Answer:

[tex] \huge{ \boxed{ \tt{1 }}}[/tex]

❁ Question : Simplify :

[tex] \sf{( {x}^{a} ) ^{b - c} \times ( {x}^{b} ) ^{c - a} \times ( {x}^{c} )^{a - b}} [/tex]

❁ Solution :

First , Use power law of indices.

Remember : If [tex] \sf{ {a}^{m} }[/tex] is an algebraic term , then

[tex] \sf{( {a}^{m} ) ^{n} } = {a}^{m \times n} = {a}^{mn} [/tex] , where m and n are positive integers.

➝ [tex] \sf{ {x}^{a(b - c)} \times {x}^{b(c - a)} \times {x}^{c(a - b)}} [/tex]

➝ [tex] \sf{ {x}^{ab - ac} \times {x}^{bc - ba} \times {x}^{ca - cb}} [/tex]

Now , Use product law of indices :

Remember : If [tex] \sf{ {a}^{m} }[/tex] and [tex] \sf{ {a}^{n}} [/tex] are the two algebraic terms , where m and n are the positive integers then [tex] \sf{ {a}^{m} \times {a}^{n} = {a}^{m + n}} [/tex]

➝ [tex] \sf{ {x}^{ab - ac + bc - ba + ca - cb}} [/tex]

Since two opposites adds up to zero , remove them :

➝ [tex] \sf{ {x} \: ^{ \cancel{ab} \: - \cancel{ac} \: + \cancel{bc} \: - \cancel{ba} \: + \cancel{ca} \: - \cancel{cb} } }[/tex]

➝ [tex] \sf{ {x}^{0} }[/tex]

Use Law of zero index

Remember : If [tex] \sf{ {a}^{0}} [/tex] is an algebraic term , where a ≠ 0 , then [tex] \sf{ {a}^{0} = 1}[/tex]

➝ [tex] \boxed{ \sf{1}}[/tex]

And we're done !

Hope I helped ! ♡

The ratio of the Jen height to Jen's shadow heightis 5'6'' : 9' which is equal to 66in.:108in.

To find the ratio we do 108/66 = 1.636...

Then we do 80' which is equal to 960"

Lastly we do 960/1.636... to get 586.797in for the height of the tree

The blues band, Jonny and the Silver Toads, charges $25 per ticket at their performances. Their next venue charges them $900 for use of the venue. Based on the inequality below, how many tickets, , do they need to sell in order to profit at least $1,925?

Answers

Answer:

The band must sell at least 113 tickets to make a net profit of at least $ 1,925.

Step-by-step explanation:

While the band charges $ 25 for each entrance ticket to their performances, and the venue charges them $ 900 for the use of the place, the number of tickets that must be sold for the band to obtain a profit of at least $ 1,925 arises from the following calculation:

1,925 + 900 = Costs plus profit

2,825 / 25 = Number of tickets needed to cover costs and profit

113 = Number of tickets needed to cover costs and profit.

Therefore, the band must sell at least 113 tickets to make a net profit of at least $ 1,925.

3u – 5(v + w)

3⟨9, –2⟩ – 5[⟨–4, 3⟩ + ⟨5, 1⟩]

⟨32, –26⟩

What mistake did Kelcy make?

Answers

Answer:

She added incorrectly

Step-by-step explanation:

Answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead of taking 1 because -4 +5 is 1.

What are Vectors?

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction.

Let  u = ⟨9, –2⟩, v = ⟨–4, 3⟩, and w = ⟨5, 1⟩

3u – 5(v + w)

3(9, -2)-5(⟨–4, 3⟩+⟨5, 1⟩)

Multiply 3 to (9, -2) and add v and w

(27,-6)-5(1,4)

(27, -6)-(5, 20)

Subtract the vectors

(27-5, -6-20)

(22, -26)

The answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead f taking 1 because -4 +5 is 1.

Hence,  answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead f taking 1 because -4 +5 is 1.

Kendra and Dalisay practice archery, Kendra hits the target 3 times for
every 5 misses Dalisay hits the target 5 times for every 7 misses.
Who hits the target more?

Answers

Answer:

Dalisay

Step-by-step explanation:

3/5=0.6 (Kendra)

5/7≈ 0.75 (Dalisay)

5/7>3/5, so Dalisay hits the target more.

The probability of Dalisay hitting the target is more.

What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

According to the given problem,

Kendra hits target 3 times for 5 misses

Probability = [tex]\frac{3}{5}[/tex]

                  = 0.6

Dalisay hits target 5 times for every 7 misses

Probability = [tex]\frac{5}{7}[/tex]

                  = 0.71

Hence, we can conclude that Dalisay hits the target more.

Answer:

Step-by-step explanation:

y + 3x  =  180    {Co interior angles}

        y = 180 - 3x    ------------(I)

7x + 20 = y       {Vertically opposite angles}

7x + 20 = 180 - 3x   {From equation (I)}

7x + 3x +20 = 180

       10x + 20 = 180

            10x  = 180 -20

              10x = 160

                 x = 160/10

                x = 16

Plug in x = 16 in equation (I)

y = 180 - 3x

What is the solution?

