The fourth term of the resulting four-term sequence is 206.

Let the four terms of the arithmetic sequence be a a+d, a+2d, and a+3d (where d is common difference)

Let the four terms of the geometric sequence be b, br, br^2, and br^3 (where r is the common ratio)

An arithmetic sequence is a sequence of numbers where the difference between any two consecutive terms is always the same. The difference is called the common difference.

The resulting four-term sequence is a+b, a+d+br, a+2d+br^2, a+3d+br^3

Given that the first three terms of the resulting four-term sequence are 57, 60, and 91, we can set up the following equations:

a + b = 57

a + d + br = 60

a + 2d + br^2 = 91

By substituting the first equation into the second and third equations we get:

d + b(r-1) = 60 - 57 = 3

2d + b(r-1)^2 = 91 - 57 = 34

By substituting the first equation and the second equation into the third one we get:

2(3) + b(r-1)^2 = 34

6+b(r-1)^2 = 34

b(r-1)^2 = 28

Note that either b=28 or b=7. We proceed with casework:

If b=28, then r=2,a=29, and d=25.The arithmetic sequence is 29,4,-21,-46, arriving at a contradiction.

If b=7, then r=3,a=50, and d=-11.The arithmetic sequence is 50,39,28,17, and the geometric sequence is 7,21,63,189. This case is valid.

Therefore, The fourth term of the resulting four-term sequence is [tex]a+3d^{2}+br^{3}= 17 +189 =206[/tex].

What is polynomial ?

A polynomial is a mathematical expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

Let P = (x, y) be a point on L that is four times as far from (2, 5) as it is from (4, 7). Since L contains P, we know that y = x + 3. We also know that the distance from P to (2, 5) is 4 times the distance from P to (4, 7). Using the distance formula, we get:

(x - 2)^2 + (y - 5)^2 = 4[(x - 4)^2 + (y - 7)^2]

Plug in y = x+3 and simplify the equation as ,

(x-2)^2 + (x+3-5)^2 = 4(x-4)^2 + 4(x+3-7)^2

x^2 - 4x + 4 + x^2 - 6x + 9 = 4x^2 - 32x + 48 + 4x^2 - 24x + 36

2x^2 - 30x + 97 = 0

The notations correctly describe the end behavior of the polynomial graphed is,

x → -∞ ⇒ f(x) → -∞

x → ∞ ⇒ f(x) → -∞

What is end behavior of polynomial?

The polynomial function's leading term can be used to determine the end behavior. The behavior of the leading term will dominate the graph because it has the highest power, which means it will grow significantly faster than the other terms as x gets very large or very small.

From the graph we know that the vertex of this parabola is V(0, 8).

This is a maximum y-value. We also know that the parabola opens downward, so the leading coefficient is negative.

Given that the function is even and the leading coefficient is negative, it follows that the graph falls to the left and right.

In a mathematical language this is:

x → -∞ ⇒ f(x) → -∞

x → ∞ ⇒ f(x) → -∞

Hence, the notations correctly describe the end behavior of the polynomial graphed is,

Answer:

The capacity of the pot can be calculated by finding the volume of the clay pot. We can use the formula for the volume of a sphere to find the volume of the inside and outside of the pot and subtract the smaller volume from the larger volume to find the volume of the clay.

Step-by-step explanation:

The formula for the volume of a sphere is:

V = (4/3)πr^3

Where V is the volume and r is the radius.

First, we will calculate the volume of the inside of the pot:

V_inner = (4/3)π(8.2cm)^3 = (4/3)π(530.24cm^3) = 707.68π cm^3

Then, we will calculate the volume of the outside of the pot:

V_outer = (4/3)π(9.1cm)^3 = (4/3)π(710.29cm^3) = 961.12π cm^3

Finally, we will subtract the volume of the inside of the pot from the volume of the outside of the pot to find the volume of the clay:

V_clay = V_outer - V_inner = 961.12π cm^3 - 707.68π cm^3 = 253.44π cm^3

The capacity of the pot is 253.44π cm^3.

Note: The value of pi is 3.14 or approximately 3.14, you can use this value to calculate the capacity of the pot.

True. A function whose values repeat based on positions of a point that moves around a circle is called a sinusoid, using trigonometry approach.

The sine waves oscillate in a smooth, repetitive manner, defined in terms of distance from the [tex]x[/tex] axis to the point on the unit circle.

