Answer:
Step-by-step explanation:
if we are supposed to solve [tex]x^{2}[/tex] + 2x + 9 = 0 there here is the solution
using the quadratic formula
= (-2 ± [tex]\sqrt{2^{2}-4*9 }[/tex] )/2
= (-2 ± [tex]\sqrt{-32}[/tex]) / 2
= (-2 ± i [tex]\sqrt{16*2}[/tex])/2
= (-2 ± i 4[tex]\sqrt{2}[/tex])/2
= -1 ± i 2[tex]\sqrt{2}[/tex]
complex number land :)
if i add negative 2 + negative 9 and then divide 2 what do i get
Answer:
-6.5
Step-by-step explanation:
-2 + -9 =-11 ÷2=-6.5
Answer:
Depends. If you were asking 2+-9/2, according to the rules of PEMDAS it would be -2.5 but by the way you wrote that, I'm assuming you meant (2+-9)/2 which is -3.5.

Answer:
3 cm
Step-by-step explanation:
Answer:
2.5cm
Step-by-step explanation:
The shapes are similar and so have a scale-factor. We can find the scale-factor by dividing one of the lengths that we know on the bigger shape by the corresponding side on the smaller shape.
For example: PQ/LM = 6/3 = 2
Now that we know to get from the larger shape to the smaller shape, we have to multiply by 2. We can use this scale factor to find the length of the side MN.
QR = MN x 2
MN = QR/2 = 5/2 = 2.5cm

what does 3w =30 mean a. 6 b.9 c.10 d.12
Answer:
w = 10
Step-by-step explanation:
3w = 30
Divide each side by 3
3w/3 = 30/3
w = 10
Answer: Correct answer is c.10
Step-by-step explanation:
3w = 30 (It means you divide)
/3 /3 (You would divide both sides by 3)
w=10 (Then you're left with your answer w=10)
A

are points on a circle with
A
C
as a diameter.
A

C
is a right-angled triangle.
Work out the total area of the regions shaded in the diagram.
Give your answer correct to 1 decimal place.
Answer:
Area of the shaded portion = 54.5 cm²
Step-by-step explanation:
Solve first for the area of the circle:
[tex]area \: of \: circle = \pi {r}^{2} \\ = \pi( \frac{d}{2} )^{2} \\ = \pi( \frac{10}{2} )^{2} \\ = 25\pi \: or \: 78.5398 {cm}^{2} [/tex]
Then, compute for the area of the triangle:
[tex]area \: of \: triangle = \frac{1}{2} \times base \times height \\ = \frac{1}{2} ( {8})(6) \\ = 24 {cm}^{2} [/tex]
Since we only needed the shaded portion, we have to subtract the area of the triangle from the area of the circle
[tex]25\pi {cm}^{2} - 24 {cm}^{2} = 54.5398 {cm}^{2} [/tex]

Which of the following tables represents a function?
Answer:
The third table
Step-by-step explanation:
It's the third table because each input does not repeat, so it means all of the inputs are unique
Repeating inputs (x) make it not a function
As their is no mention of test assuming it's not a test question
Solution
Now
As per definition of function
Every domain has an unique rangef(x)=yThing we have to see here is x values must not repeated more than once
In table 3
It follows the definationTable 3 is a function

colin buys a tv for £780. It depreciates at a
rate of 5% per year. how much will
it be worth in 6 years
Answer:
Discussing interest starts with the principal, or amount your account starts with. This could be a starting investment, or the starting amount of a loan. Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5. The total amount you would repay would be $105, the original principal plus the interest.

Answer:
Second table (B)
Input: 0, 1, 2
