Help on number 1 please!! Thanks.

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

Answer:

volume is approximately 73.6 to the nearest tenth

Step-by-step explanation:

The volume of a pipe is volume = π * radius² * length

diameter = 2.5

radius = 2.5/2 = 1.25 inches

volume = π * 1.25² * 15

volume = π * 1.5625 * 15

volume =  π * 23.4

which is approximately 73.6 to the nearest tenth

According to the concept of translation, the function of g(x) = x² + 2.

Translation:

The concept of translation is defined by using the function f(x) then f(x + a) is a horizontal translation of f(x)

If the value of a > 0 then a shift to the left of a units

If the value of  a < 0 then a shift to the right of a units

Given,

Here we have the function f(x) = x².

Now, we have to find  the equation of the graph of g(x) and how it change in corresponds to f(x).

While we looking the graph, the function f(x) has curved on the origin (0, 0).

Where the function g(x)  has curved the point (2,0).

Which tells the the graph is move left side by 2 units.

So, according to the rule of translation, the value of a is 2.

Then the function g(x) is written as,

=> g(x) = x² + 2.

Answer:8 experiments

Step-by-step explanation:

she has 8 feet of copper and she needs one foot for each experiment she can do 8 experiments.

A system of linear equations to describe this situation is given by:

A + O = 11.

0.80A + 0.95O = 9.95.

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

Apples, A = 0.90/0.15

Apples, A = 6.

For the number of oranges, we have:

Oranges, O = 11 - A

Oranges, O = 11 - 6

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.

Roman numeral representing thousand (1000)

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

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 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

So, in polar form, the points we require for the polar curve graph are

$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

x = 40

So, the amount earned by Play be, $40
