The length of a rectangle is twice as long as it’s width. it’s perimeter is 18 in. How long and how wide is the rectangle?
Answer: Let's start by using algebra to solve the problem.
Let's call the width of the rectangle "w". Then we know that the length of the rectangle is twice the width, or "2w".
The formula for the perimeter of a rectangle is:
P = 2l + 2w
where P is the perimeter, l is the length, and w is the width.
We know that the perimeter is 18 inches, so we can substitute the values we have:
18 = 2(2w) + 2w
Simplifying:
18 = 4w + 2w
18 = 6w
Dividing both sides by 6:
w = 3
So the width of the rectangle is 3 inches.
To find the length, we can use the fact that it is twice the width:
l = 2w = 2(3) = 6
So the length of the rectangle is 6 inches.
Therefore, the rectangle is 6 inches long and 3 inches wide.

The radius of a quarter circle is 1 yard. What is the quarter circle's perimeter?
The perimeter of the quarter circle with radius 1 yard is approximately 2.57 yards.
To find the perimeter of a quarter circle, we need to add up the lengths of its curved edge and its straight edge.
In this case, the curved edge is a quarter of a circle with radius 1 yard. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle. Since we only need a quarter of the circumference, we can divide the formula by 4:
C = (2πr)/4
Substituting r = 1, we get:
C = (2π(1))/4
C = π/2
Therefore, the curved edge of the quarter circle has a length of π/2 yards. The straight edge of the quarter circle is simply the radius, which is also 1 yard.
So the perimeter of the quarter circle is the sum of the curved edge and the straight edge:
Perimeter = (π/2) + 1
Using 3.14 for π and adding the two terms, we get:
Perimeter ≈ 2.57 yards

Games A group of friends tries to keep a beanbag from touching the ground.
On one kick, the beanbag's height can be modeled by h = -161² + 14t + 2, where h
is the height in feet above the ground and t is the time in seconds. Find the time it
takes the beanbag to reach the ground.
The time it takes for the beanbag to reach the ground is t = 1 second.
What is quadratic equation ?
A quadratic equation is a expression of the form ax^{2} + bx + c = 0, where x is the variable, and a, b, and c are constants. It is a type of second-degree polynomial equation, which can be solved using various methods, including factoring, completing the square, and using the quadratic formula
We know that the beanbag will touch the ground when its height, h, equals zero. Therefore, we can set the equation for h equal to zero and solve for t:
h = -16t² + 14t + 2
0 = -16t² + 14t + 2 (substitute h=0)
0 = -8t² + 7t + 1 (divide both sides by 2)
0 = (t-1)(-8t-1) (factor the quadratic)
So, either t - 1 = 0 or -8t - 1 = 0. Solving for t in each case, we get:
t - 1 = 0 => t = 1
-8t - 1 = 0 => t = -1/8
The negative value of t doesn't make sense in this context, since time cannot be negative. Therefore, the time it takes for the beanbag to reach the ground is t = 1 second.

(4) 4.3.2 Solve the two equations you formed in 4.3.1 using Cramer’s rule to find the number of coins of each value. (6)
There are 17 one-dollar coins and 19 two-dollar coins in the machine.
How did we arrive at these values?4.3.1 Model the statement into two linear equations by letting the number of one-dollar coins to be x and the number of two-dollar coins to be y:
Let x be the number of one-dollar coins and y be the number of two-dollar coins in the machine. Then we can form the following two linear equations:
Equation 1: x + y = 36 (total number of coins)
Equation 2: 1x + 2y = 55 (total value of coins)
4.3.2 Solve the two equations you formed in 4.3.1 using Cramer’s rule to find the number of coins of each value:
To solve the two equations using Cramer's rule, we need to write them in matrix form:
| 1 1 | | x | | 36 |
| | x | | |
| 1 2 | | y | | 55 |
Using Cramer's rule, we first calculate the determinant of the coefficient matrix:
D = | 1 1 |
| 1 2 |
D = (1 x 2) - (1 x 1) = 1
Then we replace the first column of the coefficient matrix with the constants from the right-hand side of the equations:
Dx = | 36 1 |
| 55 2 |
And calculate the determinant of this matrix:
Dx = (36 x 2) - (55 x 1) = 17
Similarly, we replace the second column of the coefficient matrix with the constants from the right-hand side of the equations:
Dy = | 1 36 |
| 1 55 |
And calculate the determinant of this matrix:
Dy = (1 x 55) - (1 x 36) = 19
Finally, we can calculate the values of x and y using the formulas:
x = Dx / D = 17 / 1 = 17
y = Dy / D = 19 / 1 = 19
Therefore, there are 17 one-dollar coins and 19 two-dollar coins in the machine.

