Step-by-step explanation:
the other answer is correct.
just for a little bit of explanation :
the first position after the decimal point is for tenths. the second position for hundredths. the third for thousandths. then ten-thousandths, hundred-thousandths, millionths, ...
so, you would need 1000 thousandths to have a 1 at the first position before the decimal point. everything less than that has to be a number after the decimal point. and thousandths have to end (writing from left to right) with the thousandths-position. hundredths with the hundredths-position and so on.
What is the y-intercept of function f?
A. 1
B. -1
C. -2
D. 5
Answer:
1
Step-by-step explanation:
The y intercept is when x =0
We need to use the second equation
-x+1 since -2 < 0 <3
0+1
The y intercept is 1
Give the slope and the y-intercept of the line y=6x – 1. Make sure the y-intercept is written as a coordinate.
Answer:
slope = 6
y-intercept is (0,-1)
Step-by-step explanation:
the equation y = 6x-1 is written in slope-intercept form so it's easy to find the slope and the y-intercept
Find the area of the shaded region in square units. Show your reasoning.
Answer:
40 square units
Step-by-step explanation:
First of all, lets say that square has side [tex]l[/tex], so, the area unit is [tex]l^2[/tex]
the diagonal's square is [tex]l\sqrt{2}[/tex]
CALCULATION OF TRIANGLES'S AREA (there are 4 triangles)
[tex]A_{triangles}=4*base*heigh*0.5=2*(l\sqrt{2} )(2l\sqrt{2} )=8l^2[/tex]
CALCULATION OF MAIN SQUARE AREA
[tex]A_{square}=side*side=(4\sqrt{2} l)(4\sqrt{2} l)=32l^2[/tex]
TOTAL AREA
[tex]A_{total}=A_{triangles}+A_{square}=8l^2+32l^2=40l^2[/tex]
A soup pot in the shape of a cylinder has a radius of 5 inches and a
height of 10 inches. How much soup can the pot hold? *
A) 750.8 cubic inches
B) 785.0 cubic inches
C) 525.7 cubic inches
D) 780.0 cubic inches
Answer:
B)785.0 cubic inches
Step-by-step explanation:
amount of soup the pot can hold is equal to its volume
Volume of a cylinder is πr²h
π(5inches)²x 10inches
785.39816339744830
~785.0 cubic inches
Write the corresponding Hindu -Arabic numeral for the following
CCCXLlX=
Pls tell
9514 1404 393
Answer:
349
Step-by-step explanation:
In Roman numerals, C=100, L=50, X=10, V=5, I=1. Values are additive except when a lower value precedes a higher value. In that case, the lower value is subtracted.
The value here is 10 -1 +50 -10 +100 +100 +100 = 349.
__
Additional comment
Letters are assigned to 1 and 5 and those values multiplied by 10 or 100. When you get to 4000 and above, special forms apply. By convention, only unit values within a factor of 10 are subtracted. In the above number, 49 is written XLIX, not IL.

