Answer: [tex]\frac{1}{9}[/tex]
Step-by-step explanation:
When any number has a negative exponent, all the negative exponent is doing is flipping the sides.
When we plug -3 in for x we get [tex]-3^{-2}[/tex].
Now just imagine the -3 in fraction form as [tex]\frac{-3}{1}[/tex]. And all you do now is just flip the sides to get [tex](\frac{1}{-3} )^{2}[/tex]
And now apply the exponent 2 to the 1 and negative 3.
1 to the power of 2 is just 1
-3 to the power of 2 is 9.
So your answer is [tex]\frac{1}{9}[/tex]

A map is drawn to a scale of 1:50000.The distance between long mountain and plaine des papayes is 17.5 cm on the map.find the actual distance in km.
Answer:
8.75 km.
Step-by-step explanation:
You can set up a ratio of the map to the actual distance of [tex]\frac{1}{50000}[/tex].
Then, this ratio can be used to cross multiply and divide to get an equivalent ratio for the distance:
[tex]\frac{1}{50000}[/tex]=[tex]\frac{17.5 cm}{x cm}[/tex] By cross-multiplying we have x (in centimeters) = 17.5×50000. This tells us that x = 875,000 cm.
However, the answer asks for the distance in kilometers, so we need to convert it. There are 100,000 centimeters in a kilometer, so by dividing: 875000÷100000=8.75 kilometers.

The fletcher family puts loose change into a jar every evening. Once a month, the family counts the coins and prepares to take it to the bank, but removes all the pennies first. Last month, they found there were 14 more quarters than dimes, and the number of nickels was 8 less than 4 times the number of dimes. If the total value of the nickels, dimes, and quarters was $15.75, how many dimes did they have?
Answer:
They have 23 dimes
Step-by-step explanation:
Let x be the number of dimes
1 dime = 0.1 dollar
x dimes = 0.1x dollars
They found there were 14 more quarters than dimes.
No. of quarters = x+14
1 quarter = 0.25 dollar
(x+14) quarter =0.25 (x+14)
The number of nickels was 8 less than 4 times the number of dimes.
So, No. of nickels= 4x-8
1 nickel = 0.05 dollar
(4x-8) nickel = 0.05(4x-8) dollar
The total value of the nickels, dimes, and quarters was $15.75.
So,0.1x+0.25 (x+14)+ 0.05(4x-8)=15.75
x=23
Hence they have 23 dimes
A 2-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is labeled f (x) with entries 0.2, 0.4, 0.8, 1.6, 3.2. Which exponential function is represented by the table?
Answer:
D.
Step-by-step explanation:
The exponential function is represented by the table is,
f(x)=0.8(2^x).
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
The first column is labeled x with entries negative 2, negative 1, 0, 1, 2.
The second column is labeled f (x) with entries 0.2, 0.4, 0.8, 1.6, 3.2.

In a certain Algebra 2 class of 27 students, 5 of them play basketball and 12 of them
play baseball. There are 2 students who play both sports. What is the probability that
a student chosen randomly from the class plays basketball or baseball?
The probability that a student chosen randomly from the class plays basketball or baseball is 0.56.
We are able to utilize the equation:
P(B or b) = P(B) + P(b) - P(B and b)
where
B speaks to playing ball
and b speaks about playing baseball.
From the given data, we have:
P(B) = 5/27 (the likelihood of playing ball)
P(b) = 12/27 (the likelihood of playing baseball)
P(B and b) = 2/27 (the likelihood of playing both sports)
Substituting these values into the equation, we get:
P(B or b) = P(B) + P(b) - P(B and b)
= 5/27 + 12/27 - 2/27
= 15/27
= 5/9
Hence, the likelihood that an understudy chosen haphazardly from the course plays ball or baseball is 5/9 or around 0.56.

