Answer:

Option A is the correct answer.

Step-by-step explanation:

Period of simple pendulum is given by the expression,

            [tex]T=2\pi \sqrt{\frac{l}{g}}[/tex]

Where l is the length of pendulum, g is acceleration due to gravity.

Here given for Venus

         Period, T = 2.11 s

        Length of pendulum, l = 1 m

     We need to find acceleration due to gravity, g

Substituting

            [tex]2.11=2\pi \sqrt{\frac{1}{g}}\\\\\sqrt{g}=\frac{2\pi}{2.11}\\\\g=8.87m/s^2[/tex]

Acceleration due to gravity of Venus = 8.9 m/s²

Option A is the correct answer.

Answer:

25

Step-by-step explanation:

If the mean of the temperatures in the chart is 24° with standard deviation of 4º, there has been 25 years within one  standard deviation of the mean.

27° is the temperature value that is within one standard deviation of mean.

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Given

Mean of the temperatures in the chart [tex]\mu[/tex] [tex]\mew[/tex]= 24°

Standard deviation [tex]\sigma[/tex] = 4º

The lower and upper bound for temperature within one standard deviation of the mean is given as:

Lower bound =  [tex]\mu[/tex] -  [tex]\sigma[/tex] = 24° - 4º =  20°

Thus, the lower bound is  = 20°

Upper bound =  [tex]\mu[/tex] + [tex]\sigma[/tex] = 24° + 4º =  28°

Thus, the upper bound is  = 28°

Now, the temperature value between (Lower bound, Upper bound) that is (20°, 28°) is said to be within one standard deviation of the mean.

Hence, 27° is the temperature value that is within one standard deviation of mean.

Step-by-step explanation:

The difference of squares is x^2 - y^2 = (x-y) (x+y)

36a^2 = (6a)^2

9 = (3)^2

(6a -3) (6a+3)

This is the difference of squares

The correct answer is a. Yes, 36a² - 9 is a difference of squares

The given expression is [tex]36a^2 - 9[/tex].

To determine if it is a difference of squares we need to identify if it can be written in the form of a² - b², which factorizes to (a + b)(a - b).

We can see that

36a² is a perfect square because it can be written as (6a)² and 9 is also a perfect square because it can be written as 3². Therefore, we can rewrite the expression as:

[tex]36a^2 - 9 = (6a)^2 - 3^2[/tex]

Thus, we can see that the expression 36a² - 9 is a difference of 6a square and 3 square. So, it is indeed a difference of squares.

Answer: a. Yes, 36a² - 9 is a difference of squares

Step-by-step explanation:

Lets say x=1

y: 3(1)+1=4

x: 4(1)-1=3

Final answer:

The correct option is (D) (2,7). To solve the system of equations, set them equal to each other and solve for x, which is 2, and then substitute x back into either equation to find y, which is 7. Hence, the intersection point is (2, 7).

Explanation:

To find the solution to a system of equations when graphed, you look for the point where the two lines intersect. The given equations are y=3x+1 and y=4x-1.

Since both equations equal y, you can set them equal to each other to find the point of intersection:

3x + 1 = 4x - 1.

To solve for x, subtract 3x from both sides:

1 = x - 1.

Then, add 1 to both sides to isolate x:

x = 2.

To find the corresponding y value, substitute x into one of the original equations, let's use the first one:

y = 3(2) + 1,

which simplifies to y = 6 + 1 = 7.

Therefore, the solution to the system of equations and the point of intersection is (2, 7).

Answer:

Step-by-step explanation:

To find the reference angle for an angle given in degrees, you can follow these steps:

Determine the absolute value of the given angle.

If the angle is more significant than 360 degrees, subtract the largest possible multiple of 360 degrees to bring it within the range of 0 to 360 degrees.

If the angle is negative, convert it to a positive angle by adding 360 degrees.

The reference angle is the acute angle formed between the terminal side of the angle and the x-axis.

Let's apply these steps to the given angle t = -216 degrees:

Absolute value of -216: | -216 | = 216 degrees

216 degrees is already within the 0 to 360-degree ranges, so there is no need to subtract any multiple of 360 degrees.

Since the angle is negative, convert it to a positive angle: 216 degrees

The reference angle is the acute angle formed with the terminal side of the angle, which is 216 degrees.

Therefore, the reference angle for t = -216 degrees is 216 degrees.

