The true statements are:

(B) Both figures are congurent.

(C) The two figures have the same orientation but different positions.

(E) Corresponding angles and sides have the same measures.

In geometry, how an item is positioned in the space it occupies—such as a line, plane, or rigid body—is described in terms of its orientation, angular position, attitude, bearing, and direction.

It refers more particularly to the fictitious rotation required to shift an object from a reference placement to its present location.

To get to the current positioning, a rotation might not be sufficient.

It could be required to include a fictitious translation known as the object's location (or position, or linear position).

Together, the position and orientation completely explain where the object is situated in space.

Therefore, the true statements are:

(B) Both figures are congurent.

(C) The two figures have the same orientation but different positions.

(E) Corresponding angles and sides have the same measures.

Answer: 45

Step-by-step explanation:

The length of the fence must be 618cm

The volume that it can hold is 1,909,620 cm³

First, the fence is just equal to the circumference of the cylinder, remember that the circumfernce of a circle of diameter D is:

C = П*D

Here we use П = 3, then:

C = П*206cm

C = 3*206cm = 618cm

Now the volume, for a cylinder of diameter D and height H, the volume is:

V = П*(D/2)²*H

Replacing the values that we know we will get:

V = 3*(206cm/2)²*60cm = 1,909,620 cm³

Based on the information in the image, we can infer that the recipe that takes the longest is the one for spaghetti sauce.

To find the recipe that takes the longest we must take into account the information of each of the recipes. In this case, we have preparation time and cooking time. To know the total time we must add these two values.

Additionally, we must establish a magnitude to be able to relate all the values, in this case the most appropriate would be the number of minutes.

So, the preparation of the spaghetti sauce takes 10 minutes and its cooking takes an hour and a half, that is, 90 minutes. On the other hand, strawberry bread takes 20 minutes to prepare and 55 to cook:

According to the above, the spaghetti sauce takes longer because it takes 25 minutes longer than the strawberry bread.

The first term of the geometric sequence is 1/2 and the common ratio is 2.

What is the geometric sequence?

A geometric sequence is a sequence of numbers in which each term after the first is obtained by multiplying the previous term by a fixed number called the common ratio. The general form of a geometric sequence is:

a, ar, ar², ar³, ar⁴, ...

where 'a' is the first term, 'r' is the common ratio, and the subscripts represent the position of the term in the sequence.

Let's denote the first term of the geometric sequence by "a" and the common ratio by "r".

We know that the third term of the sequence is 2, which means that:

a * r² = 2 (1)

We also know that the sixth term of the sequence is 16, which means that:

a * r⁵ = 16 (2)

Now we can solve for "a" and "r" by dividing equation (2) by equation (1):

(a * r⁵)/(a * r²) = 16/2

Simplifying, we get:

r³ = 8

Taking the cube root of both sides, we get:

r = 2

Now we can use equation (1) to solve for "a":

a * 2² = 2

Simplifying, we get:

4a = 2

a = 1/2

Therefore, the first term of the geometric sequence is 1/2 and the common ratio is 2.

Answer:

y = -3x + 7

Step-by-step explanation:

To start with the slope, given by two points on the graph:

(0, 7) and (1, 4):  

Let x1 = 0

x2 = 1

y1 = 7

y2 = 4

We can use the following slope formula:

\(m = \frac{(y_{2} - y_{1})}{(x_{2} - x_{1})} = \frac{rise}{run}\)

\(m = \frac{(4-7)}{(1-0)} = \frac{-3}{1} = -3\)

It is a negative slope because it is sloping downwards.

Now that we have our slope, we can move on to the y-intercept, ( b ). The y-intercept is the value of y when the value of x = 0.  Looking at the graph, we can see that the y-intercept is (0, 7). It is usually the point where it touches the y-axis.

Now that we have our slope (m ) and y-intercept ( b ), we can establish our linear equation in the slope-intercept form, y = mx + b:

y = -3x + 7

The slope of the line that passes through the given points is equal to 8/7.

Given the following data:

Points on x-axis = (-2, -10).

Points on y-axis = (-2, -9).

A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.

