What is the area of this figure?

Answers

9514 1404 393

Answer:

  288 cm²

Step-by-step explanation:

The figure decomposes into two rectangles and a triangle.

It is helpful to realize the overall horizontal length of the figure is 16+10+6 = 32 cm. That means the triangle at lower left has a width of 32-13 = 19 cm. Of course the bottom rectangle has a width of 10+6 = 16 cm.

The upper rectangle has an area of ...

  A = LW = (6 cm)(4 cm) = 24 cm²

The lower rectangle has an area of ...

  A = LW = (16 cm)(7 cm) = 112 cm²

The triangle has an area of ...

  A = 1/2bh = 1/2(19 cm)(16 cm) = 152 cm²

__

Then the total area of the figure is ...

  24 cm² +112 cm² +152 cm² = 288 cm²

Answer:

Reason 2)The transitive property of congruence

Step-by-step explanation:

There are several sort of "obvious" properties of equality/congruence. Keeping them sorted out can be a bit of a trick.

  A = A . . . . reflexive property

  A = B ⇔ B = A . . . . symmetric property (erroneously cited in the proof)

  A = B, B = C ⇒ A = C . . . . transitive property (the one needed in the proof)

__

Not to confuse the issue, but there is also the "substitution property of equality" that says if X = Y, then X can be substituted for Y or vice versa. In the end, the transitive property is an application of this, where we're substituting for B in the second equation, or for A in the first equation.

The A=B=C form of Statement 1) in the proof is what gives you the clue it is the transitive property that is wanted here.

State of the given functions are inverses

Answers

Answer:

1) They are not inverses

2) They are inverses

Step-by-step explanation:

We need to find the composition function between these functions to verify if these functions are inverses. If f[g(x)] and g[f(x)] are equal to x they are inverses.

1)

Let's find f[g(x)] and simplify.

[tex]f[g(x)]=\frac{1}{2}g(x)+\frac{3}{2}[/tex]

[tex]f[g(x)]=\frac{1}{2}(4-\frac{3}{2}x)+\frac{3}{2}[/tex]    

[tex]f[g(x)]=\frac{7}{2}-\frac{3}{4}x[/tex]

As f[g(x)] is not equal to x, these functions are not inverses.

2)

Let's find f[g(x)] and simplify.

[tex]f[g(n)]=\frac{-16+(4n+16)}{4}[/tex]

[tex]f[g(n)]=\frac{-16+4n+16}{4}[/tex]

[tex]f[g(n)]=\frac{4n}{4}[/tex]

[tex]f[g(n)]=n[/tex]

Now, we need to find the other composition function g[f(x)]

Let's find g[f(x)] and simplify.

[tex]g[f(x)]=4(\frac{-16+n}{4})+16[/tex]

[tex]g[f(x)]=-16+n+16[/tex]

[tex]g[f(x)]=n[/tex]

Therefore, as f[g(n)] = g[f(n)] = n, both functions are inverses.

  B) 25 m; 200 m/s

  C) (20.41, 2065.82)

Step-by-step explanation:

When you are first introduced to equations for ballistic motion, you may be told that the formula is ...

  h(t) = -4.9t² +v₀t +h₀ . . . . . height in meters at time t seconds

where v₀ is the initial upward velocity in meters per second, and h₀ is the initial height in meters.

When you are first introduced to quadratic equations, and the vertex form in particular, you may be told that the form is ...

  f(x) = a(x -h)² +k . . . . . . . vertex (h, k) and vertical scale factor 'a'

When the scale factor (or leading coefficient) is negative the graph of the parabola opens downward. When it is positive, the graph opens upward.

Knowing these things, you are prepared to match the given equation to these patterns.

__

Part A: We observe that the leading coefficient of the function (-4.9) is negative, so the parabola opens down.

__

Part B: The constant in the first given equation is 25, so the initial height is 25 meters.

The coefficient of t in the first given equation is 200, so the initial velocity of the rocket is 200 m/s.

__

Part C: The vertex can be read from the second equation as ...

  (h, k) = (20.41, 2065.82)

Step-by-step explanation:

For every 5 people employed in sales, there are 14 employed in marketing.

This means that:

5/(5+14) = 5/19 of people work in sales.

14/(5+14) = 14/19 of people work in marketing.

Total of 209 people:

14*209/19 = 154

154 people work in marketing.

5*209/19 = 55

You borrowed 43,800 at a SIMPLE interest rate of 4.8%. If you pay it back in 2 years, how much
Interest is paid pack?

Answers

Answer:

I = $4204.8

Step-by-step explanation:

Given that,

Principal, P = $43,800

Interest rate = 4.8%

Rate = 2 years

We need to find the interest that is paid back. We know that, simple interest is given by :

[tex]I=\dfrac{PRT}{100}[/tex]

Put all the values,

[tex]I=\dfrac{43800\times 4.8\times 2}{100}\\\\=\$4204.8[/tex]

So, the required interest is equal to $4204.8 .

Which statement best explains whether △ABC is similar to △DEF?
A) The triangles are not similar because 613≠820.
B) The triangles are similar because 613=820.
C) The triangles are similar because 820=1025.
D) There is not enough information to determine whether the triangles are similar.

Answers

A). They are not similar, because 6/13 is not equal to 8/20

For triangles to be similar, the ratios of sides need to be the same (shortest to shortest, middle to middle, longest to longest). The shortest sides are 6 and 13, respectively, the middle ones are 8 and 20. Because 6/13 is not equal to 8/20, the triangles are not similar.

The statement best explains whether △ABC is similar to △DEF is (A) The triangles are not similar because 613≠820.

What are similar triangles?

Similar triangles are triangles that have similar corresponding side lengths

The corresponding sides of the triangles are:

Triangle A        Triangle B

6                              13

8                              20

10                             25

Calculate the ratios

Ratio = 6/13

Ratio = 8/20

The ratios are not equal.

Hence, the triangles are not similar
