Step-by-step explanation:

The length of arc KNJ is the circumference of the entire circle minus the measure of the 48 degree arc.

This means the central angle of this sector KNJ is 360-48=312.

Using the arc length formula, we get the arc length is (2)(pi)(16)(312/360)=416pi/15.

[tex]\rightarrow \sf 8\sqrt[3]{2}[/tex]

explanation:

[tex]\rightarrow \sf \sqrt[3]{x^{10}}[/tex]

insert -2 as x

[tex]\rightarrow \sf \sqrt[3]{(-2)^{10}}[/tex]

simplify

[tex]\rightarrow \sf \sqrt[3]{1024}}[/tex]

breakdown

[tex]\rightarrow \sf \sqrt[3]{2 * 8^3}}[/tex]

final answer

[tex]\rightarrow \sf 8\sqrt[3]{2}[/tex]

→ This a = 8 and b = 2

Answer:

[tex]8\sqrt[3]{2}[/tex]

Therefore, a = 8 and b = 2

Step-by-step explanation:

Substitute [tex]x=-2[/tex] into the expression:

[tex]\implies \sqrt[3]{(-2)^{10}}[/tex]

Apply exponent rule [tex](-a)^n=a^n[/tex] if n is even:

[tex]\implies \sqrt[3]{2^{10}}[/tex]

Apply exponent rule  [tex]a^{b+c}=a^b \cdot a^c[/tex]

[tex]\implies \sqrt[3]{2^9\cdot2^1}[/tex]

Apply radical rule  [tex]\sqrt[n]{ab} =\sqrt[n]{a} \sqrt[n]{b}[/tex]

[tex]\implies \sqrt[3]{2^9}\sqrt[3]{2}[/tex]

Apply radical rule  [tex]\sqrt[n]{a^m} =a^{\frac{m}{n}}[/tex]

[tex]\implies 2^{\frac{9}{3}}\sqrt[3]{2}[/tex]

Simplify:

[tex]\implies 2^3\sqrt[3]{2}[/tex]

[tex]\implies 8\sqrt[3]{2}[/tex]

Therefore, a = 8 and b = 2

Answer: 6

Step-by-step explanation:

3 divide 1/2=3x2/1

3x 2/1=6

Answer:

Part 1

Multiply both sides by 2π

2πf = √(g/L)

Square both sides

4π²f²= g/L

Invert both sides

1/(4π²f²) = L/g

Multiply both side by g

g/(4π²f²) = L

We usually write an equation with the subject (L) n the left

L = g/(4π²f²)

________________________

Part 2

Using the above equation with the given values:

L = g/(4π²f²)

. .= 9.8 / (4π² x 1.6²)

. .= 0.097m (= 9.7cm)

________________________

By the way, where it says

“f=1.6 then there are 2 beats a second, or 192 beats per minute (bpm).”

this should say

“f=1.6 then there are 3.2 beats a second, or 192 beats per minute (bpm)”

Step-by-step explanation:

The values are L = g/(4π²f²) and L.= 0.097m (= 9.7cm)

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

Here, we have,

Part 1

Multiply both sides by 2π

2πf = √(g/L)

Square both sides

4π²f²= g/L

Invert both sides

1/(4π²f²) = L/g

Multiply both side by g

g/(4π²f²) = L

We usually write an equation with the subject (L) n the left

L = g/(4π²f²)

________________________

Part 2

Using the above equation with the given values:

L = g/(4π²f²)

L.= 9.8 / (4π² x 1.6²)

L.= 0.097m (= 9.7cm)

Hence, The values are L = g/(4π²f²) and L.= 0.097m (= 9.7cm).

Answer:

Step-by-step explanation:

Assume the deep end has a larger volume, the difference in volume between the deep end and shallow end is:

Volume of the deep end - Volume of the shallow end

= (2x^2 + 12x + 10) - (4x^2 - 100)

= (2x^2 - 4x^2) + 12x + 10 + 100

= -2x^2 + 12x + 110 ft^3

Lets subtract

[tex]\\ \tt\Rrightarrow 2x^2+12x+10-(4x^2-100)[/tex]

[tex]\\ \tt\Rrightarrow 2x^2+12x+10-4x^2+100[/tex]

[tex]\\ \tt\Rrightarrow 2x^2-4x^2+12x+10+100[/tex]

[tex]\\ \tt\Rrightarrow -2x^2+12x+110ft^2[/tex]

Answer:

The converse is:

if the ratio of lefties to righties is 1 : 8, then for every 3 left handed people, there are 24 right handed people.

The truth value is:

True

Step-by-step explanation:

The statement can be split into:

p -> If a class has 3 left-handed people and 24 right-handed people,

q -> the ratio of lefties to righties is 1:8

The converse of a conditional statement is:

if q then p

So, we have the converse to be;

if the ratio of lefties to righties is 1 : 8, then for every 3 left handed people, there are 24 right handed people.

The truth value.

For p, we have.

Ratio = 3 : 24

This can be simplified to.

Ratio = 1 : 8

For q, we have:

Ratio = 1 : 8

Since both are true, then the truth value is true

As it emerges from the cross multiplication performed, the statement is correct.

Since it is stated that "If a class has 3 left-handed people and 24 right-handed people, then the ratio of lefties to righties is 1: 8", to determine if this statement is correct the following calculation must be performed:

Therefore, as it emerges from the cross multiplication performed, the statement is correct.

Answer:

see below

Step-by-step explanation:

Since the triangles are congruent

<A = <X

< B = < Y

<C = < Z

That means B = Y =  90

And C = Z = 37

The sum of the angles of a triangle are 180

A+ B+ C = 180

A + 90+37 = 180

A +127 = 180

A = 180-127

A =53

A = X = 53

We also know

AB = XY

BC = YZ

AC = XZ

AB = 3  so XY =3

YZ = 4  so BC =4

XZ = 5  so AC = 5

Answer:

s=144

t=36

Step-by-step explanation:

you minus 180 from 36 and you get 144 for s

then you minus 180 from 144 to get t

Answer:

t = 36°

s = 108°

Step-by-step explanation:

FE and DE are congruent. This means that triangle ΔDEF is isosceles.

Base angles (∠EFD and ∠EDF) in isosceles triangles are congurent.

∠EFD is 36°. This means that ∠t is also 36°

The measure of all the angles in a triangle is 180°

[tex]36+36+x=180\\72+x=180\\x=108[/tex]

∠s = 108°
