Hey there!

Your answer is Option D.

Reason:

Product of 2and 9 = 2(9)

Product of 4 and 7 = 4(7)

Now; their sum = 2(9) + 4(7)

Therefore, your answer is Option D.

Answer:

Step-by-step explanation:

A relation is not a function if a vertical line intersects the graph MORE THAN ONCE.

A function is an expression, rule, or law in mathematics that describes a relationship between one variable (the independent variable) and another variable (the dependent variable).

If a vertical line meets the graph at exactly one point in all directions, the relation is a function. If a vertical line touches the graph more than once, the relationship is NOT a function.

Any vertical line in the plane can only intersect a function's graph once. As a result of the vertical line test, a curve in the plane represents the graph of a function if and only if no vertical line intersects it more than once.

Therefore, If a vertical line intersects the graph MORE THAN ONCE, the relation is not a function.

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer:

\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)

Step-by-step explanation:

Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.

\(A = \frac{h_{b}+b}{2}\)

Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.

By using trigonometric relations we will see that the area is:

How to find the area of one triangular section?

Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.

Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).

h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:

tan(60°) = x/h

x = tan(60°)*h

Then our two catheti are h and tan(60°)*h.

This means that the area will be:

Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Answer:

0.6 miles

Step-by-step explanation:

Jada:

3 miles ×3 hours= 9 miles

Elena:

2.8 miles × 3 hours = 8.4 miles

Equation:

9 - 8.4 = 0.6

Step-by-step explanation:

Since this scenario already uses mph (miles per hour), you can know that Jada had walked 3 miles in one hour and Elena had walked 2.8 miles in 1 hour. So, simply multiply both numbers by 3 to get how far they would have traveled in 3 hours.

3 * 3 = 9

2.8 * 3 = 8.4

So, after 3 hours, Jada has walked 9 miles and Elena has walked 8.4 miles. This means that if you subtract Elena's total distance from Jada's total distance, you will find how much farther Jada has walked

9 - 8.4 = 0.6 miles

Answer:

In 3 hours, Jada will have walked 0.6 miles farther than Elena.

Answer:

k = 2y^3 + z^3

Step-by-step explanation:

answer found by simplifying both sides of the equation, then isolating the variable.

To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).

The value of A/B is given as follows:

A/B = -2.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.

Answer:

second answer: y = 5x + 120; $180

Step-by-step explanation:

he starts with $120.

so, whatever else he does per month, there will always be the $120 starting amount to be added.

so, the third and the fourth answers are out.

then think : $5 every month.

that is how much after 2 months ? 2×5 = $10.

how much after 3 months ? 3×5 = $15.

so it has to be an equation that contains 5x (5 times the number of months).

combining both thoughts :

y = 5x + 120

now let's use x = 12 (for 12 months = 1 year).

5×12 + 120 = 60 + 120 = $180.

yes, it is that simple. no hidden "hocus pocus" is needed. just common sense.

Answer:

  1108 in²

Step-by-step explanation:

You want the total surface area of the pentagonal prism shown.

The area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...

  A = LW +1/2bh

  A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches

The lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.

  LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches

The total surface area of the figure is the sum of the two base areas and the lateral area:

  SA = 2(114 in²) +880 in² = 1108 in²

The surface area of the composite figure is 1108 in².
