The cost of renting a bike at Centre Island in Toronto is represented by the equation C = 2n + 10, where C is the cost of renting a bike and n is the number of hours of bike rental. [A4]

a) How long did you rent the bike for if the cost is $30? ✓✓

b) Rearrange C = 2n + 10 to isolate n. ✓✓

Answers

Answer 1

Answer:

A) 10

B) (C+10)/2 = n

Step-by-step explanation:

A) We know that the total cost is represented by the variable C. So, basically the problem is saying that the variable C is equal to 30. If we plug that into the equation, we get 30 = 2n + 10. Solving this, we get n = 10.

B) Isolating a variable means to only have the specified variable on one side and have all other integers and variable on the other side. So, the final answer would be (C+10)/2 = n.

Answer 2

C=2n+10
C- cost
n- number of hrs
C=30$
n=?
2n+10=30
2n=30-10
2n=20
n=20/2
n=10 hrs

You rented the bike for 10 hrs.

Answers

The function is not linear because the slope is not constant. I am pretty sure that it is an exponential function, since the line approaches 0 but never touches it, and it grows exponentially. The exponential parent function is f(x)=b^x.

Answer: b =50°

Step-by-step explanation:

The angles on a straight line =180°

180° = 50°+90°+b

180°-50°-90°=b

50° = b

Answer:

Step-by-step explanation:

∠b + ∠a + 50° = 180°

∠b + ∠90 + 50° = 180°

∠b = 180° - 90° - 50° = 40°

Answers

Answer:

x=47

Step-by-step explanation:

180-121=59

180-(59+74)=47

Answer:

x = 47

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

121° is an exterior angle of the triangle, then

x + 74 = 121 ( subtract 74 from both sides )

x = 47

Answers

Answer:

Step-by-step explanation:

Ratio = 3 : 2

Length =3x

Width = 2x

Perimeter = 50 inches

2*(length + width ) = 50

2* (3x + 2x ) = 50

2* 5x = 50

10x = 50

x = 50/10

x = 5

Length = 3*5 = 15 inches

c) Angles X and Z are supplementary, and sin X= 1 - cos Z

d) Angles X and Z are complementary, and sin X= 1 - cos Z

Step-by-step explanation:

The angles of X and Z are supplementary and sinX and cosZ will be the same hence, option (b) will be correct.

What is a trigonometric function?

The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.

The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.

The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.

The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.

Given that in triangle Y is 90° since in any triangle sum of all three angles will be 180° so remaining angle Z and Y will be total of 90° hence these will be complementary.

In right angle triangle sinX = cosZ because the perpendicular for X act like a base for Y.

Answer:

y - x + 8 = 0

Step-by-step explanation:

divide all sides by 4

y = x - 8

Slope intercept form looks like this: y = mx + b where m is the slope and b is the y intercept. An example of a line in slope intercept form is y = 5x + 3.

The important thing to realize is that y is alone on one side. It doesn’t have a coefficient (number in front of variable) and is positive. X and the constant (in the example above the constant is 3) are on the other side of the equation.

To put 4y - 4x = -32 into slope intercept form, first add 4x to both sides

4y = 4x - 32

Divide each side by 4 (so y is alone)

y = x - 8

You guys are Smart, Answer me this. But I need It fast-

Answers

Answer:

E = 58

F = 32

G = 90

Step-by-step explanation:

3x + 31 + 5x -13 + 90 = 180

3x + 31 + 5x -13 = 90

8x = 90 - 31 + 13

8x = 72

x = 72 / 8

x = 9

E = 3(9) + 31 = 27+31 = 58

F = 5(9)-13 = 45 - 13 = 32

G = 90

Answers

the angles you have to find are vertical angles to the equations that are given. a vertical angle is an angle that is directly across from another.

angle 1 is equal to 4x+10

angle 2 is equal to 8x-25

since this is a transversal,

4x+10=8x-25

then just solve for x.

x= 8.75

then substitute 8.75 wherever you see x.

4(8.75)+10 = 45
8(8.75)-25= 45

going back to the vertical angle rule, both angle 1 and 2 are equal to 45°
