Answer:

The coordinates of E are [tex]E(x,y) = \left(\frac{9}{2}, 0 \right)[/tex].

Step-by-step explanation:

The triangle ABC represents a right triangle as both sides AB and AC are orthogonal to each other. The side AB is in the y axis, whereas the side AC is in the x axis. The triangle is dilated with respect to the origin, in which point A is set.

Vectorially speaking, dilation is defined by the following operation:

[tex]P'(x,y) = O(x,y) + k\cdot [P(x,y) - O(x,y)][/tex] (1)

Where:

[tex]O(x,y)[/tex] - Point of reference.

[tex]P(x,y)[/tex] - Original point.

[tex]P'(x,y)[/tex] - Dilated point.

[tex]k[/tex] - Dilation factor.

By applying this operation, point B becomes point D:

[tex]B(x,y) = (0,4)[/tex], [tex]D(x,y) = (0,6)[/tex]

[tex]D(x,y) = (0,0) + k\cdot [(0,4)- (0,0)][/tex]

[tex]D(x,y) = (0,0) + k\cdot (0,4)[/tex]

[tex](0,6) = (0,0) +(0,4\cdot k)[/tex]

[tex](0, 6) = (0,4\cdot k)[/tex]

[tex]k = \frac{3}{2}[/tex]

Lastly, we transform point C into point E by applying the same operation: [tex]C(x,y) = (3, 0)[/tex], [tex]O(x,y) = (0,0)[/tex] and [tex]k = \frac{3}{2}[/tex]

[tex]E(x,y) = (0,0) + \frac{3}{2}\cdot [(3,0)-(0,0)][/tex]

[tex]E(x,y) = \left(\frac{9}{2}, 0 \right)[/tex]

The coordinates of E are [tex]E(x,y) = \left(\frac{9}{2}, 0 \right)[/tex].

Answer:

30.48 centimeters

Step-by-step explanation:

We know that:

2.54 cm = 1 inch

To find how many centimeters are in 12 inches, you should:

2.54 x 12 = 30.48

So Jacob’s pieces of yarn should be 30.48 centimeters long.

Hope this helps!

Jacob's pieces of yarn should be 30.48 centimeters long.

To find out how many centimeters long Jacob's pieces of yarn should be, we can use the conversion factor that there are 2.54 centimeters in an inch.

Since Jacob needs pieces of yarn that are 12 inches long, we can calculate the length in centimeters using the conversion:

Length in centimeters = Length in inches * Conversion factor

Length in centimeters = 12 inches * 2.54 centimeters/inch

Length in centimeters = 30.48 centimeters

So, Jacob's pieces of yarn should be 30.48 centimeters long.

The rug and the steps are missing,so i have attached it.

Answer:

27 ft²

Step-by-step explanation:

From the rug attached, we can see that the steps are indicated in blue footprints.

Now, the horizontal foot prints will intersect the vertical one after 4.5 footprints.

While the vertical one will intersect the horizontal one after approximately 3 footprints.

Each foot is 12 inches.

Now, 1 ft = 12 inches.

Thus;

Vertical = 4.5 ft and horizontal = 3 ft

Thus;

Area of that portion = 4.5 × 3 = 13.5 ft²

Now, that is only half way.

Thus, for full part = 13.5 × 2 = 27 ft²

Answer:

This is an isosceles triangle, meaning it has 2 congruent angles and one other angle.

Looking at this triangle, we know that ∠B = ∠C.

∠B = 57 degrees

All the angles in a triangle add up to 180, so you need to subtract the two values from 180 to get ∠A.

∠A = 180 - 57 - 57

       = 66 degrees

Step-by-step explanation:

Hi there!

SSS similarity theorem is a theorem that can determine similar triangles; the criteria for SSS~ is that the corresponding sides of the triangles create proportions which is the same as the ratio of similitude (k)

First, we need to find the ratio of similitude.

We need to assume that the triangles are similar.

15 corresponds with 20 (if you turn both triangles until they're titled the same way, you will see that 15 and 20 are the measures of the same sides on the triangles)

so that means 15/20 must make the ratio of similitude

15/20 is equal to 3/4

therefore k=3/4

as the triangle is already assumed similar, that means that 21/x will also give us a ratio that is equal to 3/4 (ratio of similitude)

therefore, 21/x=k

Since both ratios are equal to k, set 3/4 and 21/x equal to each other. This is possible via a property called transitivity (if a=b and b=c, then a=c)

3/4=21/x

cross multiply

3x=84

divide both sides by 3

x=28

So that means that 28 will make the triangles similar by SSS similarity

*you double check by doing 21/28 and see that it's also equal to 3/4

5^-2 * 5x = 1

Simplify:

5^-2 = 1/25

Now you have 1/25 * 5x = 1

1/25 x 5 = 1/5

1/5x = 1

Divide both sides by 1/5 ( when dividing by a fraction, flip the fraction over an multiply)

x - 1 x 5/1 = 5

X = 5

Answer:

The function notation for the given equation and then solve the function for the value [tex]x=\dfrac{1}{3}[/tex].

Solution:

We have,

[tex]y=-\dfrac{2}{5}x+\dfrac{3}{8}[/tex]

Substitute [tex]y=f(x)[/tex] in the given equation to find the function notation of it.

[tex]f(x)=-\dfrac{2}{5}x+\dfrac{3}{8}[/tex]

Substituting [tex]x=\dfrac{1}{3}[/tex], we get

[tex]f(\dfrac{1}{3})=-\dfrac{2}{5}(\dfrac{1}{3})+\dfrac{3}{8}[/tex]

[tex]f(\dfrac{1}{3})=-\dfrac{2}{15}+\dfrac{3}{8}[/tex]

[tex]f(\dfrac{1}{3})=\dfrac{-16+45}{120}[/tex]

[tex]f(\dfrac{1}{3})=\dfrac{29}{120}[/tex]

Therefore, the function notation is [tex]f(x)=-\dfrac{2}{5}x+\dfrac{3}{8}[/tex] and the value of the function at [tex]x=\dfrac{1}{3}[/tex] is [tex]\dfrac{29}{120}[/tex].

The  account will have $1536.007 after 9 years.

Part A:

To express the total amount of money A(t) in the account after 7 years, we can use the formula:

A(t) = P[tex](2^t)[/tex]

where:

A(t) is the total amount in the account after t years,

P is the initial amount in the account (starting with $3.00 in this case),

t is the number of years.

Substituting the values into the formula, we get:

A(t) = 3 ([tex]2^7[/tex])

A(t) = 3 x 128

A(t) = 384

Therefore, the total amount of money in the account after 7 years is $384.

B) To find out after how many years the account will have $1536.007, we need to solve the equation:

1536.007 = 3 [tex](2^t)[/tex]

Dividing both sides of the equation by 3, we get:

512.0023333333 = [tex]2^t[/tex]

Taking the logarithm (base 2) of both sides, we have:

log2(512.0023333333) = t

t = 9.000317.

Therefore, the account will have $1536.007 after 9 years.
