Can you help me please!

Answer:

Step-by-step explanation:

From the graphs attached,

Let the coordinates of the two points given on the black line in the first graph are (-4, 2) and (-1, 10).

When these points have been rotated by 90° about the origin,

Rule for the rotation will be,

(x, y) → (y, -x)

Therefore, coordinates of the image points will be,

(-4, 2) → (2, 4)

(-1, 10) → (10, 1)

Therefore, red line given given in graph (1) and black line (After rotaion of 90° clockwise) in graph (2) will be same.

Answer:

yes they are the SAME.

Step-by-step explanation:

He'll buy 16 new releases and 22 classic movies.

Let x = number of new releases

Let y = number of classics.

The equation to solve the question will be:

20x + 8y = 500

When x= 16 and y = 22, thus will be:

= 20x + 8y

= 20(16) + 8(22)

= 320 + 176

= 496

Therefore, since this is the number closest to $500, therefore this will be the appropriate number of movies that he can buy.

In conclusion, he'll buy 16 new releases and 22 classic movies.

Answer:

  8

Step-by-step explanation:

Let x represent the number. Then the reciprocal is 1/x. The quotient of 25 and the number is 25/x. The problem statement tells us ...

  3 + 1/x = 25/x

Subtracting 1/x, we have ...

  3 = 24/x

  x = 24/3 = 8 . . . . . . . . multiply by x/3

The number is 8.

Answer:

Answer:

There are 20 cupcakes covered with sprinkles.

Step-by-step explanation:

To find the amount of cupcakes that are covered with sprinkles you would have to subtract the amount of cupcakes covered with peanuts, the ones covered with chocolate chips and the ones covered with coconut from the total amount of cupcakes:

Total amount of cupcakes=120

cupcakes covered with peanuts=1/5*120=24

cupcakes covered with chocolate chips=1/3*120=40

cupcakes covered with coconut=36

Now, you can subtract the different cupcakes from the total amount to find the quantity left that would be the ones covered with sprinkles:

cupcakes covered with sprinkles=120-24-40-36

cupcakes covered with sprinkles=20

According to this, the answer is that there are 20 cupcakes covered with sprinkles.

Answer:

[tex]M(h) = 7.50h + 50[/tex]

Step-by-step explanation:

Let's first get our variables straight. M is how much money you make each night, and h is the amount of hours she works.

This means that M will be what our function is equal to, aka the y-axis. h will be the x-axis.

We know that you earn a  rate of $50 per night through tax, and your hours worked doesn't influence this in any way. That means there will be a constant on this function, +50.

We also know that you earn 7.50$ per hour, which is directly influenced by how many hours you work, so we will have [tex]7.50h[/tex].

Combining this all together, we get

[tex]M(h) = 7.50h + 50[/tex].

Answer:

R2 > R1

Step-by-step explanation:

Here in this question, we want to select which of the relations best gives the answer.

Mathematically;

Power = Voltage * current

But current = voltage/resistance

Power = voltage * voltage/resistance

P = V^2/R

For 40 W

40 = (220)^2 * R1

R1 = 40/(220)^2

For 60 W

60 = (220)^2 * R2

R2 = 60/(220)^2

Mathematically, since we have the same denominator (220)^2 but with 60 greater than 40, that automatically translates to the fact that the value of R2 is greater than the value of R1( You can finish evaluating each of the expressions using a calculator).

Answer:

the domain represents all the x values and range represents all the y value

In a function y=mx+b ( linear equation), the problem is giving the y values so plug in the value of each (y) in the equation to get x.

example: the range is : { 2,4,6} find the domain in the function y=x+1

y=x+1  take value 2

2=x+1

this goes for linear equation

x=15-657/2=15-373/2=-5.316

x=15+657/2=15+373=20.316

Answer:

Ok, here we have the sequence:

0.25, 1.75, 3.75, 5.75, 7.75, …

First let's define the two most common types of sequences:

Arithmetic: The difference between any two consecutive terms of the sequence is always the same.

Geometric: In this case, the terms are created by multiplicating the previous term by a constant number (and this is for all the terms in the sequence).

Now let's try to see if this is arithmetic, to do it, we select different sets of two consecutive terms and see their difference, if all the differences are the same, then this is an arithmetic sequence:

1.75 - 0.25 = 1.5

3.75 - 1.75 = 2

5.75 - 3.75 = 2

So for the first two terms, the difference is 1.5 and for all the next ones, the difference is 2, then it is not an arithmetic sequence.

(it would be if the first term was -0.25 instead of 0.25).

Now let's try with geometric.

