Find the missing sides from the right-angled triangles given below. Step by step

Answers

Answer 1

Answer:

BD = √13cm, AC = 10c,

Step-by-step explanation:

[tex]AB^2 = AD^2 + BD^2\\\\49 = 36 + BD^2\\\\BD = \sqrt{49 - 36} = \sqrt{13}cm\\\\AC^2 = AD^2 +DC^2\\[/tex]

[tex]=36 + 64\\=100[/tex]

[tex]\\AC = \sqrt{100} = 10cm[/tex]

Answer 2

BD=£ 13cm, AC=10c,

Which function has a graph with a vertical
asymptote at x = 7 and a horizontal asymptote at
f(x) = -3?
Please help me

Answers

Answer:

[tex]f(x)=\frac{1}{x-7}-3[/tex], see the graph attached for a visual reference.

Step-by-step explanation:

Vertical asymptotes are only present in rational functions where the parent function [tex]f(x)=\frac{1}{x}[/tex] has a vertical asymptote at the line [tex]x=0[/tex] and a horizontal asymptote at the line [tex]y=0[/tex]. Because the vertical asymptote has to be [tex]x=7[/tex], the denominator must be x-7 in order for the denominator to equal 0. For the horizontal asymptote to be [tex]y=-3[/tex], then 3 must be subtracted from the rational function. Therefore, the function that has these asymptotes is [tex]f(x)=\frac{1}{x-7}-3[/tex].

f(x) = 3 / (-3x - 3)

To find the vertical asymptotes, set the denominator of f(x) equal to zero.

-3x - 3 = 0

-3x = 3
x = -1

The vertical asymptote is
x = -1

To find the horizontal asymptotes, we examine the degree of the numerator and denominator of f(x). We use the leading terms to determine the degree. The leading term in the numerator is 7x0. The leading term of the denominator is -3x1. Since the exponent of x in the numerator is 0, the degree is 0 . Since the exponent of x in the denominator is 1, the degree is 1. The degree in the numerator is less than the degree in the denominator. Therefore, the horizontal asymptote is

y = 0

This also indicates that there are no x-intercepts.

To find the y-intercepts, set x=0.

The y-intercept is (0, -7/3).

Solve for the given variable.
a. 4y + 3 = 19

b. 1
2n - 3 = 5

Answers

Answer:

y=4

Step-by-step explanation:

4y+3=19

=4y=19-3

=y=16/4=4

Answer:

a) y = 4

b) n = 4

Step-by-step explanation:

a) 4y + 3 = 19

Subtract 3 from both sides.

4y = 16

Divide both sides by 4.

y = 4

b) Is the 1 apart of the equation? If not, these are the steps to find n.

2n - 3 = 5

Add 3 to both sides.

2n = 8

Divide both sides by 2.

n = 4

To build a pizza, customers choose stuffed (S) or thin (T) crust, red (R) or white (W) sauce, and a topping. The choices for toppings are pepperoni (P), sausage (S), or vegetables (V).

The following list shows the possible pizzas that can be made. The first letter represents the crust, the second letter represents the sauce, and the third letter represents the topping. For example, a stuffed-crust pizza with red sauce and pepperoni is listed as SRP, and a stuffed-crust pizza with white sauce and sausage is listed as SWS.

Which graph represents the solution of 3y-9≤6x?

Answers

A is correct when you do this B looks close but it’s A

The graph that represents the solution of 3y - 9 ≤ 6x is option A.

Option A is the correct answer.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

3y - 9 = 6x

We can find the following coordinates.

When x = 0,

3y - 9 = 0

3y 9

y = 3

When y = 0,

3y - 9 = 6x

-9 = 6x

x = -9/6

x = -3/2

x = -1.5

Thus,

The graph on option A represents the solution.

Explain how to decompose a triangle into congruent triangles. How does the area of those decomposed triangles relate to the area of the rectangle?

Answers

So for any triangle, you can divide it into four congruent triangles by connecting the midpoints of each side. You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole.
