Answer: 38

Step-by-step explanation: to evaluate an expression for these variables, plug in those numbers for the variables.

Plugging in -1 for y and -19 for z gets you this:

-2(-1)^2(-19)

Now simplify according to order of operations (PEMDAS - parenthesis exponents multiplication/division addition/subtraction)

-1^2 = 1

-2(1) = -2

-2(-19) = 38

Your answer is 38

Answer:

sin q = 14/50

cos q = 24/25

tan q = 7/24

sin r = 24/25

cos r = 7/25

tan r = 24/7

Step-by-step explanation:

The required trigonometric ratio are as follows;

[tex]SinR= \frac{24}{25}, CosR = \frac{7}{25}, TanR = \frac{24}{7} \\\\SinQ = \frac{7}{25}, CosQ = \frac{24}{25}, TanQ = \frac{7}{24}[/tex]

WE have to determine the trigonometric function in simplest form.

In order to find trigonometric ratio, In right angle triangle QRP.

Length of PR = 14

Length of QR = 50

To find length of PQ using Pythagoras theorem.

[tex](H)^{2} = (P)^{2} + (B)^{2}\\\\(50)^{2} = (14)^{2} + (B)^{2} \\\\B^{2} = 2500 - 196\\\\B^{2} = 2304\\\\B = 48[/tex]

Length of PQ is 48.

Therefore,

Sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse)

Then,

[tex]SinQ = \frac{perpendicular}{hypotenuse} \\\\SinQ = \frac{14}{50}\\\\SinQ = \frac{7}{25}[/tex]

The ratio of the length of the side adjacent to the angle to the length of the hypotenuse.

[tex]CosQ = \frac{Base}{hyptotenuse}\\\\CosQ = \frac{48}{50} \\\\CosQ = \frac{24}{25}[/tex]

The tangent of an angle is the length of the opposite side divided by the length of the adjacent side.

[tex]TanQ = \frac{perpendicular}{Base}\\\\TanQ = \frac{14}{48} \\\\TanQ = \frac{7}{24}[/tex]

And In right angle triangle RPQ,

Sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse).

[tex]SinQ = \frac{perpendicular}{hypotenuse} \\\\SinQ = \frac{48}{50}\\\\SinQ = \frac{24}{25}[/tex]

The ratio of the length of the side adjacent to the angle to the length of the hypotenuse.

[tex]CosQ = \frac{Base}{hyptotenuse}\\\\CosQ = \frac{14}{50} \\\\CosQ = \frac{7}{25}[/tex]

The tangent of an angle is the length of the opposite side divided by the length of the adjacent side.

[tex]TanQ = \frac{perpendicular}{Base}\\\\TanQ = \frac{48}{14} \\\\TanQ = \frac{24}{7}[/tex]

Answer:

176

Step-by-step explanation:

First term (a) = 29

Common difference (d) = 32 - 29 = 3

For calculating the 50th term , n = 50

Now

[tex]t_{50} = a + ( n - 1) d\\t_{50} = 29 + ( 50 - 1 ) *3\\ t_{50} = 29 + 147\\t_{50} = 176[/tex]

Answer:

x = 2/3

Step-by-step explanation:

Let's unpack the equation [tex]x*2=5[/tex] from our definition of [tex]*[/tex]:

[tex]x*2=3x+2(2)-1=5[/tex] (where [tex]x\in \mathbb{Z}[/tex])

Now that we've got things defined in terms of familiar operations, we can simplify and solve for x:

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

Answer:

x=5

Step-by-step explanation:

add 5 to both sides

-20+5 = -3x

-15=-3x   (divide)

Answer:

viii. 2x(1 - 2x)(1 + 2x)(1 + 4x²)

ix. 4xy

Step-by-step explanation:

viii. 2x - 32x⁵

= 2x(1 - 16x⁴)

= 2x(1² - (4x²)²)

= 2x(1 + 4x²)(1 - 4x²) ( a² - b² = (a + b)(a - b))

= 2x(1 + 4x²)(1² - (2x)²)

= 2x(1 + 4x²)(1 - 2x)(1 + 2x)

ix. (x+y)² - (x - y)²

= (x+ y + x - y)( x + y - x + y)

= 2x x 2y

= 4xy

Answer:

Step-by-step explanation:

First, let's find x:-

(15x-2)° = (9x+10)°

15x-2 = 9x+10

6x = 12

x = 2°

Now, let's find y:-

28 + y° = 180°

y = 180-28

y = 150°

Answer:

4.1

Step-by-step explanation:

61.50/15 = 4.1

per liter= AED 4.1

Answer:

Step-by-step explanation:

Assuming that your figure is a triangle, we should keep in mind that all the interior angles of a triangle add up to 180°, always.

So, we have the values of angles x and y as 90° and 64°.

90 + 64 = 154°  ⇒ Add them up.

Now, subtract 154 from 180 to get ∠z.

180 - 154 = 26°

Answer:

[tex]\Large \boxed{\sf 384 \ m^2}[/tex]

Step-by-step explanation:

Surface area ⇒ area of 2 triangles + area of 3 rectangles

[tex](8 \times 3 \times 0.5 \times 2)+(20 \times 5 \times 2+20 \times 8)=384[/tex]

For a prism we take into account the following:

Taking into account the above, we first find the lateral area:

In the triangular base, the height divided into 2 small right triangles of Hypotenuse = 5 and Height = 3. By Pythagoras we have this:

9 + base² = 25

base² = 25 - 9

base² = 16

base = 4

From this we obtain that the bases of the small right triangles measure 4 therefore the triangular base is isosceles where we have:

The perimeter of the triangular base will be the sum of the sides, that is:

Perimeter = 5 + 5 + 8

⇒ Perimeter = 18

Since the perimeter of the base of the prism is 18 and the height is 20, we replace in the equation for the lateral area:

Side area = (18) (20)

⇒ Lateral Area = 360 m²

Now we find the area of ​​the triangular base with base = 8 and height = 3:

[tex]\bold{Area=\dfrac{(base) (height)}{2} }\\\\\\Area=\dfrac{(8)(3)}{2} \\\\\\Area=\dfrac{24}{2}\\\\\\\boxed{\bold{Area=12}}[/tex]

Since we have that the lateral area is 360m² and the area of ​​the triangular base is 12m², we replace in the equation of the total area:

Total area = 360 + 2 (12)

Total area = 360 + 24

Total area = 384 m²

The total area of ​​the prism will measure 384m²
