Answer:

[tex]2x^2-25x+63[/tex]

Step-by-step explanation:

You have to multiply both terms from the first one by both term in the second on, it'll look like this:

[tex](x-9)*(2x-7)=(x*2x)+(x*-7)+(-9*2x)+(-9*-7)\\(x-9)*(2x-7)=(2x^2)+(-7x)+(-18x)+(63)[/tex]

Once you combine like terms it'll be the final answer:

[tex](x-9)*(2x-7)=2x^2-25x+63[/tex]

Set of ordered pairs = { ( 0 , 2 ),  ( π / 2 , 0) ,  ( π , -2) , ( 2 π , 2)}

Step-by-step Explanation:

Given  y = 2 cos x

i) Let  x =0 ⇒ y = 2 cos (0) = 2

The ordered pair ( 0 , 2 )

ii) Let x = π / 2  ⇒ y = 2 cos (π/2) = 2(0) =0

The ordered pair ( π / 2 , 0)

iii) let x = π ⇒ y = 2 cos(π) = 2 (-1) = -2

The ordered pair ( π , -2)

iv)

let x = 2π ⇒ y = 2 cos(2π) = 2 (1) = 2

The ordered pair ( 2 π , 2)

Set of ordered pairs = { ( 0 , 2 ),  ( π / 2 , 0) ,  ( π , -2) , ( 2 π , 2)}

Answer: The correct answer is C

Answer:

The distance between park and museum is 12km.

Step-by-step explanation:

Given that the map shows 1cm represents 3km. In this question, the distance between park and museum is 4cm so in order to find the real-life distance, you have to multiply by 4 :

[tex]1cm = 3km[/tex]

[tex]4cm = 3km \times 4[/tex]

[tex]4cm = 12km[/tex]

Hence, the real-life distance between the park and the museum is [tex]12km[/tex].

What is the simplification?

Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Here given that,

Here is a map of a town.The map shows a centimetre ruler [tex]1[/tex] cm represents [tex]3[/tex] km.

In a map it is mentioned that [tex]1[/tex]cm which represents the [tex]3[/tex] km. So, the distance between park and museum is

[tex]1+3=4[/tex]cm

So for the real-life distance, we multiply by [tex]4[/tex]

then,

[tex]1cm=3km\\\\4cm=3(4)km\\\\4cm=12km[/tex]

Hence, the real-life distance between the park and the museum is [tex]12km[/tex].

Answer:

(–4, 1)  

Step-by-step explanation:

1. Calculate the slope of AB

m₁ = (y₂ - y₁)/(x₂ - x₁) = (-4 - 4)/(0 -(-2))= -8/2 = -4

2. Calculate the slope of the perpendicular line

m₂ = -m₁ = ¼

3. Calculate its y-intercept

Point Z, (0,2), is the y-intercept.

4. Write the equation for the line

Insert the values of m and b

y = ¼x + 2

5. Check the points

(a) (-4,1)

1 = ¼(-4)+ 2

1 = -1 + 2

1 = 1

TRUE

(b) (1,-2)

-2 = ¼(1) + 2

-2 = ¼ + 2

-2 = 2¼

FALSE

(c) (2,0)

Step-by-step explanation:

[tex]\sqrt{285}[/tex]

[tex]=16.8819430161[/tex]

Answer:

Step-by-step explanation:

The geometric mean has a set up it must follow in order to "work". If you look at #3, x is a side of the smaller triangle that has a base of 3, but it's also a side of the large triangle that has a base of 3 + 8 which is 11.  That means that x is your geometric mean. Setting up the geometric mean will look like this:

[tex]\frac{3}{x}=\frac{x}{11}[/tex]

where x is the geometric means and the 3 and the 11 (the positions they are in) are the geometric extremes.

Now we cross multiply to solve for x:

[tex]x^2=33[/tex] and

[tex]x=\sqrt{33}[/tex]

That's the length of x in #3.

