Answer:

A. -4 ≤ x ≤ 9

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

We see that our x-values span from -4 to 9. Since both are closed dots, they are included in the domain:

[-4, 9] or -4 ≤ x ≤ 9

Step-by-step explanation:

you just divide meters by seconds. It helps to try and make the units match. since the unit is m/s you know to divide the meter by the seconds.\

Answer:

neither

Step-by-step explanation:

using (y2-y1)/(x2-x1) you get the actual slopes which are JK = 3/2 and LM = -3/2

since they are neither the same (parallel), opposite reciprocals (perpendicular), they are neither parallel nor perpendicular

Answer:

A. f(x) = −4sin(x)

Step-by-step explanation:

The graph that meets the origin and goes down is option A, f(x)=-4sin(x). This is because the sine function oscillates between 1 and -1, and the negative sign in front of the sine function flips the graph upside down. So, the graph starts at the origin at a value of 0, then oscillates down to a minimum value of -4, then oscillates back up to a maximum value of 4, and so on.

Step-by-step explanation:

The polynomial is of degree 3, so will have a maximum of ...

Because the degree is odd the signs of the end values of h(x) will be different. Because the leading coefficient is positive, the signs of the end values of h(x) will match the sign of x:

Answer:

The nearest whole is 6.

Step-by-step explanation:

We are going to round each number.

We know the rule if it is under 5, we do not make the number change. If it is above 5, the number changes. For this one, we do not have to round the hundredths or thousandths. We do round the 8, though. The nearest whole to 5.8 is 6, since 8 is above 5 and that means it is closer to 6 rather than 5.

The amount invested at 3% is $400, the amount invested at 4% is $700, and the amount invested at 5% is $1000.

Let's assume the amount invested at 4% is x dollars.

According to the given information, the amount invested at 5% is $1000 more than the amount invested at 4%.

So, the amount invested at 5% is (x + $1000).

The total amount invested is the sum of the amounts invested at each rate, which is $2100.

Therefore, we can write the equation:

x + (x + $1000) + (amount invested at 3%) = $2100

Now, we can calculate the amount invested at 3%.

We subtract the sum of the amounts invested at 4% and 5% from the total investment:

(amount invested at 3%) = $2100 - (x + x + $1000) = $2100 - (2x + $1000)

Given that Elena receives $95 per year in simple interest from the investments, we can use the formula for simple interest:

Simple Interest = Principal × Interest Rate

The interest earned from the investment at 3% is (amount invested at 3%) × 0.03, the interest earned from the investment at 4% is (amount invested at 4%) × 0.04, and the interest earned from the investment at 5% is (amount invested at 5%) × 0.05.

According to the problem, the total interest earned is $95.

So we can write the equation:

(amount invested at 3%) × 0.03 + (amount invested at 4%) × 0.04 + (amount invested at 5%) × 0.05 = $95

Now we can substitute the expression for (amount invested at 3%) and solve for x.

Once we have the value of x, we can calculate the amounts invested at 3%, 4%, and 5% using the given information.

#SPJ8

Answer: 1.25%

Step-by-step explanation:

Given: A movie with an aspect ratio of 1.8:1  shown as a letter-boxed image.

Since a for l:b , Area = l x b

Area of letter box = 1.8 x 1 = 1.8 sq. units

Screen's ratio= 16:9

Area of screen = 16 x 9 = 144 sq. units

The percent of the screen's area that is occupied by the  image =[tex]\dfrac{1.8}{144}\times100=1.25\%[/tex]

Hence, the percent of the screen's area that is occupied by the

image. =1.25%

Answer:

All numbers can be written as a product of the prime numbers that conform them.

A) Find two numbers with a common factor of 3 only.

for example:

2*3 = 6

7*3 = 21

Both numbers have the factor 3 in them, and because the other two numbers are primes, we can be sure that the 3 is the only common factor.

B) Write a pair of numbers with a common factor of 2, 3 and  6.

Here we can write:

2*3*2 = 12

3*2*5 = 30

Those two numbers have the common factors 6, 2 and 3.

