A 15 ft ladder makes a 52° angle with the ground. How far will the top of the ladder be above the ground.

Answers

Answer:

11.820 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

Sin = Opposite/Hypotenuse

The length of the ladder is the hypotenuse of a right triangle with 52° as the base angle. The side opposite is the height up the building where the top of the ladder rests. So, you have the relation ...

sin(52°) = height/(15 ft)

Multiplying by the denominator gives you ...

height = (15 ft)·sin(52°) ≈ 11.820 ft

Marti has a jar of 161 coins consisting of pennies and nickels. The total value of the coins is $3.09. How many nickels does Marti have in the jar

Answers

Okay, so there are nickels and pennies in this jar.

So, let's call the number of pennies X

Since there are 161 coins altogether, the number of nickels is (161 - X)

So now we solve the equation:

.01X + .05(161 - X) = 3.09

.01X + 8.05 - .05X = 3. 09

4.96 = .04X

124 = X

So, there are 124 pennies

Therefore, there are 161 - 124 = 37 nickels

Let's check our answer:

124 x .01 + 37x .05 = 1.24 + 1.85 = 3.09

It works!

I think it is 18

nickels for $3.09

These are two angles that add up to 180° that share a common vertex. What do you call these angles?

Answers

Answer:

• linear angles

• supplementary angles (all linear angles are supplementary)

Step-by-step explanation:

If the angles share a side and are measured in opposite directions from that side, the non-common edges of these angles form a straight line, so these angles are sometimes called "linear" angles.

Since their sum is 180°, they are always "supplementary" angles. (Supplementary angles need not share a vertex or a side.)

What are the solutions of the equation 9x4 – 2x2 – 7 = 0? Use u substitution to solve.x = + √7/9 and x = ±1 x = + √7/9 and x = ±i x = +i √7/9 and x = ±1 x = +i √7/9 and x = ±I 

Answers

Answer:

Step-by-step explanation:

9x⁴ – 2x² – 7 = 0

Let's say that u = x²:

9u² – 2u – 7 = 0

Factor:

(u – 1) (9u + 7) = 0

u = 1, -7/9

Since u = x²:

x² = 1, -7/9

x = ±1, ±i √(7/9)

By using the substitution method, the solutions of this equation (polynomial) is equal to C. x = ±1 and ±i√(7/9).

How to determine the solutions of an equation?

In order to determine the solutions of this equation (polynomial), we would let "u" be equal to x² and then substitute this value into the equation as follows:

9x⁴ - 2x² - 7 = 0

Substituting the value of "u" into the equation (polynomial), we have:

9u² - 2u - 7 = 0

Factorizing the equation (polynomial), we have:

(9u + 7)(u - 1) = 0

u = 1 and -7/9

Since, u = x²:

x² = 1 and -7/9

x = ±√(1 and -7/9)

x = ±1 and ±i√(7/9).

mariela is standing in a building and looking out a window at a tree. The tree is 20 feet away from Mariela, Mariela's line of sight creates a 42 degree angle of elevation, and her line of sight creates a 31 degree of depression. What is the height, in feet, of the tree?

Answers

Answer: 30.01 feet.

Step-by-step explanation:

You need to remember this identity:

[tex]tan\alpha=\frac{opposite}{adjacent}[/tex]

Observe the figure attached, where [tex]h_t[/tex] is the height in feet of the tree.

You need to calculate [tex]h_1[/tex] of the Triangle 1, where:

[tex]\alpha= \alpha_1=42\°\\opposite=h_1\\adjacent=20[/tex]

Substitute values into [tex]tan\alpha=\frac{opposite}{adjacent}[/tex] and solve for [tex]h_1[/tex]:

[tex]tan(42\°)=\frac{h_1}{20}\\\\h_1=20*tan(42\°)\\h_1=18[/tex]

Now you need to calculate [tex]h_2[/tex] of the Triangle 2, where:

[tex]\alpha= \alpha_2=31\°\\opposite=h_2\\adjacent=20[/tex]

Substitute values into [tex]tan\alpha=\frac{opposite}{adjacent}[/tex] and solve for [tex]h_2[/tex]:

[tex]tan(31\°)=\frac{h_2}{20}\\\\h_2=20*tan(31\°)\\h_2=12.01[/tex]

Then the height in feet of the tree is:

[tex]h_t=h_1+h_2\\h_t=(18+12.01)ft\\h_t=30.01ft[/tex]

The height of the tree can be determined by the trigonometric ratio of tan angle.

The height of the tree is 30 feet.

Given that,

Mariela is standing in a building and looking out a window at a tree.

The tree is 20 feet away from Mariela,

Mariela's line of sight creates a 42-degree angle of elevation, and her line of sight creates a 31 degree of depression.

We have to determine,

What is the height, in feet, of the tree?