For #4, x is the side of the small triangle with the base of 7 and it's also the side of the large triangle with the base of 7 + 13 which 20. That means that x is the geometric mean. Setting up like above:

[tex]\frac{7}{x}=\frac{x}{20}[/tex] and

[tex]x^2=140[/tex] so

[tex]x=\sqrt{140}[/tex]

Answer:

40

Step-by-step explanation:

The number of gift baskets Nikki can make varies directly with the amount of time she spends making the baskets .

Let n be the number of baskets and let t be the mount of time it takes to make the basket. This means that:

n α t

=> n = kt

where k = constant of proportionality

She can make 4 baskets in every 1/2 hour.

This means that:

4 = k * 1/2

=> k = 4 * 2 = 8 baskets per hour

The time is now 5 hours (t = 5). Therefore:

n = 8 * 5 = 40 baskets

She can make 40 baskets in 5 hours.

Answer:

12 sec

Step-by-step explanation:

After 1 sec distance between the deer and the bear = (8 + 5) = 13 feet.

After x sec distance is 13x.

13x = 156

x= 156/13=12 sec

Answer:

36

Step-by-step explanation:

First we will add the bear and the deer's speed. 8+5=13. now we will divide by the distance, but the speed is in feet not yards, so multiply 156 by 13=468/ then do 13x=468 so x is equal to 36.

Answer:

v = -1

Step-by-step explanation:

First, you will need to solve it step-by-step:

(4v − 9)(1 + v) = 0

Next, you need to simplify both sides of the equation:

4v(2) − 5v − 9 = 0

Now, factor the left side of equation:

(4v − 9)(v + 1) = 0

The last thing you need to do is to set all of the factors to equal to zero:

4v − 9 = 0 or v + 1 = 0

So, that means that you answer:

v=9/4 or in your case, v = −1

Answer:

[tex]x=\frac{4}{3}[/tex]

Answer:

198.5 cm²

Step-by-step explanation:

The figure is composed of a central rectangle and 2 congruent semi- circular ends, equivalent to 1 circle with diameter = 10 cm, thus radius of 5 cm

length of rectangle = 22 - 5 - 5 = 12 cm, thus

area of rectangle = 10 × 12 = 120 cm²

area of circle = πr² = π × 5² = 25π ≈ 78.5 cm² ( to 1 dec. place )

Total area = 120 + 78.5 = 198.5 cm²

Answer:

30° and 110°

55° and 85°

70° and 70°

Step-by-step explanation:

Given that:

[tex]\angle B = 90^\circ[/tex]

To find the possible values for the other two angles [tex]\angle A\ and\ \angle C[/tex].

Property of a triangle is that the sum of all three angles is always equal to [tex]180^\circ[/tex].

OR

[tex]\angle A +\angle B +\angle C = 180^\circ\\\Rightarrow \angle A + 40^\circ + \angle C = 180^\circ\\\Rightarrow \angle A + \angle C = 180^\circ - 40^\circ\\\Rightarrow \angle A + \angle C = 140^\circ[/tex]

So, the sum of [tex]\angle A\ and\ \angle C[/tex] should be [tex]140^\circ[/tex]. We can select our answers according to this condition.

Option 1: 20° and 30°: the sum is [tex]50^\circ \neq 140^\circ[/tex] hence, not correct.

Option 2: 30° and 110°: the sum is [tex]140^\circ[/tex] hence, correct.

Option 3: 55° and 85°: the sum is [tex]140^\circ[/tex] hence, correct.

Option 4: 60° and 90°: the sum is [tex]150^\circ \neq 140^\circ[/tex] hence, not correct.

Option 5: 70° and 70°: the sum is [tex]140^\circ[/tex] hence, correct.

Hence, the possible answers can be:

30° and 110°

55° and 85°

70° and 70°

Answer:

30º and 110º

55º and 85º

There are two rectangles.

1= 8 x 4 = 32

2= 2x6 = 12

Total = 32 + 12 = 44 square km

Answer:

44 sq. KM

Step-by-step explanation:

To find the total area, we have to add the area's of each rectangle. For the bigger rectangle, we will go base times height.

[tex](8)(4)=32[/tex]

For the smaller rectangle, the width is 2 and height is 6 so we will multiply those.

[tex](2)(6)=12[/tex]

Now we have to add the two areas to get the grand area.
