Step-by-step explanation:

f(x) = −3/2(x+1)(x−5) = -3/2 (x²-4x-5) = -3/2 (x²-4x+4-9) = -3/2 ((x-2)² - 9)

f(x) = -3/2 (x-2)² + (-3/2)*(-9) = -3/2 (x-2)² + 13.5

Answer:

373737373737373383847484

This equation is in the form y = mx + b and when a function

is written in this form, we know that it's a linear function.

Another way to tell that it's a linear function is

that the variable is raised to the first power.

Step-by-step explanation: cant contain division by a variable in a polynomial

Answer: (0,2) and (0, -8)

Step-by-step explanation:

Step-by-step explanation:

Given

f(x) = 5 / 2x - 1

f^-1( x) = ?

Let

y = f(x)

y = 5/2x - 1

Interchanging the roles of x and y we get

x = 5/2y - 1

2y - 1 = 5/x

2y = 5/x - 1

y = (5/x - 1)/ 2

f^-1(x) = ( 5/x - 1) / 2

Step-by-step explanation:

Answer:

m(arc QT) = 142°

m(arc STR) = 314°

Step-by-step explanation:

"Measure of intercepted arc is double of the inscribed angle"

From the picture attached,

Measure of inscribed angle QST = 71°

Therefore, measure of arc QT = 2 × Measure of angle QST

                                                  = 2(71°)

                                                  = 142°

Since, m(arc SR) + m(arc STR) = 360°

46° + m(arc STR) = 360°

m(arc STR) = 360° - 46°

                  = 314°

Step-by-step explanation:

3x+2x=180

5x=180

x=36°

Answer:

2.56

Step-by-step explanation:

100%->23.86

15%-> 3.579

3.579+23.86=27.439(how much he needs to pay including tip)

30-27.439=2.561

                ≈2.56 (since we dont usually pay up to 3 d.p.)

The answer for number 1 is 1.72. The answer for number 2 is 4.83.

So for number one, the first thing you need to do is determine how many sides are on the first shape. Since it is a pentagon, and one pentagon has 5 sides, then you use the following formula to determine the volume of a[tex]V = \frac {1}{4} \times \sqrt{5 \times (5 +2 \times \sqrt {5})} \times (10)^{2} \times 10[/tex] pentagon: [tex]\alpha = \frac{1}{4} \times \sqrt[]{5(5+2 \sqrt[]{5}) \alpha ^{2} }[/tex] And in this case, the area would be 1.72, because if you insert the side lengths, the equation would look like this: [tex]V = \frac {1}{4} \times \sqrt{5 \times (5 +2 \times \sqrt {5})} \times (10)^{2} \times 10[/tex] , which if you solve this equation, then you will end up with the answer of 1.72.

For number two, the first thing you need to do is determine how many sides are on the second shape. Since it is an octagon, and the prefix oct means 8, the number of sides on the shape is 8. If the perimeter is 64, and there are 8 sides, you can divide 64 by 8 to get 8. The equation to solve for the area should look like this: [tex]V = 2(1 + \sqrt{2}) \times s^{2} \times h[/tex]. Now all you need to do is insert the side lengths to the proper places. It should then look like this: [tex]V = 2(1 + \sqrt{2}) \times 8^{2} \times 8[/tex], after you solve the equation, you should end up with 4.83.

Answer:

A = 8/9

Step-by-step explanation:

Area of Rectangle = Length (Width)

A = lw

A = (4/9) (2)

A = (4/9) (2/1)

A = 8/9

Answer:

This is nothing related to real life. The only thing is it helps with trigometry, programming shapes, and so on

Step-by-step explanation:

Answer:

Yes.

The first has an area of 9, so each side is three.

The second has an area of 16, so each side is four.

Each side of the third square is given as 5.

So the triangle has sides of 3, 4, and 5.

3²+4²=5²

9+16=25

25=25 It works given the Pythagorean theorem.

Step-by-step explanation:

Yes.

The first has an area of 9, so each side is three.

The second has an area of 16, so each side is four.

Each side of the third square is given as 5.

So the triangle has sides of 3, 4, and 5.

3²+4²=5²

9+16=25

25=25 It works given the Pythagorean theorem.

Answer:

a

Step-by-step explanation:

Answer: t1 = -34; t2 = -64; t3 = -94

d is the distance between numbers (d > 0)

we have:

t5 = t1 + 4d = -154

t9 = t1 + 8d = -274

we have the equations:

t1 + 4d = -154

t1 + 8d = -274

<=> t1 = -34

      d = -30

with t1 = -34 and = -30 => t2 = -34 - 30 = -64

                                          t3 = -64 - 30 = -94
