Answer: [tex]1.2447 * 10^4[/tex]
Step-by-step explanation:
1.2447 × [tex]10^4[/tex]
( scientific notation )
Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point.
Answer:
1.2447 x 10^4
Step-by-step explanation:
The answer would be 1.2447 times 10 to the fourth power because to find the first part (1.2447), move the decimal place one place to the right. (.12447-> 1.2447)
Next, count how many places are to the right of the decimal.
1.2447 = 4
So, that would get you 1.2447 times 10 to the power of 4.

Step-by-step explanation:
Kira is using the figure shown to prove the Pythagorean theorem. She starts by writing the
equation (a + b)2 – 2 = 4( ab) because she knows two equal ways to represent the area
of the shaded region. Which best describes the next steps Kira should take to complete her
proof?
Answer:
B. Simplify both sides of the equation to get [tex]a^2 + 2ab + b^2 - c^2 = 2ab[/tex]; then subtract 2ab and add [tex]c^2[/tex] to both sides of the equation
Step-by-step explanation:
Given
[tex](a + b)^2 - c^2 = 4(\frac{1}{2}ab)[/tex]
Required
Describe the next steps to
First, we open all brackets
[tex](a + b)^2 - c^2 = 4(\frac{1}{2}ab)[/tex]
[tex](a + b)(a + b) - c^2 = 4(\frac{1}{2}ab)[/tex]
[tex]a^2 + 2ab + b^2 - c^2 = 4 * (\frac{1}{2}ab)[/tex]
[tex]a^2 + 2ab + b^2 - c^2 = 2ab[/tex]
At this point, options A and C are incorrect because they didn't present the right result of the expression.
So, we have options B and D to consider
The next step is to subtract 2ab from both sides
[tex]a^2 + 2ab + b^2 - c^2 - 2ab = 2ab - 2ab[/tex]
Collect like terms
[tex]a^2 + b^2 - c^2 +2ab - 2ab = 2ab - 2ab[/tex]
[tex]a^2 + b^2 - c^2 = 0[/tex]
Lastly, to prove the Pythagoras theorem, the equation has to be in form of[tex]a^2 + b^2 = c^2[/tex]; meaning the [tex]c^2[/tex] is added to both sides; See below
[tex]a^2 + b^2 - c^2 = 0[/tex]
Add [tex]c^2[/tex] to both sides
[tex]a^2 + b^2 - c^2 + c^2= 0 + c^2[/tex]
[tex]a^2 + b^2 = c^2[/tex]
At this point, only option B completes Kira's proof
Answer:
It’s B
Step-by-step explanation:
I did the test
In a board game, when you land on a specific square, you must roll a die. If the result is an odd number, you receive four times the result, in dollars. If the result is even, you must pay five times the result, in dollars.
Determine the expectation.
a. 5 - 4
b. 4 x ( 1 + 3 + 5) x 1/2 - 5 ( 2 + 4 + 6) x 1/2
c. 0
d. 5 x 1/2 - 4 x 1/2
Answer:
Option B is correct.
It represents exactly the expectation.
Hope this helps!
:)
Answer:
The answer is B
STEP BY STEP EXPLANATION BOIZ:
if its an odd number four times the result = 4 x (1 + 3 + 5)
If result is even you must pay five times the result = 5(2 + 4 + 6)
So 4 x (1 + 3 + 5) x 1/2 - 5(2+4+6) x 1/2 is the answer

The radius of a circle is 4 miles. What is the area of a sector bounded by a 180 arc?
Answer:
The area of sector is [tex]25.12 miles^2[/tex]
Step-by-step explanation:
Radius of circle = 4 miles
We are supposed to find the area of a sector bounded by a 180 arc
[tex]\theta = 180^{\circ}[/tex]
Area of sector =[tex]\frac{\theta}{360^{\circ}} \pi r^2[/tex]
Area of sector = [tex]\frac{180^{\circ}}{360^{\circ}} \times \frac{22}{7} \times 4^2[/tex]
Area of sector = [tex]25.12 miles^2[/tex]
Hence The area of sector is [tex]25.12 miles^2[/tex]
1) Find a quadratic equation that has solutions x = 0 and x = 5 Give your answer
without brackets.
2) Find a quadratic equation that has two solutions x = 7
Give your answer without brackets.
1) You need to work this problem backwards.
x=0 and x=5 and those are the roots so the factoring must have looked something like this:
(x-0)(x-5) Then you would FOIL it:
x^2-5x-0-0 Then simplify:
x^2-5x.
2) Do the same thing with this problem.
x=7 and x=7
(x-7)(x-7)
x^2-7x-7x+49
x^2-14x+49
I hope that this helps.

