Answers

113.5 and 125.5 I think
Interest = (principal or amount invested) • (interest as a decimal) • (time in years)
I = (100)•(0.045)•(3) = $13.50
and
I = (100)•(0.045)•(5) = $22.50

WILL MARK BRAINLIEST Which table represents a relation with a domain of (-1, 2} and a range of (3,5)?

Answers

Answer:

C

Step-by-step explanation:

Second table represents the relation with a domain of {-1, 2} and a range of {3, 5}.

What do you mean by domain and range of a function?

For any function y = f(x), Domain is the set of all possible values of y that exists for different values of x. Range is the set of all values of x for which y exists.

Given is a relation with a domain of (-1, 2) and a range of (3, 5)

It can be seen that second table represents the relation with a domain of {-1, 2} and a range of {3, 5}.

Therefore, second table represents the relation with a domain of {-1, 2} and a range of {3, 5}.

A scatter plot is shown below. Which equation would best describe the line of best fit for the scatter plot?
y = 2x + 1
y = 2x
y = x + 1
y = -2x - 1 1​

Answers

Answer:

Scatter plot with line of best fit of y equals 0.75x plus five.

The line of best fit is y = 0.75x + 5.

Choose the best representation for the slope.

The slope of the line of best fit shows that each additional minute, the distance increases by 0.75 feet.

The slope of the line of best fit shows that each additional minute, the distance decreases by 5 feet.

The slope of the line of best fit shows that each additional minute, the distance decreases by 0.75 feet.

Question one is last option between 8 and 9

Answer:

question 1: it is between 8 and 9. question 2: option B.

Step-by-step explanation:

1. since the closest value that IS a squarable number is 64, the square root of 64 is 8. because 66 is greater than 64, we can estimate that the square root of 66 is between 8 and 9.

2. to solve this, we can take the square root of the numbers to begin.

the square root of 25 is 5 (because 5x5=25)

the square root of 16 is 4

20 is actually not squarable, so we can estimate that it is a little greater 4.

the answer would be √16, √20, 4.85, √25

it would be option b.

12. A chemist has 40 mL of a solution that is 50% acid. How much water should he add to make
a solution that is 10% acid?
Total Amount x % Acid = Amount of Acid
Total Amount
% Acid
Amount of Acid
Original Solution
Water
New Solution

Answers

Answer:

Volume of pure Acid in -50- LITRES of the solution= 10- litres. Let “V”- litres of water be added, then

Therefore 10= (50+ V) x8/100 .

So 10= 4 + 8V/100

8V/100 = 10–4= 6

So V= 6 x 100/8= 600/8= 75- LITRES.

So on adding 75- litres of water to the acid solution, the percentage of acid drops to 8% .

Check: Percentage of acid in 125- LITRES of acid solution, which contain 10- LITRES if pure Acid

= 10/125 x 100= 8% .

1st question. A.

2nd question. D

Step-by-step explanation:

Write each Quadratic function in standard form. The 2 picture is my notes to help with the answer.

Answers

Answer:

33) 4x² + 8x + 1

35) -2x² + 36x - 147

         

Step-by-step explanation:

#33: f(x) = 4(x+1) ² - 3

f(x) = 4(x+1) ² - 3

First Step: Multiply (x+1) (x+1)

(x + 1)² or (x+1)(x+1) is a one real double.

A one real double means that there is only one real solution

(x + 1) (x + 1) = x² + 2x + 1

Second Step: Multiply x² + 2x by 4

4(x² + 2x + 1) = 4x² + 8x + 4

Final Step: Put -3 in the Quadratic Function and do -3 + 4 to get your constant

4x² + 8x - 3 + 4

= 4x² + 8x + 1

#35: f(x) = -2(x - 9) ² + 15

First Step: Multiply (x - 9) (x - 9)

Remember, (x - 9) ² or (x - 9) · (x - 9) is a one real double, meaning that there is only one real solution.

(x - 9) (x - 9) = x² - 18x + 81

Second Step: Multiply by -2

-2 (x² - 18x + 81) = -2x² + 36x - 162

Final Step: Add the constant by 15 in the equation. (Hint: the constant is -162)

-2x² + 36x - 162 + 15

= -2x² + 36x - 147

This is how you convert the function into standard form. Hope this helps.

Answers

Answer:

Step-by-step explanation:

The kind of symmetry the figure given above posses is a line and point symmetry.

What is point symmetry?

A point Symmetry also known as origin symmetry is a Symmetry which occurs when every part of an object has a matching part. That is, the same distance from the central point but in the opposite direction.

Given that;

The objects looks the same when viewed from opposite directions.

We know that;

A line of symmetry is a line that cuts a shape exactly into two equal half. That is, if you fold the shape along the line, both halves would match exactly.

Therefore, the figure given above has both point and line Symmetry.
