Answer:

By freeing slaves in the Confederacy, Lincoln was actually freeing people he did not directly control. The way he explained the Proclamation made it acceptable to much of the Union army. He emphasized emancipation as a way to shorten the war by taking Southern resources and hence reducing Confederate strength.

Work Shown::

1/2 = 0.5

7 & 1/2 = 7 + 1/2 = 7 + 0.5 = 7.5

7.5% = (7.5)/100 = 0.075

She invests P = 73000 dollars at an interest rate of r = 0.075

Let x be some unknown number of years. So t = x.

She wants her investment to be worth $75,760, so this means she wants to earn 75760-73000 = 2760 dollars in simple interest. Let i = 2760

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

Apply the simple interest formula to help solve for x

i = P*r*t

2760 = 73000*0.075*x

2760 = 5475x

5475x = 2760

x = 2760/5475

x = 0.5041095890411

This represents the approximate number of years that must elapse for her to get this amount of simple interest.

Let's multiply by 365, since there are 365 days in a year (ignoring leap years) to get

365*0.5041095890411 = 184.000000000001

Due to rounding error, that 1 at the very end likely shouldn't be there. So it looks like exactly 184 days must elapse so that she earns that amount of money.

If she started on March 1, then adding on 184 days leads to September 1.

I recommend looking at a "Day of Year Calendar". Note on this calendar there are numbers for each day. In this case, march 1st occurs on the 60th day of the year while September 1st occurs on the 244th day of the year. Then note how 60+184 = 244. The day of year calendar is a quick way to scroll forward or backward in time on any day. Many online calculators provide an even faster method. The slowest method is to count the number of days on a traditional calendar, but I don't recommend this.

The sentence with proper subject-verb agreement is the student as well as the teacher want to go to the museum. In this sentence, the subject is what we call a compound subject, meaning that the verb refers and agrees with more than just one singular word.

The compound subject is "student" and "teacher" and they are connected by "as well as", which functions as a coordinating conjunction would. That's why the verb should conjugate in its plural form.

Option A is incorrect because the structure inside parentheses is not related to the verb and does not influence its conjugation. Options C and D have a verb in the singular form for a compound subject - that would demand a plural conjugation.

The average rate of change over is 1.

Given that;

the function is,

⇒ g (t) = - (t - 1)² + 5

Hence, We need to determine the average rate of change over the interval - 4 ≤ t ≤ 5.

The value of G(-4):

The value of G(-4) can be determined by substituting t = -4 in the function

⇒ g (t) = - (t - 1)² + 5

Thus, we have,

⇒ g (t) = - (-4 - 1)² + 5

⇒ g (t) = - 20

Thus, the value of G(-4) = -20

The value of G(5):

The value of G(5) can be determined by substituting t = 5 in the function , we get,

⇒ g (t) = - (t - 1)² + 5

⇒ g (t) = - (5 - 1)² + 5

⇒ g (t) = - 11

Thus, the value of G(5) is, -11

Now, Average rate of change:

The average rate of change can be determined using the formula,

⇒ G(b) - G (a) / (b - a)

where, a = - 4 and b = 5

Substituting the values, we get,

⇒ G(5) - G (-4) / (5 - (-4))

⇒ ( - 11 - (- 20)) / 9

⇒ 9/9

⇒ 1

Thus, the average rate of change over the interval is. 1.

The value of the missing side lengths x and y are 5√2 and 5 respectively.

The figure in the image is a right triangle.

Angle θ = 45 degree

Hypotenuse = x

Opposite to angle θ = y

Adjacent to angle θ = 5

To solve for side x and side y, we use the trigonometric ratio.

Note that:

Cosine = adjacent / hypotenuse

tangent = opposite / adjacent

Solving for x:

Cosine = adjacent / hypotenuse

Plug in the values

cos( 45 ) = 5/x

x = 5 / cos( 45 )

x = 5√2

Solving for side y:

tangent = opposite / adjacent

Plug in the values

tan( 45 ) = y/5

y = tan( 45 ) × 5

y = 5

Therefore, the value of side length x is 5 units.

Answer:

29 candy bars.

Step-by-step explanation:

First, let's find the cost of all of the movie passes:

13 x 9.5 = 123.5

Second, let's find the cost of the 3 gift cards:

25 x 3= 75

Now, let's add the costs up and subtract the total from 250:

123.5 + 75 = 198.5

250 - 198.5 = 51.5

So our total is 51.5 dollars. Now let's divide that by 1.75.

1.75 x 29 = 50.75

Since 1.75 x 30 = 52.5, the greatest number of candy Marcy can be is 29 candy bars.

According to the assumption the translated triangle would have vertices at (4,0), (6,2), and (5,-1).

Given,

To translate a triangle 3 units to the right and 2 units down, we would take each point of the original triangle and add 3 to the x-coordinate and subtract 2 from the y-coordinate.

For example, if the original triangle has vertices at (1,2), (3,4), and (2,1), the translated triangle would have vertices at:

(1+3, 2-2) = (4,0)

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

(2+3, 1-2) = (5,-1)

So, the translated triangle would have vertices at (4,0), (6,2), and (5,-1).

Answer:

  both functions have the same graph

Step-by-step explanation:

The first function is described in terms of its slope and y-intercept, so can be written in slope-intercept form as ...

  y = mx + b . . . . m = slope (-7/9); b = y-intercept (3)

  y = -7/9x +3

__

The second function is written in point-slope form:

  y -k = m(x -h) . . . . m = slope (-7/9), point = (h, k) = (18, -11)

  y +11 = -7/9(x -18)

If we rearrange the second equation to the form of the first, we get ...

  y = -7/9x +14 -11 . . . . eliminate parentheses, subtract 11

  y = -7/9x +3 . . . . . . . matches the equation of the first function

We have,

We can simplify the given expression as follows:

= (5X - 5Y) ÷ 8 - 1 ÷ (4X + 4Y)

Step-by-step explanation:

The total money paid for a meal of $100 with 7% sales tax, 20% tip and a coupon for 15% off is $112.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let us assume that the total cost of the meal shown in the table cost $100, hence:

Tax = 7% of sales = 0.07 * 100 = $7

Tip = 20% of sales = 0.2 * 100 = $20

Coupon = 15% = 0.15 * 100 = $15

Amount paid for meal = total cost + tax + tip - coupon = 100 + 7 + 20 - 15 = $112
