Answer:

A. Cos θ = 16/42

Step-by-step explanation:

The angle the ladder makes with the floor = θ

Hypotenuse = length of the ladder = 42 m

Adjacent = Distance from the bottom of the ladder to the wall = 16 m

Therefore to find θ, we would apply the trigonometric function, CAH:

Cos θ = adj/hyp

Which is:

Cos θ = 16/42

B and C are correct.

**Answer:**

B and C

**Step-by-step explanation:**

A, when x = 0, y = 5

B, when x = 4, y = 3

C, when x = 12, y = -1

D, when x = 1, y = 9/2

Convert the equation into standard form.

25x^2 - 9y^2 + 200x + 18y + 166 = 0

**Answer:**

the answer is d (x+4)^2/9 - (y-1)^2/25

**Step-by-step explanation:**

its correct on edge

The **standard **form of the **given **equation is [tex]\dfrac{(x+4)^2}{9}-\dfrac{(y+1)^2}{25}=1[/tex]

**Expression **in maths is defined as the **collection **of the numbers variables and **functions **by using signs like addition, subtraction, multiplication, and division.

Begin by **grouping **the x terms together and the** y terms **together, and getting the **constant **on the other side of the **equals **sign:

25x² +200x - 9y² +18y = -166

Now we need to **complete **the square on the **x terms** and the **y terms. **Do this by first **factoring **out the leading **coefficient **from each, the **25 **from the **x's **and the 9 from the **y's:**

25(x² +8x) - 9 (y² +2y) = -166

Now **take **half the linear term in each set of **parenthesis**, square it, and add it to both sides, **remembering **the multiplier outside (the **25** and the 9). Our x **linear **term is **8.** Half of **8 is 4,** and 4 squared is** 16**, so we add a 16 into the **parenthesis **with the x's; our y **linear term** is 2. Half of **2 is 1 **and 1 **squared **is 1, so we add a 1 into the **parenthesis **with the y's:

25(x² +8x + 16)-9(y²+2y +1) = -166+400-9

Note the **400 **and -9 on the right side now. **25** times 16 is **400**; we didn't just add in a **16**, we have to multiply the **scalar **number into it before we know what we **really **added in. And the **-9 **comes from **multiplying **the -9 times 1.

The **reason **we do this is to get the **perfect **square binomials on the left that we **created **while completing the **square**:

25(x+4)² - 9 (y+1)²= 225

Now, finally, we will **divide **both sides by **225 **to get this **conic **into the **standard **form:

[tex]\dfrac{(x+4)^2}{9}-\dfrac{(y+1)^2}{25}=1[/tex]

This is a **hyperbola **with a horizontal **transverse **axis and a center of** (-4, -1)**. The reason we know it's **not **an ellipse is because an **ellipse **will always have a **+ sign** separating the** x-squared** from the** y-squared **whereas a **hyperbola **always has a** - sign **separating them. And we also know it's not a **circle **because the values of the **leading **coefficients weren't the **same**.

Therefore the **standard **form of the **given **equation is[tex]\dfrac{(x+4)^2}{9}-\dfrac{(y+1)^2}{25}=1[/tex]

After the end of everyday, a production plant's maintenance crews check on the machinery and grade each item's state of repair. A particular robot arm can be given ve grades: Excellent, Good, Satisfactory, Watch, Failed. If the robot arm is tagged with a Failed grade, a crew will be sent the next day to repair it. There is about a 60% chance the crew will be successful in repairing the arm back to an Excellent condition. Otherwise, they have to try again the next day to x it. The general wear and tear of operation causes at most a single level of deterioration a day and this grade decrease happens about 25% of the time. During the day, the operators can tinker with the arm and are able to increase (if possible) the repair grade level 10% of the time. The operators cannot improve a Failed arm. Management wants to model the daily grade level of a robot arm.

When you solve the system shown by the elimination method, which statement is true?

y + 3x = 10

−y − 3x = 10

**Answer:**

**B. There is no solution; x and y are eliminated and you get the false statement 0 = 20.
**

**Step-by-step explanation:**

According to the elimination method, the two equations are

y + 3x = 10

−y − 3x = 10

If we solve it

0 = 20

As x and y would be eliminated due to positive and negative signs

It is to represent the area of the park.

**Step-by-step explanation:**

The length and width of the park would be inches, miles, or meters to describe the linear aspect of the park.

If the park was, for example, 2 miles long and 3 miles wide, you would say the park is 6 miles squared. This is to describe the square area of the park. Square units could be replaced by squared acres, miles, or meters depending on the size of the park. This is to represent the area of the park.
