The equation h = –0.005x2 + x + 3 describes the path of a baseball hit into the outfield, where h is the height and x is the horizontal distance the ball travels.
a. What is the equation of the axis of symmetry?
b. What is the maximum height reached by the baseball?
c. An outfielder catches the ball three feet above the ground. How far has the ball traveled horizontally when the outfielder catches it?
Answer:
(a)x=100
(b)Maximum Height, h=53 Units
(c)x=200 Units
Step-by-step explanation:
Given the equation which describes the path of the baseball
[tex]h = -0.005x^2 + x + 3[/tex]
(a)Equation of the axis of symmetry
For a quadratic function of the form [tex]y=ax^2+bx+c[/tex], its equation of the axis of symmetry is determined by the equation:
[tex]x=-\dfrac{b}{2a}[/tex]
In the function given: a=–0.005, b=1
Therefore:
[tex]x=-\dfrac{1}{2*-0.005}=\dfrac{1}{0.01}\\\\x=100[/tex]
Equation of the axis of symmetry, x=100
(b)Maximum height reached by the baseball
The maximum height reached by the baseball occurs at the line of symmetry.
Therefore, when x=100
Maximum Height, [tex]h = -0.005(100)^2 + 100 + 3[/tex]
=53 Units
(c)When the height =3 feet, we want to determine the value of x.
[tex]h = -0.005x^2 + x + 3\\3 = -0.005x^2 + x + 3\\-0.005x^2 + x=0\\x(-0.005x + 1)=0\\-0.005x + 1=0\\-0.005x =-1\\$Divide both sides by -0.005\\x=200 Units[/tex]
Final answer:
The equation of the axis of symmetry is x = -100, the maximum height reached by the baseball is 103 feet, and to find the specific distance traveled when caught at 3 feet would require solving the quadratic equation given.
Explanation:
The equation h = –[tex]0.005x^2[/tex]+ x + 3 describes the path of a baseball hit into the outfield, where h is the height and x is the horizontal distance the ball travels.
a. What is the equation of the axis of symmetry?
The equation of the axis of symmetry for a quadratic equation in the form of [tex]ax^2 + bx + c[/tex] is given by x = –b/2a. Hence, for our equation, the axis of symmetry is x = –(1)/(2×–0.005) = –100.
b. What is the maximum height reached by the baseball?
The maximum height can be found by substituting the x-value of the axis of symmetry into the original equation. So, h = –[tex]0.005(100)^2[/tex] + 100 + 3 = 103 feet.
c. An outfielder catches the ball three feet above the ground. How far has the ball traveled horizontally when the outfielder catches it?
To find the horizontal distance when h is 3, we set the equation equal to 3: –[tex]0.005x^2 + x + 3 = 3.[/tex] Simplifying gives x values where the ball is at 3 feet off the ground. After simplification, one possible solution would be the distance before the ball reaches its peak. However, solving this particular quadratic may require a calculator for precise roots, implying the distances at which the ball is 3 feet high.

Jenny is making bracelets using different colored
beads. Jenny has 60 green beads and 105 blue
beads. What is the greatest number of identical
bracelets Jenny can make if she wants to use all of
the beads?
Answer:Jenny can make
18
identical necklaces, each containing 5 green and 6 blue beads.
Explanation:
Assume, each necklace contains
G
green and
B
blue beads and we have
N
such necklaces. All these variables are natural numbers.
Then we can establish the following equations in natural numbers:
N
⋅
G
=
90
N
⋅
B
=
108
Our task is to find a maximum
N
for which these two equations have a solution in natural numbers.
Obviously,
N
is a maximum common denominator of
90
and
108
.
To find the maximum common denominator of
90
and
108
, let's represent these two numbers as a product of prime numbers:
90
=
2
⋅
3
⋅
3
⋅

As we see, the maximum common denominator (a product of all prime numbers that are identical for both
90
and
108
) is
P

, we obtain the solution:
Maximum number of identical necklaces is
N
=
18
with each necklace containing
G
=
5
green beads and
B
=
6
blue beads.

Answer:
Situation 1 is exponential decay. Situation 2 is linear. Situation 3 is exponential growth.
Step-by-step explanation:
Situation 1 is exponential decay because it declined in a non linear way.
600-480=120 480-364=116
Situation 2 is linear because when it declined it has a dependent to another.
400-340=60 340-280=60
Situation 3 is exponential growth because is increases.
Danielle had planned her gift basket to be priced at $50 with a 40% gross margin. She forgot packaging costs which will be $3 per unit. If she still keeps the price at $50, how much will her gross margin percentage be after packaging costs?
a) 30%
b) 34%
c) 43%
d) 47%
The gross margin percentage after packaging costs would be a) 30%.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Danielle had planned her gift basket to be priced at $50 with a 40% gross margin.
let, The original price be 'x'.
Therefore, $50 is 140% of 'x' which is,
(140/100)×x = 50.
1.4x = 50.
x = 50/1.4.
x = 35.71.
Now, The packaging cost is $3 which makes the cost of the product 38.71.
So, (50/38.71)×100.
= 29% gross margin.

