Answer:
The average rate of change is -3.
Step-by-step explanation:
We are given the function:
[tex]f(x)=9-x^2[/tex]
And we want to find the average rate of change from x = 0 to x = 3.
In other words, we will compute the function at the two endpoints, and then find the slope of the line that crosses the two points.
For our first endpoint at x = 0, our function evaluates to:
[tex]f(0)=9-(0)^2=9[/tex]
So, our first point is (0, 9).
For our second endpoint at x = 3, our function evaluates to :
[tex]f(x)=9-(3)^2=0[/tex]
So, our second point is (3, 0).
Then by the slope formula, our average rate of change will be:
[tex]\displaystyle m=\frac{0-9}{3-0}=\frac{-9}{3}=-3[/tex]

A 43-foot ladder is leaning against a building and forms a 29.37° angle with the ground. How far away from the building is the base of the ladder? Round your answer to the nearest hundredth. 21.09 feet 24.20 feet 37.47 feet 49.34 feet
Answer:
37.47 feets
Step-by-step explanation:
Using trigonometry:
The distance of wall from base of ladder is (x) :
Cosine θ = adjacent / hypotenus
Length of ladder = hypotenus ; x = adjacent
Cos 29.37 = x / 43
x = 43 * cos 29.37
x = 43 * 0.8714707
x = 37.473241
x = 37.47
Answer:
37.47 feet

Which best describes the triangle?
Answer: acute and isosceles
Step-by-step explanation: Notice that the triangle shown here has no right angles and no obtuse angles, which means that all of the angles of the triangle are acute. When classifying triangles, if all of the angles of the triangle are acute, then the triangle is acute.
Now, notice that two sides of the triangle have the same length.
If two sides of a triangle have the same length,
then we say that the triangle is isosceles.
So this triangle is acute and isosceles.
it takes 2 painters 5 hours to finish painting a house. how long would it take to finish painting a house if there were 20 painters working at the same rate?
Answer:
2 2/9 hours
Step-by-step explanation:
Im pretty Sure Its Correct
20 painters will use 0.5 hours to paint the same house at the same rate it takes 2 painters 5 hours to finish the house.
Let's find how long it take:It takes 2 painters 5 hours to finish painting a house.
For 20 painters to paint the same work at the same rate, this means the time used to conclude the work will drastically reduced.
Therefore,
if 2 painters uses 5 hours
At the same rate, 20 painters will use = 2 × 5 / 20 = 10 / 20 = 1 / 2 = 0.5 hours.

A company has 2.4 times 10 to the 6th power shares of stock and 1.5 times the 10 to the 4th power shareholders. If each shareholder owned the same number of shares, how many shares would each shareholder own? Write your answer in scientific notation
Answer: 1.6 * 10² shares
Step-by-step explanation:
Number of shares company has = 2.4 * 10⁶
Number of shareholders = 1.5 * 10⁴
Number of shares each shareholder owns:
= 2.4 * 10⁶/1.5 * 10⁴
= 2.4/1.5 * 10⁶⁻⁴
= 1.6 * 10²

A bedroom garbage can weighed 3/4of a pound. A Bathroom garbage can weighed 1/4 of a pound. Which is more?
Answer:
The bedroom garbage
Step-by-step explanation:
since the denominators are same, we can compare the numerators. 3 is larger than 1 so it would be the bedroom garbage
Answer:
3/4 of a pound
Step-by-step explanation:
3/4 of a pound is 1/4 more than half a pound. 1/4 is less then half a pound. Half a pound is 2/4 or 1/2.
The difference between two numbers is 4. If the larger number is equal to wo more than three times the smaller number. What are the two numbers
Answer:
1 and 5
Step-by-step explanation:
s = smaller number
l = larger number = 2 + 3s
2 + 3s - 1s = 4
2 + 2s = 4
2s = 2
s = 1
l = 2 + 3(1)
l = 5

If a,b and c are the sides of a triangle
where a = 6, b = 8 and c = 9
is this a right triangle ?
Answer:
No, it is not a right triangleStep-by-step explanation:
A right triangle consists of hypotenuse, opposite and adjacent. For the sides to be a right angle, the r=square of the longest side (hypotenuse) must be equal to the sum of the square of the other two sides
Given the sides a = 6, b = 8 and c = 9
a²+ b² = c² (This equation must be satisfied)
Taking the sum of the square of a and b
6² + 8²
= 36 + 64
= 100
= 10²
Since the result is not the square of 9 which is the third side, hence the sides is not a right triangle

Step-by-step explanation: It has a total of 28 'x's so 28 x 50 = 1400
1400 divided by 7 ( Cause of the one week) is 200. if I figure out what the actual answer is I will tell you. Also be sure to read the comments.
Answer: The answer is the bottom one to the left
Step-by-step Explanation:
The sum of all the X's are 28 and if you divided that by 7 it is 4, and 4 times 50 is 200. And the highest number, which is 7, minus the smallest number which is 1 will be 6 and that times 50 is 300

Jean is multiplying 6 x 39. She decides to multiply 6 x 30 first, then add on 6 x 9. What property is Jean using to solve the problem? Her procedure would look like this mathematically
Answer:
Jean would add both results to get the final result of the multiplication of 6 x 39.
Step-by-step explanation:
6 x39 = 234
if the 3 in 39 is in the tenth position, then 6 x30 = 180
the number 9 in 39 stands as just 9, so, 6 x 9 = 54
The final multiplication of 6 and 39 = 180 + 54 = 234

1. Mr. Vasquez went to a restaurant with his family last weekend. He used his bank card and his bank account was debited $45. Represent the amount of money that was debited from his bank account using an integer.
Answer:
-$45
Step-by-step explanation:
INTERGER can said to represent a whole number in which this numbers can either be a positive INTERGER or a negative INTERGER. Therefore Based on the information if after using his bank card, his bank account was debited with the amount of $45 which means that the $45 that was debited will represent a NEGATIVE amount because it has lessen the amount in his bank account.
Therefore to represent the amount of $45 that was debited from his bank account using an INTERGER it will be -$45.

setting 7/3 equal to whuch ratio would result in a valid proportion 9/49 18/42 49/9
Answer:
49/9
Step-by-step explanation:
7/3 = 49/9
What do we multiply to the 7 in the numerator by to get 49?
- Well, 7. So we know the numerators have a factor of 7.
Then what do you multiply to 3 to get 9?
-This is 3.
We notice a pattern of the number multiplying itself, so the first fraction being (7/3)^2 would be 49/9
