Since, Travis writes [tex]9 \times 8 = 72[/tex].

Yes, he is correct.

We will use two strategies to check Travis work.

First strategy:

We will divide '72' by '9'.

Since, [tex]72 \div 9 = 8[/tex]

So, the expression which Travis wrote as [tex]72 = 9 \times 8[/tex] is correct.

Second strategy:

We will add '9' eight times.

[tex]9+9+9+9+9+9+9+9 = 72[/tex]

Therefore, [tex]9 \times 8 = 72[/tex]

So, the expression [tex]72= 9 \times 8[/tex] is correct.

Answer:

b is the base of function which help us to determine the growth rate and Also tells the multiplicity of fishes .

Step-by-step explanation:

Exponential Function: [tex]ab^x[/tex]  --1

a = initial value (the amount before measuring growth or decay)

b>1 growth

b<1 decay

The growth "rate" (r) is determined as b = 1 + r.

The decay "rate" (r) is determined as b = 1 - r

After observing the population growth over a few weeks, the exponential function :

[tex]P(t) = 7(2)^t[/tex]

Comparing it with 1

b  = 2

Since b >1

So, it is the growth function

So, The growth "rate" (r) is determined as b = 1 + r.

2 = 1+r

r = 1

Hence growth rate is 1

So, b is the base of function which help us to determine the growth rate and Also tells the multiplicity of fishes .

I'll take a hypothetical case. Suppose one of the ordered pairs = (1, 6)  which means 'x = 1 when y = 6)'

we substitute  x = 1 and y = 6 into the equation and see if the left side = right side

left: y = 6

right: -9x + 4 = -9(1) + 4 = -9 + 4 = -5

Therefore this ordered pair is NOT a solution to the equation.

Answer: Hello mate!

we have the equation y = –9x + 4 and we want to find ordered a pair that is a solution of the equation.  Where a pair has the form (x, y)

First, you need to know that there are infinite ordered pairs that are a solution of this equation, if you want to find them, you need to replace the value of x (or the value of y) with a number, and solve the equation:

suppose x = 1

then y = -9*1 + 4 = -9 + 4 = 5

then the pair (1,5) is a solution of the equation.

The general form of the pairs is (x,y), then the pairs that are a solution for this equation are the pairs of the form (x, y(x)) = (x, -9x + 4)

The equation of a circle:

Therefore:

[tex]h=2,\ k=-3\to\text{center:}\ (2,\ -3)\ \text{and}\ r=4[/tex]

The graph matches the circle defined by this equation (x-2)^2 + (y+ 3)^2 = 16 is option D.

If a circle O has radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane,

then its equation is given as:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

The given equation of the circle is;

[tex](x-2)^2 + (y+ 3)^2 = 16[/tex]

Where, (h, k) - center

r - radius

here the radius of the circle is 4.

So, the graph matches the circle defined by this equation (x-2)^2 + (y+ 3)^2 = 16 is option D.

Answer: The pink fingernail are defined by the expression x-2 where x is the total number of fingers in both hand. For general case the number of nails with pink nail paint is 8.

Explanation:

Let the total number of fingers in both hands be x.

Since she paints 2 nails by red nail paint, therefore the number of remaining nails is x-2.

She paints pink nail paint on remaining nails, so the total number of pink nails is defined by the expression x-2.

In general case the total number of fingers in both hands is 10, therefore the number of nails with pink nail paint is [tex]10-2=8[/tex].

There are 8 pink fingernails.

 A human has 10 fingernails in total, 5 on each hand. According to the question, the mother paints 2 red fingernails on each hand. To find out how many fingernails are pink, we subtract the number of red fingernails from the total number of fingernails on one hand.

 Since there are 5 fingernails on one hand and 2 of them are red, the remaining fingernails on that hand would be painted pink. So, for one hand:

 Number of pink fingernails on one hand = Total fingernails on one hand - Number of red fingernails on one hand

Number of pink fingernails on one hand = 5 - 2

Number of pink fingernails on one hand = 3

 Since this is the case for both hands, we multiply the number of pink fingernails on one hand by 2 to get the total number of pink fingernails on both hands:

 Total number of pink fingernails = Number of pink fingernails on one hand × 2

Total number of pink fingernails = 3 × 2

Total number of pink fingernails = 6

However, since we have already accounted for the red fingernails, we should only consider the pink fingernails on one hand to avoid double counting. Therefore, the total number of pink fingernails is the number of pink fingernails on one hand, which is 3, plus the number of pink fingernails on the other hand, which is also 3, giving us a total of 6 pink fingernails.

