1.Given The Rotation Of Triangle ABC Shown Below, Determine The Counter-clockwise Angle Of Rotation That

Answers

Answer 1

Answer:

D. 50º

Step-by-step explanation:

According to the image below attached, blue lines represents line segments [tex]DB[/tex] and [tex]DB'[/tex], the red line creates a right angle regarding [tex]DB[/tex] (90º), where green line creates a flat angle with the same respect (180º). The angle between [tex]DB[/tex] and [tex]DB'[/tex] is less than 90º and 180º, meaning an acute angle. Therefore, the right answer is D.

Step-by-step explanation:

Use the distributive property to write an equivalent expression without parentheses.

9 (a + 8)

Check all that apply.
Distribute 9, by multiplication, to the variable, a, and to the constant, 8.
Write the two multiplications, 9(a) + 9(8)
The expression 9(a) is written as 9a.
The expression 9(8) equals 72.
The equivalent expression is 9a + 8.
The equivalent expression is 9a + 72.

The graph representing the volume of water in the pool over time is illustrated in the graph.

How to illustrate the graph?

The problem can be presented by a simple linear equation:

y =mx + b

Find the area of the rectangle.
(8x+5) yards
(8x-5) yards

Answers

Step-by-step explanation: To find the area, we can use the F.O.I.L. method.

Notice that these two binomials are identical except

that one has a plus and one has a minus.

These types of binomials are called conjugates.

If you're asked to F.O.I.L. two conjugates, you can  

ignore the outer and inner products,

knowing they will cancel each other out.

So the answer to this problem comes from the product

of the first terms and the product of the last terms.

So our answer is 64x² - 25.

Step-by-step explanation:

The equation to find a line is mx+b=y. In this case m is 5, and b is -2.

5x+-2=y

Since we want to find the x-intercept, y has to be 0.

So: 5x+-2=0

what I like to use when figuring these out(mainly for homework) is a website called Desmos. You basically just plug in whatever equation/expression in and it will graph it for you. My Algebra teacher even allows me to. So all I did was plug in each equation until it matched the graph presented. Hope this helps!

The equation represented by the graph is y=|x+1|

How to determine the equation?

The equation is an absolute value graph

The parent function of an absolute value graph is:

y = |x|

The above function is shifted to the left by 1 unit.

This transformation is represented by y=|x+1|

Hence, the equation represented by the graph is y=|x+1|

The measure of angle 1 will be equal to 68.

What are supplementary angles?

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet. The supplementary angle is defined as the angle having the sum of 180 degrees.

Given that there are two parallel lines intersecting one line at an angle of 112. The angle 1 will be calculated as:-

The angle will be calculated as follows:-

∠1 + 112 = 180

∠1 = 180 - 112 = 68

American officials wanted to avoid the problems that caused France to abandon the project. They wanted to protect workers from disease. An engineer, John F. Stevens, was sent to the work camp in Panama. He began building hospitals as well as water and sewage systems making the working conditions sanitary. He supported the camp doctors efforts to fight mosquitoes, the cause of malaria and yellow fever. All of these efforts helped to keep the workers healthy and focused on the task at hand.Using the Panama Canal Since the water level of the Pacific and Atlantic Oceans is not the same, a system of locks and gates had to be built in the canal. These locks are a pathway for ships to move from one ocean to the other. A lock is a giant box made of concrete. A ship must pass through three locks in the Panama Canal. Each lock holds millions of gallons of water. A ship moves into a lock, which is filled with water. Water is pumped into the lock or out of the lock. This raises or lowers the ship to the level of water in the next lock. The gates open, and the ship moves into the next lock. By early 1913, the canal was nearly complete. It took several months to fill the canal with water. On September 26, 1913, an old tugboat was the first ship through the canal. Thousands of people watched and cheered. The locks worked perfectly. In modern times, approximately 14,000 ships make the 50-mile trip through the canal each year. On average, the trip through the canal takes a ship 8 to 10 hours. The ship captain does not steer the ship through the canal. A specially trained canal pilot takes control of the vessel and expertly guides it through the canal. Time, money, and possibly even lives have been saved as ships use the shorter route from ocean to ocean provided by the canal. The Panama Canal, a highway of water, is a phenomenon.
