Answer:

  625

Step-by-step explanation:

The ordered pair is an (x, y) pair. You are given the value of x. Put it in the equation and do the arithmetic.

  y = 5^4 = 625

The ordered pair is (4, 625). The missing value is 625.

_____

Additional comment

The exponentiation function on many calculators is done using a key labeled ...

  [tex]\boxed{y^x}[/tex]

You can do it the long way by recognizing that 5^4 = 5·5·5·5 or 25·25.

A person had $17,000 invested in to accounts One paying 7% simple interest And one paying 8% simple interest. How much was invested In each account if the interest rate after one year is $1356?

Answers

Answer:

A1 7% = $400 & A2 8% = $16,600

Step-by-step explanation:

A1 * 7% + A2 * 8% = 1356

A1 + A2 = 17000

A1 = 17000 - A2

(17000 - A2) * 0.07 + A2 * 0.08 = 1356

1190 - 0.07 A2 + 0.08 A2 = 1356

1190 + 0.01 A2 = 1356

0.01 A2 = 166

A2 = 16600

A1 = 17000 - A2

A1 = 17000 - 16600

A1 = 400

What is the distance between the points (2, -3) and (-6, 4) on the coordinate
plane?
A. 4.12 units
B. 3.87 units
C. 10.63 units
D. 8.06 units

Answers

Answer:

C) 10.63 units.

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We have the two points (2, -3) and (-6, 4). Let (2, -3) be (x₁, y₁) and let (-6, 4) be (x₂, y₂). Substitute:

[tex]d=\sqrt{(-6-2)^2+(4-(-3))^2}[/tex]

Simplify:

[tex]d=\sqrt{(-8)^2+(7)^2}[/tex]

Evaluate:

[tex]d=\sqrt{64+49}=\sqrt{113}\approx10.63\text{ units}[/tex]

Our answer is C.

Lana and Jeff each randomly surveyed 15 students about their favorite types of movies. Are these samples representative of the school population? Explain.

No, the samples are not large enough to be representative.

Yes, both samples are random, so they are representative.

No, the samples might include some of the same people, so they are not representative.

Yes, the samples do not include the same people, so they are representative.

Answers

Answer:

D but see below.

Step-by-step explanation:

This question is badly thought out. 15 might be enough to be representative if the school only contains about 100 people.If B is true then it would be the answer.If D was true, it would be the answer. If C was true, it could be the same answer.

So you have a question that has no clear answer. If Jeff took grade 11 and Lana took grade 12, that would make the answer much clearer. At least there would be no duplicates.

If you could refine the question a little more, you might get a clearer answer. I don't think this question should be asked and I sure don't think you should try and give an answer.

However that's not how schools work. So I would pick D, but by some bizarre method, the asker (like edge) might think of a way to make A B or C true.

What’s the slope and equation

Answers

Answer:

slope = -5 equation= y=-5x+100

Step-by-step explanation:

pick the x and y intercepts as your points to find the gradient that is

(20,0) and (0,100)

slope =∆y/∆x

=100/-20

= -5

take point(20,0) and (x,y) to find equation using the slope

equation becomes y= -5x+100

The last of these relations can be used to find x:

  x = 35°/7° = 5

The second of the relations can be used to find y:

The quotient obtained by dividing 4x²+3x+2 will be 4x + 15 hence option (A) will be correct.

What is the equation?

An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraint.

Given that

dividend  =  4x²+3x+2

divider = x -3

⇒ (x - 3) / 4x²+3x+2

⇒ (x - 3) / 4x²+3x+2

→ First it will goes for 4x time so 4x × (x - 3) = 4x² - 12x

Quotient = 4x

so (4x²+3x+2) - (  4x² - 12x ) = 15x + 2

(x - 3) / 4x²+3x+2

→ Second time it goes for 15 so 15 × (x - 3) = 15x -45

Quotient = 15

so  (15x + 2 ) - (  15x -45 ) = 47

Hence, 47 will be the remainder and the quotient will be (4x + 15).

Step-by-step explanation:

r - # of rows

(34) * (46) = 1564

(46) = (34) + 12

3 3/8- 9/8 give your answer as a mixed number

Answers

Answer:

2 1/4

Step-by-step explanation:

We have to make the first value into an improper fraction, which makes 3 3/8 into 27/8. Now we subtract 9 from 27, giving us 18. This 18 is still over the common denominator of 8. 8 goes into 18 twice with 2 left over. So we have our mixed number as 2 2/8, which can be simplified to 2 1/4.

1. Multiply 8 x 3 to find the value of 3 whole lots of eighths. This is 24, or 24/8, since there are 24 eighths.
2. To convert 3 3/8 into an improper fraction, do 24/8 + 3/8 = 27/8.
3. Now you can do 27/8 - 9/8, which is 18/8.
4. 18/8 cancels down to 9/4 if you divide both sides by 2.
5. Now, you can convert your answer into a mixed number by dividing 9 by 4 and putting the remainder over 4. 2 x 4 = 8, so you have two whole fourths and 1/4. Hence, your final answer is 2 1/4.

FYI, if you left your improper fraction as 18/8, you would still yet the same answer, because 2 x 8 = 16 and 18-16 = 2, so you would get 2 2/8, which cancels down to 2 1/4.

Hope this helped :)
