Halo!!! i wrote my answer below your epic btw

Step-by-step explanation:

you first have to break up the surface of the shape into smaller shapes so that they are easier to work with. you then calculate all of the shapes and add them together. this can be used in the real world to find the area of houses when you need to find how much space an area of the house has.

PS:If u didnt learn to find surface area this way insert anything you want into the beggining sorry i dont know what youve been learning

Answer:

y = 0.1(x + 5)² + 1.5

Step-by-step explanation:

Equation of a parabola having vertex at (h, k) is given by,

y = a(x - h)² + k

From the given graph, vertex of the parabola is (-5, 1.5)

Therefore, equation of the parabola will be,

y = a(x + 5)² + 1.5

Since, this parabola passes through a point (0, 4)

4 = a(0 + 5)² + 1.5

4 = 25a + 1.5

25a = 2.5

a = 0.1

By substituting the value of 'a' in the equation of the parabola,

y = 0.1(x + 5)² + 1.5

Answer:

a - 129

b - 63

Step-by-step explanation:

for a - supplementary angles add up to equal 180

so to find the measure of its supplement we subtract the given angle from 180 180-51=129

so the measure of a supplement angle is 129

for b - complementary angle add up to equal 90

so to finds the measure of its complement we subtract the given angle from 90

90-27=63

so the measure of its complement is 63

Answer:

(a) An angle measures 51°. the measure of its supplement=180-51=129°

b) An angle measures 27°. the measure of its complement=90-27=63°

Step-by-step explanation:

subtract 5 under itself and 21 , then cross out the 5 and only subtract 21 and 5 which is 16 and then bring down 2x so now your equation will be 2x=5 so now your gonna divide 2 and 5

Answer:

The height is 14.3 km

Step-by-step explanation:

Given

[tex]distance= 12km[/tex]

[tex]\theta= 50[/tex] --- angle of elevation

Required

Determine the height above the ground

The question is illustrated using the attached image.

To calculate the required height, we make use of:

[tex]tan(\theta) = \frac{AB}{BC}[/tex]

Where AB represents the height and BC, the distance.

So:

[tex]tan(50) = \frac{AB}{12}[/tex]

Make AB the subject

[tex]AB = 12 * tan(50)[/tex]

[tex]AB = 12 * 1.1918[/tex]

[tex]AB = 14.3016[/tex]

[tex]AB = 14.3km[/tex] --- approximated

The height of the airplane above the ground is 9.19 km.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let h represent the height of the airplane above the ground. Hence:

sin(50) = h / 12

h = 9.19 km

The height of the airplane above the ground is 9.19 km.

Answer:  x=3

Step-by-step explanation; Add 5 to both sides of the equation

6x-5+5=2x+7+5

simplify: add the numbers

6x-5+5=2x+75 = 6x=2x + 7+5

6x =2x + 7+5

6x=2x +12.

subtract 2x from both ides of the equation: 6x=2x + 12

6x - 2x =2x + 12-2x6

combine like terms  u should get 4x= 12

divided both sides of the equation by the same term 4x=12  4x/4 =12/4

Cancel terms that are in both the numerator and denominator u should get  x=12/4

divided the numbers and ur answer is X=3

Answer:

78.54 m^2

Step-by-step explanation:

The computation of the area of the circle is shown below:

As we know that

Area of the circle = πr^2

Also

Diameter = 2r

10 = 2r

r = 5

So, the area of the circle is

=  3.14 × 5^2

= 78.54 m^2

Answer:

the Value of y=3 and x=5or 4.5

Answer:

0.0143 = 1.43% probability that first 4 digits of the code are even numbers.

Step-by-step explanation:

Arrangements of n elements:

The number of possible arrangements of n elements is given by:

[tex]A_{n} = n![/tex]

Probability:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

Desired outcomes:

First four digits are even(2, 4, 6 and 8 are even, so arrangements of 4 elements).

Last four digits are odd(1, 3, 5 and 7 are odd, so the last four elements are also arrangements of 4 elements). So

[tex]D = 4!*4! = 24*24 = 576[/tex]

Total outcomes:

Arrangements of 8 digits. So

[tex]T = A_{8} = 8! = 40320[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{576}{40320} = 0.0143[/tex]

0.0143 = 1.43% probability that first 4 digits of the code are even numbers.

The new width is 5.6 in

Step-by-step explanation:

Given

New

[tex]H_2 = 22.4[/tex]

Old

[tex]H_1 = 5.6[/tex]

[tex]W_1 = 1.4[/tex]

Required

The new width

This is calculated using the following equivalent ratio

[tex]H_2 : W_2 = H_1 : W_1[/tex]

[tex]22.4 : W_2 = 5.6 : 1.4[/tex]

Express as fraction

[tex]W_2/22.4 = 1.4/5.6[/tex]

Multiply both sides by 22.4

[tex]W_2= 1.4/5.6 * 22.4[/tex]

[tex]W_2= 5.6[/tex]

Answer:

  (x, y) → (-∞, -∞), (+∞, +∞)

Step-by-step explanation:

The expression is of odd degree with a positive leading coefficient. It will have a generally upward slope (/). That is, the sign of f(x) will match the sign of x for large-magnitude values of x:

  x → -∞, f(x) → -∞

  x → ∞, f(x) → ∞
