Answer:

2 the answer is 2/1 but just write 2

Step-by-step explanation:

Dilation of a polygon by a factor of 8 enlarges the polygon without changing the slope of the line. Therefore, the slope of AB and A'B' are the same. Further information is needed to provide a numerical value.

Since the polygon is dilated by a scale factor of 8, the new image A′B′C′D′ is an enlargement of the original polygon ABCD by a factor of 8. The slope of a line in a dilation remains the same, even if the length of the line is changed. Essentially, the steepness of a line isn't affected by dilations. Therefore, the slope of AB and A'B' are same. Since the slope of AB is not given in the question, it's necessary to have that information to answer your question completely.

Answer:

10 square units

Step-by-step explanation:

We want to find the area under the curve [tex]f(x)=x+3[/tex] from x=1 to x=3.

We use definite integrals to find this area.

[tex]\int\limits^3_1 {x+3} \, dx[/tex]

We integrate to obtain:

[tex]\frac{x^2}{2}+3x|_1^3[/tex]

We evaluate the limits to get:

[tex]\frac{3^2}{2}+3(3)-(\frac{1^2}{2}+3(1))[/tex]

[tex]4.5+9-0.5-3=10[/tex]

Therefore the area under the curve from x=1 to x=3 is 10 square unit.

Answer:

The constant of variation is

[tex]k= 5[/tex]

Step-by-step explanation:

First we must write the relationship as an equality.

If q varies inversely with the square of m, this means that when m ^ 2 increases then q decreases.

If q varies directly with the product of r and x this means that when r * x increases q increases.

Then the relationship is:

[tex]q = k\frac{rx}{m^2}[/tex]

Where k is the constant of proportionality

Then if:

[tex]q=2.5\\\\m=4\\\\r*x=8[/tex]

[tex]2.5 = k\frac{8}{4^2}[/tex]

We solve for k

[tex]2.5 = k\frac{8}{16}[/tex]

[tex]2.5 = k\frac{1}{2}[/tex]

[tex]k= 5[/tex]

Answer:

[tex]a =111.1\ m/s^2[/tex]

Step-by-step explanation:

The formula to calculate the average acceleration is:

[tex]a =\frac{s_2-s_1}{t_2-t_1}[/tex]

Where s is the speed of the object and t is the time it takes the object to change its speed [tex]s_1[/tex] to the speed [tex]s_2[/tex]

In this case we have that:

[tex]t_2-t_1 = 5\ sec[/tex]

[tex]s_1 = 500\ km/h = 500*\frac{1\ h}{3600\ s}*\frac{1000\ m}{1\ km}=138.89\ m/s[/tex]

[tex]s_2= 2500\ km/h = 2500*\frac{1\ h}{3600\ s}*\frac{1000\ m}{1\ km}=694.44\ m/s[/tex]

8,076 ....................

Answer:

8076

Step-by-step explanation:

You need a 4-digit number. The leftmost digit is the thousands digit (T). The next digit to the right is the hundreds digit (H). The third digit from the left is the tens digit (E), and the rightmost digit is the ones digit (O).

Using T, H, E, and O, as shown above, the number will have the form:

THEO

Now you replace each letter with the correct digit.

"eight thousand, seventy-six" has no hundreds, so let's include hundreds:

"eight thousand (T = 8), zero hundreds (H = 0), and seventy (E= 7)-six (O = 6)"

8076

The important thing is to remember to include a 0 as the digit for the hundreds place.

Answer:

6.13

Step-by-step explanation:

Using Sine Law we know that

[tex]\dfrac{a}{SinA}=\dfrac{b}{SinB}=\dfrac{c}{SinC}[/tex]

Using your figure let's assign sides and angles:

A=? B = 60° C = 70°

a = 5 b = ? c = x

If we put that into our formula:

[tex]\dfrac{5}{Sin?}=\dfrac{?}{Sin60}=\dfrac{x}{Sin70}[/tex]

Notice that we have too many unknowns. We need to complete at least one ratio to do this, so how do we do this?

Notice we have 2 angles given, so we solve for the third angle. The sum of all angles in any triangle is always 180°

∠A + ∠B + ∠C= 180°

∠A + 60° + 70° = 180°

∠A + 130° = 180°

∠A = 180° - 130°

∠A = 50°

Now we can use this to solve for x.

[tex]\dfrac{5}{Sin50}=\dfrac{x}{Sin70}\\\\\dfrac{(5)(Sin70)}{Sin50} = x\\\\\dfrac{4.6985}{0.7660}=x\\\\6.1338 =x[/tex]

So the closest answer would be 6.13

Answer:

The correct answer option is 6.13.

Step-by-step explanation:

We are given a scalene triangle which has no equal side and we are to find the unknown side length x.

Since the total measure of angles of a triangle is 180°, so we can find the measure of the unknown angle.

180° - 70° + 60° = 50°

Now we can use the sine formula to find the value of x.

[tex]\frac{x}{sin70} =\frac{5}{sin50}[/tex]

[tex]x=\frac{5}{sin50} \times sin70[/tex]

[tex]x=6.13[/tex]

Answer:  The required probability that the random student selected plays both tennis and basketball is 22%.

Step-by-step explanation:  Given that in a school, 40% of the students play tennis, 24% of the students play baseball, and 58% of the students playing neither tennis or baseball.

We are to find the probability that a random student picked plays both tennis and basketball.

Let the total number of students in the school be 100. Also, let T and B represents the set of students who play tennis and basketball respectively.

Then, according to the given information, we have

[tex]n(T)=40,~~~n(B)=24.[/tex]

The number of students who play either tennis or basketball will be represented by T ∪ B.

