Step-by-step explanation:

Let x represent the smallest of the three numbers. Then the other two are (x+2) and (x+4). Their sum is ...

  x + (x+2) +(x+4) = 162

  3x = 156 . . . . . . . . . . . .subtract 6

  x = 156/3 = 52

The smallest of the three numbers is 52.

I like to work problems like this by considering the average number. Here, the average of the three numbers is 162/3 = 54, the middle number of the three. Then the smallest of the three consecutive even numbers is 2 less, or 52.

To find the fraction of cupcakes with chocolate sprinkles, we multiply 5/7 (chocolate cupcakes) by 1/5 (those with sprinkles), resulting in 1/7 of all cupcakes having chocolate sprinkles.

The student's question is about calculating the fraction of cupcakes with chocolate sprinkles from the total number of cupcakes bought for a party. To find the answer, we can use a two-step process involving fractions. Since 5/7 of the cupcakes are chocolate and of those, 1/5 have chocolate sprinkles, we multiply these two fractions to find the fraction of all cupcakes that have chocolate sprinkles.

The calculation is as follows: (5/7) × (1/5) = 5/35 = 1/7. Thus, 1/7 of the cupcakes have chocolate sprinkles. This approach to solving the problem demonstrates the basic principle of multiplying fractions to determine a portion of a subset.

Step-by-step explanation:

The vertex of the parabola [tex]y=4x^2-8x-12[/tex] is (1, -16).

To find the coordinates of the vertex of the parabola [tex]y=4x^2-8x-12[/tex], we can use the formula x = -b/2a, where a, b, and c are the coefficients of the quadratic equation.

In this case, a = 4 and b = -8.

Plugging these values into the formula, we get x = -(-8)/(2*4) = 1.

Now, we can substitute this value of x back into the equation to find the corresponding y-coordinate.

Plugging x = 1 into y = [tex]4x^2-8x-12[/tex], we get y = [tex]4*1^2 - 8*1 - 12 = -16[/tex].

Therefore, the vertex of the parabola is (1, -16).

Final answer:

The vertex of the parabola [tex]y=4x^2-8x-12[/tex] is found by completing the square and transforming the equation into vertex form, resulting in the vertex coordinates at (1, -16).

Explanation:

To find the coordinates of the vertex of the parabola given by the equation [tex]y=4x^2-8x-12,[/tex] we use the fact that the vertex form of a parabola's equation is[tex]y=a(x-h)^2+k,[/tex]where (h, k) is the vertex of the parabola. In this case, we can complete the square to transform the given equation into vertex form. To do that, we can factor out the coefficient of [tex]x^2[/tex] from the first two terms:

[tex]y = 4(x^2 - 2x) - 12[/tex]

Now, we add and subtract the square of half the coefficient of x inside the parentheses, which is [tex](2/2)^2 = 1:[/tex]

[tex]y = 4(x^2 - 2x + 1 - 1) - 12[/tex]

[tex]y = 4((x - 1)^2 - 1) - 12[/tex]

[tex]y = 4(x - 1)^2 - 4 - 12[/tex]

[tex]y = 4(x - 1)^2 - 16[/tex]

Now that we have the equation in vertex form, we can see that the vertex of the parabola is at (1, -16).

Answer:

Part a) The railroad ties are parallel

Part b) One railroad tie is perpendicular to both rails

Step-by-step explanation:

Part a) The railroad ties are each perpendicular to one rail

we know that

if one line is perpendicular to several other lines, then the other lines are parallel

Conclusion:

If the railroad ties are each perpendicular to one rail then the railroad ties are parallel

That means----> The slopes of the railroad ties are equal and they are opposite reciprocal to the slope of the rail

Part b) The rails are parallel. One railroad tie is perpendicular to one rail

we know that

if two lines are parallel and another line is perpendicular to one of them, then this line is perpendicular to both lines

Conclusion:

If One railroad tie is perpendicular to one rail, then one railroad tie is perpendicular to both rails

That means ---> The slopes of the railroad ties are opposite reciprocal to the slope of the rail

Final answer:

The railroad ties are perpendicular to both rails, and the rails are parallel to each other, reflecting principles of linear perspective in geometry.

Explanation:

The student's questions relate to geometry, specifically the properties of lines and angles about railroad tracks and railroad ties. When analyzing these geometric structures, we draw on concepts such as parallel lines, and perpendicular lines, and the characteristics of their interaction.

Analysis of Statements

Therefore, we can conclude that the railroad ties are perpendicular to both rails and that the rails are parallel to each other. This aligns with linear perspective and the visual effect of perpendicular lines (orthogonal) converging at a vanishing point as they recede into the distance.

After 4 days, the number of people attending both conferences be the same.      

Step-by-step explanation:

We are given the following in the question:

Maths conference:

Number of people already signed = 7

Number of people who sign up each day = 2

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

 [tex]f(x) = 7+2x[/tex]

History conference:

Number of people already signed =11

Number of people who sign up each day = 1

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

 [tex]g(x) =11+x[/tex]

Both conference will have same number of people when

[tex]f(x) = g(x)\\\Rightarrow 7 + 2x = 11+x\\\Rightarrow x = 4[/tex]

Thus, after 4 days, the number of people attending both conferences be the same.

