Evan is thinking of a number that contains the digit 2. The digit 2 in Evan's number has 10 times the value of the digit 2 in the number 328,907.

Which number could be the number that Evan is thinking of?

Answer:

1.

  x = (2,0)

  y = (0,-8)

2.

   x  = (-2,0)

   y  = ( 0, 2)

3.

    x =  ( 4,0)

    y = ( 0, -16)

Step-by-step explanation:

aIll do one equation as an example

f(x) = 4x -8

y = 4x - 8

since its an intercept you know the x, for the y intercept will be zero and vice versa. Its like this cause its on the axis.

So you only need to figure out the y for the y intercept and the x for the x intercept.

- 4x  + y = -8

after changing the equation to standar form you then ignore the x base so, 4x to get the y intercept.

- 4x + y = -8 becomes  y = - 8 then you add the 0 for the coordinate

y = -8 becomes (0,-8)

f(x) = 4x -8

y = 4x - 8

- 4x  + y = -8

 y = - 8

(0,-8)

f(x) = 4x -8

y = 4x - 8

- 4x  + y = -8

-4x = -8

x = 2

(2, 0)

No, the inference is not valid because it excluded those who were not online and so did not see the poll.

To improve the poll, the news show could have conducted it in a more representative manner by surveying a larger sample of people from a variety of backgrounds

The poll's results may have been influenced by various factors, including but not limited to the order in which the comedians were presented, the demographics of the respondents, and the fact that it was conducted online, possibly excluding those without internet access. Overall, the poll's representative accuracy is questionable.

Answer:

A. The causal connection is valid. Students who spend more time and effort studying will be able to memorize more​ information, so their test grades will be higher.

Step-by-step Explanation:

The causal connection between the test grades of students and the amount of time and effort spent the students spend in studying and preparing for the test appears to be valid. This is valid because students who spend more time and effort studying would most likely be able to memorize more information of which they are most likely to come by in the test they take. Invariably, they'd be able to easily recall what they've memorize and give the right answers to the questions they are asked in the test, and this definitely will earn them higher test grades.

The distribution is bimodal (a), eight men weigh less than 150 lbs (b), and the percentage of males that weigh more than 230 lbs is 3.17%.

A: Distribution: The distribution can be classified as bimodal, which means there are two peaks in the graph.

B. The number of males that weigh less than 150 lbs can be determined as follows:

110 - 120 lbs = 2 males

130 -140 lbs = 2 males

140 - 150 lbs = 4 males

2 + 2 + 4 = 8 males

C. The percentage of males that weigh more than 230 lbs can be calculated as follows:

63 = 100%

2   = x

x= 2 x 100 / 63

x = 200 / 63 = 3.17%

Answer:

Step-by-step explanation:

the total surface area of such a pyramid is the sum of 5 areas :

1 bottom square (8×8)

4 side triangles

the area of a triangle is

baseline × height / 2

now, we know the baseline of the 4 triangles, but what is their height (at least we know, all 4 have the same height, as the pyramid is totally regular) ?

the height of the side triangles is the slant height of the pyramid (the distance from the middle of a sideline to the top of the pyramid).

we get this by imagining a right-angled triangle inside the pyramid :

one leg is the inner height of the pyramid.

the second leg is the connection on the bottom square from the base of the inner height to the middle point of a sideline). this is half the length of a sideline.

and the baseline (Hypotenuse) is the slant height of the pyramid.

we can use Pythagoras

c² = a² + b²

with c being the Hypotenuse (side opposite of the 90° angle).

slant height² = 7² + (8/2)² = 49 + 4² = 49 + 16 = 65

slant height = sqrt(65) = 8.062257748... in

so, we get a areas

bottom square = 8×8 = 64 in²

a side triangle = 8×sqrt(65)/2 = 4×sqrt(65) =

= 32.24903099... in²

all 4 side triangles = 4×32.24903099... =

= 128.996124... in²

and we get as total surface area

64 + 128.996124... = 192.996124... in² ≈ 193.00 in²

Took the test

P=160-70*cos(2π*(1/12)*t)

• Pressure in mathematics or physics is defined as force per unit area. The pressure exerted by a solid object which is resting on top of a solid surface is the weight divided by the area of the object . SI unit of force is Newton (N).

First, we find the amplitude by taking the difference between the peak values and dividing by two:

Amplitude=(230+90)/2=70

We can find the center value by either adding 70 to the minimum or subtracting 70 from the maximum:

90+70=160

230-70=160

This tells us that the Center Value=160

The frequency that we are operating at is given as:

f = 5/hour

so in minutes

f=5*(1/60)/minute=5/60=1/12 per minute

Thus, the scale factor from circle A to circle B is found to be 2.

The ratio between comparable measurements of just an element and a portrayal of that element is known as a scale factor in mathematics. The copy will be larger if the scaling factor is a whole number. A fractional scaling factor means that the duplicate will be smaller.

You must first choose which direction we are scaling in order to determine the scale factor:

The radius of circle A = 2 units

The radius of circle B = 4 units.