The correct answer would be option A, 21.37

Step-by-step explanation:

In order to find out the percentage change of price of a product, either increase of decrease, that is found by finding the change in the price and then divide it by the base price and then finding the percentage of that price. The whole process is as follows:

Original price of iPod: $210.95

New Price of iPod: $165.88

Decrease in the price of iPod: 210.95-165.88= 45.07

Now dividing decreased price with the original price we get:

45.07/210.95=0.213652

Now to find the percentage, we need to multiply it with 100

0.213652*100=21.3652% which is approximately 21.37%

Step-by-step explanation:

10a) To find the exact answer, simply divide the given numbers.

10b) To find the estimated answer, use compatible numbers. We know that any "hundred" number is easily divisible by 5. Therefore, 900/5 = 36.

It is possible for the estimate to be the same as the exact answer.

10a) To find the exact answer, simply divide the given numbers.

10b) To find the estimated answer, use compatible numbers. There is no pattern we can look for, so round to the nearest whole number.

Answer:

x=-1 y= -5

Step-by-step explanation:

y = – x – 6

y = x – 4

Substitute into y  = -x-6 into the second equation

y =x-4

-x-6 = x-4

Add x to each side

-x-6+x =x-4+x

-6 =2x-4

Add 4 to each side

-6+4 =2x-4+4

-2 = 2x

Divide by 2

-2/2 =2x/2

-1 = x

Now find y

y =-x-6

y = -(-1) -6

y =1-6

y = -5

Answer:

x = -1

y = -5

Step-by-step explanation:

Given:

We'd take one of the equations above and substitute it with the y variable:

x - 4 = -x - 6

-x is smaller, so we add x in both sides:

2x - 4 = -6

Add 4 in both sides:

2x = -2

Divide 2 in both sides:

x = -1

Solve for y

y -(-1) - 6 = -5

y = -5

Our answer is x = -1, y = -5

Explanation:

The type of model that best fits the situation of a $500 raise in a salary each year is a linear model.

In a linear model, the dependent variable changes a constant amount for constant increments of the independent variable.

In the given case, the dependent variable is the salary and the independent variable is the year.

You may build a table to show that for increments of 1 year the increments of the salary is $500:

Year         Salary        Change in year         Change in salary

2010           A                           -                                       -

2011           A + 500     2011 - 2010 = 1          A + 500 - 500 = 500

2012          A + 1,000   2012 - 2011 = 1          A + 1,000 - (A + 500) = 500

So, you can see that every year the salary increases the same amount ($500).

In general, a linear model is represented by the general equation y = mx + b, where x is the change of y per unit change of x, and b is the initial value (y-intercept).              

In this case m = $500 and b is the starting salary: y = 500x + b.

Let r = amount customer gets back

r = 1000 - (1000)(0.03)

r = 1000 - 30

For this case we have the following polynomial:

We must find the greatest common factor of the terms of the polynomial.

The GCF of the coefficients is given by:

[tex]24 = 3 * 8\\40 = 5 * 8[/tex]

Then we look for the GFC of the variables:

We have then:

[tex]a ^ 6 = a ^ 3a ^ 3\\a ^ 3 = a ^ 3[/tex]

Finally rewriting we have: [tex]-24a ^ 6b ^ 4-40a ^ 3 = -8a ^ 3 (3a ^ 3b ^ 4 + 5)[/tex]

the complete factored form of the polynomial is:

To solve (sin(x))^2 = 1/36, we find the arcsine of ±1/6. The solutions are sin⁻¹(1/6), π - sin⁻¹(1/6), 2π - sin⁻¹(1/6), and π + sin⁻¹(1/6) within the interval [0,2π].

To solve the equation (sin(x))^2 = 1/36 in the interval [0,2π], we first take the square root of both sides to get sin(x) = ±1/6. The sine function oscillates between -1 and 1 every 2π radians, which means that we are looking for angles where the sine value is ±1/6.

To find the specific angles, we use the arcsine function or inverse sine function. The principal value of sin⁻¹(1/6) gives us one of the solutions, and considering the symmetry of the sine function, the other solutions can be found in the second and fourth quadrants, where the sine function is positive and negative, respectively.

The solutions to sin(x) = 1/6 in the interval [0,2π] are x = sin⁻¹(1/6) and x = π - sin⁻¹(1/6). For sin(x) = -1/6, the solutions are x = 2π - sin⁻¹(1/6) and x = π + sin⁻¹(1/6). Thus, the solutions to the original equation (sin(x))^2 = 1/36 within [0,2π] are sin⁻¹(1/6), π - sin⁻¹(1/6), 2π - sin⁻¹(1/6), and π + sin⁻¹(1/6), all of which can be calculated to find the exact values.
