A, C and D are true statements.

Step-by-step explanation:

Megan constructed triangle ABC.

In Megan’s triangle, m∠A is represented by x°.

Therefore, ∠A = x°

For m∠B is 4 times greater than m∠A

Therefore, ∠B = 4x°

For m∠C is 30° less than 5 times m∠A.

Therefore, ∠C = 5x°-30°

ABC is a triangle.

Sum of all angles of a triangle is 180°. Angle sum property of triangle.

m∠A + m∠B + m∠C = 180°

x° + 4x° + 5x°-30° = 180°

x° = 15°

True Statements are:

A) m∠A = x°

C) m∠B = (4x)°

D) m∠C = (5x – 30)°

Find the slope of the tangent to the curve [tex]y=3+4 x^{2}-2 x^{3}[/tex] at the point where [tex]x=a\text{.}[/tex]

The derivative of a function can be determined using different rules and formulations. One of the important rules here is the power rule. Power rule is used to differentiate functions in the form of [tex]f(x) = x^n[/tex].

[tex]\; \dfrac{d}{dx} (x^n) = nx^{n-1}[/tex]

We are supposed to find the slope of the tangent to the curve [tex]y=3+4 x^{2}-2 x^{3}[/tex] at the point where [tex]x=a[/tex].

[tex]\implies \dfrac{d}{dx}(3+4x^2-2x^3)[/tex]

[tex]\implies \dfrac{d}{dx}(0+4(2x^{2-1})-2(3x^{3-1})[/tex]

[tex]\implies \dfrac{d}{dx}(0+4(2x)-2(3x^2)[/tex]

[tex]\implies \dfrac{d}{dx}(8x-6x^2[/tex]

Now plugging [tex]x=a[/tex] in the above equation, we obtain the following results:

[tex]\implies \boxed{8a -6a^2}[/tex]

Hence, this is our required solution for this question.

y = .78x

y = 108.5x

y = .946x

Answer:

Since x = 3, y = 1 is the solution of

x – 4y + p = 0 …………….. (i)

2x + y – q – 2 = 0 …………… (ii)

So, x = 3, y = 1 must satisfy both (i) and (ii).

⇒ 3 – 4(1) + p = 0 ⇒ p = 1.

and 2(3) + (1) – q – 2 = 0 ⇒ q = 5

Since, 1 = – 4 + 5

∴ p = 1 = – 4 + 5

= q – 4

⇒ p = q – 4

Answer:

1/6 or 0.167

Step-by-step explanation:

First understand that 4 x 1/4 is equal to 1, then replace it in the equation

1 - 5/6

Turn the whole number into a fraction that can be computed

6/6 - 5/6

Solve the equation

6/6 - 5/6 = 1/6

If you need it as a decimal enter it in a calculator and get

0.16666666667

Since the 6 is repeating you can just round that to

0.167

Step-by-step explanation:

1) The area of rectangle is ( 30x²y + 20xy ) cm² and its breadth is 10xy cm .Find its length....

= Solution ,

Length ( L ) = ?

breadth ( b ) = 10xy cm

area ( a ) = ( 30x² + 20xy )

Now ,

area ( a ) = l × b

or, ( 30x²y + 20xy ) = L × 10xy cm

[tex]or,\frac{30 {xy + 20xy}^{2} }{10xy} = l \\ [/tex]

[tex]or, \: l = 3 {x}^{2 - 1} + 2cm[/tex]

[tex]\boxed{\sf{l = (3x+2)cm}}[/tex]

2) Subtract the quotient when 20x⁴y² is divided by 5x³y from the product of 2x and 3y.

= Solution,

[tex] = \frac{20 {x}^{4} {y}^{2} }{5 {x}^{3} y} \\ [/tex]

[tex] = 4xy[/tex]

The product of 3x and 4y = 6xy

= 6x - 4xy

[tex] = \boxed{\sf {2xy}}[/tex]

The mass of 2 bags, which is filled by Lynn each with 2 kilograms 450 grams of sand, is less than 5 kilograms.

Weight measurement is the measurement of the heaviness of a object. The units of weight measurement are pounds, grams, kilograms etc.

There is total 1000 grams in one kilogram of weight measurement.

Lynn filled each of three bags with 2 kilograms, 450 grams of sand. There is total 1000 grams in one kilogram of weight measurement. Thus, the kilogram in 450 grams is,

[tex]x=\dfrac{450}{1000}\\x=0.45\rm\; kg[/tex]

Thus, weight in one bag is,

[tex]W=2+0.45\\W=2.45\rm\; kg[/tex]

The weight in two bags is,

[tex]2W=2.45+2.45\\2W=4.9\rm\; kg[/tex]

The weight of 4.9 kg is less than the 5 kilogram..

Thus, the mass of 2 bags, which is filled by Lynn each with 2 kilograms 450 grams of sand, is less than 5 kilograms.

Answer:

cos B = 9/41

tan B = 40/9

sin B = 40/41

Step-by-step explanation:

There is no picture, so I am making a few assumptions.

I am assuming that angle C is the right angle and is opposite 41.

I am also assuming that angle B is formed by the sides that measure 9 and 41. The hypotenuse is 41.

For angle B, the adjacent leg is 9, and the opposite leg is 40.

cos B = adj/hyp = 9/41

tan B = opp/adj = 40/9

sin B = opp/hyp = 40/41

Answer:

This is the answer I understood and got.

B. Yes. There is a constant of proportionality of $4.50.

Step-by-step explanation:

When you divided 9/2, you get 4.5

When you divide 22.5/5, you get 4.5

When you divide 31.5/7, you get 4.5