Answers

Answer:

7x - 3y = -12

Step-by-step explanation:

5(0-1) + 3y = 7(x + 1)

using BODMAS to solve

5(-1) + 3y = 7(x + 1)

-5 + 3y = 7x + 7

7x - 3y = -5 - 7

7x - 3y = -12

Write an equation in point-slope form of the line that passes through the given point and has the given slope. (5,-4); m = -1

Answers

Answer:

y + 4 = - (x - 5)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 1 and (a, b) = (5, - 4) , then

y - (- 4) = - 1 (x - 5) , that is

y + 4 = - (x - 5)

Answer:

[tex]y+4=-(x-5)[/tex]

Step-by-step explanation:

Point-slope form equation is written as:

[tex]y-y_1=m(x-x_1)[/tex]

where m is the slope and [tex](x_1,y_1)[/tex] is the point which the line passes through  so to to find the equation of line which passes through the point

(5 , -4) it means the point should satisfy the equation which furthermore means that the point lies on the lie so we can replace y1 with -4 and x1 with 5 and since we have m = -1 we can thus find b and rewrite the equation like this:

[tex]y-y_1=m(x-x1)\\y-(-4)=-1(x-5)\\y+4=-x+5[/tex]

since we need it point-slope form we leave it like this

[tex]y+4=-(x-5)[/tex]

Emma's grandmother sent her an $80 bookstore gift card for her birthday. Emma wants to make sure that her purchases don't exceed the amount of her gift card. So far, she has selected books that cost $8.95, $11.95, $22.25, and $24.95. She has also found a calendar she likes for $8.25. Round each item up to the next dollar to overestimate the total cost of the items in Emma's shopping basket.

Answers

Answer: total cost of the estimated  items = $76

Step-by-step explanation:

 Step 1

Rounding up each item to the next dollar

Book 1 = $8.95 ≈ $9.00

Book 2 = $11.95≈ $12.00

Book 3 = $22.25≈$22.00

Book 4 =   $24.95≈$25.00

Calendar = $8.25 ≈$8.00

Step 2

The total estimated cost of items in Emma's shopping basket =$9.00+$12.00+$22.00+$25.00+$8.00

=$76  which did not exceed the amount of bookstore gift card of $80 sent by her grandmother.

Answer: 78$

Actual                            Estimate

$8.95 --------------------------$9.00

$11.95--------------------------$12.00

22.25--------------------------$23.00

$24.95------------------------$25.00

 $8.25--------------------------$9.00

Then add the estimate numbers to get $78

C) imaginary

D) real, rational, and equal

Answers

Answer:

D.

Step-by-step equation:

I don't know but i think this is the answer.

The roots of the equation are x = 0.5205 and x = -0.8538. These roots are real, rational and unequal, thus option (B) is the correct answer.

What is a quadratic equation?

A quadratic equation is a polynomial which has the highest degree equal to two. It is a second-degree equation of the form ax² + bx + c = 0, where a, b, are the coefficients, c is the constant term, and x is the variable.

For the given situation,

The equation is 9x^2 + 3x – 4 = 0

The roots of the equation can be found by the formula,

[tex]x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]x=\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]

here, a = 9, b = 3 and c = -4

Substitute the above values,

⇒ [tex]x=\frac{-3+\sqrt{3^{2}-4(9)(-4) } }{2(9)}[/tex] or  [tex]x=\frac{-3-\sqrt{3^{2}-4(9)(-4) } }{2(9)}[/tex]

⇒ [tex]x=\frac{-3+\sqrt{9+144 } }{18}[/tex]          or  [tex]x=\frac{-3-\sqrt{9+144 } }{18}[/tex]

⇒ [tex]x=\frac{-3+\sqrt{153 } }{18}[/tex]             or  [tex]x=\frac{-3-\sqrt{153 } }{18}[/tex]

⇒ [tex]x=\frac{-3+12.36 }{18}[/tex]             or  [tex]x=\frac{-3-12.36 }{18}[/tex]

⇒ [tex]x=\frac{9.37}{18}[/tex]                    or  [tex]x=\frac{-15.37}{18}[/tex]

⇒ [tex]x=0.5205[/tex]                or  [tex]x=-0.8538[/tex]

Hence we can conclude that the roots of the equation are x = 0.5205 and x = -0.8538. These roots are real, rational and unequal, thus option (B) is the correct answer.

Solving:

[tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex]

Convert mixed fraction into improper fraction

[tex]\frac{2}{5}K-\frac{7}{2}K =15[/tex]

[tex]\frac{2*2K-7*5K}{10} =15\\\frac{4K-35K}{10} =15\\\frac{-31K}{10} =15[/tex]

[tex]\frac{-31K}{10}*\frac{-10}{31}=15* \frac{-10}{31}\\K=\frac{-150}{31} \\K=-4\frac{26}{31}[/tex]

So, solving the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] we get [tex]\mathbf{K=\frac{-150}{31} \ or \ \ K=-4\frac{26}{31} }[/tex]