plzzzzz help x_4x+4 = 0
Answer:
x = -1
Step-by-step explanation:
4x + 4 = 0
Subtract 4 on both sides.
4x = 0 - 4
4x = -4
Divide both sides by 4.
x = -4/4
x = -1
Answer:
So the value of x is -1
Step-by-step explanation:
4x+4=0
Subtracting 4 on both sides
4x+4-4=0-4
4x=-4
Dividing 4 on both sides
x=-4/4
x=-1
find the size of angle yzx give your answer to 3 significant figures 7.5cm and 22.3cm
Answer:19.7
Step-by-step explanation:
Sin‐(7.5/22.3) on your calculator
The answer to 3 significant figures is 19.7
Size of angle YZX for the given measurements of triangle YZX is equal to 19.651°( 3 significant figure).
What is an angle?" Angle is defined as when two rays meet at one point known as vertex."
Formula used
[tex]sin\theta = \frac{ opposite side }{Hypotenuse}[/tex]
According to the question,
As shown in the figure,
In triangle YXZ,
Angle X = 90 degrees
Opposite side to ∠YZX , XY = 7.7cm
Hypotenuse , ZY = 22.3 cm
Substitute the value in the formula to get the value of size of angle YZX,
[tex]sin YZX = \frac{XY}{ZY}[/tex]
⇒[tex]sin YZX = \frac{7.5}{22.3}[/tex]
⇒[tex]sin YZX = 0.3363[/tex]
⇒ [tex]YZX = sin^{-1} (0.3363)[/tex]
⇒∠YZX = 19.651°
Hence, size of angle YZX for the given measurements of triangle YZX is equal to 19.651°( 3 significant figure).

which number line represents the solution to the inequality
The origin is contained in the solution set for this system of inequalities
y< 2x + 4
y> -2x - 2
Select one:
O True
O False
Answer:
O True
Step-by-step explanation:
If we substitute (x, y) = (0, 0) into both inequalities, we have ...
0 < 2·0 +4 ⇒ 0 < 4 . . . true
0 > -2·0 -2 ⇒ 0 > -2 . . . true
The point (0, 0) satisfies both inequalities, so is contained in the solution set.
The wheels of a car are of radius 40cm each, if the car is travelling at a speed of 66km/h, find the number of revolutions made by each wheel in 20 minutes
Answer: Each wheel makes 437.5 revolutions in 20 mins
Step-by-step explanation:
Circumference = 2πr
Given that the radius is 40 cm
Circumference = 2π(40) = 80π cm
Find the distance traveled in 20 mins
Speed = 66 km/h
1 hour = 66 km
Rewrite hour into min
60 min = 66 km
1 min = 66 ÷ 60 = 1.1 km
Rewrite km in cm
1.1 km = 1.1 x 10,000 cm = 110,000 cm
Find the number of revolutions in 20 mins:
1 revolution = 80π cm
Number of revolution = 110,000 ÷ 80π = 437.5
How would you write 4n + 3 as a verbal expression
When we have a number that appears
right before a variable, it means multiplication.
So 4n means the same thing as 4 times a number.
Remember, n is a variable which is just a
letter that represents any number.
Since we are adding 3 to 4n, we can say
4 times a number increased by 3.
So 4n + 3 can be written as 4 times a number increased by 3.
The product is 4n, then the added +3.
4n + 3
4 × n + 3
So the verbal expression can be said as:
''The product of four times a number 'n' added with 3.''

Grace wants to attend University of Oklahoma. One year at University of Oklahoma costs approximately $20,000. She currently has $4,000 in savings. Grace has received a one-time grant of $1,000 and an annual academic scholarship for $4,000. She plans to enroll in the work study program that will pay $9,000 annually for part-time work. How much will Grace need to borrow in student loans in order to attend University of Oklahoma for 4 years?
Answer:
Grace needs to borrow $23,000 in students loan in order to attend University of Oklahoma for 4 years.
Step-by-step explanation:
Cost for one year at University of Oklahoma = $20,000
Cost for 4 years = 4 × $20,000 = $80,000
Total amount Grace would have in 4 years = $4,000 + $1,000 + ($4,000×4) + ($9,000×4) = $57,000
Amount she needs to borrow = $80,000 - $57,000 = $23,000
