Kaitlyn has a least five purses (how to i solve that with signs and number?)

Answer:

Roman numeral representing thousand (1000)

Answer:

18 in. x 10 in.

Step-by-step explanation:

Squares will always have equal lengths. So, you need to figure out what will multiple by itself to get 196, and it’s 14.

Since you know in the equation that if 4 were to be taken away from the length and added to the width, it would make the 14 x 14 square, you can subtract 4 from one of the 14’s and add 4 to the other 14.

So, then you get (14-4) 10 in. x (14+4) 18 in.

h(n) = -17·0.2^(n-1)

The amount of the first application that has been downloaded is 6.48 megabytes

The size of the second application is 7.35 megabytes

The first application has a size of 10.8 megabytes and out of this 10.8 megabytes, only 60% has completely downloaded. The amount that has already downloaded is therefore:

= Size of application x Percentage downloaded

= 10. 8 x 60%

= 6.48 megabytes

The second application is sized such that it is 3.45 MB less than the first application. The size of the application is therefore:

volume = π * 1.25² * 15

volume = π * 1.5625 * 15

volume =  π * 23.4

$225 was earned from the craft sales

and $40 was earned from the play.

Given, During a school carnival, students from the middle school raised money by selling crafts, food, game tickets, and school play admissions.

Of each dollar earned, $0.15 came from games. Craft sales earned 3 times as much as games. Food sales were 4 times the amount earned from the play.

Let the amount earned by play be x,

Now, Games earned = 0.15×500 = $75

Also, crafts earned 3×75 = $225

Now, as play earned x, then food earned 4x.

According to question,

x + 75 + 225 + 4x = 500

5x + 300 = 500

5x = 200

The area of the given trapezium is 16x + 8

Area of trapezium:

The general formula to calculate the area (A) of a trapezium is written as,

A = ½ (a + b) h where,

where

a, b = bases of trapezium, and,

h = height

Given,

Here we have the figure of trapezium and the measures are written in it.

Now, we have to find the area of the trapezium.

According to the formula of the area of the trapezium,

We need the value of base and height.

By looking into the given figure, we have identified the value of

a = x cm

b = 3x + 2 cm

h = 8 cm.

Then the area of the trapezium is calculated as,

A = ½ (x + (3x +2)) 8

A = ½ (4x + 2) 8

A = 4 (4x + 2)

A = 16x + 8

Answer:

P = 84

Step-by-step explanation:

Area = length* width or A = lw

We know that the length is 5 times its width which can also mean

[tex]l = 5*w[/tex] or [tex]l=5w[/tex]

Use the formula for area and replace [tex]l[/tex] with [tex]5w[/tex] and the total area with 245

[tex]A = lw\\245=5w(w)[/tex]

Multiply:

[tex]245=5w^{2}[/tex]

Divide by 5

[tex]49=w^2[/tex]

Square root of [tex]w^2[/tex]

[tex]\sqrt{49}=\sqrt{w^2}[/tex]

Simplify

[tex]7=w[/tex]

Now that we know w = 7 we can input this into the Perimeter formula

(P = 2l +2w)

P = 2(5*7)+2(7)   // Note: Remember [tex]l[/tex] = 5*w and w = 7

P = 84

Answer:

There are two pairs of numbers:

-8      -18

and

18        8

Step-by-step explanation:

a * b = 144      EQ. 1

a - b = 10         EQ. 2

From EQ. 2:

a = 10 + b          EQ. 3

Replacing EQ. 3 in EQ. 1:

(10+b)b = 144

10*b + b*b = 144

b² + 10b - 144 = 0

b = {-10±√((10²)-(4*1*-144))} / (2*1)

b = {-10±√(100+576)} / 2

b = {-10±√676} / 2

b = {-10±26} / 2

b₁ = {-10-26} / 2 = -36/2 = -18

b₂ = {-10+26} / 2 = 16/2 = 8

a₁ - b₁ = 10

a₁ - (-18) = 10

a₁ + 18 = 10

a₁ = 10 - 18

a₁ = -8

a₂ - b₂ = 10

a₂ - 8 = 10

a₂ = 10 + 8

a₂ = 18

Check:

a₁ * b₁ = -8 * -18 = 144

a₂ * b₂ = 8 * 18 = 144

The equation of line in slope intercept form is y=−9/8x+7.

In the given question we have to write the equation of the graph line in slope intercept form.

The give points are(0,7) and (8,−2)

Let x(1)=0, y(1)=7, x(2)=8 and y(2)=−2.

The slope intercept form of equation is

y−y(1)=m(x−x(1))+c.........(1)

Before finding the equation we find the slope of equation.

