Answer 1

Answer:

b = 40 , c = 70

Step-by-step explanation:

given a quadratic function in standard form

y = ax² + bx + c ( a ≠ 0 )

then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = 5x² + bx + c ← is in standard form

with a = 5 and b = b , then

x = - [tex]\frac{b}{10}[/tex]

equating to the given x- coordinate of the vertex , that is - 4

- [tex]\frac{b}{10}[/tex] = - 4 ( multiply both sides by - 10 )

b = 40

then

y = 5x² + 40x + c

substitute (- 4, - 10 ) into the equation and solve for c

- 10 = 5(- 4)² + 40(- 4) + c

- 10 = 5(16) - 160 + c

- 10 = 80 - 160 + c

- 10 = - 80+ c ( add 80 to both sides )

70 = c

then b = 40 and c = 70

What is a proportional relationship?


A proportional relationship is one in which one variable in the relationship is a constant multiple of the other variable.

The table of values can be presented as follows;

x; 15 9 21

y; 5  3  7

The domain of the function is therefore;  15, 9, 21

The range of the function is therefore; 5, 3, 7

The coordinates of points on the graph of the  function is therefore;

(15, 5), (9, 3), (21, 7)

The relationship between the xi and y-values of the function is therefore;

5/15 = 3/9 = 7/21 = 1/3

The constant of proportionality in the relationship is 1/3

The relationship is therefore a proportional relationship.

The characteristics of the graph of a proportional relationship includes;

The graph passes through the origin, (0, 0).

The correct option that therefore describes the graph is the option;

Answers

The equation of line is y + 2x +7 =0 for the points (-5,3) and (0,-7).

What is equation of line?

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.

The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

The given points are (-5, 3) and (0, -7).

To find the equation of line, use formula,

y - y₁ = m(x - x₁) where m = (y₂-y₁)/(x₂-x₁),

y - 3 = (-7 - 3)/(0-(-5)) (x - (-5))

y - 3 = -10 / 5 (x + 5)

y - 3 = -2 (x + 5)

y + 2x +7 =0

Think About the Process You have 30 quarters. You find 20% more quarters in your room. Then you go shopping and spend ​50% of the total number of quarters. Write an expression to represent the total number of quarters you take with you shopping.​ Calculate, in​ dollars, the amount of money you have left.

Answers

Answer: $4.5 left.

Step-by-step explanation:

You have 30 quarters, and find 20% more. To convert percentages to decimals for calculations, simply move the decimal two spaces to the left.

20% is 20. ---> 2.0 ---> .20

30 * 0.2 = 6.    Now add 6 (found) to 30 (original) to get the total.

30+6 = 36 total quarters.

You spend 50% of the quarters, 36 * 0.5 = 18.

This means you have 18 quarters left (or you spent 18).

18 quarters, each quarter is worth 0.25 dollars, so multiply the number left by how much each is worth.

18 * 0.25 = $4.5.

$4.50 is the amount left

a. How many cubes with an edge length of b. What is the volume, in cubic inches, of inch are needed to build a cube with one cube with an edge length of inch? an edge length of 1 inch?

Answers

The number of cubes of edge length 1/3 is 27 and the volume of the cube is 1 cubic inches

How to determine the number of cubes

From the question, we have the following parameters that can be used in our computation:

Edge length of cube 1 = 1/3 inchEdge length of cube 2 = 1 inch

The volume of a cube is the cube of its edge length

This means that the volumes are

Volume = Edge length³

So, we have

Volume of cube 1 = (1/3 inch)³ = 1/27 cubic inches

Volume of cube 2 = (1 inch)³ = 1 cubic inch

The number of cubes is then calculated as

Number of cubes = Volume of cube 2/Volume of cube 1

This gives

Number of cubes = 1/(1/27)

Number of cubes = 27

The volume of the cubes

Here, we have

Edge length of cube = 1 inch

The volume of a cube is the cube of its edge length

This means that the volumes are

Volume = Edge length³

So, we have

Volume of cube = (1 inch)³ = 1 cubic inch

In Silvergrove, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 9 kilometers and the distance between the courthouse and the city pool is 10 kilometers, how far is the library from the community pool? If necessary, round to the nearest tenth.

