Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

If f(x) = -8x - 4 and g(x)
which statement is true?
7x + 3,
Click on the correct answer.
9 is not in the domain of fºg.
9 is in the domain of fºg.
Answer:
9 is in the domain of f(g(x))
Step-by-step explanation:
f(g(x)) = -8*g(x) - 4
= -8*( 7x+3) - 4
= -56x - 24 - 4
= -56x - 28
= -28(2x + 1)
f(g(9)) = -28(2*9 + 1)
= -28*19
= -532
Since 9 can be plugged into the compound function, it is in the domain.

Circle A has a diameter of 4 inches, a circumference of 12.56 inches, and an area of 12.56 square inches. The diameter of circle B is 2 inches, the circumference is 6.28 inches, and the area is 3.14 square inches. SHOW ALL STEPS.
Part A: Using the formula for circumference, solve for the value of pi for each circle. (10 points)
Part B: Use the formula for area and solve for the value of pi for each circle. (10 points)
Part C: What observation can you make about the value of pi for circles A and B? (10 points)
Answer:
Part A:
Formula for circumference: C = diameter x pi
=> pi = C/diameter
=> pi(A) = 12.56/4 =3.14
=> pi(B) = 6.28/2 = 3.14
Part B:
Formula for area: A = radius^2 x pi = (diameter/2)^2 x pi
=> pi = A/(diameter/2)^2
=> pi(A) = 12.56/(4/2)^2 = 12.56/4 = 3.14
=> pi(B) = 3.14/(2/2)^2 = 3.14/1 = 3.14
Part C:
pi(A) = pi(B) = 3.14 in both ways of calculation derived from circumstance and area.
=> pi is a constant value: 3.14
Answer:
A) pi = 3.14
B) pi = 3.14
C) pi has the same value for all calculations, pi is a constant
Step-by-step explanation:
Circumference = pi × d
12.56 = 4 × pi
pi = 3.14
6.28 = 2 × pi
pi = 3.14
Area = pi × r²
12.56 = pi × (4/2)²
12.56 = 4pi
pi = 3.14
3.14 = pi × (2/2)²
3.14 = pi

Step-by-step explanation: 180-90=90
90/2=45
Answer:
x= 45
Step-by-step explanation:
There are 180 degrees in a triangle
The box in the corner is 90
180-90 = 90
There are 90 degrees left
The lines means that the two sides are equal so the angles must be equal
The two angles are x and x
x+x = 90
2x=90
Divide by 2
2x/2 = 90/2
x = 45

A drawer has 9 pairs of white socks 7 pairs of black socks 6 pairs of brown socks and 3 pairs of blue socks you get dressed each morning in the dark in randomly reach into the sock drawer to get your socks after a day of wearing the socks you do not replace them until the weekend after you have done some laundry what is the probability that your sock selection goes in the following order for this week?
P(Black then white then white the brown then blue)=____
Answer:
0.0014 = 0.14%
Step-by-step explanation:
First we need to find the total number of pairs:
9 + 7 + 6 + 3 = 25 pairs
Then, we need to find the probability for each case:
First socks black: 7 pairs over 25: P1 = 7/25
Second socks white: 9 pairs over 24: P1 = 9/24 = 3/8
Third socks white: 8 pairs over 23: P1 = 8/23
Fourth socks brown: 6 pairs over 22: P1 = 6/22 = 3/11
Fifth socks blue: 3 pairs over 21: P1 = 3/21 = 1/7
The final probability will the the product of all probabilities above:
P = (7/25) * (3/8) * (8/23) * (3/11) * (1/7) = 0.0014 = 0.14%
Answer:
567/398475 in fraction or 0.0014229249 in decimal
Step-by-step explanation:
In the question, we are given these values
Total pair of socks = 25 pairs of socks
9 pairs of white socks
7 pairs of black socks
6 pairs of brown socks
3 pairs of blue socks
From the question, we can see that, this is probability without replacement.
Hence,
P(Black then white then white the brown then blue)=
7/25 × 9/24× 8/23 ×6/22 × 3/21
= 9072/6375600
= 567/398475
Therefore, the Probability of picking a Black socks then white socks then white socks , then brown socks and then blue socks = 567/398475 in fraction or 0.0014229249 in decimal

