The Panther I traveled approximately 2413 miles before reaching a speed of 130 mph.
What is a trapezoid?A trapezoid is a quadrilateral having two parallel bases and one set of other sides called legs.
To estimate the distance traveled by the Panther I, we need to approximate the area under the velocity curve between 0 and 25.7 seconds. We can divide the area into trapezoids using the data given in the table.
The first trapezoid has a height of 30 mph and a base of 1.8 seconds. The second trapezoid has a height of 40 mph and a base of 1.3 seconds (the difference between 3.1 and 1.8).
Continuing in this way, we get the following table:
Speed Height
Range (mph) Base (s) Area (mph * s)
0-30 30 1.8 54
30-40 40 1.3 52
40-50 50 1.1 55
50-60 60 1.3 78
60-70 70 1.9 133
70-80 80 1.8 144
80-90 90 2.3 207
90-100 100 3.1 310
100-120 120 6.3 756
120-130 130 4.8 624
To find the total area, we add up the areas of all the trapezoids:
54 + 52 + 55 + 78 + 133 + 144 + 207 + 310 + 756 + 624 = 2413
Therefore, the Panther I traveled approximately 2413 miles before reaching a speed of 130 mph.

Erik spends $680 for cable television service. The cable company offers a deal that promises Erik 3 free months of cable if he signs a contract with them for $40 per month.
Complete the equation below to find the number of months that Erik will have cable television service with this deal. Use m to represent the number of months.
Answer:
Step-by-step explanation:
The cable company offers Erik 3 free months of cable if he signs a contract with them for $40 per month. This means that Erik will pay for (m - 3) months of cable service, since he will get 3 months for free. So the cost of the cable service for (m - 3) months is:
Cost = $40 per month x (m - 3) months
Cost = $40m - $120
We know that Erik spent $680 for the cable television service. So we can set up an equation to relate the cost to the number of months:
$40m - $120 = $680
To solve for m, we can isolate the variable on one side of the equation:
$40m = $800
m = 20
Therefore, Erik will have cable television service for 20 months with this deal.

The area of the circle is 78.5m² And when the radius is doubled, the area will be 314m².
The ratio of the larger circle to the smaller circle is 4 : 1
What is area of circle?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. The area is measured in squared units.
The area of a circle is expressed as :
A = πr²
A = 3.14 × 5²
A = 3.14 × 25
A = 78.5m²
When the radius is doubled, i.e
r = 5×2 = 10m
A = πr²
A = 3.14 × 100
A = 314m²
Therefore the area of the new circle is 314m²
The ratio of the area of the larger circle to the area of the smaller circle is ;
314/78.5 = 4/1 = 4 : 1
therefore the ratio of the larger circle to the smaller circle is 4 : 1

Answer:
Step-by-step explanation:
The statement "65% of 150 students" could represent the estimate that 100 students attended the school's play.
To see this, we can calculate 65% of 150:
0.65 x 150 = 97.5
Since 97.5 is close to 100, it is possible that the estimate was based on 65% of 150 students.
The other statements do not come close to 100, so they are not likely to represent the estimate that 100 students attended the school's play.

Nick, 10 feet above the water level in a ship off shore, finds that the angle of elevation of the light is 5; Find the length of the line of sight (light beam) from the ship to Nicole. Round to the
nearest tenth.
The length of the line of sight from the ship to Nicole is approximately 2046.1 feet, rounded to the nearest tenth.
What is trigonometry?Trigonometry is a branch of mathematics that studies the relationships between triangle sides and angles.
The term trigonometry is derived from the Latin derivative of the Greek words for triangle (trigonon) and measurement (measur) (metron).
Trigonometry is a branch of mathematics concerned with angle relationships and length ratios.
Let's assume that the distance between Nicole's window and Nick's position is "x" feet. Then, we can use trigonometry to set up the following equation:
tan(5) = (175 + 10) / x
Simplifying and solving for "x", we get:
x = (185) / tan(5)
x ≈ 2046.1 feet
Therefore, the length of the line of sight from the ship to Nicole is approximately 2046.1 feet, rounded to the nearest tenth.

