Step-by-step explanation:

[tex]\begin{aligned} &\sf (x+6)(x-8) \\=&\sf x^2-8x+6x-48 \\=&\boxed{\sf x^2-2x-48} \end{aligned}[/tex]

Answer:

Step-by-step explanation: Exponential depreciation formula :-

y = A(1 - r)^t, where y is the value of good after t years , r is rate of depreciation and A is the initial value.

Given : A= $20800  ; r=10.75%=0.1075  

The equation models this situation:

Then, the value of car after t=13 years :-

Hence, the value of car after 13 years = $4742.10

Answer:

Done

Step-by-step explanation:

Teacher bought $21 worth of stickers and cardstock for his class.

Cost of stickers = $1.50 per sheet

Cost of 's' sheets = $1.5s

Cost of cardstock = $3.50 per pack

Cost of 'c' packs = $3.5c

Equation representing the relationship between sheet of stickers and packs of cardstocks will be,

1.5s + 3.5c = 21

3.5c = -1.5s + 21

1).  

  y-intercept of the line → (0, 6)

  x-intercept of the line → (14, 0)

  Therefore, equation of the line represents the line on the graph.

2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.

  Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.

Sum.of two interiors=Exterior

Answer:

a) 1/2

b) 250

Step-by-step explanation:

The start of the question doesn't matter entirely, although is interesting to read. What we are trying to do is find the value for [tex]p[/tex] such that [tex]1000p(1-p)[/tex] is maximized. Once we have that [tex]p[/tex], we can easily find the answer to part b.

Finding the value that maximizes [tex]1000p(1-p)[/tex] is the same as finding the value that maximizes [tex]p(1-p)[/tex], just on a smaller scale. So, we really want to maximize [tex]p(1-p)[/tex]. To do this, we will do a trick called completing the square.

[tex]p(1-p)=p-p^2=-p^2+p=-(p^2-p)=-(p^2-p+1/4)-(-1/4)=-(p-1/2)^2+1/4[/tex].

Because there is a negative sign in front of the big squared term, combined with the fact that a square is always positive, means we need to find the value of [tex]p[/tex] such that the inner part of the square term is equal to [tex]0[/tex].

[tex]p-1/2=0\\p=1/2[/tex].

So, the answer to part a is [tex]\boxed{1/2}[/tex].

We can then plug [tex]1/2[/tex] into the equation for p to find the answer to part b.

[tex]1000(1/2)(1-1/2)=1000(1/2)(1/2)=1000*1/4=250[/tex].

So, the answer to part b is [tex]\boxed{250}[/tex].

And we're done!

Answer:

10% is the answer to this question

Answer:

the values are x= 0.94 and x= -3.19

 Answer:

In order to compare the fractions we can first obtain the LCM of the denominators of the two fractions and that is to say

= LCM of 5 and 3 which is 15

= [tex]\frac{2}{5} * 15[/tex]

=6

and also:

= [tex]\frac{1}{3} * 15[/tex]

=5

So in conclusion the numbers 6 and 5 will determine the sign to be used and since 6 is for [tex]\frac{2}{5}[/tex] and 5 is for [tex]\frac{1}{3}[/tex] and numerically 6 is greater than 5 therefore:

[tex]\frac{2}{5} > \frac{1}{3}[/tex]

Answer:

43xx

Step-by-step explanation:

5x(2x+7)+x(3x-5)

first, do the equations inside the parentheses

2x+7=9x

3x-5=-2x

so,

5x(9x)+x(-2x)

Next, do 5x times 9x

(5x) x (9x) = 45

so,

45+x(-2x)

Next, do x times (-2x)

(x) x (-2x)=-2xx

so,

45+-2xx

=43xx

Answer:

- 5 [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

- 3 [tex]\frac{1}{2}[/tex] - 1 [tex]\frac{5}{6}[/tex] ( change to improper fractions )

= - [tex]\frac{7}{2}[/tex] - [tex]\frac{11}{6}[/tex] ( multiply numerator/denominator of first fraction by 3 )

= - [tex]\frac{7(3)}{2(3)}[/tex] - [tex]\frac{11}{6}[/tex]

= - [tex]\frac{21}{6}[/tex] - [tex]\frac{11}{6}[/tex]

= [tex]\frac{-21-11}{6}[/tex]

= [tex]\frac{-32}{6}[/tex]

= - [tex]\frac{32}{6}[/tex]

= - 5 [tex]\frac{2}{6}[/tex]

= - 5 [tex]\frac{1}{3}[/tex]

the reciprocal is 8/-9 just reverse the numbers

Answer:

3×10'-2 is larger

Step-by-step explanation:

2×10'-3=0.002

3×10'-2=0.03

Answer:

3x10^-2 is larger

Step-by-step explanation:

2x10^-3 = 0.002

beause 10^-3 = decimal place three place to the left

3x10^-2 = 0.03

beause 10^-2 = decimal place two place to the left

Answer:

12

Step-by-step explanation:

So, she practices 12 hrs per week, and already has practiced 3 hrs this week.

This means she has 9 hrs left to practice.

3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)

which is basically 9 / ( 3/4)

[tex]\frac{9}{3/4}=\frac{9}{1} / \frac{3}{4} = \frac{9}{1} * \frac{4}{3} = \frac{36}{3} = 12[/tex]

She needs 12 more sessions.

Answer: -7, 12

Step-by-step explanation:

a+b = 5

a*b = -84

a = 5-b

(5-b)*b = -84

-b^2 + 5b + 84 = 0

(-b - 7)(b + 12) = 0

The roots are -7 and 12.

Answer:

In a categorical variable, the value is limited and usually based on a particular finite group. For example, a categorical variable can be countries, year, gender, occupation. A continuous variable, however, can take any values, from integer to decimal.

Answer:

x=6

Step-by-step explanation:

5a) 5x-7=2x+18

5b) 6

5c) 23

5d) 30

Step-by-step explanation:

1.5x + 6-3= 4.5x- 2

1.5x+3=4.5x-2

we transposed

4.5x-1.5x= 3+2

3x= 5

we divide both sides by 3

3x/3= 5/3

x= 5/3
