Find the area of this triangle. Round to the nearest tenth. 8m, 62°, 12m.

Answer:

Your points have the same x coordinates....this means that u have a vertical line which has an undefined slope. Being that the slope is undefined, you cannot write the vertical line in slope intercept or point slope form. Im not full sure this is right but maybe this will help understand something

Step-by-step explanation:

Answer:

The line has same x- values and different y- values.

It can have an equation, which is:

For any value of y, the line has x- value of 6.

Answer:

2.6+3.1+5.4 =21.1

if you have 20

subtract 21.1-20

then you have 1.1

since the difference is 1.1 then we say

21.1>20

Answer:

Step-by-step explanation:

For relations expressed as (input, output) or (x, y) pairs, the domain is the list of inputs, or x-values. The range is the list of outputs, or y-values. Yes, it is that simple. (We often like to arrange the lists in increasing order.)

__

1. Domain: {-1, 0, 1, 4}

  Range: {-6, 3, 5, 7}

__

2. Domain: {-1, 2, 3}

  Range: {3, 5, 7}

3. Domain: {-2, -1, 0, 1}

  Range: {0, 1, 4}

Answer:

10. f'(x) = (x/14) + (14/9)

11. f'(x) = - x + 2

12. f'(x) = 2x - 8

Step-by-step explanation:

The step to solving inverse is a simple trick. You must invert x and y.

For (10.) let f(x) = y

then y = 9x - 14

x = 9y - 14 (this is inverting x and y)

solving for y: x + 14 = 9y

therefore : y = (x/14) + (14/9)

You can do this for the others as well and using simple "solve for x" methods, you can solve for y which is f'(x).

ln(3) = k ln(e)

k = ln(3)

k = 1.09861

Hi! I'm happy to help!

Fractions are wholes that are split up. When you split the whole into more pieces, the pieces are smaller.

Due to the fact that 5/12 is split into more pieces than 5/11, and they have the same amount of pieces, 5/11 would be larger because of bigger pieces.

5/11 is bigger because it has bigger pieces.

I hope this was helpful, keep learning! :D

Answer:

The associative property can be used with multiplication and addition.

Examples:

2+(3+2) -> (2+3)+2 (Associative Addition)

2*(3*2) -> (2*3)*2 (Associative Mult.)

It does not work with division or subtraction.

2-(3-2) does not equal (2-3)-2

Please you didn't provide the coordinates of figure A and figure B, only the scale factor. If you provide the coordinates,I will be able to solve it.

Thank you.

Step-by-step explanation:

5(x-6)=8

5x - 30 = 8

5x = 8 + 30

5x = 38

X = 38/5

X = 7.6

The value of x is 7.6.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

5 (x - 6) = 8

Solve for x.

5x - 30 = 8

5x = 8 + 30

5x = 38

x = 38/5

x = 7.6

Thus,

x is 7.6.

Answer:

in this question, the mean would be the best measure for central tendency....

Step-by-step explanation:

because it is the measure that includes all the values in the data set for its calculation, and any change in any of the scores will affect the value of the mean. This is not the case with the median or mode.

So in conclusion your answer will be D.mean

Let start with some basic theory of quadratics

If  f(x)=ax2+bx+c  a,b,c ∈R  a≠0    f(x)=ax2+bx+c  a,b,c ∈R  a≠0  has   2    2   roots   r1    r1  and   r2    r2  than it can take the form f(x)=a(x−r1)(x−r2).f(x)=a(x−r1)(x−r2).

The maximum or minimum value of  f(x)    f(x)   is   M=−(b2–4ac)4a  M=−(b2–4ac)4a

If   a>0    a>0  then  M    M  is the minimum value and if   a<0    a<0   then   M    M  is the maximum value.

Lets go now to the question

Since  2    2  and   7    7  are the roots our function will be  f(x)=a(x−2)(x−7),  a∈R  f(x)=a(x−2)(x−7),  a∈R

so   f(x)=a(x2

therefore, the correct option is B

Answer:

x = (1/5)(y + 7)² + 3

Step-by-step explanation:

Given that,

→ y² + 14y - 5x + 64 = 0

Let's find the required solution,

→ y² + 14y - 5x + 64 = 0

→ 5x = y² + 14y + 64

→ 5x = y² +14y +49 + 15

→ 5x = (y + 7)² + 15

→ x = [(y + 7)² + 15]/5

→ [x = (1/5)(y + 7)² + 3]

Hence, it is the correct answer.

Answer:

10 months. Each plan will save 800 dollars.

Step-by-step explanation:

500 + 30x = y

300 + 50x = y

You want the months to give the same amount of money. The x has to be the same for both

500 + 30x = 300 + 50x        Subtract 300 from both sides

500 - 300 + 30x = 50x         Combine

200 + 30x = 50x                   Subtract 30x from both sides

200 = 50x - 30x                    Combine

200 = 20x                              Divide by 20

x = 10

So in 10 months time the amounts will be the same. How much will there be?

500 + 30*10 = 500 + 300 = 800

300 + 50*10 = 300 + 500 = 800

Additional comment

The doubling time for continuously compounded interest is 69.3 years divided by the interest rate in %. Here, that is 69.3/7.3 = 9.49 years. That means an investment of 10 years will be slightly more than double the original amount. 2×65,000 = 130,000, so choice A is in the right ballpark. The other numerical choices are not.