Mathematically, the slope of any straight line can be calculated by using this formula;

\(Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\)

Substituting the given points into the formula, we have;

Slope = (-10 - (-2))/-9 - (-2))

Slope = (-10 + 2)/(-9 + 2)

Slope = -8/-7

Slope = 8/7

In conclusion, the slope of the line that passes through the given points is equal to 8/7.

To solve the savings plan balance, we have to calculate the interest for 19 months. The formula for calculating interest for compound interest is given below:$$A = P \left(1 + \frac{r}{n} \right)^{nt}$$where A is the amount, P is the principal, r is the rate of interest, t is the time period and n is the number of times interest compounded in a year.

The given interest rate is 11% per annum, which will be converted into monthly rate and then used in the above formula. Therefore, the monthly rate is $r = \frac{11\%}{12} = 0.0091667$.

The monthly payment is $PMT = $250. We need to find out the amount after 19 months. Therefore, we will use the formula of annuity.

$$A = PMT \frac{(1+r)^t - 1}{r}$$where t is the number of months of the plan and PMT is the monthly payment. Putting all the values in the above equation, we get:

$$A = 250 \times \frac{(1 + 0.0091667)^{19} - 1}{0.0091667}$$$$\Rightarrow

A = 250 \times \frac{1.0091667^{19} - 1}{0.0091667}$$$$\Rightarrow

A =250 \times 14.398$$$$\Rightarrow A = 3599.99$$

Therefore, the savings plan balance after 19 months with an APR of 11% and monthly payments of $250 is $3599.99 (approx).

Answer:

A = 120

Step-by-step explanation:

To find angle A we will need to use the law of cosines, since we know the three sides of the triangle.

a^2=b^2+c^2−2*b*c*cosA

(2 sqrt(13)) ^2 = 6^2 + 2^2  + 2 * 6 * 2 cos A

4*13 = 36 + 4 - 24 cos A

52 = 40- 24 cos A

12 = -24 cos A

-1/2 = cos A

Take the inverse cos of each side

cos^-1(-1/2) = cos^-1(cos A)

120 = Cos A  or 240 = Cos A

A cannot be greater than 180 so A = 120

Answer:

A = 120°

Step-by-step explanation:

We can use the cosine rule to solve for angle A, since lengths of all sides are known:

\(a^2 = b^2+ c^2 - 2(b)(c) \space\ cos A\)

where a, b, and c are the sides opposites angles A, B, and C respectively.

∴ a = 2√3 , b = 6, c = 2

• Rearranging the formula to make A the subject:

\(2(b)(c) \space\ cos A = b^2 + c^2 -a^2\)

⇒  \(cos A = \frac{b^2 + c^2 -a^2}{2(b)(c)}\)

⇒  \(A = cos^{-1}(\frac{b^2 + c^2 -a^2}{2(b)(c)} )\)

• Now we can substitute the values into the equation to calculate the value of angle A:

\(A = cos^{-1}(\frac{6^2 + 2^2 -(2\sqrt{13})^2}{2(6)(2)} )\)

⇒  \(A = cos^{-1} (-\frac{1}{2} )\)

⇒  A = 120°

The two cars must be approximately 177.34 feet apart from each other for Spiderman to have different depression angles to each car.

To find the distance between the two cars, we can use trigonometry and the concept of similar triangles. Let's denote the distance between Spiderman and the nearest car as d1 and the distance between Spiderman and the farther car as d2.

In a right triangle formed by Spiderman, the height of the hotel, and the line of sight to the nearest car, the tangent of the depression angle (52 degrees) can be used:

tan(52) = 600 / d1

Rearranging the equation to solve for d1:

d1 = 600 / tan(52)

Similarly, in the right triangle formed by Spiderman, the height of the hotel, and the line of sight to the farther car, the tangent of the depression angle (46 degrees) can be used:

tan(46) = 600 / d2

Rearranging the equation to solve for d2:

d2 = 600 / tan(46)

Using a calculator, we can compute:

d1 ≈ 504.61 feet

d2 ≈ 681.95 feet

The distance between the two cars is the difference between d2 and d1:

Distance = d2 - d1

Plugging in the values, we have:

Distance ≈ 681.95 - 504.61

Distance ≈ 177.34 feet
