Answer:

Amy is correct because a nonlinear association could increase along the whole data set, while being steeper in some parts than others. The scatterplot could be linear or nonlinear.

Step-by-step explanation:

Both linear and nonlinear associations could increase along the whole data set. That's why Joseph and the fourth option are incorrect.

Answer:

201.143 (approx.) cm²

area of circle = (pi)x(radius)^2

= 22/7 x (8)^2

=22/7 x 64

= 1408/7

= 201.142857143

= 201.143 cm^2 (approx.)

Answer:

the approximate area of circle is 201 cm²

D is the correct option.

Step-by-step explanation:

From, the given figure, the diameter of the circle is 16 cm.

The radius is half of the diameter.

Hence, the radius of circle is 16/2 = 8 cm

The area of a circle is given by

[tex]A=\pi r^2[/tex]

Substituting the value of r and π

[tex]A=3.14(8)^2\\\\A=200.96\\\\A\approx201[/tex]

Therefore, the approximate area of circle is 201 cm²

D is the correct option.

Ella can make 21 complete envelopes with her available red, white, and blue pages, since the number of complete sets is limited by the blue pages.

Ella has 48 red pages, 25 white pages, and 84 blue pages. She needs to put 2 red pages, 1 white page, and 4 blue pages in every envelope. To find out how many complete envelopes she can make, we need to calculate the number of complete sets of pages she can create based on the quantity of each color she has and the number she needs for each envelope.

For the red pages: 48 red pages / 2 pages per envelope = 24 envelopes

For the white pages: 25 white pages / 1 page per envelope = 25 envelopes

For the blue pages: 84 blue pages / 4 pages per envelope = 21 envelopes

Since the number of envelopes is limited by the color with the least amount of complete sets, Ella can make 21 complete envelopes because she will run out of blue pages after the 21st envelope.

Answer:

[tex]x^{4}[/tex]

Step-by-step explanation:

[tex]\frac{x^{5}y^{2}  }{xy^{2} }[/tex]

= [tex]x^{4}[/tex]

Question 1:

For this case we have the following expression:

[tex]\frac {x ^ 5y ^ 2} {xy ^ 2}[/tex]

We eliminate similar terms in the numerator and denominator:

[tex]\frac {x ^ 5} {x}[/tex]

By definition of division of powers of the same base we have to place the same base and subtract the exponents:

[tex]\frac {x ^ 5} {x} = x ^ {5-1} = x ^ 4[/tex]

ANswer:

Option D

Question 2:

For this case we must indicate which expression is not equal to 125.

We tested option A:

[tex]5 (\frac {5 ^ 3} {\frac {2} {5}}) ^ 2 =[/tex]

Simplifying we have:

[tex]5 (\frac {5 ^ 3 * 5} {2}) ^ 2 =\\5 (\frac {5 ^ 8} {4}) =\\\frac {5 ^ 9} {4}[/tex]

The expression is not equal to 125.

Answer:

[tex]y=\frac{1}{2}x-6[/tex]

Step-by-step explanation:

The general equation of a line: [tex]y = ax+b[/tex]

In our case a is given

[tex]a=\frac{1}{2}[/tex]

Now we plug in for a and we get:

[tex]y=\frac{1}{2}*x+b[/tex]

Now we plug in our coordinates into this equation and we solve for b

[tex]-3=\frac{1}{2}*6+b\\b = -6[/tex]

So the equation of the line is [tex]y=\frac{1}{2}x-6[/tex]

Answer:

[tex]y=\frac{1}{2}x-6[/tex]

Step-by-step explanation:

Since the Inclination of the line was already given to us. Let us use Inclination of line formula:

[tex]m=\frac{y-y_0}{x-x_0}[/tex]

Plugging it in those values then we have the equation of the line:

[tex]\frac{1}{2}=\frac{y+3}{x-6}[/tex]

Rewriting, multiplying both sides

2y+6=x-6

2y=x-12 Rearranging

[tex]y=\frac{1}{2}x-6[/tex]

Answer:

9a^2 +  3ab  - 6b^2

Step-by-step explanation:

(3a-2b)(3a+3b)

First term of each grouping is 3a and 3a.

Multiply those you get 9a^2.

Outer term of each grouping is 3a and 3b.

Multiply those you get 9ab.

Inner term of each grouping is -2b and 3a.

Multiply those you get -6ab.

Last term of each grouping is -2b and 3b.

Multiply those you get -6b^2.

Add up all your products from above.

9a^2+9ab+-6ab+-6b^2

There are like terms here.  The 9ab+-6ab which is 3ab.

This is called the transitive property.

It says something like:

If f is related to g and g is related to h, then f is related to h.

The parallel relationship is transitive.

That is,

if X is parallel to Y and Y is parallel to Z, then X is parallel to Z.