C) Write a pair of numbers with common factors of 3, 6 and  9.​

3*2*3 = 18 (has the factors 2, 3, 3*2 = 6, 3*3 = 9)

-3*2*6 = -36

Both have the common factors 3, 6 and 9 (and they share more common factors like 2, this happens because 6 = 3*2, so if 6 is a common factor, 2 also must be)

1.2% is basically 0.012. 12% is 0.12 and then 1.02 and 1.2. what i'm trying to get at here is when you are working with percents, 100% is 1. so anything below that is going to be a decimal, for an example, 34% would be 0.34, and 68% would be 0.68. Also 0.18% would be 0.0018. Once you know how to convert percentages to decimals, doing those kind of questions is pretty easy.

The matrix Transformation for ΔFGH, which has coordinates F(0, −1),G(5, −1), and H(4, 3), for a dilation by a factor of 1/4 is:\begin{pmatrix}x'\\y'\end{pmatrix}=\begin{pmatrix}1/4 & 0\\0 & 1/4\end{pmatrix}\begin{pmatrix}x\\y\end{pmatrix}.

A dilation is a type of matrix transformation that changes the size of a geometric figure, but not its shape, by multiplying all its coordinates by a constant factor.

To identify the matrix transformation of ΔFGH, which has coordinates F(0, −1),G(5, −1), and H(4, 3),

for a dilation by a factor of 1/4, we will first find the center of a dilation using the formula:

(x,y)\rightarrow (\frac{1}{4}x,\frac{1}{4}y)

Since this is a dilation with a center of origin, the center of dilation is (0, 0).

Next, we will find the image of each vertex by multiplying its coordinates by the dilation factor:

F(0, -1) becomes (0, -1/4)G(5, -1) becomes (5/4, -1/4)H(4, 3) becomes (1, 3/4)

Therefore, the vertices of the image are F’(0, -1/4), G’(5/4, -1/4), and H’(1, 3/4).

The matrix transformation for the dilation by a factor of 1/4 is:

\begin{pmatrix}x'\\y'\end{pmatrix}=\begin{pmatrix}1/4 & 0\\0 & 1/4\end{pmatrix}\begin{pmatrix}x\\y\end{pmatrix}

So, the matrix transformation for ΔFGH, which has coordinates F(0, −1),G(5, −1), and H(4, 3), for a dilation by a factor of 1/4 is:\begin{pmatrix}x'\\y'\end{pmatrix}=\begin{pmatrix}1/4 & 0\\0 & 1/4\end{pmatrix}\begin{pmatrix}x\\y\end{pmatrix}.

Answer:

B: x+2=8

Step-by-step explanation:

The output value of f( -23 ) in the function f( x ) = 3x² - 2x + 1 is 1634.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

To determine the output value of f( -23 ), replace all the occurrence of x with -23 in the function and simplify.

f( x ) = 3x² - 2x + 1

f( -23 ) = 3( 529 ) + 46 + 1

f( -23 ) = 1587 + 46 + 1

Add the numbers

f( -23 ) = 1587 + 47

f( -23 ) = 1634

Therefore, the output value of f( -23 ) is 1634.

Answer:

As a member, Tom's cost would be cheaper if he rents the courts 17 or more times.

Step-by-step explanation:

Let the number of times be x

If Tom is a member, and rents the courts x number of times, then he would pay

$135 + $3 × x = $135 + $3x

For a nonmember that rents x number of times, the nonmember would pay

$11 × x = $11x

Now, we are to determine which value of x for which $135 + $3x is less than $11x, that is

$135 + $3x < $11x

Solving the inequality,

$135 < $11x - $3x

$135 < $8x

$135 / $8 < x

16.875 < x

∴ x > 16.875

This means, for Tom's cost to be cheaper, he must have rented the court for more than 16.875 times. (Round 16.875 to the nearest whole number)

16.875 ≅ 17

∴ x > 17

Hence, As a member, Tom's cost would be cheaper if he rents the courts 17 or more times.
