The height of a batted baseball is modeled by the equation h(t) = -16t²+64t+6, where t is measured in seconds and h is measured in feet.
a.) At what time in seconds does the ball attain its maximum height?
b.) What is the maximum height attained by the ball? (Give your answer in feet.)
Answer:
[tex] \frac{dh}{dt} = - 32t + 64 = 0 \\a) \: t = \frac{ - 64}{ - 32} = 2 \\ \\ b = - 16 \times 4 + 64 \times 2 + 6 = - 64 + 2 \times 64 + 6 = 64 + 6 = 70[/tex]
Answer:
a) t = 2 seconds
b) 70 feet
Step-by-step explanation:
First of all, we are going to take the derivative of the function (which is a displacement function) to make find its velocity function.
[tex]h(t) = -16t^{2} +64t+6[/tex]
To find the derivative of the equation, we must multiply the coefficient by the exponent and then minus one from the exponent for each term.
[tex]v(t)=(-16)(2)t^{2-1} +64(1)t^{1-1}+6(0)t^{0-1} \\v(t) = -32t +64[/tex]
Now we can substitute in v=0
This is because the ball is at the top of its parabola path, it is the turning point and the slope is 0. The velocity physically speaking would also be 0 at the very top of its path.
[tex]0=-32t+64[/tex]
Rearrange and we get:
[tex]32t = 64\\t=2[/tex]
Ball attains maximum height at 2 seconds.
To find the maximum height, we now just have to substitute back in the time into the original equation to find the height.
[tex]h(t) = -16t^{2} +64t+6[/tex]
[tex]h(2) = -16(2)^{2} +64(2)+6\\h(2)=-64+128+6\\h(2) = 70[/tex]
The maximum height attained is 70 feet.

At the mall, Jamie buys a pair of jeans for $34 and then a shirt for $12. The store is having a 25%
off sale. You will then have to pay 8% sales tax. What is the total amount you will pay?
Answer:
$37.26
Explanation:
firstly, we find the total original price: $34 + $12 = $46.
next, we can multiply this by 100% - 25% = 75% to find the discounted price:
$46 × 75%
= $46 ÷ 100 × 75
= $34.50
finally, add on the sales tax which is 100% + 8% = 108%:
$34.50 × 108%
= $34.50 ÷ 100 × 108
= $37.26

Two angles have a supplementary relationship. The measure of one angle is 14°. What is the measure of the second angle?
Answer:
166°
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees
That being said, we can find the measure of the missing angle by subtracting the measure of the given angle by 180
(the giving angle having a measure of 14°)
so missing angle = 180 - 14
180 - 14 = 166
Hence, the measure of the second angle 166°

A certain species of deer is to be introduced into a forest, and wildlife experts estimate the population will grow to P(t)=(493)4 ^1/2, where t represents the number of years from the time of introduction. What is the quadrupling-time for this population of deer?
Answer:
The answer is "2 years".
Step-by-step explanation:
Given:
[tex]\to P(t) = 493\times4^{\frac{t}{2}}[/tex]
when t=0
[tex]P(0) = 493\times4^{\frac{0}{2}}\\\\[/tex]
[tex]= 493\times4^0\\\\= 493\times 1\\\\= 493 \\[/tex]
Calculating the quadrupling time:
[tex]\to P(t) = 4 \times P(0) \\\\[/tex]
[tex]= 4\times 493 \\\\= 1972[/tex]
Solving
[tex]\to 1972= 493\times4^{\frac{t}{2}} \\\\\to 4 = 4^{\frac{t}{2}}\\\\\to \frac{t}{2} = 1\\\\\to t = 2\ years \\\\[/tex]

A quantity with an initial value of 5700 decays exponentially
at a rate of 7.5% every 2 days. What is the value of the
quantity after 234 hours, to the nearest hundredth?
Answer:
36.5625
Step-by-step explanation:
so, if it decays at a rate of 7.5% every 2 days, and we have 234 hours, we do the following, 234/24, since there are 24 hours in a day, that gives us 9.75, "7.5% every 2 days" so we do this, 9.75/2 = 4.875
4.875 * 7.5 = 36.5625
i migt be wrong, but i'm pretty sure this is the answer, i'm not saying this is the answer like some people do, please let me know if i'm wrong.
Answer:
3897.77
Step-by-step explanation:
Decays 7.5%→r=0.075 (divide by 100)
Decays every 2 days: exponent of t/2
(where t is in days)
function- f(t)=5700(1−0.075) ^t/2
234 hours→234/24→9.75 days
Plug in t=9.75
f(9.75)=5700(1−0.075) ^9.75/2
3897.76635734

