Answer:

Miranda has to put $13,661 in the bank.

Step-by-step explanation:

Miranda wants to give her 14-years old daughter $20,000 when she turns 18

Miranda has 4 years to make $20,000

Rate of interest = 10% per year

Let initial deposit be $x

Final amount (A) = $20,000

Time (t) = 4 years

Rate (r) = 0.10

Formula:

[tex]A=P(1+r)^n[/tex]

Substitute the values into formula

[tex]20000\geq x(1+0.1)^4[/tex]

Now we solve for x

[tex]x\geq \dfrac{20000}{1.1^4}=13660.27\approx 13661[/tex]

Hence, Miranda has to put $13,661 in the bank.

Well, you already know how to simplify these equations. There is nothing complicated about these, although it may look like they are. For problem 1, (2x^2)^3 is just multiplying the exponents. Add them together, and the numerator is 2x^5. The denominator is multiplying exponents again. 4x^4 * 3x^3 gives you 12x^7. The final answer is 2x^5 over 12x^7. Focus on the questions and keep your patience. You have the sheet that tells you all the rules for simplifying these equations. It shouldn't take too long. Just focus.

It's Answer A/The top answer. Vertical lines are x-values and horizontal lines are y-values, and since everything is shaded to the left of the purple line, it'd be x is less than or equal to 5

Answer:

[tex]x\leq5[/tex]

Step-by-step explanation:

In the graph we have vertical line at x=5

The vertical line is a solid line so we use <=  or >= symbol

For vertical line , the slope is undefined

so the equation becomes x= 5

For inequality we look at the shading region

the left side of the vertical line is shaded , so we use <= symbol

The final inequality is

[tex]x\leq5[/tex]

Answer:

6 per hour

Step-by-step explanation:you would divide 15 by 2 and 1/2

Part A:

The number of plants Nestor will pot in 1 hour is:

                     6 plants.

Part B:

The number of plants that he will be able to pot in 3 1/2 hour is:

                        21 plants.

Part A:

It is given that:

Nestor takes 2 1/2 hours to pot 15 plants.

i.e.

It takes him 5/2 hours to pot 15 plants.

Hence, In 1 hour he will pot:

[tex]\dfrac{15}{\dfrac{5}{2}}\ \text{plants}\\\\=\dfrac{15\times 2}{5}\ \text{plants}\\\\=6\ \text{plants}[/tex]

Part B:

Also, if he continues to work at the same rate then the number of plants he will pot in 3 1/2 hour is:

( We know that:

[tex]3\dfrac{1}{2}=\dfrac{3\times 2+1}{2}\\\\i.e.\\\\3\dfrac{1}{2}=\dfrac{7}{2}\ \text{hour}[/tex] )

Hence, the number of plants that will be potted in 7/2 hours is:

[tex]=6\times \dfrac{7}{2}\\\\=21\ \text{plants}[/tex]

So, we have:

Mean = (6 + 2 +5 + 3 + 4)/5

Evaluate

Mean = 4

Sort the data elements

2, 3, 4, 5, 6

The middle element is 4.

So, we have:

The vendor sold 77 hot dogs and 154 sodas at the hockey game. This was determined by setting up a system of equations from the given relationships and solving for each item.

At a hockey game, a vendor sold a combined total of 231 sodas and hot dogs, with the number of sodas being two times the number of hot dogs sold. To find the actual numbers, let's use the variables S for sodas and H for hot dogs. We can set up the following system of equations based on the given information:

By substituting the second equation into the first, we get:

This implies that the vendor sold 77 hot dogs. To find the number of sodas, we use the second equation:

Therefore, the vendor sold 154 sodas. We've solved the problem by using simple algebraic steps and applying the system of equations.

Let ABC be the triangle where A is at (0, a), B is at (0, 0) and C is at (a, 0).

Note that BA = BC = a, as ABC is isosceles.

Also, ∠B = 90°

After a dilation with a scale factor of 1.8 with the origin as the center of dilation, length BA will be increased to 1.8 times and will become B'A'.

So, point A will be moved to (0, 1.8a).

Similarly, point C will be moved to (1.8a, 0).

Now, slope of A'C' = [tex]\frac{0-1.8a}{1.8a-0}[/tex]

= - 1.

Hence, the dilation preserves the slope of the hypotenuse.

THE ANSWER IS Angle of rotation is changed if an image is moved about a central point.