According to the question,

Let, the height of the tree be h

The tree is 20 feet away from Mariela,

First, we have to calculate the length of BD which is x,

Then,

The length of BD is given by,

[tex]\rm Tan\theta = \dfrac{Opposite \ side}{Adjacent \ side}\\\\Tan\theta = \dfrac{BD}{AD}\\\\Tan42 = \dfrac{x}{20}\\\\x = tan42 \times 20\\\\x = 0.9 \times 20\\\\x = 18[/tex]

The measurement of x is 18 feet.

Again we have to calculate the length of y,

Then,

The length of DC is given by,

[tex]\rm Tan\theta = \dfrac{Opposite \ side}{Adjacent \ side}\\\\Tan\theta = \dfrac{DC}{AD}\\\\Tan31 = \dfrac{Y}{20}\\\\y = tan31 \times 20\\\\x =0.6 \times 20\\\\y = 12[/tex]

The measurement of y is 12 feet.

Therefore,

The height of the tree is given by,

[tex]\rm h= x +y\\\\h = 18+12\\\\h = 30 \ feet[/tex]

Hence, The height of the tree is 30 feet.

A) How long does it take for it to rotate 225 degrees?

B) How long does it take to rotate 9π radians?

C) The diameter of the Earth is approximately 7920 miles. How far will a point on the equator rotate in 2 hours?

Answers

Answer:

A)

15 hours

B)

108 hours

C)

2074.29 miles

Step-by-step explanation:

Under the assumption the earth is a perfect circle, then in one complete rotation about its axis ( 24 hours) the Earth will cover 360 degrees or 2π radians.

A)

In every 24 hours the earth rotates through 360 degrees ( a complete rotation). We are required to determine the length of time it will take the Earth to rotate through 225 degrees. Let x be the duration it takes the earth to rotate through 225 degrees, then the following proportions hold;

(24/360) = (x/225)

solving for x;

x = (24/360) * 225 = 15 hours

B)

In 24 hours the earth rotates through an angle of 2π radians (a complete rotation) . We are required to determine the length of time it will take the Earth to rotate through 9π radians. Let x be the duration it takes the earth to rotate through 9π radians, then the following proportions hold;

(24/2π radians) = (x/9π radians)

Solving for x;

x = (24/2π radians)*9π radians = 108 hours

C)

If the diameter of the earth is 7920 miles, then in a day or 24 hours a point on the equator will rotate through a distance equal to the circumference of the Earth. Using the formula for the circumference of a circle;

circumference = 2*π*R = π*D

                         = 7920*3.142

                         = 24891.43 miles

Therefore a point on the equator covers a distance of 24891.43 miles in 24 hours. This will imply that the speed of the earth is approximately;

(24891.43miles)/(24 hours) = 1037.14 miles/hr

The distance covered by the point in 2 hours will thus be;

1037.14 * 2 = 2074.29 miles

vertex = (- 3, 24)

Step-by-step explanation:

Given a quadratic in standard form y = ax² + bx + c : a ≠ 0, then

The x- coordinate of the vertex is

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

y = - x² - 6x + 15 ← is in standard form

with a = - 1, b = - 6, thus

[tex]x_{vertex}[/tex] = - [tex]\frac{-6}{-2}[/tex] = - 3

Substitute x = - 3 into the function for corresponding value of y

y = - (- 3)² - 6(- 3) + 15 = - 9 + 18 + 15 = 24

True.

The solution to the given equation 4x + 7 = 31 is x = 6, which is determined by subtraction.

The equation is given as follows:

4x + 7 = 31

To solve the equation 4x + 7 = 31 for x, we want to isolate the variable x on one side of the equation.

First, we can begin by subtracting 7 from both sides of the equation:

4x + 7 - 7 = 31 - 7

Simplifying, we get:

4x = 24

Next, we want to isolate x, so we divide both sides of the equation by 4:

4x/4 = 24/4

This simplifies to:

x = 6

Step-by-step explanation:

Let's factor this the "old fashioned" way.  The standard form of a quadratic is

[tex]y=ax^2+bx+c[/tex]

If you're familiar with the quadratic formula I'd say throw it into that, but if not, again, let's do it the "old fashioned" way.  

We need to find the product of our a and c.  Our a = 2 and our c = -3.  So that gives us a -6.  Now we have to find the factors of 6 (the negative right now doesn't matter so much).  The factors of 6 are 1, 6  and 2, 3.  Both of those possibilities will work to give us a +5, which is the linear term.  Puttng in the 2, 3 first:

[tex]0=2x^2+3x+2x-3[/tex]

Now group the terms together into groups of 2:

[tex]0=(2x^2+3x)+(2x-3)[/tex]

The idea is to factor out something common in each term so that what's left over in the parenthesis in both terms is exactly the same.  In the first term we can factor out a common x, and in the second term, the only thing common is a 1.  So that looks like this:

[tex]x(2x+3)+1(2x-3)[/tex]

What's inside those parenthesis are not actually identical, so 2 and 3 won't work.  Lets try 1 and 6.  For those 2 numbers to equal a +5, the 6 is positive and the 1 is negative.  So let's try that:

[tex](2x^2+6x)+(-x-3)[/tex]

In the first term we can factor out the common 2x and in the second term we can factor out the common -1:

2x(x + 3) - 1(x + 3)

Now what's common is (x + 3), so we can factor THAT out and what is left over is 2x - 1:

(x + 3)(2x - 1) = 0

If x + 3 = 0, then x = -3

and if 2x - 1 = 0, then 2x = 1 and x = 1/2

Arithmetic is a branch of mathematics that studies numbers and the many operations that may be applied to them. The four basic math operations are addition, subtraction, multiplication, and division.