maya raised 286.00
lian raised 192.84 less than maya
rei earned 113.25 more than lian
what is the total amount of money raised by all three?
Answer:
585.57
Step-by-step explanation:
Maya got 286.00
if lian got 192.84 less than we do 286-192.84 which is 93.16
if lian got 93.16, we add 113.25 to 93.16 to get rei's amount.
113.25 + 93.16 = 206.41
Now we add all their amounts, 286+93.16+206.41
585.57
The one-to-one functions g and h are defined as follows
Answer:
[tex]g^-^1(x)=-8[/tex]
[tex]h^-^1(x)=\frac{x-4}{3}[/tex]
[tex](h^-^1 \ o\ h)(-3)=-3[/tex]
Step-by-step explanation:
When given the following functions,
[tex]g=[(-2,-7),(4,6),(6,-8),(7,4)][/tex]
[tex]h(x)=3x+4[/tex]
One is asked to find the following,
1. Question 1
[tex]g^-^1(4)[/tex]
When finding the inverse of a function that is composed of defined points, one substitutes the input given into the function, then finds the output. After doing so, one must substitute the output into the function, and find its output. Thus, finding the inverse of the given input;
[tex]g^-^1(4)[/tex]
[tex]g(4)=6\\g(6)=-8\\g^-^1(4)=-8[/tex]
2. Question 2
[tex]h^-^1(x)[/tex]
Finding the inverse of a continuous function is essentially finding the opposite of the function. An easy trick to do so is to treat the evaluator (h(x)) like another variable. Solve the equation for (x) in terms of (h(x)). Then rewrite the equation in inverse function notation,
[tex]h(x)=3x+4\\\\h(x)-4=3x\\\\\frac{h(x)-4}{3}=x\\\\\frac{x-4}{3}=h^-^1(x)[/tex]
[tex]h^-^1(x)=\frac{x-4}{3}[/tex]
3. Question 3
[tex](h^-^1 \ o\ h)(-3)[/tex]
This question essentially asks one to find the composition of the function. In essence, substitute function (h) into function ([tex]h^-^1[/tex]) and simplify. Then substitute (-3) into the result.
[tex]h^-^1\ o\ h[/tex]
[tex]\frac{(3x+4)-4}{3}\\\\=\frac{3x+4-4}{3}\\\\=\frac{3x}{3}\\\\=x[/tex]
Now substitute (-3) in place of (x),
[tex]=-3[/tex]
The angles shown below are supplementary:
what is the value of x
Answer:
[tex]x=12[/tex]
Step-by-step explanation:
By definition, supplementary angles add up to 180 degrees. Therefore, we can set up the follow equation to solve for [tex]x[/tex]:
[tex]10x+60=180,\\10x=120,\\x=\boxed{12}[/tex]
Answer:
x=12
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
10x+60=180
Subtract 60 from both sides:
10x=120
Divide 10 to both sides:
x=12

The function f(x) = x² +9 and the other function P is given by P(x) = f(x) - 34 ÷x + 5 find P (5 )
Answer:
32.2
Step-by-step explanation:
Given :
f(x) = x² +9
P(x) = f(x) - 34 ÷ x + 5
P(5) =?
Substitute 5 for X on P(x)
P(5) = f(5) - 34 ÷ x + 5
f(5) = 5² + 9 = 25 + 9 = 34
P(5) = 34 - 34 ÷ 5 + 5
According to PEMDAS
-34 ÷ 5 = - 6.8
P(5) = 34 - 6.8 + 5
P(5) = 34 - 1.8
P(5) = 32.2

The number of arrivals per minute at a bank located in the central business district of a large city was recorded over a period of 200 minutes with the results shown in the table below.
Complete parts (a) and (b)
Arrivals Frequency
0 21
1 46
2 40
3 36
4 25
5 20
6 8
7 3
8 1
a. Compute the expected number of arrivals per minute.
μ=___( please type as an integer or a decimal)
b. Compute the standard deviation
σ=___(please round to three decimal places as needed)
Answer:
a. μ = 25
b. σ = 16.496
Step-by-step explanation:
Note: See the attached excel for the calculation of Mean and Deviation from Mean.
Let: N = Number of observation = 9
F = Frequency
Therefore, we have:
a. Compute the expected number of arrivals per minute. μ=___( please type as an integer or a decimal)
From the attached excel file, we have:
Total F = 200
Therefore, we have:
μ = Mean = Total of F / (N - 1) = 200 / (9 - 1) = 25
b. Compute the standard deviation σ=___(please round to three decimal places as needed)
From the attached excel file, we have:
Total (F - μ)^2 = 2,177
σ = Standard deviation = (Total of (F - μ)^2 / (N - 1))^0.5 = (2,177 / (9 - 1))^0.5 = 16.496

Answer:
P: $0.12/kWh; M: $0.15/kWh
$285 from company P
Step-by-step explanation:
The cost per kWh from Company P is found by dividing the cost by the corresponding number of kWh:
$150/(1250 kWh) = $0.12/kWh
The cost per kWh from Company M is the coefficient of x in the equation:
$0.15/kWh
__
Company P provides power for a lower cost. The cost from Company P for 2375 kWh is ...
(2375 kWh)×($0.12/kWh) = $285 . . . cost for 2375 kWh

O Jada should use the tank of golf balls.
1b. Explain your reasoning."
3 points
Your answer
Answer:
Jada should use the tank of golf balls
Step-by-step explanation:
Jada should choose the tank that has a higher probability of choosing a ball with even number from.
Tank of tennis balls has two even numbers out of the ten balls (2, 4)
Tank of golf balls has seven even numbers out of the ten balls.
Tank of golf balls would give Jada more chance to pick an even number to win the game
Therefore, Jada should use the tank of golf balls