Answer:

26.04 inches

Step-by-step explanation:

A revolution is in the shape of a circle.

We can therefore say that the bike tires that complete 20 revolutions complete the length of 20 circumferences of the tires.

The length of the 20 revolutions (20 circumferences) is 136 ft

Therefore, the length of one revolution and hence, one circumference is:

C = 136 / 20 = 6.8 ft

The circumference of a circle is given as:

C = pi * d

Where d = diameter of the circle.

Hence, the diameter of the tire will be:

6.8 = 3.14 * d

d = 6.8 / 3.14

d = 2.17 ft

1 foot is equal to 12 inches, hence, 2.17 ft in inches will be:

2.17 * 12 = 26.04 inches

The diameter of the tire is 26.04 inches.

Step-by-step explanation: complete the square, than use the binomial formula, then simplify and expand

Answer:

equation is y = (x+1)(x+11)

vertex: (-1,-11)

Step-by-step explanation:

y = x^2 + 12x + 11. The last value, the value 11 is how we can determine our values in the equation. First we need to find the factors of positive 11 which are: -11 * -1 and 1*11. now we will look at the second portion the 12x. As we can see the value is positive. Now we will add the two factors together and see which one gives us positive 12. The factors 1 and 11 make positive 12. Now we simply just need to add those values to x. When this is factored down or in other words vertex form, the equation is y = (x+1)(x+11). The vertex is what value would make the equation equal 0.  Since -1 + 1 equals 0 then that is one of the vertex and since -11 + 11 equal 0 that also makes that a vertex. This makes the vertex -1,-11.

Answer:

1.2^n

Step-by-step explanation:

since a single dot brings about an increment by 20%, the total magnification becomes 120% after the click. The common ratio = 120 / 100 = 1.2

the formula  becomes 1.2^n  

The formula for the nth term of the geometric sequence that represents the magnification of each zoom level is an = (1.2)n-1.

In this problem, you are looking at a geometric sequence that represents the magnification of each zoom level on a map. A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

In this case, the common ratio is 1 + 0.2 = 1.2 because the magnification increases by 20% (or 0.2 in decimal form) each time. We can denote the nth termed 'an'. The general formula for the nth term in a geometric sequence is: an = a1 * rn-1.

Since the initial magnification doesn't specify a specific value, we will take a1 as 1 for this case. Substituting these values into the formula yields: an = 1 * (1.2)n-1, or just an = (1.2)n-1.

Answer:

 (7, 0), (-3, 0)

Step-by-step explanation:

The x-intercepts are the values of x that make the factors zero. A zero factor makes the value of the function be zero.

  x - 7 = 0   ⇒   x = 7

  x + 3 = 0   ⇒   x = -3

The corresponding (x, y) coordinates are ...

  (7, 0), (-3, 0)

The x-intercepts of the quadratic function f(x) = (x-7)(x+3) are (7, 0) and (-3, 0).

The question is about finding the x-intercepts of the quadratic function f(x) = (x-7)(x+3). The x-intercepts occur where the function equals zero, so we set f(x) = 0 and solve for x. This gives us two solutions:

x - 7 = 0, which simplifies to x = 7

x + 3 = 0, which simplifies to x = -3

Therefore, the x-intercepts of the function are at (7, 0) and (-3, 0), with the one having the larger x-value being (7, 0).

Answer: he invested $8600 in bonds.

Step-by-step explanation:

Let x represent the part of his money that he invested in stocks.

Let y represent the part of his money that he invested in bonds.

Ben invested part of his $15,000 savings in stocks paying 4.25% simple interest annually. He invested the rest in bonds paying 3.75% simple interest annually. It means that

x + y = 15000

The interest that he would earn on the amount invested in stocks after 1 year is

4.25/100 × x = 0.0425x

The interest that he would earn on the amount invested in bonds after 1 year is

3.75/100 × y = 0.0375y

If Ben earned $594.50 in interest after one year, it means that

0.0425x + 0.0375y = 594.5- - - - - - 1

Substituting x = 15000 - y into equation 1, it becomes

0.0425(15000 - y) + 0.0375y = 594.5

637.5 - 0.0425y + 0.0375y = 594.5

- 0.0425y + 0.0375y = 594.5 - 637.5

- 0.005y = - 43

y = - 43/- 0.005

y = $8600

x = 15000 - 8600

x = $6400

The circumference of a circle with a radius of 9 meters, using pi as 3.142, is calculated as 56.6 meters when rounded to one decimal place.

The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius of the circle.

In this case, the radius of the circle is 9m. Let's substitute this value into the formula:

C = 2 × 3.142 × 9

C = 56.556m

Therefore, the circumference of the circle is 56.6 meters (rounded to 1 decimal place).Calculating the Circumference of a Circle

To calculate the circumference of a circle with a radius (r) of 9 meters and using π (pi) as 3.142, we use the formula C = 2πr. By plugging in the given values, we get C = 2 × 3.142 × 9m. Performing the multiplication, we find that the circumference is 56.556 meters. Since we need to give our answer with one decimal place, we round to 56.6 meters.
