. Which is a true statement about the transformation?

Answers

Answer: The orientation of the vertices was changed.

(x, y) ---> (x + 8, y - 3)

Step-by-step explanation: The triangle translation isn't on quadrant II, it's on quadrant I, so that answer choice isn't correct.  The triangle ABC translated 8 units right and 3 units down, not 8 units left and 3 units up.  Whenever you dilate, translate, rotate, or reflect triangles like ABC, the next triangle becomes A'B'C because it shows you that it's a transformation of the original triangle.  The orientation of the figure didn't change, because it didn't change shape, rotation, or size, so the orientation wasn't affected at all, just the vertices.  

The transformation is (x, y) ---> (x + 8, y - 3), because think of it like this.  I already said that the triangle translated 8 units to the right, which means that the triangle is translating 8 units in the positive direction to the right.  The triangle going 3 units down is in the negative direction, and that's why it's (x, y) ---> (x + 8, y -3).

Let me know if this is right! :)

Step-by-step explanation:

To start multiply everything in the expression by 2

[tex]0.5x^{2} -3x+2.5\\x^{2} -6x+5[/tex]

Now factor the trinomials for when a=1

So you must find two numbers that add to -6 and multiply to 5

Find the surface area 7m 15m 6m

Answers

Answer:

474 m²

Step-by-step explanation:

Surface area of a rectangular prism:

SA = 2(lw + lh + hw)

Given:

width (w) = 6 mlength (l) = 7 mheight (h) = 15 m

⇒ SA = 2(7 · 6 + 7 · 15 + 15 · 6)

         = 2(42 + 105 + 90)

         = 2(237)

         = 474 m²

Answer:

474 Sq m

Step-by-step explanation:

You have two sides that are 7m x 6m

(7*6)*2 = 84

You have two sides that are 15m x 6m
(15*6)*2 = 180

You have two sides that are 15m x 7m

(15*7)*2 = 210

84+180+210=474

A theater group made appearances in two cities. The hotel charge before tax in the second city was $1000 lower than in the first. The tax in the first city was 3. 5% and the tax in the second city was 7%. The total hotel tax paid for the two cities was $455. How much was the hotel charger in each city before tax?

Answers

By solving a system of equations we will see that the charge on the first city was $5,000, and on the second city, $4,000.

How much was the hotel charge in each city?

Let's define the variables:

C₁ = charge in the first city.C₂ = charge on the second city.

We know that:

C₂ = C₁ - $1000

And we also know that the total tax is $455, then we can write:

0.035*C₁ + 0.07*C₂ = $455

(this says that the total tax is $455)

So we have a system of equations:

C₂ = C₁ - $1000

0.035*C₁ + 0.07*C₂ = $455

We can replace the first one into the second to get:

0.035*C₁ + 0.07*(C₁ - $1000) = $455

0.105*C₁ - $70 = $455

C₁ = ($455 + $70)/0.105 = $5,000

And:

C₂ = C₁ - $1000 = $5,000 - $1,000 = $4,000

The charge in the first city is $5,000 and in the second city was $4,000.

Molly would be 1 years old.

Step-by-step explanation:

(h+3) will be Heidi's age then.

(h+3) = 2(m+3) :: given.

.

Subsitute what we know about m, which is it equal h-4.

.

(h+3) = 2(m+3)

(h+3) = 2m + 6

substitute m=h-4

(h+3) = 2(h-4) +6

h +3 = 2(h -4) +6

h +3 = 2h -8 +6

h +3 = 2h -2

h = 2h -8 +3

-h = -5

h = 5

Heidi is 5 years old now.

Answer: (0, 9) or x = 0, y = 9

Step-by-step explanation:

     The solution is the point of intersection.

Here, the lines intersect at the point (0, 9) in the format of (x, y) so we can pull out the answers x = 0 and y = 9.

Answer:

(0, 9)

Step-by-step explanation:

First we need to find the equations of each line!What I'd do is use the equation:gradient (m) = change in y ÷ change in xStarting with the left line, let's pick two coordinates that are on the lineI've picked: (-2, 5), (-3, 3)gradient (m) = (3 - 5) ÷ (-3 - -2) = -2 ÷ -1 = 2We can then use the equation y = mx + c  (m is gradient)y = 2x + cWe know we have the point (-3, 3) on this line(-3, 3) = (x, y)  so  x = -3  and  y = 3y = 2x       + c3 = 2 × -3 + c3 = -6 + cc = 9Finally, we can say y = 2x + 9

Doing the exact same steps for the other line...

y = -3x + 9Since we now have two  y = ... equationsWe can say y = yWhich is the same as2x + 9 = -3x + 9We rearrange to find x...5x = 0x = 0That gives us the x-coordinate of where the lines meet (the solution of the system of equations)We can then pick either equation to find the y-coordinate:y = -3x + 9y = -3 × 0 + 9 = 9So the solution we have is at the point (0, 9)!

Find the area of this figure

Step-by-step explanation:

well, I see one large rectangle (20×6), and 2 small triangles with their horizontal sides being (20-8-6)/2 = 3 m. and their vertical joined side being 10-6 = 4 m.

the total area is simply the sum of the rectangle and the 2 triangles.

the rectangle is

20×6 = 120 m²

each triangle is

we have 2 of them, so their combined area is 2×6 = 12 m².

A firm is considering projects s and l, whose cash flows are shown below. These projects are mutually exclusive, equally risky, and not repeatable. The ceo wants to use the irr criterion, while the cfo favors the npv method. You were hired to advise the firm on the best procedure. If the wrong decision criterion is used, how much potential value would the firm lose?.

Answers

If the wrong discion criterion is used, the potential lose in value for the firm is $209.07.

What is the correct decision criterion?

The  correct decision criterion is the net present value. Net present value is the present value of after-tax cash flows from an investment less the amount invested. The internal rate of return is the discount rate that equates the after-tax cash flows from an investment to the amount invested

What is the loss in value if the wrong decision criteria is used?

The net present vaue and the internal rate of return can be calculated using the financial calcuator.

Project S:

Cash flow in year 0 = $-1025Cash flow each year from year 1 to 4 = $380

I = 6%

NPV = 291.74

IRR = 17.86%

Project I:

Cash flow in year 0 = $-2150

Cash flow each year from year 1 to 4 = 765

I = 6%

NPV = 500.81

IRR = 15.78%

If the wrong criteria is used, Project S would be chosen.

Loss in value = 500.81 - 291.74 = $209.07.

Here are the cash flows used:

WACC: 6.00%

Year 0 1 2 3 4

CF S -$1,025 $380 $380 $380 $380

CF I -$2,150 $765 $765 $765 $765

As per the total length of the arc of a semicircle, the outer perimeter of this figure is 61.9 feet.

What is the total length of the arc of a semicircle?

A semicircle that has a radius of 'r' units, has the total length of it's arc is

= πr units

In the given figure, the semicircle has a diameter = 10 feet.

Therefore, the radius of the semicircle

= 10/2 feet

= 5 feet

Now, the total length of it's arc is

= πr units

= 3.14 × 5 feet

= 15.7 feet

Therefore, the outer perimeter of this figure is
