What is 0.5 as a fraction in simplest form
Answer:
1/2
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
0.5 is said as "five-tenths". This is because it is one place after the decimal. It would then become five-tenths, written as: 510. You would then simplify the fraction: 510=12

Express 2x²+20x+7 in the form (x+p)²+q
Answer:
f(x) = (x + 5)² - 21.5
Step-by-step explanation:
Step 1: Subtract both sides by 7
2x² + 20x = -7
Step: GCF and divide
2(x² + 10x) = -7
x² + 10x = -7/2
Step 3: Complete the Square
x² + 10x + 25 = -7/2 + 25
(x +5)² = 43/2
Step 4: Subtract 43/2 to both sides
(x + 5)² - 43/2
And we have our equation!

If f(x) = x and g(x) = 2x + 7, what is g(x)
when x = -6?
Answer:
g(-6) = -5
Step-by-step explanation:
g(x) = 2x + 7
Let x = -6
g(-6) = 2(-6) +7
= -12 +7
= -5
Answer:
-5
Step-by-step explanation:
g(x) = 2x + 7
Put x as -6.
g(-6) = 2(-6) + 7
g(-6) = -12 + 7
g(-6) = -5
Given f(x)= √7x and g(x) = 1/x-8 which value is in the domain of f^o g

HELP ME PLEASE! So I’m working on this practice page before I start my quiz but I don’t understand these two problems, I was hoping someone would help me.
Answer: y = 1/2x - 6
Step-by-step explanation:
#4 We are going to use slope intercept form, (y = mx+b)
1. The line crossing the y-intercept at (0,-6)
2. The slope is 1/2 (increasing by 1 then over 2 --> RISE OVER RUN)
3. Make the equation: y= 1/2x - 6
Answer: 3 . y = -1/3 + 4/3 4. y= 1/2x -6
Step-by-step explanation:
3. In the first graph they have the coordinates, (-2,2) and (4,0). We have to solve for the slope and the y-intercept in other to write and equation.
To find the slope we have to find the change in the y values and divide it by the difference in the x values.
2-0 = 2
-2 -4 = -6
2/-6 = -1/3 Now we know that the slope is -1/3 so we need to find the y-intercept.
2= -1/3(-2) +b where be is the y intercept.
2= 2/3 + b
-2/3 -2/3
b= 4/3
Now we could write the equation as y= -1/3 + 4/3
4. The same with number 4.
We will find the slope and the y intercept by using some points on the number line.
(0,-6) This already have the y-intercept graphed so we will need to just find the slope.
(0,-6)
(4,-4)
-6 - (-4) = -2
0 - 4 = -4
-2/-4 = 1/2
Equation: y = 1/2x -6
solve: 5x + 4 < 3 – 3x
Answer:
x = -1/8
Step-by-step explanation:
The greater than sign can be replaced with an equal sign to solve.
5x + 4 < 3 – 3x =>
5x + 4 = 3 - 3x =>
+3x -4 +3x - 4
---------------------------
8x = -1
x = -1/8
You invest $700 in an account that pays an interest rate of 6.5% compounded continuously calculate the balance of your account after 20 years round your answer to the nearest hundred
Answer:
$2466.55
Step-by-step explanation:
We use the formula for Compound Amount, the amount gotten after a particular time, to find the balance:
[tex]A = P(1 + r)^t[/tex]
where P = Principal = $700
r = rate = 6.5% = 0.065
t = time elapsed 20 years
Therefore:
[tex]A = 700(1 + 0.065)^{20}\\\\A = 700(1.065)^{20}\\[/tex]
A = $2466.55
The balance of the account will be $2466.55
Which real-world transformations can be represented by dilations? Select two options. 1. turning a camera to take a photograph 2. cropping a photograph to a square by cutting only one side 3. reducing a photograph to half its dimensions 4. enlarging a photograph to double the dimensions 5. moving a photograph to a different page
Answer:
3 and 4
Step-by-step explanation:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size so here reducing a photograph to half its dimensions and enlarging a photograph to double the dimensions is dilation.
=> For dilation, we use a certain scale factor
=> In the 3rd option, scale factor is 1/2
=> In the 4th option, scale factor is 2.

