hypotenuse = 33 / cos 68.20

hypotenuse = 88.8606843161

Therefore,

length of wire ≈ 89 feet.

ASAP PLZZZ The axis of symmetry for the graph of the function f start bracket x end bracket equals one-quarter x square plus b x
Lilit [14]

Answer:

b=-3

Step-by-step explanation:

The  given function is f(x)=\frac{1}{4}x^2+bx+10.

When we compare to ax^2+bx+=0, we have

a=\frac{1}{4} and c=10

The equation of the axis of symmetry of a vertical parabola is:

x=-\frac{b}{2a}

Also from the question the axis of symmetry is x=6

We substitute the values to get:

6=-\frac{b}{2*\frac{1}{4}}

6=-\frac{b}{\frac{1}{2}}

b=-\frac{1}{2}*6

b=-3

Sal and her three friends plan to bowl one or two games each. Each game costs $2.50 each. Identify the independent and dependent
tino4ka555 [31]
So the dependent is the number of games because it's not definite they dont know for sure. so the domain always involves money!!! always! the range wiyld be the numbers they migh play like 8-10 so 4 to 8 is the range value. so determining off of that the indepedent variable would be the total cost becuase it wont change so your answer is C hope this helped have a good day!!!