Explanation:
You don't need a calculator for this.
Each fraction involves 9 in the denominator. The numerators are the only thing that change. Let x be the numerator.
x/9 = 3.1 can be estimated to x/9 = 3 and that solves to x = 27
The numerator is around 27.
If x = 26, then 26/9 is slightly smaller than 3If x = 27, then 27/9 is exactly 3If x = 28, then 28/9 is slightly larger than 3Choices A,B,C are ruled out since the numerators are smaller than 28. The only thing left is choice D.

The first term of a geometric sequence is 7 and the common ratio is -3.
Find the 7th term.
The first term in this sequence is 7 and the common ratio is -3, so the formula for the 7th term, a7, can be written as a7 = 7(-3)6.7 multiplied by -18 is equal to -126, so the 7th term in this geometric sequence is -126.
What are geometric sequences?Geometric sequences are used to represent growth and decay. The common ratio determines whether the sequence is increasing (if r > 1) or decreasing (if 0 < r < 1). When the common ratio is a whole number, such as 2 or 3, the terms in the sequence are whole numbers as well.
Geometric sequences are sequences where each term is found by multiplying the previous term by a fixed number, called the common ratio. In this case, the first term is 7 and the common ratio is -3, so each term is found by multiplying the previous term by -3. This means that the second term is 7(-3) = -21, the third term is -21(-3) = 63, the fourth term is -63(-3) = -189, and so on. By using the formula a7 = ar6 and substituting in the first term and common ratio, the 7th term can be calculated as -126.
The 7th term of a geometric sequence is calculated by using the formula a7 = ar6, where a is the first term and r is the common ratio. The first term in this sequence is 7 and the common ratio is -3, so the formula for the 7th term, a7, can be written as a7 = 7(-3)6. To calculate this, the exponent 6 must be multiplied by -3, giving -18. 7 multiplied by -18 is equal to -126, so the 7th term in this geometric sequence is -126.

The point after 30, 000 km will they first have to change the oil, rotate the tires and replace the wiper blades all at once.
What is Arithmetic Progression?Arithmetic Progression (AP) is a numerical series in which the difference between any two consecutive numbers is a constant value. Arithmetic Sequence is another name for it.
The First term is an "oil change" with a step d = 3000 km;
and, the second term is tire rotation = 10, 000 Km
and, the third term is replacement of wiper blades = 15, 000 Km
Now, we know from the formula of Arithmetic Progression is
= + d(n-1)
So, 15,000 = 10,000 + 10,000 (n-1)
15, 000 = 10,000 + 10, 000n- 10,000
150000 = 10000n
n = 1.5
This means that at the point 15 000 km and all three progressions will not intersect.
Now, We take the second term of the progression as = 30,000 km
So, 30,000 = 10,000 + 10,000 (n-1)
20,000 = 10,000n - 10,000
30, 000 = 10,000n
n= 3
Similarly, check this intersection point for the first progression with a step of d = 3 000 km we get n =9.

Let h(x) = f(x) + g(x). If f(x)=x^3 and g(x)=4x^4, what is h’(1)
Answer:
h'(1) = 19
Step-by-step explanation:
if h(x) = f(x) + g(x), and f(x) = x³ and g(x) = 4x⁴,
then h(x) = (x³) + (4x⁴)
h(x) = x³ + 4x⁴
h'(x) is the derivative of h(x), which = 3x² + 16x³. Thus, h'(1) = 3(1)² + 16(1)³ = 19

Step-by-step explanation:
The rule is to divide 6.
IF: You input 72 & the output is 12:
72/6 = 12
IF: You input 54 & the output is 9:
54/6 = 9
IF: You input 120 & the output is 20:
120/6 = 20
etc.
Therefore, you are dividing 6 each time. The given input is 150. Divide 150 with 6 to find your output:
150/6 = 25
25 would be your output.
