Write a function rule for the table.
A. p = 7.50h
B. p = h + 15
C. p = 15h
D. h = 7.50p
Answers
Answer:
p = 7.50h
I got this correct, the answer is A. p= 7.50h
Step-by-step explanation:
The answer would be d because every two hours someone works they get $15 and for the equation we must know how much they work for one hour so that it works with the equation (we'd have to simplify it down do how much paid up per hour). so half of 15 is 7.5 so the equation would be p=7.50h (standing for $7.50 per hour).
The correct answer is: [D]: " p = 7.50 h " .
________________________________________________
The pay, "p" , is a function of the hours worked.
When h = 2, (h = number of hours);
the pay, "p" , is equal to " 7.50 * 2 " = 15.00 dollars" ; as shown on table.
When h = 4 ; p = " 7.50 * 4 = 30.00 dollars" ; as shown on table .
When h = 6 ; p = " 7.50 * 6 = 45.00 dollars" ; as shown on table.
When h = 8 ; p = " 7.50 * 8 = 60.00 dollars" ; as shown on table.

Give your answers as exact whole numbers or as decimals to 3 s.f.
Answers
Answer:
i. a = -6 ii. b = 12 iii. 100 iv. 26.6°
Step-by-step explanation:
Since the weight of the object is 20 N and directed downwards, its vector is -20j. Now, since the particle is in suspension, AP + BP = -20j
So, since AP = ai + 8j and BP = 6i + bj,
AP + BP = -20j
ai + 8j + 6i + bj = -20j
ai + 6i + 8j + bj = -20j
(a + 6)i + (8 + b)j = -20j
(a + 6)i + (8 + b)j = 0i - 20j
equating the components on both sids,
a + 6 = 0 and 8 + b = 20
a = -6 and b = 20 - 8 = 12
i. The value of a is -6
ii. The value of b is 12
iii. The magnitude of the tension in string AP is?
since AP = ai + 8j = -6i + 8j
magnitude of AP = √[-6² + 8²] = √[36 + 64] = √100 = 10
iv. The angle that string BP makes with the vertical is?
Since BP = 6i + bj = 6i + 12j, the angle it makes with the horizontal is Ф = tan⁻¹(12/6) = tan⁻¹(2) = 63.44°.
Thus, the angle it makes with the vertical is thus 90° - 63.44° = 26.56° (complementary angles) ≅ 26.6° to 3 s.f
1) The values of a and b of the given vectors are respectively; -6 and 12
2) The magnitude of the tension in string AP is; 10
3) The angle that string BP makes with the vertical is; 26.6°
What is the magnitude of the tension?
We are told that the weight of the particle P is 20 N. Since the particle is suspended by two strings, then its' direction is downwards and as such its vector is -20j.
By equilibrium;
AP + BP = -20j
1) We are given the tension vectors;
AP = ai + 8j and BP = 6i + bj,
Thus;
ai + 8j + 6i + bj = -20j
(ai + 6i) + (8j + bj) = -20j
(a + 6)i + (8 + b)j = -20j
(a + 6)i + (8 + b)j = 0i - 20j
Equating the components of both sides gives;
a + 6 = 0 and 8 + b = 20
Solving gives;
a = -6 and b = 20 - 8 = 12
Thus, the values of a and b are -6 and 12
2) The magnitude of the tension in string AP is gotten from resolution of the tension vector AP;
AP = ai + 8j = -6i + 8j
Thus, magnitude of AP = √(-6² + 8²) = √(36 + 64) = √100 = 10
3) The angle that string BP makes with the vertical is gotten from;
BP = 6i + bj = 6i + 12j
Thus, the angle it makes with the horizontal;
θ = tan⁻¹(12/6) = tan⁻¹(2) = 63.44°.
Angle it makes with the vertical = 90° - 63.44° = 26.56° ≈ 26.6°

George says that an account that earns 4% interest compounded annually and an account that earns 2% interest compounded semi-annually will be worth the same if the principals are the same
Answers
Answer:
the account won't yield the same amount despite the same principal amount.
Step-by-step explanation:
To test this assertion :
Let principal = $1000
t = 1 year
Compound interest formula :
A = P(1 + r/n)^nt
P = principal ; r = rate, n = number of times interest is compounded per period ; t = time
Account A :
Rate = 4% annually
A = 1000(1 + 0.04/1)^1
A = 1000 * 1.04 = $1040
Account B:
Rate = 2% compounded semianually ; n = 12 /6 = 2
A = 1000(1 + 0.02/2)^1*2
A = 1000(1.01)^2
A = 1000 * 1.0201
A = $1020.1
From the result, the account won't yield the same amount despite the same principal amount.

Have a nice day.
Answer:
5/4x + 10
Step-by-step explanation:
If it's parallel, the slope will remain the same.
To find the y-intercept, you have to plug in the coordinates into the equation which is, y = 5/4x + b.
y = 5/4x + b
0 = 5/4 (-8) + b
0 = -10 + b
10 = b
The equation is 5/4x + 10.
