Answer:
[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]
Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.
Step-by-step explanation:
We are given that a frog leaps two feet, with the highest point in the jump being six inches.
Assuming the frog starts at (0,0), we want to find a quadratic function in vertex form for the path of the jump.
First, we will convert the length of the jump to inches. Two feet is equivalent to 24 inches.
Next, since the frog started at (0, 0), in order to jump a length of 24 inches, it must have ended at (0, 24). These two points will also be our two roots: x = 0 and x = 24. We can use the factored form of a quadratic:
[tex]f(x)=a(x-p)(x-q)[/tex]
Where p and q are the roots.
Substitute in the roots:
[tex]f(x)=a(x-0)(x-24)=ax(x-24)[/tex]
Now, since the frog reached a maximum height of six inches, the y-coordinate of the function at its vertex point is 6.
Since a parabola is symmetrical along its axis of symmetry, the axis of symmetry is always halfway between the two roots.
Therefore, the x-coordinate of our vertex is:
[tex]\displaystyle x=\frac{24-0}{2}=12[/tex]
So, when x = 12, f(x) = 6. Substitute:
[tex]6=a(12)(12-24)[/tex]
Solve for a:
[tex]\displaystyle- 144a=6\Rightarrow a=-\frac{1}{24}[/tex]
Therefore, our function is:
[tex]\displaystyle f(x)=-\frac{1}{24}x(x-24)[/tex]
Now, we can place this into vertex form:
[tex]\displaystyle f(x)=a(x-h)^2+k[/tex]
Where a is the leading coefficient and (h, k) is the vertex.
Our leading coefficient is -1/24, and the vertex is (12, 6). Hence, our function is:
[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]
Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.

You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth.
The probability of spinning an odd number, not flipping heads, then not spinning a 6 is
__
Using it's concept, it is found that the probability of spinning an odd number, not flipping heads, then not spinning a 6 is:
[tex]p = \frac{20}{81} = 24.69\%[/tex]
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
There are 5 odd numbers in the spinner, out of 9, hence the probability of spinner an odd number is 5/9.The coin is fair, hence the probability of flipping tails = not heads is of 1/2.Out of the 9 numbers in the spinner, only one is six, hence the probability of not spinning a 6 is of 8/9.Then, the probability of the compound event is:
[tex]p = \frac{5}{9} \times \frac{1}{2} \times \frac{8}{9} = \frac{20}{81} = 24.69\%[/tex]

Skye made a deposit of $625 into an account that earns 4% simple interest for 6 years. How much did Skye earn in interest at the end of 6 years?
Answer:
She will earn 150$
Step-by-step explanation:
4% = 0.04
0.04 x $625 = 25
Now we divide 25 by the number of years, which is 6.
6 x 25 = 150$
Therefore, Skye earns 150$ from interest over the course of 6 years.

Answer:
1: Tip, $2.23
2: Tax, $0.74
3: Total, $17.87
4: Split, $5.95
Step-by-step explanation:
To find the tip, you must multiply the tip percentage by the bill, (which has not been taxed yet). The tip is 15%, which is equivalent to 0.15. The tip multiplied by the bill (0.15×14.90) equals $2.23.
To find the tax, you do the same as you did with the tip. The tax is 5%, which equals 0.05. The tax multiplied by the bill, (0.05×14.90) equals $0.74. The total cost is the bill, tip, and tax added together, (14.90+2.23+0.74) equals $17.87. To find out how much each person will pay equally, you must divide the total bill by the amount of people, (17.87÷3) which equals $5.95.

m∠a =

Find the measurement of ∠b.
m∠b +
° +
° =180°
m∠b =
°
Answer:
Step-by-step explanation:
We know that a straight angle is equal to 180°. Therefore, 120°+(a)=180°
We can solve for (a) by subtracting 120 from 180, which is 60.
180-120=60
m∠a+120°=180°
m∠a=60°
We know that the sum of all angles in a triangle is 180°.
Therefore, (a)+60°+(b)=180°
We know that (a) is equal to 60°, so our new equation is:
60°+60°+b=180°
60+60=120
180-120=60
m∠b+60°+60°=180°
m∠b=60°

Answer: A. $30.00
Step-by-step explanation:
1. Find the common difference, or by how much the value changes per pound. Divide the price of the sales by the amount of pounds to find the rate. The rate must be $2.50 since 10 ÷ 4 = 2.5. To confirm, use 2 or 3 pairs of values. 15 ÷ 6 = 2.5, which confirms that the common difference is 2.5. This means that every pound of asparagus is $2.5.
2. Now that the rate is known, multiply it by 12. 2.5 * 12 = $30.00, which is the final answer.
Each of these is proportional to the other. Meaning, if you put the price over the pounds, then you get a fraction that remains consistent throughout the entire table and beyond.
[tex]\frac{price}{pounds}=\frac{10}{4} =\frac{5}{2}[/tex] so [tex]\frac{5}{2}[/tex] will be our constant ratio. With our formula, we know that the two equal each other, so [tex]\frac{price}{pounds}=\frac{5}{2}[/tex].
[tex]\frac{x}{10}=\frac{5}{2}\\[/tex] so [tex]2x=50\\x=25[/tex]
[tex]\frac{x}{12}=\frac{5}{2}[/tex] so [tex]2x=60\\x=30[/tex]
12 pounds of asparagus is $30.00

Step-by-step explanation:
Now we have to,
→ Find the required value of y.
The equation is,
→ 24 = y + 17.5
Then the value of y will be,
→ 24 = y + 17.5
→ y + 17.5 = 24
→ y = 24 - 17.5
→ [ y = 6.5 ]
Hence, the value of y is 6.5.

Answer:
area =12
Step-by-step explanation: you don't need to use all 4 numbers just used the base which is 8 then times it with 3 which gives you 24 then divided it by 2 which gives you 12.
Answer:
Area=12
Step-by-step explanation:
You take the height which is 3 and multiply it by the base which is 8. Then you get 24 and divide it by 2 which gives you 12.
