160​

Answers

Answer:

Step-by-step explanation:

Rational numbers:

(150+160)/2 = 310/2 = 155

(150+155)/2 = 305/2= 152.5

(155 +160)/2 = 315/2= 157.5

155, 152.5 , 157.5 are rational numbers between 150 and 160

Irrational numbers:

Irrational numbers are numbers that are non terminating and non repeating numbers

155.502003000.....

155.202002000......

156.3120578.......

Answer:

Required Answer :-

1st rational number

= a + b/2

= 150 + 160/2

= 310/2 (1)

2nd rational number

Middle term of 150 and 160 is 155

= 150 + 155/2

= 305/2

3rd rational number

= 160 + 155/2

= 315/2

write a quadratic function in the given form whose graph satisfies the given condition.
passes through (-4, 0), (2, 0), & (6, -20) in intercept form.
pls dont just steal points away...i rly need help with this...can you provide work to if not thats ok

Answers

Answer:

[tex]\displaystyle y=-\frac{1}{2}(x+4)(x-2)[/tex]

Step-by-step explanation:

We want to find a quadratic that passes through the points:

[tex](-4, 0), \, (2, 0), \text{ and } (6, -20)[/tex]

In intercept form.

First, note that the first two given points are the x-intercepts of our quadratic. Intercept or factored form is given by:

[tex]y=a(x-p)(x-q)[/tex]

Where p and q are the x-intercepts, and a is the leading coefficient.

So, we will substitute -4 and 2 for p and q:

[tex]y=a(x-(-4))(x-(2))[/tex]

Simplify:

[tex]y=a(x+4)(x-2)[/tex]

Next, the third point (6, -20) tells us that y = -20 when x = 6. So:

[tex](-20)=a(6+4)(6-2)[/tex]

Solve for a:

[tex]-20=10(4)a\Rightarrow 40a=-20[/tex]

Thus:

[tex]\displaystyle a=\frac{-20}{40}=-\frac{1}{2}[/tex]

Hence, our equation in intercept from is:

[tex]\displaystyle y=-\frac{1}{2}(x+4)(x-2)[/tex]

Each exterior angle of a regular decagon has a measure of (3x + 6)°. What is the value of x? x = 8 x = 10 x = 13 x = 18

Answers

Answer:

x = 10

Step-by-step explanation:

Each exterior angle of a regular decagon has a measure of (3x + 6)°. What is the value of x?

The sum of the exterior angles of a decagon = 360°

Decagon = 10 sides

Each angle in a decagon = 360/10

= 36°

We are told that:

Each exterior angle of a regular decagon has a measure of (3x + 6)°.

Hence,

(3x + 6)° = 36°

Collect like terms

3x = 36 - 6

3x = 30

x = 30/3

x = 10

Find the volume of the sphere. Either enter an exact answer in terms of π πpi or use 3.14 3.143, point, 14 for π πpi and round your final answer to the nearest hundredth.
radius is 8

Answers

Answer:

Solution :-

Volume of sphere = 4/3 πr³

Volume = 4/3 × 3.14 × 8³

Volume = 4/3 × 3.14 × 512

Volume = 4/3 × 1607.68

Volume = 2143 in³

[tex] \\ [/tex]

Given:-

Radius of the sphere is 8 units.

To Find:-

The volume of the sphere.

Solution:-

We know, volume of sphere is [tex] \frac{4}{3} [/tex]πr³

So, volume of sphere = [tex] \frac{4}{3} [/tex] × 3.14 × 8 × 8 × 8

= [tex] \frac{6430.72}{3} [/tex]

= 2143.6

The volume of the sphere is 2143.6 cubic units. [Answer]

Line BC is tangent to the circle centered at A. Find the measure of angle BCA. Explain or show your reasoning.

Answers

[tex] m\angle BCA= 33\degree[/tex]

Step-by-step explanation:

[tex] In\: \odot A[/tex] BC is tangent to the circle at point B.

Therefore, by tangent-radius theorem:

[tex] \therefore AB\perp BC[/tex]

[tex] \therefore \angle ABC = 90\degree [/tex]

[tex] In\: \triangle ABC, [/tex]

[tex] m\angle ABC +m\angle BAC +m\angle BCA= 180\degree [/tex]

[tex] 90\degree+57\degree +m\angle BCA= 180\degree [/tex]

[tex] 147\degree +m\angle BCA= 180\degree [/tex]

[tex] m\angle BCA= 180\degree - 147\degree[/tex]

[tex] m\angle BCA= 33\degree[/tex]

Why has it been difficult to pass laws regarding transportation? Like Minnesota, Virginia has also faced difficulties in how to budget the money for transportation. Improving transportation seems to be causing the General Assembly much debate. Should Virginia impose more taxes to meet the transportation needs of the state? Governor Timothy M. Kaine believes they should. He is asking the legislature for a $1 billion increase in taxes to do just this. While hes not pushing PRTs in his state, he has ambitious goals to improve roads and bridges, eliminate congestion, and expand hurricane escape routes.Unfortunately, the track record for this kind of tax increase is not a good one. Since 2003, Virginia has denied 62 bills for a sales tax increase, eight bills to raise the car sales tax, and two attempts to increase grantors tax on home sellers. Other tax increases initiated by legislators in Virginia have not been successful either. The attempt to raise the gas tax has been rejected 31 times since 2003, and the eight bills to raise the recordation tax paid when a new home is being built have been turned down as well. The GOP leaders adamantly oppose these new taxes, and most of these bills have died in the House of Delegates.a.it would cause too much of a tax increasec.they dont have enough money to fund itb.people disagree on whether or not there should be PRTsd.budgeting the transportation allocated fundsPlease select the best answer from the choices providedABCD What is the area of the parallelogram?4 cmi5 cm9 cm18 cm228 cm?36 cm20 45 cm2 CDWho painted the portrait above?
