The length of f of the triangle is f = 11.7 cm

The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.

The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:

c² = a² + b² - 2ab cos(C)

where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.

Given data ,

Let the triangle be represented as ΔEFG

And , the measures of the sides of the triangle are

g = 4.3 cm

e = 9.1 cm

And , measure of angle ∠F = 116°

where c² = a² + b² - 2ab cos(C)

On simplifying , we get

a² = c² - b² + 2abcos ( C )

78.26 ( cos 116° ) - 4.3² - 9.1² = f²

f² = 135.7344

Taking square roots on both sides , we get

f = 11.7 cm

Hence , the length is f = 11.7 cm

Answer:

(3x+2)(x+4)

Step-by-step explanation:

(3x+2)(x+4) = (3x)(x) + (3x)(4) + (2)(x) + (2)(4)

= 3x² + 12x + 2x + 8 *****

= 3x² + 14x + 8

You start by figuring it will be in the form of (3x + a)(x + b) because 3 doesn't factor. The two middle terms in the line followed by the stars must add up to 14x. And in (3x + a)(x + b), ab must be equal to the 8 on the end (the constant factor).

For most people, factoring takes a LOT of practice. And somethimes you just have to try a lot of factors before you hit the right combination. But if you do it enough, it really does get easier to 'see' the answer a lot of the time.

Answer:

Ali 25

Beth 15

Clare 32

Step-by-step explanation:

Here, we want to get the score of the three

let Ali’s score be x

He scored 10

more than Beth; Beth score will be x-10

Let us now work with the ratio

x/x-10 = 5/3

3x = 5(x-10)

3x = 5x - 50

5x-3x = 50

2x = 50

x =

50/2

x = 25

Beth will

score 25-10 = 15

score had 7 more than Ali,

25 + 7 = 32

The question is incomplete. Here is the complete question.

Mr. Jackson decides to build a planter in the shape of a cube fo rhis wife. The top of the planter will be open so his wife can plant and water her flowers. The perimeter of the bottom of the planter is 12 feet.

How many square feet of material does Mr Jackson need to build the planter?

(a) 27 square feet

(b) 45 square feet

(c) 60 square feet

(d) 720 square feet

Answer: 45 square feet

Step-by-step explanation: A cube is a regular solid with six square faces.

Square is a quadrilateral with 4 right angles and 4 equal sides. So a cube is solid formed by 6 squares.

Perimeter is the sum of all the sides. For a square, perimeter is given by

P = 4s

Then, side of the bottom is

[tex]s=\frac{P}{4}[/tex]

[tex]s=\frac{12}{4}[/tex]

s = 3

Area of a square is

[tex]A=s^{2}[/tex]

[tex]A=3^{2}[/tex]

A = 9

The planter is a cube with 5 faces, because the top is open. Then, total area is

[tex]A_{t}=9+9+9+9+9[/tex]

[tex]A_{t}=[/tex] 45

Mr Jackson will need 45 square feet of material to build the planter.

Answer:

D. c(p) = 0.42p

Step-by-step explanation:

total cost = .42(P)

Example: 5 lbs

$2.10 = $.42(5)

c(p) = 0.42p <== ur function

Since a pound of sugar increases proportionally to the total cost of sugar bought, then the function can be written as:

c(p) = 0.42p

Where: c(p) = total cost of sugar bought

p = pounds of sugar

c(p) is a function of p, because c(p) depends on p.

Answer: The function rule that gives the total cost is given by

Step-by-step explanation:

Let the number of pounds of sugar be 'p'.

Let the total cost would be C(p).

Cost of each pound = $0.42

So, the function rule would be

Hence, the function rule that gives the total cost is given by

Step-by-step explanation:

John said he can find 38×10 by adding a 0 to the end of 38 to get 380. John finds 46.52×10 using the same method and gets 46.520.

For the first one that is, 38 × 10 = 380, John is correct. For the second one, that is, 46.52 × 10 = 46.520. John is incorrect. In this case, the first one is correct because John was multiplying by a whole number.

For the second one involving a decimal, John could have shifted the decimal point one place to the right and not add 0 to the end. Then he will get:

46.52 × 10 = 465.2

Answer vary :

2.95(21 times 39) = $2,416.05

Step-by-step explanation:

honestly in my opinion that the answer. so we’re trying to find out how much money the school will earn.

if each seat cost 2.95 we need to find out how many seats are their?

-21 times 39 = 819

we multiplied the rows and seats find out how many seats their are and the answer is 819.

after you do that now we have to find out how much money they will earn from selling all 819 seats.

-819 times 2.95 = 2,416.05

we then multiplie all of the seats wich is 819 seats by 2.95 wich is the cost of one seat and got 2,416.05, and that’s the answer we’ve been looking for.

and that’s how I got my answer.

The total money school will get is £2416.05 on a play.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

A ticket for a seat at a school play costs £2.95

There are 21 rows of seats.

There are 39 seats in each row.

That means,

there are total 21 x 39 =  819 seats.

So, the total money the school will get,

= 819 x £2.95

= £2416.05

Therefore, school makes £2416.05 on a play.

(x, y) → (x+2, y+3) means a translation 2 units to the right and 3 units up.

Transformations are changes done in the shapes on a coordinate plane by rotation, reflection or translation.

here, we have,

Given the rule of transformation:

(x, y) → (x+2, y+3)

If we move horizontally 2 units to the right, 2 is added to the x-coordinate of any given point, and then 3 units up.

In other words,

(x, y) → (x+2, y+3) means Translation 2 units right and 3 units up.

For example,

Let say if we have the point A(4, 5)

Using the translation rule:

(x, y) → (x+2, y+3)

A(4, 5) → A'(4 + 2, 5 + 3) → A'(6, 8)

Therefore, the new position of A(4, 5) after translating 3 units right and 2 units up would be: A'(6,8).

Hence, (x, y) → (x+2, y+3) means a translation 2 units to the right and 3 units up.
