Answer:
40.5
Step-by-step explanation:
if y varies jointly as the square of x and the cube of z and inversely as the square root of w, this is expressed as;
y ∝ x²z³/√w
y = kx²z³/√w
If x = 2, z = 2, y = 12 and w = 64
Substitute;
12 = k (2)²(2)³/√64
12 = 32k/8
12 = 4k
k = 12/4
k = 3
To get y when x = 1, z = 3, and w = 4.
y = 3 (1)²(3)³/√4
y = (3*27)/2
y = 81/2
y = 40.5
Hence the value of y is 40.5

If Q is the midpoint between P and R, PQ = 3x + 2 and QR = 7x - 18, find the value of x.
Answer:
x = 5
Step-by-step explanation:
Since Q is the midpoint of PR,
PQ = QR
=> 3x + 2 = 7x - 18
=> 3x - 7x = -18 - 2
=> -4x = -20
=> x = -20/-4
=> x = 5

Answer:
[tex]\frac{f(x+h)-f(x)}{h}[/tex][tex]=2x - h[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 8 - x^2[/tex]
Required
Determine: [tex]\frac{f(x+h)-f(x)}{h}[/tex]
First, we calculate f(x + h)
[tex]f(x) = 8 - x^2[/tex]
[tex]f(x+h) = 8 - (x+h)^2[/tex]
[tex]f(x+h) =8- x^2-2xh-h^2[/tex]
So, we have:
[tex]\frac{f(x+h)-f(x)}{h}[/tex] [tex]= \frac{8- x^2-2xh-h^2 - 8 + x^2}{h}[/tex]
[tex]\frac{f(x+h)-f(x)}{h}[/tex] [tex]= \frac{8 - 8 + x^2- x^2-2xh-h^2}{h}[/tex]
[tex]\frac{f(x+h)-f(x)}{h}[/tex] [tex]= \frac{-2xh-h^2}{h}[/tex]
[tex]\frac{f(x+h)-f(x)}{h}[/tex][tex]=2x - h[/tex]
I want to withdraw 400.00 for 9 years at 8%. How much do I need to deposit
Answer:
The principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.
Step-by-step explanation:
Given
Total accrued Amount A = 400.00 (Let say $)Time period t = 9 yearsInterest rate r = 8% = 0.08To determine
Principle P = ?
Using the formula
P = A / (1 + rt)
substituting A = 400.00, t = 9 and r = 0.08 in the formula
P = 400 / ( 1 + (0.08 × 9))
P = $232.56
Therefore, the principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.

An elementary school wants to purchase a new swing set. The table shows the selling price of the swing sets they are interested in buying
Swing Set
Wholesale Price ($)
Adventurers
3,056
Thunder Ridge
4,125
The markup for both swing sets is 20%. The school decides to buy the Adventurers swing set. What is the selling price of the swing set they
are buying? Round to the nearest cent if necessary,
Answer: The answer is 3674.84
The selling price of Adventurers swing set is $3,667
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
Example:
50% = 50/100 = 1/2
We have,
Adventurers swing set wholesale selling price = $3056
Markup means the amount increased.
20% Mark up on the price:
= 20% of 3056
= 20/100 x 3056
= $611.2
The selling price of Adventurers swing set:
= $3056 + $611.2
= $3,667.2
Rounding to the nearest cent:
= $3,667
Thus the selling price of Adventurers swing set is $3,667

P
is
−

, and
P
is in quadrant IV , then
If the y-coordinate of P is −3/5, and P is in quadrant IV, then x = 4/5
How to find the coordinate of a unit circle?
In Trigonometry, the unit circle is a special circle that is centered on the origin of a coordinate grid, with a radius equal to 1 unit.
Now, we are told that the point P is on the unit circle and also we know that the length of the line from P to the origin is exactly 1 unit.
We're also given a y-coordinate as, y = -3/5.
The y-coordinate denotes the length of a perpendicular line from point P to the x-axis.
If x is the x-coordinate, y is the y-coordinate, and h is the hypotenuse length, we can set up the equation vis Pythagoras theorem as:
x² + y² = h²
Making x the subject gives;
x = √(h² – y²)
Plug in the relevant values h = 1 and y = -3/5 to get;
x = √(1)² – (-3/5)²
x = √1 – 9/25
x = √16/25
x = 4/5
We are told that P is in quadrant IV, which has negative values for both y and positive values for x and as such x is positive.
Thus, x = 4/5

4y + 4 = 2y - 10
Step 2: Solve for y
[Subtraction Property of Equality] Subtract 2y on both sides: 2y + 4 = -10[Subtraction Property of Equality] Subtract 4 on both sides: 2y = -14[Division Property of Equality] Divide 2 on both sides: y = -7Answer:
[tex]y = - 7[/tex]
Step-by-step explanation:
1. Subtract 2y from both sides.
[tex]4y + 4 - 2y = - 10[/tex]
2. Simplify 4y + 4 - 2y to 2y + 4.
[tex]2y + 4 = - 10[/tex]
3. Subtract 4 from both sides.
[tex]2y = - 10 - 4[/tex]
4. Simplify -10 - 4 to -14.
[tex]2y = - 14[/tex]
5. Divide both sides by 2.
[tex]y = - \frac{14}{2} [/tex]
6. Simplify 14/2 to to 7.
