Write an equation of the line that passes through (1, 2) and is perpendicular to the line y =1/3x + 4.
Answer:
y= -3x + 5
Step-by-step explanation:
negative reciprocial of the slope:
m=1/3
m=-3
Subsitube the point (1,2) into y=mx+b with new slope and solve for b:
y=mx+b
2=-3(1)+b
b=5

Here is some information from the practice round for several new Click Bots.
Determine the missing values. Enter them in the table.
Then describe your strategy.
Answer/Step-by-step explanation:
✅Azure:
Clicks = 17
Time (secs) = 2
Unit rate (clicks/sec) = [tex] \frac{17}{2} = 8.5 [/tex]
✅Bronze:
Clicks = 38
Time (secs) = 4
Unit rate (clicks/sec) = [tex] \frac{38}{4} = 9.5 [/tex]
✅Camson:
Clicks = 26
Time (secs) = ? = x
Unit rate (clicks/sec) = 10.4
Thus: [tex] \frac{26}{x} = 10.4 [/tex]
Multiply both sides by x
[tex] 26 = 10.4*x [/tex]
Divide both sides by 10.4
[tex] \frac{26}{10.4} = x [/tex]
[tex] 2.5 = x [/tex]
Time (secs) = x = 2.5
✅Desert:
Clicks = ? = x
Time (secs) = 4.2
Unit rate (clicks/sec) = 8.33
Thus: [tex] \frac{x}{4.2} = 8.33 [/tex]
Multiply both sides by 4.2
[tex] x = 8.33*4.2 [/tex]
[tex] x = 34.986 [/tex]
Clicks = x ≈ 35
✅ Emerald:
Clicks = 3
Time (secs) = ? = x
Unit rate (clicks/sec) = 7.5
Thus: [tex] \frac{3}{x} = 7.5 [/tex]
Multiply both sides by x
[tex] 3 = 7.5*x [/tex]
Divide both sides by 7.5
[tex] \frac{3}{7.5} = x [/tex]
[tex] 0.4 = x [/tex]
Time (secs) = x = 0.4
✅Fuschia:
Clicks = ? = x
Time (secs) = 0.75
Unit rate (clicks/sec) = 8
Thus: [tex] \frac{x}{0.75} = 8 [/tex]
Multiply both sides by 0.75
[tex] x = 8*0.75 [/tex]
[tex] x = 6 [/tex]
Clicks = x ≈ 6
Jason invests $325 in a bank account. The bank has an annual
interest rate of 24%. How much interest did his investment earn
after one year?
The amount of interest earned by Jason is $78.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific amount of time.
Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to calculate interest, the principal amount in simple interest remains constant.
Given that Jason invests $325 in a bank account. The bank has an annual interest rate of 24%.
The interest will be calculated as:-
SI = ( P x R x T ) / 100
SI = ( 325 x 24 x 1 ) 100
SI = $78
Hence, the simple interest is $78.

Find the maximum and minimum values of the function g ( θ ) = 5 θ − 6 sin ( θ ) on the interval [ 0 , π /2 ]
Answer:
Minimum value of the given function is 0
Maximum value of the given function
[tex]\frac{5\pi -12}{6}[/tex]
Step-by-step explanation:
Step(i):-
Given function g ( θ ) = 5 θ − 6 sin ( θ ) ...(i)
Differentiating equation (i) with respective to 'θ'
g¹ ( θ ) = 5 − 6 cos ( θ ) ...(ii)
g¹ ( θ ) = 5 − 6 cos ( θ ) =0
5 = 6 cos ( θ )
cos ( θ ) = 5 /6
Step(ii):-
Again Differentiating equation (ii) with respective to 'θ'
g¹¹ ( θ ) = − 6 (-sinθ ) = 6sinθ
Given interval
θ = 0 and θ= π/2
g ( 0 ) = 5 (0) − 6 sin ( 0 ) = 0
g(π/2) = 5(π/2) - 6 sin (π/2)
= 5(π/2) - 6

Convert to slope intercept form: 3x-4y=8 then graph the line on the grid
Answer:
y=3/4x-2
a=(8/3,0)
b=(0,-2)

Step-by-step explanation:
STEP 1
3x-4y =8 substract 3x from both sides
-4y=-3x+8 divide -4 to everything
y=3/4x-2
STEP 2
substitute 0 for y and solve for a (x-intercept)
The following system has a solution: x = 10, y = -3, z = 14. 3x + 7y - z = -5, 9x - y - 4z = 17, 5x - 12y - z = 0