104+76=180 and a circle is 360
- Thx for the points have a nice day! ^ω^
Answer:
A. 76
B. 256
Step-by-step explanation:
DF is a diameter so that means the right side of the
circle measure 180 degrees. Angle DGE measures 104, since that the central angle that means Arc DE measures 104 also.
Using arc addition, part of the right side measure 104 so that means the remaining arc must add up to 180.
[tex]104 + x = 180[/tex]
[tex]x = 76[/tex]
Arc EF measure 76.
2. A circle has 360 degrees in it. We are asked to find the measure of the circle expect the Arc ED.
Arc ED measures 104 so
[tex]360 - 104 = 256[/tex]

What is Trigonometry?Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles. The ratios used to study this relationship are called trigonometric ratios, namely, sine, cosine, tangent, cotangent, secant, cosecant.
Trigonometric RatiosThere are basic six ratios in trigonometry that help in establishing a relationship between the ratio of sides of a right triangle with the angle. If θ is the angle in a right-angled triangle, formed between the base and hypotenuse, then
sin θ = Perpendicular/Hypotenuse
cos θ = Base/Hypotenuse
tan θ = Perpendicular/Base
The value of the other three functions: cot, sec, and cosec depend on tan, cos, and sin respectively as given below.
cot θ = 1/tan θ = Base/Perpendicualr
sec θ = 1/cos θ = Hypotenuse/Base
cosec θ = 1/sin θ = Hypotenuse/Perpendicular
Given:
H= 12
angle= 26°
Using Trigonometry
sin 26 = B/ H
0.4383= x/ 12
x= 5.26
Hence, the value of x is 5.26

The radical expression √x/2 e is equivalent to the given product, which is the correct option(C).
What are the radical expressions?Any expression that contains a radical symbol is considered a radical expression. Unknown variables, numbers, and arithmetic operators make up a radical expression. It contains no equality or inequality symbols.
To find the square roots, cubic roots, and higher, radical symbols are used. For example, √7, √6, and √11 are in the radial form.
The radical expression is given in the question, as follows:
√(3/x)·√(x²/12)
Combine the term in radicals of the above expression,
√[(3/x) × (x²/12)]
Reduce the likewise variables in the expression,
√(x/4)
Apply the square root property, and we get
√x/2
Thus, the radical expression √x/2 e is equivalent to the given product.

Step-by-step explanation:
Search "What is the definition, formula and example problem of permutation, combination and probability
Answer:
Permutation:
In mathematics, a permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements. The word "permutation" also refers to the act or process of changing the linear order of an ordered set.
Formula:
[tex]nPr=\frac{n!}{(n-r)!}[/tex]
Example:
Permutations are the different ways in which a collection of items can be arranged. For example, the different ways in which the alphabets A, B and C can be grouped, taken all at a time, are ABC, ACB, BCA, CBA, CAB, BAC. Note that ABC and CBA are not the same as the order of arrangement is different.
Combination:
In mathematics, a combination is a selection of items from a collection, such that the order of selection does not matter.
Formula:
[tex]nCr=\frac{n!}{r!(n-r)!}[/tex]
Example:
Combination: Picking a team of 3 people from a group of 10.
C(10,3) = 10!/(7! * 3!) = 10 * 9 * 8 / (3 * 2 * 1) = 120.
Probability:
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
Formula:
Conditional Probability P(A | B) = P(A∩B) / P(B)
Bayes Formula P(A | B) = P(B | A) ⋅ P(A) / P(B)
Example:
Probability is the likelihood or chance of an event occurring. For example, the probability of flipping a coin and its being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½.
Chris is working on a stained-glass project and needs to form a triangle with sides of 8, 12, and 15 inches out of lead cane to enclose the glass. To the nearest tenth of a degree, what is the largest angle he needs to create using the lead caning?
Answer:
The largest angle needed is [tex]95.1^{o}[/tex].
Step-by-step explanation:
To determine the larges angle as required, let us apply the cosine rule.
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2ab Cos C
Since in triangles, the longest side is opposite to the largest angle, then;
[tex]15^{2}[/tex] = [tex]8^{2}[/tex] + [tex]12^{2}[/tex] - 2(8 x 12) Cos θ
225 = 64 + 144 - 192 Cos θ
225 = 208 - 192 Cos θ
192 Cos θ = 208 -225
192 Cos θ = -17
Cos θ = [tex]\frac{-17}{192}[/tex]
Cos θ = -0.08854
θ = [tex]Cos^{-1}[/tex] -0.08854
= 95.07962
θ = [tex]95.1^{o}[/tex]
The largest angle needed is [tex]95.1^{o}[/tex].