The given expression is;

[tex]\frac{(2)^3(2)^4}{2^{10}}[/tex]

Step 1; Multiplication rule of exponents;

[tex]\frac{(2)^3(2)^4}{2^{10}} \\\\ \frac{2^{3+4}}{2^{10}} \\\\\frac{2^7}{2^{10}}[/tex]

Step 2;Division rule of exponents;

[tex]\frac{2^7}{2{10}} \\\\ (2)^{7-10}\\\\ (2)^{-3}[/tex]

Step 2;Inverse rule of exponents;

[tex](2)^{-3}\\\\ \frac{1}{2^3} \\\\\frac{1}{8}[/tex]

Hence, the rule of exponents was applied in each step will be multiplication rule,division rule and inverse of exponent rule.

Which equation matches the graph?

Answers

Answer:  D) -2 |x| - 2

Step-by-step explanation:

A v-shaped graph is an absolute value graph.  

The general form of an absolute value equation is: y = a |x - h| + k

where (h, k) represents the vertex and "a" represents the vertical stretch (aka slope).  

The vertex of the given graph is (0, 2), however the graph is inverted (upside-down) which is a reflection across the x-axis.  Therefore,

a = -2(h, k) = (0, -2)                    --> y = -2 |x| - 2

Which correspondence is equivalent to Δ PQR↔ΔSTU?

A) Δ RQP ↔ ΔUTS?

B) Δ PRQ ↔ ΔTUS?

C) Δ RPQ ↔ ΔSUT?

D) Δ QRP ↔ ΔUST?

Answers

Answer:

A) Δ RQP ↔ ΔUTS

Step-by-step explanation:

Answer:

Option A) is correct

Step-by-step explanation:

Given : [tex]\Delta PQR \leftrightarrow  \Delta STU[/tex]

We need to find which correspondence is equivalent to [tex]\Delta PQR \leftrightarrow  \Delta STU[/tex] .

Solution :

One to one correspondence means measure of each side and each angle of one triangle is equal to the side and angle of the other triangle .

Here, we observe that option A) is equivalent to [tex]\Delta PQR \leftrightarrow  \Delta STU[/tex] as explained below :

As per [tex]\Delta PQR \leftrightarrow  \Delta STU[/tex] ,

[tex]PQ=ST\,,\,QR=TU\,,\,PR=SU\\\angle P=\angle S\,,\,\angle Q=\angle T\,,\,\angle R=\angle U[/tex]

Also, as per [tex]\Delta RQP \leftrightarrow  \Delta UTS[/tex] , we have

[tex]PQ=ST\,,\,RQ=UT\,,\,PR=SU\\\angle P=\angle S\,,\,\angle Q=\angle T\,,\,\angle R=\angle U[/tex]

Therefore,

[tex]\Delta RQP \leftrightarrow  \Delta UTS[/tex] is equivalent to [tex]\Delta PQR \leftrightarrow  \Delta STU[/tex]

So, option A) is correct .

Answer:

262 m³

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = [tex]\frac{1}{3}[/tex] πr²h ( r is the radius of the base and h the height )

here diameter = 10 m, hence radius = 5 m

V = [tex]\frac{1}{3}[/tex]π × 5² × 10

   = [tex]\frac{1}{3}[/tex] π × 250 = [tex]\frac{250\pi }{3}[/tex] ≈ 262 m³

A rectangular prism has a volume of 64 cubic inches. what are the possible dimensions?

Answers

You can solve this by using trial and error. When doing so I came with a conclusion of 8,4, and 2.

Final answer:

The dimensions of a rectangular prism with a volume of 64 cubic inches can be any combination of length, width, and height whose multiplication result is 64, including possibilities of 1x1x64, 2x2x16, 4x4x4 and many more.

Explanation:

The volume of a rectangular prism is calculated by multiplying the length, width, and height of the prism (Volume = Length x Width x Height).

If we know that the volume of the prism is 64 cubic inches, there can be several possible dimensions for the rectangular prism. To find these, we would look for different combinations of length, width and height that when multiplied, equal 64. Here are a few examples:

Length = 1 inch, Width = 1 inch, Height = 64

Length = 2 inches, Width = 2 inches, Height = 16 inches

Length = 4 inches, Width = 4 inches, Height = 4 inches

There can be many more possible dimensions, including fractions as well.