[tex]f(g(x)) =\sqrt{6x^2-1}[/tex]

Step-by-step explanation:

Given

f(x) = √2x-5

and

g(x) = 3x^2+2

We have to find the composition of both function

f(g(x)) means that we have to put function g in place of x in function f.

[tex]f(g(x))= \sqrt{2*g(x)-5}\\ =\sqrt{2(3x^2+2)-5}\\=\sqrt{6x^2+4-5}\\=\sqrt{6x^2-1}[/tex]

..

The composite function f(g(x)) is given by f(g(x)) = √(6x^2 - 1).

To find the composite function f(g(x)), you need to substitute the expression for g(x) into the function f(x). Here's how you can do it step by step:

Start with the function g(x):

g(x) = 3x^2 + 2

Now, substitute this expression into the function f(x):

f(g(x)) = √(2(3x^2 + 2) - 5)

Simplify the expression inside the square root:

f(g(x)) = √(6x^2 + 4 - 5)

Further simplify the expression inside the square root:

f(g(x)) = √(6x^2 - 1)

So, the composite function f(g(x)) is given by:

f(g(x)) = √(6x^2 - 1)

from first expression

x^2+100=0

x = ±10i

Step-by-step explanation:

x^4+ 95x^2-500=0

What two numbers multiply to -500 and add to 95

-5 * 100 = -500

-5 +100 = 95

(x^2 - 5) (x^2 + 100) = 0

Using the zero product property

x^2 -5 =0          x^2 +100 =0

x^2 -5+5 =0      x^2 +100-100 = 0-100

x^2 =5               x^2 = -100

Answer:

(4,0)

Step-by-step explanation:

So we have the system:

-x+5y=-4

4x+4y=16

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

We are asked to solve this for elimination.

We aren't totally setup for elimination though.

Both equations are in the same form, the form being ax+by=c form, so we are good there.

Now the other requirement is one the columns that contain variables need to be opposites (you will add) or same (you will subtract).

I'm going to multiply the first equation by 4.  The reason I'm going to do this is because the first column will contain -4x and 4x.  Those are opposites.  When you add opposites, you get 0 (they cancel).

So applying the multiplication of 4 to first equation gives:

-4x+20y=-16

4x+   4y=16

----------------- Add the equations now.

0x+24y=0    Again this is called elimination, because we made it to where a                         variable is canceled when combining the equations.

0x+24y=0

0+ 24y=0

     24y=0

Divide both sides by 24:

         y=0

So using one of the equations (you only need one of them) along with the y=0, let's find x.

I'm going to go with -x+5y=-4 with y=0.

Plugging in the 0 for y gives us:

-x+5y  =-4

-x+5(0)=-4

-x+  0  =-4

-x        =-4

Multiply both sides by -1:

x        =4

The solution is (x,y)=(4,0).

ANSWER

The ordered pair is

(4,0)

EXPLANATION

To solve a simultaneous equation using the elimination method means making the coefficient of one of the variables the same. We then add or subtract to eliminate that variable.

The given system has equations:

[tex] - x + 5y = - 4...(1)[/tex]

[tex]4x + 4y = 16...(2)[/tex]

Divide the second equation by 4

[tex]x + y = 4...(3)[/tex]

Add equation (1) and (3) to eliminate x.

[tex] \implies \: 5y + y = - 4 + 4[/tex]

[tex] \implies \: 6y = 0[/tex]

[tex] \implies \: y = \frac{0}{6} = 0[/tex]

Put

[tex]y = 0[/tex]

into the first equation to get:

[tex] - x + 5 \times 0 = - 4[/tex]

[tex] - x = - 4[/tex]

[tex] \therefore \: x = 4[/tex]

Answer:

[tex]\frac{1215}{32}[/tex]

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex], hence

[tex]a_{6}[/tex] = 5 × [tex](\frac{3}{2 )} ^{5}[/tex] = 5 × [tex]\frac{243}{32}[/tex] = [tex]\frac{1215}{32}[/tex]

The sixth term of the geometric sequence is 1215/32 given that the first term a₁=5 and common ratio r=3/2. This can be obtained by using formula for nth term of the geometric sequence.

Sequence is s collection of objects in a particular order and repetitions are allowed.

   Geometric Sequence:

a, ar, ar¹, ..., arⁿ⁻¹ is a geometric sequence, where a is the first term, r is the common ratio and arⁿ⁻¹ is the nth term.

From the definition, nth term of a geometric sequence is arⁿ⁻¹.

Given that, a₁=5 and r=3/2​

To find sixth term, put n=6 ⇒ arⁿ⁻¹=(5)(3/2)⁶⁻¹

                                                       =(5)(3/2)⁵

                                                       =5(3⁵/2⁵)

                                                       =5×(243/32)

                                                       =1215/32

Hence the sixth term of the geometric sequence is 1215/32 given that the first term a₁=5 and common ratio r=3/2.
