Help me find the area of the regular polygon!!

The required overall translation is T<−9,−5>(ABC). The correct answer would be option B.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

Starting with triangle ABC, we first apply the transformation T<−5,−3>, which means each vertex of the triangle is shifted 5 units to the left and 3 units down. So the triangle becomes A'B'C'.

Next, we apply the transformation T<−4,−2> to triangle A'B'C', meaning that each vertex is shifted 4 units to the left and 2 units down.

To find the overall effect of these two transformations, we can think of the second transformation as shifting the entire triangle produced by the first transformation.

In other words, we're combining the effects of the two transformations by adding the translations together.

So, the overall translation is T<−5 + −4, −3 + −2> = T<−9,−5>,

Thus, the correct answer would be option B: T<−9,−5>(ABC).

The correct answer is c. 750

Step-by-step explanation:

if the shops makes 25 dozen in two days that makes it 300 cupcakes In two days because 1 dozen is 12 cupcakes, so you will see that they make 50 dozen in 4 days which is 600 then you know he/she is going to make half of the 25 dozen on the 5th day so you will take half of 300 which is 150 and add it all together, so will get 300+300+150= 750 as your answer.

The investments are $ 4000 and $ 3000 in the respective accounts

The mathematical field of algebra assists in the depiction of problems or conditions as mathematical statements. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.

In the given question,

x = amount invested at 10 %

( 7000 - x ) = amount invested at 11 %

The total interest was $730 :

.10 (x) + .11 (7000-x) = 730

0.1 x + 770 - 0.11 x = 730

0.01 x = 40

x = 4000

Therefore, the amount invested in an account that pays 10 % per year is $ 4000.

Hence ,  the amount invested in an account that pays 11 % per year is

= ( 7000 - x ) = 7000 - 4000 = $ 3000.

The sample variance and standard deviation are given as follows:

Variance = 87.22 %.

Standard deviation = 9.34%.

To obtain the variance and the standard deviation first, we must obtain the mean, which is given by the sum of all observations divided by the number of observations, hence:

Mean = (77.1 + 82.9 + 90 + 91.3 + 81.9 + 83.3 + 84.9 + 82.5 + 84.6)/10

Mean = 75.85.

Then we must obtain the sum of the differences squared between each observation and the mean, as follows:

(77.1 - 75.85)² + (82.9 - 75.85)² + (90 - 75.85)² + (91.3 - 75.85)² + (81.9 - 75.85)² + (83.3 - 75.85)² + (84.9 - 75.85)² + (82.5 - 75.85)² + (84.6 - 75.85)² = 784.9825

The sample variance is given by the above sum divided by one less than the sample size, hence:

Variance = 784.9825/9

Variance = 87.22 %.

The standard deviation is the square root of the variance, hence:

Standard deviation = sqrt(87.22)

The percentage of R90 that will give 90c is 4%

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

1 cent = R0.04

R1 = 1/0.04

R 90 = 90/0.04 = 2,250c

x/100 × 2250 = 90

Angles are measured in degrees, with a full circle being 360°, and can be thought of as the amount of rotation that two straight lines or planes undergo.

The class definition of angle changed from a collection of ambiguous expressions, such as “the measurement of all the sides,” “the place where lines meet,” and “the corner of a shape or anything,” to

The equation below can be set up to calculate this.

Tan(angle) = 80 ft / (200 ft – 4 ft)

Solving for the angle, we get:

angle = tan-1(80 ft / 196 ft (ca. 60 m))

angle = tan-1(0.408163265)

Step-by-step explanation:

The number of inches Sami is taller to his younger sister as per their respective given heights is equal to 9 inches.

Height of Sami in feet and inches is equal to 5 feet 8 inches

Height of Sami's younger sister is equal to 4 feet 11 inches

Convert all height into inches we get,

1 feet = 12inches

5 feet = 5 × 12 inches

          = 60 inches

4 feet = 4 × 12 inches

          = 48 inches

Number of inches Sami's is taller than his younger sister is equal to

= ( 5 feet 8 inches ) - ( 4 feet 11 inches )

= ( 60 + 8 ) inches - ( 48 + 11 ) inches

= 68 inches - 59 inches

The solution of the inequality is -4≤x<7. Therefore, option D is the correct answer.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality is -12≤2x-4<10.

Here, -12≤2x-4

Add 4 on both the sides of an inequality, we get

Answer:

Step-by-step explanation:

The graph of the geometric sequence 640, 160, 40, 10, ... should have the following characteristics:

Decreasing: The values in the sequence decrease at a constant rate, so the graph should decrease as well.

Straight Line: Since the sequence is a geometric sequence, the graph will be a straight line when plotted on logarithmic axes.

Negative Slope: The slope of the line should be negative, since the values are decreasing.

Non-Linear: When plotted on linear axes, the graph will not be a straight line and will curve downward, since the difference between consecutive terms is decreasing.

Therefore, the graph of the geometric sequence should appear as a straight line with a negative slope when plotted on logarithmic axes, and as a non-linear curve with a downward slope when plotted on linear axes.

When solving similar triangles, you must set up a proportion. We do not know what the other two lengths are for side AB, but we can still solve another way. For side AC, we can set up a proportion of 33/44. We're going to take AM and put that over the total. The total length of side AB is 24, and we're going to use x for AL.

33/44 = x/24

The correct equation to find the width, w, of the stone path would be: Option B. (2w+12) (2w+16) = 420

This is because the area of the garden and path is equal to the area of the rectangle with dimensions (12+2w) and (16+2w). Therefore, we can set up the equation:

(12+2w)(16+2w) = 420

Expanding and simplifying, we get:

4w² + 56w - 204 = 0

Dividing by 4, we get:

w² + 14w - 51 = 0

Factoring, we get:

Answer:

Step-by-step explanation:

The y-intercept of a linear equation in slope-intercept form, y = mx + b, represents the point at which the line crosses the y-axis. In this form, "m" represents the slope of the line and "b" represents the y-intercept.

If we have a graph of y = -9x + 11, the y-intercept can be found by setting x equal to 0 and solving for y:

y = -9x + 11

y = -9 * 0 + 11

y = 11

So, the y-intercept of the original graph is (0, 11).

Now, if we have a graph of y = -9x + 14, the y-intercept can be found in the same way:

y = -9x + 14

y = -9 * 0 + 14

y = 14

So, the y-intercept of the new graph is (0, 14).

Comparing the y-intercepts of the two graphs, we can see that the y-intercept of the new graph has shifted up by 3 units, from (0, 11) to (0, 14).

Therefore, the correct answer is A: The y-intercept of the new graph would shift up 3 units.
