Answer:
Distance between the observer and the red car is [tex]250 Sin \frac{\pi}{3}t[/tex]
Step-by-step explanation:
Diameter of field = 500 m
Radius of field =[tex]\frac{Diameter}{2}=\frac{500}{2}=250 m[/tex]
Let R be the radius and the speed at which the car completes race be w
So,[tex]w=\frac{2\pi}{T}[/tex]
Car finished 5 laps in minutes = 30
Car finished 1 lap in minutes = [tex]\frac{30}{5}=6[/tex]
So, [tex]w=\frac{2\pi}{6}=\frac{\pi}{3}[/tex]
Refer the attached figure
Angle between car and observer = wt
So, Distance between the observer and the red car is give as A sin wt
So, Distance between the observer and the red car=[tex]250 Sin \frac{\pi}{3}t[/tex]
Someone help I don’t understand
Answer:
a)C
b)E
Step-by-step explanation:
a) You have to pick a vowel. There are three vowels and a total of 6 letters so it is 3/6 so the answer is C
b) Picking a card that is not T. None of the 6 letters are T so the probablity of picking a card with no T is 1. So the answer is E.

rectangular prism shown
below?
Answer:
C. 216 m^2
Step-by-step explanation:
The formula for the volume of a right solid is area of the base multiplied by the height. Following this formula, we multiply the given area of the base (27 m^2) by the height (8 m) to get 216 m^2, which is option C.

Write the slope-intercept for of the equation of the line with that passes through the point (2,-8) and is perpendicular to 2x+3y=15
Answer:
y = 3/2 x - 11
Step-by-step explanation:
Recall that a perpendicular line to the expression:
2 x + 3 y = 15
3 y = - 2 x + 15
y = - 2/3 x + 15/3
is going to have a slope equal to the opposite of the reciprocal of the original (-2/3) slope. So, the slope of the perpendicular line must be: 3/2.
We use this value in a general point-slope form of a line, where we use the point (2, -8) :
y - (-8) = 3/2 (x - 2)
y + 8 = 3/2 x - 3*2/2
y + 8 = 3/2 x - 3
y = 3/2 x - 3 - 8
y = 3/2 x - 11

According to the equation, how much would a person earn who works 40 hours?
What if the person got a $50 bonus and also worked some hours? How would this change the graph?
What if the person got a $2 per hour rate? How would this change the graph of the line?
What is slope? Write a conclusion about the ratio and slope.
The slope of the graph is $15 per hour. The linear function is given by y = 15x
What is a linear function?A linear function is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept
The graph passes through the point (1, 15) and (8, 120) is:
y - 15 = [(120 - 15)/(8 - 1)(x - 1)
y = 15x
For 20 hours; y = 15(20) = $300
If the person got a $50 bonus and also worked some hours, the graph would change because the y intercept would be 50.
If the person got a $2 per hour rate, the graph would change because the slope would be 2.
The slope of the graph is $15 per hour.

1/2 x - 12 = 12? Need Answer ASAP only have few mins left i studied whole night but forgot this question
Answer:
x = 48
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] x can be rewritten as [tex]\frac{x}{2}[/tex].
[tex]\frac{x}{2} - 12 = 12[/tex]
add 12 to both sides.
[tex]\frac{x}{2} = 12 + 12[/tex]
[tex]\frac{x}{2} = 24[/tex]
multiply both sides by 2.
[tex]x = 24 * 2[/tex]
x = 48

Bongeka purchased a new refrigerator and were expected to pay R1 684,00 five months ago and another R1 323,00 in eight months’ time. She could not make the payment five months ago, but after receiving a bonus at work, she rescheduled to repay the loan in two equal payments, the first due in two months and the second due in five months’ time. The payment at month five will settle the debt, therefore, the settlement date is month five. The debts and payments are subject to the same interest rate of 11,4% per annum, compounded monthly.
The discount factor computed shows that the value of each payment will be $1546.
How to calculate the payment?The following can be deduced from the information:
Payment due in 5 months = $1684
Payment due in 8 months = $1323
Annual interest = 11.40%
Monthly interest rate = 11.40%/12 = 0.95%
Present value of payment due 5 months ago = $1684 + (1 + 0.95%)⁵ = $1765.52
Present value of payment due 8 months ago = $1226.62
Total present value = $1765.52 + $1226.62 = $2992.14
After rescheduling, the payments will be in 2 months and 5 months.
Discount factor for payment due in 2 months = 0.9813
Discount factor for payment due in 5 months = 0.9538
Combined discount factors= 0.9360
Therefore, the value of each payment will be:
= $2992.14/(1 + 0.9360)
= $1546
