Can someone help me with this? The teacher assigned this for homework even though we haven't learned about this yet...... it's about functions in math.

Here are the drop-down menu answer choices for "The domain of f is":
*the final exam scores
*the history classes in the school
*the students in Mr. Well's history class
*the real numbers

Here are the drop-down menu answer choices for "The range of f is":

*the real numbers

ALSO:
Please fill in the blanks for "f_____ a function because each student, each element of the_______, corresponds to ________ element of the _______.

I have attached pictures of the answer choices for this question below:

The slope's equation is:

 ⇒  [tex]\frac{y2-y1}{x2-x1}[/tex]

Since the two points are (-5,86) and (95,16)

 ⇒[tex]slope = \frac{16-86}{95--5} =-\frac{70}{100} =-\frac{7}{10}[/tex]

Thus the slope is -7/10.

Hope that helps!

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]

Only their product can produce a quadratic function

So the correct option is

Answer:

[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:

-1 11/12

Step-by-step explanation:

1/3=4/12 -2 1/4= -9/4 = -27/12

4/12 + -27/12 = -23/12

-23/12 = -1 11/12

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:

I believe would be 9•3•3=81 I hope that helps

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:

b is less than or equal to 0

Step-by-step explanation:

if we replace b with 0, the equation is true. if we take a number less then 0, for example -2, the equation is still true.

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.

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.

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°
