Answer:

$70

Step-by-step explanation:

78-74=4

82-78=4

86-82=4

Luna earns $4 from doing 1 chore.

74-4=70, therefore Luna had $70 before doing chores.

I believe the answer would be $70 .

for each chore she earned $4 .. for doing one chore she then had $74 .. therefore before doing chores she had $70 .

hope this helps !

Evaluate the function below for x=3<br><br> f(x)=2x^3-x^2-4x+9
elixir [45]
Hello,

f(x)=2x^3-x^2-4x+9=(((0+2)x-1)x-4)x+9

f(3)=(((0+2)*3-1)*3-4)*3+9=((2*3-1)*3-4)-3+9=(5*3-4)*3+9=11*3+9=33+9=42

or

f(3)=2*3^3-3^2-4*3+9=2*27-9-12+9=54-12=42

Polygon ABCD is translated to create polygon A'B'C'D'. Point A is located at (1,5) os located at (-2,1). What is the distance fr
Sergio039 [100]

Answer:

The distance from B to B' is 5 units

Step-by-step explanation:

The complete question is

Polygon ABCD is translated to create polygon A'B'C'D'. Point A is located at (1,5) and point A' is located at (-2,1). What is the distance from B to B'?

we know that

In a translation the figure maintains its dimensions and internal angles

so

AA'=BB'=CC'=DD'

The distance BB' is the same that the distance AA'

<em>Find the distance AA'</em>

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

A(1,5),A'(-2,1)

substitute in the formula

AA'=\sqrt{(1-5)^{2}+(-2-1)^{2}}

AA'=\sqrt{(-4)^{2}+(-3)^{2}}

AA'=\sqrt{25}

AA'=5\ units

therefore

The distance from B to B' is 5 units

Solve the problem below
Sliva [168]

Answer:

T = 60 degrees

Step-by-step explanation:

The dotted line is the height so it is a right angle

We are able to use trig functions since this is a right triangle

cos T = adj side / hyp

cos T = a/b

cos T = 8 sqrt(2) / 16 sqrt(2)

cos T = 1/2

Taking the inverse of each side

cos^-1 ( cosT) = cos^-1 ( 1/2)

T = 60 degrees
