Answer:
D. 6×10^-3
Step-by-step explanation:
When powers of the same base are divided, the power of the denominator is subtracted from the power of the numerator.
[tex]\dfrac{0.000024}{4\times10^{-3}}=\dfrac{24\times10^{-6}}{4\times10^{-3}}=\dfrac{24}{4}\times10^{-6-(-3)}=\boxed{6\times10^{-3}}[/tex]

The weekly budget for a youth club is $22 000
The youth club plan to spend 27% of the budget
on a sports programme.
How much money is this?
Answer:
$5,940
Step-by-step explanation:
x/22 000 = 27/100
(part/whole)=(%/100)
(x)(100)=(22)(22 000)
Butterfly Method
100x=594 000
Divide by 100 on both sides to get x
x=5940

Solve the equation
2x2+8x -1 = 0
by completing the square.
Give your answers correct to 2 decimal places.
Answer:
x ≈ - 4.12 , x ≈ 0.12
Step-by-step explanation:
2x² + 8x - 1 = 0 ( add 1 to both sides )
2x² + 8x = 1 ( factor out 2 from the first two terms )
2(x² + 4x) = 1
To complete the square
add/ subtract ( half the coefficient of the x- term )² to x² + 4x
2(x² + 2(2)x + 4 - 4) = 1
2(x + 2)² - 8 = 1 ( add 8 to both sides )
2(x + 2)² = 9 ( divide both sides by 2 )
(x + 2)² = [tex]\frac{9}{2}[/tex] ( take square root of both sides )
x + 2 = ± [tex]\sqrt{\frac{9}{2} }[/tex] = ± [tex]\frac{3}{\sqrt{2} }[/tex] ( subtract 2 from both sides )
x = - 2 ± [tex]\frac{3}{\sqrt{2} }[/tex]
Then
x = - 2 - [tex]\frac{3}{\sqrt{2} }[/tex] ≈ - 4.12 ( to 2 dec. places )
x = - 2 + [tex]\frac{3}{\sqrt{2} }[/tex] ≈ 0.12 ( to 2 dec. places )

We have to given that;
Sam bought a soft drink for four dollars and six candy bars.
And, He spent a total of 22 dollars.
Let the cost of each candy = x
So, We can formulate by the given condition,
⇒ $4 + 6x = $22
⇒ 4 + 6x = 22
⇒ 6x = 22 - 4
⇒ 6x = 18
⇒ x = $3

plz help! what is the end of behavior of f(x)?
Answer:
B
Step-by-step explanation:
The end behavior of a function is how the graph behaves as it approaches negative and positive infinity.
Let's take a look at each end.
As x approaches negative infinity:
As x approaches the left towards negative infinity, we can see that the graph is shooting straight upwards.
Therefore, as [tex]x\rightarrow-\infty[/tex], our function f(x) is increasing and increasing up towards positive infinity.
Therefore, the end behavior at the left will be:
[tex]\text{As } x\rightarrow-\infty, f(x)\rightarrow\infty[/tex]
As x approaches (positive) infinity:
As x approaches the right towards positive infinity, we can see the that graph is also shooting straight upwards.
Therefore, the end behavior will be exactly the same. As x approaches positive infinity, f(x) also approaches positive infinity.
Therefore, the end behavior at the right will be:
[tex]\text{As } x\rightarrow \infty, f(x)\rightarrow \infty[/tex]
Therefore, our answer is B.

Answer: E. (x+5)^2 + (y-5)^2 = 9
Step-by-step explanation:
The equation of a circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.
We are given that the center is (-5,5), which means that h = -5 and k = 5.
We are also given that the radius (r) = 3, which means r^2 = 9.
Therefore, the equation should be (x-(-5))^2 + (y-5)^2 = 9.
--> (x+5)^2 + (y-5)^2 = 9
solve for x and y 7x + 5y = 12 and 7y - 2x = 11

Answer:
How do you multiply 18 by 5/6? Here we will show you step-by-step how to solve 18 times 5/6, which can be written as follows:
18
x
5
6
Step 1: Setup
First of all, note that 18 is the same as 18/1 since 18 divided by 1 is 18. Therefore, start by setting up the problem like this:
18
1
x
5
6
Step 2: Multiply
Multiply the numerators together (18 x 5 = 90) and multiply the denominators together (1 x 6 = 6) and make it into one fraction like so:
90
6
Step 3: Minimize
The greatest common factor of 90 and 6 is 6. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:
15
1
Step 4: Convert
Convert the improper fraction above to a whole number to get the answer:
15
That's it! Now you know how to calculate 18 times 5/6.
Answer:
15
Step-by-step explanation:
First turn the 18 into a fraction: 18/1
Next put the two fractions into an equation: 5/6 x 18/1 = ?
Then we mutiply the top numbers and the bottom numbers: 90/6
Finally since the fraction is top heavy, we divide to make it eithera lower fraction or a full number: 90/6 = 15
Your final answer will be 15 :)

Step-by-step explanation:
Both are vertical to one another. Vertical angles usually have the same degree.
Answer:

Step-by-step explanation:
because the two lines are straight, and we know that the angles opposite to each other are identical, and since FHC is equal to EHD, its size must also be equal.
