Answer:
When rotating any polygon 90 degrees, each vertice/point of the polygon should be changed from (x, y) to (y, -x). Because of this, E(-7, -4) should be E'(-4, 7), F(-2, -1) should be F'(-1, 2), and G(-5, -8) should be G'(-8, 5) after the rotation.
Step-by-step explanation:
Like I explained above, when rotating a shape 90 degrees clockwise on a plane, the points change from (x, y) to (y, -x). The student changed each point from (x, y) to (-y, x), which is a 90 degree counterclockwise rotation. That is why the student is incorrect.
I hoped this helped! Sorry, I am terrible at explaining things. :)

Kelvin wants to know whether he skied without falling more than twice as long as anyone else in his family. His dad tells him that he can check by using the inequality 2f < 223, where f is the time skied in seconds for each person. Plug the values for the time skied by each person into the inequality to find the answer.

a single die is rolled. How many ways can you roll a number that is prime, followed by a 6?
Answer:
3 ways
Step-by-step explanation:
Since 6 will remain constant throughout the testing, we just need to find all prime numbers 1-6.
1 - is not prime nor composite
2 - is prime
3 - is prime
4 - 2x2=4, so composite
5 - is prime
6 - 2x3=6, so composite
Therefore, 2, 3, and 5 are prime numbers, and there are 3 of them.
Answer:
3 ways
Step-by-step explanation:
2 , 3 and 5 are prime numbers.
How do you subtract decimals? I need examples
Answer:
Examples: 0.9 - 0.3 = 0.6; 1.5 - 1.2 = 0.3, 10.8 - 5.3 = 5.5
Step-by-step explanation:
It's the same way of subtracting any regular number just line up the two numbers based on the position of the decimals. Then subtract them, then put the decimal in the position where you have originally lined up to be in the new number.
Look at the diagram I posted for the example!

a 20 inch rod fits perfectly in a box 15 inches tall what is the measurment of x in the diagram round to the nearest tenth
The 20-inch rod forms a right triangle with the 15 inches tall box
The value of x in the diagram is 13.2 inches
How to determine the value of xTo calculate the value of x, we make use of the following Pythagoras theorem
[tex]20^2 = 15^2 + x^2[/tex]
Evaluate the exponents in the above equation
[tex]400 = 225 + x^2[/tex]
Subtract 225 from both sides of the equation
[tex]175 = x^2[/tex]
Take the square root of both sides
[tex]x = 13.2[/tex]
Hence, the value of x in the diagram is 13.2 inches

Find the value of x.
Answer:
x = 24
Step-by-step explanation:
A triangle has a total of 180 degrees as its inner angle measurement.
If you look at the bigger triangle, it has two out of three angles: 94 and 41.
Since we know the angle has to be 180, we can simply subtract the sum of 94 and 41. We get 45 degrees.
Now that we have that measurement, we look at the smaller triangle. The 45 degrees is shared both by the bigger one and the smaller one. Which gives us two out of three angles for the smaller one.
Again, add 111 and 45 and then subtract the result from 180. We get 24 degrees.

What is the diameter if the radius is 6ft?
Answer:
Step-by-step explanation:
The radius is approximately . 96 ft.
We will use the formula Circumference = 2pi(radius)
=> C=2pi(r)
=> Substitute 3.14 for pi, and 6 for C
=> 6 = 2(3.14)r
=> 6 = 6.28r
=> .955 =r
=> The radius is approximately .96 ft.

Answer:
[tex]x=-\frac{11}{18}[/tex]
Step-by-step explanation:
[tex]-1\frac{7}{9}=(-2\frac{5}{6} + \frac{1}{3})x[/tex]
Solve parenthesis first
[tex]-2\frac{5}{6} + 1/3[/tex]
Find a common denominator.
The common denominator would be 6.
Because the first expression already has a denominator of 6 it stays the same.
[tex]\frac{1}{3} = \frac{2}{6}[/tex]
[tex]-2\frac{5}{6} + \frac{2}{6} = -2\frac{7}{6} = -1\frac{1}{6}[/tex]
Put that into the original equation.
[tex]-1\frac{7}{9}=(-1\frac{1}{6} )x[/tex]
Isolate the x. Add [tex]1\frac{1}{6}[/tex] to each side.
[tex]-1\frac{7}{9}+ 1\frac{1}{6}=x[/tex]
Find a common denominator.
we can use 18 as the common denominator.
[tex]-1\frac{7}{9}+ 1\frac{1}{6}= -1 \frac{14}{18} +1\frac{3}{18}= x[/tex]
Add.
[tex]-\frac{11}{18} =x[/tex]
We cannot simplify so our answer stays the same.

If using the method of completing the square to solve the quadratics equation x^2+15x+34
Answer:
Factoring x2-15x-34
The first term is, x2 its coefficient is 1 .
The middle term is, -15x its coefficient is -15 .
The last term, "the constant", is -34
Step-1 : Multiply the coefficient of the first term by the constant 1 • -34 = -34
Step-2 : Find two factors of -34 whose sum equals the coefficient of the middle term, which is -15 .
-34 + 1 = -33
-17 + 2 = -15 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -17 and 2
x2 - 17x + 2x - 34
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-17)
Add up the last 2 terms, pulling out common factors :
2 • (x-17)
Step-5 : Add up the four terms of step 4 :
(x+2) • (x-17)

Do not round any intermediate computations, and round your answer to the nearest cent.
Answer:
$3,135.42
Step-by-step explanation:
[tex]p{e}^{.055 \times 2} = 3500[/tex]
[tex]p = \frac{3500}{ {e}^{.11} } = 3135.42[/tex]
The person should invest $3135.42 at an interest rate of 5.5% compounded continuously to have $3500 in two years.
What is continuous compounding?The practice of continuous compounding involves computing interest and reinvesting it into the balance of an account for an endless number of periods.
Given that, the interest rate is n = 5.5%comp continuously and the final amount after x = 2 years is P(x) = $3500.
The formula for the final amount in continuous compounding is:
P(x) = P₀eⁿˣ (1)
Where P(x) is the amount after x years, P₀ is the initial amount, and n is the interest rate.
Substitute the values into equation (1):
[tex]3500 = P_{0}e^{5.5\%(2)}\\\\p_{0}=\frac{3500}{e^{0.11}}\\\\P_0=3135.42[/tex]
Hence, the person should invest $3135.42 at an interest rate of 5.5% compounded continuously to have $3500 in two years.
