Answer:

The answer is below

Step-by-step explanation:

θ = 90° - 42° = 48°

The angle formed is a right angled triangle, therefore trigonometric identities can be used to find the length of the triangle sides.

tan(θ) = opposite / adjacent

tan(48) = 80 / h

h = 80 / tan(48)

h = 72.03 ft

h is the vertical distance from carl to the top of his house, to get his total height to the ground (H), we use:

H = h + height of house

H = 72.03 + 20

H = 92.03 ft

Therefore Carl is 92.03 ft high

Point-slope form:

[tex]\displaystyle y-3=-\frac{1}{3}(x-3)[/tex]

Slope-intercept form:

[tex]\displaystyle y=-\frac{1}{3}x+4[/tex]

Step-by-step explanation:

We want the equation in point-slope form and slope-intercept form that passes through the points (-3, 5) and (3, 3).

First, we will find the slope between the two points. By the slope formula:

[tex]\displaystyle m=\frac{5-3}{-3-3}=\frac{2}{-6}=-\frac{1}{3}[/tex]

Point-slope form is given by:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

We can choose either point. I'm going to let (3, 3) be (x₁, y₁). The slope m is -1/3. Therefore:

[tex]\displaystyle y-3=-\frac{1}{3}(x-3)[/tex]

Is the point-slope form*.

To find the slope-intercept form, we simply need to isolate y. Distribute:

[tex]\displaystyle y-3=-\frac{1}{3}x+1[/tex]

Adding 3 to both sides yields:

[tex]\displaystyle y=-\frac{1}{3}x+4[/tex]

This is slope-intercept form.

*If you use the other point, the point-slope form will be:

[tex]\displaystyle y-5=-\frac{1}{3}(x+3)[/tex]

Step-by-step explanation:

The Constitution gave the federal government the power to put down domestic rebellions, including slave insurrections. The framers of the Constitution believed that concessions on slavery were the price for the support of southern delegates for a strong central government.

Answer:

The North allowed the constitution to protect slavery because they belived that slavery was an unhuamne thing although all their production for industrialization did come from the south where the slaves worked on them.

Answer:

x=-3

Step-by-step explanation:

The axis of symmetry is the line that separates a parabola directly in half. It is measure on x axis because it is being split in terms of that number. Next, you identify the origin and find exactly where the parabola is in half and that is your answer. Another way to do this would be to identify the vertex of the parabola. The answer is the x coordinate of the location of the vertex. (The highest point of a parabola.)

Step-by-step explanation:

Answer:

x=0

Step-by-step explanation:

You must isolate the variable to solve for it, so subtracting 14 from the left is the first thing to do. This can be supported by using PEMDAS, whereas we are doing the inverse here to solve for something in the equation. This gives us 2x=0. Next, we have to divide by 2, which gives us x=0.

Answer:

Coords (-2,0)

Step-by-step explanation:

Translation means moving the point in the direction that is stated by the amount stated. Down means decreasing the number value along the y-intercept. So using simple math subtract 4 by 4 and you get 0. Since we don't move the left or right which means going along the x-intercept lines. We get (-2,0)

Answer:

[tex]3x+5y[/tex]

Step-by-step explanation:

Subtract (6x-3y) from (9x+2y):

[tex](9x+2y)-(6x-3y)[/tex]

This can also be seen as:

[tex](9x+2y)-1(6x-3y)[/tex]

Distribute the -1 to (6x-3y):

[tex](9x+2y)-1(6x)-1(-3y)\\\\(9x+2y)-6x+3y[/tex]

Simplify the parentheses:

[tex]9x+2y-6x+3y[/tex]

Group like terms:

[tex](9x-6x)+(2y+3y)[/tex]

Combine:

[tex]3x+5y[/tex]

This expression can't be further simplified. Therefore, 3x+5y is the answer.

Answer:

Hola its MEEEE

Step-by-step explanation:

Given:

Point D is the centroid of Triangle ABC and DE = 9.

To find:

The measures of CD and CE.

Solution:

We know that, centroid is the intersection of medians and it divides each median in 2:1.

In triangle ABC, CE is a meaning and centroid D divided CE in 2:1. So,

Let the measures of CD and DE are 2x and x respectively.

DE = 9                (Given)

[tex]x=9[/tex]

Now,

[tex]CD=2x[/tex]

[tex]CD=2(9)[/tex]

[tex]CD=18[/tex]

And,

[tex]CE=CD+DE[/tex]

[tex]CE=18+9[/tex]

[tex]CE=27[/tex]

Therefore, the measure of CD is 18 units and the measure of CE is 27 units.

The measure of CD and CE are 18 and 27 respectively

From the given diagram, the following are true:

Given that DE = 9

CD = 2(9)

CD = 18

Similarly;

CE = CD + DE

CE = 18 + 9

CE = 27

Hence the measure of CD and CE are 18 and 27 respectively

The counterexample shows that Heng's definition does not fully define a reflection is Heny fully defined a reflection. Option D

Consider the counterexample in which point M is above line r and the line itself is a vertical line.

Assume M is located at (0, 2) and that line r is the x = 1 line. Heng's definition states that point M', which has a midpoint L that is on line r, should reflect point M across line r.

However, point M' at (-1, 2) would be the reflection of point M across line r, which does not meet the requirement that the midpoint L lies on line r. Therefore, in this counterexample, Heng's definition does not adequately characterize a reflection.

Answer:

a. 2176782336 with repeated characters. 1402410240 with no repeated characters.

b. 7964171460 when all letters can be repeated, but not numbers. 118813760 when only one number and letters can be repeated.

I believe that the password with all letters able to repeat and numbers not being able to is the most secure password, because if someone were to guess the password there is a 1/7964171460 chance of guessing the password.

Step-by-step explanation:

A. Since there are 26 different letters and 10 different numbers, there are 36 characters we can type. If characters can be repeated then, there is 2176782336 different passwords, since on all six number there are 36 possibilities each. So, 36 x 36 x 36 x 36 x 36 x 36 or 36^6 is to evaluated to find the answer. If characters are not to be repeated, there are 1402410240 different passwords, since on the first number there are 36, second has 35, third has 34, fourth has 33, fifth has 32, and sixth has 31. So, 36 x 35 x 34 x 33 x 32 x 31 is to be evaluated to solve this.

B. Since all characters that are letters can be repeated, then there are 26 letters to use forever and 10 numbers you can use with a limit. So, 36 x 35 x 34 x 33 x 32 x 31 which is to be solved if only numbers were to be used, which is 1402410240. Then, you add that with 36 x 35^5 and 36 x 35 x 34^4 and 36 x 35 x 34 x 33^3 and 36 x 35 x 34 x 33 x 32^2. which will be 7964171460. If the password must contain one digit, then you must multiply 10 with 26^5. Since, there is 10 different digits to use for the first number and 26 letters to choose from for the other five. So, it will be 26^5 times 10 which is 118813760.