Answer:

The images of PQR are P'=(8 , -6) , Q' = (8,6) and R' = (14 , -6)

Step-by-step explanation:

From the given graph:

the coordinates of PQR i.e,    

P= (4, -3) , Q= (4,3) , R= (7,-3)

Given: the scale factor of 2 and center of dilation at origin i.e (0,0)

The mapping rule for the  dilation applied to the triangle as shown below:

[tex](x, y) \rightarrow ( kx, ky)[/tex] where k represents the scale factor i.e, k=2 or we can write it as ;

[tex](x, y) \rightarrow (2x, 2y)[/tex]

For P = (4, -3)

The image P' = [tex](2\cdot 4 , 2\cdot (-3))[/tex]

⇒ P'= [tex](8, -6)[/tex]

Similarly for Q = (4, 3) and R = (7 , -3)

the image of Q' = [tex](2\cdot 4 , 2\cdot (3)) = (8 , 6)[/tex]

The image of R' = [tex](2\cdot 7 , 2\cdot (-3)) = (14 , -6)[/tex]

Now, plot the graph of PQR as shown in the attachment:

The images of the vertices of PQR are P' (8, -6), Q' (8, 6), and R' (14, -6).

A graph that shows triangle PQR and the image triangle P'Q'R is shown in the picture below.

In Mathematics and Geometry, a dilation is a type of transformation which typically changes the size (dimensions) of a geometric object, but not its shape.

In this scenario an exercise, we would dilate the coordinates of the pre-image (triangle PQR) by applying a scale factor of 2 that is centered at the origin (0, 0) in order to produce the coordinates of its image as follows:

Vertices P (4, -3) → (4 × 2, -3 × 2) = P' (8, -6).

Vertices Q (4, 3) → (4 × 2, 3 × 2) = Q' (8, 6).

Vertices R (7, -3) → (7 × 2, -3 × 2) = R' (14, -6).

In concluson, we can logically deduce that the dilation is an enlargement because the size of the pre-image is smaller than the image.

Answer:

D. The total amount of sales

Step-by-step explanation:

We have been given that a jewelry sales person earns a base salary of $200 a week plus 25% of all of her sales over $300.

This situation has been represented using the expression 200 + .25( x - 300)

Here 200 is the base salary. 0.25 corresponds to 25%. The factor (x-300) corresponds to the amount of sales over 300 dollars. This implies that x represents the total sales.

Therefore, x represents the total amount of sales. Hence, option (D) is the correct answer.

The answer is B.

The area of a rectangle with a length of 12x and a width of (x + 3) is 12x² + 36x, which is option D in the provided list of answers.

To find the area of a rectangle, you multiply the length by the width. In this case, the length is given as 12x and the width is (x + 3). Multiplying these two expressions together, you get:

Area = Length × Width

Area = 12x × (x + 3)

Now, distribute the 12x across the terms inside the parentheses:

Area = 12x × x + 12x × 3

Area = 12x² + 36x

Therefore, the area of the rectangle is 12x² + 36x, which corresponds to option D in your list of possible answers.

The correct option is D.

The area of the rectangle is 12x² + 36x.

To find the area of a rectangle, multiply its length by its width. In this case, the length is given as 12x and the width is given as (x + 3).

So, Area = Length × Width = (12x) × (x + 3).

Expanding this expression, we get:

Area = 12x² + 36x.

Therefore, the area of the rectangle is 12x² + 36x.

So, the correct answer is option D) 12x² + 36x.

Here's why:

1. Substitute the given values for length and width into the formula for the area of a rectangle.

2. Multiply the length by the width, distributing the 12x over the (x + 3).

3. Combine like terms to simplify the expression.

4. The final expression for the area is 12x² + 36x.

The coordinates of the fourth vertex of the rectangular blanket, given the vertices (-2.6, -3.4), (-2.6, 1.3), and (1.6, 1.3), are (1.6, -3.4).

From the given coordinates of the three vertices of the rectangle, we can find that the width of the rectangle is calculated from the difference in the x-coordinates of (-2.6, 1.3) and (1.6, 1.3), which is 4.2 units (1.6 - (-2.6)). Similarly, the length of the rectangle is calculated from the difference in the y-coordinates of (-2.6, -3.4) and (-2.6, 1.3), which is 4.7 units (1.3 - (-3.4)).

To find the fourth vertex, we take the x-coordinate of the bottom left vertex (-2.6, -3.4) and add the width (4.2) to get 1.6. We then take the y-coordinate of the bottom left vertex (-2.6, -3.4) and keep it the same for the fourth vertex. So the coordinates of the fourth vertex are (1.6, -3.4).
