Answer:

QST = 2x= 2*20 = 40°

Step-by-step explanation:

RSQ+QST= RST

we know that RST is 124

So,

84+2x= 124

Bringing 84 to the other side it becomes negative

2x= 124-84

= 40

Therefore,

x= 40/2

= 20 °

[tex]12x^2+5x-2=\\\\(4x-1)(3x+2)[/tex]

You can check this by working backwards and expanding:

[tex](4x-1)(3x+2)=\\\\12x^2-3x+8x-2=\\\\12x^2+5x-2[/tex]

Answer:

y = 2(x - 1)² - 3

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (1, - 3), thus

y = a(x - 1)² - 3

To find a substitute (- 1, 5) into the equation

5 = a(- 1 - 1)² - 3

5 = (- 2)²a - 3 ( add 3 to both sides )

8 = 4a ( divide both sides by 4 )

a = 2

Thus

y = 2(x - 1)² - 3 ← in vertex form

Answer:

- 7, 0.9, 8.5, 16

Step-by-step explanation:

It should be that x must be greater than - 12, so let us consider all options;

[tex]- 20 < - 12,\\- 12 = - 12,\\ - 7 > 12,\\ 0.9 > 12,\\8.5 > - 12,\\16 > - 12[/tex]

Let us substitute x as each of these values;

[tex]x < - 12,\\x = - 12,\\x > - 12,\\x > - 12,\\x > - 12,\\x > - 12[/tex]

As you can tell, the last 4 Options are applicable;

Solution ⇒ - 7, 0.9, 8.5, 16

The solutions to inequality are - 7, 0.9, 8.5, and 16.

In mathematics, an inequality is a relation that makes a non-identical contrast between two numbers or other mathematical expressions.

Answer:

D

Step-by-step explanation:

A. The domain of this function is infinite, since x can be any number.

B. To find the y intercept, you need to set x to 0. 7^x will become 1, and 6*1=6, so the y intercept is (0,6).

C. This function is not always decreasing. For instance, when x is positive, it exponenentially increases.

D. As I said before, the y intercept of the function is (0,6), meaning that this statement is correct.

f(3) = 14

Step-by-step explanation:

Using the recursive formula and f(1) = 3 , then

f(2) = f(1) + 5.5 = 3 + 5.5 = 8.5

f(3) = f(2) + 5.5 = 8.5 + 5.5 = 14

[tex]\frac{x^2+4x-1}{x(x+2)}[/tex]

Step-by-step explanation:

Given

[tex]\frac{x+5}{x+2}[/tex] - [tex]\frac{x+1}{x^2+2x}[/tex] ← factor denominator

= [tex]\frac{x+5}{x+2}[/tex] - [tex]\frac{x+1}{x(x+2)}[/tex]

We require the fractions to have a common denominator.

Multiply numerator/denominator of first fraction by x

= [tex]\frac{x(x+5)}{x(x+2)}[/tex] - [tex]\frac{x+1}{x(x+2)}[/tex]

Subtract terms on numerator leaving the common denominator

= [tex]\frac{x^2+5x-x-1}{x(x+2)}[/tex]

= [tex]\frac{x^2+4x-1}{x(x+2)}[/tex]

Answer:

0.5

Step-by-step explanation:

Answer:

A = 25pi m^2

Step-by-step explanation:

We know the diameter, we need the radius

r = d/2

r = 10/2 = 5

The area of a circle is given by

A = pi r^2

A = pi (5)^2

A = 25pi m^2

Answer:

n=63

x=117

r=63

p=117

w=117

m=117

k=117

Step-by-step explanation:

If you start with the given angle of 63 p would  have to be 117 because 180-63 is 117. This would make r 63 because you would use the 117+63 to make a 180 degree angle. w will then be made 117 because it's vertical to p and vertical angles are congruent. we can find x by using corresponding angles. x= k because they are corresponding angles as well. n would be 63 because of k being 117 and because of vertical angles m is 117.

Answer:

  a) 50π cm^2

  b) π/8

Step-by-step explanation:

a) The formula for the area of a semicircle is ...

  A = (1/2)πr^2 = (1/2)π(d/2)^2 = (π/8)d^2

For a diameter of 20 cm, the area is ...

  A = (π/8)(20 cm)^2 = 50π cm^2 . . . . . the area of the semicircle

__

The formula for the area of a quarter circle is ...

  A = (1/4)πr^2

For a radius of 20 cm, the area is ...

  A = (π/4)(20 cm)^2 = 100π cm^2 . . . . . the area of the quarter circle

__

The shaded area is the difference of the areas of the quarter circle and semicircle:

  shaded area = (100π cm^2) -(50π cm^2)

  shaded area = 50π cm^2

__

b) The ratio of the shaded area to the square area is ...

  shaded area / square area = (50π cm^2)/(20 cm)^2 = π/8

Answer: 6 to 24

Step-by-step explanation:

Answer:

Let, height of the Building = x

Height of the Tower = y

Height of the tower is 5 times from height of the building = y = 5x

Height of the tower is 52 meter taller than the building = y-x = 52

put 5x instead of y in the equation y-x=52

5x-x=52

4x=52

x=52/4

x=13 meter

y=5x

y=5(13)

y=65 meter
