For which values of A, B, and C will Ax + By = C be a vertical line through the point (8, 6)?A. A = 1, B = 0, C = 6
B. A = 1, B = 0, C = 8
C. A = 0, B = 1, C = 6
D. A = 0, B = 1, C = 8

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (8, 6) with x- coordinate 8, thus

x = 8 is the equation of the vertical line

In comparison to

Ax + By = C, then

A = 1, B = 0, C = 8, that is

x + 0 = 8

x = 8 being the required equation

Answer:

$\cot x$

Step-by-step explanation:

It is required to find the parent function of the given graph.

Since, we know that,

Range of the functions, $\sin x$ and $\cos x$ is [-1,1].

So, the given graph cannot be obtained from the functions $\sin x$ and $\cos x$ .

Also, we know,

Range of the functions, $\csc x$ and $\sec x$ is $(-\infty,-1]\cup [1,\infty)$ .

Thus, the given graph cannot be obtained from the functions $\csc x$ and $\sec x$ .

So, we are left with the functions, $\tan x$ and $\cot x$ .

Moreover, as $\tan 0=0$

But, in the graph, function is going to infinity when x= 0.

Thus, the graph cannot be obtained from $\tan x$ .

Hence, the parent function is $\cot x$ .

Describe all situation where verticals angles are also supplementary?

Answers

see my previous answer to this same question. the vertical angles have to be right angles

To solve this, we need to know what vertical angles and what supplementary angles are. Vertical angles are each of the pairs of opposite angles made by two intersecting lines. And, by the Vertical Angles Theorem, we know that they have the same measure. Now onto supplementary angles. Supplementary angles are angles that add up to 180 degrees.

Let's say that one of the vertical angles is equal to x. That means that the other one is also equal to x, and their sum is 2x. Since we are trying to find out a situation where vertical angles are supplementary, or equal to 180 degrees, that means that 2x is equal to 180 degrees. This is satisfied only when x = 90 degrees, meaning that vertical angles are supplementary when they are right angles.

I'm not sure how to calculate 12.5% of £168 anyone that can help if so that'd be great!

Answers

percent means parts out of 100

12.5%=12.5/100=0.125

'of' means multiply

12.5% of 168 means
0.125 times 168=21

answer is 21

Round 6.95 to one decimal place

Answers

7, 5 makes the 9 go up to 10 but the 1 pushes up 6 to 7 and 0 goes after decimal making 7.0. sorry if that's confusing

it would be 7 because you underline the 9 and put an arrow to the 5 and 5 and up move up 1 4 and down stay the same so the 6 is to a 7 and the rest of the numbers are 0.

Sam measured the height of a window frame as 5.23 feet, but the actual height was 6 feet. What is the percentage of error in Sam's measurement?

Answers

Answer: 12.83%

Step-by-step explanation:

Given : Sam measured the height of a window frame as 5.23 feet, but the actual height was 6 feet.

i.e. Estimated height = 5.23 feet

Actual height = 6 feet

Then, the percentage of error in Sam's measurement will be :-

$\%\text{Error}=\frac{|\text{Estimated height-Actual height}|}{\text{Actual height}}*100\n\n=(|5.23-6|)/(6)*100\n\n =(0.77)/(6)*100\n\n=12.8333333333\approx12.83\%$