So, there is a dilation with the scale factor of 2 units as 2*2 = 4 units.

Thus, the scale factor from circle A to circle B is found to be 2.

Answer:

A)

Function A: Exponential

Function B: Linear

Function C: Exponential

Function D: Exponential

B) Function A

Step-by-step explanation:

Function A: This is exponential because- (1, 3)(2,9)(3,27)

It is not going up by the same number each time. However, it is multiplying by 3 each time which means it is exponential.

Function B: This is linear because- (1, 64)(1, 80)(1, 96)

It is going up by 16 each time, (a constant number) which means it is linear.

Function C: This is exponential because- there is a curve, linear is always a straight line. But, this has a curve which means it is exponential.

Function D: This is exponential because- It is increasing by a percentage and not a constant number. It is increasing by 1% which means it is exponential.

The function that has the greatest growth factor is Function A because, Function A multiplies by 3 each time. Function B is linear, exponential functions always pass linear functions despite how "steep" they are. Eventually, the exponential function will surpass it. Function C is also exponential but is not as "steep" as Function A. Function A multiplies by 3 each time but Function C increases less. Function D is also exponential, and for the same reasons as Function C, Function A has the greatest growth factor.

The equation which would produce a parabola from the provided options are equation first and forth,

\(-5x^2 + 4x - 7y + 14 = 0\)

\(12x + 6y -5y^2 + 14 = 0\)

To of identify the type of conic section from an equation whether it is parabola, or not, let suppose the equation as,

\(Ax^2+By^2+Cx+Dy+E=0\)

If In this equation,

Either \(A=0\) or \(B=0\), but not both. Then it is the equation of parabola.

The first equation is,

\(-5x^2 + 4x - 7y + 14 = 0\)

There is no square term of y. Thus, this is the equation of parabola.

The second equation is,

\(-x^2 + 6x + y^2 - 8 = 0\)

This is not the equation of parabola, as there is two square terms of variable x and y.

The third equation is,

\(9x^2 - 12xy + 4y^2 + 4x - y + 5 = 0\)

Similar to the second equation, here is also two square terms of different variable. Thus, it is not a equation of parabola.              

The fourth equation is,

\(12x + 6y -5y^2 + 14 = 0\)

This equation is the equation of parabola, as there is only a single square term.

The fifth equation is,

\(20x^2 + 10xy - y^2 + 3x - 6y + 5 = 0\)

This is now the equation of parabola because of two square terms.

Hence, the equation which would produce a parabola from the provided options are equation first and forth,

\(-5x^2 + 4x - 7y + 14 = 0\)

Answer:

r = -10*cos(t)

Step-by-step explanation:

To write the rectangular equation in polar form we need to replace x and y by:

\(x=r*cos(t)\\y=r*sin(t)\)

Replacing on the original equation, we get:

\((x+5)^2+y^2=25\\x^2+10x+25+y^2=25\\(r*cos(t))^2+10*(r*cos(t))+25+(r*sin(t))^2=25\)

Using the identity \(sin^2(t)+cos^2(t)=1\) and solving for r, we get that the polar form of the equation is:

\((r*cos(t))^2+10*(r*cos(t))+25+(r*sin(t))^2=25\\r^2cos^2(t)+10rcos(t)+r^2sin^2(t)=0\\r^2cos^2(t)+r^2sin^2(t)=-10rcos(t)\\r^2(cos^2(t)+sin^2(t))=-10rcos(t)\\r^2=-10rcos(t)\\\\r=-10cos(t)\)

Step-by-step explanation:

the requied answer is 38.

according to the question the value of a=2,b=3,c=4.

here,

to find the value of   a³ + b (6 + c)we have to do it in steps:

first one is correct bro

The correct factorization of x³ - 27 is  (x - 3)(x² + 3x + 9).

a³ + b³ = (a + b)(a² -ab + b²) and a³ - b³ = (a - b)(a² + ab + b²).

If we know the formula of these two we can conclude by observing that

the second option x³ - 27 = (x - 3)(x² + 3x +9) is correct.

Answer:

Our three numbers are 8, 48, and 16.

Step-by-step explanation:

Let the first, second, and third numbers be x, y, and z, respectively.

The sum of them is 72. In other words:

\(x + y + z = 72\)

The second number y is three times the third number z. So:

\(y = 3z\)

And the third number z is eight more than the first number x. So:

\(z = x + 8\)

To find the numbers, solve for the system. We can substitute the last two equations into the first:

\(x + (3z) + ( x + 8) = 72\)

Substitute again:

\(\displaystyle x + 3(x+8) + x+8 = 72\)

Solve for x. Distribute:

\(x+3x+24+x+8=72\)

Combine like term:

\(5x + 32 = 72\)

Subtract:

\(5x = 40\)

And divide:

\(x=8\)

Thus, the first number is eight.

And since the third number is eight more than the first, the third number z is 16.

The second number is three times the third. Thus, the second number y is 3(16) or 48.

Our three numbers are 8, 48, and 16.