Would the interval found in part c increase, decrease, or remain the same if fewer than 95 people were surveyed? justify your answer
The confidence interval would increase because with fewer people, the margin of error would be larger.
The confidence interval found in part c would increase if fewer than 95 people were surveyed. This is because the margin of error is calculated using the sample size; the smaller the sample size, the larger the margin of error. The margin of error dictates the range of values that the population parameter is likely to fall within. Therefore, if fewer people are surveyed, the margin of error would increase, resulting in a wider confidence interval. This means that the interval from part c would no longer be valid if the sample size decreased, and a new interval with a larger range would need to be calculated.

1. Evaluate each expression. Give your answer in radians:
i. Without using a calculator: cos⁻¹(−√2/2)Firstly, let us discuss the meaning of the inverse cosine function. The inverse cosine function is the angle (in radians) that corresponds to the cosine value of the input angle. The inverse cosine function returns values in the range [0, pi].cos⁻¹(−√2/2) can be read as "what angle has a cosine of -√2/2?"In a right-angled triangle with angle θ, adjacent is -1, hypotenuse is √2, and opposite is -1. Therefore, we can write the cosine ratio as adjacent over hypotenuse or -1/√2. Let us now solve for θ using the formula for cosine:cosθ = adjacent/hypotenusecosθ = -1/√2θ = cos⁻¹(-1/√2)The exact value of cos⁻¹(-1/√2) is π/4. Therefore, cos⁻¹(-√2/2) = π/4.
ii. Use a calculator: sin^-1(-0.512)As previously mentioned, the inverse sine function is the angle (in radians) that corresponds to the sine value of the input angle. The inverse sine function returns values in the range [-π/2, π/2].sin⁻¹(-0.512) can be read as "what angle has a sine of -0.512?" To find this value, we use a calculator. First, we press the "sin⁻¹" button or "2nd" + "sin" button. Then, we enter the value we want to find, which is -0.512. The final answer is -0.529. Therefore, sin⁻¹(-0.512) = -0.529.

Kusum brought 50 glasses for Rs 1500 out of which 4 were broken. If she sold
the rest of the glasses for Rs 35 each, how much profit or loss precent did she bear?
Answer: 7.33%
Step by step explanation:
CP of 50 glasses = Rs. 1500
4 glasses broken
Glass remaining = 50 - 4 = 46
Selling price of 1 glass = Rs 35
SP of 46 glass = 46 x 35 = Rs 1610
Profit = SP - CP = 1610 - 1500 = 110
Profit percentage,
= Profit/CP x 100%
= 110/1500 x 100%
= 7.33%
The cost price of 50 glasses = Rs.1500
The remaining glasses = 46
The Selling price of remaining glasses = 46 × 35
=Rs. 1610
Now
Profit = 1610 - 1500

If PA= 8 and PB = 4, what is the length of BC?
The length of BC is 6 units.
Describe Tangent?In geometry, the tangent is commonly used to describe the relationship between a circle and a straight line. A tangent line to a circle is a line that intersects the circle at exactly one point. This point of intersection is called the point of tangency. The tangent line is perpendicular to the radius of the circle at the point of tangency.
By the tangent-secant theorem, we have:
PB^2 = PA(PA + AB)
where AB is the length of the tangent segment from point A to the point of intersection of the secant with the circle.
Substituting the given values, we get:
4^2 = 8(8 + AB)
Simplifying and solving for AB, we get:
16 = 64 + 8AB
8AB = -48
AB = -6
Since AB is a length, it must be positive, so we take the absolute value:
AB = 6
Now we can use the secant-tangent theorem to find the length of BC:
PC(PC + BC) = PB^2
Substituting the given values and using the fact that PC = PA = 8, we get:
8(8 + BC) = 4^2
64 + 8BC = 16
8BC = -48
BC = -6
Again, since BC is a length, it must be positive, so we take the absolute value:
BC = 6
Therefore, the length of BC is 6 units.
