Answer:

The temperature six minutes after being turned on is 125°.

T(t)= 65° + t * 10°

Step-by-step explanation:

Linear Equations

Ellie sets the temperature of the oven to 65°. The oven will increase the temperature at 10° per minute after being turned on.

After the first minute, the temperature of the oven is

65° + 10° = 75°

After the second minute, the temperature is:

65° + 2*10° = 65° + 20° = 85°

The same pattern goes on after minute 6, where the temperature is:

65° + 6*10° = 65° + 60° = 125°

The temperature six minutes after being turned on is 125°.

The general formula can be deducted for any time t as:

T(t)= 65° + t * 10°

Answer:

$5,460

Step-by-step explanation:

Given that :

Loan taken = principal (p) = $10,000

Simple Interest rate (r) = 9.1% = 0.091

Interest owed at the end of 6 years = t

Simple interest = (principal * rate * time)

Interest owed = 10,000 * 0.091 * 6

Interest owed = 910 * 6

Interest owed = $5,460

Answer:

Graph J represents the function -2x-5y=-10

Step-by-step explanation

To find the answer you have to find the y and x-intercepts first. To find the x and y-intercept I came up with two equations; -5y=-10 and -2x=-10. I came up with these equations because I'm finding the intercepts, so I know I have to substitute x and y with 0 one at a time. To solve the first equation I just divided -5 from both sides and got y=2, so my first intercept is (0, 2). I solved the second equation by dividing -2 from both sides and got x=5 which means my second intercept is (5, 0). Now I graph the two points on a graph and connect the dots, which turns out to be graph J on your image.

Answer:

all whole numbers

all whole-number multiples of 125

Step-by-step explanation:

The domain and the range of a function is the set of input and output values of the function.

Let the number of tickets be x, and the revenue be y.

So, the revenue function will be:

[tex]\mathbf{y = 125x}[/tex]

The number of tickets cannot be less than 0.

So, the domain of the revenue function is:

[tex]\mathbf{Domain = [0,\infty)}[/tex]

The above means that, the domain is the set of all whole numbers

Similarly, the revenue cannot be less than 0.

So, the range of the revenue function is:

[tex]\mathbf{Range = [0,\infty)}[/tex]

The above means that, the range is also the set of all whole numbers (in multiples of 125)

Answer:

The secant of angle x; sec x = √17

Step-by-step explanation:

Here, given the tangent of an angle, we want to find the value of the secant

Mathematically;

sec^2 x = 1 + tan^2 x

This is from trigonometric identity

Thus;

sec x = √(1 + tan^2 x)

According to the question;

tan x = 4

So tan^2 x = 4^2 = 16

Thus;

sec x = √1 + 4^2

sec x = √17

Explanation:

10% of 200 is 20

20/30 = $.6666

Each parent gets $0.67 off.

$200/30 = $6.6666

$6.6666 ---> $6.67

6.67 - 0.67

Answer:

Each parent pays an amount of £6.

Step-by-step explanation:

Cost of the hall = £200

Discount for parents = 10%

Cost of the hall for parents

= 200 - 10% of 200

= 200 - 10/100 × 200

= 200 - 10 × 2

= 200 - 20

= £180

If 30 parents share the cost equally,

Each parent has to pay

180/30

= 18/3

Answer:

a) 840 different ways

b) 35 different choices of books

Step-by-step explanation:

We know that our literature class will read a total of 4 novels this year.

All novels chosen by class vote from a list of 7 possible books offered by the teacher.

Wherever we have an experiment [tex]''N''[/tex] which is formed by sub - experiments that can occurred in [tex]m_{1},m_{2},...,m_{n}[/tex] ways, the total number of ways in which the whole experiment [tex]''N''[/tex] can be developed is :

[tex]m_{1}[/tex] x [tex]m_{2}[/tex] x ... x [tex]m_{n}[/tex]

Then, for a) if it matters what order we read the books in, the total number of different ways could the course unfold is :

[tex](7).(6).(5).(4)=840[/tex] (I)

Because for the first book there are 7 different choices. Now, given that we choose the first book, we only have 6 different choices for the second one.

Continuing with the idea, we deduce the equation (I).

For item b) :

Wherever we have [tex]''n''[/tex] different objects and we want to find the ways that we can choose [tex]''r''[/tex] objects from that group, we need to use the combinatorial number.

We define the combinatorial number as :

[tex]nCr=\left(\begin{array}{c}n&r\end{array}\right)=\frac{n!}{r!(n-r)!}[/tex]

Then, if we apply this to the problem, the total different choices of books if we want 4 novels voting from a total of 7 possible books is :

[tex]7C4=\frac{7!}{4!(7-4)!}=35[/tex]

a) 840 different ways

b) 35 different choices of books

Answer:

Step-by-step explanation:

or

Step-by-step explanation:

has:

1) amplitude=|a|

2) phase shift=b

3) period=2pi/c

d) vertical shift=d

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

You are given the amplitude is 2. This means a could either be 2 or -2.

You are given phase shift is -1/8. This means b is -1/8.

You are given the period is pi. So we need to solve pi=2pi/c.

pi=2pi/c

Dividing both sides by pi gives:

1=2/c

Multiply both sides by c gives:

c=2

The vertical shift is -2 so d=-2.

The equation could either be:

y=2cos(2(x-(-1/8)))-2

or

y=-2cos(2(x-(-1/8)))-2

Simplifying a little gives:

y=2cos(2x+1/4)-2

y=-2cos(2x+1/4)-2

The set of ordered pairs represents a function because every input has only one corresponding output.

The first step is to recognize that the equation describes a vertical line in problem 3 and a horizontal line in problem 5. The perpendicular to a vertical line is a horizontal line, and vice versa.

__

3. To make the desired horizontal line go through the point (-8, -1) the y-value of the line must match that of the point:

  y = -1

Step-by-step explanation:

The zeroes of the polynomial are 1 + i, 1 – i, and 3. Then the polynomial of the lowest degree will be x³ – 5x² + 8x – 6.

A polynomial expression is an algebraic expression with variables and coefficients.

The zeroes of the polynomial will be 1 + i, 1 – i, and 3.

Then the factor of the polynomial will be (x – 1 – i), (x – 1 + i), and (x – 3).

Then the polynomial will be

(x – 1 – i)(x – 1 + i)(x – 3)

[(x – 1)² – i²](x – 3)

(x² – 2x + 2)(x – 3)

Answer:

The volume of water in the pool over time from when the hose is placed in the pool until the pool is full is defined by the equation  and its graph is given below.

Explanation:

The total capacity of the pool is 20,000 gallon.

It is given that the pool contains 5000 gallons of water when a hose is placed in the pool and begins adding water at a rate of 1250 gallons per hour. So the initial volume of water is 5000.

Let the time is defined by t. So, the volume of water in the pool after time t is defined as,

The capacity of the pool is 20,000 gallon, therefore the maximum value of V(t) is 20,000.

The maximum value of t is 12, since the time is always positive, therefore we can say that,

The below graph representing the volume of water in the pool over time from when the hose is placed in the pool until the pool is full. The initial point is (0,5000) and the other point is (12,20000).

Answer:

x=5

Step-by-step explanation:

I first subtracted 88 from 180 because we know that 180 is the total degree of the three angles in a trangle. I got 92, then divided that by 2 since there are two angles that are unknown. I got 46, which I can then use to form the equation (9x+1)=46. I subtracted 1 from both sides to get rid of the 1 (since we're finding what x equals to), I then got 9x=45. After that, I divided 9 from both sides and got the answer x=5.
