0.48 cents per pound.

For this case we must find the unit cost of bananas, that is, one pound of banana. For this, we make a rule of three:

4lb -----------> $ 1.92

1lb -----------> x

Where the variable "x" represents the cost of a pound of banana.

[tex]x = \frac {1 * 1.92} {4}\\x = 0.48[/tex]

Thus, the banana pound costs $ 0.48.

If we round we have $ 0.50

Answer:

Step-by-step explanation:

f(x) + n - shift the graph n units up

f(x) - n - shift the graph n units down

f(x - n) - shift the graph n units to the right

f(x + n) - shift the graph n units to the left

------------------------------------------------------------------

We have f(x) = x² - 8

f(x) = x² - 8          add 5 to both sides

f(x) + 5 = x² - 3

Therefore your answer is D)

The graph of the function y=x^2-8 would shift 5 units up if changed to y=x^2-3, due to the increase in the constant term.

When comparing the functions y=x^2-8 and y=x^2-3, a change in the constant term represents a vertical shift of the graph. The constant term in the function y=x^2-8 is -8, and in the function y=x^2-3 it is -3. Since -3 is greater than -8 by 5, the graph will be shifted up by 5 units. Therefore, the correct answer to how the graph of the function would be affected is that it would shift 5 units up.

Step-by-step explanation:

The formula for the area of a circle is pi*r^2

We just plug in 8 for r and we get our answer.

Answer:

The correct answer is,

area of given circle = 200.96 feet square

Step-by-step explanation:

Formula:-

Area of circle = πr²

Where r is the radius of circle

To find the area of given circle

Here radius r = 8 feet

Area = πr² = 3.14 * 8² = 3.14 * 64

 = 200.96

Therefore area of given circle = 200.96 feet square

Answer:

The measure of the longer base is [tex]9\ cm[/tex]

The picture of the problem in the attached figure

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

[tex]A=\frac{1}{2}(b1+b2)h[/tex]

where

b1 ----> the measure of the shorter base

b2 ----> the measure of the longer base

h ---> is the height

In this problem we have

[tex]A=30\ cm^{2}[/tex]

[tex]b1=6\ cm[/tex]

[tex]h=4\ cm[/tex]

substitute the values and solve for b2

[tex]30=\frac{1}{2}(6+b2)4[/tex]

[tex]15=(6+b2)[/tex]

[tex]b2=15-6=9\ cm[/tex]

The measure of the longer base is:

                            9 centimeters

We know that the area of a trapezoid with height h and two parallel bases b and b' is given by the formula:

[tex]\text{Area of trapezoid}=\dfrac{1}{2}\times (b+b')\times h[/tex]

Here we have:

The area of a trapezoid is 30 square centimeters. The height is 4 centimeters. The shorter base measures 6 centimeters.

i.e.  

[tex]30=\dfrac{1}{2}\times (b+6)\times 4\\\\30=2(b+6)\\\\b+6=\dfrac{30}{2}\\\\b+6=15\\\\b=15-6\\\\b=9\ \text{centimeters}[/tex]

2. -52

3. 254.25

Answer:

1.the slope of the function f(x) is greater than the slope of the function g(x)

2. the y intercept in the function g(x) is the greater

Step-by-step explanation:

1. plot the graph for the function f(x)

identify points in on the line, i.e (2,6) and (1,0)

find the slope of function f(x)= change in y/change in x

m=(6-0)/2-1 = 6

equation for the function f(x)=   {y-6/x-2}=6

y-6=6x-12

y=6x-6

2. the equations for functions

f(x) is given by y=6x-6

g(x) is given by y=2x+6

y intercept for f(x) =- 6

y intercept for g(x)= +6

g(x) has greater y intercept.

QUESTION A

We can use any two points from the table to determine the slope of the linear function represented by table.

We use (0,-6) and (1,0).

We use the formula,

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

[tex]m = \frac{0 - - 6}{1 - 0} = 6[/tex]

For the second function

[tex]g(x) = 2x + 6[/tex]

This function is of the form;

[tex]y = mx + c[/tex]

where

[tex]m = 2[/tex]

is the slope.

The slope of f(x) is greater than the slope of g(x).

Part B

At y-intercept , x=0.

From the table, x=0 when y=-6.

Therefore f(x) has y-intercept -6.

For

[tex]g(x) = 2x + 6[/tex]

the y-intercept is 6.

Therefore g(x) has greater y-intercept.

The maximum height occurs at the vertex found using t = -b/2a

Solve for t

t = -20 / 2(-5) = -20/-10 = 2 seconds.

Now replace t with 2 in the original equation to solve for the height:

h(t) = -5t^2 + 20t + 110

h(2) = -5(2)^2 + 20(2) +110

h(2) = -5(4) + 40 + 110

h(2) = -20 + 40 + 110

h(2) = 130

Travis only threw the spike 130 meters. Since Laura is at 135 meters, the spike did not reach her.

1)Plane

2)Perpendicular Lines

3)Parallel lines

4)Circle

5)Angles

Final answer:

The five geometric terms—Plane, Perpendicular Lines, Parallel Lines, Circle, and Angle have been matched with their respective definitions using principles of Euclidean geometry.

Explanation:

Matching the geometric terms with their definitions will allow you to better understand the basic concepts of Euclidean geometry.

Plane: A flat surface that extends infinitely and has no depth; it has length and width.

Perpendicular Lines: Two lines that intersect at 90° angles.

