Answer:

$2.15

Step-by-step explanation:

Since 3 Tomatoes cost $1.29

Then let's first find how much is 1 Tomatoes.

To do that we have to divide Cost by # of Tomatoes

3/1.29 = 0.43

Thus, 1 Tomatoes Cost 0.43

Now, the question is: How much will 5 tomatoes cost?

Therefore, 0.43 * 5 =2.15

Hence, 5 Tomatoes cost $2.15

Step-by-step explanation: Hi there.

For this answer I will show you the FOIL method.

Form: (ax-by)(cy-d)

1. Multiply ax and cy

2x*2y=4xy

2. Multiply ax and d

2x*8=16x

3. Multiply by and cy

-2y*2y=-4y^2

4. Multiply by and d

-2y*8=-16y

Add all of them together and you get:

-4y^2+4xy+16x-16y

Graph 1.

You have to look at the graph from left to right. If the starting point of the graph is higher than the endpoint, that means that the slope is negative. If the starting point is lower than the end point, it means the slope is positive.

Answer: Supplementary angles

Step-by-step explanation:

Bye have a nice day.

Answer:

does this help answer your question? Answer: They are supplementary angles, because angle 1 + angle 2 = 180° , i.e. they form a line.

Step-by-step explanation:

I would suggest that you memorize these -

    1. Complementary angles always =90°

For example, 30 degrees and 60 degrees are complementary angles.

    2. Adjacent angles are two angles that have a common side and a common vertex (corner point) but do not overlap in any way. (share a side)

    3. Supplementary angles are those that in sum give 180°.

    4. Vertical angels ---- each of the pairs of opposite angles made by two intersecting lines.

So, what have you learned? You learned that complementary angles are two angles that add up to 90 degrees, supplementary angles are two angles that add up to 180 degrees, vertical angles are opposite angles at an intersection of two straight lines, and adjacent angles are two angles that are next to each other.

Using the Central Limit Theorem, it is found that a larger sample size reduces the variability, that is, the experimental probabilities will be closer to the theoretical probabilities, which explains why the actual results are closer to the expected probability of 1/2 when rolling the cube 100 times.

It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard error [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].

That is, the standard error is inverse proportional to the square root of the sample size, hence a larger sample size reduces the variability, that is, the experimental probabilities will be closer to the theoretical probabilities, which explains why the actual results are closer to the expected probability of 1/2 when rolling the cube 100 times.

Answer: See below

Step-by-step explanation:

Rewrite in vertex form

f(x) = 2x^2-8x+1

f(x) = 2(x^2-4x) + 1

f(x) + ? = 2(x^2 -4x +?) + 1

To find ?, calculate (b/2)^2, in this case, b is 2

(2/2)^2

= 4

f(x) + 4 = 2(x^2 -4x +4) + 1

f(x) + 2*4 = 2(x^2 -4x +4) + 1

f(x) = 2(x-2)^2 -7

The sum of the length of the two sides of the triangle must be greater than the length of the third side. None of the triangles is formed. Then option A is correct.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

The sides of the triangle are 4.7 m, 1.6 m, and 2.9 m.

The condition will be

[tex]1.6 + 2.9 \ngtr 4.7[/tex]

We know that the sum of the length of two sides of the triangle must be greater than the length of the third side.

Hence, none of the triangles is formed.

Thus, option A is correct.

The negative leading coefficient tells you this parabola opens downward, so the vertex will be a maximum. The constant is the y-intercept, which is 58.

The vertex is nicely found using a graphing calculator, but can also be found algebraically. The x-value is ...

  x = -b/(2a) = -19.8/(2·(-4.9)) = 19.8/9.8 = 99/49 ≈ 2.02041

The value of f(99/49) is ...

  f(99/49) = (-4.9(99/49) +19.8)(99/49) +58 = (9.9)(99/49) +58 ≈ 78.002

The location of the vertex is approximately ...

  (x, y) ≈ (2.0204, 78.002) ≈ (2, 78)

It should be noted that a polygon is a flat two dimensional closed shape that has straight sides.

Your information is incomplete. Therefore, an overview of a polygon will be given.

A polygon simply means a plane figure which is described by a finite number of straight line segments that are connected in order to form a closed polygonal chain.

In this case, the length of a line segment can be measured by simply measuring the distance between the two endpoints.

It's simply the path between two points that has a definite length that can be measured.

Examples of polygon include triangles, quadrilateral, pentagon, etc.

The approximate difference in the ages of the two cars, which  depreciate to 60% of their respective original values, is 1.7 years.

Depreciation is to decrease in the value of a product in a period of time. This can be given as,

[tex]FV=P\left(1-\dfrac{r}{100}\right)^n[/tex]

Here, (P) is the price of the product, (r) is the rate of annual depreciation and (n) is the number of years.

Two different cars each depreciate to 60% of their respective original values. The first car depreciates at an annual rate of 10%.

Suppose the original price of the first car is x dollars. Thus, the depreciation price of the car is 0.6x. Let the number of year is [tex]n_1[/tex]. Thus, by the above formula for the first car,

[tex]0.6x=x\left(1-\dfrac{10}{100}\right)^{n_1}\\0.6=(1-0.1)^{n_1}\\0.6=(0.9)^{n_1}[/tex]

Take log both the sides as,

[tex]\log 0.6=\log (0.9)^{n_1}\\\log 0.6={n_1}\log (0.9)\\n_1=\dfrac{\log 0.6}{\log 0.9}\\n_1\approx4.85[/tex]

Now, the second car depreciates at an annual rate of 15%. Suppose the original price of the second car is y dollars.

Thus, the depreciation price of the car is 0.6y. Let the number of year is [tex]n_2[/tex]. Thus, by the above formula for the second car,

[tex]0.6y=y\left(1-\dfrac{15}{100}\right)^{n_2}\\0.6=(1-0.15)^{n_2}\\0.6=(0.85)^{n_2}[/tex]

Take log both the sides as,

[tex]\log 0.6=\log (0.85)^{n_2}\\\log 0.6={n_2}\log (0.85)\\n_2=\dfrac{\log 0.6}{\log 0.85}\\n_2\approx3.14[/tex]

The difference in the ages of the two cars is,

[tex]d=4.85-3.14\\d=1.71\rm years[/tex]

Thus, the approximate difference in the ages of the two cars, which  depreciate to 60% of their respective original values, is 1.7 years.