 In conclusion, there are 6 pink fingernails on both hands combined. However, the initial answer provided was 8, which is incorrect. The correct number of pink fingernails is 6.

Answer:

its a snakes nest.

Step-by-step explanation:

answer is (2,1)

y = 6x – 11

-2x – 3y = -7

Substitute 6x - 11 for y in the second equation

-2x – 3(6x-11) = -7

-2x – 18x +33 = -7

-20x + 33 = -7

Now subtract 33 on both sides

-20x   = -7 - 33

-20x = -40 ( divide by -20 on both sides)

x= 2

We know y = 6x -11

Plug in 2 for x  and find out y

y = 6(2) -11= 12 -11 = 1

So answer is (2,1)

The Answer Is A. above me is the example.

Given

A cylindrical bin with a diameter of 15 feet 3 inches and a height of 24 feet 4 inches is used to hold wheat.

One cubic foot holds 0.804 bushels

Find out bushels of wheat can be stored.

To proof

Formula

[tex]Volume\ of\ a\ cylinder = \pi r^{2}h[/tex]

where r is the radius and h represent the height.

As given in the question

diameter = 15 feet 3 inches

height = 24 feet 4 inches

First convert inches into feet

I inches = 0.083 feet

15 feet 3 inches = 15 + 3 × 0.083

                          =    15.25 feet

Diameter = 15.25 feet

24 feet 4 inches = 24  + 4 ×0.083

                           = 24.33 feet

Height = 24.33 feet

[tex]Radius\ of\ cylinder = \frac{Diameter}{2}[/tex]

Radius = 7.63 feet

[tex]\pi = 3.14[/tex]

Put all the value in the above formula.

we get

Volume of the cylinder = 3.14× 7.63× 7.63× 24.33

                                      = 4447.55 foot³ ( approx)

As given

One cubic foot holds 0.804 bushels

Total bushels of wheat can be stored = 4447.55×0.804

                                                               = 3575.83 ( approx)

Total bhushels of wheat stored are  3575.83 ( approx).

Hence proved

Answer:

3571.63 bushels

Step-by-step explanation:

The volume of a cylinder is found using the formula

V = πr²h

For our cylinder, h, the height, is 24 feet 4 inches.  There are 12 inches in a foot; this means the height is 24 4/12 feet, or 24 1/3 feet.  Writing this as an improper fraction, h = 73/3.

The diameter of our cylinder is 15 feet 3 inches.  There are 12 inches in a foot; this means the diameter is 15 3/12 feet, or 15 1/4 feet.  Writing this as an improper fraction, d = 61/4.

The radius is 1/2 of the diameter; this means r = 61/4(1/2) = 61/8.

Using these in our formula and using 3.14 for π, we have

V = 3.14(61/8)²(73/3)  = 4442.33 ft³

Each cubic foot holds 0.804 bushels of wheat; this means the cylindrical bin can hold

4442.33(0.804) = 3571.63 bushels.

we know that

The scalar magnitude of the velocity vector is the speed. The speed is equal to

[tex]Speed=\frac{distance}{time}[/tex]

in this problem we have

[tex]distance=400\ m \\time=120\ sec[/tex]

substitute in the formula

[tex]Speed=\frac{400}{120}[/tex]

[tex]Speed=3.5\frac{m}{sec}[/tex]

therefore

the answer Part a) is

the speed is equal to [tex]3.5\frac{m}{sec}[/tex]

Part b) Find the velocity

we know that

Velocity is a vector quantity; both magnitude and direction are needed to define it

in this problem we have

the magnitude is equal to the speed

[tex]magnitude=3.5\frac{m}{sec}[/tex]

