Answer:
Step-by-step explanation:
only d can be correct,but not always.
let s=√8 (irrational)
t=√2 (irrational)
s/t=√8/√2=√(4×2)/√2=2√2/√2=2 (rational)
so d is true.
again take another example
let s=π (irrational)
t=√2
s/t=π/√2 (irrational)
d is not true.

Answer:
AB ≈ 5.39
Step-by-step explanation:
If you draw a line down from A, and another line left from B, the lines will intersect to form a right triangle with AB as the hypotenuse. You can use the Pythagorean theorem to find the length AB.
The vertical leg is 2 grid squares (units) long. The horizontal leg is 5 grid squares (units) long.
Then the hypotenuse, AB, is ...
AB = √(2² +5²) = √(4 +25) = √29
AB ≈ 5.39
The length of AB is about 5.39 units.

what is the measure of an angle that is supplementary to 20 degrees?
Answer: Sum of 180˚
Step-by-step explanation:
Hence, the supplement of a 20˚ angle is a 160˚ angle. This can be proven again, since 20+160=180 , and supplementary angles have a sum of 180˚ .

Write and solve an inequality for the situation. Tom is deciding whether he should become a member of a gym to use the basketball courts. The membership costs $135. Then, members will pay $3 each time they rent out the courts. Nonmembers can also rent the courts for $11 each time. How many times would Tom have to rent the basketball courts in order for his cost as a member to be cheaper than the cost of a nonmember? As a member, Tom's cost would be cheaper if he rents the courts or more times.
Answer:
As a member, Tom's cost would be cheaper if he rents the courts 17 or more times.
Step-by-step explanation:
Let the number of times be x
If Tom is a member, and rents the courts x number of times, then he would pay
$135 + $3 × x = $135 + $3x
For a nonmember that rents x number of times, the nonmember would pay
$11 × x = $11x
Now, we are to determine which value of x for which $135 + $3x is less than $11x, that is
$135 + $3x < $11x
Solving the inequality,
$135 < $11x - $3x
$135 < $8x
$135 / $8 < x
16.875 < x
∴ x > 16.875
This means, for Tom's cost to be cheaper, he must have rented the court for more than 16.875 times. (Round 16.875 to the nearest whole number)
16.875 ≅ 17
∴ x > 17
Hence, As a member, Tom's cost would be cheaper if he rents the courts 17 or more times.

A jeweler states that she makes a 20% profit over her expensive for making gold necklaces. If she sells each necklace for $600 how much does it cost her to make each necklace
Answer:
480
Step-by-step explanation:
The cost of each for manufacturing necklace is $500.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
Let's say the cost of one necklace is x dollars.
Now,
Profit percentage = (selling price - cost) / cost × 100
20% = (600 - x) / x × 100
600 - x = 0.2x
0.2x + x = 600
1.2x = 600
x = 500
Hence "The cost of each manufacturing necklace is $500".

An investment of $8,350 earns 5.2% interest compounded monthly over 10 years. Approximately how much interest is
earned on the investment?
a.
$4,342
b $5,513
$5,679
d $13,863
$5,679.16 interest is earned on the investment
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
P = $8,350 the principal (the money deposited)
r = 0.052 or 5.2% annual interest rate
t = 10 years
m = 12 compounding period per year
i = r/m = 0.052/12 = 0.013/3 interest rate per period
n = t×m = 10×12 = 120 total number of compounding periods
A = future value
A = P(1 + i)ⁿ
A = 8350(1 + 0.013/3)¹²⁰
A = $14,029.16
I = A - P
I = 14029.16 - 8350
I = $5,679.16
there are $5,679.16 interest earned on the investment.
Hence, $5,679.16 interest is earned on the investment

A model rollercoaster is built to a scale of 1:32. In the model rollercoaster, the angle between the ground and the steepest slope is 110°. What is the angle between the ground and steepest slope on the real rollercoaster?
The angle between the ground and the steepest slope on the real rollercoaster is approximately 89.998°.
A model rollercoaster is built to a scale of 1:32. In the model rollercoaster, the angle between the ground and the steepest slope is 110°.What is the angle between the ground and the steepest slope on the real rollercoaster?
To determine the angle between the ground and the steepest slope on the real rollercoaster, you need to consider the scale of the model rollercoaster.To find the real rollercoaster angle, you should use a scale factor that relates the model rollercoaster to the real one.
The scale factor should multiply the model angle to obtain the real one. Since the scale factor relates the model length to the real length, it should relate the horizontal distance and the vertical height.
The horizontal and vertical lengths are in a ratio of 32:1 for the model. This means that for every 32 units in the model, there is one unit in the real rollercoaster. Therefore, we can say that the horizontal length of the real rollercoaster is 32 times the horizontal length of the model rollercoaster.
That is:h(real) = 32h(model)Similarly, the vertical height of the real rollercoaster is 32 times the vertical height of the model rollercoaster. That is:v(real) = 32v(model)
The tangent of an angle equals the vertical height divided by the horizontal distance. Therefore, the tangent of the real angle equals the tangent of the model angle times the scale factor.
That is:tanθ(real) = 32tanθ(model)By substitution,θ(real) = arctan(32tanθ(model))For the given model angle of 110°,
the corresponding real angle is:θ(real) = arctan(32tan110°)θ(real) = arctan(32(-2.74747741945462))θ(real) = arctan(-87.91927694142864)θ(real) ≈ -89.998°
The negative sign indicates that the angle is measured below the horizontal line.

Solve for x.
5 = 3x - 3
Answer:
x = 8/3
Step-by-step explanation:
Step 1: Write equation
5 = 3x - 3
Step 2: Solve for x
Add 3 to both sides: 8 = 3xDivide both sides by 3: 8/3 = xRewrite: x = 8/3Step 3: Check
Plug in x to verify it's a solution.
5 = 3(8/3) - 3
5 = 8 - 3
5 = 5
Answer:
x= [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
5=3x-3
first, add 3 to both sides:
5 +3 = 3x-3 +3
8=3x
then, divide both sides by 3:
8 ÷3 = 3x ÷3

Answer:
G'(y) = 4y^7(y+4)/(y+2)^5
Step-by-step explanation:
Work it a piece at a time.
Define z = y^2/(y+2). Then your derivative is found from the power rule as ...
G = z^4
G' = 4z^3·z'
Now, define z = u/v. Then your derivative is found using the quotient rule:
z' = (vu' -uv')/v^2 = ((y+2)(2y) -(y^2)(1))/(y+2)^2
Putting this together we have ...
[tex]G'(y)=4\left(\dfrac{y^2}{y+2}\right)^3\cdot\dfrac{y^2+4y}{(y+2)^2}\\\\\boxed{G'(y)=\dfrac{4y^8+16y^7}{(y+2)^5}}[/tex]
