Answer 1

sin(45degrees) or BC/AB is 1/sqrt2(that's the value of sin45 degrees I recommend you to memorize this.)

x/12=1/sqrt2

x*sqrt2=12

x=12/sqrt2

Now rationalize this fraction to make the answer more formal.

x=12sqrt2/2(I multiplied both top and bottom by sqrt2)

Now simplify

x=6sqrt2

Question done! answer is C 6 square root of 2

Jake is a factory manager for a company that produces batteries. Occasionally, some are found to be defective. Based on previous results, Jake
estimates that 12 batteries will be defective for a certain month. However, 10 were actually defective. What is the percent error of Jake's estimate?

Answers

Answer:
20%

Explanation:
The formula for percent error is (accepted value - experimental value) / accepted value x 100. If you want to check plug that formula into a calculator. Work is shown below. 10-12 = -2. -2/10 = -0.2. -0.2 x 100 = -20. -20 x -1 = 20


20%

The percent error of Jake's estimate is 16.6 % when he found 10 were actually defective out of 12 batteries.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Mili obtained a score of 57% on her exam, that corresponds to 67 out of 100. It is expressed as 57/100 in fractional form and as 57:100 in ratio form.

Jake calculates that 12 batteries will be faulty during the month given in the question.

To determine the percent error which is the percentage of the difference between the accepted value and the experimental value.

As per the given condition, the required solution would be as:

⇒ [(12  - 10)/12] × 100

= [(2/12)] × 100

= [1/6] × 100

= 0.166× 100

= 16.6 %

Thus, the percent error of Jake's estimate is 16.6 %.

step 2. for the input x, there can only be one output or result y.

step 3. #1 is a function because for each x there is only one y.

step 4. #2 and #3 are functions also.

step 5. #4 is not a function because (1, 1) and (1, -1) says x is 1 but the y is both 1 and -1 (2 values)

2= - 7/4 + 1/4 x

Answers

Answer:

What you need to do is to solve. 2 = -7/4 + 1/4 x

You can try to have same denominator in all numbers to be able to multiply the right and left side by it and remove it

We can write it like this:

8/4 = -7/4 + 1/4  x

We multiply by four the two sides  and get

8 = -7 + x

We can sum 7 to both sides

8 + 7 = x

x= 15

We can replace to see if it's correct

-7/4 + 1/4 * 15 = -7/4 + 15/4 = 8/4

What is a transformation of a shape?

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the structure and/or location of the object.

From before the refers to the object's initial condition, and Picture, after transformation, refers to the object's ultimate structure and location.

Rotation does not change the shape and size of the geometry. But changes the orientation of the geometry.

The rectangle is in the first quadrant then the coordinate of the vertices of a rectangle will be positive (x, y).

The rectangle is rotated 180º counterclockwise about the origin.

The rectangle will be in the third quadrant then the coordinate of the vertices of the rectangle will be negative (-x, -y).

Thus, the ordered pair is a vertex of the rectangle’s image will be (-4, -1). Then the correct option is B.

More about the transformation of the shape link is given below.