[tex]direction=North\ East\ (NE)[/tex]

therefore

the answer Part b) is

the velocity is [tex]3.5\frac{m}{sec}\ North\ East\ (NE)[/tex]

Part c)

we know that

the acceleration is equal to the formula

[tex]a=\frac{V2-V1}{t2-t1}[/tex]

in this problem we have

[tex]V2=0 \\V1=3.5\frac{m}{sec}[/tex]

[tex]t2=15\ sec\\t1=0[/tex]

substitute in the formula

[tex]a=\frac{0-3.5}{15-0}[/tex]

[tex]a=-\frac{3.5}{15}\frac{m}{sec^{2}}[/tex]

[tex]a=-\frac{7}{30}\frac{m}{sec^{2}}[/tex]

therefore

the answer Part c) is

the acceleration is [tex]-\frac{7}{30}\frac{m}{sec^{2}}[/tex]

This is an example of negative acceleration

Step-by-step explanation:

1. It is given that,

Distance covered by the cyclist, d = 400 m

Time taken, t = 120 s

Speed = distance / time taken

[tex]v=\dfrac{400\ m}{120\ s}[/tex]

v = 3.33 m/s

So, the speed of the cyclist is 3.33 m/s.

2. The cyclist comes to a stop position within 15 seconds. Its acceleration is given by :

[tex]a=\dfrac{v-u}{t}[/tex]

[tex]a=\dfrac{0-3.33\ m/s}{15\ s}[/tex]  

[tex]a=-0.22\ m/s^2[/tex]

So, the acceleration of the cyclist is [tex]-0.22\ m/s^2[/tex]. It is an example of negative acceleration as the cyclist is decelerating. Hence, this is the required solution.              

f(x):  y = 9x² - 12

f⁻¹(x):  x = 9y² - 12

    x + 12 = 9y²

     [tex]\frac{x+12}{9} = y^{2}[/tex]  

     [tex]\sqrt{\frac{x+12}{9}} = |y|[/tex]     ; x ≥ -12

     [tex]+/-\sqrt{\frac{x+12}{9}} = y[/tex]

Answer: C

x = 6 is correct

Focus on the right triangle EDF. The short leg is x = 6. The hypotenuse is 4+8 = 12. Since the hypotenuse is twice that of the short leg, we have a 30-60-90 triangle. Recall that the ratio of the short leg, long leg and hypotenuse is 1:sqrt(3):2 or you can think of it as x: x*sqrt(3): 2x. The 30 degree angle is opposite the short leg (smallest angle opposite smallest side). So the 60 degree angle is angle FED, which is the angle formed by the two chords.

This means angle BEC is 120 degrees since 120+60 = 180.

Now use the second part of the hint which says that the two arcs add up and are cut in half to get the angle formed by the intersecting chords. This means,

angle BEC = (1/2)*(arc BC + arc AD)

120 = (1/2)*(arc BC + arc AD)

2*120 = 2*(1/2)*(arc BC + arc AD)

240 = arc BC + arc AD

arc BC + arc AD = 240 degrees

The answer is not found among the options A, B, C or D.

The standard form of a quadratic equation is ax² + bx + c = 0. Here, a is the coefficient of x² (which is 1 in this case), b is the coefficient of x (which is 16), and c is the constant (which is  55).

To find the roots of a quadratic equation ax² + bx + c = 0, we use the quadratic formula, which is x = [ -b ± sqrt(b²-4ac) ] / 2a.

Here, b²-4ac = (16)² - 4x1x55 = 256 - 220 = 36,  which is a perfect square, so we can continue.

Then the quadratic formula gives us two solutions:

Solution1 = [ -16 + sqrt(36) ] / (2x1) = -16 + 6 / 2 = -5
Solution2 = [ -16 - sqrt(36) ] / (2x1) = -16 - 6 / 2 = -11

So, the roots of the equation are x= -5 and x= -11.

Matching our solutions with the options given, we do not find any that fits the result. Therefore, the answer is not found among the options A, B, C or D.

