Well you can't really solve it but it's false.

It's should be -8.8 < 2.3

> means "is greater than"

< means "is less than"

Answer:

The answer is below

Step-by-step explanation:

The distance between two points A(x₁, y₁) and B(x₂, y₂) on the coordinate is:

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\[/tex]

An equilateral triangle is a triangle with three equal sides (all sides are equal).

a) Given vertices at A(-2,2), B(1,5), and C(-3,6):

[tex]AC=\sqrt{(-3-(-2))^2+(6-2)^2}=\sqrt{1+16}=\sqrt{17}=4.12\ unit\\\\AB=BC=AC=4.12\ unit[/tex]

b) Perimeter = AB + BC + AC = 3 * AC = 3 * 4.12 = 12.36 unit

c) If the scale factor is increased by 4, all the sides would also increase by 4. Hence the new length would be:

A'B' = B'C' = A'C' = 4 * AC = 4 * 4.12 = 16.48 unit

d) Perimeter = A'B' + B'C' + A'C' = 3 * A'C' = 3 * 16.48 = 49.44 unit

e) Area = [tex]\frac{\sqrt{3} }{4}*AC^2=\frac{\sqrt{3} }{4} *4.12^2=7.35\ unit^2[/tex]

Answer:

A. 2x - (4x + 3) = 12

Step-by-step explanation:

A. 2x - (4x + 3) = 12

B. -4(4y+)+y=3

C. 2 (4x+3) - y

D. -4x+4 x-3=3

Given equation:

-4x+y = 3. (1)

2x - y = 12. (2)

From (1)

y = 3 + 4x

Substitute y = 3 + 4x into (2)

2x - y = 12 (2)

2x - (3 + 4x) = 12

Or

2x - (4x + 3) = 12

2x - 4x - 3 = 12

- 2x = 12 + 3

- 2x = 15

x = 15/-2

x = -7.5

Substitute x = -7.5 into (1)

-4x+y = 3 (1)

-4(-7.5) + y = 3

30 + y = 3

y = 3 - 30

y = -27

Height = 6000 m

Step-by-step explanation:

[tex]Volume = length \times breadth \times height \\\\480000 = 10 \times 8 \times height\\\\480000 = 80 \times height\\\\height = \frac{480000}{80} = 6000 \ m[/tex]

Answer:

x=1

Step-by-step explanation:

4x-10+1.5x-4x+11=8.5-6

Combine like terms

1.5x+1=2.5

Subtract 1 from each side

1.5x+1-1=2.5-1

1.5x = 1.5

Divide by 1.5

1.5x/1.5 = 1.5/1.5

x=1

Answer:

x=1

Step-by-step explanation:

Given :

4x-10+1.5x-4x+11=8.5-6

4x+1.5x-4x=8.5-6-11+10

1.5x=1.5

x=1

Value of x=1

Answer:

The answer is 11.8 m

Step-by-step explanation:

Hey Mate,

the volume of a cuboid is = whl....so the volume of it is the capacity of the tank

so 3 x 1.8 x 2.2 = 11.88 m is the answer

Answer:

160°

Step-by-step explanation:

since it is a parallelogram it's opposite angles must be equal . So,

angle GHE = angle EFG

160 degree = angle EFG

Answer:

find X in X with x if you find X with x in with x you got a formula

Part (A)

(1 cm)/(20 cm) = (6 cm)/(x cm)

1/20 = 6/x

1*x = 20*6

x = 120

120 cm = 120/100 = 1.2 m

=========================================================

Part (B)

2.2 m = 2.2*100 = 220 cm

(1 cm)/(20 cm) = (x cm)/(220 cm)

1/20 = x/220

1*220 = 20*x

20x = 220

x = 220/20

x = 11

Answer:

a. 26 cm²

b. 55 cm²

c. 78 cm²

d. 89.27 cm²

Step-by-step explanation:

a. The shape can be decomposed into two rectangles

Area of the larger rectangle = L*W

L = 7 cm

W = 2 cm

Area of the larger rectangle = 7*2 = 14 cm²

Area of the smaller rectangle = L*W

L = 4 cm

W = 5 - 2 = 3 cm

Area of the larger rectangle = 4*3 = 12 cm²

Area of the compound shape = 14 + 12 = 26 cm²

b. The shape can be decomposed into a rectangle and a triangle.

Area of the compound shape = area of rectangle + area of triangle

= L*W + ½*b*h

L = 8 cm

W = 5 cm

b = 5 cm

h = 14 - 8 = 6 cm

Plug in the values

Area = 8*5 + ½*5*6

Area = 40 + 15

= 55 cm²

c. The shape can be decomposed into a rectangle and a trapezoid

Area of the compound shape = area of the rectangle + area of the trapezoid

= L*W + ½(a + b)h

L = 12 cm

W = 3 cm

a = 12 cm

b = 9 cm

h = 4 cm

Plug in the values

Area = 12*3 + ½(12 + 9)4

Area = 36 + 42

Area = 78 cm²

d. The shape can be decomposed into a rectangle and a semicircle

Area of the compound shape = area of the rectangle + area of the semicircle

= L*W + ½(πr²)

L = 10 cm

W = 5 cm

r = ½(10) = 5 cm

Plug in the values

Area = 10*5 + ½(π*5²)

Area = 50 + 39.27

Area = 89.27 cm²

Step-by-step explanation:

y=2*(3+x)  

y=3x-2

3x-y=2

Answer:

Answer is y = 6

Step-by-step explanation:

Solve for y.

