Answer:

6x^2^x^2+x^4

Step-by-step explanation:

Answer:

Yes your answer is correct

Step-by-step explanation:

First of all you multiply 3x with 2x which equals 6x power 2 because we sum the power. Then we multiply 6x power 2 with x power 4 which equals 6x power 6 because X is 1X so the answer is 6X power 6

Answer:

167.467mm^3

Step-by-step explanation:

Volume of cone:1/3hpir^2

1/3(10)(pi)(4)^2

=160/3(pi)

(Pi=3.14)

160/3pi=167.467mm^3

Answer:

27

Step-by-step explanation:

25(0.08)=2+25=27

25(0.08)+25=27

Answer:

Step-by-step explanation:

From the question we are told that:

Initial bearing [tex]\angle _1=21 \textdegree[/tex]

Initial distance [tex]d_1=99miles[/tex]

Final bearing [tex]\angle _2=227 \textdegree[/tex]

Let [tex]\triangle OAB[/tex] be the perimeter travailed

[tex]\angle OAB=90+21=111 \textdegree\\\angle ABO=270-227=43 \textdegree[/tex]

Generally the equation for OB using sine rule is mathematically given by

[tex]OB=99*\frac{sin111}{sin43}[/tex]

[tex]OB=135.52miles[/tex]

Therefore the helicopter flight on the final leg of its​ journey is

[tex]OB=135.52miles[/tex]

Answer:

A. (125.6 in)

Step-by-step explanation:

R = d / 2 = 40 / 2 = 20 in

Circumference is:

S = 2*π*R=2*3.14*20=125.6 in

Answer:

D. 735.25 cubic inches.

Step-by-step explanation:

Well hello there! My name is Lunako, and I'm here to help you out.

Firstly, do you remember the formula for finding the volume of the sphere? Yep, it's 4π(r³/3)! I'll substitute r for 5.6 -- which is 11.2 divided by 2, but you knew that already right? -- and π for 3.14 -- I'm doing that for relative ease.

4(3.14) * (5.6³/3) {Firstly we need to need find the cube of 5.6. That would be 175.616. Let me show the work for that: 5.6 * 5.6 = 25 + 3 + 3 + 0.36 = 31.36; 31.36 * 5.6 = 150 + 5 + 1.5 + 0.3 + 18 + 0.6 + 0.18  + 0.036 = 155 + 1.8 + 18.6 + 0.216 = 156.8 + 18.816 = 175.616}

4(3.14) * (175.616/3) {Now divide 175.616 by 3 to get 58.5387 (rounded to 54 places).}

4(3.14) * 58.5387 {Now onto the left sides. 3.14 quadrupled is 12.56.}

12.56 * 58.5387 {Now for the last step: Multiplying 12.56 by 58.5387. The work for that is shown in the picture. You should get 735.246072.}

735.246072 in³ {While this is the answer, we need to round it to two decimal places, like in the answer choices. 6 is greater then 5, so round up to 735.25.}

735.25 in³ {And with that this problem is solved.}

The volume of the sphere is 735.25 cubic inches, which is D.

Answer:

600ft²

Step-by-step explanation:

Oh boy, this is gonna be a long one, so proceed with caution:

So we're gonna start with the one to the very left, we can split this into three different rectangles:

So we got the length of the bottom minus the length we don't want there because we're doing the big rectangle:

35 - 10 = 25

25 x 20 = 500

So we're just gonna keep that on a back burner, cause now we gotta do the two smaller ones:

So we got the measure from the one side, but we gotta subtract the 10 from the other side:

20 - 10 = 10

10 x 10 = 100

Now we gotta add that all up:

500 + 100 = 600

So the area of the first shape is 600ft²

I gotta go, but hope this helps a little bit

Answer:

The area of the trapezoid is 108 square feet

Step-by-step explanation:

The given vertices of the trapezoid are;

(-6, 9), (-6, 6), (3, -9, and (3, 12)

Let the letters A, B, C, and D represent the vertices of the trapezoid, we have;

A(-6, 9), B(-6, 6), C(3, -9) and D(3, 12)

The drawing of the trapezoid on the coordinate plane created with MS Excel is attached

The area of a trapezoid, [tex]A_T[/tex] = (a + b)×h/2

Where;

'a', and 'b' = The length of the bases (parallel sides)

h = The height of the trapezoid (The distance between the bases)

Let 'a' represent the length of the long base CD and let 'b' represent the length of the short base AB

a = √((-9 - 12)² + (3 - 3)²) = 21

∴ a = 21 feet

Similarly, we have;

b = √((9 - 6)² + (-6 - (-6))² = 3

The height, h = The distance between AB and CD = AE

We note that sides AB and CD are parallel to the y-axis, therefore, the height which is the perpendicular distance to the between AB and CD will be parallel to the x-axis

Therefore, the t-coordinates of the points A and E are both equal to 9 and the length of AE = √((3 - (-6))² + (9 - 9)²) = 9

The height of the trapezoid, AE = 9 feet

∴ The area of the trapezoid, A = (21 + 3) × 9/2 = 108

The area of the trapezoid, [tex]A_T[/tex] = 108 ft.²

Answer:

$45.05

Step-by-step explanation:

Sale price of sweater is (1.00 - 0.15)($50), or 0.85($50) = $42.50.  Nya has to pay 6% sales tax on this $42.50.  Thus, the final amount due is

(1.00 + 0.06)($2.50) = $45.05

Answer:

46.42

Step-by-step explanation:

First step is to find the discount

Discount = original price * discount rate

= 55 * 20%

= 55*.20

=11

Take the discount from the original price and that is the new price

new price = original price - discount

= 55-11

=44

Now we need to find the tax

tax = new price * tax rate

= 44 * 5.5%

= 44 * .055

=2.42

The final price is the new price plus the tax

final price = new price + tax

= 44+2.42

=46.42

Therefore, Nya will pay $46.42 for the sweater if she buys it.

Answer:

(11/2)² or 121/4 would be added to the equation x ² +11x+30=0,  to "complete the square".

Step-by-step explanation:

x 2 +11x+30=0

Write the equation in the form of the square

(x)^2 + 2(x) (11/2)  + (11/2)^2  + 30 - 121/4= 0

Square of the first element + 2 into first element into 2nd element + square of 2nd element gives the complete square formula.

How we obtained the second element?

The mid term broken must always be equal to the mid term given.

Hence

2(x)    can only be equal to 11x if we multiply it by 11 and divide it with 2.

So the second term must be 11/2 .

To complete the square this second term ( 11/2)² is added and then subtracted to keep the equation equal to the original equation.

(x)^2 + 2(x) (11/2)  + (11/2)^2  + 30 - 121/4= 0

Putting it in the form of square

(x+ 11/2)^2  + 120-121/4= 0

Taking LCM and solving

(x+ 11/2)^2   - 1/4= 0

(x+ 11/2)^2  = 1/4

Taking square root on both sides

(x+ 11/2)   = ± 1/2

x= - 11/2  ± 1/2

x= -10/2= -5

x= -12/2= -6
