Answer:

According to me it is quadratic function.

Answer

The function [tex]f(x)=9x^2+4x-2[/tex] is a quadratic function.

Linear functions are the functions having the highest power as one, whereas the quadratic functions have two as the highest power. On the other hand, the function which has the form of [tex]f(x)=\text{e}^x[/tex] is known as an exponential function.

The function [tex]f(x)=9x^2+4x-2[/tex] has the highest power of [tex]2[/tex].

Thus, the function [tex]f(x)=9x^2+4x-2[/tex] is a quadratic function.

Given the data:

12, 15, 7, 14, 12, 3, 16, 15, 19, 20, 12, 9, 18, 21

Reordering the data:

3, 7, 9, 12, 12, 12, 14, 15, 15, 16, 18, 19, 20, 21

Mean = Σx / n = 193 / 14 = 13.76

The Median :

1/2(n+1)th term

15/2 = 7.5th term

(14 + 15) / 2 = 14.5

First quartile (Q1) :

1/4(n+1)th term

15/4 = 3.75th term

= 12

Q3 :

3/4(15)th term = 11.25 th term

Q3 = 18

Interquartile range = Q3 - Q1

Interquartile range = 18 - 12 = 6

Answer:

Reduction

Step-by-step explanation:

So, lets go over what we know:

The black rectnagle is the orginal shape.

The organe rectnalge is the new shape.

The organge rectangle is smaller than the black rectangle.

The rogane rectangle is a scaled image of the black rectangle.

So, enlargment is when a object has a scale factor that makes it bigger than the orgninal object.

Reduction, on the other hand, is when a object has a scale factor that makes it smaller than the orginal object.

As we can see, the organe rectnagle is much smaller than the black rectnalge.

So this must be reduction, since the organe rectangle has a small scale factor that causes the shape to shrink in size.

Hope this makes sense and helps you! :)

Answer:

Step-by-step explanation:

We have to find 6% of $450. We can make an expression and solve it:

6/100•450

We can cancel out factors now:

3/50•450

Now we'll cancel out 50 and 450:

3x9=$27

And that's your answer! Hope this helps =)

Given:

The table of values.

To find:

Whether the given relation in the table is proportional or non proportional.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

[tex]\dfrac{y}{x}=k[/tex]

Where, k is the constant of proportionality.

It means the ratio of y and x remains same for proportional relation.

From the given table, the points are (10,18), (11,18.6) and (12,19.2). The ratio of y to x for these points are:

[tex]\dfrac{18}{10}=1.8[/tex]

[tex]\dfrac{18.6}{11}\approx 1.69[/tex]

[tex]\dfrac{19.2}{12}=1.6[/tex]

Since the ratio of y to x for the given points are not equal, therefore the given relation is a non proportional relation.

Answer:

b=6

a=6

hypotenuse=6√ 2

Step-by-step explanation:

This is a 45, 45, 90 triangle. This means a=b and hypotenuse is equal to b times √ 2. This means that you have to divide the hypotenuse by √ 2 to get what b is equal to 6√ 2 divided by √ 2 is equal to 6. Therefore, b=6. Because b and a are equal, a is also equal to 6. Therefore, b=6, a=6.

Junk food because the TV gives you something to do.

Step-by-step explanation:

Have a great day :)

Answer:

Step-by-step explanation:

Apply the Pythagorean Theorem:

85^2 = 67^2 + h^2, where h is the height of the TV

Then 7225 = 4489 + h^2, or

h^2 = 2736, or h = +√2736 = 52.3 inches

The TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.

It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.

We have:

A certain television is advertised as a 85 inch TV

It means the diagonal length is 85 inches.

Width of the TV = 67 inches

Let's suppose the TV is x inches Tall

So from the Pythagoras theorem:

[tex]\rm 85^2 = x^2+67^2[/tex]

7225 = x² + 4489

x = 52.30 inches

Thus, the TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.

Answer:

Since the calculated value of z= -1.496 does not fall in the critical region z < -1.645 we conclude that the new program is effective. We fail to reject the null hypothesis .

Step-by-step explanation:

The sample proportion is p2= 7/27= 0.259

and q2= 0.74

The sample size = n= 27

The population proportion = p1= 0.4

q1= 0.6

We formulate the null and alternate hypotheses that the new program is effective

H0: p2> p1   vs  Ha: p2 ≤ p1

The test statistic is

z= p2- p1/√ p1q1/n

z= 0.259-0.4/ √0.4*0.6/27

z=  -0.141/0.09428

z= -1.496

The significance level ∝ is 0.05

The critical region for one tailed test is z ≤ ± 1.645

Since the calculated value of z= -1.496 does not fall in the critical region z < -1.645 we conclude that the new program is effective. We fail to reject the null hypothesis .
