Answer: B. Yes, Because 3^2 + 4^2 = 5^2

Step-by-step explanation:

ONLY FOR RIGHT TRIANGLES

the biggest side is square root of the sum of the smaller sides squared(a^2 + b^2 = c^2)

So:

3^2 + 4^2 = 5^2

9 + 16 = 25

25 = 25

B. Yes, Because 3^2 + 4^2 = 5^2

¿Cuál de las siguientes funciones es una función constante? Seleccione una: a. Y=x+1 b. Y=x+2 c. X=y+3 d. Y=3

JulijaS [17]

Answer:

Option D y=3

Step-by-step explanation:

The question in English is

Which of the following functions is a constant function?

we know that

A <u>constant function</u> is a function whose output value is the same for every input value

<u><em>Verify each case</em></u>

case A) y=x+1

This is not a constant function, this is a linear equation

Is a function whose output value is different for every input value

case B) y=x+2

This is not a constant function, this is a linear equation

Is a function whose output value is different for every input value

case C) x=y+3

This is not a constant function, this is a linear equation

Is a function whose output value is different for every input value

case D) y=3

This is a constant function

Is a function whose output value is the same for every input value

What do you get when you distribute -1 to the (9x-6)

DENIUS [597]

Answer:

-9x +6

Step-by-step explanation:

The usual statement of the distributive property tells you how this works:

a(b + c) = ab + ac

-1(9x -6) = (-1)(9x) +(-1)(-6) = -9x +6

Distance between (-4, 6) and (3, 7)

sweet-ann [11.9K]

Answer: $5\sqrt{2}$

Step-by-step explanation:

$Distance\ formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} }$

plugging in the values we know:

$x_2 = 3,\ x_1=-4,\ y_2=7,\ y_1=6$

Therefore,

$Distance=\sqrt{(3-(-4))^2+(7-6)^2}$

$\rightarrow\ \sqrt{(3+4)^2+(1)^2}$

$\rightarrow\ \sqrt{7^2+1}$

$\rightarrow\ \sqrt{50}$

$\rightarrow\ \sqrt{5\times5\times2}$

$\rightarrow\ \large\boxed{5\sqrt{2}}$

How many boys are there in an introductory chinese course if 363 students are enrolled and there are six boys to every five girl

loris [4]

There are 198 boys in the introductory Chinese course

<h3>How to determine the number of boys?</h3>

The given parameters are

Total = 363

Ratio = Boys : Girls = 6 : 5

So, we have

Boys =6/(5 + 6) * total number of students

This gives

Boys = 6/11 * 363

Evaluate

Boys = 198

Hence, there are 198 boys in the introductory Chinese course

An alloy consists of nickel, zinc, and copper in the ratio 2:7:9.

Alexus [3.1K]

Answer:

0.4kg, 1.4kg and 1.8kg

Step-by-step explanation:

Given parameters:

Mass of alloy = 3.6kg

Ratio of elements in the alloy = 2:7:9

Unknown:

Mass of each element in the alloy = ?

Solution:

To find the mass of each element in the alloy, first find the sum of the ratio;

2+7+9 = 18

Mass of nickel = $\frac{2}{18}$ x 3.6 = 0.4kg

Mass of zinc = $\frac{7}{18}$ x 3.6 = 1.4kg

Mass of copper = $\frac{9}{18}$ x 3.6 = 1.8kg

The mass of each metal is 0.4kg, 1.4kg and 1.8kg