And so, we have

[tex]n(T\cup B)=100-58=42.[/tex]

We know that the number of students who play both tennis and basketball is denoted by T ∩ B.

From set theory, we get

[tex]n(T\cup B)=n(T)+n(B)-n(T\cap B)\\\\\Rightarrow n(T\cap B)=n(T)+n(B)-n(T\cup B)\\\\\Rightarrow n(T\cap B)=40+24-42\\\\\Rightarrow n(T\cap B)=22.[/tex]

Thus, the required probability that the random student selected plays both tennis and basketball is 22%.

Final answer:

Brandy's mistake was not converting the diameter to the radius before applying the area formula A = πr². The correct area of a circle with a diameter of 12 cm is 113.04 cm², but it should be reported as 110 cm² to maintain two significant figures.

Explanation:

The error in Brandy's solution for finding the area of a circle with a diameter of 12 cm lies in not first converting the diameter into the radius. The formula for the area of a circle is A = πr², where r is the radius and π (pi) is approximately 3.14. Since the radius is half of the diameter, for a diameter of 12 cm, the radius is 6 cm. Thus, the correct calculation is A = 3.14 × 6².

Correct solution:

A = 3.14 × 6 cm²

A = 3.14 × 36 cm²

A = 113.04 cm²

As for the significance of figures, since the radius has two significant figures (6 cm), the calculated area should also be limited to two significant figures, rounding to 110 cm².

f^-1(x) = (x - 2)/4 ⇒ 1st answer

Step-by-step explanation:

* Lets revise how to find the inverse function

- At first write the function as y = f(x)

- Then switch x and y

- Then solve for y

- The domain of f(x) will be the range of f^-1(x)

- The range of f(x) will be the domain of f^-1(x)

* Now lets solve the problem

∵ f(x) = 4x + 2

∴ y = 4x + 2 ⇒ switch x and y

∴ x = 4y + 2 ⇒ subtract 2 from both sides

∴ x - 2 = 4y ⇒ ÷ 4 both sides

∴ (x - 2)/4 = y

∴ f^-1(x) = (x - 2)/4

* f^-1(x) = (x - 2)/4

Step-by-step explanation:

The interquartile range is the value of quartile 3 minus quartile 1.

The "box" part of this diagram has 3 lines, the left most, the middle, and the rightmost.

The leftmost line is Quartile 1. The right most is Quartile 3.

Hence

interquartile range = quartile 3 - quartile 1

Looking at the box plot, we can see that each small line in the number line is 2 units.

The leftmost line (quartile 1 ) is at 1 unit left of 30, so that is 30 -2 = 28

The rightmost line (quartile 3) is at  1 unit right of 40, so that is 40 + 2 = 42

Hence,

Interquartile range = 42 - 28 = 14

Final Answer:

The proposed new cereal box design has dimensions of 6 inches in length, 2 inches in width, and 8 inches in height. This design maintains the original cereal volume of 96 cubic inches while reducing the surface area to 104 square inches.

Explanation:

The formula for the surface area [tex](\(A\))[/tex] of a rectangular prism is given by:

[tex]\[ A = 2lw + 2lh + 2wh \][/tex]

For the original box with dimensions 8 inches in length [tex](\(l\)),[/tex] 1 inch in width [tex](\(w\)),[/tex] and 12 inches in height [tex](\(h\))[/tex]:

[tex]\[ A_{\text{original}} = 2(8 \times 1) + 2(8 \times 12) + 2(1 \times 12) = 232 \][/tex]

For the proposed new design with dimensions 6 inches in length, 2 inches in width, and 8 inches in height:

[tex]\[ A_{\text{new}} = 2(6 \times 2) + 2(6 \times 8) + 2(2 \times 8) = 104 \][/tex]

Comparing the surface areas, the new design significantly reduces it from 232 square inches to 104 square inches. This reduction in surface area indicates that the proposed design will require less material for manufacturing.

By maintaining the original cereal volume of 96 cubic inches while decreasing the surface area, the proposed cereal box design is more cost-effective to manufacture. The optimization of dimensions ensures that the same cereal quantity can be accommodated with a reduction in manufacturing costs.

6=n   and -2=n

Step-by-step explanation:

The distance between two points is found by

d = sqrt(( x2-x1)^2 + (y2-y1)^2)

5 = sqrt(( n-2)^2 + (4-1)^2)

5 = sqrt(( n-2)^2 + (3)^2)

Square each side

5^2 = sqrt(( n-2)^2 + (3)^2)^2

25 = ( n-2)^2 + (3)^2

25 = (n-2)^2 +9

Subtract 9 from each side

25-9 = (n-2)^2 +9-9

16 = (n-2)^2

Take the square root of each side

sqrt(16) = sqrt( (n-2)^2)

±4 = n-2

Add 2 to each side

2±4 = n-2+2

2 ±4 = n

A box contains 100 colored chips

Some are yellow and,

Some are green.

John has recorded 57 yellow chips and 19 green chips.

The ratio of yellow chips to green chips is 57:19 simplified becomes; 3:1

The number of green chis is [tex]\frac{1}{3 + 1}[/tex] × 100 = [tex]\frac{1}{4}[/tex] × 100 = 25

For this case we must find an expression equivalent to:

[tex]\frac {\sqrt [7] {x ^ 2}} {\sqrt [5] {y ^ 3}}[/tex]

By definition of properties of powers and roots we have:

[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

So, rewriting the expression we have:

[tex]\frac {x ^ {\frac {2} {7}}} {y ^ {\frac {3} {5}}} =[/tex]

By definition of power properties we have:

[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]