x² + 2x + y² + 4y = 20
We complete the square in both x and y. For each we add half the linear coefficient, squared. So (2/2)²=1 for x and (4/2)²=4 for y. We add them to both sides to keep the equation the same.
x² + 2x + 1 + y² + 4y + 4 = 20 + 1 + 4
Now the left side is the sum of squares and the right side is the squared radius.
(x + 1)² + (y + 2)² = 5²
Standard form is (x-p)² + (y-q)² = r² for center (p,q) and radius r. Note the minus signs.
We read off the answer:
Answer: Center (-1, -2), radius 5.
Solve the system using the method of you choice:
-x + 4y = 12
5x - 2y = -6
Answer:
(0, 3)
Step-by-step explanation:
Let's first eliminate x. To do this, multiply all three terms of the first equation by 5:
-5x + 20y = 60
5x - 2y = -6
----------------------
18y = 54, so that y = 3.
Substituting 3 for y in the first equation yields:
-x + 4(3) = 12, or -x = 0. Thus, x = 0, and the solution is
(0, 3)

The base of the square pyramid shown has an area of 576 square units. If the slant height of the pyramid is 20 units, what is the height of the pyramid?
18 units
13.4 units
16 units
31.2 units
Answer:
Option C - 16 units
Step-by-step explanation:
Since the base is a square and it has an area of 576 sq.units, thus, if the side length of the base is x, then;
x² = 576
x = √576
x = 24
To get the height, we will divide this side length by 2 and use Pythagoreas Theorem.
Since, we are told that the pyramid has a slant height of 20 units,
So using pythagoras theorem, we can find the height of the pyramid as;
h² = 20² - (24/2)²
h² = 400 - 144
h² = 256
h = √256
h = 16 units

Which system of equations has a solution of approximately (–0.6, 0.8)?
Answer:
[tex]14x+5y=-5\\2x-5y=-5[/tex]
Step-by-step explanation:
The given equations are
[tex]2x-5y=-5\\11x-5y=15\\9x+5y=5\\14x+5y=-5[/tex]
Let's demontrate that the system
[tex]14x+5y=-5\\2x-5y=-5[/tex]
Has (-0.6, 0.8) as solution, approximately.
If we sum those equations, we have
[tex]16x=-10\\x=\frac{-10}{16} \approx -0.625[/tex]
Then, we use this value to find the other one
[tex]2x-5y=-5\\2(-0.625)-5y=-5\\-5y=-5+1.25\\y=\frac{-3.75}{-5} \approx 0.75[/tex]
As you can see, the answers aproximates to (-0.6, 0.8).
Therefore, the right system is

drop-down menus to explain Aisha's mistake.
Answer:compares the absolute value ,score of 16 represents greatest lost ,highest score farthest away from 0, on a number line that number is 10
Step-by-step explanation:ig/ 6k.mar
A score of -16 represents the lowest of points for these four turns.
The number for Aisha's highest score will be turn 2 on the number line.
That number is 10.
What is number?A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.
here, we have,
Since the options of the drop down menu are not included, you should choose any option similar to lowest.
Aisha's highest score was obtained in turn 2 and that is 10.
we have,
Aisha is comparing absolute terms, that is why she believes that -16 represents a good score, while in reality is the worst she got.
Hence, A score of -16 represents the lowest of points for these four turns.
The number for Aisha's highest score will be turn 2 on the number line.
That number is 10.

Find the area of the shaded region. Round your answer to the nearest hundredth.
Answer:
86
Step-by-step explanation:
the radius of one circle is 5. the area of a circle is pi x r^2. 5 times 5 is 25. 25 times 3.14 is 78.5. since there are 4 circles, you must multiply 78.5 by 4, which is 314. Next, find the area of the square. 20 times 20 is 400. to find the area of the shaded part, subtract 314 from 400. The answer is 86.
