Answer:

True

Step-by-step explanation:

This is Converse Isosceles property theorem.

It states that if two angles of a a triangle are congruent, then the sides opposite to those angles are congruent

Step-by-step explanation:

The given expression is:

[tex]r=\dfrac{2p^2}{q-3}[/tex]

We need to solve it to make q the subject of the formula.

Cross multiplying both sides,

[tex]rq-3r=2p^2[/tex]

Adding 3r to both sides,

[tex]rq-3r+3r=2p^2+3r\\\\rq=2p^2+3r[/tex]

Now, dividing both sides by r,

[tex]q=\dfrac{2p^2+3r}{r}[/tex]

Hence, this is the required solution.

Pythagoras theorem states that for a right angle triangle the measure of the  square of the hypotenuse side is equal to the sum of the square of the other two sides.The ladder has to be kept at 13.3( round to the nearest tenth) feet away from the bottom of the wall.

Given information-

The length of the ladder is 24 foot.

The height of the wall is 20 foot.

Suppose the ladder has to kept at x feet away from the bottom of the wall

Here a right angle is formed in which the ladder is hypotenuse side shown in the diagram attached below.

Pythagoras theorem states that for a right angle triangle the measure of the  square of the hypotenuse side is equal to the sum of the square of the other two sides.

As the ladder has to be kept at x feet away from the bottom of the wall. Thus,

[tex]24^2=20^2+x^2\\ 576=400+x^2[/tex]

Solve for the x,

[tex]x=\sqrt{576-400}\\ x=\sqrt{176}\\ x=13.266[/tex]

hence the ladder ladder has to be kept at 13.3( round to the nearest tenth) feet away from the bottom of the wall.

Answer:

Option A is the correct answer, since it is the closest answer.

Step-by-step explanation:

volume: V = 4/3 πr³

Try replacing r with half number of the options

A) 4/3 x π x 8.3 ^3 = 2395.09

B) 4/3 x π x 5.05 ^3 = 539.46

C) 4/3 x π x 4.15 ^3 = 299.38

D) 4/3 x π x 2.1 ^3 = 38.79

The g(x) is equal to (2/3)x.To find g(x) in the composite function h(x) = f(g(x)), we need to substitute f(x) = 2x - 1 into the equation and solve for g(x

Given that h(x) = (4/3)x - 1 and f(x) = 2x - 1, we can set up the composite unction:

h(x) = f(g(x))

Substituting f(x) into the equation:

(4/3)x - 1 = 2(g(x)) - 1

Simplifying the equation:

(4/3)x - 1 = 2g(x) - 1

We can now solve for g(x):

2g(x) = (4/3)x

Dividing both sides by 2:

g(x) = (2/3)x

Answer:

  B.  6.7

Step-by-step explanation:

The triangles are similar, so corresponding sides have the same ratio.

Answer:

c=13.6km, B=47.9⁰, A=22.8⁰,

Using the cosine rule, the missing parts of the triangle are:

c = 13.6 km; B = 47.9°; C = 22.8°

Cosine rule is given as, c² = a² + b² ﹣ 2ab(cosC)

Given the following:

Find c using the cosine rule:

c² = 5.6² + 10.7² ﹣ 2(5.6)(10.7)(cos 109.3)

c² = 185.5

c = √185.5

c = 13.6 km.

Use the cosine rule to find A:

5.6² = 10.7² + 13.6² ﹣ 2(10.7)(13.6)(cosA)

31.36 = 299.45 ﹣ 291.04(cosA)

31.36 - 299.45 = ﹣ 291.04(cosA)

-268.09 = ﹣ 291.04(cosA)

0.9211 = (cosA)

C = cos^(-1)(0.9211)

C = 22.8°

Find B:

B = 180 - 22.8 - 109.3

B = 47.9°

Therefore, using the cosine rule, the missing parts of the triangle are:

c = 13.6 km; B = 47.9°; C = 22.8°

Answer:

  5.5

Step-by-step explanation:

The rate of change is given by the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (16.5 -11)/(3 -2) = 5.5/1

  m = 5.5

The rate of change of this function is 5.5.

Answer:

The volume is increasing at a rate of 25,133 mm/s.

Step-by-step explanation:

Diameter is 40mm

Radius is half the diameter, so [tex]r = \frac{40}{2} = 20[/tex]

How fast is the volume increasing when the diameter is 40mm?

We have to apply implicit differentiation, of V and r in function of t. So

[tex]V = \frac{4}{3} \pi r^3[/tex]

[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]

The radius of a sphere is increasing at a rate of 5 mm/s.

This means that [tex]\frac{dr}{dt} = 5[/tex]

Then

[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]

[tex]\frac{dV}{dt} = 4\pi (20)^2(5)[/tex]

[tex]\frac{dV}{dt} = 25133[/tex]

The volume is increasing at a rate of 25,133 mm/s.

Answer: $2.46

Step-by-step explanation:

First, let's find the unit price for both buckets!

A 1 gallon bucket of paint is $21.95. But how much will a 1 gallon bucket of paint cost if it had origianlly been 97.45 for 5 gallons of paint?

We need to divide 97.45 by 5, and the answer will be the unit price.

97.45 ÷ 5 = 19.49.

A 1 gallon bucket of paint that was originally priced as $97.45 for 5 gallons of paint si now $19.49 per bucket.

But we're not done! We still need to find the difference in unit prince between a 5 gallon bucket of paint for $97.45 and a 1 gallon bucket of paint for $21.95.

21.95 - 19.49 = 2.46.

Therefore, the difference in unit price between a 5 gallon bucket of paint for $97.45 and a 1 gallon bucket of paint for $21.95 is $2.46.

That is what came out in my calculator. I don't know if you need it in decimal or in a solid integer but if you were to round 76.9 you would get 77, it is always good to check your work so,

77 times 13