What is the value of x in the figure? Enter your answer in the box.
Answer:
x = 65
Step-by-step explanation:
2x + 15 and 145 are vertical angles and congruent, thus
2x + 15 = 145 ( subtract 15 from both sides )
2x = 130 ( divide both sides by 2 )
x = 65
Answer:65
Step-by-step explanation:
2x+15=145. Because opposite angles are equal
2x+15=145
Collect like terms
2x=145-15
2x=130
Divide both sides by 2
2x/2=130/2
x=65

Evaluate 5 + 1.3 • 8.7
Step-by-step explanation:
16.31
.......................
Answer:
16.31
Step-by-step explanation:
You want to start with multiplying because of PEMDAS, so
1.3 x 8.7
so 7 x 3 = 21, and carry the two, then 7 x 1 = 7 + 2 = 9.
at the bottom you now have that it equals 9.1
so, now you start your next line and put a 0.
then, 8 x 3 = 24, of course carry the 2, and 8 x 1 = 8 + 2 = 10.
you will now have 10.40 under that
you then add 9.1 + 10.40 to get your answer of
11.31
lastly, just simply add
11.31 + 5
and you get your final answer of 16.31
What are the zeros of the function shown in the graph?
Answer: x = 2, -4
Step-by-step explanation:
The zeros of a function are where the function crosses the x-axis, in this case, the function crosses the x-axis at 2 and -4, so 2 and -4 are the zeros of this function.
Hope this helps.
Answer:
By definition, the zeros of a function f(x) are all the values x for which f(x) = 0. In other words, the zeros of a function f(x) are the intersections of the graph of f(x) with the axis of x. Therefore, to identify the zeros of the function shown, identify the values of x in which the graph intersects the horizontal axis.
what is 10 1/3 x 1/4? that is, what is ten and one third times one fourth?
Answer: 31/12, or 2 7/12
Step-by-step explanation: The answer is actually very simple. All you have to do is to simplify 10 1/3 into 31/3, as 10x3+1=31. Then, you have to multiply 31/3 with 1/4. Do a simple fraction multiplication, and you get 31/12, or 2 7/12 if your teacher is asking for a mixed number. Sometimes simplifying is better

Answer:
0.1, 1/2, 0 .7 , 3/4
Step-by-step explanation:
3/4, 0.7, 1/2 , 0.1
Change the numbers to the same form
3/4 = .75 1/2 = .5
.75 , .7 , .5 , .1
We want the numbers from least to greatest or smallest to biggest
.1 is the smallest
then .5
then .7
then .75

Find the area of the shaded region.
Express the area in factored form.
Answer:
(x-1)(x+3)
Step-by-step explanation:
The area of the big green rectangle is just x(x+2) which is [tex]x^2+2x[/tex]. (Excluding the interior rectangle) The shaded area is just this minus three which is [tex]x^2+2x-3[/tex]. In factored form this is (x-1)(x+3).

I really need help figuring out what x and y are
Answer:
x = 44, y = 37
Step-by-step explanation:
∠1 and ∠ 4 are adjacent angles and are supplementary, thus
3x + 4 + x = 180
4x + 4 = 180 ( subtract 4 from both sides )
4x = 176 ( divide both sides by 4 )
x = 44
------------
∠ 1 and ∠ 3 are vertical angles and congruent, thus
4y - 12 = 3x + 4 = 3(44) + 4 = 132 + 4 = 136 ( add 12 to both sides )
4y = 148 ( divide both sides by 4 )
y = 37

three-fourths the square of a number
Answer:
i think it is D i am sorry if it is wrong
Step-by-step explanation:
one negative number is 4.5 more than another number. the sum of the squares of these numbers is 46.25. Find both
Answer:
y = -6.5 and x = 2
Step-by-step explanation:
Let one negative number be -y and another number be x
We are given that one negative number is 4.5 more than another number
So, -y=x+4.5
We are also given that The sum of the squares of these numbers is 46.25.
So,[tex]x^2+(-y)^2=46.25\\x^2+(x+4.5)^2=46.25\\x^2+x^2+20.25+18x=46.25\\2x^2+18x=26.25\\x^2+9x=13.125\\x^2+9x-13.125=0\\[/tex]
x=-6.5,2
When x = -6.5
-y=x+4.5
-y=-6.5+4.5
-y=-2
y=2
When x = 2
-y=x+4.5
-y=2+4.5
-y=6.5
y=-6.5
So, y = -6.5 and x = 2
