Answer:

c = 11.3 yards

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here A = 416.955, h = 20.9, a = 28.6 and b = c, thus

[tex]\frac{1}{2}[/tex] × 20.9 × (28.6 + c) = 416.955, that is

10.45(28.6 + c) = 416.955 ( divide both sides by 10.45 )

28.6 + c = 39.9 ( subtract 28.6 from both sides )

c = 11.3 yards

Answer:

-1215.

Step-by-step explanation:

For a geometric sequence:

nth term = a1 r^(n-1)

The first term a1 = 5 and the common ratio r  = -15/5 = -3.

So 6th term = 5 * (-3)^(6-1)

=  5 * (-3)^5

= -1215.

The 6th term in this geometric sequence should be considered as the -1215.

The following formula should be used for the same.

nth term = [tex]a_1\ r^{(n-1)[/tex]

Here,

The first term a1 = 5

and the common ratio r  = [tex]-15/5[/tex]= -3.

So 6th term should be

[tex]= 5 \times (-3)^{(6-1)}[/tex]

[tex]= 5 \times (-3)^5[/tex]

= -1215

Hence, The 6th term in this geometric sequence should be considered as the -1215.

Answer:

9

Step-by-step explanation:

a triangle is bacicly half of a rectangle so 3 x 6 is 18 but since it's just half, you divide by 2 and you get 9!

Step-by-step explanation:

Phytagoras Theorem :

c² = a² + b²

c² = 3² + 6²

c² = 9 + 36

c² = 45

c = √45

So, the exact length og the third side is √45

Answer:

A)

x + 7 < 5

Shows inequality

The correct inequality that represents the solutions on the given number line is C) [tex]\( x - 5 > 2 \).[/tex]

To find the correct inequality, we need to determine which one corresponds to the shaded portion of the number line. The shaded portion indicates the set of all [tex]\( x \)[/tex] values that satisfy the inequality.

Let's analyze each option:

A) [tex]\( x + 7 \leq 5 \)[/tex]

If we solve this inequality, we get:

[tex]\( x \leq 5 - 7 \)[/tex]

[tex]\( x \leq -2 \)[/tex]

This inequality would be represented by a number line shaded to the left of -2, including -2 itself. This does not match the given number line, which is shaded to the right of a point.

B) [tex]\( x + 3 \geq 1 \)[/tex]

Solving this inequality, we get:

[tex]\( x \geq 1 - 3 \)[/tex]

[tex]\( x \geq -2 \)[/tex]

This inequality would be represented by a number line shaded to the right of -2, including -2 itself. However, the inequality sign in the question is non-inclusive, which means -2 itself should not be shaded. This does not match the given number line, which has a shaded circle at the starting point of the shaded region, indicating inclusivity.

C) [tex]\( x - 5 > 2 \)[/tex]

Solving this inequality, we get:

[tex]\( x > 2 + 5 \)[/tex]

[tex]\( x > 7 \)[/tex]

This inequality would be represented by a number line shaded to the right of 7, not including 7 itself. This matches the given number line, which shows the shaded region starting just to the right of 7 (indicated by an open circle at 7).

D) [tex]\( x - 1 \leq 1 \)[/tex]

Solving this inequality, we get:

[tex]\( x \leq 1 + 1 \)[/tex]

[tex]\( x \leq 2 \)[/tex]

This inequality would be represented by a number line shaded to the left of 2, including 2 itself. This does not match the given number line, which is shaded to the right of a point and has an open circle at the starting point of the shaded region.

Therefore, the correct answer is C)[tex]\( x - 5 > 2 \)[/tex], as it accurately describes the shaded region on the given number line.

Answer:

d) [tex]y=-\frac{1}{2} (x-3)^{2} -4[/tex]

Step-by-step explanation:

When you reflect an equation the slope is the opposite (if the slope is positive it'll be negative when reflected)

The slope is [tex]\frac{1}{2}[/tex] and when it is reflected it is [tex]-\frac{1}{2}[/tex]

When you shift something to the right you add [tex](x-3)^{2}[/tex]

The slope between the points (0, –5) and (–9,1) is -2/3, which is found using the slope formula. Positive slopes rise, negative slopes fall, and zero slopes are horizontal lines.

To find the slope of a line passing through two points (0, –5) and (–9,1), we use the formula for the slope (m), which is m = (y₂ - y₁) / (x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.

Substituting the given points into the formula, we get m = (1 - (-5)) / (-9 - 0), which simplifies to m = (1 + 5) / (-9), and further simplifies to m = 6 / (-9), resulting in a slope of m = -2/3.

Regarding slope and its characteristics on a graph, a positive slope means the line rises as it moves from left to right, a negative slope means the line falls as it moves from left to right, and a zero slope indicates a horizontal line.

Answer:

V=250(2d)

Step-by-step explanation:

The equation representing the value of a bond doubling every decade is

V = 2d(250).

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A bond is initially bought for $250 and it doubles in value every decade.

Let, 'v' be the value of the bond at any given time and 'd' be the number of decades.

Therefore, The equation that represents this situation is,

V = 2d(250).

Answer:

x = 26

Step-by-step explanation:

The three angles form a straight line, so they will sum to 180

4x - 8  + 34  + 76- x = 180

Combine like terms

3x+ 102 = 180

Subtract 102 from each side

3x+102-102 = 180-102

3x= 78

Divide each side by 3

3x/3 = 78/3

x = 26

There is a probability of 9.3% that the normal distribution data value is between 27 and 28

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (raw score - mean)/standard deviation

Given that:

mean of 26 and a standard deviation of 4, For:

For x = 27:

z = (27 - 26) / 4 = 0.25

For x = 28:

z = (28 - 26) / 4 = 0.5

P(0.25 < z < 0.5) = P(z < 0.5) - P(z < 0.25) = 0.6915 - 0.5987 = 0.093
