Answer:
1.41 x 10^-2
Step-by-step explanation:
1.8 x 10^-2 - 3.9 x 10^-33 = 18 x 10^-3 - 3.9 x 10^-3
= (18-3.9) x 10^-3
= 14.1 x 10^-3
= 1.41 x 10^-2

Solve the following proportion. Round your answer to two decimal places.
Answer:
x = 2
Step-by-step explanation:
[tex]\frac{x+1}{x+3}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )
5(x + 1) = 3(x + 3) ← distribute parenthesis on both sides
5x + 5 = 3x + 9 ( subtract 3x from both sides )
2x + 5 = 9 ( subtract 5 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2

Identify the domain of the function shown in the graph.
y
10
10
10
-10
A. X20
B. All positive real numbers
C. All real numbers
D. All positive integers
The domain of the function shown in the graph are all real numbers. Therefore, option C is the correct answer.
What is domain and range of the function?The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively.
The coordinate points from the given graph are (-2, 0) and (10, 6).
Here, slope m=(6-0)/(10+2)
= 6/12
= 1/2
= 0.5
Substitute m=0.5 and (x, y)=(-2, 0) in y=mx+c, we get
0=0.5(-2)+c
0=-1+c
c=1
So, equation of a line is y=0.5x+1
Find the domain by finding where the equation is defined. The range is the set of values that correspond with the domain.
Domain: (−∞,∞),{x|x∈R}
Range: (−∞,∞),{y|y∈R}
Therefore, option C is the correct answer.

Megan will multiply the first equation by 3 then add the result to the second equation.
What will be the resulting system of equations that produces the same solutions?
The resulting equation will be x + y = 4 and 4y =20
System of equationGIven the system of equation given as:
x + y = 4
-3x + y = 8
If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:
3x + 3y = 12
-3x + y = 8
Adding both equation
3y + y = 12 + 8
4y = 20
Hence the resulting equation will be x + y = 4 and 4y =20

A 6-kilogram bag of cement costs $24.81. What is the unit price, rounded to the nearest cent?
Answer:
$4.14
Step-by-step explanation:
To find the unit price, we divide $24.81 by 6.
24.81/6 = 4.135
The question says to round to the nearest cent so we round it to 4.14.
4.135 = 4.14
Are all polyhedrons solids?
Answer:
A polyhedron is a 3-dimensional solid made by joining together polygons. The word 'polyhedron' comes from two Greek words, poly meaning many, and hedron referring to surface. The polyhedrons are defined by the number of faces it has.

Answer:
x = 2√2
y = 2√6
Step-by-step explanation:
Consider the ratio of the two legs of the two smaller interior right triangles. (refer to attached diagrams for the triangles - I have outlined one in blue and the other in red)
These will be equal since the triangles are similar
shorter leg : longer leg
(blue triangle = red triangle)
⇒ x : 4 = 2 : x
⇒ x/4 = 2/x
⇒ x² = 8
⇒ x = √8
⇒ x = 2√2
Now we have x, we have the two legs of the right triangle with hypotenuse labelled y.
Using Pythagoras' Theorem a² + b² = c² (where a and b are the legs and c is the hypotenuse)
⇒ 4² + (2√2)² = y²
⇒ y² = 24
⇒ y = √24
⇒ y = 2√6
What is the measure of
Answer:
64.4
Step-by-step explanation:
In one of the trig formulas, it states sin <a/A = sin<b/B = sin<c/C
So we have in this case:
sin(70)/12 = sin x/14 Note: x is just a variable for the angle <ABC
14(sin70)/12 = sin x
sin^-1(14(sin70)/12) = x
x=64.4

Solve each two-step inequality and graph the solution set on a number line -17 < 3-5x
Answer:
[tex]x < 4[/tex]
Step-by-step explanation:
Given the following question:
[tex]-17 < 3-5x[/tex]
In order to find the answer, we will solve the inequality as if it is a regular two-step equation and then we will plot the answer on the number line.
[tex]-17 < 3-5x[/tex]
[tex]-17 < 3-5x=3-5x > -17[/tex]
[tex]3-5x > -17[/tex]
[tex]3-3=0[/tex]
[tex]-17--3=-20[/tex]
[tex]5x=-20[/tex]
[tex]\frac{5x}{5}=x[/tex]
[tex]20\div5=-4[/tex]
[tex]x < 4[/tex]
When plotting inequalities on the number line keep a few things in mind:
. 4 is greater than x, so the line will go towards the opposite direction of four
. < is a greater sign, it's not a greater or equal to sign (≤) which means it will be an open dot.
Hope this helps.
prove that if a is a factor of b and b is a factor of c, then a is a factor of c
Answer:
The set of numbers a = 3, b = 6, and c = 9 proves the hypothesis because 3 is a factor of 6 and 3 is a factor of 9. Property 1 states that therefore 3 is a factor of 9 + 3 =12, which we know is true because 3 × 4=12. You can prove that this property is true for all integers if you know what the term factor means.

Find a polynomial F(x ) of degree 5 that has the following zeros.
8(multiplicity 2) -2, -9, 0
Leave your answer in factored form.
F(x) = ?
Answer:
f(x) = x(x + 2)(x + 9)(x - 8)²
Step-by-step explanation:
Given x = h is a zero of f(x) then (x - h) is a factor
If h has multiplicity 2 then the factor is squared , that is (x - h)²
here the zeros are x = 8 of multiplicity 2 , x = - 2, x = - 9, x = 0
then (x - 8)² , (x - (- 2)) , (x - (- 9)) , x - 0 are the factors, that is
(x - 8)² , (x + 2) , (x + 9) and x
f(x) = x(x + 2)(x + 9)(x - 8)² ← in factored form