Answer:

Y=6 I think but I’m not positive.

sorry if I’m wrong.

haha

get it? POSITIVE?

Answer:

minimum value of 6

Step-by-step explanation:

Given

y = x² - 10x + 31

with a = 1, b = - 10

Since a > 0 then the function has a minimum value

The minimum value is the y- coordinate of the vertex.

The x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex] = - [tex]\frac{-10}{2}[/tex] = 5

Substitute x = 5 into the function for y- coordinate of vertex

y = 5² - 10(5) + 31 = 25 - 50 + 31 = 6

The function has a minimum value of 6

Answer:

none

Step-by-step explanation:

any value on y cancel 4y and then we will have -12=12 which is not true.

Answer:

Step-by-step explanation:

6,7,8

Answer:

Where 0 < x < 3

The location of the local minimum, is (2, 0)

The location of the local maximum is at (0, 16)

Step-by-step explanation:

The given function is f(x) = (x + 2)⁴

The range of the minimum = 0 < x < 3

At a local minimum/maximum values, we have;

[tex]f'(x) = \dfrac{(-x + 2)^4}{dx} = -4 \cdot (-x + 2)^3 = 0[/tex]

∴ (-x + 2)³ = 0

x = 2

[tex]f''(x) = \dfrac{ -4 \cdot (-x + 2)^3}{dx} = -12 \cdot (-x + 2)^2[/tex]

When x = 2, f''(2) = -12×(-2 + 2)² = 0 which gives a local minimum at x = 2

We have, f(2) = (-2 + 2)⁴ = 0

The location of the local minimum, is (2, 0)

Given that the minimum of the function is at x = 2, and the function is (-x + 2)⁴, the absolute local maximum will be at the maximum value of (-x + 2) for 0 < x < 3

When x = 0, -x + 2 = 0 + 2 = 2

Similarly, we have;

-x + 2 = 1, when x = 1

-x + 2 = 0, when x = 2

-x + 2 = -1, when x = 3

Therefore, the maximum value of -x + 2, is at x = 0 and the maximum value of the function where 0 < x < 3, is (0 + 2)⁴ = 16

The location of the local maximum is at (0, 16).

Answer:

future value = $8700(1.091)^x

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r) n

FV = Future value  

P = Present value = 8700

R = interest rate = 9.1%

N = number of years  = x

future value = $8700(1.091)^x

Q. Determine if the rates are equilvalent. Explain your reasoning. 25 hours in 5 days; 8 hours in 2 days. . .

[tex] \dashrightarrow [/tex] No!, as, we have 25 hours in 5 dyas is the equals to 5. While, 8 hours in 2 days is equals to 4.

Here, is a difference of 1 in 5 and 4.

Answer:

30°

Hope this answer is right!

Step-by-step explanation:

to go around the shape, you make a complete circle: 360°. So, divide 360° by the dodecagon's twelve exterior angles. Each exterior angle is 30°.

Step-by-step explanation:

1. length ×breadth ×height

12× 6 ×3= 216

2. A is the area of the base, h is the height

18×16=288

3.10×14×5=700

Answer:

21. 216m^3

22. 4071.5m^3

23. 700m^3

Step-by-step explanation:

21. V =  L*W*H

V = 3*6*12

V = 216

22. V = [tex]\pi r^{2} h[/tex]

The diameter is 18 so the radius is 9

V = [tex]\pi[/tex](9^2)(16)

V= 4071.50408

23.  V =  L*W*H

V= 10*5*14

V=700

From the graph it seems to be around the area of 10%.

So,

18,000 * 0.10 = $1,800

Answer: [tex]P=795(1.84)^n[/tex]

Step-by-step explanation:

Given

Initial population was [tex]795[/tex] people

By 2020, it becomes [tex]1262[/tex] people

Suppose the population follows the trend [tex]P=P_oa^{n}[/tex]

where, [tex]n[/tex] is the number of years after 2014

For year 2020 it is 6. Insert the values

[tex]\Rightarrow 1262=795a^{6}\\\\\Rightarrow 1.587=a^{6}\\\\\text{Taking log both sides}\\\\\Rightarrow \log (1.587)=6\log (a)\\\Rightarrow \log (a)=0.2645\\\\\Rightarrow a=10^{0.2645}\\\Rightarrow a=1.84[/tex]

Thus, the exponential population trend is [tex]P=795(1.84)^n[/tex]