Slope(m)={y(2)−y(1)}/{x(2)−x(1)}

Now putting the value

m=(−2−7)/(8−0)

m= −9/8

Now putting the value in equation 1

y−7=−9/8(x−0)

Now the equation is

y−7=−9/8x

Add 7 on both side

y−7+7=−9/8x+7

y=−9/8x+7

Hence, the equation of line in slope intercept form is y=−9/8x+7.

The graph of the polar curve r = 3 – 2cos(θ) is in the attachment

A graph is a diagram representation on a coordinate system.

A polar curve is a curve represented by the equation r = a + bcosθ where

To find the graph of the polar curve r = 3 – 2cos(θ), we need to determine its maximum and minimum values and also the value as it crosses the axis.

Since r = 3 – 2cos(θ), the maximum value of r is obtained at the minimum value of cos(θ) = -1 at θ = π

So, substituting this into the equation, we have

r = 3 – 2cos(θ)

r = 3 – 2(-1)

r = 3 + 2

r = 5

Since r = 3 – 2cos(θ), the minimum value of r is obtained at the maximum value of cos(θ) = 1 at θ = 0

So, substituting this into the equation, we have

r = 3 – 2cos(θ)

r = 3 – 2(1)

r = 3 - 2

r = 1

Since r = 3 – 2cos(θ), the value of r at the origin is when θ = π/2 and θ = 3π/2

So, substituting this into the equation, we have

r = 3 – 2cos(θ)

r = 3 – 2cos(π/2)

r = 3 – 2(0)

r = 3 - 0

r = 3

Round 8.879 to the nearest tenth is 8.9.

Rounding to the nearest tenth:

The combination of a whole number and a fraction, separated by a decimal point, is known as a decimal number in mathematics. The place value of the digits is divided by 10 starting from left to right. Determining the place values of tenths, hundredths, and thousands will therefore be aided by the decimal place value. For instance, the definition of the place value tenth is 1/10.

Think about the decimal 12.345.

Tenth place value in this case is 3.

By substituting the actual number with an approximation, the decimal value can be rounded. To the nearest integer, the decimal number 5.8 is rounded to 6, for instance. The decimal number can also be rounded to the nearest tenths place value. The first integer that appears after the decimal point is the tenth place value. Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5.

Considering the quadratic equation, it is found that:

a) The initial height of the object is of 58.8 meters.

b) The object first hits the ground after 39.2 seconds.

c) The maximum height reached by the object is of: 1912 meters.

The quadratic equation that models the projectile's height is defined as follows:

s(t) = -4.9t² + 190.6t + 58.8.

Which has the coefficients given as follows:

a = 4.9, b = 190.6, c = 58.8.

The initial height is obtained as follows:

s(0) = -4.9(0)² + 190.6(0) + 58.8 = 58.8 meters.

It hits the ground at the positive root for which s(t) = 0, hence, using a quadratic equation calculator, this root is of:

t = 39.2 seconds.

The maximum height obtained by the object is the y-coordinate of the vertex, hence:

hMAX = -(b² - 4ac)/4a = -(190.6² - 4(-4.9)(58.8))/(4(-4.9)) = 1912 meters.

The minimum and maximum of the function f(x)=2x³+15x²-36x+1 are 38 and 39 respectively

The maximum value of a function f(x) is also called the absolute maximum value, or the  greatest value of the function f on the closed interval [0, 1]. on the other hand, the minimum value of f(x) at x = 0 is called the absolute minimum value,  or least value of the function f on the closed interval [0, 1)

How to find the minimum and maximum functions?

From the function f(x) = 2x3 − 15x2 + 36x + 1.

Using differential calculus , dy/dx = 6x2 - 30x + 36

= 6(x2 - 5x + 6)

f(x) is a maximum when x = 2 and the maximum value of f(x) = f(2).

This implies that f(2) = 2(23) − 15(22) + 36(2) + 11 = 39

d2y/dx2|x=3 = 12 x 3 - 30 = 6 > 0

This also implies that  f(x) is a minimum when x = 3 and the minimum value of f(x) = f(3) = 2(3)3 − 15(3)2 + 36(3) + 11 = 38

Harry bought six (6) apples and five (5) oranges from this store.

In order to write a system of linear equations to describe this situation, we would assign variables to the amount of apples and oranges respectively, and then translate the word problem into algebraic equation as follows:

Since Harry bought a total of 11 pieces of fruit, we have:

A + O = 11              .....equation 1.

Since the cost of apples is $0.80 each and oranges cost $0.95 each, we have:

0.80A + 0.95O = 9.95      .....equation 2.

From equation 1, we have:

O = 11 - A                   .....equation 3.

Substituting equation 3 into equation 2, we have:

0.80A + 0.95O = 9.95

0.80A + 0.95(11 - O) = 9.95
