Help with this (calculus)
(a) h(t) is quadratic, so we can complete the square to write
h(t) = 100 + 40 t - 5 t²
h(t) = 100 - 5 (t² - 8 t)
h(t) = 100 - 5 (t² - 8 t + 16 - 16)
h(t) = 100 + 80 - 5 (t² - 8 t + 16)
h(t) = 180 - 5 (t - 4)²
The squared quantity is always non-negative, which means h(t) has a maximum value of 180 m.
(b) First, find when the projectile hits the ground, which happens when h(t) = 0:
0 = 180 - 5 (t - 4)²
180 = 5 (t - 4)²
36 = (t - 4)²
± 6 = t - 4
t = -2 OR t = 10
Omit the negative solution. The velocity of the ball at t = 10 s is equal to the derivative at the point, h' (10).
[tex]h'(10)=\displaystyle\lim_{t\to10}\frac{h(t)-h(10)}{t-10}[/tex]
[tex]h'(10)=\displaystyle\lim_{t\to10}\frac{(180-5(t-4)^2)-80}{t-10}[/tex]
[tex]h'(10)=\displaystyle\lim_{t\to10}\frac{100+40t-5t^2}{t-10}[/tex]
[tex]h'(10)=\displaystyle-5\lim_{t\to10}\frac{(t+2)(t-10)}{t-10}[/tex]
[tex]h'(10)=\displaystyle-5\lim_{t\to10}(t+2)=-60[/tex]
So the projectile has a downward velocity of 60 m/s at the moment it touches the ground.
Hello!
Find the maximum height by finding the maximum of the function, where the derivative switches from positive to negative. Find the derivative of the equation:
h(t) = 100 +40t -5t²
Power rule:
h'(t) = 40 - 10t
Set the equation equal to 0:
0 = 40 - 10t
-40 = -10t
t = 4
Test values on both sides of 4 to ensure that there is a maximum at this x value:
40 - 10(3) = 10
40 - 10(5) = -10
Therefore, the derivative switches from positive to negative. There is a maximum at t = 4. Find the height by plugging in this value for time into the original equation:
h(4) = 100 + 40(4) - 5(4)²
h(4) = 100 + 160 - 80
h(4) = 180 meters
Find the velocity when it hits the ground. Begin by finding the time necessary for the object to hit the ground:
0 = 100 + 40t - 5t²
Rearrange and factor:
0 = -5t² + 40t + 100
0 = (5t + 10)(-t + 10)
Set each factor equal to 0:
5t + 10 = 0
t = -2
-t + 10 = 0
t = 10
Therefore, the object takes 10 seconds to reach the ground. Plug this into the derivative of the equation (solved for earlier), which is the velocity:
h'(t) = 40 - 10t
h'(10) = 40 - 10(10)
h'(1) = -60 m/s. This is the *downward* velocity when the object hits the ground.

What is a triangle?A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.
For the given situation,
The diagram below shows the travelling of ship from A to C.
Let sides a = 30 miles, c = 200 miles,
The measure of angle B is [tex]\angle CBA = 180-30[/tex] [∵ Supplementary angle]
⇒ [tex]\angle CBA = 150[/tex]
Here two sides and one angle of triangle are provided.
The other side of the triangle, that is the distance traveled by the ship can be found by using the law of cosines.
The formula of law of cosines,
[tex]b = \sqrt{a^{2}+c^{2}-2ac (cosB ) }[/tex]
On substituting the values,
⇒ [tex]b = \sqrt{30^{2}+200^{2}-2(30)(200) (cos150 ) }[/tex]
⇒ [tex]b = \sqrt{900+40000-12000(-0.8660 ) }[/tex]
⇒ [tex]b = \sqrt{40900+10392 }[/tex]
⇒ [tex]b = \sqrt{51292}[/tex]
⇒ [tex]b=226.477[/tex] ≈ [tex]226.48[/tex]
Hence we can conclude that the distance of the ship from the beginning is 226.48 miles far apart.