To see if the series is geometric, we should see the quotient of consecutive pairs of numbers, if this quotient is the same for all of them, then this is a geometric sequence:

1.75/0.25 = 7

3.75/1.75 = 2.14

Well, we can see that the quotients are different, then this can not be a geometric sequence.

Then the answer will be neither.

If we want to write a recursive rule will be like an arithmetic sequence, but with the first two terms specified as:

a₀ = 0.25

a₁ = 1.75

aₙ = aₙ₋₁ + 2 for n = 2, 3, 4, .......

Answer:

symmetry with respect to the y-axis

Step-by-step explanation:

f(x) = |x| has symmetry with respect to the y-axis. It looks like a V with the vertex at the origin.

The symmetry of the function [tex]f(x)=|x|[/tex] is represented by the y-axis.

The given function is [tex]f(x)=|x|[/tex].

The function can be defined as,

[tex]f(x)=x;\;\;x\geq0\\f(x)=-x;\;\;x<0[/tex]

The function will always give the positive value of y or f(x) for all values of x.

The graph of the function is in the shape of V which is symmetric about the y-axis.

See the attached image.

Therefore, the symmetry of the function [tex]f(x)=|x|[/tex] is represented by the y-axis.

Answer:

only q or r can be irrational

Step-by-step explanation:

Rational numbers are numbers that can be expressed in the form a/b, where both a and b are integers and b ≠ 0. The decimal representation of an rational  numbers either repeats the sequence of digits over again or terminates at a finite number.

Irrational numbers are numbers that are not rational. The decimal representation of an irrational  number does not repeat a sequence of digits over again and never terminates. e.g √2, π.

The product of two irrational numbers is a rational number, the product of two rational numbers is a rational number while the product of a rational and irrational number is an irrational number. Hence since in p*q*r is an irrational number and p is a rational number, If both q and r are irrational then:

q*r = irrational * irrational = rational

p*(q*r) = rational * rational = rational. Since the result is not an irrational number then both q and r cannot be irrational.

But, If either q and r are irrational then:

q*r = irrational * rational = rational * irrational = irrational

p*(q*r) = rational * irrational = irrational. Since the result is an irrational number then only q or r can be irrational

Answer:

1) Both q and r may be rational

2) r may be rational if q is irrational

Answer:

The number of softballs that would fill the room is 221796 softballs

Step-by-step explanation:

First we will determine the Volume of the room.

The volume of a room is given by

[tex]Volume = lwh[/tex]

From the question, the given dimension of the room is  10 by 12 by 24 foot

Hence the volume of the room = 10 × 12 × 24

= 2880 cubic feet (ft³)

Convert to cubic inches

To do this, multiply the answer in cubic feet by (12 × 12 × 12)

(NOTE: 1 foot = 12 inches)

Hence, 2880 cubic feet = 2880 × 12 × 12 × 12 cubic inches

= 4976640 cubic inches

This is the volume of the room.

To estimate the number of softballs that would fill the room, we will determine the number of softballs which would give a total volume that is equal to the volume of the room.

First, we will find the volume of one softball

Diameter of softball = 3.5 inches

∴ Radius of softball, r = 3.5/2 inches = 1.75 inches

∴ r = 1.75 inches

Now, for the volume of one softball

From,

V = 4/3 (3.14)r^3

[tex]V = \frac{4}{3}(3.14)r^{3}[/tex]

[tex]V = \frac{4}{3}(3.14)[/tex] × [tex]1.75^{3}[/tex]

[tex]V = 22.43791667[/tex] cubic inches

This is the volume of one softball

The number of softballs that would fill the room will be

= Volume of the room / Volume of one softball

= 4976640 cubic inches / 22.43791667 cubic inches

=221795.9926

≅221796

Hence, the number of softballs that would fill the room is 221796 softballs

Step-by-step explanation:

General equation for directly proportional variables: y = kx, where k is a real constant

When x = 8, y = 26.

Hence y = 26/8 x or y = 13/4 x.

The equation will be ; y = [tex]\frac{26}{8}[/tex] × x .

It is given that y varies directly with x and y = 26 when x = 8.

We have to find out an equation that represents this relationship.

What will be the 8 times of a number x ?

The number will 8 x.

The direct variation relationship equation will be ;

y = k × x

where ; k = a constant

Given ;

at x = 8 ; y = 26

so the value of k = 26 / 8

and the required equation will be ;

y = ([tex]\frac{26}{8}[/tex]) × x

Thus , the equation will be ; y = [tex]\frac{26}{8}[/tex] × x .
