Question 21>This Test: 26 Pts PossibleRe:MoreXExpress The Area Of The Figure, A, As Afunction Of One

Answers

Answer 1

Answer:

A(x) = 6x² + 26x

Step-by-step explanation:

A(x) = 4x ( x + 10 ) - 2x ( 8 ) + [tex]\frac{2x(x)}{2}[/tex] + [tex]\frac{2x(x+2)}{2}[/tex]

A(x) = 4x² + x² + x² + 40x - 16x + 2x

A(x) = 6x² + 26x

Need help with Part B - I need to find 2 solutions instead of 1

Can't use guess and check method

Answers

Answer:

See below

Step-by-step explanation:

Part AThe graph is attachedPart B|2x - 4| = mx + 1

It has only one solution when the line mx + 1 is parallel to one part of |2x - 4|.

As per graph, we see m = 2 makes it parallel to y = 2x - 4. This is the only solution.

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

Now, as I understand, you are looking for 2 solutions instead of one. It means the line mx + 1 will have 2 points of intersection with the line |2x - 4|.

One of those solutions is attached as well, where m = 1. And you may get many more options for this.

Given the sequence 1/2 ; 4 ; 1/4 ; 7 ; 1/8 ; 10;.. calculate the sum of 50 terms

Answers

Hint :-

Break the given sequence into two parts .Notice the terms at gap of one term beginning from the first term .They are like [tex]\dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}[/tex] . Next term is obtained by multiplying half to the previous term . Notice the terms beginning from 2nd term , [tex]4,7,10,13[/tex] . Next term is obtained by adding 3 to the previous term .

Solution :-

We need to find out the sum of 50 terms of the given sequence . After splitting the given sequence ,

[tex]\implies S_1 = \dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}[/tex] .

We can see that this is in Geometric Progression where 1/2 is the common ratio . Calculating the sum of 25 terms , we have ,

[tex]\implies S_1 = a\dfrac{1-r^n}{1-r} \\\\\implies S_1 = \dfrac{1}{2}\left[ \dfrac{1-\bigg(\dfrac{1}{2}\bigg)^{25}}{1-\dfrac{1}{2}}\right] [/tex]

Notice the term [tex]\dfrac{1}{2^{25}}[/tex] will be too small , so we can neglect it and take its approximation as 0 .

[tex]\implies S_1\approx \cancel{ \dfrac{1}{2} } \left[ \dfrac{1-0}{\cancel{\dfrac{1}{2} }}\right] [/tex]

[tex]\\\implies \boxed{ S_1 \approx 1 }[/tex]

[tex]\rule{200}2[/tex]

Now the second sequence is in Arithmetic Progression , with common difference = 3 .

[tex]\implies S_2=\dfrac{n}{2}[2a + (n-1)d] [/tex]

Substitute ,

[tex]\implies S_2=\dfrac{25}{2}[2(4) + (25-1)3] =\boxed{ 908} [/tex]

Hence sum = 908 + 1 = 909

One box of salt contains 2.5 pounds and costs $2.51. How much is the price per ounce? Round to the nearest cent.

Answers

Answer:

The price per ounce is  about 6 cents .

Step-by-step explanation:

2.5 pounds costs $2.51

      1 ounce cost $ ?

We need to convert the pounds to ounces so we can answer the question.

1 pound = 16 ounces

2.5 pounds = 2.5 *16 = 40 ounces

Substitute the 2.5 pounds by 40 ounces

40 ounces costs $2.51

     1 ounce cost $ ?

$? = (1 * 2.51)/ 40 = .06275 ≅.06

1 ounce is $.06 or  6 cents

Answers

Answer:

10

Step-by-step explanation:

f(x)=3x-1

g(x)= - 2x-4.  

g( f(-2))

First find f(-2)

Let x = -2

f(-2)=3(-2)-1 = -6-1 = -7

Now find g(-7)

g(-7) = -2(-7) -4 = 14 -4 = 10

Answer:

[tex]f(x) = 3x - 1 \\ g(x) = - 2x - 4 \\ g(f(x)) = - 2(3x - 1) - 4 \\ g(f(x)) = - 6x + 2 - 4 \\ g(f(x)) = - 6x - 2 \\ g(f( - 2)) = - 6( - 2) - 2 \\ g(f( - 2)) = 12 - 2 \\ \boxed{g(f( - 2)) = 10}[/tex]

g(f(-2)) = 10 is the right answer.

19) Dana has fillings in 4 of her 32 teeth. What percent of her teeth
have fillings? *
10.5%
12.5%
14.5%
15%

Answers

Answer:

12.5%

Step-by-step explanation:

The question stated that 4 of her teeths have fillings out of her 32 teeth. From this info, we can represent 4 and 32 in fraction form; we can write it as 4/32. Now all you have to do is write 4/32 as a fraction. Divide 4 by 32 = 0.125. Multiply 0.125 by 100 to get 12.5%. Therefore, the answer is 12.5%.

Hope this helps!

Can you mark me brainliest pls? (Only if you want, I won’t mind if you don’t)

Answer:

12.5%

Step-by-step explanation:

There are two ways to go about this:

One way...Set up a proportion

4/32 = x/100

You know that 32 is basically 100% and you are trying to figure out the missing percentage which is represented by "x"

All you have to do once you set up this proportion is to cross multiply...

32 · x = 32x

4 · 100 = 400

and you are left with:

32x = 400

Divide both sides to isolate "x"

x = 12.5

Thus, your answer would be 12.5%

Second Way...

You can divide 4 by 32.

4 ÷ 32 = 0.125

Then multiply by 100 to get the percent

0.125 · 100 = 12.5

And you get 12.5%
