Answer:
Assuming the choices are only of C and D, D would be the graph of the function.
Step-by-step explanation:
There are many things that would cause D to be the graph of f(x).
Firstly, D has the end behavior of a [tex]-x^{3}[/tex] function.
Secondly, it has correct zeroes
Lastly, Its y-intercept is -24, which is the case of the function f(x) as
[tex]f(0) = -24[/tex]
can someone help me
Step-by-step explanation:
For a parabola y = ax² + bx + c, the vertex occurs at x = -b / (2a).
For f(x), a = -2, b = 0, and c = 9. So the vertex is at:
x = -0 / (2×-2)
x = 0
At x=0:
f(0) = -2(0)² + 9
f(0) = 9
The maximum of g(x) is at 11.
So g(x) has a greater maximum value than f(x).
What set of fractions is ordered from least to greatest? A) 2/5,1/4,3/8 B) 3/8,2/5,1/4 C) 1/4,3/8,2/5 D) 3/8,1/4,2/5
Answer:
C) 1/4,3/8,2/5
Step-by-step explanation:
First of all, let's rewrite all the fractions listed as decimal numbers:
[tex]\frac{2}{5}=0.400[/tex]
[tex]\frac{1}{4}=0.250[/tex]
[tex]\frac{3}{8}=0.375[/tex]
So the correct order from least to greatest should be
0.250, 0.375, 0.400
Which corresponds in fractional form to
1/4, 3/8, 2/5
So the correct option is
C) 1/4,3/8,2/5
The correct set of fractions ordered from least to greatest is C) 1/4, 3/8, 2/5.
To determine the set of fractions ordered from least to greatest, we need to compare them by finding a common denominator or converting them to decimals.
Let's convert the fractions to decimals:
2/5 = 0.41/4 = 0.253/8 = 0.375Next, we order the decimals from smallest to largest:
1/4 (0.25)3/8 (0.375)2/5 (0.4)Therefore, the correct order from least to greatest is: C) 1/4, 3/8, 2/5.

What percentage of students earning degrees in 2009 were awarded a professional degree?
Answer:
2.07%
Step-by-step explanation:
92 out of a total of 3,204 graduates earned a professional degree. That works out to 0.0207, or 2.07%.
B) 2.87% of students earned a professional degree in 2009, calculated by dividing the number of professional degree holders by the total number of students.
To find the percentage of students earning a professional degree, divide the number of students with a professional degree (92) by the total number of students (3,204) and multiply by 100:
[tex]\[ \frac{92}{3,204} \times 100 \approx 2.87\% \][/tex]
Therefore, the correct answer is B) 2.87%.

Answer:
B
Step-by-step explanation:
B is correct. That "-7" will shift the graph of F(x) down by 7 units.
Answer:
B
Step-by-step explanation:
Given
y = f(x), then f(x) + c represents a vertical translation parallel to the y- axis.
• If c > 0 then translation up of + c units
• If c < 0 then translation down of - c units
Hence
g(x) = f(x) - 7

Rewrite the expression with rational exponents as a radical expression.
7 times x to the two thirds power
Answer:
9x^(3/2)=9 √(x^3 )
Step-by-step explanation:
We are given
9x^(3/2)
We have to write the expression in radical form, for that the power has to be a multiple of ½
=9x^(3*1/2)
As we can see now the power is a multiple of 1/2. ½ will convert to square root while 3 will become the power of radicand.
So, 9 will remain outside of the square root while x will be inside the square root while having power 3.
=9 √(x^3 )
Hence,
9x^(3/2)=9 √(x^3 )

What is 1/3 of 6 eggs and 18 ounces of flour
Answer:
2 eggs and 6 ounces of flour.
Step-by-step explanation:
To calculate this, we have to find 1/3 of 6 eggs and 18 ounces of flour separately.
So to calculate 1/3 of 6 eggs, multiply 6 by 1/3, which is to say divide 6 by(reciprocal) .Then you get 2 eggs.
Then similarly to calculate 1/3 of 18 ounces of flour, multiply 18 by 1/3, or divide it by 3. Then you get 6 ounces of flour.
So your answer is 2 eggs and 6 ounces of flour.

