Answer:
336
Step-by-step explanation:
The first year added $18 so just double the lat 2 digits
The amount $300 after 1 year and 2 year become $318 and $337.08 respectively.
It is given that the deposit amount is $300 in an account with a 6% annual interest rate.
It is required to find the money after 1 year and 2 year.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A= P(1+r)^t[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
t = How long the money is deposited or borrowed (in years)
We have P = $300
r = 6% = 0.06
t = 1 years
Putting the values in the formula, we get;
[tex]\rm A= 300(1+0.06)^1\\\\\rm A = 300(1.06)\\\\\rm A = \$318[/tex]
After 2 year:
[tex]\rm A= 300(1+0.06)^2\\\\\rm A = 300(1.06)^2\\\\\rm A = \$337.08[/tex]
Thus, the amount $300 after 1 year and after 2 year become $318 and $337.08 respectively.

The average newborn baby weighs 7.0 pounds, give or take 1 pound. The average newborn hippopotamus weighs 40 pounds, give or take 1 pound. Which statement is true about the percent error of each of the two newborns?
a. A newborn baby has a smaller percent error
b. A newborn hippopotamus has a smaller percent error
c. Both newborns have the same percent error
d. There is not enough information to decide
Answer:
B
Step-by-step explanation:
since the average newborn hippopotamus has a larger weight, if you give or take one pound, the percent error will not make as much of a difference as it would with the weight of an average newborn baby (7 pounds). therefore, a newborn hippopotamus has a smaller percent error.

3.56
Step-by-step explanation:
The vertex of a parabola is (-1, -8) and the zeros are (-5, 3) Determine the equation of the parabola in standard and factored form
Answer:
Part A
The equation of the parabola in standard form is f(x) = 0.5·x² + x - 7.5
Part B
The equation of the parabola in factored form is f(x) = 0.5·(x + 5)·(x - 3)
Step-by-step explanation:
The coordinates of the vertex of the parabola, (h, k) = (-1, -8)
The zeros of the parabola = -5, 3
Part A
The quadratic equation representing the parabola can be written as follows;
y = a·(x - h)² + k
The standard form of the equation is f(x) = a·x² + b·x + c
k = c - b²/(4·a)
h = -b/(2·a)
c = k + a·h² = -8 + a
From the zeros of the parabola, we have;
f(-5) = a × (-5)² + b×(-5) + c = 25·a - 5·b + c = 0
f(3) = a × (3)² + b×(3) + c = 9·a + 3·b + c = 0
Therefore, we have;
25·a - 5·b + c = 0...(1)
9·a + 3·b + c = 0...(2)
From which we have;
25·a - 5·b + c = 25·a - 5·b - 8 + a = 26·a - 5·b - 8 = 0
9·a + 3·b + c = 9·a + 3·b - 8 + a = 10·a + 3·b - 8 = 0
We then have;
26·a - 5·b = 8...(3)
10·a + 3·b = 8...(4)
Making 'b', the subject of both equations (3) and (4), equating the values, we find the value of 'a' as follows;
From equation (3), we have;
26·a - 5·b = 8
∴ b = (26·a - 8)/5
From equation (4), we have;
10·a + 3·b = 8
∴ b = (8 - 10·a)/3
From b = b, by transitive property, we have;
(26·a - 8)/5 = (8 - 10·a)/3
3 × (26·a - 8) = 5 × (8 - 10·a)
78·a - 24 = 40 - 50·a
∴ 128·a = 64
a = 64/128 = 1/2 = 0.5
a = 0.5
∴ b = (26·a - 8)/5 = (26 × 0.5 - 8)/5 = (13 - 8)/5 = 1
b = 1
c = -8 + a
∴ c = -8 + 0.5 = -7.5
c = -7.5
The equation of the parabola in standard form is therefore presented as follows;
f(x) = 0.5·x² + x - 7.5
Part B
The equation of the parabola in factored form is given as follows;
With the aid of a graphing calculator, we have;
f(x) = 0.5·x² + x - 7.5 = 0.5×(x² + 2·x - 15) = 0.5·(x + 5)·(x - 3)
The equation of the parabola in factored form is f(x) = 0.5·(x + 5)·(x - 3)

Answer:
∠A = 60°
∠B = 42°
∠C = 78°
Step-by-step explanation:
∵ In a triangle, sum of all the three interior angles is 180°
∴ m∠A + m∠B + m∠C = 180°
∴ (4x)° + (3x - 3)° + (5x + 3)° = 180°
∴ (4x + 3x - 3 + 5x + 3)° = 180°
∴ (12x)° = 180°
∴ 12x = 180
∴ x = 180/12
∴ x = 15
∠A = (4x)° = (4× 15)° = 60°
∠B = (3x-3)° = (3× 15-3)° =(45-3)°= 42°
∠C = (5x+3)° = (5× 15 + 3)° =(75 + 3)°= 78°

Consider the figure shown below. How long is HG?
Answer:
HG = 2[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° = [tex]\frac{1}{2}[/tex] , then
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{GI}{HG}[/tex] = [tex]\frac{\sqrt{2} }{HG}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
HG = 2[tex]\sqrt{2}[/tex]
Use trigonometry.
Angle H = 30 degrees
sin (30) = sqrt{2}/HG
HG = sqrt{2}/sin (30)
HG = 2.8284271248
HG = 2•sqrt{2}