What is the slope of a line that passes through the
points (-2, 12) and (-6, 8)?
Answer:
m = 1
Step-by-step explanation:
Use the given points to solve the slope formula.
(-2, 12) (-6, 8)
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
m is the slope, x is the first number in the given point, and y is the second. (It doesn't matter which point you choose to be x1,y1 or x2,y2)
[tex]m=\frac{8-12}{-6-(-2)}[/tex] (subtracting negative cancels out and becomes adding a positive)
[tex]m=\frac{-4}{-4}[/tex] (the negatives cancel out and become positive)
m = 1

The table which represents a linear function is table 4.
What is a function?
Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
The tables in the question
Now,
The table that represents a linear function is:
X Y
1 3
2 7
3 11
4 15
The reason this is a linear function is that for each increase in the input value of X by 1, the output value of Y increases by a constant amount of 4. In other words, the rate of change of Y with respect to X is constant at 4, indicating a linear relationship between the two variables.
Therefore, the answer of the function will be table 4.

Please help me figure these problems out with the correct answers the last guy said they were all not triangles and my teacher said they were incorrect who ever answers and explains correctly gets 31 points and gets marked brainliest you have all the time you need so answer wisely. This shouldn't take long don't answer something your not similar with.
Problem 1
Answer: Yes a triangle can be formed with side lengths 5,5,3
--------------------
Explanation:
Take any two sides and add them up. If we get a sum larger than the third side, then a triangle is possible. This is the triangle inequality theorem.
5+5 = 10 is larger than 3
5+3 = 8 is larger than 5
This shows a triangle is possible. The triangle is isosceles because two sides are the same length.
==========================================================
Problem 2
Answer: Yes a triangle can be formed with side lengths 8,8,8
--------------------
Explanation:
This triangle is equilateral because all sides are the same length.
Take any two sides, add them up, and you'll find the sum is larger than the third side.
==========================================================
Problem 3
Answer: No a triangle cannot be formed with sides 7,8,15
--------------------
Explanation:
Yes it is true that
8+15 = 23 is larger than 7
7+15 = 22 is larger than 8
but
7+8 = 15 is not larger than 15
So this means a triangle is not possible.
Imagine you had 3 strips of paper that were 7 inches, 8 inches and 15 inches long. The 7 and 8 inch strips add to 15 inches, but those two smaller strips only form a straight line. We cannot pull them so a triangle forms. If we did, then the third side would be smaller than 15 inches. This is one way to get hands on to see why the triangle inequality theorem works.
==========================================================
Problem 4
Answer: Yes a triangle is possible with side lengths 5,6,10
--------------------
Explanation:
Same idea as before. We can take any two sides, add them, and get a sum larger than the third side. A triangle is possible.

Answer:
D. If it is a pentagon, then it has five sides. If the polygon has five sides, then it is a pentagon
Step-by-step explanation:
Given statements;
A polygon is a pentagon if and only if it has five sides.
From the statement we see that a pentagon has 5 sides. A body of this structure with 5 sides can be classified as a polygon.
Therefore, this bi-conditional statement is premised on two "if"s,
If it is a pentagon then we are dealing with a body with 5 sides.
And if such body has five sides, it is a polygon called pentagon
The correct option is D
Choice A, B and C are logically flawed.
A. If it is a pentagon, then it has five sides. If it is a polygon, then it is a pentagon.
The emboldened part we do not know.
B. If it is a pentagon, then it is a polygon. If it is a polygon, then it is a pentagon
The emboldened part is flawed.
C. If it is a pentagon, then it is a polygon. If it is a polygon, then it has five sides.
We do not know if all pentagons have 5 sides.
The bus routes in a city run on average every 15 minutes. The route times can vary by three minutes. Which absolute value equation can be used to find the maximum and minimum wait times at a bus stop?
Answer:
[tex]Max = 18\ mins[/tex]
[tex]Min = 12\ mins[/tex]
Step-by-step explanation:
Given
[tex]Time = 15\ mins[/tex]
[tex]Variation = 3\ mins[/tex]
Required
Determine the max and min values
The max value is calculated as thus:
[tex]Max = Time + Variation[/tex]
[tex]Max = 15\ mins + 3\ mins[/tex]
[tex]Max = 18\ mins[/tex]
The min value is calculated as thus:
[tex]Min = Time - Variation[/tex]
[tex]Min = 15\ mins - 3\ mins[/tex]
[tex]Min = 12\ mins[/tex]
