Step-by-step explanation:

t = 20n + 15

t = 80

80 = 20n + 15

65 = 20n

n = 65/20 = 13/4 = 3.25 hours

The time it will take the ride to reach the floor is  77.29 seconds

These are equations that has a leading  degree of 2.

Given the function that represents the height of the roller coaster

h(t) = –0.086t^2 + 6t + 50,

At the ground level, h = 0

Substitute

h(t) = –0.086t^2 + 6t + 50,

–0.086t^2 + 6t + 50 = 0

0.086t^2 - 6t - 50 = 0

Answer:

D)  t = 77.29 seconds

Step-by-step explanation:

The height of the rollercoaster at ground level is zero.

Therefore, to find how long it will take riders to pass over the hill and reach ground level, set h = 0 and solve for t.

Set the equation equal to zero:

[tex]-0.086t^2 + 6t + 50=0[/tex]

Solve the equation using the quadratic formula.  

The quadratic formula is a formula that can be used to find the solutions of any quadratic equation, which is an equation of the form ax²+bx+c=0, where a, b, and c are constants and x is the variable.

[tex]\boxed{x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}}[/tex]

In this case:

Substitute these values into the quadratic formula and solve for t:

[tex]t=\dfrac{-6 \pm \sqrt{6^2-4(-0.086)(50)}}{2(-0.086)}[/tex]

[tex]t=\dfrac{-6 \pm \sqrt{36+17.2}}{-0.172}[/tex]

[tex]t=\dfrac{6 \pm \sqrt{53.2}}{0.172}[/tex]

[tex]t=-7.52228495..., \;\; 77.2897268...[/tex]

As time is positive only, t = 77.29 seconds (2 decimal places).

Answer:

m<A = 120

m<BCD = 120

m<DEC = 30

m<BFE = 90

Step-by-step explanation:

m<A is 120 cause all internal angles equal 720 added together in hexagons. 720 ÷ 6 = 120

m<BCD is 120 cause regular hexagons have eqaul angles

m<DEC is 0 cause total of the angle of triangle of triangle EDC is 180 where m<D = 120 which leaves m<E + m<C = 60 since they are equal we can combine them to m<E • 2 = 60. Divide and we get 30

m<BFE =  90 cause m<AFB = 30 and m<AFE = 120 subtract 120 and 30 to get 90

Point D would be translated to the point (0, 5).

Translation is an aspect of geometry that moves plane shapes from one point to another along the cartesian coordinates without changing the form in which the shape exists.

Analysis:

Point D is at (0,0) if it is translated up from 0,0 the point D moves 5 units along the y-axis while x axis remain same. So that the new point of D becomes (0,5)

In conclusion, the point D will land at point (0,5)

The translation of line AB to line A'B' is valid and the translation rule is (x,y) ⇒ (x - 7, y - 3)

The graph that completes the question is added as an attachment

From the graph, we have:

A = (3,9) and B = (5,6)

A' = (-4,6) and B' = (-2,3)

Subtract the x and y coordinates of A' from A and B' from B.

So, we have:

AA' = (3 + 4, 9 - 6)

AA' = (7, 3)

BB' = (5 + 2, 6 - 3)

BB' = (7, 3)

See that:

AA' = BB' = (7, 3)

This means that the line AB is translated 7 units left and 3 units down

The translation above means:

(x,y) ⇒ (x - 7, y - 3)

Recall that:

A = (3,9) and B = (5,6)

So, we have:

A' = (3 - 7, 9 - 3)

A' = (-4, 6)

Also, we have:

B' = (5 - 7, 6 - 3)

B' = (-2, 3)

Hence, the translation is valid

Answer:

a)  30 square units

b)  36 square units

c)  18 square units

Step-by-step explanation:

Area of a triangle = 1/2 × base × height

Base = 10

Height = 6

⇒ Area = 1/2 × base × height

            = 1/2 × 10 × 6

            = 30 units²

⇒ Area = 1/2 × base × height

            = 1/2 × 12 × 6

            = 36 units²

⇒ Area = 1/2 × base × height

            = 1/2 × 6 × 6

All else being equal, at a $1,333.33 balance, the two credit cards will offer the same deal (finance charge) over a year.

