One angle of a right triangle measures 78°. What is the measure of the other acute angle?

Answers

Answer:

12°

Step-by-step explanation:

a right triangle implies there is an angle that is 90°

another angle is 78°

the third angle is 180 - (90 + 78) = 180 - 168 = 12°

Evaluate f(x)= -6+12 when x= -3,x=0, and x=1.
When x= -3, f(x)= , when x=0,f(x)= , and when x=1,f(x)= .

Answers

Given :

A function, f(x) = -6 + 12

To Find :

The value of f(x) when x= -3, x= 0 and x=1.

Solution :

Given function is f(x) = -6 + 12 .

Simplifying above function, we get :

f(x) = 6

Now, the given function is independent of x.

So, for any value of x the the value of functions remains constant.

Hence, this is the required solution.

Answers

Answer:

28.1x – 3.1

Step-by-step explanation:

1.5(x + 3) + 3.8(7x –2)

Open the parenthesis

= 1.5x + 4.5 + 26.6x - 7.6

Simplify

= 28.1x - 3.1

Therefore, the equivalent expression to 1.5(x + 3) + 3.8(7x –2 is 28.1x - 3.1

Drag the tiles to the boxes to form correct pairs.

Match each pair of lines to the correct description

parallel lines
EF and CD
perpendicular lines
GH and EF
neither parallel nor
perpendicular lines
AB and CD

Answers

When two lines intersect at 90° degrees angle, the lines are perpendicular to each other. Two perpendicular lines, their slope will give a product of -1

i.e. if the first's line slope is 5, then the second line's will be -1 ÷ 5 = -¹/₅

To find the slope of a line, we divide the vertical distance by the horizontal distance.

We'll use the trial and error method to find the right pairing

Let's start with A(3, 3) and B(12, 6)

Vertical distance =

Horizontal distance =

The slope AB = ³/₉ = ¹/₃

We want BC to have a slope -1 ÷ ¹/₃ = -3

Try C(16, -6); check the slope with B(12, 6)

Vertical distance =

Horizontal distance =

Slope of BC = -12 ÷ 4 = -3

The slope BC = -3 is the value we want so, tile 1 pair with tile 4

-------------------------------------------------------------------------------------------------------------

Let's do A(-10, 5) and B(12, 16)

Vertical distance = 16 - 5 = 11

Horizontal distance = 12 - -10 = 22

Slope AB = ¹¹/₂₂ = ¹/₂

The perpendicular slope would be -1 ÷ ¹/₂ = -2

Try C(18, 4) with B(12, 16)

Vertical distance = 16 - 4 = 12

Horizontal distance = 12 - 18 = -6

Slope BC = ¹²/₋₆ = -2

Slope BC and slope AB perpendicular, so tile 3 matches with tile 6

--------------------------------------------------------------------------------------------------------------

Let's try A(12, -14) and B(-16, 21)

Vertical distance = 21 - -14 = 35

Horizontal distance = -16 - 12 = -28

The slope AB = ³⁵/-₂₈ = ⁵/₋₄

We need the perpendicular slope to be -1 ÷ -⁵/₄ = ⁴/₅

Try C(-11, 25)

Vertical distance with B = 25 - 21 = 4

Horizontal distance with B = -11 - -16 = 5

The slope = ⁴/₅

Tile 7 matches tile 8

--------------------------------------------------------------------------------------------------------------

Take A(-12, -19) and B(20, 45)

Vertical distance = 45 - -19 = 64

Horizontal distance = 20 - -12 = 32

Slope AB = ⁶⁴/₃₂ = 2

We need the perpendicular slope to be -1 ÷ 2 = -¹/₂

We have C(6, 52) and checking the slope with B(20, 45)

Vertical distance = 45 - 52 = -7

Horizontal distance = 20 - 6 = 14

The slope is ⁻⁷/₁₄ = -¹/₂

Tile 9 pairs with tile 2

-----------------------------------------------------------------------------------------------------------

Conclusion

Tile 1 ⇒ Tile 4

Tile 3 ⇒ Tile 6

Tile 7 ⇒ Tile 8

Tile 9 ⇒ Tile 2

Tile 5 and Tile 10 do not have pairs

Answer:

Parallel lines = AB and CD

Neither parallel nor perpendicular lines = GH and EF

Perpendicular lines = EF and CD

Determine whether or not the following graph represents two quantities that are proportional to each other. Explain your reasoning.

Answers

Answer:

The quantities are not proportional.

Step-by-step explanation:

The values, x and y, do not begin or pass through the origin, (0,0). This means they are not proportional.

The graph represents two quantities are not proportional to each other.

What is Proportional?

A relationship is proportional if each pair of data values are related in the same way, by multiplying by a factor. You can recognize a proportional relationship by looking at data, an equation, or a graph.

Given:

As, A relationship is proportionate if its graph is a line or ray that passes through the origin.

and, It is not proportionate if the line or ray does not go through the origin. Additionally, if anything is not linear, it is not proportional.

Here the graph also does not pass through the origin.

Hence, the graph is not proportional.

An ice hockey puck is in the shape of a cylinder with a radius of 3.8 cm, and a thickness of 2.5 cm.

It is made out of rubber with a density of 1.5 grams per cm ³

Work out the mass of the ice hockey puck.

Give your answer correct to 3 significant figures.

Answers

The mass of the ice hockey puck with the below dimensions and density of 1.5 g/cm² is 170 grams.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.

The volume of the puck = π * radius² * thickness = π * 3.8² * 2.5 = 113.4115 cm³

Density = mass / volume

1.5 = mass / 113.4115

mass = 170 g

The mass of the ice hockey puck with the below dimensions and density of 1.5 g/cm² is 170 grams.
