Answer:
(1,2)
Step-by-step explanation:
P is (-2,1) and it says you have to rotate it 90 degrees clockwise so that means you make the X opposite which makes it (2,1) and then you have to switch the x and y so that makes your final answer (1,2)
If the legs of a right triangle are x, (2x - 1) and its hypotenuse is (2x + 1), what is the value of x?
Answer:
x=8
Step-by-step explanation:
(2x + 1)² = x² + (2x - 1)² = x² + (2x - 1)(2x - 1)
(2x + 1)(2x + 1) = x² + 4x²-2x-2x+1
4x²+2x+2x+1 = 5x²-4x+1
4x²+4x+1 = 5x²-4x+1
0= 5x²-4x²-4x-4x+1-1
0= x²-8x
x²-8x=0
x²=8x
x=8

A penny is about 5×10−3 feet thick. The One World Trade Center building is about 2,000 feet tall. How many pennies would be in a stack of pennies as tall as the One World Trade Center building?
Answer:
400000 pennies
Step-by-step explanation:
A penny is about 5×10^-3 feet thick. The One World Trade Center building is about 2,000 feet tall.
The number of pennies that would be in a stack of pennies as tall as the One World Trade Center building is calculated as:
Height of the building ÷ Thickness of a penny
Height of the building = 2000 feet
Thickness of a penny = 5 × 10^-3 feet
Hence:
= 2000feet/ 5 × 10^-3 feet
= 400000 pennies
The ratio of lemons to lime in a punch is 6:4. If there are 35 fruit in the punch, how many of them are lemons?
Answer:
21 lemons
Step-by-step explanation:
If the ratio is 6:4, the ratio is also equal to 3:2. This means, for every 3 lemons, there are two limes.
So, if there are 35 lemons and limes in total, we would have 21 lemons and 14 limes.

The fraction white is one third.
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
With 12 of them red and 4 of them navy, it's 12 + 4 = 16 leaving 8, 24 - 16 = 8 and 8 goes into 24 three times so it'd be 1/3 simplified
Suppose that a phone that originally sold for $800 and is worth 3/5 of its value each year after it is released. Write an equation for the value of the phone, y years after it is released.
Answer:
v = 800 - 3/5y
Step-by-step explanation:
v = value
y = years
The original cost/value was 800 dollars which means you would have to subtract the 3/5 decrease in value each year.
v = 800 - 3/5y
Answer:
800/(y*3/5)

Given f(x) = x ^ 2 - (3x + 8) Find f(1)
Answer:this problem requires one to plug in the value given to the equation given. to find f(-1) the x in one side of the equation is replaced by a -1 therefore the x in the other side of the equation must also be replaced by (-1) so the answer is -3(-1) -8 = f(-1) = -5. -5 is the correct answer.

Construct the bisector of the following figures
Answer:
In these lessons, we will learn
how to construct an angle bisector of a given angle.
how to use an angle bisector to construct some angles for example, 90 degrees, 45 degrees, 60 degrees, 30 degrees, 120 degrees, 135 degrees, 15 degrees.
An angle bisector is a straight line that divides the angle into two equal parts.
Example: Construct an angle bisector for the following angle:
Solution:
Step 1 : Put the sharp end of your compasses at point B and make one arc on the line BC (point S) and another arc on line AB (point T).
Step 2 : Put the sharp end of the compasses at S and make an arc within the lines AB and BC. Do the same at T and make sure that the second arc intersects the first arc.
construct angle bisector
Step 3 : Draw a line from point B to the points of intersection of the 2 arcs. This line bisects ∠ABC.
construct angle bisector
The steps to construct an angle bisector can be summarized as follows:
1. From the vertex, draw an arc across both rays of the angle.
2. From each arc intersection draw another pair of arcs that intersect each other.
3. Draw a line from the vertex to the intersection point to form the angle bisector.

At one store, a 2-liter bottle of soda costs $2.12. At another store, a 3-liter bottle costs $3.15. Which bottle is a better deal? Write a division equation for each 2-liter bottle, and then decide which is the better deal.
Answer:
The 3 liter bottle has a better deal
Step-by-step explanation:
Which bottle is a better deal?
For the 2 liter bottle
At one store, a 2-liter bottle of soda costs $2.12.
2 liter bottle = $2.12
1 liter bottle = x
Cross Multiply
2x = $2.12
x = $2.12/2
x = $1.06
Hence, this is $1.06 per liter
For the 3 liter bottle
At another store, a 3-liter bottle costs $3.15.
3 liter bottle = $3.15
1 liter bottle = x
Cross Multiply
3x = $3.15
x = $3.15/3
x = $1.05
Hence, this is $1.05 per liter
Therefore, the bottle which is a better deal is the 3 liter bottle because, 1 liter goes for $1.05
Write the equation of an exponential function that satisfies these characteristics:
1. y intercept of (0,5)
2. range is all y values greater than 0
The value of the exponential equation is y = 5ˣ + 4
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
The y intercept is ( 0 , 5 )
So , when x = 0 , the value of y = 5
Substituting the values in the equation , we get
y = 5ˣ + 4 be equation (1)
when x = 0
y = 5⁰ + 4
y = 1 + 4
y = 5
when x = 2
y = 5² + 4
y = 25 + 4 = 29
Therefore , the range is all y values greater than 0
Hence , the equation is y = 5ˣ + 4