Which number line represents the solution set for the inequality 3(8 – 4x) < 6(x – 5)?
Answer:
2nd option.
Step-by-step explanation:
3(8 - 4x) < 6(x - 5)
24 - 12x < 6x - 30
-12x - 6x < -30 - 24
-18x < -54
x > 3
Answer:
2nd graph
Step-by-step explanation:
3(8 – 4x) < 6(x – 5)
Distribute
24 -12x < 6x -30
Add 12x to each side
24-12x+12x < 6x-30+12x
24 < 18x-30
Add 30 to each side
24+30 < 18x-30+30
54 <18x
Divide by 18
54/18 < 18x/18

The length of the segment EF is 12 cm. What is the length of ED? *
DE = 6 SqRt 3 cm
DE = 3 SqRt 12 cm
DE = 6 SqRt 12 cm
DE = 3 SqRt 3 cm
Answer:
ED = 6√3 cm
Step-by-step explanation:
This is a 30-60-90 triangle. Remember the rules. Hypotenuse is always 2x. Leg across from 60° is x√3. Leg across from 30° is x.
12 = 2x
x = 6
ED = x√3
ED = 6√3
Jeremiah invested $x at a 6% simple annual interest rate account. Six times that amount was invested at an 9% simple annual interest rate account. How much was invested at the 6% account if the total annual return was $800.00?
Answer:
Step-by-step explanation:
We will make a table with the values for both a 6% account and a 9% account.
The formula for this problem is Prt = I, where P is the amount invested in each account, r is the interest rate each carries in decimal form, t is the time in years, and I is the interest earned from the multiplication of the 3 previous values. We don't know how much is invested in either account, but we do know that no matter how much is invested in the 6% account, there is 6 times that in the 9% account. We know that the 6% account has a decimal rate of .06 and that the 9% account has a decimal rate of .09. "Annual" means 1 year, so the time is 1 year. Filling in the table, then:
P * r * t = I
Acct 6% x .06 1
Acct 9% 6x .09 1
What we do with those number is multiply them straight across each row to get the amount of interest earned from each:
P * r * t = I
Acct 6% x * .06 * 1 = .06x
Acct 9% 6x * .09 * 1 = .54x
The amount of Interest for both ADDS UP to 800; therefore:
.06x + .54x = 800 and
.6x = 800 so
x = 1333.33
That's how much was invested in the account that earned 6% interest annually.

Answer:
(i) 12.25
(ii) 12.25.
Step-by-step explanation:
(1) cot^2 O = (7/2)^2 = 49/4
= 12.25.
(2) (1 - sin O) ( 1 + sin O) 1 - sin^2 O cos^2 O
---------------------------- = ------------- = --------------
(1 - cos O)(1 + cos O) 1 - cos^2 O 1 - cos^2 O
As cot O = 2/7, tan O = 1 /2/7 = 7/2.
Hypotenuse of the right triangle = √( 2^2 + 7^2)
= √53
So cos O = 7/√53
Therefore the original function = cos^2 O / (1 - cos^2 O)
= (7/√53)^2 / (1 - (7/√53)^2 )
= 49/53 / 4/53
= 49/4.

If x = 1 is a common root of ax² +ax + 2 = 0 and x² + x + b = 0 , then ab =
Answer:
ab = 2
Step-by-step explanation:
Given equations
ax² +ax + 2 = 0
x² + x + b = 0
root of both the equation
x= 1
then we can plug in x = 1 in both the equation
ax² +ax + 2 = 0 x² + x + b = 0
a*1² +a*1 + 2 = 0 1² + 1 + b = 0
a +a + 2 = 0 1 + 1 + b = 0
2a + 2 = 0 2 + b = 0
2a = - 2 b = -2
a = -2/2 = -1
Thus,
a = -1
b = -2
a*b = -1*-2 = 2
ab = 2
Toilet rolls are sold in packs of four how many toilet rolls are there in nine packs
Answer:
36 toilet rolls
Step-by-step explanation:
1 pack consist of 4 rolls
So,
1 pack = 4 toilet rolls
Multiplying both sides by 9
=> 1×9 = 4×9
=> 9 packs = 36 toilet rolls
Each term in the sequence below is equal to the sum of two previous terms.
...a,b,c,d,e,f....
All of the following are equal to the value of "d" EXCEPT...
A. e-c
B. b + c
C. a + 2b
D. e - 2b
E. f-e
Hey there! :)
Answer:
D, e - 2b.
Step-by-step explanation:
Check each answer choice using the pattern given:
A. e - c = d because c + d = e. This is correct.
B. b + c = d. This is correct.
C. a + 2b = d because c = a + b. This is correct.
D. e - 2b ≠ d. This is incorrect.
E. f - e = d because d + e = f. This is correct.
Therefore, the only answer that does not equal "d" is D, e - 2b.
