What are similar triangles?

When two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.

Given that, Δ ABC ~ Δ DEF

The proportion = AB/DE = BC/EF = AC/DF = 5/3

2/EF = 5/3

EF = 6/5

5/DF = 5/3

DF = 3

Hence, The values of DF and EF are 3 and 6/5 respectively. (option A)

what is the formula to calculate velocity?

Answers

Answer:

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.

4y -9x =-23 x=y-3 what is the y-value

Answers

Answer:

y = 10

Step-by-step explanation:

Use the substitution method since you already know what x equals.

4y - 9(y - 3) = -23

Simplify:

4y - 9y + 27 = -23

Combine like terms:

-5y + 27 = -23

Isolate y by subracting 27 from both sides:

-5y = -50

Divide by -5 to get y by itself:

-5/-5 = y

-50/-5 = 10

Hi there!

Since the dot is in the fourth quadrant, our x value will have to be positive. If the value was negative, it would be in the third quadrant.

If you think about the dot’s relation to the y axis, it is below the point of origin, or y = 0, so the y-value will have to be negative.

The only answer that fits this criteria is (3,-5)

The value of computer decreases with its age until it is worth nothing a computer that was purchases new for 0 years is worth 2220 1540 after 6 years problem whats the value after 8 years and what is the linear function V(x)

Answers

Answer:

[tex]V(x) = -\frac{340}{3}x +2220[/tex]

[tex]V(8) = 1313.3[/tex]

Step-by-step explanation:

Given

Let x represent years and V represents the value.

So, we have:

[tex](x_1,v_1) = (0,2220)[/tex]

[tex](x_2,v_2) = (6,1540)[/tex]

Solving (a): The linear function

First, we calculate the slope (m)

[tex]m = \frac{v_2 - v_1}{x_2 - x_1}[/tex]

This gives:

[tex]m = \frac{1540-2220}{6-0}[/tex]

[tex]m = \frac{-680}{6}[/tex]

[tex]m = -\frac{340}{3}[/tex]

The linear function is calculated using:

[tex]v - v_2 = m(x - x_2)[/tex]

Where:

[tex](x_2,v_2) = (6,1540)[/tex]

[tex]m = -\frac{340}{3}[/tex]

So, we have:

[tex]v - 1540 = -\frac{340}{3}(x - 6)[/tex]

Open bracket

[tex]v - 1540 = -\frac{340}{3}x +\frac{340}{3}* 6[/tex]

[tex]v - 1540 = -\frac{340}{3}x +680[/tex]

Make v the subject

[tex]v = -\frac{340}{3}x +680+1540[/tex]

[tex]v = -\frac{340}{3}x +2220[/tex]

So, the function is:

[tex]V(x) = -\frac{340}{3}x +2220[/tex]

Solving (b): When x = 8

Substitute 8 for x in [tex]V(x) = -\frac{340}{3}x +2220[/tex]

[tex]V(8) = -\frac{340}{3}*8 +2220[/tex]

[tex]V(8) = -\frac{340*8}{3} +2220[/tex]

[tex]V(8) = -\frac{2720}{3} +2220[/tex]

Take LCM

[tex]V(8) = \frac{-2720+2220*3}{3}[/tex]

[tex]V(8) = \frac{-2720+6660}{3}[/tex]

[tex]V(8) = \frac{3940}{3}[/tex]

[tex]V(8) = 1313.3[/tex]

Hence, its value after 8 years is 1313.3

Answer:

The inequality describes all possible value of x is 14 < x < 32D

Step-by-step explanation:

In any triangle:

The sum of the lengths of any two sides must be greater than the length of the 3rd sideThe length of any side must greater than the difference of the lengths of the other two sidesThe difference of the other sides < The side < The sum of the other sides

In the given figure

ABC is a triangle

∵ AC = 9 and BC = 21

∵ AB is the third side of the triangle

→ By using the rules above

BC - AC < AB < BC + AC

∵ AB = x - 2

→ Substitute their values in the inequality above

21 - 9 < x - 2 < 21 + 9

∴ 12 < x - 2 < 30

→ Add 2 to the 3 terms

∴ 12 + 2 < x - 2 + 2 < 30 + 2

14 < x < 32

The inequality describes all possible value of x is 14 < x < 32
