Answer:
there is a cluster from 1-4
there is a gap from 5-7
The spread is from 1-8
Step-by-step explanation:
These are all true if you look... there is a bunch from 1-4, there is none from 5-7, and all of them are within 1-8, but the highest amount isn't at 3.
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.

The degree of the polynomial function f(x) is 4.
The roots of the equation f(x)=0 are −2, −1, 1 and 3.
Which graph could be the graph of f(x)?
Answer:
Option A
Step-by-step explanation:
Degree of the polynomial function = 4
That means highest degree term of the given polynomial has power = 4
If the roots of a quadratic polynomial are a, b, c, d then the polynomial function will be,
f(x) = (x - a)(x - b)(x - c)(x - d)
It's given in the question that roots are x = -2, -1, 1 and 3
Therefore, polynomial function will be,
f(x) = (x + 2)(x + 1)(x - 1)(x - 3)
From the given options, graph A shows that the graph intersects the x-axis at x = -2, -1, 1 and 3
Therefore, Option A will be the answer.

Step-by-step explanation:
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
i hope this helps! :D
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°

Step-by-step explanation:
1000 chicken wings weighs 3000 g how many grams in one chicken wing weigh
Answer:
3 grams are in one chicken wing
Step-by-step explanation:
Set up an equation:
Variable x = grams per 1 chicken wing
1000/3000 = 1/x
Cross multiply
1000 × x = 3000 × 1
1000x = 3000
Divide both sides by 1000 to isolate the variable x
x = 3
Answer:
3
Step-by-step explanation:
3000/1000=3
how do you solve 5% of 58
Answer:
2.9
Step-by-step explanation:
5% of 58
58 × 5 ÷ 100 = 2.9
Step-by-step explanation:
Convert 5% to a fraction first.
[tex]5\% = \frac{5}{100} \\ = \frac{1}{20} [/tex]
5% of 58
=
[tex] \frac{1}{20} \times 58 \\ = \frac{58}{20} \\ = \frac{29}{10} \\ = 2.9[/tex]

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].
. The perimeter of a square is 8y – 12. The area of the square is 100 square units. What is the value of y?
Answer:
y = 6.5 units
Step-by-step explanation:
Let L be the length of sides of the square.
Given the following data;
Perimeter of square = 8y - 12
Area of square = 100 square units
To find the value of y;
Area of a square = L²
Substituting into the formula, we have;
100 = L²
L = √100
L = 10 units
Mathematically, the perimeter of a square is given by the formula;
Perimeter of a square = 4L
Substituting into the formula, we have;
8y - 12 = 4*10
8y - 12 = 40
8y = 40 + 12
8y = 52
y = 52/8
y = 6.5 units

Answer:
[tex]\text{log}_a(1.5^{-1})=\frac{-9}{5}[/tex]
Step-by-step explanation:
Given;
[tex]\text{log}_a(2)=\frac{1}{2}[/tex]
[tex]\text{log}_a(3)=5[/tex]
By using logarithmic properties,
[tex]\text{log}_a(2)-\text{log}_a(3)=\frac{1}{2}-5[/tex]
[tex]\text{log}_a(\frac{2}{3})=\frac{1}{2}-5[/tex]
[tex]\text{log}_a(\frac{1}{\frac{3}{2}})=\frac{1}{2}-5[/tex]
[tex]\text{log}_a(\frac{1}{1.5})=\frac{1}{2}-5[/tex]
[tex]\text{log}_a(1.5^{-1})=\frac{1-10}{5}[/tex]
[tex]\text{log}_a(1.5^{-1})=\frac{-9}{5}[/tex]

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]