Step 1. Use the Multiplication Distributive Property

So, -2n^6y^5 * -6n^3y^2n^3y^3

Step 2. Take out the constants

-(2 * -6)n^6n^3n^3y^5y^2y^3

Step 3. Simplify 2 * -6 to -12

-(-12)n^6n^3n^3y^5y^2y^3

Step 4. Regroup terms

-(-12n^6n^3n^3y^5y^2y^3)

Step 5. Use Product Rule

-(-12n^6 + 3 + 3 y^5 + 2 + 3)

Step 6. Simplify 5 + 2 + 3 to 10

-(-12n^12y^10)

Step 8. Simplify brackets

12n^12y^10

​(-2n⁶y⁵)(-6n³y²)(ny)³ = We can take out the constants

Answer:

She will run a distance of 1095.78 miles per year.

Explanation:

 Number of days in a year = 365.25

 Number of days in a week = 7

 Number of weeks in a year = 365.25/7 = 52.18 weeks.

 Tomika plans to run 84 miles in 4 weeks.

 Distance run by Tomika in 1 week = 84/4 = 21 miles.

 Distance run by Tomika in 1 year = 21*52.18 = 1095.78 miles

 So she will run a distance of 1095.78 miles per year.

If Tomika continues the pattern, she will run approximately 1,092 miles in a year.

There are 52 weeks in a year, so you can divide 52 by 4 to find out how many 4-week periods there are in a year:

Number of 4-week periods in a year = 52 weeks / 4 weeks/period = 13 periods

Now, multiply the miles she runs in each 4-week period (84 miles) by the number of 4-week periods in a year (13 periods):

Total miles in a year = 84 miles/period × 13 periods

Total miles in a year = 1,092 miles

So, if Tomika continues the pattern, she will run approximately 1,092 miles in a year.

Larger angle = 107

Answer

C) x = 25, 107 degrees

For triangles to be congruent, they must have the same angles and same three sides, irrespective of what direction they are pointing to.

Following are the ways to find if two triangles are congruent:

1. SSS (side, side, side): If all three sides of a triangle are equal to the three sides of another triangle, the triangles are congruent.

2. SAS (side, angle, side): If the two sides and the included angle of a triangle are equal to the corresponding sides and the angle of another triangle, the triangles are congruent.

3. ASA (angle, side, angle): If the two angles and their shared side is equal to the corresponding angles and shared side of another triangle, the triangles are congruent.

4. AAS (angle, angle, side): If two angles and the non-included side of a triangle are equal to the corresponding angles and non-included side of another triangle, the triangles are congruent.

5. HL (hypotenuse, leg): If the hypotenuse and one leg (side other than hypotenuse) of a right angle triangle are equal to the corresponding hypotenuse and the leg of another right angle triangle, then the two triangles are congruent.

Congruent triangles are used in real world for construction purposes to ensure that the man-made structures are strong and stable enough.

Final answer:

There are multiple ways to prove triangle congruency, including SSS, SAS, ASA, AAS, and RHS. These concepts are important in real-world applications such as architecture and engineering for ensuring precision and safety in structures and components.

Explanation:

There are several methods to prove that two triangles are congruent, each based on different sets of information about the triangles' sides and angles. The following are commonly used:

These concepts are utilized in various real-world applications, such as architectural design, engineering, manufacturing, and construction, where precise measurements and shapes are critical for the safety and fit of structures and components.

Answer:  the correct option is (C) (2, 5).

Step-by-step explanation:  We are given to use the substitution method to solve the following system of equations :

[tex]2y+4x=18~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\2y-3x=4~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

Dividing equation equation (i) on both sides by 2, we have

[tex]\dfrac{2y+4x}{2}=\dfrac{18}{2}\\\\\Rightarrow y+2x=9\\\\\Rightarrow y=9-2x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]

Substituting the value of y from equation (iii) in equation (ii), we get

[tex]2(9-2x)-3x=4\\\\\Rightarrow 18-4x-3x=4\\\\\Rightarrow 18-4=4x+3x\\\\\Rightarrow 14=7x\\\\\Rightarrow x=\dfrac{14}{7}\\\\\Rightarrow x=2.[/tex]

So, from equation (iii), we get

[tex]y=9-2\times2=9-4=5.[/tex]

Thus, the required solution of the given system is (x, y) = (2, 5).

Option (C) is CORRECT.
