Answers

Answer 1

Answer:

−4x^2 + 10x+ 4

Step-by-step explanation:

that is the simplifyed version of the expression

Answer 2

Answer: The answer is −4x−9.8

Step-by-step explanation:

−7x−9−−4.2+3x−5

The opposite of −4.2 is 4.2.

−7x−9+4.2+3x−5

Add −9 and 4.2 to get −4.8.

−7x−4.8+3x−5

Combine −7x and 3x to get −4x.

−4x−4.8−5

Subtract 5 from −4.8 to get −9.8.

−4x−9.8

Select the polynomial that is a perfect square trinomial. 9x2 9x 1 36b2 − 24b 8 16x2 24x 9 4a2 − 10a 25.

Answers

The polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.

What is square?

The square can be defined as a two-dimensional figure that has 4 equal sides.

Given are the equations of the areas of the polynomial.

Option C: [tex]16 x^2 + 24x +9[/tex]

We can write the above equation as,

[tex](4x)^2 + 2 \times 4x \times 3 + (3)^2[/tex]

[tex](a+b)^2 = a^2 + 2ab+b^2[/tex]

Here a = 4x  and b = 3, so

[tex]16x^2 + 24x+9 = (4x+3)^2[/tex]

The simplification of the area of a polynomial is (4x+3)^2 which represents the area of a square.

Hence the polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.

What is the statistics Population?

In statistics, a population is the entire group that you want to draw conclusions about. Whereas, a sample is the specific group that you will collect data from.

Now, the family committee want to select a movie that will appeal to families with young children. Thus, it will be best for them to ask the parents of children as that will be a true representation of what the families would like to watch.

In conclusion, the only correct option is option C to ask 100 parents at the local playground

School X and School Y play eachother in a competiton.

School X has eight more points than School Y
School X has three times as many points than School Y

How many points does each school have?

Answers

Answer:

school x = 12

school y = 4

Step-by-step explanation:

School X has eight more points than School Y.

School X has three times as many points as School Y .

Writing these statements in terms of equation 

x = y + 8  

 x = 3 y

Substituting the value of x in y, we get

3 y = y + 8

Taking variable on left side of equation

3 y – y = 8 (subtract y from both sides)

2 y= 8 (divid 2 from both sides)

y = 4

then plug in y to the first equation

x= y + 8

x= 4 + 8

x= 12

Use the given information to find (a) sin (s +t), (b) tan (s+t), and (c) the quadrant of s+t cos s=3/5 and cos t= 15/17, s and t quadrant I

Answers

Step-by-step explanation:

Let find the other trig function first, just sin s and sin c.

Use pythagoren identity to find sin a.

[tex]1 - \cos {}^{2} (s) = \sin {}^{2} (s) [/tex]

cos s=3/5 so cos^2(s)=9/25

[tex]1 - \frac{9}{25} = \sin {}^{2} (s) [/tex]

[tex] \frac{16}{25} = \sin {}^{2} (s) [/tex]

[tex] \frac{4}{5} = \sin(s) [/tex]

Since this is in the first quadrant, it is positve.

Let do the the same thing for sin t.

[tex]1 - \frac{169}{289} = \sin {}^{2} ( {}^{} t) [/tex]

[tex] \frac{120}{289} = \sin {}^{2} (t) [/tex]

[tex] \frac{2 \sqrt{30} }{17} = \sin(t) [/tex]

Now, we can compute

a.

[tex] \sin(s + t) = \sin(s) \cos(t) + \cos(s) \sin(t) [/tex]

[tex] \frac{4}{5} \times \frac{13}{17} + \frac{3}{5} \times ( \frac{2 \sqrt{30} }{17} )[/tex]

[tex] \frac{52}{85} + \frac{6 \sqrt{30} }{85} [/tex]

[tex] \sin(s + t) = \frac{52 + 6 \sqrt{30} }{85} [/tex]

b

[tex] \tan(s + t) = \frac{ \tan(s) + \tan(t) }{1 - \tan(s) \tan(t) } [/tex]

Tan s is 4/3

Tan t is 2 times root of 30/ 13

So we have

[tex] \frac{ \frac{4}{3} + \frac{2 \sqrt{30} }{13} }{1 - \frac{8 \sqrt{30} }{39} } [/tex]

[tex] \tan(s + t) = \frac{52 + 6 \sqrt{30} }{39 - 8 \sqrt{30} } [/tex]

c. They are all in 1st quadrant

Daniel and his family are going on a summer vacation for 6 weeks exactly. Daniel estimates that he will need 6 loaves of bread to feed him during this time. Calculate how much bread Daniel will actually need, and state whether you agree or disagree with Daniel's estimate based on this calculation.

Answers

Answer:

Daniel will need 9 loaves of bread (108 slices)

Step-by-step explanation:

Daniel eats 18 slices of bread a week.

2 slices per week day (2 x 5 = 10)

4 slices per weekend day (4 x 2 = 8)

10 + 8 = 18

he will be there 6 weeks

18 x 6 = 108.

There are 12 slices of bread per loaf.

108 divided by 12 = 9.

Therefore, he will need 9 loaves of bread.
