PLEASE HELP!!!!The point (−2,−3) is rotated 90 degrees counterclockwise using center (0,0) . What are the coordinates of the image?
a (3,−2)
b (−3,2)
c (−3,−2)
(d 3,2)
Answer: a 3,-2
Step-by-step explanation:
When a point is rotated, it must be rotated around a center.
The coordinate of the image of (-2,-3) is (3,-2)
The point is given as:
[tex](x,y) = (-2,-3)[/tex]
The rule of 90 degrees counterclockwise rotation is:
[tex](x,y) \to (-y,x)[/tex]
So, we have:
[tex](-2,-3) \to (3,-2)[/tex]
Hence, the coordinate of the image of (-2,-3) is (a) (3,-2)

the length of a rectangle is 8 feet more its width.the area of the rectangle is 84 square feet find its length and width
Answer:
length=8+w........1
area=84square feet........2
area of rectangle =length x width
area=(8+w)x W
area=8w+w^2
84=8w+w^2
w^2+8w+(4^2)=84+(4^2)
(w+4)^2=84+16
(w+4)^2=100
√(w+4)^2=√100
w+4=±100
w+4=100 or w+4=-100

Together, teammates Pedro and Ricky got 2687 base hits last season. Pedro had 283 more hits than Ricky. How many hits did each player have?
Answer:
Ricky hits 1202 base
Pedro hits = 1485 base
Step-by-step explanation:
Pedro + Ricky = 2687 hits
Let Ricky hits = x
So the Pedro hits will be = x + 283
( x + 283 ) + x = 2687
2 x + 283 = 2687
2 x = 2687 - 283
2 x = 2404
x = 1202
So the Ricky hits 1202 base
Pedro hits (1202 + 283) = 1485 base
Final answer:
To determine the number of hits Ricky and Pedro had, a system of equations was set up and solved. Ricky had 1202 hits, while Pedro had 1485 hits last season.
Explanation:
To solve the problem involving teammates Pedro and Ricky's base hits, we need to set up a system of equations based on the information given:
Pedro and Ricky's hits together total 2687.
Pedro had 283 more hits than Ricky.
Let's denote Ricky's hits as R and Pedro's hits as P. The two equations representing the situation are:
R + P = 2687
P = R + 283
To find the number of hits Ricky had, we can substitute the second equation into the first:
R + (R + 283) = 2687
2R + 283 = 2687
2R = 2687 - 283
2R = 2404
R = 2404 / 2
R = 1202
Now that we have Ricky's hits, we can find Pedro's hits by adding 283 to Ricky's total:
P = R + 283
P = 1202 + 283
P = 1485
Therefore, Ricky had 1202 hits, and Pedro had 1485 hits last season.

Let the population of a city be 1,006,150 people. What is the least number of people that share a birthday?
Answer:
The least number of people that share a birthday is 1, no matter what the size of the population is.
Step-by-step explanation:
Tricky Question
Suppose there is one person that has their birthday on Feb 02. It's perfectly possible that no one else in the city has their birthday on the same day, i.e. their birthdays are any time except Feb 02. So that person will be the only one who has that as a birthday. It's even possible that no one has a birthday on Feb 02, so the answer will be zero, but it's not possible to talk about sharing if no one is doing it, so the answer is
The least number of people that share a birthday is 1, no matter what the size of the population is.
Note: If this question is talking about probability calculations, then the matter is totally different.
sum of money is placed at simple interest for 3 years at 10% per annum and then the amount is invested for 2 years at the same rate at compound interest . If the total amount of 5 years became Rs. 471900, what was the sum?
Answer:
sum was 300000
Step-by-step explanation:
let sum of money is placed is x rs
Term T = 3 years, rate R = 10%
Then simple interest for for 3 years is
[tex]SI= \frac{PTR}{100}\\ SI=\frac{x\times 3\times 10}{100} \\SI = 0.3x[/tex]
Sum of x will become x+0.3x = 1.3x after 3 years. now this 1.3x is kept for compound interest for two years. ie
[tex]A =P[1+R]^t\\471900=1.3x[1+\frac{10}{100} ]^2\\x=\frac{471900}{1.573} \\x=300000[/tex]
Sum was 300000
At the simple interest rate, the rate is applied only to the initial sum, while
at the compound interest, the rate is applied to the amount in the account.
The sum of money is approximately Rs 355,847.466Reasons:
Let P represent the sum of money invested, we have;
[tex](P + P \cdot r \cdot t_1) \times (1 + r)^{t_2} = \mathbf{ 471900}[/tex]Where;
P = The initial sum invested
r = The simple and compound interest rate applied = 10% = 0.1
t₁ = The number of years the money is placed at simple interest = 3 years
t₂ = The number of years the money is placed at compound interest = 2 years
Therefore;
[tex]\mathbf{(P + P \times 0.1 \times 3) \times (1 + 0.01)^{2}} = 471900[/tex]
Which gives;
[tex]P \cdot (1 + 0.3 ) \times (1 .01)^{2} = 471900[/tex]
[tex]\displaystyle P =\mathbf{\frac{471900}{(1 + 0.3 ) \times (1 .01)^{2} }} \approx 355,847.466[/tex]
The sum of money invested, P ≈ Rs 355,847.466

suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Write an equation for the water level ,L ,after D days . In how any days will the water level be 26 feet
Equation: L= -0.5D+34.
The water level be 26 feet in 16 days.
Step-by-step explanation:
Let us consider the initial level (x=0) of the water is 34 feet. Then its coordinate point can be written as (0,34).
The water is receding at the rate 0.5 feet per day, which given us the information that 0.5 is the slope since it is the rate of change and it is decreasing so it is a negative slope.
⇒m= -0.5.
The line equation is y = mx+c. Let us rewrite as L= mD+c.
Where L is the level of water(y-axis) and D is the days(x-axis) and c is y-intercept.
⇒L= (-0.5)D+c.
To find y-intercept, substitute (0,34) (the known point from the graph) in the equation. Also, the point in y axis when x=0 is y-intercept.
34= (-0.5)(0)+c.
c=34.
∴L= (-0.5)D+34.
To find the days when the water achieves level as 26 feet:
26 = (-0.5)D+34.
26-34= (-0.5)D.
-8 = (-0.5)D.
D= [tex]\frac{-8}{-0.5}[/tex].
D= 16.

(1) The numbers are 8 and 16.
(2) John have 12 nickels and 6 dimes.
Solution:
(1) Let x and y be the two numbers.
Sum of two numbers = 24
⇒ x + y = 24 – – – – (1)
One number = Other number – 8
⇒ x = y – 8 – – – – (2)
Substitute equation (2) in equation (1), we get
⇒ y – 8 + y = 24
⇒ 2y – 8 = 24
Add 8 on both side of the equation, we get
⇒ 2y = 32
Divide by 2 on both sides.
⇒ y = 16
Substitute y = 16 in equation (2)
⇒ x = 16 – 8
⇒ x = 8
Hence the numbers are 8 and 16.
(2) Let n and d be the nickels and dimes respectively.
Nickels + Dimes = 18
⇒ n + d = 18 – – – – (1)
Nickles = Dimes + 6
⇒ n = d + 6 – – – – (2)
Substitute equation (2) in equation (1), we get
⇒ d + 6 + d = 18
⇒ 2d + 6 = 18
Subtract 6 from both side of the equation.
⇒ 2d = 12
Divide by 2 on both side of the equation, we get
⇒ d = 6
Substitute d = 6 in equation (1), we get
⇒ n = 6 + 6
⇒ n = 12
Hence John have 12 nickels and 6 dimes.

Which ordered pair (x,y) makes this relation a function?
{(2,3), (–2,5), (4,4), (-4,5), (x,y)}
A. (-4, -1)
B. (-1,-1)
C. (-2,-1)
D. (2, -1)
Answer:
Step-by-step explanation:
A i think sorry if it is wrong
The only ordered pair that can be added to make the relation a function, without repeating an x-value, is option B. (-1,-1).
The question is asking which ordered pair (x,y) makes the given set of ordered pairs a function. A function is defined as a relation where every x-value (input) is associated with exactly one y-value (output). We already have the points (2,3), (–2,5), (4,4), and (-4,5) in our set. To maintain the definition of a function, the x-value of the ordered pair we are going to add cannot be the same as any x-value already present in the set. Looking at our options:
A. (-4, -1) - This would not work because the x-value -4 is already paired with the y-value 5 in our set.B. (-1,-1) - This is a possibility as the x-value -1 is not in the set.C. (-2,-1) - This would not work because the x-value -2 is already paired with the y-value 5 in our set.D. (2, -1) - This would not work because the x-value 2 is already paired with the y-value 3 in our set.Therefore, the only ordered pair that makes the relation a function is option B. (-1,-1).

find the length of the orther leg when one leg is 20 and hypotenous is 25
Answer:
15
Step-by-step explanation:
Do 25 ^ 2 = 625
Do 20 ^ 2 = 400
Because you're finding something that's nor the hypotenuse you subtract
So you do 625 - 400 = 225
Then you do the square root of 225 to get the answer
Which is 15
Answer:
15
Step-by-step explanation:
Let 'l' be the length of the other leg
Using pythagoras theorem,
25² = 20² + l²
625 = 400 + l²
225 = l²
l = 15
