find the distance of line segment AB between the points at (8,0) and (5,9)
Answer:
Approximately 3.605 units
Step-by-step explanation:
AB= B -A = [tex]\left[\begin{array}{ccc}5\\9\end{array}\right][/tex] - [tex]\left[\begin{array}{ccc}8\\0\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}-3\\9\end{array}\right][/tex]
|AB| = √x²+y² = √(-3)²+2² = √9+4 =√13 = 3.605 units
Tony rounded each of the numbers 1,183 and 1, 145 to the nearest hundred. Which choice correctly compares the rounded
numbers?
1,180 > 1.150
1,100 = 1, 100
1,200 < 1, 100
1,200 > 1,100
Answer:
1,200 > 1,100
Step-by-step explanation:
This is because 1,183 is rounded up to the nearest hundred which is 1200 (since 8 which is the tens digit is greater than 5) and 1,145 is rounded down to the nearest hundred which is 1,100 (since 4 which is the tens digit is less than 5).
So, 1,200 > 1,100
In the current year Aveeno reported net income of $50,400which was a 12% increase over prior year net income Compute prior year net income
Answer:
$45000
Step-by-step explanation:
Given data
Net income =$50,400
Let the prior year income be x
12/100*x +x= 50400
0.12x+x= 50400
1.12x= 50400
x= 50400/1.12
x= $45000
Hence the prior year income is $45000

A park charges $13 for one round of miniature golf and a reduced fee for each additional round played. If Tom paid $43 for 6 rounds of miniature golf, what is the reduced fee for each additional round played? The reduced fee for each additional round played is $____
Answer:
$6
Step-by-step explanation:
the fixed cost = $13
the variable cost is unknown. It depends on the rounds played. according to the question the additional rounds played is 5 (6 - 1) .Represent the variable cost with x
the next equation can be formed using variables from the question :
$43 = $13 + 5x
collect like terms
$43 - $13 = 5x
$30 = 5x
divide both sides of the equation by 5
x = $6

If (2x^2-5x+7)-(4x^2+2x-11), what is the result?
Answer:
- 2x² - 7x + 18
Step-by-step explanation:
Given
(2x² - 5x + 7) - (4x² + 2x - 11) ← distribute parenthesis
= 2x² - 5x + 7 - 4x² - 2x + 11 ← collect like terms
= - 2x² - 7x + 18

Which is not a characteristic of an exponential parent function?
O A. It passes through (0,1).
O B. The domain is all real numbers.
O C. It goes through the origin.
O D. The range is positive real numbers (y > 0).
Given:
The characteristic of an exponential parent function in the options.
To find:
Which is not a characteristic of an exponential parent function?
Solution:
The exponential parent function is:
[tex]y=b^x[/tex]
Where, [tex]b>0[/tex].
At [tex]x=0[/tex],
[tex]y=b^0[/tex]
[tex]y=1[/tex]
It means the function passes through the point (0,1) but it does not passes through the origin. So, the statement in option A is true but the statement in option C is false.
The domain of the exponential parent function is all real numbers and the range is positive real numbers (y > 0). So, the statements in the options B and D are true.
Therefore, the correct option is C.
I need help to get the answer,
Answer:
4.25 hours
Step-by-step explanation:
A fully charged phone would be at 100%, so we'll set y equal to 100 and solve for x:
100=20x+15
85=20x
4.25=x
So Sammi's phone will be fully charged in 4.25 hours.
Answer:
4.25 hours
Step-by-step explanation:
"Fully charged" means the percentage should be 100%.
Substitute 100 for y then solve for x.
[tex]100=20x+15\\85=20x\\x=\frac{85}{20}\\x=4.25 \text{ hours}[/tex]

Answer:
BC ≈ 4.85 m
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{5.4}[/tex] ( cross- multiply )
5.4 × cos26° = BC , then
BC ≈ 4.85 m ( to 3 s f )

What is the simplest form for 20:36
Answer:
5:9
Step-by-step explanation:
20÷4=5
36÷4=9
If you divide 20 by 4 you get 5. If you divide 36 by 4 you get 9. You need to be able to divide each number in the ratio by the same number. In this case, that number is 4. You can tell that this ratio (5:9) is in simplest form because 5 is a prime number and cannot be simplified any more.
If you want to check this divide the ratio by 2 two times. Or just divide it by 4 once.
20÷2=10 → 10÷2=5
36÷2=18 → 18÷2=9

Answer:
A, B, D
Step-by-step explanation:
Answer:
A, B, D, E
Step-by-step explanation:
1. 100 = 100%, so seeing that there are 55 boys and 45 girls, we can go ahead and turn those into percentages, making this answer correct.
2. Once again, 100 = 100%, so 17 = 17%
3. "10/55 of those" isn't implying this is the boys only, but rather everyone, so this statement is not correct.
4. 10/35 of the students who chose math are girls. We can see that on the graph.
5. 8 + 8 = 16. Those are both the same number and half and half of the boys and girls...
Hope this helped!
What is an
equation of the line that passes through the points (-3,-2) and (3,6)?
Answer:
y = 4/3x + 2
Step-by-step explanation:
y2 - y1/ x2 - x1
6 - (-2)/ 3 - (-3)
= 8 / 6
= 4/3
y = 4/3x + b
6 = 4/3(3) + b
6 = 4 + b
2 = b
