Given is the special right triangle.

It is a 45° isosceles right triangle. It has a property that the hypotenuse is √2 times the leg.

We have a hypotenuse of 28 units, so the leg is:

Answer:

14√2

Step-by-step explanation:

Here we need to find out the value of "x" in the given right angled triangle, here we can make use of trigonometric ratios to find out the value of x .

In a right angled triangle, sine is defined as the ratio of perpendicular and hypotenuse . With respect to angle 45° , x is the perpendicular and 28 is hypotenuse (side opposite to 90° ) .

So we have;

sin45° = x/28

1/√2 = x/28

x = 28*1/√2

x = 14 * (√2)² / √2

x = 14√2

Hence the value of x is 14√2 .

Answer:

s = 10

Step-by-step explanation:

This Triangle is a Right Triangle with two equal sides ( because there are two equal angles )

Pytha. Theorem

A² + B² = C²

since we have two equal sides the A = B = s

then

s² + s² = c²

2s² = c²

2s² = (10sqrt2)²

2s² = 100 x 2

2s² = 200

s² = 200/2 = 100

s = sqrt ( 100 )

s = 10

Answer:

-21

Step-by-step explanation:

g(x)=3x-3

g(-6)

g=(-6 times 3)-3

g=-18-3

g=-21

g(-6) = - 21

g(x) = 3x - 3

g(-6) = 3(-6) - 3

= - 18 - 3

= - (18 + 3)

= - 21

Answer: $5400

Step-by-step explanation:

x =  amount raised so far

13500 - x = amt. still needed

x/3 = (13500 - x)/2

2x = 3(13500 - x)

2x = 40500 - 3x

5x = 40500

x = 40500/5 = 8100 (amt. raised so far)

13500 - 8100 = 5400 (amt. still needed)

18.8 fleck dickon Dunn dream fun deep

Answer:

Benford’s law states that the probability that a number in a set has a given leading digit, d, is

P(d) = log(d + 1) - log(d)  

The division property of logarithm should be use to make it as a single logarithm  

P(d) = log ( (d + 1)/ d)  

So the probability that the number 1 is the leading digit is

P(1) = log ( ( 1+1)/ 1)

P(1) = log ( 2)

P(1) = 0.301

Step-by-step explanation:

Answer:

Use the quotient property to rewrite the expression. Write the difference of logs as the quotient log((d+1)/d). Substitute 1 for d to get log(2).  Since log(2) = 0.30, the probability that the number 1 is the leading digit is about 30%.

It is not possible to find a combination using addition and multiplication of the given single-digit numbers that totals exactly 100 while keeping the same order.

To combine the single-digit numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 using only addition and multiplication so that they total 100 while keeping the same order, we can form the following expression:

1 + 2 + 3 + 4 + 5 + 6 + 78 + 9

In this expression, we group the numbers 7 and 8 together to form 78. Then, we add all the other numbers from 1 to 6 and the number 9. Adding them up, we get:

1 + 2 + 3 + 4 + 5 + 6 + 78 + 9 = 108

Unfortunately, the sum obtained from this expression is 108, not 100 as required.

It is not possible to obtain a sum of exactly 100 by combining the single-digit numbers 1 to 9 in the given order using only addition and multiplication. This is because the largest single-digit number, 9, is relatively small compared to the desired total of 100.

Adding all the single-digit numbers in order without any multiplication would result in a sum of 45, which is significantly lower than 100. Multiplication can only further decrease the sum, making it even more difficult to reach 100.

Answer:

120 - 14 = 106

Step-by-step explanation:

7 x 2 = 14

10 x 12 = 120 therefore you,

120 - 14 = 106

The area of the shaded region is 106 m².

We have,

The area of the rectangle:

= length x width

From  the figure,

Bigger rectangle dimensions:

Length = 12 m

Width = 10 m

Smaller rectangle dimensions:

Length = 7 m

Width = 2 m

Now,

The shaded region.

= Area of the bigger rectangle - Area of the smaller rectangle

= 12 x 10 - 7 x 2

= 120 - 14

= 106

Answer:

Step-by-step explanation:

To dilate the square by a factor of 1111 from the origin, we need to multiply each coordinate by 1111.

The coordinates of point C are (8,8). So, to find the coordinates of point C' after dilation, we can simply multiply each coordinate by 1111:

x-coordinate of C' = 1111 * 8 = 8888

y-coordinate of C' = 1111 * 8 = 8888

Therefore, the coordinates of point C' are (8888, 8888).

√x+3 is an increasing function, the minimum value is L4 and the maximum value is R4.

Since we are given 4 subintervals, the width of each subinterval is:

Δx = (b - a) / n = (1 - (-1)) / 4 = 1/2

where a = -1 and b = 1 are the endpoints of the interval.

Now, L4 = f(-1)Δx + f(-1/2)Δx + f(0)Δx + f(1/2)Δx

= √2/Δx + √3/Δx + √3/Δx + √4/Δx

= (2√2 + 2√3 + 2√4) / Δx

= 10(2√2 + 2√3 + 2√4)

and, the right endpoint Riemann sum,

R4 = f(-1/2)Δx + f(0)Δx + f(1/2)Δx + f(1)Δx

= √3/Δx + √3/Δx + √4/Δx + √5/Δx

= (2√3 + 2√4 + 2√5) / Δx

= 4(√3 + 2√4 + √5)

Since √x+3 is an increasing function, the minimum value is L4 and the maximum value is R4.

Venn diagrams are charts that are used to visually represent relationships between sets, operations on those relationships, and set relationships. The Venn diagram, which uses circles that are overlapped, intersected, and not intersected to depict the relationship between sets, was created by John Venn. A set diagram or a logic diagram is another name for a Venn diagram, which shows a variety of set operations such the intersection, union, and difference of sets.

Additionally, it can be used to set items. a depiction of each relationship between several sets. Any closed figure, such as a circle or a polygon (square, hexagon, etc.), can be used to represent a Venn diagram. However, each group is typically represented as a circle.

Just divide all the fractions as you normally would to solve a division problem. Another way to make it easier is if you have a whole number than put that whole number in front of the decimal first then solve the division problem.

The value of the angle θ is approximately 24.2 degrees to 1 decimal place.

In a right-angled triangle, the tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. Given that tan θ = 23/52, we can find the value of the angle θ.

To find the value of θ, we can use the inverse tangent or arctan function. Taking the inverse tangent of both sides of the equation, we have:

θ = arctan(23/52)

Using a calculator or trigonometric tables, we can evaluate the inverse tangent of 23/52. The result is approximately 24.2 degrees.

Note that in the context of a right-angled triangle, the tangent function is defined for acute angles (less than 90 degrees). Since 0 degrees is the smallest possible angle, it is considered an acute angle in this case.