Answers

The distance of the library from the community pool is given  as 4.4 km

How to solve for the distance

We have to solve this problem with the use of the Pythagoras theorem.

The formula is given as

a² = b² + c²

The total distance flown would be represented by a = 10 kilometer

the distance for the courthouse would be given as 9 kilometers

When we put these values in the formula we would have

10² = a² + 9²

100 = a² + 81

a² = 100 - 81

a² = 19

a = √19

a = 4.4 km

Hence the calculated distance is given a 4.4 km from the library to pool.

Which category has the highest joint frequency?

Frosting No frosting Total

sugar cookies 56 120 176

Chocolate cookie 66 70 136

Red velvet 38 50 88

Total 160 240 400

Chocolate cookies with frosting = Total chocolate cookies - chocolate cookies with no frosting

= 136 - 70

= 66

Red velvet cookies with frosting = Total cookies with frosting - (Chocolate cookies with frosting + sugar cookies with frosting)

= 160 - (56 + 66)

= 160 - 122

= 38

Total red velvet cookies = Red velvet cookies with frosting + Red velvet cookies with no frosting

= 50 + 38

= 88

Total cookies with no frosting = Total cookies - Total cookies with frosting

= 400 - 160

= 240

Total sugar cookies with no frosting = Total cookies with no frosting - (chocolate cookies with no frosting + Red velvet cookies with no frosting)

= 240 - (70 + 50)

= 240 - 120

What is simple interest?

Simple interest is defined as the amount of interest paid on a specific principal, an amount at a specific interest rate. It is given by

I = Prt

where, I = simple interest, P = Principal, r = rate of interest, t = time taken

Given, P = $100

I = $135

r = 0.15

t = ?

So, simple interest is given by:

I = Prt

or, 135 = 100*0.15*t

or, 135 = 15*t

or, t = (135/15) = 9 years = 9*12 = 108 months

The width of a rectangle is 4 more than the length. If the perimeter is 36 cm, ind the dimensions (length and width) of the rectangle.

Answers

Answer with step-by-step explanation:

Let the width of the rectangle be x.

Given that,

length ⇒ 4

width ⇒ x + 4 ( Because, the rectangle's width is 4 more than the length.)

Perimeter ⇒ 36cm

The formula to find the perimeter of rectangle is:

P = 2 ( l + w )

Now to find the value of x replace P, l & w with 36, 4 & (x + 4) with respectively.

P = 2 ( l + w )

36 = 2 ( 4 + x + 4 )

36 = 2 ( x + 8 )

Solve the brackets.

36 = 2x + 16

Substract 16 from both sides.

36 - 16 = 2x

20 = 2x

Divide both sides by 2.

10 = x

And now let us find the exact dimensions of the rectangle.

Length = 4 cm

Width = x + 4 = 10 + 4 = 14 cm

The half-life of a drug in the bloodstream is 14 hours. What fraction of the original drug dose remains in 36 hours? in 72 hours?

Answers

16.82 % and 2.83% of the original drug dose remain in 36 hours and 72 hours respectively.

What is half-life?

Half-life is a characteristic unit for the exponential decay equation and is constant across the lifespan of an exponentially decaying quantity.

Given, the half-life of a drug(h) = 14 hours

The first condition, time duration (t) = 36 hours

Then, the half-life of the substance can be calculated by:

    [tex]A = A_{0} * (1/2)^{\frac{t}{h} }[/tex]

or, [tex]A = A_{0} * (1/2)^{\frac{36}{14} }\\A = A_{0} * (0.1682)\\[/tex]

16.82 % of the original drug dose remains in 36 hours

Hence, 16.82 % of the original drug dose remains in 36 hours

The second condition, time duration (t) = 72 hours

Then, the half-life of the substance can be calculated by:

 [tex]A = A_{0} * (1/2)^{\frac{t}{h} }[/tex]

[tex]A = A_{0} * (1/2)^{\frac{72}{14} }\\A = A_{0} * (0.0283)\\[/tex]

2.83 % of the original drug dose remains in 72 hours

Hence, 2.83 % of the original drug dose remains in 72 hours
