help me with this question

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.

Answer:

I DON'T KNOW  the answer but hears the explanation.

Step-by-step explanation: So the total area of the composite shape is 30 + 20 = 50 cm². Note: An alternative method is to use the formula for the area of a trapezoid. Example 2 A circular shaped garden of radius 15m contains a square concrete region of side length 4m.

The area of the composite figure is,

⇒ 22 m²

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

The Composite figure is made up of a Triangle, and a trapezoid.

Now,

Area of triangle is;

⇒ A = 1/2 × 3 × 4

⇒ A = 6 m²

And, Area of trapezoid is,

⇒ A = (a + b) × h/2

⇒ A = (10 + 6) × 2/2

⇒ A = 16 m²

Thus, The area of the composite figure is,

⇒ 6 + 16

⇒ 22 m²

Answer:

1. -4a

2. -4

Step-by-step explanation:

The first problem is 4 x _ = -16a

So it has an a in it and we know 4 x 4 = 16 so it's 4a and its negative so -4a

The second problem is -4

Answer:

-3a/-4

Step-by-step explanation:

Answer:

1st question. A.

2nd question. D

Step-by-step explanation:

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.

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.

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

Answer:

6) 9

7) 9

8) 10

9) 13

10) negative

Step-by-step explanation:

6) The |#| means absolute value (the value of how far away a number is from 0). Any number in that position will be positive (e.g., |-9| is 9).

|-5|+4

5+4

9

--------------------------------------------------------------------------------------------------------------

7) A negative divided by a negative is always a positive.

-99/(-11)

99/11

9

--------------------------------------------------------------------------------------------------------------

8) This is a bit confusing. Anything within |#| must be solved before you change it into AVF (absolute value form).

|(-6)-4|

|-10|

10

--------------------------------------------------------------------------------------------------------------

9) Subtracting a negative makes it positive.

4-(-9)

4+9

10)  1 times -1 equals -1

2 times -2 equals -4

3 times -3 equals -9

if you know about% and if it is a number like 3 we will say and if it is like .3 that means that it is 30 % to 1/4th of 100 is 25

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% .

Step-by-step explanation:

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

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}.

Answer:

line and point

Step-by-step explanation:

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