These triangles are similar. What is the value for it?

Answers

Answer 1

Answer:

Answer:

The vault of h is 10

Step-by-step explanation:

Since the whole triangle is 27 and the one side is 9 we know the other side must be 18. You multiply by 2 to get get from 9. That means they are similar and you just multiply 5 by 2 to get h=10.

3.Ms. Taylor is doing an art project with her class. She has a 3 foot piece of ribbon. If she gives each student an eighth of a foot of ribbon, how many students will receive a piece of ribbon

Answers

Answer:

Step-by-step explanation:

To solve this problem, first you would need to figure out how many eighths of a foot are in 3 foot. If the pieces she gave away were 1/8 of a foot, 8 pieces would be in 1 foot. Next, multiply 8 by the number of feet there are (3).

8 x 3 = 24

So, 24 students would receive a peice.

Use the product rule to calculate the derivatives of
( ax² + bx + c ) ( cx + d )

Answers

$\n \sf\longmapsto (d)/(dx)(ax^2+bx+c)(cx+d)$

$\boxed{\sf (d)/(dx)f(x).g(x)=f(x)(d)/(dx)g(x)+g(x)(d)/(dx)f(x)}$

c and d are constants

$\n \sf\longmapsto (ax^2+bx+c)(d)/(dx)(cx+d)+(cx+d)(d)/(dx)(ax^2+bx+c)$

$\n \sf\longmapsto (ax^2+bx+c)(c)+(cx+d)(2ax+b)$

$\n \sf\longmapsto acx^2+bcx+c^2+2acx^2+bcx+2adx+bd$

$\n \sf\longmapsto 3acx^2+2bcx+2adx+bd+c^2$

Answer:

• Product rule is as below:

${ \boxed{ \tt{ \: (dy)/(dx) = { \huge{v}} (du)/(dx) + { \huge{u}} (dv)/(dx) }}} \n$

u is (ax² + bx + c)
v is (cx + d)
du/dx is 2ax + bx
dv/dx is c

$\hookrightarrow \: { \rm{ (dy)/(dx) = (cx + d)(2ax + b) + (ax {}^(2) + bx + c)(c) }} \n \n { \rm{ (dy)/(dx) = (2ac {x}^(2) + bcx + 2adx + db) + (ac {x}^(2) + bcx + {c}^(2) )}} \n \n { \boxed{ \rm{ (dy)/(dx) = 3ac {x}^(2) + \{2bcx + 2adx \}x + (db + {c}^(2)) }}}$

A system of equations is shown. y = 3x - 2;. y = x^2. What are the solutions to the system of equations?

Answers

Answer:

(1,1) and (2,4) are the solutions to the system of equations.

Step-by-step explanation:

The two equations are:

$y=x^(2)$ ---------1

$y=3x-2$ ---------2

Putting value of y from equation 1 in equation 2 we get:

$x^(2)=3x-2\nx^(2)-3x+2=0\nFactorising\nx^(2)-x-2x+2=0\nx(x-1)-2(x-1)=0\n(x-1)(x-2)=0\nx=1,x=2$

When x=1 : $y=x^(2)=1$

When x=2 $y=x^(2) =4$

The solutions are (1,1) and (2,4).

Answer: the solutions to the system of equations are x = 2 and x = 1

Step-by-step explanation:

The system of equations given equation is

y = 3x - 2 - - - - - - - - - - 1

y = x^2 - - - - - - - - - - - - 2

Substituting 1 into equation 2, it becomes

x^2 = 3x - 2

x^2 - 3x + 2 = 0

We would apply the method of factorization in solving the equation. We will get two numbers such that when added, the result would be - 3x and when multiplied, the result would be 2x^2. The numbers are - 2x and - x. It becomes

x^2 - 2x - x + 2 = 0

x(x - 2) - 1(x - 2) = 0

(x - 2)(x - 1) = 0

x - 2 = 0 or x - 1 = 0

x = 2 or x = 1

use a calculator fo find the value

Answer:

a = 452.16 ft² area of walkway

a = -351.68 ft² area of the walkway minus the area of the fountain

Step-by-step explanation:

Area fountain

a = π16²

a = 256π

Area fountain and walkway

a = π(16 + 4)²

a = π20²

a = 400π

Area Walkway

a =400π - 256π

a = 144π

a = 144 * 3.14

a = 452.16 ft²

------------------------------

I think the Area of the Walkway is what the question should be asking for, but it asked for

"the area of the walkway minus the area of the fountain"

a = 144π - 256π

a = -112π

a = -112 * 3.14

a = -351.68
