What is the image point of (0,-5) after a translation right 5 units and up 2 units
Answers
(5,-3)
Step-by-step explanation:
The x-axis is the left to right so if you start at 0 and go right 5, you are adding 5 (In a positive direction)
The y-axis is the up and down so starting at -5 and moving up the axis 2 you would add 2 back to the -5 since you are moving in the positive direction.

6. The temperature in a city on a Friday was 46.8 degrees Fahrenheit. On Saturday, the temperature was 63.5 degrees Fahrenheit. How much higher was the temperature on Saturday?
Answers
Answer:16.7
Step-by-step explanation:subtract 63.5 by 46.8 and you will get 16.7 degrees fahrenheit
If Friday and Saturday have such a temperature of 46.8 and 63.5 degrees Fahrenheit, respectively. Saturday's temperature is 16.7 degrees Fahrenheit lower than Friday's.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
It is given that the temperature in a city on a Friday was 46.8 degrees Fahrenheit. On Saturday, the temperature was 63.5 degrees Fahrenheit.
The temperature on Saturday is how much less than the temperature on Friday found as,
= 63.5 - 46.8
= 16.7° F
Thus, If Friday and Saturday have such a temperature of 46.8 and 63.5 degrees Fahrenheit, respectively. Saturday's temperature is 16.7 degrees Fahrenheit lower than Friday's.

g you are playing a game in which you flip 3 fair coins. it costs $1 to play the game, which must be subtracted from your winnings. Calculate the expected value for the game. If all coins show the same (all heads or all tails) you win $7, otherwise you lose your $1. The expected value of the game is
Answers
Answer:
Expected value of the game is $1.75
Step-by-step explanation:
The probability of getting a head or a tail on flipping a coin is 1/2 and so the probability of winning is 1/2 as we need all heads or all tails . There are 3 fair coins so the expected value of winning is given by =
P(1st coin =x =head)= 1/2
P(2nd coin =x =head)= 1/2
P(3rd coin =x =head)= 1/2
P(1st coin =x =tail)= 1/2
P(2nd coin =x =tail)= 1/2
P(3rd coin =x =tail)= 1/2
E(X= win) = ∑xP(x)= (1/2)³+(1/2)³= 1/8 + 1/8= 2/8
Expected value of winning the game is $ 7*2/8= 14/8=$ 1.75
$ 1.75- $1= $ 0.75
$ 0.75 (8) = $ 6
This means that for a total of $ 8 he gets $ 6.

Equation of the sinusoidal function
f(x) = 2sin(6x) - 7
What is sinusoidal function?A sinusoidal function is one with a smooth, repetitive oscillation. "Sinusoidal" comes from "sine", because the sine function is a smooth, repetitive oscillation.
Examples of everyday things which can be represented by sinusoidal functions are a swinging pendulum, a bouncing spring, or a vibrating guitar string.
Given,
Graph of a sinusoidal function intersects its midline at (0, -7) and then has a minimum point at (π/4, -9)
Let function be
f(x)=asin(bx)+c ---------(1)
When x = 0
f(0)=-7,
⇒ -7=asin(0)+c
⇒ c=-7.
When x = π/4
f(π/4)=-9,
⇒ -9=asin(bx)-7;
Sine is constrained to [-1,1], and since (π/4,-9) is a minimum,
sin(bx) must be equal to -1.
⇒ -9=a·(-1) - 7
⇒ a = 2
For minimum
-1=sin(π/4.b),
⇒ πb/4=3π/2,
⇒ b=6
Putting value of a, b, c in equation (1)
f(x) = 2sin(6x) - 7
Hence, f(x) = 2sin(6x) - 7 is the equation for sinusoidal function.

c. During the 11 -hour period, how much is delivered?

[tex]58.08\ \text{mL/hr}[/tex]
[tex]11\ \text{gtt/hr}[/tex]
[tex]638.88\ \text{mg}[/tex]
Step-by-step explanation:
33 % dextrous solution ( 33 mg per 100 mL of solution)
1.936 L of the solution is given over an 11-hour period
So the flow rate in mL/hr is
[tex]\dfrac{1.936\times 10^3}{11}=176\ \text{ml/hr}[/tex]
The flow rate in ml/hr is [tex]176\ \text{ml/hr}[/tex]
Flow rate of dextrous in mL/hr is
[tex]0.33\times 176=58.08\ \text{mL/hr}[/tex]
The flow rate dextrous in mL/hr is [tex]58.08\ \text{mL/hr}[/tex]
Each mL contains 16 drops so flow rate in gtt/h is
[tex]\dfrac{176}{16}=11\ \text{gtt/hr}[/tex]
The flow rate in units of gtt/hr is [tex]11\ \text{gtt/hr}[/tex]
The mass of dextrous delivered 11 hours in mg is
[tex]0.33\times 1.936\times 10^3=638.88\ \text{mg}[/tex]
The mass of dextrous delivered 11 hours in mg is [tex]638.88\ \text{mg}[/tex]

Answer:
$60
Step-by-step explanation:
20 half dollars means that there's 10 dollars in it (because you divide 20 by 2 since 2 half dollars make one dollar)
It takes 4 quarters to make one dollar and if there's 200 quarters then there's 50 dollars in it (200 divided by 4 is 50)
