what is the value of -2(x+5)?
Answer:
[tex] - 2(x + 5) = (- 2x - 10)[/tex]
(-2x-10) is the right answer.The variable d models drone's distance from the safe zone (in meters) t seconds after the drone started flying. D=-5t+4. What is the speed of the drone?
Answer:
v = 5 m/s
Step-by-step explanation:
The variable d models drone's distance from the safe zone (in meters) t seconds after the drone started flying is :
d = -5t+4
We need to find the speed of the drone. Speed is the rate of change of position.
[tex]v=\dfrac{dd}{dt}\\\\=\dfrac{d}{dt}(-5t+4)\\\\v=-5\ m/s[/tex]
Hence, the speed of the drone is 5 m/s.
A car is traveling with a velocity of 65.0 km/h. In the next 15 minutes the car gradually slows down at the end of the 15 minutes the car is traveling at 45.0 km/h what is the average acceleration of the car during the time it slows down?
Answer:
- 0.006173 m/s²
Step-by-step explanation:
Given :
Initial Velocity, u = 65km/hr = (65*1000) / 3600 = 18.056 m/s
Final velocity, v = 45 km/ hr = (45*1000) / 3600 = 12.5 m/s
Time at which change in velocity occurred = 15 minutes = 15 * 60 = 900 s
Acceleration = Change in velocity with time
Acceleration = (v - u) / t
Acceleration = (12.5 - 18.056) / 900
Acceleration (deceleration) = - 5.556 / 900
Deceleration = - 0.006173 m/s²

the table shows for a quadratic function.
what is the average rate of change for this function for the interval from from x=3 to x=5
Answer:
the average rate of change is 12
Step-by-step explanation:
The computation of the average rate of change is shown below:
As from the attached table
f(b) = f(5) = 32
f(a) = f(3) = 8
Now the average rate of change is
= (32 - 8) ÷ ( 5 - 3)
= (24 ÷ 2)
= 12
Therefore the average rate of change is 12
So the same is relevant and considered too

Find they -intercept and -x intercept of the line. -9x-2y=-14
Answer:
the x-intercept is when y equals 0, so it's 14/9, which is 1 5/9
the y-intercept is when x equals 0, so it's 7
Step-by-step explanation:
Answer:
Step-by-step explanation:
y -intercept, put x = 0:
-9(0) - 2y = -14
2y = 14
y = 7.
So y-intercept is at (0, 7).
x -intercept, put y = 0:
-9x - 2(0) = -14
-9x = -14
x = 14/9/
So x-intercept is at (14/9, 0).
use what you already know to find a,b and c. input each value NEED HELP
Answer:
b=100
a=80
c=100
Step-by-step explanation:
to find b we know that in a straight angle there is 180 degrees and since we already know that one side is 80 degrees we just need to substract 180 by 80 to get 100 degrees.
since its parallel lines we can confirm that 80degrees and r are coresponding angles so r=80.Which also means a and r are alternate angles so a=80.
Lastly to find c we need to do the same thing as we did with b. Which means c=100
franklin st. is parallel to washington st. What is the value of x?
Answer:
x = 73°Step-by-step explanation:
The angles 107° and x are supplementary angles, therefore sum to 180°:
107° + x = 180°x = 180° - 107°x = 73°1. The volume of a rectangular shape 5 feet

Answer:
B = 41.81
Step-by-step explanation:
sin B = opposite/ hyp
sin B = 2/3
Take the inverse sin of each side
sin ^-1 sin (B) =sin ^-1 (2/3)
B =41.8103149
To the nearest hundredth
B = 41.81

Answer:
x=4
Step-by-step explanation:
both sides, add 7
Hey there!
“x – 3 = 7”
• FIRST: ADD by 3 on BOTH sides
• x – 3 + 3 = 7 + 3
• CANCEL out: –3 + 3 because that gives you 0
• KEEP: 7 + 3 because that helps us solve for your x-value
• NEW EQUATION: x = 7 + 3
• FLIP THE EQUATION: 7 + 3 = x
“Solve above and you have your answer!”
• ANSWER: x = 10 ☑️

Joseph has saved $325. He wants to purchase a surfboard that costs $785. If he saves $12 each week from the money he earns mowing yards and another $6 each week from his allowance, how many weeks will it take Joseph to save enough to buy the surfboard?
Answer: 25.6 weeks
Step-by-step explanation:
He has saved $325 already so the amount left to purchase the surfboard is:
= 785 - 325
= $460
He saves $12 and $6 every week.
= $18.
Number of weeks left:
= 460/18
= 25.6 weeks

Answer:
Step-by-step explanation:
[tex]y(t>1) = x(t) + y(t-1)\\x(t>1) = 1.2x(t-1)\\y(1) = x(1) = 100\\\\y(t>1) = 1.2x(t-1) + y(t-1)\\y(2) = 1.2x(1) + y(1) = 120+100 = 220\\y(3) = 1.2x(2) + y(2) = 144+220 = 364\\y(4) = 1.2x(3) = y(3) = 172.8+364=536.8\\[/tex]
