Answer:

y = 17x-67

Step-by-step explanation:

The one point form of line also called slope point form is given by

[tex](y-y_1)=m(x-x_1)[/tex]

where (x1, y1) is the point and m is slope

Given: (x1, y1) = (4,1) and m= 17

Substituting these values in above equation to find equation in point-slope form

(y-1)=17(x-4)

y-1 = 17x-68

y = 17x-67

the point -slope form of equation y = 17x-67

All 3 backpacks are equal in weight, there is none that is heavier or lighter than the others. That is, the 3 backpacks have the same weight.

Step-by-step explanation:

Given that An's backpack weighs as much as Lin's backpack, and Clare's backpack weighs as much as Lin's backpack, to determine whose backpack weighs the most and whose backpack weighs the least the following mathematical reasoning must be considered:

A = L

C = L

Therefore, A = C.

Since all 3 backpacks are equal in weight, there is none that is heavier or lighter than the others. That is, the 3 backpacks have the same weight.

Step-by-step explanation:

Using pythagoras theorem

a^2 =b^2 +c^2

a always is the hypotenuse (the opposite side to the 90 angle)

b and c are the other sides obviously

So here we have a = 38

let b =11

So for c =sqrt(38^2 - 11^2)=36.373

Step-by-step explanation:

Br₂ does not equal to Avogadro's number. Since bromine is a diatomic element.

What is a diatomic element?

Diatomic molecules—so named because they only contain two atoms of the same or different chemical elements—are molecules that are made up of two atoms. A diatomic molecule is considered to be homonuclear if it contains two atoms of the same element, such as oxygen (O₂) or hydrogen (H₂).

Each bromine molecule consists of 2 atoms of bromine. Br₂ consists of two moles. One mole of bromine consists of 6.02214076 × 10²³ atoms. Thus 2 moles of bromine consist of 2 × 6.02214076 × 10²³ = atoms. Thus Br₂ does not equal to Avogadro's number.

Therefore, the measures of those two angles are 33° and 24°.

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which means "corner," is the source of the English term "angle."

Geometry is a branch of mathematics that studies the sizes, shapes, positions, angles, and dimensions of things.

We know, the sum of the angles in a triangle is always 180 degrees.

126 + x + y = 180

x + y = 54

Given that the two angles are in a ratio of 11:16, the proportion:

x/y = 11/16

Solving for x and y, we get:

x = 11y/16

We substitute this equation into the equation x + y = 54 and we get:

11y/16 + y = 54

Solving for y we get y = 24. Then we can use the proportion to find x:

x = 11 * 24 / 16 = 33.

So the two angles are 33° and 24°.

Sara's mom average speed is 66mph. The next step is to divide the distance by the time: 33/0.5 = 66 mph.

You may estimate the average pace at which an object will go a distance by looking at its average speed. Average speed is calculated by dividing a quantity by the time required to obtain that quantity.

Finding the distance and the time is necessary to calculate speed.

In this situation, you must deduct mile marker 88 from 121 to determine the distance.

121 - 88 = 33mile

Even though the time is 30 minutes, you're probably interested in miles per hour. 30 minutes must be converted to 0.5 hours.

The next step is to divide the distance by the time: 33/0.5 = 66 mph.

Answer:

The first person is about 4327.76 feet away from the island.

Step-by-step explanation:

We can draw a diagram to represent the situation. This is attached below.

Essentially, we want to find the value of x.

We are given that ∠A is 37° and ∠B is 55°.

The interior angles of a triangle must total 180°. Hence:

[tex]m\angle A+m\angle B+m\angle C=180[/tex]

Substitute:

[tex](37)+(55)+m\angle C=180[/tex]

Thus:

[tex]\displaystyle m\angle C=88^\circ[/tex]

We are also given that the length of the bridge is 5,280 feet. Since we want to find x, we can use the Law of Sines:

[tex]\displaystyle \frac{\sin(A)}{a}=\frac{\sin(B)}{b}=\frac{\sin(C)}{c}[/tex]

The variables do not really matter. It is more important that we align the angles with their respective (i.e. opposite) sides.

The respective side to ∠C is AB which measures 5280.

The respective angle to x is ∠B, which is 55°.

Hence:

[tex]\displaystyle \frac{\sin(55)}{x}=\frac{\sin(88)}{5280}[/tex]

Solve for x. Cross-multiply:

[tex]x\sin(88)=5280\sin(55)[/tex]

Thus:

[tex]\displaystyle x=\frac{5280\sin(55)}{\sin(88)}[/tex]

Use a calculator:

[tex]\displaystyle x\approx 4327.76\text{ feet}[/tex]

The first person is about 4327.76 feet away from the island.

Answer:

area = 289.24 units²

Step-by-step explanation:

divide the polygon into 9 equal triangles

the top angle of a triangle will be 360°/9 = 40°

the sides of a triangles are both 10 units

The base of a triangle is 6.84 units

the height of a triangle is:

cos 20° = height/10

0.9397 = height/10

height = 9.4 units

The area of a triangle = 1/2(6.84)(9.4) = 32.13 units²

the polygon is made from 9 of these triangles, so 9 x 32.13 = 289.24 units²

A reflex angle is an angle which measures more than 180 degrees and less than 360 degrees.

There are different types of angles in geometry, such as obtuse, acute and right angles, which all are under 180 degrees.

Assume, z is an acute or obtuse angle, and r is the reflex angle, then:

z + r = 360

r = 360 - z

Therefore, we can find the related reflex angle(r), if we know the value of the acute or obtuse angle(z).

A reflex angle equals the summation of 180 degrees and any of the primary angles (acute, right and obtuse angles). Therefore,

Reflex angle = 180° + Acute angle

Reflex angle = 180° + Right angle

Reflex angle = 180° + Obtuse angle

Answer:

7 packets of grass seed

Step-by-step explanation:

First, find the area of the circular lawn using the formula, A = [tex]\pi[/tex]r²

If the diameter is 20 meters, the radius is 10 meters.

Plug in 10 as the radius and solve for the area:

A = [tex]\pi[/tex]r²

A = [tex]\pi[/tex](10²)

A = 100[tex]\pi[/tex]

So, the area of the lawn is 100[tex]\pi[/tex] m² or approximately 314.16 m²

Divide this by 50 to find how many packets of grass seed are needed:

314.16/50

= 6.28

Round this up to 7, since we need to have a whole number answer.

So, 7 packets of grass seed have to be bought.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

We are Given θ is an angle in standard position.

Its terminal side passes through the point (12, -5).

To find the exact value of secθ in simplest radical form.

When θ is an angle in standard position and its terminal side passes through the point (x,y), then the exact value of secθ is:

So, we have x = 12 and y = -5 which is in the first quadrant.

Therefore,

r² = x² + y²

r² = ( 12 )² + ( -5 )²

r² = 144 + 25

r² = 169

r = 13
