Answer:

1 = 88 2 = 42 3 = 113

Step-by-step explanation:

2 is 42 because it is the opposite angle and then you subtract 42 and 50 from 180 to get 88 for #1 and you subtract 42 and 25 from 180 to get 113 for #3.

Answer:

The two sides we know are O pposite (300) and A djacent (400).

SOHCAH TOA tells us we must use T angent.

Calculate Opposite/Adjacent = 300/400 = 0.75

Find the angle from your calculator using tan-1

Quadrilateral rust has a vertex (2,4). What are the coordinates of r' after a dilation of scale factor 3, centered at the origin

Digiron [165]

Answer:

The coordinates of r' are x = 10 and y = 12.

Step-by-step explanation:

The vertex experiments two operations: Dilation and translation, whose definitions are presented herein:

Dilation with respect to origin

$(x',y') = (0,0) + 3\cdot (x,y)$ , $\forall \,x,y \in \mathbb{R}$

Translation

$(x',y') =(x+4,y)$ , $\forall\,x,y\in \mathbb{R}$

If $x = 2$ and $y = 4$ , then:

1) $(2,4)$ Given.

2) $(0,0) + 3\cdot (2,4)$ Dilation with respect to origin.

3) $(6,12)$ Vectorial sum and scalar multiplication.

4) $(6+4,12)$ Translation.

5) $(10,12)$ Vectorial sum. Result.

The coordinates of r' are x = 10 and y = 12.

Each month Allison gets a $15 allowance and earns $100 working at the theater. She uses the expression 15x+100y to keep track of

Marizza181 [45]

Step-by-step explanation:

The expression for he earning of Allison and her allowance is as follows :

15x+100y

Part A

Variables are x and y. Coefficients are 15 and 100.

Part (B)

There are two terms in this expression. + is used to separate the terms. 15x and 100y are the terms.

Part (C) As $15 shows her earning from allowances. Hence, 15x shows allowance.

5.Find the slope of a line perpendicular to

Lemur [1.5K]

Hi there!

When the slopes of two perpendicular lines are multiplied the outcome will be -1.

The slope is the number that is positioned in front of the variable x in the formula. In this case the slope of the given line is -2/5.

Let's call the slope of the perpendicular line m and take into account the given data of the question and my earlier explanation. We then find the following:

$- \frac{2}{5} \times m = - 1$
Divide both sides by - 2/5.

$m = \frac{ - 1}{ - \frac{2}{5} } = 2 \frac{1}{2} = \frac{5}{2}$
The answer is B.

~ Hope this helps you!