two similar trapezoids have areas of 180 cm2 and 45cm2. what is their ratio of similarity
The ratio of similarity between the two trapezoids is 2:1, which means that the linear dimensions of the larger trapezoid are twice those of the smaller one.
To find the ratio of similarity between two similar trapezoids with areas of 180 [tex]cm^2[/tex] and 45 [tex]cm^2[/tex], we use the principle that the ratio of the areas of similar figures is equal to the square of the ratio of their corresponding linear dimensions. In other words, if the ratio of similarity (scale factor) between the linear dimensions of two similar figures is 'k', then the ratio of their areas is '[tex]k^2[/tex]'.
Let the ratio of similarity be 'k'. Then we have 180/45 = k^2. Simplifying this, we get 4 = [tex]k^2[/tex] and thus, k = 2. This means the linear dimensions of the larger trapezoid are twice those of the smaller one.
Therefore, the ratio of similarity between the two trapezoids is 2:1.
If you invest $100,000 in an account earning 8% interest compounded annually, how long will it take until the account holds $300,000?
(Round to the nearest 0.1 of a year.)
( answergoes here ) ______________________
Compound interest formulas:
A=P(1+rn)ntA=P(1+r/n)^nt and A=Pe^rt
We have been given that you invest $100,000 in an account earning 8% interest compounded annually. We are asked to find the time it will take the amount to reach $300,000.
We will use compound interest formula to solve our given problem.
[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,
A = Final amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.
[tex]8\%=\frac{8}{100}=0.08[/tex]
[tex]300,000=100,000(1+\frac{0.08}{1})^{1\cdot t}[/tex]
[tex]300,000=100,000(1.08)^{t}[/tex]
[tex]\frac{300,000}{100,000}=\frac{100,000(1.08)^{t}}{100,000}[/tex]
[tex]3=(1.08)^{t}[/tex]
[tex](1.08)^{t}=3[/tex]
Let us take natural log on both sides of equation.
[tex]\text{ln}((1.08)^{t})=\text{ln}(3)[/tex]
Using natural log property [tex]\text{ln}(a^b)=b\cdot \text{ln}(a)[/tex], we will get:
[tex]t\cdot \text{ln}(1.08)=\text{ln}(3)[/tex]
[tex]\frac{t\cdot \text{ln}(1.08)}{\text{ln}(1.08)}=\frac{\text{ln}(3)}{\text{ln}(1.08)}[/tex]
[tex]t=\frac{1.0986122886681097}{0.0769610411361283}[/tex]
[tex]t=14.274914586[/tex]
Upon rounding to nearest tenth of year, we will get:
[tex]t\approx 14.3[/tex]
Therefore, it will take approximately 14.3 years until the account holds $300,000.

The probability that a randomly selected person who can bike to school is a boy is 7/16 or 0.4375, which means there is a 43.75% chance that the person is a boy.
Explanation:To determine the probability that a randomly selected person who can ride a bike to school is a boy, we will use the provided data.
Looking at the data table, we can see there are 7 boys who can bike to school, and the total number of students who can bike to school is 16 (this is the sum of boys and girls who can bike). In probability terms, the boys who can bike are the 'favorable outcomes' and the total students who can bike are the 'possible outcomes'.
Probability is calculated by dividing the number of favorable outcomes by the number of possible outcomes. Thus, the probability a randomly selected person can ride a bike to school is a boy is 7/16, or approximately 0.4375.
This means, if we were to randomly select a person who can bike to school, there is a 43.75% chance that the person is a boy. I hope this explanation helps explain how to determine probability using a data set.

the lines on a coordinate plane are perpendicular.
perpendicular lines form what type of angles?
Final answer:
Perpendicular lines on a coordinate plane intersect to form right angles, which are precisely 90°. The slopes of perpendicular lines are negative reciprocals of each other.
Explanation:
When two lines on a coordinate plane are described as being perpendicular, this means they intersect to form right angles, which are angles of 90°. It's important to recognize that perpendicular lines have slopes that are negative reciprocals of each other. For example, if one line has a slope of 2, a line perpendicular to it would have a slope of -1/2. These slopes ensure that the angles formed between the lines are exactly 90 degrees.
In geometry and physics, this concept is further explored with orthogonal vectors, which are two vectors with directions that differ by exactly 90°, synonymous with perpendicular vectors. Their importance lies in various applications, such as breaking down a force into components acting along perpendicular axes.