Help me find the lateral and the surface area I have to round to the nearest tenths if necessary
Answer:
L.A. = 157.5 in²S.A. = 241.8 in²Step-by-step explanation:
Lateral Area:
We have five congruent triangles with base = 7in and height h = 9in.
The formula of an area of a triangle:
[tex]A_triangle=\dfrac{bh}{2}[/tex]
Substitute:
[tex]A_\triangle=\dfrac{(7)(9)}{2}=\dfrac{63}{2}=31.5\ in^2[/tex]
The Lateral Area:
[tex]L.A.=5A_\triangle\to L.A.=5\cdot31.5=157.5\ in^2[/tex]
Surface Area:
S.A. = L.A. + B
L.A. - lateral area
B - area of a base
The base is the regular pentagon. The formula of an area:
[tex]B=\dfrac{a^2}{4}\sqrt{25+10\sqrt5}\approx1.72048a^2[/tex]
Substitute a = 7in:
[tex]B\approx1.72048(7^2)=84.303552\ in^2\approx84.3\ in^2[/tex]
The Surface Area:
[tex]S.A.=157.5+84.3=241.8\ in^2[/tex]

If we want to share the money in equal parts, we have to consider that Eli has 9 shares, Freda has 13 shares and Geoff has 18 shares. So, in total, we have to split the money in
[tex]9+13+18 = 40[/tex]
parts. So, each part is
[tex]\dfrac{800}{40} = \dfrac{80}{4} = 20[/tex]£
Now, we distribute the shares:
Eli has 9 shares, so she must receive [tex]20\cdot 9 = 180[/tex]£Freda has 13 shares, so she must receive [tex]20\cdot 13 = 260[/tex]£Geoff has 18 shares, so he must receive [tex]20\cdot 18 = 360[/tex]£Answer:
Eli gets £180
Freda gets £260
Geoff gets £360
Step-by-step explanation:
First, you need to make a ratio comparing their ages.
9 : 13 : 18 which is Eli : Freda : Geoff
Next, you need to work out the sum their ages (9+13+18) which is 40.
Then you divide the £800 (the amount that is being shared) by the sum of their ages 800÷40 which gives £20.And finally you need to multiply 20 by each section of the ratio.
So, 9×20 : 13×20 : 18 ×20 but then you need to simplify to get 180: 260 : 360.

Answer:
0.61
Step-by-step explanation:
The average rate of change of H(s) in the closed interval [ a, b ] is
[tex]\frac{H(b)-H(a)}{b-a}[/tex]
here [ a, b ] = [ 80, 100 ]
H(b) = H(100)
= 0.003 × 100² + 0.07 × 100 - 0.027
= 30 + 7 - 0.027 = 36.973
H(a) = H(80)
= 0.003 × 80² + 0.07 × 80 - 0.027
= 19.2 + 5.6 - 0.027 = 24.773
Hence
average rate of change = [tex]\frac{36.973-24.773}{100-80}[/tex] = [tex]\frac{12.2}{20}[/tex] = 0.61

In the diagram below, AB and bc are tangent to o. What is the measure of ac?
Answer:
Option D. [tex]150\°[/tex]
Step-by-step explanation:
we know that
The measurement of the outer angle is the semi-difference of the arcs it encompasses.
[tex]m\angle ABC=\frac{1}{2}[arc\ ADC-arc\ AC][/tex]
substitute the given values
[tex]30\°=\frac{1}{2}[210\°-arc\ AC][/tex]
[tex]60\°=[210\°-arc\ AC][/tex]
[tex]arc\ AC=210\°-60\°=150\°[/tex]
Answer:
Option (D) is correct.
Step-by-step explanation:
OA is perpendicular to AB
OC is perpendicular to BC
Radius from the center is perpendicular to the tangent.
In quadrilateral ABCO,
∠ABC+∠BCO+∠AOC+∠OAB=360°
30°+90°+∠AOC+90°=360°
∠AOC+210°=360°
∠AOC=360°-210°
∠AOC=150°
Hence, arc AC=150°
Thus, the correct answer is option (D)
Explain how you can use a number line to find the sum of -8.3 + 10.5. Please help!
Final answer:
You can use a number line to find the sum of -8.3 + 10.5 by marking both numbers on the line, moving left to the negative value, and then moving right by the positive value to find the sum.
Explanation:
To find the sum of -8.3 and 10.5 using a number line, you start by drawing a horizontal line and marking the positions of -8.3 and +10.5 on it. You then move from 0 to -8.3 as this is a negative number. To add 10.5, you move 10.5 units to the right. Because 10.5 is greater than 8.3, your final position will be to the right of zero which makes the sum positive.
Let's break down the steps:
Draw a number line with enough space to mark both -8.3 and +10.5.
Mark the point -8.3 on the left side of zero since it's a negative number.
From -8.3, move 10.5 units to the right because you are adding a positive number.
The point you land on is the sum of -8.3 + 10.5.
If you need to subtract numbers, change the sign of the number being subtracted and then add according to the rules of addition. For instance, to subtract 3 from 5, you would change 3 to -3 and then add: 5 + (-3) = 2.

