Roberta jogs 3 laps the first day, 5 laps the second day, 7 laps the third, and so on. On which day will Roberta jog 13 laps if the pattern continues.
It seems that she runs two more laps each day, so:
day 1- 3
day 2- 5
day 3- 7
day 4- 9
day 5- 11
day 6- 13
simple patterns baby
Final answer:
Roberta will jog 13 laps on the sixth day of her jogging routine, following the arithmetic sequence of adding 2 laps each day, starting with 3 laps on the first day.
Explanation:
The student is asking about a pattern in which Roberta jogs an increasing number of laps each day, with the sequence starting at 3 laps and increasing by 2 laps each subsequent day. To determine on which day Roberta will jog 13 laps, we can identify this as an arithmetic sequence with a common difference of 2. The first day is 3 laps, the second day is 5 laps, and this pattern continues. Following this sequence, the number of laps jogged by Roberta each day is:
Day 1: 3 lapsDay 2: 5 lapsDay 3: 7 lapsDay 4: 9 lapsDay 5: 11 lapsDay 6: 13 lapsThus, Roberta will jog 13 laps on the sixth day, if the pattern continues.
Find a numerical value if one trigonometric function of x if tan2x-sin2x/sin2x=5
Answer:
The values of x that satisfy the given equation are:
x1 = 1.183 + nπ
x2 = -1.183 + nπ
Step-by-step explanation:
Given tan²x - sin²x/sin²x = 5
Simplifying this, we have
tan²x - 1 = 5
Adding 1 to both sides, we have
tan²x = 6
Because tan²x = (tanx)², we can write as
(tanx)² = 6
Taking square roots of both sides, we have.
tanx = ±√6
x = arctan(±√6) + nπ
≈ 1.183 + nπ or -1.183 + nπ
The question asks to find a trigonometric value for x given a trigonometric equation. Clear solution steps cannot be provided due to ambiguity in the equation's presentation. Normally, one would use trigonometric identities or methods like Newton's method to find x.
Explanation:The question requires us to find a numerical value of one trigonometric function of x given the equation tan2x - sin2x/sin2x = 5. Although the provided reference text contains various trigonometric contexts, it lacks direct relation to solving the given equation.
In order to solve for x, one would typically aim to manipulate the equation into a standard trigonometric identity or apply techniques such as Newton's method if handling a more complex algebraic expression involving trigonometric functions.
To tackle the given trigonometric equation, we would ideally express tan2x in terms of sin2x and cos2x using the identity tan2x = sin2x/cos2x, thus simplifying the equation and allowing us to isolate and solve for x.
Unfortunately, there is an ambiguity in the equation presented in the question (lack of clear parentheses), and so a definitive solution cannot be provided without clarification.

Find the equation of the tangent to the circle x²+y²=169 at the point (5,12)
Answer:
12y + 5x = 169
Step-by-step explanation:
Differentiate wrt x
2x + 2y(dy/dx) = 0
dy/dx = -x/y
At (5,12)
m = -5/12
y = (-5/12)x + c
12 = -25/12 + c
c = 169/12
y = (-5/12)x + 169/12
12y + 5x = 169
Answer:
y = [tex]\frac{-5}{12}[/tex] x +17
Step-by-step explanation:
We'll have to use calculus and differentiating to solve this.
Differentiate the given equation with respect to x:
x^2 + y^2 = 169
2x + 2y * (dy/dx) = 0
Solve for dy/dx:
dy/dx = -x/y
Now, what this derivative means is actually the slope of the tangent line at the point (x, y).
Substituting 5 in for x and 12 in for y, we get:
dy/dx = -5/12
So, the slope is -5/12
Now, we have a slope (m = -5/12) and a point (5,12), so we can write an equation in point-slope form, which is: [tex]y-y_1=m(x-x_1)[/tex], where (x_1, y_1) is the point and m is the slope. So, we have:
y - 12 = [tex]\frac{-5}{12}[/tex] (x - 12)
We can then solve for y (if you want): y = [tex]\frac{-5}{12}[/tex] x +17.

Marissa is painting her rectangular patio, with the exception of a bench that does not need to be painted:
Write an equation to determine the area, A, of the patio that will be painted.
A = (x + 18)(x + 35)
A = (x + 15)(x + 25) + 30
A = (x + 5)(x + 22)
A = (x + 25)(x + 15) − 30
Answer:
A = (x + 25)(x + 15) - 30
Step-by-step explanation:
This question is not complete without a figure; find the figure attached.
Marissa is painting a regular patio with dimensions as
Length = (x + 25) units
Width = (x + 15) units
Area of this rectangular patio = Length × Width
Area = (x + 25)(x + 15) unit²
She has to paint the patio except the bench that does not need to be painted.
Dimensions of the rectangular bench,
Length = 10 units
Width = 3 units
Area of the bench = 10×3 = 30 units²
Area of the patio to be painted = Area of patio - Area of bench
A = (x + 25)(x + 15) - 30

To translate 2 left, subtract 2 from every x-value.
To translate 6 up, add 6 to every y-value.
__
W' = W +(-2, 6) = (4-2, 8+6)
W' = (2, 14)
__
X' = X +(-2, 6) = (3-2, -2+6)
X' = (1, 4)

Y' = Y +(-2, 6) = (6-2, 5+6)
Y' = (4, 11)
With a tailwind, a aircraft can fly 360 miles in 3 hrs. Against this same wind, the aircraft can fly the same distance in 4hrs. Find the effect of the wind and the average of the aircraft
Answer:
15mph
Step-by-step explanation:
360 divide by 3 = 120
360 divide by 4 = 90
120 - 90 = 30
30 divide by 2 (cause boosting speed and drag) = 15
so let's check
120-15=105
105+15=120
105-15= 90
so the answer's 15.
To find the effect of the wind and the average speed of the aircraft, set up a system of equations and solve them simultaneously. The effect of the wind is a speed of 15 mph and the average speed of the aircraft is 105 mph.
Explanation:To find the effect of the wind and the average speed of the aircraft, we can set up a system of equations. Let's denote the speed of the aircraft as 'a' and the speed of the wind as 'w'. With a tailwind, the aircraft can fly 360 miles in 3 hours, so we have the equation 360 = (a + w) * 3. Against the wind, the aircraft can fly the same distance in 4 hours, so we have the equation 360 = (a - w) * 4.
Now, we can solve these equations simultaneously to find the values of 'a' and 'w'. Multiplying the first equation by 4 and the second equation by 3 gives us 1440 = (a + w) * 12 and 1080 = (a - w) * 12. Subtracting the second equation from the first equation eliminates the 'w' term, giving us 1440 - 1080 = (a + w) * 12 - (a - w) * 12. Simplifying further, we get 360 = 24w. Dividing both sides by 24 gives us w = 15. Substituting this value back into one of the original equations, we can find the value of 'a'. Using the equation 360 = (a + 15) * 3, we can solve for 'a' to get a = 105.
Therefore, the effect of the wind is a speed of 15 mph and the average speed of the aircraft is 105 mph.

The angle between the ground and the rope = 25°
Length of the rope = 34.5 ft.
To find :
The height of the tree.
We can use the sine to calculate the height of the tree.
sin 25° = t/34.5
sin 25° = 0.42
sin 25° = t/34.5
0.42 = t/34.5
t = 0.42 x 34.5
t = 14.5 ft.
