Find the three trigonometric..pls help due very soon

Answer:

(4a - 11b)(4a + 11b)

Step-by-step explanation:

16a² - 121b² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

16a² - 121b²

= (4a)² - (11b)²

= (4a - 11b)(4a + 11b)

Answer:

Step-by-step explanation:

Rule: (a^2-b^2)=(a-b)(a+b) (‘difference of squares’)

16a^2-121b^2

(4a-11b)(4a+11b)

Answer:

20x+4.99=y

Step-by-step explanation:

Each sweatshirt cost $20, but we don't know how many sweatshirts someone will buy so we use X, representing the amount of sweatshirts. There is a shipping charge of $4.99, so we have to add that to the cost of the sweatshirts. 20x+4.99. Y is the total cost.

the answer is 3x^3 +13x^2 +6x -8.

Answer:

I can simplify it for u but not sure the product

3x(x²+3x-2)+4(x²+3x-2)

3x³+9x²-6x+4x²+12x-8

=3x³+13x²+6x-8

that's the final answer

Answer:

x = 3.6

Step-by-step explanation:

Since, ABCD ~ EFGH

Therefore, all interior angles of both the quadrilaterals will be equal and the corresponding sides of both quadrilaterals will be proportional.

[tex]\frac{AD}{EH}=\frac{AB}{EF}[/tex]

[tex]\frac{x}{2.4}=\frac{3}{2}[/tex]

x = [tex]\frac{3\times 2.4}{2}[/tex]

x = 3.6

Step-by-step explanation:

A graph of the points reveals one pair of parallel sides: a trapezoid.

Answer:

A

Step-by-step explanation:

The line stays straight because of the y placement being 1

Answer:

{(2, 1), (5, 1), (6, 1)}

Step-by-step explanation:

A linear function shows as a straight line.

Option A's y-values are the same. If graphed, it would form a horizontal line.

See graph below.

Option A should be the correct answer.

Answer: 463.96 mm² or 46.4 cm²

Step-by-step explanation:

Quarters are circular in shape so the surface area of one side will be the area of a circle.

Area of a circle = π * r²

Radius = Diameter / 2

= 24.3 / 2

= 12.15 mm

Area = 22/7 * 12.15²

= 463.96 mm²

Answer:

m=1/4

Step-by-step explanation:

5m+2-m=12m

4m+2=12m

2=12m-4m

2=8m

2/8=m

1/4=m

m=1/4

Answer:

A= $1406

Step-by-step explanation:

The formula for simple interest is A=P(1+rt), where P=Principal, R=Rate, and T=Time. Before you plug your numbers into your formula, you must first convert 12% to a decimal (This is simple because all you have to do is divide 12 by 100.)- 0.12.

Now, you can plug your numbers into the formula: A=950(1+0.12x4). To make this less complex, I suggest working in the parenthesis first- specifically simplifying rt, or multiplying 0.12 by 4 (you should get 0.48)! Now, you are just about ready to go. A=950(1+0.48)- You can plug this into your calculator as is, or you can go on ahead and add the numbers in the parenthesis if that makes you feel better! (You should get 1.48).

Your final formula should be 950(1.48), and you should plug this into a TEACHER-APPROVED CALCULATOR to save time!

Your final answer should be $1406, otherwise you did something wrong! XD!

Answer:

80cm. I think please be right

Answer:

78.5 inches

Step-by-step explanation:

A=(pi)r^2

divide diameter by 2 to get radius

radius = 5

3.14(5)^2 = 78.5

Solved for the value of y and found that y = 5.

In the Pythagorean theorem, the sum of the squares of the sides of a right-angled triangle is equal to the square of the longest side i.e, the hypotenuse of the triangle.

z² = x² + y²

The given triangle is a right-angled triangle. This means that we can use the Pythagorean theorem.

∴ y² + 12² = 13²

⇒ y² + 144 = 169

⇒ y² = 169-144

⇒ y² = 25

⇒ y = 5

Therefore, we have solved for the value of y and found that y = 5. The correct answer is option C.

Step-by-step explanation:

VX = 4 spaces

UW = 3 spaces

The angles of a triangle always add up to 180°.

By simply adding the angles and checking the total, you can tell if they make a triangle or not.

Using this property, 5 won't make a triangle, 6 will.

Answer:

27.5

Step-by-step explanation:

1/4 of $50 is $12.5. 1/5 of $50 is $10. 12.5 + 10= 22.5. So, $50-22.5= $27.5

Answer:
