A roller coaster at an amusement park rises to a height of 196 feet above the ground. So far, it has risen 36% of this height. To estimate the height the roller coaster has risen so far, Jake did the following.

1. Rounded 36% to 40%
2. Rounded 196 to 200
3. 10% of 200 is 20
4. 20 (4) = 80
5. 36% of 196 is about 80

However, Jake’s estimate was too high by almost 10 feet. Why was his estimate off by so much?

He made a computation error.

He rounded the percent up to 40% and the number up to 200.

He made a rounding error, and should have rounded 196 down to 100.

He should have rounded the percent down to 30% and the number down to 190.

Step-by-step explanation:

when perpendicular, u must use m1m2=-1

so , (⅓)(m2)=-1

m2= -3

y-y1=m2(x-x2)

y-1=-3(x-0)

y=-3x+1

Answer:

y = -3x + 1

Step-by-step explanation:

to be perpendicular the multiplication of the gradiens should be -1

m1 × m2 = -1 , m1 = 1/3

1/3 × m2 = -1

m2 = -3

and required equation passes through the point.( 0,1)

y = m2 x + c2

1 = -3 (0) + c2

c2 = 1

so the equation

y = -3x + 1

Answer:

x= -1

Step-by-step explanation:

2(x -5) -6 = -18

2x -10 -6 =-18

2x -10 -6 =-18

2x -16 = -18

2x =16 += -18

2x -16 +16 = -18 +16

2x = -2

2x/2 = -2/2

x=-1

x = -1

Answer:

2³

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , thus

[tex]2^{-2}[/tex]  × [tex]2^{5}[/tex] = [tex]2^{(-2+5)}[/tex] = 2³ [ = 8 ]

Answer:

5

Step-by-step explanation:

Input the given values of p and q into the expression and solve:

[tex]\frac{p+q}{3}[/tex]

[tex]\frac{9+6}{3}[/tex]

9 + 6 = 15

[tex]\frac{15}{3} = 5[/tex]

The value of the expression is 5.

Answer:

x=17

Step-by-step explanation:

7x+15=4x+66

3x=51

x=17

Answer:

17

Step-by-step explanation:

7x + 15° =  4x + 66° (vertically opposite angles are equal)

7x - 4x = 66 - 15

3x = 51

x = 51/3

x = 17

hope it helps you^^

Answer:

This function is a decay function and the rate of change is 0.16.

Step-by-step explanation:

We can tell this a decay function because the number in the parentheses is less than 1.

The "parent" function of a decay function is [tex]y = (1-b)^{x}[/tex], where x represents the t and b is the rate of change.

So that means 0.16 is b and 1 - 0.16 resulted in 0.84.

<P=(10(13)-4)=126

<Q=(4(13)-22)=30

<R=13+11=24

Answer:

P

Step-by-step explanation:

P tells us that the Domain: 3,-1,4,2 doesn't repeat

Q does repeat its Domain: 7,5,-1,5

Reminder that in order for a line of ordered pairs to be a function the domain number Shouldn't repeat, That doesn't mean that the range cant repeat.

Example: (5,-3), (5,9) Not a function

                (-1,-6), (7,-6) Function

Out of the two set given, the set of ordered pairs that represents a function is: P = {(3, 5), (−1, 5), (4, −6), (2, 9)}.

A set of ordered pairs that has one exact y-value assigned to each x-value is considered a function.

In set P, all x-values has exactly one y-value, while in set P, the x-value, 5, has two different y-values, 9 and -3.

Therefore, the set of ordered pairs that represents a function is: set P.

Answer:

Step-by-step explanation:

Considering the functions

[tex]f(x) = 5x + 4[/tex]

[tex]g(x) = x - 3[/tex]

Part 1)

Find

We need to first dertermine [tex]g(6)[/tex]

[tex]g(x) = x - 3[/tex]

Putting x = 6

[tex]g(6) = 6-3=3[/tex]

Then

[tex]f(g(6))=f(3)=5(3)+4=15+4=19[/tex]

Hence,

[tex]f(g(6))=19[/tex]

Part 2)

Find

We need to first dertermine [tex]f(-7)[/tex]

[tex]f(x) = 5x + 4[/tex]

Putting x = -7

[tex]f(-7) = 5(-7)+4=-35+4=-31[/tex]

Then

[tex]g(f(-7))=g(-31)=(-31-3)=-34[/tex]

Hence,

[tex]g(f(-7))=-34[/tex]

Part 3)

Find

We need to first dertermine [tex]f(8)[/tex]

Putting x = 8

[tex]f(8) = 5(8)+4=40+4=44[/tex]

Then

[tex]f(f(8))=f(44)=5(44)+4=220+4=224[/tex]

Hence,

[tex]f(f(8))=224[/tex]

Part 4)

Find

[tex]f(x) = 5x + 4[/tex]

[tex]g(f(x))=g(5x+4)[/tex]

         [tex]=(5x+4)-3=5x+1[/tex]

Hence,

[tex]g(f(x))=5x+1[/tex]