Parallel Lines: Two lines that lie within the same plane and never intersect.

Circle: A set of all points in a plane that are a given distance from a point.

Angle: A figure consisting of two rays with a common endpoint.

Now you can match the terms to their definitions:

Plane - Definition 1

Perpendicular Lines - Definition 2

Parallel Lines - Definition 3

Circle - Definition 4

Angle - Definition 5

Answer:

Total area = (8.2)(8.2) + 4[1/2(8.2) (10.3)]

Step-by-step explanation:

From figure we can see a square pyramid with base edge 8.2 and slant height 10.3

Points to remember

Total area of square pyramid = Base area + Lateral face area

Lateral face area = 4 * One face area

To find the lateral face area

The face is like a triangle with base 8.2 and slant height = 10.3

Area of triangle = bh/2

Face area = 1/2(8.2) (10.3)

Lateral surface area = 4[1/2(8.2) (10.3)]

To find the base are

Base is a square with base edge = 8.2

Base area = side * side = (8.2)(8.2)

To find the total area of pyramid

Total area = Base area + Lateral face area

Total area = (8.2)(8.2) + 4[1/2(8.2) (10.3)]

Therefore the correct answer is first option

Answer:

(8.2)(8.2) + 4[1/2(8.2) (10.3)]

Ok, same way of solving then. Just with a few more useless numbers. Take rectangular prism A, 6in x 3in x 3in, you will get 54in^3.

Then take prism B, 2in x 3in x 7in, you will get 42in^3.

Finally, take those two numbers, add them, and you end up with 96in^3

Answer:

540g flour

4tsp baking powder

8tbsps sugar

520mL milk

4 eggs

8tbsps oil

Step-by-step explanation:

To find out how many times he would need to make the recipe, we can divide   20 by 5:

[tex]\frac{20}{5} =4[/tex]

Now we know that Sanjay must make the recipe four times to make 20 pancakes. We need to multiply each value by 4 to get how much he needs to make 20.

[tex](4)(135)=540\\(4)(1)=4\\(4)(2)=8\\(4)(130)=520\\(4)(1)=4\\(4)(2)=8[/tex]

Sanjay can make 20 pancakes by multiplying each ingredient in the original recipe for 5 pancakes by 4. This gives 540 g flour, 4 tsp baking powder, 8 tbsps sugar, 520 ml milk, 4 eggs, and 8 tbsps oil.

To adjust the quantities of ingredients for a recipe to make a different number of servings, we multiply the amounts of each ingredient by the factor that represents how many times the original number of servings we want to make. Sanjay's goal is to make 20 pancakes instead of 5, which is 4 times the original recipe. We'll multiply each ingredient quantity by 4 to find out how much of each is needed for 20 pancakes.

Multiply the amount of flour (135 g) by 4 to get 540 g of flour.

Multiply the amount of baking powder (1 tsp) by 4 to get 4 tsp of baking powder.

Multiply the amount of sugar (2 tbsps) by 4 to get 8 tbsps of sugar.

Multiply the amount of milk (130 ml) by 4 to get 520 ml of milk.

Multiply the amount of eggs (1 egg) by 4 to get 4 eggs.

Multiply the amount of oil (2 tbsps) by 4 to get 8 tbsps of oil.

Answer:

5x = 100°

4x = 80°

Step-by-step explanation:

We are given a diagram with a straight line AC being intersected by another line BD and we are to find the two mentioned angles.

We know that the two angles (5x° and 4x°) are supplementary so their sum would be equal to 180°.

So we can write it as:

[tex]5x+4x=180[/tex]

[tex]9x=180[/tex]

[tex]x=\frac{180}{90}[/tex]

[tex]x=20[/tex]

Finding the measure of both the angles:

[tex]5x = 5(20) =[/tex] 100°

[tex]4x = 4(20) =[/tex] 80°

Answer:

<ABD = 100° and <CBD = 80°

Step-by-step explanation:

From the given figure we can see a linear pair

To find the value of x

The given two linear pair angles are,

1). 5x°

2) 4x°

The sum of linear pair angles is 180°

Therefore we can write,

5x + 4x = 180

9x = 180

x = 190/9 = 20°

To find two angles

<ABD = 5x = 5 * 20 =  100° and

<CBD = 4x = 4 * 20 = 80°

Therefore two angles are, <ABD = 100° and <CBD = 80°

Answer:

x = (1/2)(ln 3)

Step-by-step explanation:

Please indicate exponentiation using the symbol " ^ ":

5e^(2x) - 4 = 11

To solve this, add 4 to both sides, obtaining:   5e^(2x) = 15

Next, divide both sides by 5, obtaining                e^(2x) = 3

Now take the natural logarithm (ln) of both sides:

2x = ln 3

Finally, divide both sides by 2, obtaining:           x = (1/2)(ln 3)

Answer:

17.3 in

Step-by-step explanation:

(a) Diagonal on a face

First, we calculate the diagonal f on a face of the cube.

a² + a² = f²

       f² = 2a²

(b) Diagonal of the cube

Consider the triangle made by the diagonal d, diagonal f, and the edge of the cube

                                                            d² =  f²   + a²

Substitute the value of f²                   d² = 2a² + a² = 3a²

Take the square root of each side     d = a√3

Substitute the value of a                     d = 10√3 = 10 × 1.732 = 17.3 in

The diagonal of the cube is 17.3 in.
