Actual answer:

The linear equation that gives the height on the x-th month is:

y = 2.5*x + 74.5

This will be modeled with a linear equation of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

Remember that for a line with the points (x₁, y₁) and (x₂, y₂), the slope is given by:

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

Here we have the two points (3, 82) and (7, 92). Where the first value is the number of months and the second value is the height.

So the slope is:

[tex]a = \frac{92 - 82}{7 - 3} = 10/4 = 2.5[/tex]

Then the linear equation is:

y = 2.5*x + b

To get the value of b, we use the fact that when x = 3, we have y = 82,

82 = 2.5*3 + b

82 = 7.5 + b

82 - 7.5 = b = 74.5

Then the linear equation is:

y = 2.5*x + 74.5

Step-by-step explanation:

Solution

Break the numbers down by the number of digits in that sequence.

Number of digits 1 to 9 =                                        9

Number of digits from 10 to 99

There are 90 numbers between 10 and 99

Each has 2 digits

Step-by-step explanation:

Using Cavalieri’s Principle, the height of the oblique cylinder with the given volume and base radius is 6cm.

Option A) is the correct answer.

From Cavalieri's principle, the volume of an oblique cylinder is expressed as;

V = base area × h

V = πr² × h

Given that;

V = πr² × h

486πcm³ = π × ( 9cm )² × h

486πcm³ = π × 81cm² × h

486πcm³ = 81πcm² × h

h = 486πcm³ / 81πcm²

h = 6cm

Using Cavalieri’s Principle, the height of the oblique cylinder with the given volume and base radius is 6cm.

Option A) is the correct answer.

The approximate original price of the car is $23032

The given parameters are:

Rate, r = 8%

Price at 4 years old = 16,500

An exponential function is represented as:

y = a(1 - r)^x

Where a represents the initial value

This gives

y = a(1 - 8%)^x

Evaluate

y = a(0.92)^x

At 4 years old, we have:

16500 = a(0.92)^4

Divide both sides by (0.92)^4

a = 23032

Hence, the approximate original price of the car is $23032

ii) acute ∠COD = 25°

iii) acute ∠BOC = 40°

iv) acute ∠AOD = 75°

From the question, we are to determine the measures of the angles

i) acute ∠AOB

From the given diagram,  

∠AOB = 10°

ii) acute ∠COD

From the given diagram,  

∠COD= 25°

iii) acute ∠BOC

From the diagram, we can write that

∠AOB+∠BOC+ ∠COD + ∠DOE = 90° (Angles at a right angle)

10° + ∠BOC + 25° + 15° = 90°

∠BOC + 50° = 90°

∠BOC = 90° - 50°

∠BOC = 40°

iv) acute ∠AOD

From the diagram,

∠AOD = ∠AOB + ∠BOC +∠COD

∠AOD = 10° + 40° + 25°

∠AOD = 75°

Answer:

4/3 = m

Step-by-step explanation:

Since you have been given the value of two points, you can use the point-slope formula to find the slope. This general structure of this formula is:

y₁ - y₂ = m(x₁ - x₂)

In this equation, "m" represents the slope, "y₁" and "x₁" represent the values in the first point, and "y₂" and "x₂" represent the values in the second point,

To find the slope, substitute the values of each point into the formula and simplify.

Point 1: (3, 5)

Point 2: (0, 1)

y₁ - y₂ = m(x₁ - x₂)                  <----- Point-slope form

5 - y₂ = m(3 - x₂)                   <----- Plug values from Point 1 into equation

5 - 1 = m(3 - 0)                      <----- Plug values from Point 2 into equation

4 = m(3 - 0)                           <----- Simplify left side

4 = m(3)                                 <----- Simplify inside the parentheses

4/3 = m                                  <----- Divide both sides by 3

Answer:

(a)  128 ft

(b)  4 s

(c)  Vertex:  (1, 144)

Step-by-step explanation:

Given information:

The height of the projectile at launch is the value of h(t) when t = 0 (the y-intercept).

Therefore, from inspection of the graph, the y-intercept is (0, 128).

So the height of the projectile at launch is 128 ft.

The length of time it took for the projectile to land is the time from the beginning (when t = 0) to when the height is 0 (the x-intercept).  

From inspection of the graph, the x-intercept is (4, 0)

So the length of time it took for the projectile to land is 4 s.

The vertex is the turning point (minimum/maximum point).

Therefore, from inspection of the graph, the vertex is (1, 144).

The vertex represents the time and height at which the projectile was at its maximum.  So at the time of 1 second, the projectile was at its maximum height of 144 ft.

I think you may have made a typo, as it is extremely unlikely that a trashcan is 314 feet tall.  I will assume that you meant 3.14 feet.

Step-by-step explanation:

We already have the base, so we can already cut out one step.  If we were not given the base, however, we would simply multiply the length by the width of the prism.  Next we multiply the base by the height (3 X 3.14) to get the volume of the prism, 9.42 cubic feet.  In the case that there was no typo, and 314 was the correct height, the volume would be 942 cubic feet.

math is fun

The values of x in both figures are 45 and 34, respectively.

Start by calculating the angle CAB using:

CAB + ABC + BCA = 180 --- angles in a triangle

The triangle is an isosceles triangle.

So, we have:

CAB + ABC + CAB = 180

Evaluate

2CAB + 25 + 75 = 180

This gives

CAB = 40

Calculate angle BEA using:

BEA + CAB + ABE = 180 --- angles in a triangle

This gives

BEA + 40 + 25 = 180

Evaluate

BEA = 115

Vertical angles are equal.

So, we have:

CED = BEA = 115

Calculate angle EDC using:

EDC + CED + DCE = 180 --- angles in a triangle

This gives

EDC + 115 + 30 = 180

Evaluate

EDC = 35

Opposite angles of quadrilaterals add up to 180.

So, we have:

x + EDC + ABC = 180

This gives

x + 35 + 25 + 75 = 180

Evaluate

x = 45

Hence, the value of x is 45

Start by calculating the angle DEC using:

DEC + CDE + EED = 180 --- angles in a triangle

This gives

DEC + 18 + 30 = 180

Evaluate

DEC  = 132

Vertical angles are equal.

So, we have:

AEB = DEC = 112

Calculate angle EAB using:

EAB + AEB + ABE = 180 --- angles in a triangle

This gives

EAB + 112 + 42  = 180

Evaluate

EAB  = 26

Triangle ABC is an isosceles triangle.

So, we have:

BCE = EAB  = 26

Calculate angle CBE using:

CBE + BCE + CEB = 180 --- angles in a triangle

Where CEB = 180 - DEC --- angle on a straight line

So, we have:

CBE + BCE + 180 - DEC = 180

This gives

CBE + 26 + 180 - 112 = 180

Evaluate

CBE  = 86

Opposite angles of quadrilaterals add up to 180.

So, we have:

x + EDC + ABC = 180

This gives

x + 18 + 42 + 86 = 180

Evaluate

x = 34

Hence, the value of x is 34