No there cannot be the same number of stickers on each page.
Step-by-step explanation:
If you want to find out how many stickers need to be in every page to be even you would add all the stickers up. 6+6+9+10+11= 42. Take the 42 and divide it by 5 to see how many stickers would go in each page. This will give you 8.4. However since this number is a decimal it can't be split evenly in whole stickers for each page. Meaning that it wouldn't be possible for each page to have a evenly distributed number of stickers per each page.

Michael and Irene visit the pet store to buy some new things for their aquariums. Michael pays $10 for 4 new goldfish and one castle. Irene buys 4 new goldfish and 2 castles, which costs $16 altogether.
use elimination to solve the system...
Michael equation = 4x + y = 10
irenes equation = 4x + 2y = 16
what are the prices each fish and each castle?
Answer:
fish 1 dollar
castle 6 dollars
Step-by-step explanation:
4x + y = 10
4x + 2y = 16
Multiply the first equation by -1
- 4x - y = -10
4x + 2y = 16
------------------------
0x +y = 6
y = 6
This means the castle costs 6 dollars
Substitute this into the first equation
4x+y =10
4x+6=10
Subtract 6 from each side
4x+6-6=10-6
4x=4
Divide by 4
4x/4=4/4
x=1
This means each fish costs 1 dollar
So x=1 the answer is 1

Step-by-step explanation:
Because the length of ST is calculated using pythagorean theorem:
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
Where the square of the hypotenuse is equal to the sum of squares of the other two sides of a right triangle. In this case, the hypotenuse is ST and the other two sides are distances between S and T over the X and Y axis. Those are easily calculated:
[tex]x = |sx - tx| \\ y = |sy - ty| [/tex]
Where x is the distance between S and T over X axis and Y distance over Y axis, sx and tx are X coordinates of S and T, sy and ty are Y coordinates of S and T.
Using that formula, you get that y = 17 and x = 8.
Back to the pythagorean theorem, if we put those number in the formula of the pythagorean theorem, we get something like this:
[tex] {c}^{2} = {x}^{2} + {y}^{2} \\ {c}^{2} = {8}^{2} + {17}^{2} = 64 + 289 \\ {c}^{2} = 353 \\ c = \sqrt{353} [/tex]
And finally, the correct answer is in fact 353.

This triangle is a right triangle.
We know that the sum of the angles is 180°.
So:
90° + (x+23)°+ (x+13)° = 180°
90 + (x+23) + (x+13) = 180
(x+23)+(x+13) = 180-90
(2x+36) = 90
(2x) = 90-36
(2x) = 54
x = (54/2)
x = 27
=> x = 27
A school bus has 25 seats, with 5 rows of 5 seats. 15 students from the first grade and 5 students from the second grade travel in the bus. How many ways can the students be seated if all of the second-grade students occupy the first row? A. 25P20 B. 5P5 × 20P15 C. 5C5 × 25C14 D. 5P5 × 15P15 E. 5P5 × 25C15
Answer:
Option B. 5P5 × 20P15
Step-by-step explanation:
It is very important to remember that the second grade students are sitting in the front row, therefore, it is only necessary to organize 15 first grade students in 20 seats.
Permutations allow you to calculate the number of ways in which m objects can be arranged in n positions.
The permutation of m in n is written as:
nPm
Where n is the number of elements and m are chosen.
The way in which the 5 second grade students can be organized in the 5 seats is from the first row is:
5P5
Then, the number of ways in which 15 first-year students can be organized into 20 seats is:
20P15
Then, the number of ways to organize all students on the bus is the product of both permutations
5P5 * 20P15
