Step-by-step explanation:

Substitute k into the first equation

y=(3x)x, y=3x^2

Answer:

[tex]20.1\ \text{feet}[/tex]

Step-by-step explanation:

The given relation is

[tex]5x^2-2025=0[/tex]

where [tex]x[/tex] is the portion of walkway in which the person walks

Rearranging the equation we get

[tex]5x^2=2025\\\Rightarrow x^2=\dfrac{2025}{5}\\\Rightarrow x^2=405\\\Rightarrow x=\sqrt{405}\\\Rightarrow x=20.124\approx 20.1\ \text{feet}[/tex]

The length of the portion of the walkway labeled [tex]x[/tex] is [tex]20.1\ \text{feet}[/tex].

Answer:

15 rooms

Step-by-step explanation:

18/6 = 3 so multiply 3 times 5 and that equals 15!

Answer:

15 rooms.

Step-by-step explanation:

since they can clean 5 rooms in 6 hours, and it's asking how many rooms they can clean in 18 hours:

5/6=x/18

solve for x:

6x=90

x=15

Or you could've just multiplied 5 by 3 since 6(3)=18.

Answer:

x = 0

x = 2

x = -2

Step-by-step explanation:

f(x) = [tex]x^{3}[/tex] - 4x

Factor

f(x) = x ( [tex]x^{2}[/tex] - 4)

f(x) = x ( ( x - 2 ) ( x + 2 ) )

Answer:

a= 25.69, b=23.12, c=131.119

Step-by-step explanation:

[tex]cosa=\frac{B^{2} +C^{2} -A^{2} }{2BC} \\ =\frac{79.59}{88.32} \\ a = 25.69[/tex]

[tex]cos(b)=\frac{A^{2} +C^{2} -B^{2} }{2AC} \\ =\frac{89.69}{97.52}\\ b=23.12\\c=180-23.12-25.69\\ = 131.119[/tex]

Answer:

503.2 mi²

Step-by-step explanation:

The amount of impact could be obtained by finding the area of the Circumference ; which is the measure of the crater :

Circumference, C = 79.5

Area of circle = πr²

Radius, r :

From ; C = 2πr

79.5 = 2 * 3.14 * r

79.5 = 6.28r

r = 79.5 /6.28

r = 12.659235

Area of circle, A : πr²

A = 3.14 * 12.659235^2

A = 503.2045646656065

A = 503.2 mi²

Answer: 5390

Step-by-step explanation:

       7 0

×       7 7

+     4 9 0

+   4 9 0  

=  5 3 9 0

Answer:

I'm not going to do it for you but just offer the way I would do it.

1. Figure the overall area. Multiply the overall width by the overall length to get the overall area. If the overall length is not given, you'll have to add up from the numbers that are given.

2. Figure the area of each cutout. Again, length x width. Again, if they are not given, you'll have to do a little math with what you are given.

3. Subtract the area of each cutout from the overall area.

Answer:

n = 5

Step-by-step explanation:

Given

n + 16 = 21 ( isolate n by subtracting 16 from both sides )

n = 5

Answer:

n=5

Step-by-step explanation:

n+16=21

n=21-16

n=5

Answer:

x ≈ 13.5

Step-by-step explanation:

Using the sine rule in the triangle, then

[tex]\frac{sin34}{x}[/tex] = [tex]\frac{sin27}{11}[/tex] ( cross- multiply )

x × sin27° = 11 × sin34° ( divide both sides by sin27° )

x = [tex]\frac{11sin34}{sin27}[/tex] ≈ 13.5 ( to the nearest tenth )

Answer:

90 5/6

Step-by-step explanation:

Answer:

4 roots: 2 , -3, 1+√2, 1 - √2

Step-by-step explanation:

x⁴ − x³ − 9x² + 11x + 6 = 0    leading: 1 (x⁴)    Trailing: 6 (1,2,3,6)

possible roots: trailing/leading (±1 , ±2, ±3, ±6)

Test: x = 2     (2)⁴ - (2)³ - 9*(2)² + 11*(2) + 6 = 0

        x = -3    (-3)⁴ - (-3)³ - 9*(-3)² + 11*(-3) + 6 = 0

By rational roots test: possible roots (x-2)(x+3) are factors

Long division:  (x⁴ − x³ − 9x² + 11x + 6) / (x-2)(x+3) = x²-2x-1

roots of x²-2x-1: x= (-b±√b²-4ac) / 2a

x = (2 ± √4+4) / 2 = (2 ± 2√2) / 2 = 1 ± √2
