Point D is at (3,-4) and is translated 5 units up

Answers

Answer:

Quadrant II - +

Step-by-step explanation:

3,-4 translated 5 up is 3,1 then 4 units left is -1,1

Explanation needed it the answer

Answers

Answer:

8 units

by step explanation:

Since AB and DC are parallel to each other;

Then x + 2x = 180°

3x = 180°

x = 180/3 = 60°

∆ABC = 60° and ∆ ADC = 120°

∆BAD = 60° (adjacent angles of a trapezoid add up to 180°)

As shown in the figure attached, part of line AB is equal to 3 units and part is equal to: (c) units * 2 .

[tex] \frac{c}{5} = \cos(60) = \frac{1}{2} [/tex]

c = 2.5 units

Hence length AB is equal to; 2(2.5) units + 3 units = 8 units

7. If F(x) = f(g(x)), where f(-2) = 8, f'(-2) = 4, f'(5) = 3, g(5)=-2, gʻ(5) = 6.. Find F'(5)

Answers

Step-by-step explanation:

I'm going to lay this out in a chart so it's a little easier to see:

F(x) = f(g(x))

x | f (x) | f ' (x) | g (x) | g ' (x)

--------------------------------------

-2 | 8 | 4 |

5 | | 3 | -2 | 6

Remember the chain rule, which says

(f (g (x))) ' = g ' (x) f ' (g (x))

When they ask for F ' (5), they are asking for (f (g (x))) ' when x = 5.

Using the chain rule, that's

F ' (5) = g ' (5) f ' (g (5))

We can simplify using the numbers provided.

F ' (5) = (6) f ' (-2)

F ' (5) = (6) (4)

F ' (5) = 24

I hope that helps!

The required simplified solution of the F'(5) is 24

Given that,
F(x) = f(g(x)), where f(-2) = 8, f'(-2) = 4, f'(5) = 3, g(5)=-2, gʻ(5) = 6..
To determine F'(5),

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
F(x) = f(g(x))
Now,
F'(x) = (f (g (x))) '
Following the chain rule
F'(x) = g ' (x) f ' (g (x))
Now,
x = 5
F'(5) = g'(5)f'(g(5))
substitute the value in the above equation,
F'(5) = 6 × f'(-2)
F'(5) = 6 × 4
F'(5) = 24

Thus, the required simplified solution of the F'(5) is 24.

the scale from a map to actual distance is 2.5 cm to 620 miles the distance on the map between Chicago and Boston is about 3.5 cm what is the distance between Chicago and Boston​

Answers

Answer:

868 miles

Step-by-step explanation:

cm to miles ? are you sure you got the problem description right ? because cm are part of the metric system (mm, cm, meters, kilometers), while miles are part of American/ UK systems. and they don't deal with cm.

but ok, so, we will not deal with conversion rates, we will just apply the scale factors.

2.5 cm <-> 620 miles

3.5 cm <-> ? miles

that is determined by the factor to go from 2.5 to 3.5 cm. the same factor then had to be applied to the miles.

2.5 × f = 3.5

f = 3.5 / 2.5 = 7/2 / 5/2 = 7/2 × 2/5 = 7×2 / 2×5 = 7/5

=>

620 × 7/5 = 868 miles

a window is 9ft long. It is x feet longer than it is high. What is the height of the window.

Answers

Length of the window = 9ft
The length is x feet more than the height
Therefore, the height is (9-x) ft

The height of the window is 9-x feet.

Given that, a window is 9 ft long. It is x feet longer than it is high.

We need to find what is the height of the window.

What is an expression?

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Here, the length of the window = 9 ft

Then, the height of the window = x feet smaller than the length = 9-x feet

Therefore, the height of the window is 9-x feet.

A long distance runner does a first lap around a track in exactly 50 seconds. As she tires each subsequent lap takes 20% longer than the previous one. How long does she take to run 3 laps?

Answer:

  182 seconds, or 3 minutes 2 seconds

Step-by-step explanation:

The second lap takes ...

  (50 s)(1 +20%) = (50 s)(1.2) = 60 s

The third lap takes ...

  (60 s)(1.2) = 72 s

The three laps take 50 +60 +72 = 182 seconds, or 3 minutes 2 seconds.

At Chase Bank, you earned $50 in interest last year. If the interest rate is 4.5% and
your money was in the account for one year, what was your principal deposit, rounded to
the nearest dollar?

Answers

Answer:

$1,111

Step-by-step explanation:

Let x = principal amount

x multiplied by 1.045 will equal the final amount

Since 50 was earned, x + 50 will also equal the final amount

1.045x = x + 50

Let's move the x terms to left side by subtracting both sides by x

1.045x = x + 50

- x        - x

0.045x = 50

Divide both sides by 0.045 to isolate the x variable

0.045x/50 = 50/50

x = 1,111.111111111