The main features of a sinusoidal function are its amplitude, its phase, and its frequency. Let us discuss the features one by one :

Amplitude specifies the maximum distance between the x axis i.e. the horizontal axis and the vertical position of the point or a the waveform. It is denoted by [tex]A[/tex].

Phase of a function refers to the horizontal position of the waveform with correspondence to one rotation. The extent or angle by which, a point or a waveform is shifted, is called the phase difference or phase shift.

Frequency is the measurement which tells us about how quickly the sinusoid completes cycles i.e. it simplifies the movement of the sinusoidal wave per unit time.

The measurement of length of the car is 2.25m, when the width is 1.5 meter. Thus, option B is correct.

Measurement is the process of relating numerical values to physical quantities and phenomena. The sciences, engineering, construction, and other technical fields, as well as nearly all daily activities, all depend on measurement. The components, circumstances, restrictions, and theoretical underpinnings of measurement have thus been extensively studied.

Measurements can be made using only the human senses, in which case they are frequently referred to as estimates, or, more frequently, by using instruments.

These instruments can range in complexity from straightforward rules for measuring lengths to extremely complex systems built to detect and measure things that are completely outside the range of the senses, like radio waves from a far-off star or the magnetic moment of a subatomic particle.

Answer:

You don't need to overthink this one, it's not asking for any exact values or estimates so all you do is 40/1.75 which gives you 22.8571428571. Since it's asking for 1 decimal place then the answer would be 22.9 litres of petrol.

Answer:

To solve this problem, we will use the following steps:

Step 1: Nick and Chloe paddled downstream at an average speed of 12 km/h and back upstream at an average rate of 8 km/h. So, we can find the total distance they travelled by finding the distance they travelled downstream plus the distance they travelled upstream.

Step 2: We know that the total trip took 7 hours and they took a 45-minute lunch break. To convert 45 minutes to hours, we can divide 45 by 60, so 45/60 = 0.75 hours.

Step 3: We can then subtract the time they took for lunch break from the total trip time, so 7 - 0.75 = 6.25 hours

Step 4: To find the distance travelled downstream, we can multiply the time spent traveling downstream by the speed of the canoe, so 6.25 x 12 = 75 km

Step 5: To find the distance travelled upstream, we can multiply the time spent traveling upstream by the speed of the canoe, so 6.25 x 8 = 50 km

Step 6: We can then add the distance travelled downstream and the distance travelled upstream to find the total distance travelled, so 75 + 50 = 125 km

Final Answer: Nick and Chloe travelled a total distance of 125 km.

  A = 1/2(21)(11) = 115.5 . . . . square units

The area of the trapezoid is ...

  A = 1/2(b1 +b2)h

  A = 1/2(21 +13)(8) = 136 . . . . square units

The area of the pentagon shown is the sum of these areas:

  115.5 +136 = 251.5 . . . . square units

The radius of the signal is 10 units. The 1st option is the answer

The equation of a circle is a mathematical expression that describes the properties of a circle. It is typically represented in the form of (x - h)²+ (y - k)² = r², where (h, k) is the center of the circle, and r is the radius

Since the border is modeled by the equation (x – 10)² + y²= r² and the boundary is located at (2, 6).

To get the radius of the signal substitute x = 2 and y = 6 into the given equation and solve for r:

(x – 10)² + y²= r²

(2 – 10)² + 6²= r²

(-8)² + 6²= r²

64 + 36 =  r²

100 =  r²

r² = 100

r = √100

r = 10 units

Answer:

Step-by-step explanation:

35% of 230 can be found by first converting 35% to a decimal. To do this, divide 35 by 100.

35/100 = 0.35

Next, multiply the decimal by the total number you want to find the percentage of, which is 230 in this case.

0.35 * 230 = 80.5

So 35% of 230 is 80.5.

Answer:

[tex]y=\frac{2}{3}x+4[/tex]

Step-by-step explanation:

The line passes through [tex](-3,2)[/tex] and [tex](3,6)[/tex], and so has a slope of [tex]\frac{6-2}{3-(-3)}=\frac{2}{3}[/tex].

Since the line has a [tex]y[/tex]-intercept of [tex]4[/tex], the equaton is [tex]y=\frac{2}{3}x+4[/tex].
