Please help. FLVS.
Answer:
g(3) = 11Step-by-step explanation:
g(x) = x² + 2
To find g(3) , substitute the value of x that's 3 into g(x) , that is for every x in g (x) replace it with 3
That's
g(3) = 3² + 2
= 9 + 2

An airplane takes off over flat area when it is 2500' above the Earth it has covered 3000' on the ground how many feet approximately has it flow through the air
Answer:
3905.12 feet
Step-by-step explanation:
we can form a triangle in order to use the Pythagorean theorem: a² + b² = h²
where:
a = distance covered on the ground
b = height above the Earth
3000² + 2500² = h²
h² = 9000000 + 6250000 = 15250000
h = √15250000
h = 3905.12 feet

Three sisters have ages that are consecutive odd integers. Their combined ages is 51.
How old is the youngest sister?
Records show that Oliver is typically 10–30 minutes late for his shift at work. The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve. John and Oliver are working a shift that starts at the same time. John always arrives 8 minutes late. What percentage of the time does Oliver arrive within 10 minutes of John's arrival time? O 26.7% O 33.3% 2 O 40% O 50%
Answer:
40%
Step-by-step explanation:
10 minutes late would mean 18 minutes late on the graph. The graph goes from 10-30 which creates a difference of 20. 8 divided by 20 equals 40 percent.
40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.
Given that,
Oliver is typically 10–30 minutes late for his shift at work.
The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve.
John and Oliver are working a shift that starts at the same time. John always arrives 8 minutes late.
We have to determine,
What percentage of the time does Oliver arrive within 10 minutes of John's arrival time?
According to the question,
Oliver is typically 10–30 minutes late for his shift at work.
John and Oliver are working a shift that starts at the same time.
John always arrives 8 minutes late.
From the complete information, the probability distribution will be:
[tex]= \dfrac{1}{b-a}\\\\= \dfrac{1}{30-10}\\\\= \dfrac{1}{20}[/tex]
Here, John always arrives 8 minutes late.
Therefore,
The percentage of the time that Oliver arrives within 10 minutes of John's arrival time is,
[tex]\rm = 8 \times \dfrac{1}{20}\\\\= \dfrac{2}{5}\\\\= 0.4 \times 100 \\\\= 40 \ Percent[/tex]
Hence, 40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.

Step-by-step explanation:
Answer:
the answer you are looking for is A
Step-by-step explanation:
2x^3 + 3x^2 -11x -6 divided by x - 2
p(x)= x-2
g(x)= 2x^3 + 3x^2 - 11x - 6
first we have to find the zero of the polynomial of x-2
p(x)= x-2 = 0
x=2
therefore,
p(x)= 2x^3 + 3x^2 - 11x - 6
p(2)= 2*2^3 + 3*2^2 - 11*2 - 6
= 2*8 + 3*4 - 11*2 - 6
= 16 + 12 - 22 - 6

HELP!!!!Find the measurement of 4(Explain)
Answer:
26°
Step-by-step explanation:
The angle 5 is equal to angle 154° as these are both corresponding angles and corresponding angles are equal.
Angles on a straight line equal 180°, so if we take 154° from 180° we get angle 4, which is 26°
I hope that helped!
XY and WZ are parallel.
Angle 1 + 154° = 180° (Linear pair)
→ Angle 1 = 180 - 154
→ Angle 1 = 26°
Now, Angle 4 = Angle 1 (Alternative interior angles)
→ Angle 4 = 26°
Hence, we got the answer.
do you divide or multiply for w in the equation A = lw
Answer:
Multiplication
Step-by-step explanation:
This looks like the equation for the area of a rectangle.
Area = Lenght * Width
Given that the "l" variable and the "w" variable or next to each other without '/' or '\' , then we can safely say this a multiplication operation.
If there is no symbol between variables, it is assumed to be short-hand for multiplication instead of writing '*', '.', or 'x' in-between the variables.

Step-by-step explanation:
Laura bought 55 shares of stock for $3.50 per share last year. She paid her broker a 1% commission. She sold the stock this week for $2 per share, and paid her broker a $10 flat fee. What were Laura’s net proceeds? Round to the nearest cent. What was her capital gain or loss?
Answer:
cp of 55 shares = 3.50 * 55 = 192.5
commission amount = 1% *192.5 = 1.925
Total invest = 192.5 + 1.925 = 194.425
sp of 1 share = 2
sp of 55 share = 2*55 = 110
Earning from shares = 110
since earning is less than invest, Laura has loss of (194.425 - 110) = 84.425
Laura has a loss of $84.425 for the cost price of $192.5.
What is an expression?Mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Cost price of 55 shares = 3.50 x 55 = 192.5
Commission amount = 1% *192.5 = 1.925
Total invest = 192.5 + 1.925 = 194.425
The selling price of 1 share = 2
The selling price of 55 share = 2*55 = 110
Earning from shares = 110
Since earnings are less than investment, Laura has a loss of (194.425 - 110) = $84.425
Therefore, Laura has a loss of $84.425 for the cost price of $192.5.

The least-squares regression line Sˆ=0.5+1.1L models the relationship between the listing price and the actual sales price of 12 houses, with both amounts given in hundred-thousands of dollars. Let L represent the listing price and S represent the sales price.
Answer:
For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.
Step-by-step explanation:
The sales price is not predicted to increase by $1.1; it is predicted to increase by $110,000 because S is measured in hundred-thousands of dollars. The sales price will not decrease by $110,000; it is predicted to increase by $110,000.
A linear regression is represented as [tex]^\wedge y = mx + c[/tex].
The true option is: E. For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.
Given that:
[tex]^\wedge S = 0.5 + 1.1L[/tex]
From the general linear equation, we have:
[tex]1.1 \to[/tex] The slope
[tex]0.5 \to[/tex] The y-intercept
The slope is the difference between the sales price of one listing and the next.
From the question, we understand that the listed amount is in 100,000's.
This means that there is an increment of [tex]\$1.1 \times 100000[/tex] between the sales price of concurrent listing
So, we have:
[tex]\$1.1 \times 100000 =\$110000[/tex]
From the list of given options (see attachment), we can then conclude that (e) is correct.
Hence, for each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

-14 - 8x = -2(-3x + 7)
solution? No solution? Infinite?
Answer:
the answer is one solution
Answer:
x=0
This means that there is a solution.
Step-by-step explanation:
Step 1- Distribute into the parenthesis
-14-8x= (-2)-3x+(-2)7
Step 2- Multiply
-14-8x= 6x-14
Step 3- Add 8x to both sides.
-14x-8x= 6x-14
+8x +8x
Step 4- Add 14 to both sides.
-14= 14x-14