A credit card finance charge is the fee associated with using credit.

Credit card issuers use the finance charges to minimize non-payment risks and earn some profits for extending credit to cardholders.

                   Card A         Credit B

APR              22%               25%

Annual fee  $40                $0

To calculate the balance required, the required equation is

= 22%x + $40 = 25%x

Where x = required balance

Thus,

= 0.22x + $40 = 0.25x

= $40 = 0.03x (0.25x - 0.22x)

= 0.03x = $40

x = $40/0.03

x = $1,333.33

Credit card A has an APR of 22% and an annual fee of $40, while credit card B has an APR of 25% and no annual fee.

Thus, all else being equal, at a $1,333.33 balance, the two credit cards will offer the same deal over the course of a year.

Answer:

Step-by-step explanation:

The coefficient is the number in front of the variable

Answer:

Step-by-step explanation:

The coefficient in an expression is the multiplier of a designated part of a term of the expression.

__

The given expression is

  5z -2 +6x +3y

It consists of four (4) terms, added together. One term is a constant, -2. The others each have a single variable that is multiplied by a constant. When we ask for the coefficient of the variable, we are asking for the value of that constant multiplier.

The term containing x is 6x. The multiplier of x in that term is 6, so we say ...

  the coefficient of x is 6.

The term containing y is 3y. The multiplier of y in that term is 3, so we say ...

  the coefficient of y is 3.

The term containing z is 5z. The multiplier of z in that term is 5, so we say ...

  the coefficient of z is 5.

__

In an expression such as πr²h, different parts of the expression will have different coefficients. If we ask for the coefficient of the expression, we are generally asking for the constant: π. (The Greek letter pi is the symbol used to represent the irrational constant ratio between the circumference and diameter of a circle. Is is about 3.1415926535....)

If we ask for the coefficient of h, we are asking for the product (πr²) that multiplies h in this expression. Similarly, the coefficient of r² is (πh). Note that we have specified a "designated part" of the expression for which we want the coefficient. This is important when we are solving equations.

__

The commutative property of multiplication means that parts of a product can be written in any order. That is, 5·z is the same product as z·5. When the constant and variable parts of the expression can be unambiguously identified, the order does not matter. In some cases, a constant coefficient may come in several parts: 3z·5·2 has a z-coefficient of 30, for example.

See below for a case where there may be some ambiguity.

__

In the expression r², the constant 2 that comes after the variable, written as a superscript, is called an "exponent," not a coefficient. Often on Brainly, and sometimes in curriculum materials, you will see this written as r2, because superscripts do not get properly rendered. If you're writing this in plain text, the form r^2 is preferred.

Answer:

Step-by-step explanation:

Answer:

a) 1/5 bucket = 1 gallon

b) 8.4 buckets = 1 barrel

c) 5376 fl oz per barrel

Step-by-step explanation:

a) From the given information, 1 bucket = 5 gallons. This means 1/5 of a bucket is 1 gallon.

b) From the given information, 8.4 buckets = 1 barrel. This seems to be in the form that the question is asking for. If the question was asking how many barrels were in a bucket the answer would be 1/8.4 barrels = 1 bucket.

c) From the previously determined conversion factors, we can take ounces to barrels by converting barrels down to gallons.

1/8.4 barrels = 1 bucket; 1/5 bucket = 1 gallon; 1 gallon = 128 fluid ounces

We need to set up a series of fractions that use these factors:

[tex]\frac{128 fl oz}{1 gallon}*\frac{1 gallon}{1/5 buckets}*\frac{1 bucket}{1/8.4 barrels}[/tex]

These fractions can be simplified to [tex]\frac{128 fl oz}{1 gallon}*\frac{5 gallon}{1 bucket}*\frac{8.4 buckets}{1 barrel}[/tex]

Multiply the fractions: 5376 fl oz per barrel

(Note that the units cancel out in the fractions so that only fluid ounces per barrel are left.)
