Answer:
y = 1/2x
Step-by-step explanation:
Choose two points- I chose (10,5) and (0,0)
Find the slope using y2-y1/x2-x1
Use y - y1 = slope (x -x1) to get your equation
The answer should be y =1/2x

Answer:
x = 10°
Step-by-step explanation:
By the inscribed angle theorem, the measure of an inscribed angle is half the measure of the intercepted arc.
So
x =( x + 10 )/2
2x = x + 10
2x - x = 10
x = 10°

Melissa and Robbie are flying remote control gliders. The altitude of Melissa’s glider, , in feet, is modeled by this function, where s is time, in seconds, after launch. The altitude of Robbie’s glider is modeled by function r, where s is time, in seconds, after launch.
Answers
Answer:
Robbie Glider
Step-by-step explanation:
Given
Melissa Glider
[tex]m(s) = 0.4(s^3 - 11s^2 + 31s - 1)[/tex]
Robbie Glider
See attachment for function
Required
Which reaches the greater maximum within the first 6 seconds
Melissa Glider
First, we calculate the maximum of Melissa's glider
[tex]m(s) = 0.4(s^3 - 11s^2 + 31s - 1)[/tex]
Differentiate:
[tex]m'(s) = 0.4(3s^2 - 22s + 31)[/tex]
Equate to 0 to find the maximum
[tex]0.4(3s^2 - 22s + 31) = 0[/tex]
Divide through by 0.4
[tex]3s^2 - 22s + 31 = 0[/tex]
Solve for s using quadratic formula:
[tex]s = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 3; b = -22; c = 31[/tex]
So:
[tex]s = \frac{22 \± \sqrt{(-22)^2 - 4*3*31}}{2*3}[/tex]
[tex]s = \frac{22 \± \sqrt{112}}{6}[/tex]
[tex]s = \frac{22 \± 10.6}{6}[/tex]
Split:
[tex]s = \frac{22 + 10.6}{6}\ or\ s = \frac{22 - 10.6}{6}[/tex]
[tex]s = \frac{32.6}{6}\ or\ s = \frac{11.4}{6}[/tex]
[tex]s = 5.4\ or\ s = 1.9[/tex]
This implies that Melissa's glider reaches the maximum at 5.4 seconds or 1.9 seconds.
Both time are less than 6 seconds
Substitute 5.4 and 1.9 for s in [tex]m(s) = 0.4(s^3 - 11s^2 + 31s - 1)[/tex] to get the maximum
[tex]m(5.4) = 0.4(5.4^3 - 11*5.4^2 + 31*5.4 - 1)[/tex]
[tex]m(5.4) = 1.24ft[/tex]
[tex]m(5.4) = 0.4(1.9^3 - 11*1.9^2 + 31*1.9- 1)[/tex]
[tex]m(5.4) = 10.02ft[/tex]
The maximum is 10.02ft for Melissa's glider
Robbie Glider
From the attached graph, within an interval less than 6 seconds, the maximum altitude is at 3 seconds
[tex]r(3) = 22ft[/tex]
Compare both maximum altitudes, 22ft > 10.02ft. This implies that Robbie reached a greater altitude

In a lab experiment, 100 bacteria are placed in a petri dish. The conditions are such
that the number of bacteria is able to double every 13 hours. How long would it be, to
the nearest tenth of an hour, until there are 156 bacteria present?
Answers
Answer: 8.34 hr
Step-by-step explanation:
Given
Initially, 100 bacteria are placed in a Petri dish
bacteria doubles in every 13 hours
So, a function that defines this relation is given as
[tex]\Rightarrow B=B_o(2)^\frac{t}{13}[/tex]
where, [tex]B=\text{No of bacteria at any time}[/tex]
[tex]B_o=\text{Intial bacterias}\\t=\text{time in hrs}[/tex]
for [tex]B=156[/tex]
[tex]\Rightarrow 156=100\times 2^{\frac{t}{13}}\\\\\Rightarrow 1.56=2^{\frac{t}{13}}\\\\\Rightarrow t=13\times \dfrac{\ln (1.56)}{\ln (2)}\\\\\Rightarrow t=13\times0.641=8.34\ hr[/tex]

What is the formula for a triangle prism
Answers
Answer:
Remember the formula for calculating volume is: Volume = Area by height. V = A X h.
For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.
So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

If you have $3250 how many board feet can you buy if the cost per board foot is $2.29?
Answers
Answer:
If i am right i think its 1419
Step-by-step explanation:
3250/2.29= about 1419
Answer:
1419.21= 1419
Step-by-step explanation:
Divide the amount of money you have with the cost price of what you want to buy.
$3250/$2.29=1419.213974
The answer is a decimal. But we can not have a unit as decimal so we have to round it down to the nearest whole number.
Therefore = 1419
